ADHD is associated with abnormally low levels of the neurotransmitters transmitting between the prefrontal cortical area and the basal ganglia i.e., dopamine and noradrenaline. Dopamine is closely associated with reward centers in the brain, and also interacts with other potent neurotransmitters to regulate mood.
ADHD brains have low levels of a neurotransmitter called norepinephrine. Norepinephrine is linked arm-in-arm with dopamine. Dopamine is the thing that helps control the brain's reward and pleasure center.
ADHD was the first disorder found to be the result of a deficiency of a specific neurotransmitter — in this case, norepinephrine — and the first disorder found to respond to medications to correct this underlying deficiency. Like all neurotransmitters, norepinephrine is synthesized within the brain.
ADHD neurotransmitters dopamine and norepineprine are found to be deficient in this mental disorder.
The onset of attention-deficit-hyperactivity-disorder (ADHD) in childhood is characterized by developmentally inappropriate levels of hyperactivity, impulsivity and inattention. A chronic deficit of serotonin (5-HT) at the synapse may trigger symptoms of ADHD.
As you know, one trademark of ADHD is low levels of the neurotransmitter dopamine — a chemical released by nerve cells into the brain. Due to this lack of dopamine, people with ADHD are "chemically wired" to seek more, says John Ratey, M.D., professor of psychiatry at Harvard Medical School in Boston.
Experts initially believed that ADHD occurs as a result of low levels of dopamine, but they have since realized that the relationship is a little more complicated. According to the Gulf Bend Center, people with ADHD may have a higher concentration of dopamine transporters in the brain.
Key aspects of the reward system are underactive in ADHD brains, making it difficult to derive reward from ordinary activities. These dopamine-deficient brains experience a surge of motivation after a high-stimulation behavior triggers a release of dopamine.
In terms of neurotransmitter function for those with ADHD, vitamin D supports dopamine levels, norepinephrine levels, and serotonin release. Vitamin D increases the production of Acetylcholine, an important neurotransmitter in maintaining focus and concentration.
Executive functions have other roles which affect how someone thinks. In people with ADHD, these executive dysfunctions impact thinking in numerous ways. People with ADHD don't really think faster than people without it, but it can sometimes seem like they do.
People with ADHD have at least one defective gene, the DRD2 gene that makes it difficult for neurons to respond to dopamine, the neurotransmitter that is involved in feelings of pleasure and the regulation of attention.
Sugar and other high carb foods boost dopamine levels in the brain, leading us to crave them more often when dopamine levels are low. Since children with ADHD have chronically low levels of dopamine, they are more likely than other children to crave and eat sugary or carbohydrate-heavy foods.
The brain's frontal lobes, which are involved in ADHD, continue to mature until we reach age 35. In practical terms, this means that people with ADHD can expect some lessening of their symptoms over time. Many will not match the emotional maturity of a 21-year-old until their late 30's.
Low levels of dopamine can make you feel tired, moody, unmotivated and many other symptoms. Treatments are available for many of the medical conditions linked to low dopamine levels.
Some of the common foods that can cause ADHD reactions include milk, chocolate, soy, wheat, eggs, beans, corn, tomatoes, grapes, and oranges. If you suspect a food sensitivity may be contributing to your child's ADHD symptoms, talk to your ADHD dietitian or doctor about trying an elimination diet.
By Dr. David Velkoff. Ring of Fire ADD is a type of ADD characterized by abnormally increased activity in multiple areas of the brain, which in individuals on qEEG brain mapping scans can appear as over activity or overstimulation.
Supplements and Vitamins for ADHD Focus
Vitamins — particularly zinc, iron, Vitamin C, Vitamin B, and magnesium — are critical to healthy brain function. Experts recommend that people should strive to eat well-balanced meals and maintain healthy levels of these key nutrients, experts say.
Some signs that you might be understimulated include: Lack of motivation. Physical hyperactivity. A sense of unease, making you feel "flat" or irritable.
Get stimulated: ADHD minds often feel understimulated which can lead to dropping boring tasks for more exciting ones. Add in a fidget spinner, soothing music, slime, exercise, a podcast or anything that helps you get going. It's perfectly ok to pair activities as long as it helps you move closer to your goal.
Zinc, Iron, and Magnesium for ADHD
Zinc synthesizes dopamine and augments the effects of methylphenidate2. Low levels of this mineral correlate with inattention. Iron is also necessary for making dopamine.
While alcohol may appear as a short-term solution to restlessness and anxiety often associated with ADHD, heavy consumption can intensify symptoms of ADHD and render some ADHD medications ineffective.
You can test for low dopamine levels by taking a Dopamine Blood Test. This test measures the dopamine level in your body responsible for some brain functions such as movement, memory, behavior and cognition, pleasurable reward, attention, sleep, mood, and learning.
