Abstract

Objectives: The purpose of the study was to define various aspects of epilepsy in a population based sample of adults with a learning disability.

Method: A purpose-designed questionnaire was used to collect information on various aspects of epilepsy on 143 adults with a learning disability and epilepsy. Names of these subjects were collected from a hospital for learning disabled adults, specialist epilepsy clinics and social services department. Data was gathered from case notes and direct patient examination.

Results: Generalised tonic clonic seizure was the most common seizure type. Seventy-three per cent sustained a seizure within the previous 12 months of the study. Abnormal EEG findings including excessive slow background activities and epileptiform waves were documented in a high proportion of subjects with a learning disability and epilepsy.

Conclusions: Both resistant epilepsy and generalised tonic clonic seizures seem to be more frequent among the learning disabled population compared with the general population.
