That’s the preliminary conclusion of a study of 120 U.S. college athletes who suffered concussions. Forty had ADHD; 80 did not. Of those with ADHD, half were taking stimulant medications for the disorder. Concussion symptoms averaged 12 days for athletes with ADHD who were taking medication; 10 days for those with ADHD who were not on medication; and four days for those without ADHD.
Compared to injured athletes without ADHD, those with unmedicated ADHD had larger declines in thinking and learning skills days after their concussion and also when they returned to play. Researchers said athletes with ADHD who were taking stimulant medications responded more slowly at both of those times than those without ADHD on tests of visual motor speed.
