Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
Studies of twins and families make it clear that genetic factors are the major causes of ADHD, says Russell Barkley, Ph. D., author of Taking Charge of Adult ADHD. In fact, an estimated 75 to 80 percent of variation in the severity of ADHD traits is the result of genetic factors.
Dopamine and norepinephrine are two neurotransmitters that may play a role in 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.
Experts initially believed that ADHD occurs as a result of low levels of dopamine, but they have since realized that the relationship is a little more complicated. According to the Gulf Bend Center, people with ADHD may have a higher concentration of dopamine transporters in the brain.
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder. Research suggests that there is a link between dopamine levels and the development of ADHD.
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.
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.
Why? 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.

Attention Deficit Hyperactivity Disorder (ADHD) is a neurological disorder that affects a person's ability to control their behavior and pay attention to tasks.
A chronic deficit of serotonin (5-HT) at the synapse may trigger symptoms of 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. What are the main causes of ADHD?
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.
Many people think that ADHD is a result of trauma, but is it true? The answer is yes, but more for some people than others. The truth is that 90% of the time ADHD is not caused by trauma, but if the trauma is extreme enough, it can cause severe ADHD-like symptoms.
Many people with ADHD (Inattentive subtype and hyperactive subtype) find their brains work faster than people who don't have ADHD. Your non–linear way of thinking means you can problem solve, catch on to new ideas and have high speed conversations in a way that non–ADHDers just can't.
Some signs that you might be understimulated include: Lack of motivation. Physical hyperactivity. A sense of unease, making you feel "flat" or irritable.
A dopamine detox attempts to work by having a person stop any activity that creates high amounts of dopamine for a given amount of time. Activities can include spending time on the internet, eating a nice meal, and other pleasurable activities.
Some of the common foods that can cause ADHD reactions include milk, chocolate, soy, wheat, eggs, beans, corn, tomatoes, grapes, and oranges. If you suspect a food sensitivity may be contributing to your child's ADHD symptoms, talk to your ADHD dietitian or doctor about trying an elimination diet.
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.
I explain that ADHD is a neurological condition which includes symptoms of inattentiveness and hyperactivity. I then go onto listing the key traits that I struggle with such as: difficulties focusing, impulsiveness, procrastination and always feeling like I'm being 'driven by a motor'.
