Objective. To examine the profile of executive function (EF) performance in children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) as function of their subtypes and comorbid disorders. Methods. Two hundred and eighteen, 6-12 year old children clinically diagnosed with ADHD were characterised according to their clinical profile. Various EF domains were assessed while children were not on medication. General cognitive performance was assessed using Wechsler Intelligence Scale for Children. Results. 54.1% of children were diagnosed with combined subtype, 34.9% with inattentive subtype and 11% with hyperactive subtype. Significant age difference was found in ADHD subtype distribution and significant age and IQ difference was found in EF performance. After controlling for age and IQ no association was found between EF and ADHD subtypes or EF and comorbid disorders. Conclusion. These results indicate that age and IQ play an important role in cognitive task performance.
