NMDAR-Antibody Encephalitis: A new clinical way to identify patients
The study found that patients with NMDAR-antibody encephalitis presented with a complex co-existing mix of mental state changes, most commonly a combination of mood, psychosis, behavioral, sleep and catatonia which are best described by mixing traditional psychiatric diagnoses. This pattern became more stable when focusing on the cases that had the most detailed descriptions, emphasizing the need for professionals to be detailed and clear when describing and reporting mental states.
These observations should encourage the accurate detection of this form of autoimmune encephalitis and differentiate it from other serious mental-health illnesses. In addition, also by contrast to primary psychiatric illnesses, NMDAR-antibody encephalitis often occurs over days and patients typically have seizures and a distinctive movement disorder. Taken together, this set of observations aims to identify this group of immune therapy-sensitive patients from within unselected psychiatric presentations.
Most Shared Podcast: Autoimmune Encephalitis The key to treating encephalitis is early detection and treatment. A child with encephalitis requires immediate hospitalization and close monitoring. Sometimes, depending on what doctors think the specific cause of the encephalitis is, certain medications can be used to fight infections that may cause it. In this podcast, Dr. Stuart Tomko, MD, Washington University pediatric neurologist at St. Louis Children’s Hospital, discusses Autoimmune Encephalitis and when to refer to a specialist.

Old doc, new disease: Anti-NMDA receptor encephalitis
Dr Casey Parker reflects on an intriguing presentation that made him ask: What else do I not know?
The story begins:”It turns out Paul’s mother was right.The first time I saw him, Paul seemed to have a post-viral malaise. A head cold that lingered, a low mood and lethargy.His second visit two weeks later, however, left me confused. Paul seemed odd. Mumbling, disorganized and suspicious. I was concerned. This looked like an emerging psychosis, but there was nothing firm enough upon which to act.Paul’s mum was also worried. She could sense that something was seriously awry in her son’s mind. So I did another examination, which also proved fruitless.Paul seemed completely normal in many ways, but not in others. He had been doing his engineering exams a just month ago, but he was now struggling to do simple maths.”
Immunoneuropsychiatry — novel perspectives on brain disorders
Abstract’s Key points
- At the interface of neurological and psychiatric disorders, immune processes are major factors in CNS health and disease; the immune system contributes to CNS homeostasis, resilience and brain reserve.
- Although a certain level of neuroimmune interplay is required for optimal brain functioning, chronic inflammation and latent infections can cause higher-order network disturbances, resulting in cognitive and behavioural impairment.
- Psychosocial stress correlates with inflammatory processes in the CNS.
- Immune dysregulation plays a role not only in classical autoimmune brain diseases such as multiple sclerosis and autoimmune encephalitis but also in psychiatric disorders such as schizophrenia, autism spectrum disorder, bipolar disorder and depression.
- Immune treatments are emerging as therapeutic options for subgroups of patients with brain disorders that are associated with an inflammatory phenotype.
- New diagnostic and therapeutic criteria are required to translate immunopathogenic findings into individualized treatment options for patients with neuropsychiatric disorders.
Episodic ataxia in CASPR2 autoimmunity
by: Mayo Clinic Researchers: A.Sebastian López Chiriboga, Sean Pittock
A 64-year-old man developed cognitive dysfunction and generalized seizures, followed by episodes of transient speech and gait disturbances lasting several minutes, occurring multiple times per day; the events were not associated with any triggers. Neurologic examination during one of his episodic symptoms (video 1) showed transient ataxic dysarthria. Testing for neural autoantibodies revealed evidence of voltage-gated potassium channel complex antibodies by radioimmunoprecipitation assay; CASPR2-IgG was positive in serum and CSF by cell-based assay. Brain MRI was normal; CSF analysis showed an elevated protein level at 101 mg/dL, but it was otherwise normal. Oncologic evaluation was negative. The cognitive symptoms improved; seizures and episodic ataxia resolved after 12 weeks of treatment with IV methylprednisolone. Episodic ataxia is a manifestation of CASPR2 autoimmunity;1 patients can have normal MRI, and immunotherapy is beneficial.
