Introduction

You may have heard of current clinical trials striving to uncover new treatments for autoimmune encephalitis (AE). An exciting trial to look out for is the ExTINGUISH Trial — a promising clinical study in this field.

The Extinguish trial is set to evaluate the use of a monoclonal antibody in the treatment of anti-NMDAR Encephalitis, which is a subtype of AE. Recent successes in employing monoclonal antibodies, notably in treating complex neurological conditions like Alzheimer’s disease1, emphasize the potential breakthrough that this trial could signify.

The main goal of the ExTINGUISH trial is to assess the effectiveness of a specific monoclonal antibody, known as inebilizumab, in treating anti-NMDAR encephalitis2. Monoclonal antibodies are routinely utilized in the treatment of AE. However, the goal of researchers is to continue to make this technology better and more effective for patients.

What is inebilizumab?

In patients with autoimmune encephalitis, the body’s immune system mistakenly attacks the brain, causing inflammation. Inflammation causes the immune system to produce a kind of protein called an antibody. Typically, these antibodies flag things like invading viruses or bacteria for the immune system to find and destroy. In AE, antibodies play a harmful role by mistakenly flagging brain cells. As the immune system attacks the brain, patients with AE develop a host of symptoms, like seizures, mood changes, altered mental status, and memory loss3.

In an attempt to alleviate the symptoms of AE, scientists have long been interested in designing a drug that would prevent the immune system from making harmful antibodies. Recent research suggests that the best approach might be to fight fire with fire: by engineering a monoclonal antibody that specifically targets the immune cells responsible for generating the harmful antibodies at the onset of AE4. A monoclonal antibody is a special kind of protein created in a lab that can target and attach to specific harmful substances or cells in the body, helping the immune system to identify and neutralize them (figure 1).

A new monoclonal antibody called inebilizumab has shown promise as a potential treatment for a subtype of AE, called anti-NMDAR encephalitis5.

Inebilizumab was recently approved for the treatment of neuromyelitis optica spectrum disorder (NMOSD), a rare autoimmune disorder affecting the central nervous system.

The fact that this monoclonal antibody is proving effective for patients with another autoimmune neurological disorder suggests it could work for AE as well6.

How is inebilizumab different from current monoclonal antibody treatments for anti-NMDAR Encephalitis ?

Another monoclonal antibody called rituximab is already a secondary treatment option for anti-NMDAR encephalitis that is used when first-line therapies fail or produce an adequate response7. Rituximab works by targeting one group of immune cells making the harmful antibodies in AE, called B cells. While rituximab can help manage anti-NMDAR encephalitis for some patients by getting rid of B cells, it does not work for everyone7. This could be because B cells live for a short time, but produce other longer-lived versions of themselves, called plasma cells and plasmablasts.

Moreover, monoclonal antibodies work by recognizing a specific marker on the cells that they aim to neutralize. For instance, rituximab targets all cells that express a specific marker called CD20 on their surface. While rituximab removes the B cells that express CD20, it leaves the plasma cells and plasmablasts in the body because they often lack the CD20 surface marker. Therefore, these long-lasting immune cells can continue to produce the problematic antibodies that lead to anti-NMDAR encephalitis8.

This is where inebilizumab comes into play. Inebilizumab targets a different surface marker called CD19. This marker is not only expressed by B cells, but it is also present on the surface of their longer-lasting progeny, the plasma cells and plasmablasts. Therefore, by targeting all cells that express CD19 inebilizumab is capable of neutralizing the original B cells as well as the longer-lasting plasma cells and plasmablasts (figure 2)8.

Figure 2. Inebilizumab inhibits the production of plasma cells and plasmablasts that produce harmful antibodies against the brain.

By getting rid of more of the immune cells producing harmful antibodies against the brain, inebilizumab may be an even more effective treatment for anti-NMDA encephalitis than rituximab8,9.

The ongoing clinical trial

Clinical trials are scientific tests for new medications or treatments to determine if promising new treatments are more effective than what is currently on the market. In what are called placebo-controlled clinical trials, some participants get the new treatment, while others get a placebo. A placebo is a version of the treatment without the active ingredient of the medicine in it. This helps researchers compare how well the real treatment works by checking if there is a noticeable difference between those who get the medicine and those who get the placebo. It is a way to make sure the treatment is genuinely effective. Following the trial’s conclusion, should the new treatment prove effective, members of the placebo group will likewise be granted access to it.

The clinical trial for inebilizumab is called the ExTINGUISH Trial. The ExTINGUISH Trial aims to assess the effectiveness of inebilizumab compared to a placebo in treating moderate-to-severe NMDAR encephalitis alongside standard therapies. This trial involves 120 participants with moderate to severe anti-NMDAR encephalitis and evaluates patient outcomes using various measures that assess their daily functioning, brain abilities, quality of life, and predict how they may progress over a 16-week period. The study also aims to find biological markers that can be used to predict how well the treatment will work in future patients. Doctors and researchers will monitor levels of the anti-NMDAR antibodies responsible for the symptoms of AE as well as a measure of activation of the B cells that produce these harmful antibodies2,10. This will allow doctors to determine whether patients with certain levels of these substances in their body respond better or worse than others.

Ultimately, this trial aims to find more effective treatments for anti-NMDAR encephalitis, paving the way for improved care for individuals facing this condition. Looking ahead, these advancements in clinical trials offer hope for developing better treatments and understanding AE, potentially leading to breakthroughs in managing and preventing the disease in the future.

Additionally, while the current trial focuses on anti-NMDAR encephalitis, the insights gained from understanding the mechanisms of action and treatment response could potentially apply to other types of AE as well. While the immediate beneficiaries of this trial are individuals with anti-NMDAR encephalitis, the broader implications may extend to those with different forms of AE in the future, offering hope for improved treatment options and outcomes across various autoimmune encephalitis conditions.

Receiving a diagnosis of any kind can be overwhelming. In cases like autoimmune encephalitis (AE) where the diagnostic process is often long and complicated, finally getting an answer can bring a sense of relief. At the same time, coming to terms with new information about your body and your health might be unsettling and full of uncertainty. What happens next? What should you know? How can you best advocate for yourself?

In this post, we will explore 7 questions you can ask while beginning the process of navigating an AE diagnosis. While this list is certainly not exhaustive (and not medical advice), we hope it can be a resource as you and your loved ones begin to make sense of the barrage of new information that comes with an AE diagnosis. These questions can be helpful discussion points so you can head into your next appointment with an AE specialist feeling confident and empowered.

1. Can you explain why we have landed on a diagnosis of autoimmune encephalitis?

When settling on a diagnosis, clinicians often make use of a checklist of expected symptoms and test results called the diagnostic criteria. Having your doctor explain the diagnostic criteria for AE (Figure 1) can help you understand how your symptoms and recent test results relate to the bigger picture. It is one of the easiest and most helpful ways to make sense of a new AE diagnosis.

IAES Fig1 500x358 - Seven questions you can ask your doctor to help you navigate an autoimmune encephalitis diagnosis

Figure 1. The requirements for an AE diagnosis are seen in bold above. Notably, there are subtypes of AE that are “seronegative,” meaning that patients will not have AE-associated autoantibodies. The asterisk next to this diagnostic criteria indicates that, because of this seronegativity, not all patients with AE will satisfy the requirement. It’s important to recognize that while these diagnostic criteria represent the current consensus, they may change as researchers and clinicians continue to learn more about AE.1-3

It’s important to keep in mind that there are many subtypes of AE, each with their own assortment of symptoms and caveats for diagnosis. In other words, some of the symptoms and test results listed as part of the AE diagnostic criteria are more likely to occur in some subtypes of AE than others. For instance, patients with some subtypes of AE (like anti-NMDAR, anti-GABAB, or anti-LGI1) experience frequent, severe seizures, while patients with other AE subtypes will have no seizure activity.4 As another example, while most AE subtypes are defined by the antibodies causing inflammation in the brain, there are some subtypes of AE, called antibody-negative AE or “seronegative” AE, where patients have no detectable autoantibodies in their blood or cerebrospinal fluid (CSF) samples.5 All this to say, don’t be alarmed if there are symptoms present on the diagnostic criteria list that you’ve never experienced. Because of AE’s diverse presentation, understanding exactly which AE subtype you have is crucial for beginning to interpret the ins and outs of your particular diagnosis. It can also be tremendously helpful for filtering information if you’re wanting to read more about AE or AE research online as sometimes literature only applies to particular kinds of AE. You should also keep in mind that even people with the same AE diagnosis might present with drastically different symptoms, receive different treatments, and recover on totally different timelines.

2. Given my diagnosis, what is the best treatment available?

In some sense, the best treatment for AE is one you can start quickly and keep up with consistently. Research shows that, given the rapid onset of AE, early treatment is key for getting the body’s inflammation under control and achieving a good outcome.6-7 Specifically, early access to therapeutics plays an important role in both promoting complete recovery and decreasing long-term complications.7-8 With this in mind, in some cases, a doctor might advise that you begin treatment for AE before all the test results come in and you’re officially diagnosed.

There are a variety of different treatment options that aim to reduce inflammation and provide relief from the symptoms of AE. Oftentimes, treatment begins with first-line therapies, like steroids, plasma exchange (PLEX), or intravenous immune globulin (IVIG).2,6 If there is no meaningful response after 2-4 weeks of therapy, physicians often move to second-line therapeutics, like Rituximab or Cyclophosphamide.6 When meeting with an AE specialist, it’s important to understand which treatment you’ll be trying first as well as what the range of future treatment options might look like in your case. Like with most conditions, the treatment plan may vary depending on your AE diagnosis as well as any other health conditions you may have. Patients with paraneoplastic AE (AE triggered by a tumor present somewhere in the body), for example, generally require the tumor to be removed to achieve remission.7 Regardless of treatment specifics, it can be reassuring to know that there is a Plan B in place if Plan A isn’t going perfectly.

