ADD is a chemical reaction in the brain. Believe it or not, an ADD brain shows LESS activity than a normal brain. The neurons in the brain are not active enough to properly connect, causing inattentiveness, impulsiveness, hyperactivity in some, etc. Stimulant drugs raise the level of activity in the brain (by correcting the chemical imbalance) to that of a "normal" brain, increasing the neurons activity, therefore decreasing the other symptoms.

ADD causes brain neurons to refuse fusing with neural impulses exhibited by adjacent nuerons, by way of the synaptic gap. Stimulants, such as Adderall and Ritalin, will increase the amount of firing a neuron will do. Non-stimulant alternatives, such as Straterra, act as norepinephrine re-uptake inhibitors, which causes the firing neuron to not "take back" the chemical it fires to the adjacent neuron(s); this allows the chemicals to remain in the synaptic gap for a longer period of time, therefore increasing the chance that a receiving neuron will accept it.

ADHD is basically a difference in the way the brain works. I would not classify it as either chemical or physical, but possibly mental.

They help balance the neurotransmitters within the brain, thus allowing the person with ADHD to be calm down and focus.

ADHD is a developmental disorder of the brain; it doesn't affect brain cells in particular.

The answer is not entirely known, however ADHD is caused by underdevelopment within certain regions of the brain. ADHD may be entirely genetic, environmental, or a mixture of both. Research is being conducted to find the exact reason and cause for ADHD.

ADHD is how your brain works, the chemicals in your brain cannot be altered by Pepsi, and I think that ADHD can only be caused by the way your brain works from the start of your life, and nothing else can cause it.

No; concussions can cause symptoms similar to ADHD, but it is not ADHD. ADHD is a developmental disorder of the brain that occurs in childhood.

No, ADHD is not infectious. It is not a virus, but a lack of growth in certain regions of the brain; a person with ADHD has underdeveloped brain regions that control focus, attention, and planning.

ADHD is disorder resulting from an underdevelopment of certain regions of brain, particularly the areas that control focus, memory, and impulse. ADHD affects only the brain.

Since ADHD is a mental disorder it is in the brain. ADHD is caused by a chemical imbalance in the brain.

User Avatar

Probably not. ADHD is caused by an imbalance in brain chemistry that is almost certainly hereditary.

ADHD affects the frontal lobe (brain) but also more systems

No , he's getting brain damage from getting hit in the head too much. No He doesn't have ADHD nor does he have brain damage!! Get real

Adderall is a psychostimulant used to treat ADHD. The active ingredient in Adderall, amphetamine works by increasing the amount of dopamine available within the brain. Dopamine is a neurotransmitter that plays a role in memory, focus, and motivation. By increasing dopamine within the brain, individuals with ADHD can experience greater focus and more impulse control.

If you are taking ADHD pills and you do not have ADHD, and were not prescribed that medicine, then it is not only for one illegal, but it is also bad for you, it will affect your body in a different way than people with adhd, because the adhd medicines target their brain and temporarily fixes the negative symptoms of adhd by altering the brain chemicals. If you do not have the same brain chemicals, then the medicine will have different effects on your body, so yes it may very well be bad for your health.

It is because in ADD/ADHD patients there is a part of their brain that is running slower than the rest of the brain.. the stimulants activate 'that' part of the brain so it can run at the same speed as the rest of the brain.

Yes, to a degree. ADHD is caused by underdevelopment in certain regions of the brain. However, individuals with ADHD have less dopamine in the brain and respond to drugs that increase this chemical in the brain. Another opinion Please go to the related link below. I believe there is no solid scientific research to support the "chemical imbalance in the brain" theory of mental illness.

There is no particular physical appearance that is associated with ADHD. What is typically seen is certain behaviors, such as trouble focusing and difficulty sitting still.

User Avatar

No; there is numerous clinical studies, brain scans, and medical knowledge confirming that ADHD is linked to underdevelopment of certain regions of the brain. The evidence supporting ADHD is long reaching and not disputed by medical professionals. In some cases, the diagnosis for ADHD is questioned but not the disorder itself.

There isn't an opposite of ADHD par say. Schizophrenia would be the chemical opposite of ADHD since it involves too much dopamine in the brain as opposed to little dopamine in individuals with ADHD.

Try suffering a traumatic brain injury then you'll know.

The exact cause of ADHD is not known, although researchers continue to study the brain for clues. They suspect that there are several factors that may contribute to the condition, including:Heredity: The fact that ADHD tends to run in families suggests that children may inherit a tendency to develop ADHD from their parents.Chemical imbalance: Experts believe an imbalance of brain chemicals (neurotransmitters) that transmit nerve impulses may be a factor in the development of ADHD symptoms.Brain changes: Areas of the brain that control attention are less active in children with ADHD than in children without ADHD.Head injury:There are reports of children with head injuries, particularly with concussions, developing behavioral problems that may mimic ADHD.

ADHD is rooted in the underdevelopment of certain regions of the brain. However, the symptoms of ADHD affect a person in school, work, and even personal relationships.
