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.
