More Data About Gifted People with ADHD
I recently came across a paper from Tom Brown that adds to the growing scientific literature about smart people with ADHD, which I blogged about last year (http://tinyurl.com/qckgatx). Dr. Brown's study measured executive functions in 157 ADHD adults with an intelligence quotient (IQ) in the top 9 percent of the population. The executive functions of the brain regulate cognitive processes in a manner that allows for the effecting planning and execution of behaviors. We know from many studies that both children and ADHD have deficits in executive functions which impair their ability to manage time and keep themselves organized. Dr. Brown extends that literature by showing that three out of four ADHD adults with high IQ scores were significantly impaired on tests of executive functioning. They had problems in many areas: working memory, processing speed, and auditory verbal working memory relative.
The lesson from this literature is clear. Smart people can have ADHD. Their high IQs will help them do better than the average person with ADHD, but they may not achieve their potential without appropriate diagnosis and treatment.
