Management Strategies For Electrical Status Epilepticus During Sleep
Management Strategies for Electrical Status Epilepticus During Sleep
Study Overview
Detailed Description
Electrical status epilepticus in sleep (ESES), also known as continuous spikes and waves during slow sleep (CSWS), is an age related, self - limiting disorder characterized by:
- epilepsy with different seizure types,
- neuropsychological regression, and
- typical EEG pattern of continuous epileptiform activity during non-rapid eye movement sleep (NREM).
During wakefulness, the EEG shows focal/multifocal spikes that increase in frequency during the acute stage. During sleep, ESES appears and is characterized by (1) marked potentiation of epileptiform discharges during non-REM sleep, leading to (2) a (near)-continuous, bilateral, or occasionally lateralized slow spikes and waves, (3) and these spikes and waves occur "during a significant proportion" of the non-REM sleep with a threshold ranging from 25% to 85%
The exact incidence of CSWS is not known. In pediatric neurology clinics, a reported frequency of 0.2% of childhood epilepsies most probably underestimates the incidence of CSWS.
CSWS is a devastating syndrome, which requires prompt treatment, the efficacy of which is checked with regular intervals, e.g. three or six months. Although epilepsy resolves with time in most cases, many children are left with significant cognitive or language impairment. Longer duration of ESES appears to be the major predictor of poor outcome.
So, early recognition and effective therapy are necessary to improve long-term prognosis in this condition.
The goal of treatment is not only to control clinical seizures but also to improve neuropsychological functions and prevent potential cognitive deterioration. There was no agreement on best treatment, but potential candidates included high-dose benzodiazepines, valproate, levetiracetam, and corticosteroids.

Description
Inclusion Criteria:
- All epileptic patients above 2 years of age presenting with neuropsychological deterioration, seizures and ESES in NREM sleep. The degree of epileptic activity during sleep will be measured and expressed as a spike wave index (SWI), which is defined as the total duration of continuous epileptic activity relative to total slow sleep duration. SWI must be at least 25% or more.
Exclusion Criteria:
- Any epileptic patient not presenting with typical EEG findings and neurocognitive regression.
