Clinical outcome in an infant with anti-NMDA receptor encephalitis: case report and literature review.

Abstract

Anti N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disease that often presents with various neurological and neuropsychiatric symptoms. Although most reported cases occur in children, only a limited number of studies on children are available. The subject of this case report is an 8-month-old female who presented with fever, vomiting, and seizure. She was diagnosed with encephalitis and treated with acyclovir. After 21 days, she showed irritability, seizure, orolingual-facial dyskinesias, choreodystonic movements, hemiparesis, dysphagia, strabismus, lack of interest in light and objects. Clinical signs, neuroimaging findings, and serum analysis of anti-NMDAR antibodies confirmed the diagnosis of anti-NMDAR encephalitis. After the first line of treatment, she showed full recovery. We update the infants with anti-NMDAR encephalitis in the literature. Clinical outcomes suggest that patients with anti-NMDAR encephalitis are mostly poor in the infants, excluding our case. We propose that early and appropriate treatments are critical for timely diagnosis and rapid improvement.
