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.
If your child has ADHD, they may have low levels of a brain chemical called dopamine. That's part of a mix of their genes, environment, and brain function that experts believe may cause ADHD.
The condition is usually diagnosed in childhood, when difficulties arise during play and school, and it is marked by lack of concentration, short attention span, and physical restlessness (APA 1994; APA 2000). ADHD often is blamed on bad parenting, or a “bad” attitude.
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.
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.
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.
The onset of attention-deficit-hyperactivity-disorder (ADHD) in childhood is characterized by developmentally inappropriate levels of hyperactivity, impulsivity and inattention. A chronic deficit of serotonin (5-HT) at the synapse may trigger symptoms of ADHD.
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.
An ADHD brain ? processes thoughts differently.
So, when we're in the middle of a conflict, it can be hard to keep calm and think straight. We can feel extreme guilt, anger, sadness, or anxiety, and it can be hard to manage everything we're feeling.
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.
Because of differences in the brain structure of people with ADHD, they often find it incredibly difficult to feel motivated to stay focused when the task is uninteresting or unrewarding. A person without ADHD may be just as bored, but they can marshall their motivation and focus for long enough to slog through it.
Anecdotal evidence from adults sharing ADHD stories online suggests that many experience brain fog, low motivation, and fatigue. Tiredness is not part of the official diagnostic criteria for ADHD , but a handful of studies do suggest that some people with ADHD experience fatigue.
Individuals with ADHD often experience social difficulties, social rejection, and interpersonal relationship problems as a result of their inattention, impulsivity and hyperactivity. Such negative interpersonal outcomes cause emotional pain and suffering.
People who have ADHD are about 5 times more likely to be overweight or obese than those who don't have it.
ADHD: a disabling condition
It is recognized as a disability under the 1992 Disability Discrimination Act.
The five gifts of ADHD include creativity, emotional sensitivity, exuberance, interpersonal empathy, and being nature-smart (The Gift of Adult ADD, 2008).
Can you be introverted and have ADHD? Absolutely. People with ADHD have a diverse range of presentations and personality traits. This 2017 study of children with ADHD found that 58% of participants were introverted.
Entrepreneurs. There are some well-known very high-achieving ADHD entrepreneurs including Richard Branson, Bill Gates and Walt Disney. Richard Branson had no interest in anything academic. Still, once he was able to harness his talents and imagination in his own way, he began to build a phenomenal business empire.
Channing Tatum is one of the most widely recognized celebrities. He also happens to be an actor who has publicly shared his struggles with ADHD during his childhood and how his struggles at school affected him. In fact, he continues to work through related difficulties as an adult.
Hormonal Effects on ADHD
The loss of estrogen leads to a decrease in serotonin and dopamine levels in the brain. Women going through perimenopause report moodiness, sadness, irritability, fatigue, fuzzy thinking, and memory lapses. These may be more pronounced in women with ADHD.
You can inherit genes that boost risk for ADHD from your mother, from your father or from both parents. In a recent Norwegian study, inherited risk was somewhat higher when a child's mother had ADHD compared to their father, but researchers weren't certain why that would be.
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.
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…
