Abstract
The scientific status of attention deficit hyperactivity disorder (ADHD) is highly controversial. Much of the controversy hinges on whether ADHD is a biological disorder. Advocates of biological causation often argue that it has a genetic basis. Etiology of ADHD has implications for treatment options, which is also a source of controversy. Given the ongoing interest in establishing the genetic basis of ADHD, this article critically examines the claims of a genetic basis to ADHD. We conclude that although genes may have a role to play in the expression of ADHD behaviors, available evidence suggests that the effect size of a genetic contribution is likely to be small.Keywords
