Summary: Purpose: ADHD is reported as a frequent comorbidity in pediatric epilepsy. We aimed to clarify the prevalence of ADHD, its neurological correlates and the role of ADHD in health‐related quality of life (HRQOL) in children with severe epilepsy. Method: Data from the ADHD Rating Scale‐IV (ADHD‐RS‐IV) from 203 children (mean age = 11.8, SD = 3.8) from a tertiary center serving children with severe epilepsy were reviewed. Results: Inattention was frequently elevated in the sample (40% vs. 18% for hyperactivity‐impulsivity). Age of onset, epilepsy duration, and seizure frequency were not related to severity of inattention or hyperactivity‐impulsivity. Over 60% of children met screening criteria for ADHD‐Inattentive subtype (ADHD‐I) or ADHD‐Combined Inattentive/Hyperactive‐Impulsive subtype (ADHD‐C). Compared to ADHD‐I, ADHD‐C was associated with earlier onset of seizures, generalized epilepsy, lower adaptive level, and in normally developing children, a higher degree of intractability compared to ADHD‐I. ADHD‐I was more prevalent in localization‐related epilepsy, and there was a trend for a higher use of AEDs with cognitive side effects in this group. ADHD was associated with poor HRQOL: children with ADHD‐I and ADHD‐C had a two‐ and four‐fold likelihood of low HRQOL, respectively, compared to non‐ADHD children. Conclusions: Children seen at tertiary care centers for severe epilepsy are at high risk for attention problems and ADHD, and ADHD is a significant predictor of poor HRQOL in epilepsy, particularly in the case of ADHD‐C. ADHD occurring in the context of severe epilepsy appears to be associated with specific neurological characteristics, which has implications for comorbidity models of ADHD and epilepsy.
