Psychiatric manifestations in temporal lobe epilepsy: a controlled study

Abstract

Psychiatric disorder was studied in 62 patients with temporal lobe epilepsy (study group) and 70 patients with grand mal epilepsy (control group), both diagnosed electroencephalographically. The two groups were similar as regards age, sex, socio-economic status, duration and frequency of fits, family history and premorbid personality. A significantly greater number of temporal lobe epileptics had emotional disturbances in childhood and psychiatric abnormalities at the time of study. Neuroses, schizophrenia and behaviour disorder occurred more commonly in the study group, while epileptic personality and confusional psychosis were seen more frequently in the controls. The findings of the study are discussed in the light of relevant literature.
