Through the use of video EEG and continuous monitoring, five variants of the "classical"<unk>  pattern have been identified: #<unk>  with increased interhemispheric synchronization. Characterized by symmetric and synchronized activity, seen in patients with longstanding evolution, especially in those with West syndrome that changes to Lennox-Gastaut syndrome. # Asymmetric<unk> . Associated with a brain structural abnormality, and does not necessarily predict the affected hemisphere. #<unk>  with a consistent focus of abnormal discharge. #<unk>  with episodes of voltage attenuation. Commonly seen during nonrapid eye movement (NREM) sleep. When the episodes of voltage attenuation appear at the same time as an epileptic spasm does, they are called electrodecrements. #<unk>  with little spike or sharp activity. The "H" in PEHO syndrome stands for<unk> . Together with developmental regression and infantile spasms,<unk>  is one of the diagnostic criteria for West syndrome.
