Sleep EEG and developmental dysphasia.
To determine the relation between developmental dysphasia and EEG anomalies during sleep, we compared 52 subjects with dysphasia with a control group of 20 children by using the ambulatory EEG method. Whereas 50% of the children with dysphasia experienced paroxysmal activity (PA), only two of the control group did. It is likely that paroxysmal abnormalities and language impairment are related to architectural dysplasia and neuron-migration disturbances. PA is frequent in subjects with receptive developmental dysphasia and may be the cause of language deterioration. When the occurrence of paroxysmal abnormalities during sleep is higher than 8% of total sleep time, we suggest the use of antiepileptic drugs.
