[Clinico-electrophysiological examination of children with Martin-Bell syndrome].

Based on somatic, psychopathological and electroencephalographic examination of 26 boys aged 3-11.5 years with Martin-Bell syndrome it was found that the disease is characterized by noticeable polymorphism. Three types of the encephalograms and 3 clinical types of diseased children were distinguished. The first two types of the EEG accounting for 73.1% of cases in whose clinical picture the teta-rhythm appeared dominant may be of diagnostic importance. The majority of that group of children included those with ambidexterity and left-handedness. In the control group children, the EEG materially differed in 92.3% of cases. No correlation was found between the clinical groups and the EEG patterns.
