Although data on other drug use during pregnancy is not as complete, the pattern is similar. In addition, current evidence now shows that if the father was using drugs or alcohol at the time of conception, the genetic patterns of the sperm might be affected. This can also lead to later difficulties with the child. At this time, there is no known direct correlation between ADHD and long labor, but low APGAR scores that persist over minutes after birth appear to suggest a higher likelihood of learning problems later in life.
One thing we do know is that the brain of a child with ADHD is wired differently. ADHD is related to a neurochemical deficit and a specific neurotransmitter in specific areas of the brain. None of this, however, indicates that someone with ADHD cannot be a successful, productive adult. The anger that your son is feeling needs to be addressed, preferably by a professional psychologist or counselor who is very familiar with the needs of children with ADHD. It might also be helpful for your son to join a support group for teens. For example, some local CHADD (Children and Adults with Attention Deficit Disorders, 1-800-233-4050), LDA (Learning Disabilities Association, 1-888-300-6710) or IDA (International Dyslexia Association, 1-800-ABCD123) branches have groups just for teens.
