Diagnosed cases of attention deficit hyperactivity disorder are on the rise. A Centers for Disease Control and Prevention study shows eleven-percent of children between the ages of four and 17 are diagnosed with A.D.H.D. That's a 16 percent increase since 2007 and a 53 percent jump over the last decade. While drugs like Adderall and Ritalin can help many children deal with symptoms, they can also lead to addiction, heightened anxiety and even psychotic disorders. The CDC is worried that many prescriptions are unnecessary and could lead to abuse.
