Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is a potentially lethal clinical entity that belongs to the group of antibody-mediated encephalitis against synaptic proteins. It shows IgG antibodies against the NR1 subunit of the NMDA receptor (NMDA-R), which have been associated with psychiatric and neurological symptoms that develop in stages in the course of the disease. The predominance of neuropsychiatric symptoms in the early stages of the disease results in an increased number of patients that search for psychiatric evaluation as their first contact with the health system. For this reason, it is vital for physicians to recognize this entity as an important differential diagnosis in their clinical practice because, despite the severity of this condition, more than 75 % of patients achieve a substantial recovery with appropriate and timely treatment. We present a review of the literature on this disease, with special emphasis on the neuropsychiatric aspects.
