Psychiatric events in epilepsy

SummaryPsychiatric events are thought to be more frequent in people with epileptic seizures than in the general population. However, inter-ictal psychiatric events attributable to epilepsy remain controversial. The aim of the present study was to evaluate the occurrence of psychiatric events in a population of fairly unselected patients with epilepsy and in the general population, and the correlation between psychiatric complaints and selected demographic and disease characteristics. The survey was part of a multicentre prospective cohort study of everyday life risks conducted in eight European countries and comparing referral children and adults with epilepsy referred to secondary/tertiary centers to age- and sex-matched non-epileptic controls. Nine hundred and fifty-one patients with epilepsy and 909 controls were studied. Each patient and his/her control received a diary to record any accident or illness, with severity, circumstances, causes, consequences, and (for the cases) the possible relation to a seizure. The follow-up period ranged between 1 and 2 years. Fifty-eight psychiatric events occurred in 25 patients (2.6%) and 88 in 19 controls (2.1%). Housewives (9.3%) and unemployed persons (4.1%) were mostly affected. No correlation was found between psychiatric events, demographic and disease characteristics.Our results suggest that people with epilepsy if unselected are not at higher risk for psychiatric disorders than the general population.
