Anti-N-Methyl-D-Aspartate receptor (NMDAR) encephalitis is probably the most common paraneoplastic encephalitis. In children, seizures, behavioral disturbances and abnormal movements are the most frequent symptoms. Electroencephalogram is abnormal in most patients. We report a child with anti- NMDAR encephalitis presenting extreme delta brushes in the EEG. This new EEG feature is described in patients with anti-NMDAR encephalitis, mostly adults. The identification of this EEG pattern may guide to an early diagnosis and treatment of anti-NMDAR encephalitis.
