Attention Deficit / Hyperactivity Disorder

The ADD Information Service defines Attention Deficit / Hyperactivity Disorder as follows: Attention-Deficit/Hyperactivity Disorder (AD/HD) is characterised by developmentally inappropriate impulsivity, attention, and in some cases, hyperactivity. AD/HD is a neurobiological disability that affects three-to-five percent of school-age children and approximately two-to-four percent of adults. Although individuals with AD/HD can be very successful in life, without identification and proper treatment AD/HD can have serious consequences, including school failure, depression, conduct disorder, failed relationships, and substance abuse. Early identification and treatment increase the likelihood of positive long-term outcomes.

There are three primary subtypes:
