ADHD was the first disorder found to be the result of a deficiency of a specific neurotransmitter — in this case, norepinephrine — and the first disorder found to respond to medications to correct this underlying deficiency. Like all neurotransmitters, norepinephrine is synthesized within the brain.
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.
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.
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.
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.
Five case-control studies reported the OR for developing ADHD based on vitamin D status; the meta-analysis of their data revealed that lower vitamin D status is significantly associated with the likelihood of ADHD (OR: 2.57; 95% CI: 1.09, 6.04; I2 = 84.3%).
The cause(s) and risk factors for ADHD are unknown, but current research shows that genetics plays an important role. Recent studies link genetic factors with ADHD. In addition to genetics, scientists are studying other possible causes and risk factors including: Brain injury.
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.
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.
ADHD is not on the autism spectrum, but they have some of the same symptoms. And having one of these conditions increases the chances of having the other. Experts have changed the way they think about how autism and ADHD are related.
Magnesium for Relaxation and Sleep
Healthy levels of magnesium in the blood can help relax individuals with ADHD. Some small studies8 have shown that adding magnesium supplements decreases some symptoms of ADHD.
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.
Add a Daily Dose of Nuts and Chocolate. Nuts and seeds are good sources of the antioxidant vitamin E, which has been linked in some studies to less cognitive decline as you age. Dark chocolate also has other powerful antioxidant properties, and it contains natural stimulants like caffeine, which can enhance focus.
B vitamin deficiency
A lack of vitamins B12 and B6 can lead to hyperactivity. Supplementing with B vitamins helps improve ADHD symptoms in children who are deficient.
Many American children have abnormally low levels of vitamin D. Newer research shows that children with ADHD have lower vitamin D levels than children without the condition. One study showed that expectant mothers with low vitamin D levels had a higher likelihood of their children having ADHD.
People with ADHD often lack magnesium and zinc and supplement of these vitamins may improve hyperactivity, impulsivity, attention and memory. Several studies have shown that, at large, people with ADHD have less magnesium (Mg) and zinc (Zn) in their bodies than the control groups that don't have ADHD.
Adolescents who have a borderline level of vitamin B12 can develop signs of cognitive changes. A combined vitamin, mineral, amino acid treatment may be effective in improving attention and self-control in children with ADHD.
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.
Furthermore, they many times find simple social interactions painful or awkward. This all results in not always knowing how to interact with others or pick up on social cues. As a result, eye contact just doesn't happen often if at all.
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…
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.
