Attention Deficit Hyperactivity Disorder or ADHD is a dysfunction of the brain. People diagnosed with ADHD will exhibit these symptoms; poor attention span, excessive impulsivity and hyperactivity. These symptoms will cause people with ADHD to have problems with organization, memory, concentration, sitting, and remaining silent. ADHD was first identified in 1902 by Professor Still. Professor Still was observing children who showed signs of someone diagnosed with ADHD. He noted that the children could not sit still for any length of time or remain silent. He believed that this “agitation” came from somewhere inside the brain. This theory was supported by Bradley. In 1937, Bradley discovered a psychostimulant amphetamine capable of reducing hyperactivity levels. ADHD is a common disorder, approximately 30-40% of children are affected by ADHD. Today's leading ADHD expert is Professor Russell Barkley. Barkley believes that the symptoms exhibited are just reactions. A simple explanation would be that when you touch something hot, you retract your hand, which is a thoughtless reaction. Barkley's theory is that people diagnosed with ADHD are simply reacting, they are not thinking or thinking as much as a person without ADHD. They just react to normal daily tasks and it's all based on their personality in their frontal lobes. ADHD does not directly affect a person's intelligence, meaning a person can have a high IQ and still have ADHD, but it affects your educational abilities, which can negatively affect your intelligence.

Ultimately, there are a wide variety of stimulants and non-stimulants available and used for ADHD treatment, but not as many antidepressants.
