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.
More Dopamine, Please
However, dopamine-increasing behaviors are even more gratifying to ADHD brains. Key aspects of the reward system are underactive in ADHD brains, making it difficult to derive reward from ordinary activities.
One study found that kids with ADHD don't have the same brain connections as those without. An ADHD brain may have different connections between the frontal cortex and the visual processing area. This means that people with ADHD might process things differently than people without the condition.
People with ADHD have at least one defective gene, the DRD2 gene that makes it difficult for neurons to respond to dopamine, the neurotransmitter that is involved in feelings of pleasure and the regulation of attention.
If your child has ADHD, they may be low in dopamine but high in something called dopamine transporters. That's because their low dopamine may actually result from having too many of the transporters that take dopamine out of their brain cells.
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.
An imbalance in the transmission of dopamine in the brain may be associated with symptoms of ADHD, including inattention and impulsivity.
Stimulant medications that treat ADHD can prevent the reuptake of dopamine, increasing brain levels of the chemical. Lifestyle changes can also help, especially in conjunction with standard ADHD treatments. Exercise, a healthy diet, and therapy all offer potential benefits.
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.
Brain MRI is a new and experimental tool in the world of ADHD research. Though brain scans cannot yet reliably diagnose ADHD, some scientists are using them to identify environmental and prenatal factors that affect symptoms, and to better understand how stimulant medications trigger symptom control vs. side effects.
Executive functions have other roles which affect how someone thinks. In people with ADHD, these executive dysfunctions impact thinking in numerous ways. People with ADHD don't really think faster than people without it, but it can sometimes seem like they do. People with ADHD do think differently though, in a sense.
Treatment. Standard treatments for ADHD in adults typically involve medication, education, skills training and psychological counseling. A combination of these is often the most effective treatment.
Brain Structure
The largest review ever of ADHD patient brain scans was carried out at Radboud University Nijmegen Medical Centre and published in 2018. Parts of the ADHD brain mature at a slower pace (approximately one to three years) and never reach the maturity of a person who does not have ADHD.
Some of the common foods that can cause ADHD reactions include milk, chocolate, soy, wheat, eggs, beans, corn, tomatoes, grapes, and oranges.
Finally, supplementing vitamins B and C can also help alleviate ADD and ADHD symptoms. Vitamin C, like zinc, iron, and magnesium, is used to produce neurotransmitters like dopamine. Additionally, vitamin B deficiency is linked to irritability and fatigue in children.
Low dopamine symptoms can include a lack of enthusiasm for things you usually enjoy and are interested in. Plus, having low dopamine may have a low sex drive. You may also experience physical troubles such as insomnia, tremors, muscle spasms, stiffness, and difficulty moving.
INCUP is an acronym that stands for interest, novelty, challenge, urgency, and passion. The term was first proposed by psychologist William Dodson, who suggested that these five things are the top motivating factors for someone with ADHD.
A chronic deficit of serotonin (5-HT) at the synapse may trigger symptoms of ADHD.
Is ADHD inherited from Mom or Dad? You can inherit genes that boost risk for ADHD from your mother, from your father or from both parents.
VAST (SM) stands for Variable Attention Stimulus Trait
Dr. Hallowell and Dr. Ratey coined this new name for ADHD thereby expanding its reach to include millions of people.
Rather, the rise seems to be due to an increase in access to healthcare; a decrease in stigmatization about receiving mental health care; and greater awareness of the symptoms of ADHD among clinicians, guardians, educators, and patients. In the past, ADHD was only diagnosed in children who were hyperactive.
