What Causes Mental Illness?

There are three chemicals in the human brain that must be active in the proper amounts and location of the brain:

  1. Serotonin
  2. Norepinephrine
  3. Dopamine

If someone does not have enough of one or more of these chemicals active in the proper location in the brain, an imbalance occurs leading to disorders such as Depression, Bipolar and Schizophrenia.
