Attention Deficit Hyperactive Disorder or ADHD is a medical disorder involving abnormalities in brain function. Often, this disorder can be passed genetically through families from one generation to the next. The condition is generally diagnosed in childhood, however we now know that ADHD commonly continues into adulthood. Although the hyperactivity component usually subsides in adults, attention and concentration problems often persist. If not caught in childhood, adults often become suspicious they may have adult ADHD when their children is diagnosed, and they recognize the same set of symptoms in themselves.
