Abstract

The relationships between severe developmental dysphasias and epilepsy were analysed in 32 patients with congenital dysphasias. The mean age was 8 years 2 months; 19 of 32 had never had seizures; 9 had had occasional seizures; 4 were epileptic. Twenty-two of 32 had normal repeated standard EEGs, but 10 (2 of which never had seizures) showed epileptic interictal discharges. During prolonged EEG after sleep deprivation, epileptic abnormalities were observed in 13 of the 32 cases (4 of which never had seizures). The overall night sleep recordings showed epileptic abnormalities in 30 of the 32 cases (17 of which had never had seizures). The epileptic interictal abnormalities varied considerably in intensity and aspect in the same patient from one examination to another. Developmentally aphasic children show a higher incidence of abnormal EEG than expected, particularly during overall night recordings. In most cases, the physiopathology of the language disturbance might be identical to that in Landau-Kleffner syndrome.
