Is ADHD caused by a chemical imbalance in the brain?

Yes, to a degree. ADHD is caused by underdevelopment in certain regions of the brain. However, individuals with ADHD have less dopamine in the brain and respond to drugs that increase this chemical in the brain Another opinion Please go to the related link below I believe there is no solid scientific research to support the "chemical imbalance in the brain" theory of mental illness.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
