AN INTRODUCTION TO ATTENTION DEFICIT HYPERACTIVITY DISORDER Attention Deficit Hyperactivity Disorder has many manifestations and there are more than five kinds of ADHD. It is a medical condition that is carried in the genes, resulting in certain disorders in the nervous system. The DSM-IV Diagnostic Manual reports that any single form or “type” of Attention Deficit Hyperactivity Disorder could be categorized under the diagnostic chapter of ADHD. This central list is then broken into ADHD Impulsive-Hyperactive Type, ADHD Inattentive Type, or ADHD Combined Type. Sometime ago, the words attention deficit disorder “without” or “with” hyperactivity were also generally used. Not only does the Attention Deficit Hyperactivity can take various forms, but also there could be so many combinations that different kids could show different symptoms. It generally happens that Attention Deficit Hyperactivity Disorder affects more than three or four parts of the brain. This causes many singular “profiles” or “styles” of children and sometimes even adults with ADHD or ADD. The various styles influence actions in the following four spheres: • Number one, inability to attend. • Number two, difficulties in Impulse Control. • Number three, problems with motor restlessness or hyperactivity. • Number four, a condition which is yet to be declared “officially” in the manuals of diagnosis, but should be – that condition is being bored quickly. To mention a few more crucial aspects of this condition: 1. This disorder is observable in the majority of circumstances, both in school and also home. If the child shows the symptoms only in his or her home, then possibilities like depression of the child, or deliberately being unruly with the parents, cannot be entirely ruled out. 2. Another thing is that the disorder could be noticed before the child crosses seven years of age. Because Attention deficit Hyperactivity Disorder is caused due to neurological problems, it could be either from an injury to the head, or could have been carried in the genes itself. The problem takes a firm grip and creates real adjustment issues with the increase in school activities and task. But by the age of seven the symptoms of Attention Deficit Disorder could be noticed with a little scrutiny.
