**  What is Happening in the Brain of a Person with ADHD? **  Ø “The Attention Deficit Disorder children show excessive slow brainwave activity (theta and alpha ranges) compared to non- ADD ADHD activity. The slow brainwave activity indicates a **lack of control in the cortex** of the brain.” **  Impulsivity, Hyperactivity, and Lack of Inhibition   **  Ø “The **frontal lobes** help us to pay attention to tasks, focus concentration, make good decisions, plan ahead, learn and remember what we have learned.”  Ø “Emotional issues such as anger, frustration, and irritability that come on impulsively in some types of ADHD probably come from the pre-frontal cortex.”  Ø “The **inhibitory mechanisms of the cortex** keep us from being hyperactive, from saying things out of turn, and from getting mad at inappropriate times, for examples.”  Ø “ It has been said that 70% of the brain is there to inhibit the other 30% of the brain.”  Ø “  When the inhibitory mechanisms of the brain aren't working as efficiently as they ought, then we can see results of what are sometimes called **"dis-inhibition disorders"** such as impulsive behaviors, quick temper, poor decision making, hyperactivity, and so on.”  Ø “The **limbic system** is the base of our emotions and our highly vigilant look-out tower. If the limbic system is over-activated, a person might have wide mood swings, or quick temper outbursts. He might also be "over-aroused," quick to startle, touching everything around him, hyper-vigilant.’  Ø “Attention Deficit Disorder might affect one, two, or all three of these areas, resulting in [|several different "styles" or "profiles"]of children (and adults) with Attention Deficit Disorder.”  Ø “Neuro-science is beginning to move away from seeing ADHD as just a problem with dopamine and/or norepinephrine, and is moving toward a better understanding of the brain as a network, and a network of relationships such as the relationship between dopamine, norepinephrine, the glutamate exitatory neurotransmitters which are about 30-35% of all neurotransmitters in the brain, and their relationship to ADHD.”  ADHD Causes
 * "Some models that attempt to describe what is happening in the brains of people with Attention Deficit Hyperactivity Disorder suggest that several areas of the brain may be affected by the disorder. They include the frontal lobes, the inhibitory mechanisms of the cortex, the limbic system, and the reticular activating system."
