The Neuroscience of the ADHD Brain
ADHD brains have low levels of a neurotransmitter called norepinephrine.
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 affect the brain?
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.
Is ADHD a chemical imbalance in the brain?
Attention deficit hyperactivity disorder (ADHD) Someone with ADHD might have significant attention problems, appear restless, fidgety, overactive and impulsive. ADHD is a neurobehavioral condition which can result from a number of factors that affect how the brain develops and functions.
What chemical is lacking in ADHD?
Dopamine transporters and ADHD
It’s responsible for feelings of pleasure and reward. Scientists have observed that lower levels of dopamine are associated with symptoms of ADHD.
What in the brain causes ADHD?
Heredity is the most common cause of ADHD. Other risk factors for ADHD have to do with factors that can influence brain development and functioning such as exposure to toxic substances in the developing fetus and acquired brain injury due to trauma or disease.
Does ADHD affect intelligence?
Depending on the severity of symptoms, ADHD can affect a person’s ability to function at school and work. According to a 2010 study published in Psychological Medicine, adults who had both high IQs and ADHD were found to have overall less cognitive function compared to other participants who had high IQ but not ADHD.
Does ADHD affect your memory?
ADHD Is Associated With Short-Term Memory Problems
Although they do not have problems with long-term memories, people with ADHD may have impaired short-term — or working — memory, research shows. As a result, they may have difficulty remembering assignments or completing tasks that require focus or concentration.
Can a brain scan show ADHD?
ADHD can show up differently in each child affected, which makes it harder to determine the diagnosis. Some doctors have started using new methods to diagnose ADHD. Since ADHD is a neurodevelopmental disorder, high-tech brain scans based on blood flow and brain wave activity may help give insight into this condition.
Is ADHD a form of autism?
The symptoms of autism spectrum disorders and ADHD overlap. Most children on the autism spectrum have symptoms of ADHD — difficulty settling down, social awkwardness, the ability to focus only on things that interest them, and impulsivity. ADHD itself, however, is not part of the autism spectrum.

What is wrong with ADHD brain?
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 deficiency causes ADHD?
Vitamin B: Deficiencies in B vitamins — particularly B6 — can cause irritability and fatigue in children and adults with ADHD. Adequate B6 levels — achieved through nutritional changes or a supplement — can increase alertness and decrease anxiety-like symptoms.
Is ADHD the same as bipolar?
Bipolar disorder is primarily a mood disorder. ADHD affects attention and behavior; it causes symptoms of inattention, hyperactivity, and impulsivity. While ADHD is chronic or ongoing, bipolar disorder is usually episodic, with periods of normal mood interspersed with depression, mania, or hypomania.
