Document Summary
Schizophrenia: psychotic disorder characterized by major disturbances in thought, emotion, and behavior: disordered thinking in which ideas are not logically related, faulty perception and attention, flat or inappropriate affect and bizarre disturbances in motor activity. Prevalence 0. 2-2%, but the lifetime prevalence is 1%. Most measures are an underestimate because a lot of people don"t know they have schizophrenia and research doesn"t generally include homeless or hospitalized people. The prevalence varies across the world, with asian countries having the lowest rates. The prevalence is also higher in males (1. 4 ratio male:female). Most schizophrenics don"t need inpatient treatments if they get diagnosed early. The severity, development and course of schizophrenia is dependent on comorbidity (50% of schizophrenics have comorbid disorders). There are comorbid personality disorders (avoidant, paranoid, dependent and antisocial), and these affect the clinical management. Further studies showed that in the prodromal state (before developing schizophrenia) people use cannabis, so it might be linked with psychotic symptoms.
