By Nick Brock and I have ADHD
Body System and Nervous System
The nervous system has the brain and spinal cord. The brain has transmitters that tell if you are in pain, your emotions, language, sight, smell, taste and how you move. The spinal cord controls movement and reflexives.When you have ADHD, the brain has less neurotransmitters, dopamine and norepinephrine. The messages get messed up.
ADHD is genetic and is inherited from your parents. Six million children have ADHD. It can also be caused by brain injury, lead poisoning, low birth weight, or alcohol or drug use during pregnancy.
