Key aspects of the reward system are underactive in ADHD brains, making it difficult to derive reward from ordinary activities. These dopamine-deficient brains experience a surge of motivation after a high-stimulation behavior triggers a release of dopamine.
People with ADHD may compulsively seek high-dopamine activities and stimulus to turn their brains on, which is why people with ADHD can be more likely to engage in impulsive and risky behaviors. Anything that triggers a strong burst of dopamine in the brain may be sought after by an individual.
Coping strategies can ease ADHD symptoms like hyperactivity, impulsive urges, and difficulty focusing. Taking exercise breaks and setting timers can help refocus your thoughts if your mind wants to wander.
Untreated ADHD in adults can lead to mental health disorders like anxiety and depression. This is because ADHD symptoms can lead to focus, concentration, and impulsivity problems. When these problems are not managed effectively, they can lead to feelings of frustration, irritability, and low self-esteem.
In response to trauma, a child's developing brain can become programmed to “look out” for behaviour, activities or events that they perceive as threatening. This “hyper-vigilance” can often mimic hyperactivity and distractibility associated with 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.
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.
Some signs that you might be understimulated include: Lack of motivation. Physical hyperactivity. A sense of unease, making you feel "flat" or irritable.
Differences in emotions in people with ADHD can lead to 'shutdowns', where someone is so overwhelmed with emotions that they space out, may find it hard to speak or move and may struggle to articulate what they are feeling until they can process their emotions.
The symptoms include an inability to focus, being easily distracted, hyperactivity, poor organization skills, and impulsiveness. Not everyone who has ADHD has all these symptoms. They vary from person to person and tend to change with age.
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.
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.
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.
The ADHD brain has been described as an “interest-based nervous system”: It seeks high-stimulation situations, stronger incentives, and more immediate rewards, which trigger a quick and intense release of dopamine and with it a rush of motivation. Hyperfocus. Dopamine is the brain's most intense reward.
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 children with ADHD have chronically low levels of dopamine, they are more likely than other children to crave and eat sugary or carbohydrate-heavy foods.
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.
People with ADD/ADHD tend to have low levels of dopamine, so it's a good idea to eat foods that tend to increase dopamine such as beef, poultry, fish, eggs, seeds (pumpkin and sesame), nuts (almonds and walnuts), cheese, protein powders, and green tea.
Low levels of dopamine can make you feel tired, moody, unmotivated and many other symptoms. Treatments are available for many of the medical conditions linked to low dopamine levels.
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.
Does ADHD affect IQ? A popular misconception is that all children with attention deficit hyperactivity disorder (ADHD) are naturally smarter and have a higher IQ than children without ADHD. However, there is no correlation between this condition and intelligence.
These may include hyperfocus, resilience, creativity, conversational skills, spontaneity, and abundant energy. Many people view these benefits as “superpowers” because those with ADHD can hone them to their advantage. People with ADHD have a unique perspective that others may find interesting and valuable.
ADHD burnout is often something a little deeper. It refers to the cycle of overcommitting 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.
