[Reversible cortical atrophy secondary to anti-NMDA receptor antibody encephalitis].

Introduction: Anti-N-methyl-D-aspartate (NMDA) receptor antibody encephalitis was initially described as a paraneoplastic syndrome associated to ovarian teratomas. Yet, an increasing number of reports are being published involving cases of young women and children with signs and symptoms of an autoimmune encephalopathy, in 40-50% of the cases secondary to a viral infection. Clinically, it is characterised by a progressive picture of psychiatric manifestations, convulsive seizures, dyskinesias and dysautonomias.
