SLD with and without ADHD: Comparison of cognitive profiles

Abstract

A quarter of children with Specific Learning Disorder (SLD) have a comorbid attention deficit hyperactivity disorder (ADHD), which impacts the testing of intelligence. ADHD is therefore treated before proceeding with the assessment of intelligence. It is expected that the treatment of ADHD will mitigate its effects on intelligence testing. Though this is frequently done in clinical practice, we could not find any study comparing IQ profiles of children having SLD with and without ADHD after treating ADHD to look for any changes between them. Therefore, we planned this study to compare the cognitive profiles of children having SLD with and without ADHD and describe any difference in their profiles. It was a retrospective cross-sectional study. We compared 695 children having SLD with treated ADHD to 721 children having SLD without ADHD on their WISC III profiles. We found that children having SLD with treated ADHD scored significantly lower on Digit Span and Coding. We suggest routine use of Cognitive Working Memory Training, peer tutoring, and task modifications in children having SLD with ADHD along with medicines and remedial education for better outcomes.
