My brother was incorrectly diagnosed ADHD without any childhood symptoms, because of current severe anxiety. He was prescribed Concerta and has been taking it for about two years. I only recently found out, and there is truly no way that he has ADHD. Some other disorders, yes, not ADHD. I am concerned because he was medicated for this, and I believe that it is exacerbating other issues, such as anxiety and depression. Most of his anxiety and depression have legitimate sources from a series of traumatic events. I believe that the Concerta may be making it worse.
