About Attention Deficit Hyperactivity Disorder (ADHD)
Attention Deficit/Hyperactivity Disorder (ADHD) consists of a set of behaviours that usually manifest themselves in early childhood. The symptoms in children with ADHD are unlike the normally rambunctious behaviour of their peers. If not addressed, these behaviours can cause trouble for them at home, at school, and in the community. There are three groups of children with ADHD: those classified as hyperactive-impulsive; those who are largely inattentive; and those who have a combination of both types of symptoms.
