According to Port St Lucie Hospital, Schizophrenia was estimated to affect less than one percent of the United States population. The studies have also shown that Black Americans had a higher prevalence than white Americans.

The exact causes of Schizophrenia are unknown but several factors are associated with its onset.

Such factors include: Genetic factors-A predisposition to Schizophrenia can run in families and biochemical factors-certain biochemical substances in the brain are believed to be involved in Schizophrenia.

 It can also be caused by alcohol and drug use-drugs, particularly cannabis, triggering psychosis in people who are vulnerable to developing Schizophrenia. Stress has also been linked to one of the factors capable of causing Schizophrenia

The common symptoms of Schizophrenia include delusions, hallucinations, emotional withdrawal, disorganized thinking, and overly excitement.

The National Alliance on Mental Illness states that schizoaffective disorder affects about 0.3% of the population. Men and women experience Schizophrenia at a similar rate but men develop the illness at a younger age.