Importantly, new treatments for autoimmune conditions like AE are a hot area of research. Immunotherapy drugs, for example, are increasingly emerging as “third-line” therapy for AE patients whose symptoms are not resolved by traditional treatment options.9 So, while AE symptoms can be stubborn and unrelenting for some patients, there is hope to be found in the fact that new options continue to move through the drug-development pipeline.

3. What treatment side effects should I be aware of?

When agreeing to a particular treatment plan, it’s important to not just ask about treatment options, but also their potential side effects. Exactly which side effects to look out for depends entirely on which treatment you’re taking. But, whatever they are, you’ll probably feel most confident starting a particular medication or therapy if you know both the beneficial changes to anticipate and the symptoms or signs that might tag along for the ride. Some side effects are little, short-term nuisances you can push through in order to recover long-term. Others might be much harder to tolerate or signs that you might need to return to the doctor’s office. Explicitly asking your physician which side effects fall into which of these categories can help put your mind at ease.

4. Are there AE signs or symptoms I should look out for that would warrant a call to my doctor?

In addition to keeping track of treatment side effects, it’s important to have a clear sense of AE symptoms to look out for that might indicate treatment isn’t working and the condition is progressing. Asking your doctor to list reasons for concern can help you be proactive in monitoring your AE symptoms as they ebb and flow over the course of the treatment process. Knowing what to look out for can also help you distinguish any treatment side effects from AE symptoms. It might also be worth asking your doctor to clarify when AE symptoms warrant a call to your doctor’s office or a visit to the emergency room. Having a sense of what merits a mental note vs. immediate action will not only make a tremendous difference in your care, but also help you feel more confident and secure in your AE management skills.

5. Are there any clinical trials I should consider participating in?

All drugs that are available, either at the hospital or from your local pharmacy, have been carefully tested through the clinical trial process. However, you might have the opportunity to try new medications by participating in a clinical trial yourself. People choose to participate in clinical trials for a number of reasons. For one, these trials are a way to access the newest treatments coupled with additional care from physicians on the clinical trial team. Participating in a clinical trial is also an opportunity to help accelerate scientific research and the development of safer, more effective treatment options for your condition. For rarer conditions, like AE, participating in clinical trials can have an even larger impact since it can be much more difficult to recruit enough participants to fill and complete a successful clinical trial.10

While it is understandably a big decision to participate in the testing process for a new drug, it’s important to remember that clinical trials are closely supervised and heavily regulated.11-12 Before deciding to participate, you’re provided an “informed consent document” describing the study’s purpose, duration, required procedures, risks, and potential benefits. The potential risks and benefits depend largely on the specifics of the clinical trial (i.e., the drug involved and what phase of the clinical trial process you’d be participating in). However, in most cases and phases, clinical trials are organized such that participants receive at least the same care they otherwise would at their doctor’s office.11,13 Importantly, consenting to participate in the trial is not a contract. You are free to change your mind and withdraw at any time or refuse particular treatments and tests.

If you’re interested in considering a clinical trial, it’s a good idea to discuss the details with your AE specialist. They should be able to explain the nuances, know whether or not you qualify for a particular trial, and offer their opinion on whether participating is in your best interest. Often, AE clinical trials will focus on a new drug for a particular AE subtype, meaning you’d need a specific AE diagnosis to participate. It is also worth knowing that not all clinical trials involve testing new drugs (so-called “interventional trials”). Many, especially in the world of AE, are observational trials that track patients and their responses to existing treatments over time. You can learn more about the clinical trial process using these detailed guidelines from The National Institutes of Health, and explore a list of AE clinical trials here.

6. How will my condition be monitored moving forward?

Whether or not you choose to participate in a clinical trial, your AE journey will likely still involve a lot of visits to the clinic. One of the trickiest parts about AE is the long-term outpatient management required due to residual symptoms that some patients experience following their initial episode.6,14  While there is variation depending on the subtype of AE, it has been estimated that 10-20% of patients experience an AE relapse.7 In order to help AE patients achieve the highest possible level of functionality and reach complete remission, “maintenance therapy” is usually considered.7

Because of the diversity of AE subtypes and symptoms, identifying a single clinician with appropriate expertise can be a major obstacle. As such, AE patients often accumulate a team of clinicians, each tasked with managing a part of their long-term care. You might, for example, have follow-up appointments with a psychiatrist for psychiatric symptoms; a neurologist for seizures, movement disorders, or dysautonomia; a speech therapist; an occupational therapist; and so on. The specialists you see might also change over time. This is because, while in some cases the AE symptoms a patient experiences with relapses are the same ones they experienced with the condition’s onset, in others, relapses can present differently than the initial wave.14-15

All these clinicians should have access to your medical records and charts so they can read each other’s notes, thoughts, and observations. However, it can’t hurt to relay the big picture at each appointment to make sure both you and the doctor are up to date. You can find helpful tips for how to compile and maintain a record of your personal health information here on the IAES website.

7. What resources exist for both patient and caregiver support?

While your clinicians can help manage your physical and mental symptoms, an AE diagnosis can also have tremendous emotional and social impacts. In addition to managing new medications and other therapies, many patients with AE must learn to manage their expectations of what day-to-day life will look like for a while. While it can be difficult, it’s important to remember that you do not need to navigate your AE diagnosis alone.

In addition to support from friends and family, it can be especially helpful to find and connect with other AE patients and caregivers. Organizations such as the International Autoimmune Encephalitis Society (IAES) have compiled a list of resources (including apps). Asking your doctor if they have additional recommendations — either online or in your area — can increase the chances that you’re able to find the support that’s right for you. It’s important to have lots of options as the type and level of support you need can change over the course of your AE journey.

Dr. Know on Autoimmune Encephalitis

You have brains in your head, you most certainly do

100 billion neurons are there, give or take one or two.

One rainy day when the weather was shoddy,

My immune system rebelled and made a strange antibody.

As quick as a shot from my head to my toes, my thinking and feeling went haywire to ‘anything goes’.

My seeing, my walking, my talking, MY WORD,

what I heard, what I saw, what I thought was absurd!

That antibody doubled, it tri-multi-zooppled!

Making an army of friends ~ all uninvited~ who hitched rides on my neurons getting them over excited!

Zipping this way and that way around in my brain

those antibodies zapped me causing terrible pain.

My poor brain it was not feeling well. My poor brain felt insane and it started to swell!

To the Doctor I went (for my thinking was spent).

I got this test and that test and a Brain selfie too

As my Doctor, called another Doctor, who called another he knew.

They all came to see me, to try and figure out what was wrong in my head?

What was this fuss all about?

“Could it be something rare? Could it be something quite new?”

Came a voice from the doorway where all eyes suddenly flew.

It was Dr. Dalmau stopping in for a look

All the Doctors were quiet, as this man wrote the book.

“I agree when you say it is not meningitis, this patient has Autoimmune Encephalitis!

Thank you UCB for sponsoring all 2024 AE Awareness Month blogs.

Some of you may be aware that IAES is completely powered by a volunteer staff. Volunteers are either caregivers or patients who have walked this walk and come out on the other side. After experiencing the trauma, they harbored a strong desire to create change so no one else would have to go through the experience without the help and support they so desperately needed. Some volunteer “AE Warriors” (a term I came up with in 2014 to denote the difference between an encephalitis ‘survivor’ versus an AE patient who has a long ongoing battle), are still receiving treatment themselves. Caregiver volunteers are also currently navigating the journey of their AE Warrior who is often still battling the disease. The quality of our volunteers, many of whom have medical backgrounds and their personal experience with AE, is the ‘secret sauce’ to IAES’ success. 

I began my patient advocacy in 2014, a year and a half after becoming ill in 2013.  Back then if you did a Google search for autoimmune encephalitis, nothing came up. I was able to find information on encephalitis, but nothing on AE. I did find a new organization whose mission was to build an alliance with doctors to further research. That was great to see. However, they only listed symptoms, tests, and a single paragraph defining AE which, while it was something, didn’t help me. It was an information desert.

My search for help led me to online forums. I found groups of people, largely undiagnosed, suffering, with no compass or light to guide them. These were dark days. I learned that before AE was identified in a 2007 paper by Dr. Josep Dalmau, patients were legally committed due to being misdiagnosed as a psychiatric case. They eventually perished.  “Frightening”, doesn’t begin to cover the situation we were in. The book Brain on Fire was on the New York Times best-seller list and catapulted awareness of this strange disease. As awareness ticked up slowly in the medical community, a great deal of misinformation accompanied it. There were only three locations in the U.S.A. with doctors familiar with this. They were: The Mayo Clinic, UPENN, and John Hopkins. That was it.

When people in need come to IAES, they may connect via our international telephone line, website inquiry, or one of our social media platforms. Everyone’s inquiry is handled with care for the best possible outcome for all. Many cases have an ongoing need. These are directed to different areas of IAES where a volunteer with the expertise required is assigned a case. IAES handles cases all over the world. Doctors regularly contact us via our website to learn about diagnosis and treatment and connect with experts who can confer on their cases. IAES is responsible for countless accurate diagnoses worldwide that would have gone misdiagnosed.

