title: [Epilepsy and disorders of cortical development in children with congenital cytomegalovirus infection].
abstract: BACKGROUND
  Neuroimaging and experimental studies have related cytomegalovirus (CMV) to certain neuronal migration disorders.
  
  
  METHODS
  To define the electroclinical picture of children with epilepsy associated with disorders of cortical development (DCD) and congenital CMV infection, we conducted a clinical, electroencephalographic and neuroradiological study of 10 children with this condition.
  
  
  RESULTS
  Eighty per cent of them had dismorphic traits, or malformations outside CNS. All showed other neuroradiological signs (cerebral calcification, white matter damage, porencephaly). Six patients with bihemispheric DCD (agyria-pachigyria, 2; 'poligyria', 1; schizencephaly, 1; bilateral opercular DCD, 2) showed: Tetraparesis, severe or profound mental deficiency, early onset epilepsy (mean age at onset: 11 months) with spasms, tonic seizures, partial seizures, and multifocal paroxysms or unusual diffuse sharp Alfa-Beta EEG activity. One child developed Epilepsia Partialis Continua. Children with bilateral opercular DCD evolved to a continuous spike and wave (SW) electrical status during wakefulness and sleep, linked to a worsening of psychomotor derangement. Four patients with unilateral hemispheric DCD (pachigyric or 'poligyric') showed: Congenital hemiparesis, mild intellectual deficiency, motor seizures (orofacial, hemiclonic, generalized) beginning in the third year of live, atypical absences with focal phenomena, frequent focal rhythmic SW discharges during wakefulness, and continuous SW status during sleep (CSWS).
  
  
  CONCLUSIONS
  A wide spectrum of DCD due to congenital CMV infection is documented. Characteristic electroclinical pictures related to the extent and topographical distribution of the DCD are recognized, which may lead to an appropriate diagnosis and prognosis.
