This year, the American Academy of Neurology's Sports Concussion Conference in Indianapolis revealed their finding that sportsmen who have suffered from a concussion are more prone to the development of anxiety and depression, as compared to average sportsmen.
According to Dr Robert Davis Moore, the additive effects of both ADHD and concussion leads to increased risk of anxiety and depression. The researchers did a study on athletes and discovered that athletes with both ADHD and concussion had significantly higher scores on the anxiety and depression tests the control groups. Moore also noted that athletes with a history of concussion were evaluated six months or more after the concussion. Thus, the difference in scores may be pronounced if they had evaluated the athletes shortly after the concussion.