Members of our community have learned the value of self-advocacy. One of our goals in our mission is to help others become strong self-advocates. Daily personal attention is given to over 7,000 individuals on Facebook alone. The educational evidence-based private support group is the only one of its kind in the worldwide community. There, questions and advocacy advice are given based on what research reports and the talented administrators with specialized expertise on a variety of topics. Tools and techniques that support the patient’s deficits while utilizing their strengths are unique to IAES and the reason members can grasp complex information in a short period. Education is power and builds confidence. Feeling in control when facing a disease like AE is key.

When people contact us, it doesn’t dawn on them that they are speaking to someone who was once in the same situation their loved one is currently in. The hope and wonder of that realization immediately changes their perspective. AE can be reversed. The patient will improve. Hope is real. As strong as we volunteers are in our endeavor to create change and improve the lives of the people we serve, we struggle with our lasting deficits. All of us have cognitive impairments. Yet, what we have accomplished and how we manage it all daily, is something to witness.

Last week I reached out to members of the Board of Directors to ask if they could watch the awareness video for this year’s awareness month. How many AE Warriors did it take to find any typos or mistakes? It took five. I won’t complain about redoing the video 3 different times to make all the corrections. They were not caught in one go-round. That’s how it is behind the scenes. It takes 3-4 times longer to get a simple thing done. The important thing is that we get it done and reach our goal.  I thought you might like to be a fly on the wall and get a behind-the-scenes look into a typical daily phone call between staff members. 

Have you ever wondered what a telephone conversation between our President/Founder, Tabitha Orth, and another member of our Board of Directors is like? Two AE Warriors with memory issues and other cognitive deficits. Here’s a sample of a portion of a typical daily conversation with Board Secretary and Support Services Coordinator, Mari Wagner Davis with Tabitha. Mari’s time zone is two hours ahead of Tabitha’s. Both women return calls from the “Bat Phone”. Oh. The Bat Phone is IAES’ International Line. The name was coined by Tabitha’s husband Jim because when it rings Tabitha would jump up to answer it and he called after her, “Quick, It’s the bat phone!”.  When the bat phone rings, someone needs help, and it is usually crisis-driven.

—–

A few minutes into a conversation:

Tab: OMG, brain glitch. Not braining well. Just woke up.

Mari: Have you had your coffee?

Tab: Nooo.

Mari: That’s okay. That’s okay. Take your time. Make your coffee.

Tab: Yes, and while I’m waiting for my brain to unfreeze, what do you think of the idea of that new program we were discussing starting as an…oh. What’s the word I want? It means ‘experimental’?

Mari: Investigational?

Tab: No.

Mari: Exploratory?

Tab: No, that is good, it’s close to the word I’m thinking of.

Mari: Trial?

Tab: Yes! Thank you! Trial. My coffee is done.

Mari: Oh, Good!

Tab: Does that sound good to you? Starting the program as a trial program and building out from there?

Mari: I agree. It does. I was calling to tell you about that phone call I handled yesterday. You know the friend of a mother back east?

Tab: Was that the one who needed to learn about available support services and a waiver for a Mom?

Mari: No, it was the ICU pediatric case. Waiver Mom Case is taken care of though.

Tab: Oh, good to hear. Well done. Got it. Yes, Pediatric ICU.

Mari: I helped them to arrange a consult with an expert. That happened. Spoke to Mom at length so I answered all her questions and she felt so much better. That one is all good and done.

Tab: Oh! Great. Perfect. I love it when things flow the way you train people to do things for us. I swear you have a gift for telling people exactly what to do and why, have them check back with you about their progress, and then they are pleased to death when you compliment them on the amazing job they have done. You have people jump through hoops and check in with you to ask, ‘How am I doing’? as they go. It cracks me up as much as I am grateful to work with you.

Mari: Thanks! It is hilarious. Are we meeting with those people about that clinical trial on Tuesday or Thursday?

Tab: I think Tuesday is the clinical trial and Thursday is the website guy. But we better check.

While I have you I wanted to update you on the Christmas Eve/Christmas Day Crisis Case. This coffee is so good, that my brain is clicking in. It had a happy ending but my gosh it was a bad one. Seizure disorder went off her meds and was having major seizures. An ambulance transported the patient to the ER. The seizures triggered psychosis and they were threatening to have her handcuffed by police and transported to a psych hospital because there was no room for her at the inn (hospital) on Christmas Eve. I’m not too fond of holidays, skeleton crews, and packed ERs. Holidays and health emergencies are a terrible combination.  It took a lot of work, more than it should have because of the holidays. She was admitted to neurology, and all is right with the world. I don’t know if that would have been the outcome if she hadn’t had a seizure right in the middle of the discussion with the attending. Lord, I was thankful for the timing of that seizure. Crazy to say you have an angel on your shoulder about getting a seizure when you need one, but that’s how it is sometimes. So, happy ending. No traumatic psych hold on Christmas. Geez.

Mari:  ERs and holidays are the worst. I’m glad it all worked out.  We are going to have a good year.

Tab: We are going to have a GREAT year! I’m excited.

Mari: So am I.

Tab: I know there was something else I needed to talk to you about, but I can’t think of it now.

Mari: That’s fine. You’ll think of it as soon as you get off the phone, so just call me back.

Tab: OK. I’ll be behind the scenes working on e-mail and the awareness video. I’ll keep an eye out for any messages.

Mari: Okay. I have a slew of requests to join the support group and will answer questions.

Tab: I saw how crazy busy your team was there.

Mari: We’ve connected with several of them, so that’s looking good. Amanda connected with several. But, yes very busy.

Tab: I’ll watch out for your welcome post, so I can say hi to everyone. See you online.

Mari: See you there. Bye.

Introduction

Sleep is critical. Each one of us with AE has experienced fatigue at one time or another during our AE journeys. We, also, know how important it is to pay attention to the fatigue and do our best to get adequate rest for optimum recovery. Sleep is crucial for our brains. Joseph has explained another reason or in another way just how critical sleep is for us to be able to operate on a day-to-day basis to our best ability! We hope you enjoy this as much as we have.

If you’ve ever stared at falling sand in an hourglass, you might have noticed that when it accumulates on the pile below, every so often it will trigger an avalanche. Most of the time the avalanches are tiny and quick, just involving the top sand rolling lower, but sometimes the weight of the sand overcomes friction of the pile and a large chunk of sand fractures off and slides lower. It turns out that this seemingly simple sand pile is a mathematically interesting system that exhibits a trait called self-organizing criticality.1 The term ‘criticality’1,2 in this case refers to the fact the sand pile is constantly balancing at a critical transition point between stability (the sand pile building up), and chaos (sand avalanches triggering).  Notably, criticality doesn’t just apply to sand, it also may be an important part of how your brain works,2,3,4,5 and new research shows that sleep might be very important for maintaining this property!6

The edge of chaos

The idea that the brain, with its billions of neurons, operates at the edge of chaos might sound crazy at first, but it turns out that operating on this knife’s edge of criticality allows a system to process information at optimum efficiency.3,4,5,6 And since the brain needs to perform so many tasks, computations, and behaviors, it also needs to organize and activate its systems in an efficient manner.

Like avalanches on the sand pile, the firing of neurons throughout the brain seems to follow the mathematical criteria for criticality. That is, small numbers of neurons fire more frequently in mini avalanches of activity, but the larger the number of neurons that fire together, the more rare those neural avalanches are. For those interested, this is called a power law.3,4,5 In this way, the brain maintains balance between too few neurons firing, and too many at once, both of which may prevent the brain from functioning well.

In a related way, the brain must also maintain balance between order and chaos. If neurons fire too chaotically it results in a sub-critical state, and it is harder for the brain to process information, like when a person is under the influence of certain drugs or anesthetics.6 But if neurons fire in perfect order across the brain in a super-critical state, you can end up with an epileptic seizure.By operating in a critical state at the transition point between order and chaos, the brain processes information efficiently to deal with an ever-changing environment.

Admittedly, neuroscientists don’t all agree that the brain meets the definition for criticality, but the field is growing due to a steady trickle of evidence and a dedicated field of researchers. But still, what does all this mean for you? What does it mean for your brain to be at criticality, and could you even feel when it’s not? As it turns out, one of the reasons you need to sleep at night may be to maintain this criticality.

Sleep is critical

As you go about your day and the refreshing effects of a good night’s sleep wash away, you may feel like your brain is slipping further from an optimal state. In a recent paper, neuroscientists tested whether your brain moves increasingly farther away from criticality during the day, and if sleep can help restore this critical state for the next day.7

To do this, the neuroscientists recorded from many neurons in the brains of rats while they were awake and asleep. The team then measured mathematical aspects of criticality to compare the rats’ awake brains to their sleeping brains. They found that while their brains’ ‘closeness to criticality’ changed from moment to moment, in general their brains were farther from criticality the longer they were awake.7 Likewise, their brains were closer to criticality during sleep and closest just before they woke up after long durations of sleep. In other words, the longer the rats were awake, the further their brains were from criticality, while sleep reset their brains to a critical state.

While the authors of this study did not investigate exactly how sleeping moves the brain closer to a critical state, their findings present a provocative new view of the central function of sleep and why it is so important to maintaining brain health and function. Ultimately, this represents another piece of evidence suggesting that criticality is a core operating principle of how the brain works – just something to remember the next time you find yourself exhausted at the end of a workday feeling like you need to take a nap.

Introduction from the IAES Blog Team:

A diagnosis of Autoimmune Encephalitis can be devastating and overwhelming. It is difficult for patients, family members, caregivers, and medical teams. Watching a loved one suffer can be excrutiating. Being a parent of a suffering child is a level of mental pain that no one ever wishes to encounter. We share with you a beautiful poem written by Laura Zendejas that speaks to the heartbreak a loving Mother feels for her sick child.

