Abstract
BACKGROUND: To examine the impact of executive function disorders on health-related quality of life (QoL) in children with neurofibromatosis type 1 (NF1), we conducted a prospective single-center study among 40 children with NF1 aged 8-12 years (mean = 9.7, SD = 1.4) and their parents, comparing them with 56 healthy control children matched for age, sex, parental education level, and handedness. We collected children's self-reports and parents' proxy reports of QoL with the Kidscreen-52 questionnaire, and measured executive functions by combining seven performance-based tests and a daily life questionnaire completed by parents and teachers. RESULTS: Several QoL domains were significantly impaired in the children with NF1, compared with healthy controls, mainly according to their parents' reports (3 out of 9 scales; Cohen's d: 0.57-0.76), with particularly low scores in the social support and peers and school environment domains. Executive function difficulties (Cohen's d: 0.64-1.72) significantly predicted the impairment of QoL domains as perceived by the children or their parents, regardless of the indirect indicators of learning disabilities. CONCLUSIONS: Both performance-based executive function scores and behavioral ratings of executive functions in daily life by parents and teachers were associated with low QoL levels in the children with NF1. The school environment and social integration appear to be particularly affected and should therefore be targeted in the management of the disease.
