      Mental illnesses are caused by a combination of biological, psychological, and environmental factors.

      For example, an abnormal balance of special chemicals in the brain called neurotransmitters (biological), a severe psychological trauma (psychological) or a dysfunctional lifestyle (environmental), among many others
