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.
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.
Scientists have observed that levels of dopamine are different in people with ADHD than in those without ADHD. Some researchers believe this difference is because neurons in the brains and nervous systems of people with unmedicated ADHD have higher concentrations of proteins called dopamine transporters.
Ritalin works by increasing the amount of dopamine released in the striatum, a key region in the brain related to motivation, action and cognition.
High-risk activities — driving fast, motorcycle riding, and waterskiing — motivate ADHD brains to focus. Some extreme activities, like daring ski jumps, sky-diving, or taking fast-acting street drugs, elicit a dopamine spike, the brain's most intense reward.
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. The ADHD brain has impaired activity in four functional regions of the brain.
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.
Getting enough sleep, exercising, listening to music, meditating, and spending time in the sun can all boost dopamine levels. Overall, a balanced diet and lifestyle can go a long way in increasing your body's natural production of dopamine and helping your brain function at its best.
There is no reliable way to directly measure the levels of dopamine in a person's brain, but there are some indirect ways. Some blood tests measure the levels of neurotransmitters, such as dopamine. However, these do not represent the levels of neurotransmitters in the nervous system itself.
The exposure to stressful life events, and—more specifically—Childhood Trauma, has been shown to predict ADHD onset as well as persistence of the disorder into adulthood (Biederman et al. 1995; Friedrichs et al.
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.

These are just some of the many risky behaviors children and teens with ADHD may find hard to resist, and thus, can lead to potentially dangerous behaviors as adults. And there's a biological reason individuals with ADHD favor risky behaviors: “ADHD brains crave stimulation,” writes Ellen Littman, Ph. D.
ADHD burnout is often something a little deeper. It refers to the cycle of over-committing and overextending that leads to fatigue in people with ADHD. It involves taking on too many tasks and commitments, and then the subsequent exhaustion that happens when we're unable to fulfill all of our obligations.
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.
And people with ADHD, thanks to a lifetime of personal and professional disappointments, are prone to perfectionist tendencies that end up perpetuating an unhealthy cycle. They engage in all-or-nothing thinking: Nothing is good enough, or they are so overwhelmed with doing something perfectly that they do nothing.
Thayer's study shows that the ADHD group of children had larger and more frequent variations. Fathers with ADHD will pass this code discrepancy to offspring. Barkley explains that the heritability of ADHD runs around 80 percent. Genetics account for 80 percent of the components that define ADHD.
ADHD more common in offspring of mothers with genetic serotonin deficiencies. Summary: Children whose mothers are genetically predisposed to have impaired production of serotonin appear more likely to develop attention-deficit hyperactivity disorder later in life, according to a new report.
ADHD is not caused by bad parenting, too much sugar, or too many video games. It is a brain-based, biological disorder.
Having low levels of dopamine can make you less motivated and excited about things. It's linked to some mental illnesses including depression, schizophrenia and psychosis.
Dopamine plays an important role in numerous functions, including motivation, reward, learning, movement, memory, and more. Dopamine deficiency is linked to numerous ailments, including Parkinson's, schizophrenia, and addiction.
