The Effect Of ADHD On The Brain

Scientist have found that there are ten known genes that causes ADHD. These genes involve the dopamine receptors or transporting molecules (Batts). “Some of these genes may increase dopamine receptors on certain parts of the brain which may have the effect of depleting dopamine” (Batts). Let’s rewind for a second. ADHD is classified as a neuropsychiatric disorder. Neuro relating to nerves or the nervous system of the brain. The brain has a specific neurotransmitter deficiency, norepinephrine. Norepinephrine requires dopamine in order to function correctly. The building basic for norepinephrine molecule is dopa, which converts into dopamine, then into norepinephrine. A person with ADHD this process is reformed by a certain gene creating low levels of norepinephrine (Batts). Moving forward, dopamine are neurotransmitter, a chemical that moves though out
It is responsible for: movement, memory, pleasure seeking, behavior and cognition, attention, sleep, mood, and leaning (News Medical). Too much or too little dopamine will cause a person to act abnormal. What is happening with a person with ADHD, too much dopamine is moving to parts of the brain and removing the dopamine that are already there. The person starts to feel unmotivated, depressed, unfocused, mean, and may misinterpret a situation.
Besides brain structure, chemicals imbalance and nerve pathways there are other factors that contribute to the cause of ADHD. Environmental factors such as stress during pregnancy, smoking, alcohol and drug uses, environmental toxins, birth complications, low birth weight or exposure to lead. It has been
