[Anti-N-Methyl-D-aspartate receptor encephalitis (anti-NMDAR): a case report].

Anti-N-methyl-D-aspartate receptor encephalitis (anti-NMDAR) is an autoimmune disorder characterized by neuropsychiatric symptoms, hyperkinetic movements, and even central hypoventilation. Anti-NMDAR encephalitis is a recently described disease, but is already considered one of the most frequent etiologies of noninfectious encephalitis. We report the case of 16-year-old man in which it the presence of anti-NMDAR antibodies in the absence of a neoplasm was identified. Disease course and gradual recovery, as well as a brief review of the syndrome, is presented. To our knowledge this is the first proven case of anti-NMDAR encephalitis in Mexico.
