1 ESES may be the result of a secondary bilateral synchrony
ESES may be the result of a secondary bilateral synchrony. The focal motor seizure is a common type of seizure, and focal epileptiform activity is usually seen during wakefulness and REM sleep. This EEG can sometimes simulate benign focal epilepsy syndrome such as epilepsy with centro-temporal spikes. The duration of ESES and the localization of focal epileptiform activity play major roles in cognitive dysfunction, suggesting that the clinical features in ESES result from a localized disruption of EEG activity caused by focal epileptic activity during slow sleep. Spike-wave activity less than 85% during NREM sleep was correlated with a decrease in cognitive impairment.139,140 Source: Epileptic Encephalopathy, Atlas of Pediatric EEG Citation: Laoprasert P.
