Attention-deficit/hyperactivity disorder (ADHD) is a condition characterized by a short attention span, hyperactivity and impulsive behavior. People with ADHD cannot concentrate for a long period of time, can be impatient and often will delay performing tasks.
Occurring in about one in 10 children, ADHD is among the most common developmental difficulties in this population. It is also two to three times more frequent in boys than in girls. Formerly called attention-deficit disorder (ADD), the name was changed to include one of the disorder’s characteristic symptoms, hyperactivity.
There is no known cause of ADHD, although studies have shown that it has a neurological basis and might be inherited. Risk factors for ADHD include a family member who has ADHD, premature birth, personal exposure to environmental toxins, drug or alcohol use or smoking by the mother, and exposure of the mother to environmental toxins.
