In this series of one hundred and twenty-eight adults with Down's syndrome nearly half (i.e. 42.2 per cent) developed a normal EEG. This would appear to bear out the findings of Gregoziades and Pampiglione (1966) that older children with this syndrome tended to have tracings similar to the normal child. The youngest age group of fifteen to twenty-four years developed a normal tracing in 38.9 per cent of cases. The most frequent abnormality was an excess of theta, in keeping with the suggestion of Godinova and Hirai and Izawa that this was due to immaturity. Neither the presence of congenital heart disease nor diabetes nor intercurrent illness appeared to have any effect on the development of seizures. Epilepsy developed at any time during adult life but, not surprisingly, the five cases developing it had shown sharp or paroxysmal activity previously. Two had suffered from fainting attacks. In one, the diagnosis was confirmed later by a typical grand mal seizure and the other by response to anticonvulsants. Neither suffered from congenital heart disease.

In a 7-year prospective follow-up of 104 children with enuresis in 32 cases (19 boys and 13 girls) coexistence of common migraine was found. Twenty-two children had various other seizure-like disorders, particularly tics, febrile convulsions, pavor nocturnus and fainting, and three had absence attacks. In 20 cases vasomotor disturbances and in 17 abnormal Schellong's test were found. The IQ was normal or high in all cases. Emotional disorders were observed in nearly half the cases. The water-salt test of Decourt was done in 9 cases and it was abnormal in 8 cases. At least two abnormal EEG records were obtained in 26 cases, and in 24 of them seizure activity was demonstrated in the EEG. In the period of follow-up disappearance or very marked improvement of enuresis occurred in all cases and migrainous attacks became less frequent and intense in 27 cases, while in 5 the severity of migraine increased. The author discusses the pathological mechanism of these disturbances calling attention to less good efficiency of the regulatory functions of the centrencephalic activating system and hypothalamus connected with biochemical and bioelectric immaturity.
