With an estimated overlap rate as high as 55% between schizophrenia and PTSD, clinicians need to understand the links between these two disorders, as well as their differential diagnoses, in order to best assess and treat patients. The following slides delve into relevant data.

Schizophrenia Prevalence

Prevalence

  • Estimated between 0.25% and 0.64%
  • Over 2.2 million people in the US have schizophrenia – that’s 7.2 per 1,000 persons

Racial/Ethnic Disparities

  • Epidemiological studies suggest a similar prevalence among different racial groups
  • A number of studies, however, report higher rates of clinical diagnosis in Blacks versus Whites
  • One study found that Blacks were nearly 5 times more likely to be diagnosed with schizophrenia compared to Whites admitted to psychiatric hospitals

*Further research is needed to understand how race affects the diagnosis of schizophrenia.