I was happy before you came

I was worry free

I knew my child was safe and healthy

Then you came to be

You attacked her brain

You attacked me

You made me realize I had no control

That you were the all mighty

I begged

I cried

I asked why

Still I have no answers

Still I search today

Now that you have left my child

Why do I still feel this way?

Why do I still feel you near?

You attacked her brain and you set her free….

So why are you still attacking me?

Introduction

Our brains are what make us human – consciousness, emotion, and memory all come from a tapestry of over 100 trillion connections. When this intricate network is bombarded by misguided immune cells, as in the case of autoimmune encephalitis, the brain can no longer carry out some of its most important functions. One such function that is often prominently affected is memory.1,2 Memory is a central aspect of our daily lives, allowing us to recall cherished moments, learn from our experiences, and navigate the world. However, for individuals battling autoimmune encephalitis, memory can become a complex and challenging puzzle. In this blog post, we will describe the memory difficulties patients face when living with autoimmune encephalitis (AE).

What is memory?

Memory is a fundamental cognitive function that enables individuals to absorb, store, and recall information and experiences. It plays a crucial role in shaping our perception of the world and our ability to learn, make decisions, and navigate daily life. There are different types of memory that work together to enable us to learn, adapt, and navigate the complexities of life. Broadly, it can be helpful to think of grouping different types of memory by where they are in the brain because the brain organizes its functions into different locations. For example, the hippocampus is the main brain structure that helps record information and start the formation of memories.3 In addition, it is also important to consider the kind of information being stored and how long it is stored for (Figure 1). Here, we break down a few types of memory that are relevant to patients living with AE:

Sensory Memory: Sensory memory4 is responsible for briefly holding information from our sensory organs, such as vision and hearing. This short-lived memory lasts for a fraction of a second and is composed of all the information we get from our senses before our brain filters out the unimportant parts. It typically relies on parts of the brain that receive direct information from the sensory organs, such as the eyes and ears.

Short-Term Memory: Short-term memory4 is the next shortest type of memory, lasting for a few seconds to minutes. When you solve a quick math equation in your head or remember mid-conversation what someone just told you, you’re using your short-term memory.6 Short-term memory relies largely on communication between two parts of the brain called the prefrontal cortex and hippocampus.

Long-Term Memory (LTM): Long-term memory4 is exactly what it sounds like – the kind of memory that helps us remember things for long periods of time. It has an almost unlimited capacity and can last for a lifetime. Long-term memory includes our ability to remember personal experiences, facts, skills, and habits. Our ability to form these memories relies on the hippocampus and another part of the brain called the frontotemporal lobes, but where exactly long-term memory is stored is still unclear.

Procedural Memory: Procedural memory4 is a special type of long-term memory often mistakenly called “muscle memory” (because memory comes from the brain, of course!) that allows us to ride a bicycle, type on a keyboard, or tie our shoelaces with little conscious effort. Procedural memory does not depend on the hippocampus or prefrontal cortex. Instead, it tends to be formed and stored in the brain areas involved in planning motions, such as the cerebellum and the motor cortex.

Because different types of memory rely on different parts of the brain, sometimes patients with damage to only some parts of the brain can have deficits in only one type of memory, while the other types of memory are preserved.

Another concept that is central to most types of memory is the idea that brain cells, which are called neurons, can change the strength of their connections. Connections between neurons are called synapses, which are tiny gaps between the cells bridged by chemical and electrical signals.5 A bunch of neurons working together can mirror an electrical circuit, and the more synapses in a circuit are activated, the tighter and more numerous these connections become. This concept is known as synaptic plasticity, and the ability to retrieve memories may be dependent on how strong certain connections are.6

Figure 1. Memories form in discrete steps over time and are associated with specific parts of the brain.

 

How does autoimmune encephalitis affect memory?

Over the course of many years and research studies, doctors and scientists have shown that AE causes changes in memory. Both short-term and long-term memory impairments can occur in patients with AE; however, procedural memory impairments do not usually occur in AE.1,7-9 For patients with AE, deficits in short term memory can take the form of confusion and attention challenges; whereas deficits in long term memory can take the form of difficulty remembering facts, struggles with planning/organizing, and loss of personal memories. Although many patients show significant improvement in their memory symptoms after treatment of AE, many patients can unfortunately continue to experience residual memory problems, even long after other symptoms of AE have gone away.10

As discussed in a prior IAES blog post, AE is divided into different types based on which brain protein is attacked by a patient’s immune system. People with some subtypes of AE are more likely to have certain memory challenges.11 For example, patients with LGI1 autoimmune encephalitis (patients who have antibodies against Leucine-rich Glioma Inactivated protein 1) tend to have the most severe memory deficits with a profound loss of memories about personal life events. In contrast, memory loss and confusion are less common in patients with GABAAR encephalitis (~27%) and GABABR encephalitis (~47%). The reason behind these differences may in part be due to the fact that some of these proteins are only present in specific parts of the brain, which, as we previously discussed, control specific types of memory. Additionally, these targeted proteins play different roles in the circuits of the brain and disruption of different parts may impair synaptic plasticity in various ways. Please see the table below for more details about the memory changes experienced in different types of AE.

antibodies - Memory and Autoimmune Encephalitis

Table 1. Different types of AE are associated with different memory challenges for patients. Adapted from Gibson et al. – Cognitive impact of neuronal antibodies: encephalitis and beyond (2020).

 

To understand more about how AE causes memory changes, scientists first worked with patients using magnetic resonance imaging (MRI) to look at changes in the physical structure of their brains.12 Even as early as 1968, scientists saw drastic changes in the temporal lobes of patients with AE, which is a large region of the brain that contains the hippocampus.13 Importantly, recent studies have directly demonstrated that most patients with autoimmune encephalitis have structural changes in the hippocampus, and those with more damage in the hippocampus have more severe challenges with memory.14  

In addition to large structural changes, the microscopic science behind how AE causes memory loss has been explored in animal studies, which are more manipulable models for scientists to determine how diseases work in an entire system.15,16 In one experiment, scientists injected mice with antibodies from human patients with AE. They then tested the mice for any memory changes. Mice that were given the AE-associated antibodies could not remember objects they had seen before and developed anxiety-like behaviors.15 Importantly, scientists also showed that antibodies targeting the Nmethyl-Daspartate (NMDA) glutamate receptor (as seen in patients with Anti-NMDAR encephalitis) reduced the number of these proteins at the connections between brain cells which in turn disrupted synaptic plasticity.16

As previously mentioned, synaptic plasticity refers to the dynamic strength of circuits in the brain which increases when more neurons are activated together. Since glutamate is the main activating signal of the brain, it may be that destruction of the glutamate signal in certain types of AE leads to impaired memory by changing the strength of connections in the brain.

Lastly, an exciting early development occurred when scientists discovered that injecting Ephrin-B2, a protein that helps in the development of connections in the brain, was able to prevent memory loss caused by anti-NMDA antibodies in mice.16,17 Based on these findings, Ephrin-B2 may one day become a potential treatment for memory loss in patients living with AE!

Conclusion

In conclusion, autoimmune encephalitis is a neurological disorder that can have a profound and lasting impact on memory. Memory deficits in autoimmune encephalitis are not only distressing for patients but can also pose challenges to their daily functioning and quality of life. A better understanding of the mechanisms underlying these memory impairments and the development of targeted treatments are crucial to improving outcomes for individuals affected by autoimmune encephalitis and their memory-related challenges.

 Research in this field is ongoing, and with continued advancements in science and treatment, we can piece back together the lives of those affected by autoimmune encephalitis, one memory at a time.

The Island of Misfit Toys

The Island of Misfit Toys

January 10, 2024 | By Tabitha Orth, IAES Co-Founder and President

Our son, Matthew is watching Rudolph the Red Nose Reindeer tonight. It triggered the memory of a wise, insightful observation he had given me several years ago when I was recovering from a brain injury caused by autoimmune encephalitis.

My executive functions had taken a long vacay. They were MIA.  I rarely did something right. My memory took the hardest hit, especially my short-term memory. I needed a lot of help. That said, I was still “ME”. I was just – making a lot of mistakes. Matthew put his arm around me and tucked me into his side. This is a rare action of giving comfort for Matthew which made its impact more deeply felt. He said, “Mom, you are just like one of the toys on the Island of the Misfit Toys.” Love, acceptance, compassion, and comfort washed over me at the beauty of his words. Reassuring me that although I am a ‘broken’ Mom, I am deeply loved and he will always accept, support, and help me.

Those of you who know my son, know how engaging, honest, and forthright a man he is. You also know how much his autism impacts his life. A visual learner, Matthew has learned language from movies and cartoons. Social graces and social norms on all sides of the spectrum are gleamed through family film entertainment. So much of his understanding of the world, nature, history, science, and the like comes from documentaries on a wide range of topics. He saw I was ‘Mom’ and his Mom had “a brain problem” is how he described it. He told me it wasn’t my fault I “got a brain problem”.  I had been broken and his love never wavered.

Being reminded of the Island of the Misfit toys, had me searching the internet to look it up. I came across this article, We Are All on the Island of Misfit Toys, and it transfixed me. Yes. The author has this right.

The Island of the Misfit Toys Is a scene from the Christmas classic Rudolph the Red Nose Reindeer. If you don’t remember the story, the Island of Misfit Toys is where we find a Jack-in-the-Box named Charlie, a spotted toy elephant, a water pistol that shoots jelly, and all of the other weird toys that nobody wants to play with. The ruler of the Island–a kindly flying lion named King Moonracer is like Santa Claus in reverse–every night except Christmas, he goes all over the world looking for weird and unloved toys. Then he brings them back to the island where they form a community of the unlovely, unloved, and un-played-with. Eventually, the Moonracer promises them, he will find a little boy or girl who wants nothing more than a Jack-in-the-Box named Charlie.

