Presentation Title:

Autoimmune encephalitis with psychiatric onset: What every clinician should know

Abstract

Autoimmune encephalitis (AE) often begins with prominent psychiatric symptoms such as hallucinations, agitation, catatonia, or acute psychosis, frequently preceding seizures or focal neurological signs. These presentations can be mistaken for primary psychiatric disorders, especially when antibody testing is negative or not readily available. As a result, patients are commonly misdiagnosed, and immunotherapy is delayed.  This presentation aims to emphasize the importance of recognizing acute psychiatric symptoms as potential red flags for AE. To that end, we will review the current literature on the neuropsychiatric manifestations of AE.  The session will be illustrated by four real-world cases previously published by the author.  Psychiatrists, psychologists, and general physicians are often the first point of contact and therefore play a critical role in recognizing the possibility of AE. Improving awareness of these neuropsychiatric presentations can reduce diagnostic delays, facilitate timely treatment, and strengthen interdisciplinary collaboration between psychiatry and neurology.
