Objective: To examine the association between weaknesses in executive functions and attention-deficit/hyperactivity disorder (ADHD). Method: Empirical studies examining executive functions in
ADHD samples were reviewed, with particular attention to results of recent meta-analyses. Results: ADHD is associated with impaired performance on measures of response inhibition, working
memory, and other aspects of executive functions, yet data also suggest significant neuropsychological
variability within and across ADHD samples. Conclusion: ADHD may be best conceptualized
as a neuropsychologically heterogeneous condition. More work is needed to characterize this heterogeneity
and its clinical and pathophysiologic implications.
