ADHD is Attention Deficit Hyperactivity Disorder. It is a mental disorder that approximately three to seven percent of children have. Those that are affected by this disorder are characterized by constant behavior, lots of activity and often thought of as being disobedient. Yet, it is not that the individual is being bad but more so that they cannot control their mental range. Instead of being able to concentrate on one element, they are likely to be thinking about several thus making it quite difficult to concentrate. This disorder is not just found in children. Many adults are diagnosed with it as well. In adults, it is classified as AADD, or Adult Attention Deficit Disorder. About 30 to 70 percent of all children diagnosed with ADHD will carry on with their disorder through adulthood. It is harder to detect in adults because they have learned to adequately handle the disorder. By learning to live with it and work around it, adults have less of a need for help. Yet, in many cases both children and adults will need medications to help focus attention. Symptoms of this disorder in children will be such things as inattentiveness, impulsive behavior and constant restlessness. These children have a hard time sitting still or concentrating on just one thing for a very long period of time. In adults, it is more difficult to diagnose. It can be seen in the inability to structure their lies and to plan their daily activities. It is often less of a problem for them to stay attentive and to stop restlessness simply because these are secondary problems to daily planning of tasks. ADHD is a disorder that can be treated but not cured. It can be lived with or medication may be necessary. Seeking the assistance of medical personnel is necessary in any case.
