ADHD Brain: The Neurology of Inattention, Impulsivity, and Hyperactivity
What is Happening in the Brain of a Person with ADHD ?
eeg of adhd brainThe most recent models describing what is happening neurologically in the brains of people with Attention Deficit Disorder suggest that several areas of the brain may be affected by the disorder. They include: Each of these areas of the brain is associated with various functions of the brain. Above is a sample Q-EEGs of two Attention Deficit Disorder children compared to two non- ADD ADHD children. 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. “Lack of control” is pretty descriptive of Attention Deficit Disorder kids. Medications, EEG Biofeedback training, Attend Nutraceuticals, and some other interventions, seem to change this and normalize, at least temporarily.
Impulsivity, Hyperactivity, and Lack of Inhibition
The frontal lobes help us to pay attention to tasks, focus concentration, make good decisions, plan ahead, learn and remember what we have learned. The frontal lobes also help us to behave appropriately for a given situation. Emotional issues such as anger, frustration, and irritability that come on impulsively in some types of ADHD probably come from the pre-frontal cortex. 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. These inhibitory mechanisms of the cortex help us to “inhibit” our behaviors. If you are researching the topic of the NEUROLOGY OF ADHD these books would be good resources for you to get and read.
It has been said that 70% of the brain is there to inhibit the other 30% of the brain.
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. 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. A normally functioning limbic system would provide for normal emotional changes, normal levels of energy, normal sleep routines, and normal levels of coping with stress. A dysfunctional limbic system results in problems with those areas. 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.
Frontal Lobes and ADHD : Glutamate, Dopamine, Norepinephrine, and a2 Receptors
What is the relationship between dopamine, norepinephrine, and glutamate?
One-third of the neurotransmitters in the brain are glutamate, and brain research is now looking at the intricate relationships between glutamate, dopamine, and norepinephrine in the functioning of the pre-frontal cortex. Glutamine is the pre-curser of glutamate. Research is revealing that the glutamate network neurotransmissions from the pre-frontal cortex to other areas of the brain are enhanced by dopamine and norepinephrine. Too little dopamine or norepinephrine is a problem, and too much is a problem. And the importance of glutamate in PFC functioning is beginning to come to the forefront in research. 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. One leading researcher is Amy Arnsten, Ph.D., Arnsten Lab, Dept or Neurobiology at Yale University. According to its website, the Arnsten Lab “studies molecular influences on the higher cognitive functions of the prefrontal cortex (PFC), with the overarching goal of developing rational treatments for cognitive disorders and mental illness… Research has focused on how the catecholamines norepinephrine (NE) and dopamine (DA), powerfully and dynamically modulate PFC cognitive function and physiology through intracellular signaling mechanisms.” The lab helped Shire Pharmaceuticals in the development of Intuniv for ADHD treatment. The Arnsten Lab has been able show how the relationship between dopamine and norepinephrine and the ratios of dopamine to norepinephrine, can impact and improve cognitive functions such as focus, memory, and attention. Too much or too little of either neurotransmitter decrease cognitive functions, both in terms of the performance of brain cells, and in the real world. But when the ratios and relationships are just right, performance is improved. Their work, along with the work of many others, is often focused on the a2-receptor sites in the pre-frontal cortex. They have reported on the benefits of norepinephrine at these sites, and have also shown the benefits of stimulating these receptor sites with the medication guanfacine (intuniv) which increases glutamate production in the PFC. It appears that by doing this, guanfacine improves cognitive functioning in the pre-fronatl cortex. This is potentially exciting because Intuniv (guanfacine) is not a stimulant medication. But, speaking of stimulants, other research has shown that small doses of methylphenidate actually impact the effects of norepinephrine in the pre-frontal cortex more than it impacts the effects of dopamine in the PFC. This research has also shown that when the a2 receptors in the pre-fronatal cortex are blocked that the symptoms of ADHD can be created in a subject, including lack of self-control, impulsivity, and hyperactivity (Berridg et al, 2006)
Reticular Activating System and ADHD
Attention Deficit Disorder and the Reticular Activating System
The answer may be found with the Reticular Activating System.
The Attention Center
The Reticular Activating System is the attention center in the brain. It is the key to “turning on your brain,” and also seems to be the center of motivation. The Reticular Activating System is connected at its base to the spinal cord where it receives information projected directly from the ascending sensory tracts. The brain stem reticular formation runs all the way up to the mid-brain.
The Reticular Activating System is a very complex collection of neurons that serve as a point of convergence for signals from the external world and from interior environment. In other words, it is the part of your brain where the world outside of you, and your thoughts and feelings from “inside” of you, meet. This Reticular Activating System is very capable of generating dynamic effects on the activity of the cortex, including the frontal lobes, and the motor activity centers of the brain.
The Reticular Activating System and Learning
The Reticular Activating System plays a significant role in determining whether a person can learn and remember things well or not, on whether or not a person is impulsive or self-controlled, on whether or not a person has high or low motor activity levels, and on whether or not a person is highly motivated or bored easily.
