One of the greatest disservices to children and adults with mental health issues is marginalizing those who need medication...ADHD is a biological, neurological, and genetic disorder. Michael Phelps has not "beat" his ADHD diagnosis...he and his mother, Debbie Phelps (who provided a lot of structure to Michael), would be the first people to tell you that. Intense exercise and rigid structure have helped him cope with his symptoms, but it does not eliminate them.
