Early electro-clinical features may contribute to diagnosis of the anti-NMDA receptor encephalitis in children

Highlights • Abundant theta and alpha band rhythms in non-rapid eye movement (NREM) sleep represent a suggestive EEG pattern of anti-NMDA receptor encephalitis in pediatric patients. • Preserved background activity over at least one hemisphere in the awake state and in sleep were correlated with mil...

Description
Summary:Highlights • Abundant theta and alpha band rhythms in non-rapid eye movement (NREM) sleep represent a suggestive EEG pattern of anti-NMDA receptor encephalitis in pediatric patients. • Preserved background activity over at least one hemisphere in the awake state and in sleep were correlated with milder clinical expression. • The disruption of NMDA neurotransmission may lead to decrease of the slow waves component in the NREM sleep.
