Relationship between interictal psychopathology and the type of epilepsy. Results of a survey in general practice

Abstract

Psychiatric morbidity was assessed in a sample of 88 adult epileptic patients drawn from general practices in South London. Using the Clinical Interview Schedule, 48% emerged as psychiatric cases. When either total CIS score or caseness status was used for comparison, group differences were evident; patients with temporal lobe epilepsy and focal non-TLE did not differ, but each was significantly more impaired than those with primary generalised epilepsy. The groups also differed in their psychiatric symptom profiles. The results suggest that the increased prevalence of interictal psychopathology commonly associated with TLE may also be a feature of other forms of focal epilepsy.
