Electroencephalographic examination of 50 women with Turner's syndrome.

An EEG study has been made of 50 women with Turner's syndrome, 39 found outside institutions and 11 in institutions for the mentally retarded. We found paroxysmal EEG abnormalities in 23 per cent of the former and in 55 per cent of the latter. We found indications of occipital lobe defects in the mentally retarded Turner women.
