Attention deficit hyperactivity disorder as a risk factor for concussions in NCAA division-I athletes

Objective: Sports-related concussions are associated with both acute and long-term consequences. Past work has identified novel risk factors and modifiers for concussions, including mood and neuropsychiatric disorders. Attention Deficit Hyperactivity Disorder (ADHD) is a common neuropsychiatric disorder that may also contribute to concussion risk, although no study has examined this possibility. Methods: One hundred and thirty-nine NCAA Division-I athletes at Kent State University (KSU) self-reported a history of prior concussion and diagnostic history of ADHD as part of a larger concussion management programme at KSU. Results: ADHD was prevalent (10.1%) and 18.0% of the sample reported a prior history of at least one concussion injury. 50.4% of athletes with ADHD reported a history of at least one prior concussion vs 14.4% of athletes without ADHD, which represented a significant difference (p<0.01). Analyses showed that athletes with ADHD were more likely to report a past history of concussions than those without ADHD (F (1,133) = 4.31, p = 0.04). Conclusion: ADHD is prevalent in NCAA Division-I athletes and associated with history of past concussions. If replicated, these findings could have important implications in the prevention and management of concussions in athletes with ADHD.
