Attention deficit disorder or attention deficit hyperactivity disorder (ADD/ADHD) has varying causes that medical experts have not yet scientifically isolated. There is no medical exam or blood test that can diagnose the causes of these disorders – scientific behavioral assessments, neuro-imaging techniques, and cognitive abilities evaluation, however, aid in the diagnosis of ADD or ADHD.
ADD/ADHD is commonly attributed to is genes. Studies show that if a parent has ADD/ADHD, the likelihood that the child will have it, too, is 50 percent. Furthermore, an individual who suffers from ADD/ADHD is four times as likely to have had a relative with the same issue.
Currently, various researches on different genes are ongoing. These notably involve the brain chemical dopamine, which is responsible for the transmission of signals between nerves in the brain, and imbalances in the fatty acids, which are important for brain development and function.
Pregnancy complications are also seen as potential causes of ADD/ADHD. Children who were born under difficult circumstances, for instance, premature birth and low birth weight, have a higher risk of having ADD/ADHD. Exposure to toxins caused by cigarette smoke, alcohol, drugs, lead, PCBs, or pesticides during pregnancy could also hinder the baby’s brain development.
