Questionnaire-based assessment of behavioral problems in Japanese children with epilepsy.

Behavioral problems in Japanese children with epilepsy were investigated by means of a questionnaire for parents consisting of three checklists: the Child Behavior Checklist (CBCL)/4-18 Japanese Edition, the High-Functioning Autism Spectrum Screening Questionnaire (ASSQ), and the Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale-IV (ADHD-RS) for parents. The participants were the parents of 108 children aged 6-18 years with apparently normal intelligence. The CBCL indicated abnormal behavior in 10.5 to 35.6% of the children, and T scores on both the internalizing and externalizing scales had a significant positive relation with scores on the ASSQ and ADHD-RS. It was revealed through multivariate logistic regression analysis that the persistence of seizures was significantly related with abnormality on the externalizing scale of the CBCL (p=0.010, odds ratio: 3.48, 95% confidence interval: 1.34-9.02). Future studies are needed to determine whether seizure freedom improves behavior in children with epilepsy.
