ADHD is usually first diagnosed during the elementary school years. In some cases, symptoms continue into adolescence. A teenager with Attention Deficit/Hyperactivity Disorder has problems with paying attention and concentration and/or with hyperactive and impulsive behavior. Despite good intentions, a teenager may be unable to listen well, organize work, and follow directions. Cooperating in sports and games may be difficult. Acting before thinking can cause problems with parents, teachers, and friends. These teens may be restless, fidgety, and unable to sit still.
Attention Deficit/Hyperactivity Disorder occurs more commonly in boys and symptoms are always present before the age of twelve. Problems related to ADHD appear in multiple areas of a youngster’s life and can be very upsetting to the teen, his/her family, and people at school. Symptoms of ADHD frequently become less severe during the late teen years and in young adulthood.
