The below link gives a high-level overview of the epidemiology, prognosis, comorbidity, diagnosis, pathophysiology, and treatment of schizophrenia. The prevalence of schizophrenia in men and women is similar but differs when it comes to the course and onset of illness. Throughout the course of schizophrenia, psychosis symptoms can come and go. Insomnia is predictive of the onset of psychotic occurrences, which approximately half of individuals with psychosis experience. Schizophrenia is a heritable disorder that is diagnosed through a variety of criteria.

Late-onset schizophrenia is less common than early-onset schizophrenia and occurs after 60 years of age. Approximately 25% to 30% of patients with schizophrenia are treatment resistant. The most evidence-based practice for length of medication treatment is for long-term antipsychotic use in treating first-episode schizophrenia for most patients, since relapse rates are over 80% when patients discontinue medication after several years of use. Relapsing involves hospitalization, recurrent psychosis, and considerable psychosocial impact.
