[Research progress on electroencephalogram characteristics of anti-N-methyl-D-aspartate receptor encephalitis].

Anti-N-methyl-d-aspartate (NMDA) receptor encephalitis is a kind of autoimmune disease aiming at NR1 subunit of NMDA receptor. In the early stage, functional damage is the main cause. Electroencephalogram (EEG) can reflect the abnormal brain function by recording the changes of EEG signals. The common EEG patterns of anti NMDA receptor encephalitis are slow wave abnormality, epileptic discharge, a large number of β activity, extreme delta brush, etc. Here we review the waveform characteristics, origin, pathogenesis and clinical value of EEG in patients with NMDA receptor encephalitis.