As the article below explains, the inhabitants of the Island of the Misfit toys are splotchity. Synonyms for “splotchity” might include “irregular,” “unpredictable,” “uneven,” or even “messy.” But none of these work as well as “splotchity.” 

The author goes on to explain that the opposite of splotchiness is uniformity: factory-produced items that all look alike, tract homes in a new subdivision, things that are perfect, uniform, balanced, symmetrical, and even. Such uniformity does not occur in nature; it is the product of human enterprise. Human beings equate beauty with uniformity and go to great lengths to eliminate splotchitiness.

If God stamps each person with a uniqueness that signals his love, then those who believe in a higher power have a responsibility, not merely to tolerate what makes people unique, but to glory in its divinity. We are unique, and therefore splotchity, in many different ways, all of them divine. We are all misfit toys—because that is what beautiful looks like to God.

Note:

The term executive function (EF) is an “umbrella term” which encompasses a range of cognitive, emotional and behavioural difficulties which often occur after injury to the frontal lobes of the brain. Impairment of executive functions is common after brain injury and has a profound effect on many aspects of everyday life. Planning, problem-solving, self-monitoring, organization, divided attention, shifting or mental flexibility, and initiation of behaviors are often included under the term executive functions.

Attention and working memory are also sometimes listed as executive functions. The development of executive functions (EFs) is considered to be important because they are necessary for purposeful, planned, organized behaviors such as goal setting and attainment. Most of us take these abilities for granted and we effortlessly perform extremely complex tasks all the time in our everyday lives. Brain injury, Brain damage or active autoimmune encephalitis are all reasons that an individual may have difficulty with executive functions.

The Calendar

The Calendar

December 27, 2023 | by Jeri Gore, Editor-in-Chief of the IAES Blog

Each year since I have had the honor of having this job as Editor-in-Chief for IAES we have created a calendar. This calendar can be used and shared by all administrators at IAES to note important information that may be coming due. We use it to note events such as seminar schedules, publication dates, anniversary dates of import, dates to have jobs and other projects completed, and anything any of us need to remember and/or have all of us keep in mind regarding what is coming up.

 Creating a general calendar is something I’ve done for my family for years. Before we could share our calendars across electronic or social media platforms, we had a family wall calendar. I have kept those calendars as keepsakes. When I look back through them, they serve as a journal of sorts. I have a wonderful husband, four sons, and pets, and am blessed with amazing family and friends. We used our yearly family calendar to mark everything, so each family member would know what was happening daily. Sometimes when I look back and peruse these calendars such as the year our twins were born, I have NO idea how my husband and I ever had time to address basic needs such as sleeping and eating.

In 2019 I was diagnosed with AE, one of our sons was married and we moved. The 2019 Gore family calendar is heavily peppered with wedding-related meetings, fun events, house-buying, moving-related appointments, doctor’s appointments, and hospital stays.  It was a year of big ups and big downs: celebrations and tears.  Some folks love to write in journals and some document via pictures and videos. I journaled, in a way, via our annual Gore family calendar. Although my intent was not always for that purpose, at some point our family calendar transformed into a living journal that detailed the story of our lives. I love to occasionally look through them recounting the memories.

2023 is quickly winding into 2024 which has turned my direction to actively creating the framework for the IAES 2024 calendar. I am starting to look towards what 2024 will bring IAES and AE research in general. The webinars and events that will encompass and fill February/AE Awareness month are some of the biggest names in the field of Autoimmune Encephalitis, a star-studded line-up.  The art show and annual awareness video. I wonder what new information will come out in 2024 that we can present to all of you on the IAES website, newsletters, and blogs?

As I approach the 5-year anniversary of my AE diagnosis and I have the honor to look back on the IAES calendars of the past few years I am amazed. In a word, all I can say is WOW! The amount of work IAES has accomplished is breathtaking. I am constantly in awe of the folks I get to call my IAES family, the work they accomplish and the lives they touch! The amount of research into AE, therapies for AE, awareness of AE, and clinical studies for AE and the rate that all of this has sped up is awe-inspiring. There is still a mighty long way to go for sure. We still have many mountains to climb regarding AE awareness, treatment options, and ongoing rehabilitative therapies. But, for all of us thousands of AE Warriors, caregivers, and clinicians, I believe our future is very bright.

I wish you all a happy healthy New Year! May your 2024 calendars be positive, and bright, and may the mountains you must climb this year be less difficult!

 The best is yet to come!

The 12 Daze of Christmas

The 12 Daze of Christmas

December 13, 2023 | by Jeri Gore, Editor-in-Chief of the IAES Blog; Sung by Barbara Layt Vujaklija 

Happy Holidays from the entire staff at IAES!

To all our members all over the world and in whatever manner you celebrate we send our love, we wish you happiness and good health in the coming year!

We hope you enjoy this song and video as much as I do! When I first heard it, I laughed so hard my stomach hurt. The Twelve Days of Christmas has always been a favorite Christmas song of mine and to hear Barbara’s AE spoof on the original is brilliant and fun! IAES first released this back in 2015 when IAES was in its infancy.  Barb, our very first volunteer, and Tabitha Orth, our founder and president, wrote the lyrics.  Barb sang. How she did it without laughing is beyond me, but I am glad she did because we can all enjoy her merry take on a fun song for years and years.

I thought it appropriate to publish this video/song at this time in honor of the season as well as the person singing. Barbara is retiring from her post at IAES after years and countless hours spent volunteering on behalf of every single one of us. We have all been touched by Barb or the programs she helped to start. As stated above, she was the very first volunteer even before IAES became an official nonprofit organization. All new members have been greeted by the folks she helped train through the membership committee which she began. She and her team have guided over six thousand inquiries for new membership and helped direct them to the people and programs that best benefit each individual. Barb started the IAES blog and The Herdnewsletter. Both publications are unprecedented in the AE community. As a trained nurse and AE Warrior, herself, Barb has helped countless members and their families throughout every aspect of their AE diagnoses and journey. Barb’s knowledge, sense of humor, ability to remain calm in a crisis, and positive/can-do attitude have helped IAES become the organization it is today and will be in the future.

When I took over the IAES blog three years ago and became editor-in-chief I had mighty big shoes to fill. I was nervous! Barb was patient, helped guide me in an area in which I had no experience and always made me feel as though it would all be ok. To say I admire, and respect Barb is a complete understatement. It is because of Barb and folks like her that many of us with AE and our caregivers have had the help and guidance we have needed, and AE has gotten to the point of awareness it is today.  I, for one, will be forever grateful.

We hope you enjoy this song/video and giggle as much as I did! Barb, thank you for all you have done and for giving us your time, patience, and your singing voice

Introduction

When a patient is admitted to the hospital with symptoms that suggest a diagnosis of autoimmune encephalitis (AE), doctors start ordering a dizzying array of lab tests and scans. Although AE is a disease of the brain, many of these tests, such as CT scans of the chest or ultrasounds of the pelvis, don’t seem to have much to do with the brain at all. The purpose of these scans is to search for a tumor that lies somewhere in the body. The reason why doctors conduct this search for a tumor is because some AE patients have a subtype of the disease, called paraneoplastic encephalitis, in which their disease is actually caused by a tumor outside of the brain. In this post we will shed some light on paraneoplastic encephalitis, why it occurs, and how its treatment compares to other types of AE.

What is paraneoplastic encephalitis?

As we explained in a previous post, paraneoplastic encephalitis is a type of AE caused by a tumor somewhere outside of the brain. The symptoms of paraneoplastic encephalitis, which could include seizures, memory loss, confusion, and dizziness, are often the first signs of an underlying cancer.1 For this reason, a patient who is suspected to have autoimmune encephalitis will often undergo scans of each organ in their body (colloquially called a “pan-scan”) to search for a possible cancer that may be responsible for the patient’s symptoms.

Some malignancies that are especially likely to trigger paraneoplastic encephalitis include cancers of the breast, ovaries, and lungs.2 But why would a tumor in one of these organs outside the brain cause the immune system to attack the brain? To understand why, we need to learn a bit about how the immune system responds to cancer.

How does the immune system respond to cancer?

Though it may be an unsettling thought, abnormal cells with the potential to become cancer are born in the body all the time. We tend not to be aware of this because most of the time the immune system successfully squashes these abnormal cells before they become a full-blown cancer. Many scientific experiments have proven how effectively the immune system monitors the body for these cancer cells. For example, when mice are genetically engineered to lack key immune cells, they become much more susceptible to developing tumors – implying that the removed immune cells were necessary to prevent tumor development.3 Because the immune system plays a crucial role in protecting the body from cancer, many cutting edge cancer treatments work by empowering the patient’s own immune system to kill their cancer cells.

The immune system prevents the growth of tumors by reacting to abnormal proteins that are a sign of cancer. Tumors tend to produce mutated proteins that are not found in the healthy body. Once an immune cell sniffs out one of these proteins it hasn’t seen before, it eats the protein and starts sending out alarm bells to other immune cells. These alarm signals tell one set of immune cells, called B cells, to start making antibodies that bind to this suspicious protein. Antibodies function like little flags that mark the cell with the mutated protein for destruction. Specifically, in the case of paraneoplastic AE, the initial alarm bells also activate another set of immune cells called cytotoxic T cells.4,5 The role of cytotoxic T cells is to expertly survey for cells that have been marked as harmful as potentially cancerous. Then, once they find these potentially dangerous cells, they release toxins that kill the cells (Figure 1).

immune system cancer - What is the connection between cancer and autoimmune encephalitis?

