Objective
To compare Executive Functioning (EF) profiles across several pediatric medical conditions and explored the influence of age of diagnosis and evaluation.
Methods
This was a retrospective, cross sectional study of 734 children ages 5-18 across five medical groups [brain tumor, leukemia (ALL), epilepsy (EPI), Neurofibromatosis Type 1 (NF1), and Ornithine Transcarbamylase Deficiency (OTC-D)], ADHD controls, and matched healthy controls. We compared groups across the subscales of a parent completed Behavior Rating Inventory of Executive Functioning (BRIEF) using MANOVA. Separate MANOVAs were conducted to look at age factors.
Results
The ADHD group differed from all other groups and had the highest level of reported EF problems. The NF1 and OTC-D groups differed significantly from the healthy comparison group for overall EF problems, while the EPI and cancer groups did not. Working Memory was the most elevated subscale across medical groups, followed by Plan/Organize. Children with medical disorders were two to four times as likely as healthy controls to have clinically significant problems in several EF domains. There was a main effect for age at diagnosis and age at evaluation..
Conclusions
A subset of children with medical disorders were found to have parent reported EF difficulties, with particular vulnerability noted in working memory and organizational/planning skills. This has relevance for the development of interventions that may be helpful across disorders. Children with particular diagnoses and earlier age of diagnosis and evaluation had greater reported EF problems.
