Attention deficit hyperactivity disorder (ADHD) is an important issue for the physician taking care of athletes since ADHD is common in the athletic population, and comorbid issues affect athletes of all ages. The health care provider taking care of athletes should be familiar with making the diagnosis of ADHD, the management of ADHD, and how treatment medications impact exercise and performance. In this statement, the term "Team Physician" is used in reference to all healthcare providers that take care of athletes. These providers should understand the side effects of medications, regulatory issues regarding stimulant medications, and indications for additional testing. This position statement is not intended to be a comprehensive review of ADHD, but rather a directed review of the core issues related to the athlete with ADHD.