Figure 1. How the immune system responds to cancer. 1. A “first-line” immune cell chews up breast tumor cells, which contain proteins not normally found in breast cells. These proteins are represented as crabs. 2. The “first-line” immune cell realizes that it has eaten a cancer cell and so it sends signals that activate B and cytotoxic T cells. 3. Activated B cells produce antibodies which bind to the crab proteins. At the same time, activated cytotoxic T cells start to look for the cells that are tagged by the antibodies. 4. Antibodies bind to the crab protein in the breast tumor cells. Once the cytotoxic T cells find these tagged cells, they release toxins to kill the breast tumor cells. This figure was created using Biorender.com.

 

Why do some people get paraneoplastic encephalitis?

Sometimes, tumors produce suspicious proteins that look very similar to proteins also found in the brain. For example, some breast cancers can produce a protein that looks very similar to a protein inside of specific neurons in the cerebellum (a part of the brain important for balance and coordination).6 In this way, as the immune system prepares for battle against the breast cancer, sometimes the brain with it’s cancer look-alike cells can get caught in the crossfire. When an immune cell detects the breast cancer cells, it will chew up the proteins in those breast cancer cells, including the ones that look like cerebellum proteins. Because these cerebellum proteins were found inside a breast cancer cell, the immune cell thinks that they are harmful. Therefore, the immune cell will tell B cells to make antibodies targeting the cerebellum protein. At the same it will also tell cytotoxic T cells to kill all cells with the cerebellum protein. When these cytotoxic T cells try to find and kill more tumor cells, they may also try to kill healthy cells in the cerebellum that  make the protein.7

Figure 2. How the immune system responds to cancer causes paraneoplastic AE. 1. A “first-line” immune cell chews up breast tumor cells, which contain proteins not normally found in breast cells. These proteins are represented as crabs. 2. The “first-line” immune cell realizes that it has eaten a cancer cell and so it sends signals that activate B and cytotoxic T cells. 3. Activated B cells produce antibodies which bind to the crab proteins. At the same time, activated cytotoxic T cells start to look for the cells that are tagged by the antibodies. 4. Because the crab protein is normally found in healthy cerebellum cells, antibodies bind to the crab protein in the cerebellum. Once the cytotoxic T cells find tagged cerebellum cells, they release toxins to kill the cerebellum cells.

What is the difference between paraneoplastic and non-paraneoplastic AE?

In the case of paraneoplastic encephalitis, the immune system is trying to do its job correctly by killing tumor cells, and the harm that it does to healthy neurons is collateral damage.7 This is different than cases of non-paraneoplastic encephalitis, where the problem lies within the immune system itself. In non-paraneoplastic AE, the immune system mistakenly decides that proteins that are normally found on the outside of neurons are actually harmful.7 (See this previous IAES post for a more detailed explanation of antibodies against proteins on the inside vs. the outside of cells.) In both paraneoplastic and non-paraneoplastic autoimmune encephalitis, the patient’s immune system tells B cells to make antibodies that target a neuronal protein. These antibodies then bind to the target protein in neurons and cause the patient to experience symptoms. However, cases of paraneoplastic encephalitis tend to involve more permanent damage to the neurons and more severe and long-lasting symptoms than cases of non-paraneoplastic autoimmune encephalitis. This is because the tumor also activates cytotoxic T cells in addition to B cells. These cytotoxic T cells are responsible for the increased damage and more severe symptoms in paraneoplastic AE.9

How is paraneoplastic autoimmune encephalitis treated?

When treating paraneoplastic AE, doctors often use the same therapies that are used for non-paraneoplastic AE.10The majority of these treatments, such as plasma exchange, IVIg, and rituximab, are aimed at eliminating the antibodies that target the neuronal protein.10-12 (You can learn more about antibody-targeting treatments in this post.) For patients with non-paraneoplastic AE, once the antibodies are no longer bound to the neuronal proteins their symptoms often go away. But, unfortunately, in the case of paraneoplastic encephalitis, both antibody-producing B cells and cytotoxic T cells are activated.9 The cytotoxic T cells can unfortunately do more permanent damage to their neurons than the antibodies alone. Because of this, patients with paraneoplastic encephalitis tend to have poorer responses to treatment when compared to patients with non-paraneoplastic autoimmune encephalitis.13

When treating paraneoplastic encephalitis, it is very important to treat the underlying cause of the encephalitis: the cancer.13-14 When patients receive treatment for their cancer, either in the form of surgery to remove the cancer or chemotherapy drugs to shrink the cancer, they can sometimes see some improvement in their paraneoplastic encephalitis symptoms.13 When treating patients with paraneoplastic AE, doctors are often faced with a particular challenge: the immune system serves as both friend and foe. On one hand, the immune system is what is causing the patient’s paraneoplastic AE symptoms. While on the other hand, as discussed above, a strong immune system is important for keeping cancer at bay. As such, doctors often must carefully consider whether they want to give patients drugs that suppress the immune system, especially if the patient is actively undergoing treatment for their cancer.9

There are already a number of new therapies on the horizon for paraneoplastic AE that will hopefully improve the symptoms and long-term outcomes of this disorder. For example, understanding the role of cytotoxic T cells in paraneoplastic AE has led scientists to start to test treatments that directly target cytotoxic T cells.15 Conducting clinical trials in a relatively rare disorder like paraneoplastic AE can be especially challenging. But a growing awareness among physicians about paraneoplastic AE has led to an increased number of patients receiving a proper diagnosis for their neurologic symptoms. Clinical trials that enroll larger numbers of patients with paraneoplastic AE will hopefully hasten the development of more effective treatments.

5 Ways to Answer “How Can I Help”

5 Ways to Answer “How Can I Help”


November 22, 2023 |  By Michelle Seitzer of Caregiving Advice

A message from IAES Blog staff:

In the US, Thanksgiving Day and week are upon us. And we have much to be thankful for. For those within the AE community, we cannot thank all those that care for us, in any capacity, enough! As we round out Caregiver Awareness month and head into a holiday season of joy, peace, and grace, may we all continue to be aware and be thankful for all we have been given. 

Michelle Seitzer founder of Caregiving Advice has graciously offered to let us share her article regarding ways to help those that care for us the most. We hope you find this as informative as we have!

She offers wonderful tips, and many ways caregivers can be cared for!!!

——-

Want to help a caregiver whose life is busy, busy, busy? Here’s how!

During this week’s Coffee Chat—our brand new virtual support group that takes place Mondays at 11ET on Instagram Live—we talked about what kind of help is actually helpful for caregivers, and why it’s so hard to get it.

We first posted this article in February 2020, right before the world shut down. How times have changed since then! But the advice we shared here? It hasn’t changed at all. Caregivers still need help. Caregivers still want help. But caregivers get a little triggered by kind offers from well-meaning people—and here’s the main reason why.

Because it feels like more work.

When caregivers hear these age-old phrases—“How can I help?” or “Let me know if I can do anything!”—our initial internal reaction is STRESS. Because the thought of coming up with helpful tasks feels like extra work, and extra work is something no caregiver wants. We want someone to lighten our load, not add to it!

Now don’t misunderstand: We are generally thankful for the offers. We appreciate that you see our need for help and want to provide it. But we need you to make it a little easier for us. And sometimes, we just need a little more time to think about it! As caregivers, we need to say that. “Thanks for your offer, can I get back to you with some ideas? And can you check in with me in a week if I forget?”

So caregivers, next time someone asks you *THE QUESTION,* refer to these 5 simple suggestions. And if you’re reading this as a person who wants to help a caregiver, thank you for your willingness; we hope you find these ideas helpful!

#1: Bring us a meal.

An oldie but a goodie: make us a meal! Or make a couple of meals for me to stack in my freezer, or send gift cards for GrubHub, UberEATS, or our favorite local pizzeria. Planning meals is often the last thing we want to squeeze into our busy day, which leads to lots of unhealthy dinners like frozen pizzas—or even worse, skipping meals altogether.

#2: Come visit us.

Screen Shot 2021 07 14 at 9.37.57 AM - 5 Ways to Answer "How Can I Help"

Offer to sit with our caree for a few hours while I run errands. Don’t feel comfortable with that? Just stop by for a visit when I’m there (if we’re all up for visitors that day)! Caregiving can be extremely lonely, so it’s a huge help to see friendly faces and welcome visitors! It’s equally as refreshing to have someone take over so I can get a few items checked off my to-do list.

#3: Fill our (gas) tanks.

If you really want to do something of monetary value for us, a gas gift card is always appreciated! There’s a lot of driving involved in caregiving, and it adds up. And financial pressures add to our already heavy caregiving load.

#4: Bring us groceries (treats included).

Screen Shot 2021 07 14 at 9.35.30 AM - 5 Ways to Answer "How Can I Help"

With online shopping now available in almost all areas—and with a variety of pick-up, drive-up or delivery options—this is an easy way to help that makes a HUGE difference!

Think of how much work it is to grocery shop…

It starts with planning: thinking about meals and snacks, then assessing what you need, taking note of what you’ve run out of, and jotting it down.

Then you have to figure out when to go, and depending on your caregiving situation, this can be a logistical challenge. Who can stay with your caree, if they need supervision? Or do you bring the person along, which comes with its own challenges? Some caregivers opt to shop at night when a spouse, partner, or child can stay home with the person you care for—but that often means shopping on tired legs and with a weary mind.

