All of us sometimes have difficulty sitting still, paying attention, and controlling impulsive acts. But when these problems occur so often that they get in the way of day-to-day life, they may be signs of attention-deficit/hyperactivity disorder (ADHD). ADHD is common; on average, about 1 school-aged child in 20 has ADHD.
ADHD interferes with a child's ability to regulate activity level (hyperactivity), inhibit behaviour (impulsivity), and attend to the task at hand (inattention). It affects many areas of a child's life, including self-control of behaviour, school achievement, and development of social skills and positive relationships. It is very important to identify and treat ADHD early.
