Anti-leucine-rich Glioma-inactivated-1 Encephalitis with Faciobrachial Dystonic Seizures and Behavioral Problems: A Case Report.

Anti-Leucine-rich glioma-inactivated-1 encephalitis is a subtype of autoimmune encephalitis characterized by cognitive impairment, faciobrachial dystonic seizures, and behavioural changes. There is no reported case from Nepal. We report a case of a 54-year old male who presented with abnormal body movement, behavioural changes, rapid eye movement sleep behavioural changes, and cognitive decline. Investigations revealed magnetic resonance imaging findings of fluidattenuated inversion recovery intensity signal in bilateral temporal lobes with anti-leucine-rich glioma-inactivated-1 antibody in serum leading to diagnosis of anti-leucine-rich glioma-inactivated-1 encephalitis. He was treated with steroids and intravenous immunoglobulin. Timely diagnosis is vital to prevent complications and improve outcomes.
