[Unilateral status epilepticus during the neonatal period]

Twenty-one newborns displaying a strictly unilateral status epilepticus were studied. Three groups have been isolated according to the aetiology: neonatal anoxia (n = 5), postcardiac surgery (n = 8), cerebral hemispheric lesions confirmed by CT scan (n = 7). The authors relate in detail the clinical features and the EEG abnormalities, ictal and interictal in each group, and comment on their results. They show the importance of EEG in establishing or detecting a unilateral status epilepticus and in helping the aetiologic diagnosis.
