Attention deficit hyperactivity disorder (ADHD) is one of the most feared and misunderstood of all medical conditions. Despite over 200 scientific papers being published on this neurological condition every year, it remains stigmatised and controversial. Some doctors don't even believe it exists.
Attention-Deficit Hyperactivity Disorder (ADHD or AD/HD or ADD) is a neurobehavioral developmental disorder. It is primarily characterized by "the co-existence of attentional problems and hyperactivity, with each behavior occurring infrequently alone" and symptoms starting before seven years of age.
