Clinical and Cognitive Features of Attention Deficit Hyperactivity Disorder with Intellectual Giftedness: A Systematic Review

ABSTRACTA systematic review was carried out on publications from the last 15 years that have studied the effect of intellectual giftedness, defined as IQ > 115, on the clinical and cognitive features of ADHD. Studies indicate that about 15% of people with high IQ meet ADHD criteria. IQ has shown no effect on the pharmacological treatment, and comorbidity does not differ from that of other children with ADHD. High IQ-ADHD, compared to average IQ-ADHD, tends to show less severity in cognitive and behavioral symptoms, as well as a better prognosis; however high IQ may mask ADHD symptoms delaying diagnosis and treatment.
