Abstract in brief

  • This study systematically reviewed data from 31 research papers involving over 51,000 homeless individuals to estimate how common schizophrenia and other psychotic disorders are in this population, finding a notably high prevalence of these mental health conditions among homeless people.
  • The analysis showed that the prevalence of psychotic disorders, including schizophrenia, schizophreniform disorder, and schizoaffective disorder, was significantly higher in developing countries compared to developed ones, with about 29% in developing versus 18.8% in developed nations.
  • The findings highlight a critical need for improved mental health services and prevention strategies tailored to homeless populations worldwide to address the high rates of psychosis and their impact on this vulnerable group.

@cesifoti This is symptomatic of untreated schizophrenia (delusions) and the worst part is that part of the symptoms is inability to recognize you have it. It can also push toward having no address because one of the common delusions is that someone is tracking you https://t.co/0e1YwbiksM

Schizophrenia and Psychosis is prevalent in homeless people. Kinda challenges the common held belief that Mental illness does not make ppl dangerous. Clearly, w some diagnosis this is absolutely not the case. https://t.co/dgNDgaY0Uy

Let's not forget: - 30 - 85% of homeless suffer from mental illness - more than 60% refuse shelter because they impose rules (curfew, no drugs, etc) https://t.co/jF9nQg2twl https://t.co/SPmXIt91h0