Now that you’ve figured out when to go, you have to drive there, go inside, fill your cart, empty your cart on the belt, load the bags in your cart, bring them out to your car, load them in your car, drive home, bring the bags into the house, then put the groceries away.

And then, of course, make a list of the things you forgot, because that inevitably happens, right?!

When you break down all the steps, you realize how much work is involved—and why it would be SUCH a help for someone to step in on this necessary life activity. (It also makes the case for paying the nominal delivery fee for those services, if you ask me!)

#5: Update others for us.

Offer to update others when something big happens. This one is a little tricky in terms of privacy, but it can still be super helpful.

The key word here is “offer.” Never give updates on my caregiving life without checking with me first. But if you know something big just happened (new diagnosis, a fall, change of living situation or school depending on age, a death or similar big loss/change in the family, etc.), ask me if I could help with letting others know.

Who are those “others?” Those are the people who would love to hear the latest on my caree but don’t necessarily need to hear it from me directly—i.e. my pastor, neighbors, boss/coworkers, friends I haven’t talked to in a while, to name a few.

It’s emotionally exhausting to repeat the same information — especially bad news — over and over again, so having someone offer to take on that task provides a huge sense of relief.

 

And there you have it! Five simple ways to help a caregiver whose life is busy, busy, busy. Pass this on to others who are looking for ways they can help, and let us know if you’d add anything to this list by commenting below.

Caregiver’s guide to self care & avoiding caregiver burnout

Caregiver’s guide to self care & avoiding caregiver burnout


November 8, 2023 |  By the SingleCare Team; medically reviewed by Gerardo Sison, Pharm.D.

November is Caregiver Awareness month! The staff and members of IAES celebrate, love, depend on and, at times, could not get by without those that have cared for us! To say we appreciate you is an understatement. So, this month we celebrate ALL of you wholeheartedly!

Thank you all!

We are honored to share with you a wonderful article by The SingleCare Team and thank them for allowing us this opportunity!

Learn risk factors, signs of burnout, and how to reduce the danger of caregiver burnout

A caregiver is anyone who assumes a significant level of responsibility for another person. This could be a family member, friend, or home healthcare worker. Caregivers demonstrate selflessness, commitment, and duty every day. But they also take on emotional and physical burdens that can become overwhelming.

What is caregiver burnout?

Caregiver burnout is a state of total exhaustion brought about by the emotional, physical, and mental toll of assuming responsibility for another person’s needs.

How does caregiver burnout start?

In most cases, caregiver burnout begins with emotional exhaustion. The stress and burden of providing for someone’s critical needs can exhaust a person’s ability to cope. Emotions like anger, sadness, and fear can be harder to control than usual.

caregiver burnout 440x500 - Caregiver’s guide to self care & avoiding caregiver burnout

Physical exhaustion often follows. Caregiving often requires new physical demands and usually leads to a reduction in other physical activities like exercise. One person may feel lethargic because they no longer go on their morning walk. Another person may have sore muscles because they have to bathe and clothe someone else, or sleep somewhere unfamiliar.

The combination of emotional and physical exhaustion can lead to mental exhaustion. A caregiver may begin making simple mistakes like forgetting appointments or leaving a key ingredient out of a favorite recipe. Restful sleep may be difficult, and a caregiver may lack motivation for social interaction. This is when exhaustion has reached the burnout stage.

If caregiver burnout is not addressed, it can lead to caregiver depression—a dangerous situation for the caregiver and the person to whom they are giving care. Depression is often characterized by feelings of worthlessness, sadness, or irritation, which can sometimes lead to chronic negative thoughts of hurting themselves or others.

If you or a loved one is experiencing severe depression or suicidal thoughts and behaviors, seek help from a healthcare provider or emergency room immediately. You can also call the National Suicide Prevention Lifeline at 800-273-TALK (8255).

Why is caregiving so exhausting?

Caregiving is exhausting because of the time and energy it requires. When someone you love can’t entirely fend for themselves, you want to help them. But when you are preparing meals, sorting out their financial situation, or helping them use the bathroom, you are using up energy and hours normally devoted to your own well-being.

In the end, the exhaustion often comes from losing the ability to do things that you enjoy and that make you, you.

What are the risk factors of caregiver burnout?

Not all caregivers get caregiver burnout. But among those that do, researchers have identified certain risk factors that seem to make caregivers more likely to suffer from burnout. Not everyone who has these risk factors will experience burnout, and people who don’t have any of these factors may experience burnout anyway.

Still, it is worth reviewing these risk factors and being aware of any that apply to you.

  • Physically demanding tasks (i.e., lifting someone out of a bathtub)
  • Taking care of someone that has severe behavior problems (i.e., dementia), not only physical ones
  • Financial difficulties
  • Living with the person you’re caring for
  • Lacking friends or a support network
  • A high percentage of time or long duration spent as a caretaker
  • History of substance abuse

What are the signs of caregiver burnout?

Certain signs may indicate total exhaustion or caregiver burnout. If you are a caregiver or know someone who is a caregiver, look for the following signs.

warning signs burnoiut 436x500 - Caregiver’s guide to self care & avoiding caregiver burnout

  • Feeling overwhelmed
  • Feeling constantly worried
  • Not getting enough sleep, or sleeping too much
  • Gaining or losing weight
  • Feeling angry at the person you’re caring for
  • Feeling easily irritated
  • Avoiding friends and family
  • Feeling sad or hopeless
  • Having frequent body pains, such as headaches
  • Increasing the use of alcohol, drugs, or prescription medications
  • Getting sick more often

Caregivers experiencing any of these symptoms should speak to their doctor.

Measuring caregiver stress and burnout

The Zarit Burden Interview is the most widely used diagnostic tool for identifying caregiver burden.

To determine whether you are experiencing excessive caregiver stress, consider taking this Caregiver Health Self Assessment Questionnaire that was developed by the American Medical Association.

How to avoid caregiver burnout

You now have an understanding of what caregiver burnout is, how to recognize it, and who is most likely to get it. Here are 12 proven methods of avoiding burnout.

1. Make sure you get breaks for yourself

There’s no “pause button” for caretaking. Every caregiver may have felt the urge to simply walk away, but they understand that doing so could be catastrophic for the person who is relying on them. You don’t want to let it get to that point.

That’s why implementing breaks into your daily routine is so important. Short breaks can have a hugely positive impact on your mental outlook.

In some cases, the person you are taking care of can manage on their own for a few hours, so you can get away. Others may at least be able to entertain themselves safely while you are in another room.

If you are helping someone who needs constant supervision, you’ll have to be proactive about scheduling breaks. This could mean drafting a neighbor, friend, or family member to help periodically. Or it could mean hiring a home healthcare worker to stop in a few days per week.

We’ve already learned that a high percentage of time spent as a caregiver is a risk factor for burnout. Do everything you can to ensure you have time to yourself to relax and recharge. It’s the best thing for you and for the person you’re caring for.

2. Use tools that make sharing updates simpler

A primary caregiver isn’t only a healthcare worker, they’re a reporter, too. Close family and friends will expect updates on topics like symptoms, prognosis, how their medication is working, what the person is eating, and more.

Individual calls or emails are nice, but time-consuming. When a caregiver isn’t able to provide updates as often as they’d like, they can feel guilty about it which adds to their burden.

Tools like CaringBridge, PostHope, or MyLifeLine make communication easier. These sites let you post updates simultaneously—with controls to protect your loved one’s privacy.

A single update shared with everyone also reduces the risk of miscommunication. Everyone will have the same information, so they don’t feel left out.

3. Use online resources

Every caregiver should have a device with internet access. Critical advice and important resources can often be just a few clicks away.

One of many examples is Eldercare Locator. This free resource site, produced by the U.S. Department of Health and Human Services, has a clean, readable design and trustworthy links. In just a few clicks, you can connect with insurance, transportation, and home care resources.

Many other online resources for caregivers are worth consulting, such as online support groups and local home health organizations.

4. Join a support group

Participating in a support group is one of the best ways that a caregiver can use their limited free time. Caregiving can be isolating and frustrating. On the most basic level, a support group reminds caregivers that there are others facing the same challenges.

But on a deeper level, a support group can help provide guidance that’s based on experience. And a caregiver can feel the satisfaction and catharsis of helping others by sharing their successes and failures with other like-minded individuals.

Bonding over these shared experiences often leads to friendship. As supportive as family and friends can be, they can only sympathize with what you’re going through. A fellow caregiver can share the burden and support you, like a coworker or teammate.

5. Take a self-assessment test regularly

Caregiver burnout doesn’t happen all at once. Emotional, physical, and mental exhaustion accumulates over time.

You stand a better chance of avoiding burnout if you track benchmarks in your mental health. Taking a self-assessment test regularly (say, once a month) will give you a clearer view of how well you are coping.

Self-assessments ask basic questions about your feelings and your physical health. They shouldn’t take more than 10 to 15 minutes. We recommend the Caregiver Health Self Assessment Questionnaire, which was developed by the American Medical Association.

This small-time investment could save you the consequences of burnout.

6. Maintain positive relationships with other friends and family

When a loved one is going through a health crisis, everyone wants to help. Sometimes the best help is the simplest: Reaching out to a friend or family member.

Caregivers need a sense of normalcy that can often be obtained by going on a walk with a former coworker, having brunch with old friends, or enjoying a night at the bowling alley.

Friends and family may feel that they have to do extra, or they may feel hesitant about trying to contact you. Try to maintain a schedule with friends and family members, either by having a phone call every few months or arranging lunch meetups once a week.

