Clinical Trial Summary

Electrical status epilepticus during slow wave sleep is a condition in which the epileptic patient starts to develop neurocognitive deterioration, any type of seizures and continuous electrical activity in the EEG during non rapid eye movement sleep. It is an age related condition and will resolve spontaneously at around the age of puberty. However if left untreated or treatment is delayed, it may lead to permanent neurocognitive deterioration. Thus early diagnosis and treatment is essential in these children to preserve neurocognitive function.

Clinical Trial 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:

1. epilepsy with different seizure types,

2. neuropsychological regression, and

3. 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. ;
