Causes of ADD / ADHD In Teenagers

Despite intensive research, the exact origins of ADD and ADHD have yet to be determined. There are, however, several theories about the causes of Attention Deficit Disorder and Attention Deficit Hyperactivity Disorder in adults, teens and children.

Chemical Imbalance and Neurotransmitters

Neurotransmitters help the human brain to form thoughts, store and recall information, and translate thoughts into physical actions. One of these neurotransmitters, dopamine, is abnormally low in children that have been diagnosed with ADD and ADHD. Since problems with memory and attentiveness are attributes of those with ADD and ADHD, researchers believe that low dopamine levels may be responsible. Research has indicated that in 60% of ADD and ADHD sufferers, the genes controlling dopamine production are in some way abnormal.

Another key neurotransmitter that may play a role in ADHD is acetylcholine, which is responsible for signaling and helping to control memory, attention, awareness, perception, reasoning and judgment.

Chemical imbalance is often associated with anxiety and depression, as well as ADHD, and explains why, in many cases, symptoms may cross-over.

ADD / ADHD and Diet

Throughout the last decade researchers have discovered that diet, which is closely tied to neurotransmitter synthesis and other bodily responses, may be an important factor in many of the symptoms associated with ADHD in children in teens.

A growing collective of research shows that even a moderate adjustment to diet, such as removing packaged and processed foods, sugary soft drinks and excessive sweets can significantly decrease symptoms of ADHD, like hyperactivity and the 'crash' that may often follow. It is thought that the highs and the lows of consuming sugars can affect a child's overall attentiveness, or lack there of.

In addition to creating a healthy diet of more natural foods, like fruits, vegetables and complex carbohydrates, clinical research indicates that supplementing your child's diet with specific vitamins and minerals, like the B-complex vitamins, zinc, and magnesium can further increase the chances of improvement.

Structural Differences

Not all teenagers affected with ADD and/or ADHD have low levels of neurotransmitters or a poor diet, and this has lead researchers to theorize that varying brain structures may have some effect on ADD and ADHD. The forebrain is the part of the brain that controls thoughts, behavior, and emotions. It controls the ability to reason, make decisions, and solve problems. A part of the forebrain, the frontal lobe, is most involved with judgment, behavior, memory, and motivation. Preliminary research has shown that a very small percentage of children with ADD or ADHD have forebrains about 10% smaller than those who do not have ADD or ADHD.
