According to research, the optimal treatment for ADHD is multimodal and involves more than one type of treatment option. In fact, the National Institute of Mental Health conducted an enormous study about ADHD treatment (and gave it an equally enormous name)—the Multimodal Treatment of Attention Deficit Hyperactivity Disorder Study, or MTA Study for short. The MTA Study found that medication alone was not enough to effectively treat ADHD, and the most successful treatments combined therapy and medication.
