[EEG anomalies, sleep modification and developmental dysphasia ].

The relation between severe developmental dysphasia and paroxystical anomalies was analyzed in 52 children, mean age 9 years (group I) suffering from developmental dysphasia, compared to a control group of 20 children, mean age 8 years (group II). The children of both groups were selected excluding cases with a prior history of epilepsy or neurological disease, and all had a cerebral MRI in the normal range. In group I, using the Rapin and Allen classification, we distinguished: 14 children with a syntactic-lexical syndrome and 34 children with a syntactic-phonological syndrome. Two children had verbal agnosia and two others verbal dyspraxia. The analysis of repeated standard EEGs showed: normal recordings in all the group II children and paroxystical anomalies in six of the 52 group I children. Night ambulatory sleep recordings showed such anomalies in 18 of the 34 children with a syntactic-phonologic syndrome and in 6 of the 14 children with a syntactic-lexical syndrome, but in only two of the 20 children of the control group. Paroxysmal abnormalities predominated in light sleep (stages I + II) and slow wave sleep (stages III + IV), but were rare in REM sleep. The abnormalities were diffuse or localized over the left frontotemporal area. Children with developmental dysphasia also showed an inconstant nocturnal sleep pattern with a higher incidence of awakenings during sleep significantly different from our group control. The relations between dysphasias, Landau-Kleffner syndrome, paroxystical anomalies, and sleep disorders are discussed and the results of genetic research concerning such population suffering from language disorders analyzed.

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.