The RAS is the center of balance for the other systems involved in learning, self-control or inhibition, and motivation. When functioning normally, it provides the neural connections that are needed for the processing and learning of information, and the ability to pay attention to the correct task. If the Reticular Activating System doesn’t excite the neurons of the cortex as much as it ought to, then we see the results of an under-aroused cortex, such as difficulty learning, poor memory, little self-control, and so on. In fact, if the Reticular Activating System failed to activate the cortex at all one would see a lack of consciousness or even coma. What would happen if the Reticular Activating System was too excited, and aroused the cortex or other systems of the brain too much? We would see individuals with excessive startle responses, hyper-vigilance, touching everything, talking too much, restless, and hyperactive. So the Reticular Activating System must be activated to normal levels for the rest of the brain to function as it should. What factors could cause the Reticular Activating System to be either over-activated or under-activated? According to Harvard Medical School, current research strongly suggests that Attention Deficit Disorder – ADHD is caused in part by a deficiency of norepinephrine in the ascending reticular activating system. It is thought that the stimulant medications, such as Ritalin, increase the levels of norepinephrine in that part of the brain, as well as increasing the levels and effects of norepinephrine and dopamine in the frontal lobes. This treatment strategy works well for the inattentive under-aroused ADHD kids, and somewhat well for the over-aroused impulsive-hyperactive ADHD kids. However, for the kids who have an over-aroused Reticular Activating System to begin with, the use of stimulants will often exacerbate the problems with temper, sleep, and hyper-vigilance or anxiety. For these individuals their physicians will often prescribe a norepinephrine antagonist such as Clonadine, or an antidepressant such as Prozac, which works to enhance the Serotonin driven inhibitory mechanisms of the brain.

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. Each of these areas of the brain is associated with various functions. There are several areas of the brain potentially impacted, and there are several possible “types” of ADHD. Daniel Amen, a medical doctor using SPECT scans as identified six different types of ADHD, each with its own set of problems, and each different from the other “types.” In our practice we used five different “types” of ADHD, identifying each “type” with a character from the Winnie the Pooh stories (Pooh is inattentive, Tigger is hyperactive, Eeyore is depressive, and so on). We discuss in greater detail in the different types of ADHD section. The frontal lobes help us to pay attention to tasks, focus concentration, make good decisions, plan ahead, learn and remember what we have learned, and behave appropriately for the situation. 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. They help us to “inhibit” our behaviors. It has been said that 70% of the brain is there to inhibit the other 30%. The limbic system is the base of our emotions and our highly vigilant look-out tower. If 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. A normally functioning limbic system would provide for normal emotional changes, normal levels of energy, normal sleep routines, and normal levels of coping with stress. A dysfunctional limbic system results in problems with those areas. The Attention Deficit Hyperactivity Disorder might affect one, two, or all three of these areas, resulting in several different “styles” or “profiles” of children (and adults) with ADD ADHD.

Impulsivity – Go and Stop in the ADHD Brain
New Research Offers Insight Into Cause Of Impulsivity in ADHD
We have often felt sorry for those impulsive children who blurt out the first thing that comes to their mind when asked a question, especially if they are about to get into trouble. As most parents know, that first thing that comes out as the answer is usually a lie. And then the child has to spend the rest of the hour covering up the lie, that both he and his parents know is a lie. This is a classic scene of a child with ADHD getting into trouble because of his impulsivity. As a remedy, we encourage parents to warn the child that they are about to be asked a very serious question, and that their honesty is absolutely required. And that the child is not to answer the question for 30 seconds after being asked, so that they can clearly think about what they want to answer and get it right the first time. This works. But it is not what this article is about…
Impulsivity in ADHD
Impulsivity in ADHD is seen in two ways: It seems that a person with impulsivity as a part of their ADHD has a normal ability to say “Go” at the neurological level, but their ability to say “No” or “Stop” comes just a fraction of a second slower. As a result, things are often done, or said, without much self-control practiced.
Vanderbilt Research on ADHD
There is some very interesting new research out of Vanderbilt University’s Center for Integrative and Cognitive Neuroscience that helps to explain impulsivity in ADHD. From their press release, here are the basics of the study: “We think of people who are impulsive as acting too quickly,” said Gordon Logan, one of the researchers. “Kids with ADHD are actually slower on the ‘go’ task than the control kids. It’s not that they go too quickly; they stop too slowly.” “The research provides new insights into how the brain controls movements, which helps explain the impulsivity of people with attention deficit and hyperactivity disorder,” according to study co-author Jeffrey Schall, E. Bronson Professor of Neuroscience. “It also shows how mathematical models can be used to discover how the brain produces thought and action.” Read about the new Vanderbilt Study on Impulsivity See our collection of ADHD Research articles, or read the articles below to learn more about the ADHD brain and the neurology of attention deficit hyperactivity disorder.
