Introduction/Overview

Attention Deficit Hyperactivity Disorder (ADHD) or hyperkinetic disorder is a psychiatric disorder with a chronic neurobehavioral syndrome demonstrating signs of inattention, impulsivity, restlessness and hyperactivity. It is important to note that the term Attention Deficit Disorder is a condition without hyperactivity (1) & (2).

People suffering from ADHD develop antipathy, lack concentration, indecisiveness, and organizational skills as well as avoid positions of responsibility.

About 5% of children in the age group of 9 – 17 years and 2-4% of adult population are affected in the US with ADHD. Studies suggest “…that boys are affected approximately five times more often than girls.” (1)

About 30%-80% of affected children carry this disorder into adulthood.

Other related conditions such as learning disorders, restless legs syndrome, ophthalmic convergence insufficiency, depression, anxiety disorder, antisocial personality disorder, substance abuse disorder, conduct disorder, and obsessive-compulsive behavior are more likely to appear in people suffering from ADHD than in the general public.

Based on the symptoms, Attention Deficit Hyperactive Disorders are classified into three types which include:

Predominantly Inattentive Type:
