How does an ADHD brain work?

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.


How does ADHD brain work differently?

Neuroimaging studies have revealed the structural differences in the ADHD brain. Several studies have pointed to a smaller prefrontal cortex and basal ganglia, and decreased volume of the posterior inferior vermis of the cerebellum — all of which play important roles in focus and attention.

How does an ADHD brain think?

The mind of a person with ADHD is full of the minutiae of life (“Where are my keys?” “Where did I park the car?”), so there is little room left for new thoughts and memories. Something has to be discarded or forgotten to make room for new information. Often the information individuals with ADHD need is in their memory…


What part of the brain is damaged in ADHD?

At the brain circuitry level, the superior longitudinal fasciculus (SLF) and cortico-limbic areas are dysfunctional in individuals with ADHD.

How does ADHD work in the brain in adults?

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.


Understanding the scattered (ADHD) brain



What hits dopamine for ADHD?

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.

What are the root causes of ADHD?

Recent studies link genetic factors with ADHD.
...
Causes of ADHD
  • Brain injury.
  • Exposure to environmental risks (e.g., lead) during pregnancy or at a young age.
  • Alcohol and tobacco use during pregnancy.
  • Premature delivery.
  • Low birth weight.


Is ADHD a traumatic brain injury?

Traumatic brain injury (TBI) is a frequent cause for hospitalization in young children and teenagers. It's associated with developing mental conditions, including secondary ADHD, a form of ADHD that develops following an injury.


Is ADHD a lack of dopamine?

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.

Is ADHD a chemical imbalance?

What is the cause or basis of ADHD? It is an impulse disorder with genetic components that results from imbalances of neurotransmitters.

What are positives of ADHD?

People living with ADHD may have a variety of skills and abilities beyond those of their neurotypical counterparts. These may include hyperfocus, resilience, creativity, conversational skills, spontaneity, and abundant energy.


Do ADHD brains ever fully develop?

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.

Are ADHD brains faster?

Many people with ADHD (Inattentive subtype and hyperactive subtype) find their brains work faster than people who don't have ADHD. Your non–linear way of thinking means you can problem solve, catch on to new ideas and have high speed conversations in a way that non–ADHDers just can't.

What is your brain missing when you have ADHD?

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.


Does ADHD brain age slower?

On average, the brains of ADHD children matured about three years later than those of their peers. Half of their cortex has reached their maximum thickness at age 10 and a half, while those of children without ADHD did so at age 7 and a half; you can see an evocative Quicktime video of this happening online.

What it feels like to have ADHD?

People with ADHD will have at least two or three of the following challenges: difficulty staying on task, paying attention, daydreaming or tuning out, organizational issues, and hyper-focus, which causes us to lose track of time. ADHD-ers are often highly sensitive and empathic.

Why do stimulants calm ADHD?

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.


What vitamin deficiency is ADHD?

People with ADHD have higher chances of being nutrient deficient than the average person. People with ADHD are twice as likely to suffer iron-deficiency anemia compared to members of the general population. ‍78.4% of children with ADHD are deficient in vitamin D compared to 48% of children without ADHD.

What is the burnout cycle in ADHD?

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.

Can ADHD cause brain fog?

ADHD is one of several health conditions that can cause brain fog. Many ADHD symptoms mirror brain fog symptoms. Brain inflammation may be behind some of them. ADHD can also cause sleep disturbances that make brain fog worse.


What kind of trauma causes ADHD?

Traumatic stress, apart from other factors like premature birth, environmental toxins, and genetics, is associated with risk for ADHD. The connection is likely rooted in toxic stress – the result of prolonged activation of the body's stress management system.

Can emotional trauma cause ADHD?

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.

Which parent passes down ADHD?

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.


Are you born with ADHD or is it caused?

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.

What are the 3 main symptoms of ADHD?

ADHD, also called attention-deficit disorder, is a behavior disorder, usually first diagnosed in childhood, that is characterized by inattention, impulsivity, and, in some cases, hyperactivity.
