Abstract
The findings are presented in 366 patients with seizures who were studied by computerised tomography of the cranium. The relative frequency of normal scans, cerebral tumours, atrophy and other pathological lesions is indicated. A more detailed analysis of the group of patients with atrophy was carried out. The frequency and severity of atrophy correlated significantly with age but not with length of seizure history. However, the more marked degrees of atrophy were found among patients with long-standing or poorly controlled epilepsy, an observation which has important implications with regard to the adequacy of seizure control in epileptic patients.
