Abstract

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is under-recognized in children and adults. It is characterized by prominent neurologic and psychiatric features at first onset. Autonomic manifestations are rarer in children than in adults. We report a 3-year-old male patient with rare manifestation of severe autonomic dysfunctions of the gastrointestinal system and atypical prodromal symptoms. The serum and CSF of the patient were positive for anti-NMDA receptor antibodies, and his electroencephalogram results showed an “extreme delta brush” pattern. The patient had completely recovered by the sixth-month assessment after receiving first-line immunomodulatory treatment. Thus, anti-NMDAR encephalitis should be considered in the differential diagnosis of children with mental status changes and widespread autonomic dysfunction, particularly if symptoms are accompanied by gastrointestinal dysmotility and anhidrosis.
