AD/HD is one of the most common disorders of childhood and adolescence.
• Attention deficit/hyperactivity disorder, or AD/HD, is a biological, brain-based condition thought to be caused by an imbalance of some of the brain’s neurotransmitters, which are the substances used to signal between nerve cells.
• The condition is characterized by hyperactive or impulsive behaviors and attention-deficit problems that cannot be explained by any other psychiatric condition and are not in keeping with the child’s intellectual ability or stage of development.
