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.
Whats the science behind ADHD?
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.
What chemically ADHD?
Biological: ADHD is associated with the way certain neurotransmitters (chemicals in the brain that help control behavior) work, especially dopamine and norepinephrine, and this difference causes changes in two different attentional networks of the brain — the default network, associated with automatic attention and the …
What chemical in the brain causes ADHD?
Recent studies show that the brain chemical, dopamine, may play a role in ADHD. Dopamine is an important chemical that carries signals between nerves in the brain. It is linked to many functions, including movement, sleep, mood, attention, and learning.
What is happening in the brain with ADHD?
Brain development is also slower in people with ADHD. The neural pathways don’t connect and mature at the same rate, making it harder to pay attention and focus. This can impair executive function, which handles organization and routine tasks. ADHD impacts brain chemistry, too.
Is ADHD a lack of serotonin?
Serotonin is another neurotransmitter implicated in ADHD. It influences mood, social behavior, sleep, and memory. Low levels of serotonin may impair these important functions.
Can ADHD go away?
Many children (perhaps as many as half) will outgrow their symptoms but others do not, so ADHD can affect a person into adulthood.
Does ADHD get worse with age?
Hormonal changes can cause ADHD symptoms to worsen, making life even more difficult for women. For men and women, aging can also lead to cognitive changes.
What is the root cause of ADHD?
Genetics. 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 a child with ADHD are more likely to have ADHD themselves.
What happens if ADHD is left untreated?
Untreated ADHD in an adult can lead to significant problems with education, social and family situations and relationships, employment, self-esteem, and emotional health. It is never too late to recognize, diagnose, and treat ADHD and any other mental health condition that can commonly occur with it.
Why do ADHD brains crave sugar?
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 kids with ADHD have chronically low levels of dopamine, they are more likely than other kids to crave and eat sugary or carbohydrate-heavy foods.
Can a brain scan show ADHD?
Brain magnetic resonance imaging (MRI) can be used to identify people with attention-deficit/hyperactivity disorder (ADHD) from patients without the condition, according to a new study published in Radiology. Information from brain MRIs may also help to distinguish among subtypes of ADHD.
Are ADHD people smart?
People with ADHD aren’t smart
People with ADHD are often perceived to have low intelligence because they work differently than the rest of the population. But the truth is, many of these people are highly intelligent and creative; even more creative than their non-ADHD counterparts.

Do ADHD brains look different?
ADHD: Large imaging study confirms differences in several brain regions. The largest imaging study of its kind finds that people diagnosed with ADHD have altered brains. It identifies size differences in several brain regions and the brain overall, with the greatest differences seen in children rather than adults.
What does caffeine do to someone with ADHD?
Some studies have found that caffeine can boost concentration for people with ADHD. Since it’s a stimulant drug, it mimics some of the effects of stronger stimulants used to treat ADHD, such as amphetamine medications.
