Several people who suffer from schizophrenia are not always violent and they do not cause harm to others. The disease is not associated with childhood experiences or inadequate parental guidance and the signs and symptoms differ from one person to another (Swerdlow, 2010).
The primary cause of schizophrenia is not very precise, and multiple factors have been associated to predispose and cause the disease.

An imbalance of these neurotransmitters affects an individual’s brain reaction to stimuli. This provides an explanation why an individual with schizophrenia occasionally gets overwhelmed by some sensory stimuli such as loud music or dazzling lights, which normal individuals easily handle (Roder & Medalia, 2010).
