SUMMARY

We report four children with epilepsy with "continuous spike-waves during slow wave sleep" (CSWSS). The main clinical features were partial motor seizures, mental retardation and motor deficit. The EEG findings were characterized by nearly continuous (>85%) diffuse slow spike and wave activity in two patients, and localized to one hemisphere in two other cases during non-REM sleep. The treatment was effective in improving the clinical seizures, but not the EEG pattern. We believe that this epileptic syndrome has been overlooked and routine sleep EEG studies on epileptic children may disclose more cases of CSWSS.

Key words:epilepsy with continuous spike-waves during slow wave sleep, EEG, sleep.


RESUMO

Relatamos quatro crianças epilépticas com "ponta-onda contínua durante o sono lento" (POCSL). Os principais achados clínicos foram crises parciais motoras,retardo mental e déficit motor. Os EEG se caracterizaram por complexos ponta-onda quase contínuos (>85%) difusos em dois pacientes e localizados em um hemisfério nos outros dois casos. O tratamento foi eficaz no controle das crises, mas não em relação ao EEG. Achamos que este quadro tem sido pouco relatado e estudos do sono em crianças epilépticas podem revelar mais casos de POCSL.

Palavras-chave: epilepsia com ponta-onda contínua do sono lento, EEG, sono.
