Is ADHD a Disorder of Executive Functioning?


Is ADHD a Disorder of Executive Functioning?

Thought leaders in psychology such as Russell Barkley, Ph.D., and Thomas Brown, Ph.D. have identified ADHD as a disorder of executive functioning. Rather than focusing on the major symptoms of ADHD such as difficulty with sustained attention, not listening, poor organization, forgetfulness in daily activities, restlessness, excessive talking, difficulty awaiting turns, or being fidgety, these experts see executive-functioning deficits as the defining characteristics of ADHD. Interestingly, executive dysfunctions, or difficulty employing executive-functioning skills, are also telltale features of many other psychiatric diagnoses in children. For example, beyond ADHD, children who have learning disabilities display an array of executive dysfunctions that underlie many of their academic struggles.

Technically speaking, the Diagnostic and Statistical Manual-V (DSM-V), which lists all current psychiatric disorders, does not directly incorporate executive dysfunctions into formal psychiatric diagnoses but describes many of these executive skills as features of common psychiatric issues. And while not a formal part of the diagnosis, identifying an executive dysfunction is very helpful in developing educational and psychological interventions for individuals.

It is common for those who do not have a formal psychiatric diagnosis to experience difficulty with one or more executive functions. For example, kids and teens might describe themselves as struggling with organization skills or having difficulty regulating their anger. However, moderate difficulty with executive functions does not warrant a psychiatric diagnosis. Problems with executive functions such as planning, working memory, and time management in the classroom can lead to lowered academic performance. When youngsters display many executive dysfunctions, consideration of a formal diagnosis and obtaining a neuropsychological evaluation may be appropriate.
