[Anti-NR1 antibodies in anti-N-methyl-D-aspartate receptor encephalitis and schizophrenia]

Abstract

The recent discovery of anti-NMDA receptor antibodies and proof of their pathogenic effects in limbic encephalitides raised many questions among neuroscientist and physicians working in the field of schizophrenia. Indeed, this two conditions share several major clinical, pathophysiological or etiological aspects and some authors tend to consider some forms of schizophrenia as mild-encephalitis cases. Some studies have reported the presence of these antibodies in schizophrenic patient's sera without neurological symptoms. These findings suggest new therapeutic perspectives in some schizophrenic patients, despite a low seroprevalence and pathogenic effects that remain to be demonstrated.
