Anti–Nmethyl-D-aspartate (NMDA) receptor encephalitis is a common, autoimmune cause of encephalitis in children. Clinical manifestations usually include abnormal behaviour, change in mental status, speech difficulties, seizures, movement disorders and autonomic dysfunction [29]. Cerebellar ataxia has been described as the initial symptom [30] and during the first months of the disease associated with the other clinical manifestations [31, 32].
