Abstract
Objective. To understand early educational and behavioral predicament in childhood “epilepsy only.”Methods. A multicenter, prospective, longitudinal study was conducted of 51 outpatient schoolchildren with newly diagnosed idiopathic or cryptogenic epilepsy and 48 sex-matched classmate control subjects. All children underwent neuropsychological assessment 3 times within the first year after diagnosis; parents and teachers completed behavior questionnaires, and patients’ parents were interviewed to inventory contextual adversity. Principal components analysis of cognition and behavior disclosed 6 major components that were related with the interview data (repeated measures analysis of variance).Results. Despite similar intelligence and educational background, significantly more patients (51%) than control subjects (27%) required special educational assistance. Patients obtained worse scores across components of cognition and behavior. Parents and teachers perceived patients to have more behavioral problems. Differences between groups existed at pretreatment baseline. Over time, notwithstanding stable percentages of poor scores in both groups, nonpersistence of poor scores was impressive (each time other children scored poorly in other domains). Rather than epilepsy characteristics, contextual adversities were significant risk factors.Conclusion. Already in the earliest stage of the illness, children with epilepsy are liable to vicissitudes in cognitive and behavioral functioning. Contextual variables are all-important.