7. Set boundaries

One of the biggest changes when you become a caregiver is making decisions for someone else. And the people who also love that person may not always agree with the decisions you make.

You can’t make everyone happy, and being second guessed adds to your burden. Family and friends who want to provide help may do so in a way that interrupts your routine.

So set clear boundaries about things like who should attend doctor visits, when people should visit, and the types of assistance you actually need.

8. Set health goals for yourself, including mental health

The emotional burden of caregiving can cause you to neglect your physical and mental health.

Positive behaviors like exercise and meditation become important when you are under emotional strain. They are an effective way to calm your racing thoughts.

Give yourself achievable goals for activities like these. Phone apps can help by providing daily reminders and preset programs that last 10 to 30 minutes.

9. Set realistic goals for your caregiving and ask for help when you need it

Too many caregiving situations start in crisis mode and stay there. That’s a sure path to caregiver burnout.

Early on, work with your doctor to identify a realistic level of caretaking. Think about your loved one’s current and future needs and whether you will be able to provide them.

For example, someone with a progressive, debilitating disease may be able to function normally now, but what happens when they need help getting in and out of the bathtub?

What types of care are you comfortable giving? Could you give shots, or monitor IV drips? What about driving to pick up medications or necessities like groceries with them in the car?

Think about what will go into caretaking in your unique situation, and set realistic goals for what you can do.

Overextending yourself can lead to burnout (or a dangerous situation) for the person you’re caring for.

10. Talk to a professional, including a therapist or social worker

Becoming a caregiver is a time of stress and even shock. These are times when talk therapy can be extremely comforting and critical to our ability to cope.

Family and friends can be a sounding board, but they also have a close relationship with the person you’re caring for. That makes it hard to honestly discuss feelings of shame, guilt, or anger—feelings that are common and valid.

Speaking to a third party gives you the freedom to express yourself, put certain feelings out into the open, and work on strategies for coping with them.

11. Be realistic about your loved one’s disease

Another reason to seek advice from a third party is to be able to honestly discuss your loved one’s path to recovery—or their lack of one.

For dementia patients, sadly, there is no cure. And doctors can’t say for sure how fast the disease will take hold.

Acceptance can be the hardest part of dealing with certain diseases. We want to believe our loved ones will beat the odds. Thinking realistically about what the future holds can help us balance our hopes with the practical requirements of home care.

12. Develop coping strategies that work for you

Every caregiving situation is different and so is every caregiver.

Some people may decide to take time for solitary walks before deciding that what they really want is to join a support group.

Coping on a daily basis can be a real challenge. Try to identify the stressful parts of your day and how you could alleviate that stress. Maybe you’d benefit from getting housekeeping help or a meal delivery service. It doesn’t have to be forever, but keeping your head above water for the health of you and the person you’re caring for has to be the top priority.

Self-care is part of caregiving

Caregiving can be a shock to the system. Our instinct is to help our loved one, no matter the cost to ourselves. But as the days, weeks, and months go by, we run out of energy.

The most important thing for caregivers to remember is this: Successful caregiving includes caring for yourself.

Introduction

The causes and risk factors for autoimmune encephalitis (AE) are as varied as its many symptoms and subtypes. Determining the cause of a case of AE is challenging because there are often several factors to consider. In most cases, doctors do not know the cause of AE, but in an increasing number of cases they do. Continued research toward understanding the causes of AE is important, because they can help doctors determine which patients are at risk and help researchers in their quest to develop better treatments. This post will discuss a few known causes and risk factors for AE with a special focus on the link between viral infections and AE.

What are the known causes and risk factors for AE?

When considering what may lead to a case of AE, it’s important to distinguish between causes and risk factors. Doctors consider something a cause of AE when they know that a particular change or process is responsible for triggering AE. Other factors that may put someone at higher risk of developing AE but don’t actually cause AE are considered risk factors1. For example, infection with SARS-COV-2 is the cause of COVID-19 while spending time indoors with someone who has COVID is a risk factor. You’re much more likely to develop COVID-19 if you expose yourself to people who are infectious, but the ultimate cause of your illness would be infection with SARS-COV-2.

When it comes to AE, one of the clearest known causes is a tumor, which applies to a subset of AE called paraneoplastic AE2. Patients with paraneoplastic AE have tumors in various parts of their body that abnormally produce components of brain cells. When the body’s immune system produces cells to attack the tumor, it sometimes creates cells that target these components. If those immune cells get to the brain, they can attack the brain’s own cells too2,3.

Most of what we know about what leads to AE involves risk factors. For example, genetic risk factors have been shown to have a clear link to some types of limbic encephalitis. Specifically, a certain genetic mutation is found in 90% of patients with anti-LGI1 encephalitis, the most common form of limbic encephalitis that is not caused by a tumor4,5. Genetic testing is not common for patients with AE because the results will not change how doctors treat the AE, and because many people will have this mutation but not develop AE. However, pinpointing genetic mutations can be important for researchers because it gives them a clear target for their research if they want to understand why some people develop AE while others do not. By understanding what effects the mutation has on regular bodily functions, they can understand why the mutation makes the patient more likely to have AE. They can then use this information to create treatments that counteract the effects of the mutation.

It is even trickier to understand the various environmental factors that can put someone at higher risk of developing AE. Like all risk factors, not everyone who is exposed will develop AE. Environmental risk factors are especially difficult to pinpoint for several reasons, including because the many possible risk factors make it difficult to narrow down the possibilities, doctors often rely on patients being able to report what they have been exposed to which isn’t always possible, and sometimes multiple environmental factors have to combine to have an effect. However, by sharing suspected risk factors and communicating with other doctors and scientists, sometimes doctors can identify new risk factors that help them make future diagnoses. One case in which this has been especially successful is in establishing a link between viral infection and AE.

What is the relationship between herpes simplex virus infection and AE?

One of the best understood links between viral infection and AE is the relationship between herpes simplex virus and anti-NMDAR AE6,7. When herpes simplex virus infects the brain it causes a condition called herpes simplex encephalitis (HSE), in which the brain swells, just as it does in AE. Because they both cause brain swelling, AE and HSE have many similar symptoms, including seizures, headaches, and behavioral changes8,9. Many people carry the virus that typically causes HSE (over 60% of people under the age of 50), but it very rarely leads to HSE10. When not properly treated, HSE has a high mortality rate, but with early detection it can be effectively treated with antivirals8.

For a while, doctors noticed that some patients with HSE had recurring or relapsing symptoms following treatment with antivirals. When they investigated further, they found that some of these patients had anti-NMDAR antibodies, indicating that their recurring symptoms were a result of anti-NMDAR AE6,7. In several cases they were also able to show that patients did not have anti-NMDAR antibodies until well after developing HSE, suggesting that HSE is what triggered the production of anti-NMDAR antibodies6,11. Now, doctors know that patients experiencing relapsing symptoms after HSE should be screened for anti-NMDAR AE so they can be treated with AE treatments instead of antivirals7.

But, as to be expected in the case of AE, the story gets a bit more complicated. Patients that previously had HSE who have relapsing symptoms don’t just have anti-NMDAR antibodies. They also have antibodies against several other components of healthy neurons7. It’s still not clear if only the anti-NMDAR antibodies are responsible for the relapsing symptoms, or if these cases are different from other cases of anti-NMDAR AE because patients have a diverse set of antibodies. For example, cases where patients with HSE were later diagnosed with anti-NMDAR AE show more widespread damage to their neurons than patients with cases of anti-NMDAR AE that were not attributed to HSE6. Some doctors think that HSE may be a more widespread trigger of autoimmunity against neurons beyond just the targets of anti-NMDAR antibodies7. Luckily, in a few documented cases, the treatments traditionally used for anti-NMDAR AE appear to work in treating HSE-induced anti-NMDAR AE as well7,11.

Is there a relationship between other viral infections and AE?

There are several other possible connections between viral infection and AE, although none are as clearly observed or widely accepted as the link between herpes simplex virus and anti-NDMAR AE. In some very rare cases, AE cases follow COVID-19 infection12. Other viruses that have been detected in patients with AE are varicella, Epstein-Barr, human herpes virus type 6, adenovirus, HIV, and hepatitis C7.

It’s important to note that in all these cases it is still unclear if a viral infection caused AE. All we can say is that these viruses were present in patients with AE. The reason we can be more certain of the connection between HSE and AE is because several studies have reported HSE that precedes detection of anti-NMDAR antibodies11. More studies on the viruses listed above could eventually prove a similarly strong link between any of these viruses and AE if one exists.

AE isn’t the only autoimmune brain disorder that can be triggered by viruses. Perhaps the best example is Pediatric Acute-onset Neuropsychiatric Syndrome, or PANS. Patients with PANS are children who develop autoimmunity after infection with a virus. Strep throat, caused by infection with the streptococcus virus, is one common cause of PANS13. While the symptoms of PANS and AE are similar, there are some important differences that distinguish the two conditions. Another example is the possible link between infection with the Epstein-Barr virus and the development of multiple sclerosis, another autoimmune disorder of the nervous system14. Though still controversial, some research even suggests that Alzheimer’s Disease may be triggered by a viral infection15.

Concluding Thoughts

AE is very rarely the result of a viral infection, and only certain kinds of viral infections have been linked to AE. That being said, understanding the cases where viral infection puts someone at risk for AE, as with herpes simplex encephalitis, is important, because it can help doctors make a faster diagnosis of this otherwise difficult to diagnose disease. As scientists continue to find compelling links between viral infection and brain disorders, research that improves our understanding of how this process works has the potential to improve our understanding and treatment of these challenging brain disorders.
