ADHD Causes
The specific causes of ADHD, Combined Type are not known. Researchers believe that ADHD can be caused by both genetic and environmental factors, but most cases are largely genetic. Researchers have also found some relation between mothers who have smoked tobacco and/or drank alcohol while pregnant and the development of learning and behavioral problems among their children. Contrary to some people's beliefs, ADHD is NOT caused by "bad" parenting skills, hormones, or watching too much television. (Koch, n.d.)
