ADHD is caused by changes in brain chemicals called neurotransmitters. These chemicals help send messages between nerve cells in the brain. The neurotransmitter dopamine (pronounced: doe -puh-meen), for example, stimulates the brain's attention centers. ADHD arises from a combination of various genes, many of which affect dopamine transporters. Dopamine transporter levels that indicate ADHD, but the brain's ability to produce dopamine itself .The estimated contribution of non genetic factors to the contribution of all cases of ADHD is 20 percent. The few environmental factors implicated fall in the realm of biohazards and include alcohol, tobacco smoke, and lead poisoning. Complications during pregnancy and birth-including premature birth -might also play a role. It has been observed that women who smoke while pregnant are more likely to have children with ADHD. This could be related to the fact than nicotine is known to cause hypoxia (lack of oxygen) in utero , but it could also be that ADHD women have more probabilities to smoke both in general and during pregnancy, being more likely to have children with ADHD due to genetic factors. Children who live in old buildings in which lead still exists in the plumbing or in lead paint that has been painted over may be at risk.
