Psychiatric disorder and cognitive function in children with epilepsy in Kerala, South India.

The cognitive and psychiatric associations of childhood epilepsy have not been studied in developing countries. Children with epilepsy were identified during a population-based epidemiological study of 1403 8- to 12-year-old children in Kerala, South India. They were compared with age-, sex- and social class-matched controls on measures of reading, vocabulary, non-verbal reasoning and school performance. In addition, psychiatric symptoms were measured using standard questionnaires and the presence or absence of psychiatric disorder was established by interview. Patients performed as well as controls on the non-verbal test, but performed worse on tests of vocabulary and reading, suggesting a specific disadvantage in the area of education. Psychiatric disorder was more prevalent in the children with epilepsy. It was concluded that epilepsy in the population studied is accompanied by a significant burden of cognitive and psychiatric disorders which need recognition and adequate service provision.
