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 affects brain functioning in several ways. The condition has links to abnormal cognitive, behavioral, and motivational functioning. ADHD can affect the regulation of moods, emotions, and brain cell connections. It can also affect communication between different areas of the brain.
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.
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…
At the brain circuitry level, the superior longitudinal fasciculus (SLF) and cortico-limbic areas are dysfunctional in individuals with ADHD.
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.
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.

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.
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.
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.
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children.
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.
Studies show working memory is less effective in children and adults who have ADHD than in those who don't. Long-term memory. People with ADHD often don't do well on tests of long-term memory.
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.
Adults with ADHD may find it difficult to focus and prioritize, leading to missed deadlines and forgotten meetings or social plans. The inability to control impulses can range from impatience waiting in line or driving in traffic to mood swings and outbursts of anger. Adult ADHD symptoms may include: Impulsiveness.
A: ADHD brains need more sleep, but find it doubly difficult to achieve restfulness. It is one of those ADHD double whammies: ADHD makes it harder to get enough sleep, and being sleep deprived makes it harder to manage your ADHD (or anything else).
Symptoms of hyperactivity in ADHD tend to improve the most with age, usually decreasing in late childhood and early adolescence. Examples of notably improved hyperactive symptoms include: seeming to constantly “be on the go”
What is the cause or basis of ADHD? It is an impulse disorder with genetic components that results from imbalances of neurotransmitters.
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.
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.
