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.
What is the cause or basis of ADHD? It is an impulse disorder with genetic components that results from imbalances of neurotransmitters.
If your child has ADHD, they may have low levels of a brain chemical called dopamine. That's part of a mix of their genes, environment, and brain function that experts believe may cause ADHD.
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.
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.
Stimulants are believed to work by increasing dopamine levels in the brain. Dopamine is a neurotransmitter associated with motivation, pleasure, attention, and movement. For many people with ADHD, stimulant medications boost concentration and focus while reducing hyperactive and impulsive behaviors.
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.
Some experts recommend that people with ADHD avoid these substances: Artificial colors, especially red and yellow. Food additives such as aspartame, MSG (monosodium glutamate), and nitrites.
The symptoms may peak in severity when the child is seven to eight years of age, after which they often begin to decline. By the adolescent years, the hyperactive symptoms may be less noticeable, although ADHD can continue to be present.
Answer: Using caffeine, either in a drink or in an over-the-counter preparation, is not recommended by medical experts as a treatment for ADHD. Although some studies have shown that caffeine may improve concentration in adults with ADHD, it is not as effective as medication.
The most popular ADHD medications among ADDitude readers include (in alphabetical order): Adderall XR (amphetamine) Concerta (methylphenidate) Dexedrine (amphetamine)
Alcohol is a depressant. That is why many people use it to relax. In the case of people afflicted with ADHD, many will use alcohol to calm down the hyperactivity.
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.
Research suggests that people with ADHD crave dopamine. Their brains don't release or produce enough dopamine on their own. This causes a lack of focus and motivation. People who take medication for ADHD, such as Ritalin and other stimulants, get a boost of dopamine which allows them to function and focus.
ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
Boys (13%) are more likely to be diagnosed with ADHD than girls (6%). Black, non-Hispanic children and White, non-Hispanic children are more often diagnosed with ADHD (12% and 10%, respectively), than Hispanic children (8%) or Asian, non-Hispanic children (3%).
Vitamin B & C
Finally, supplementing vitamins B and C can also help alleviate ADD and ADHD symptoms. Vitamin C, like zinc, iron, and magnesium, is used to produce neurotransmitters like dopamine. Additionally, vitamin B deficiency is linked to irritability and fatigue in children.
