Objective: Psychosis is a set of symptoms that consist of delusions, hallucinations an thought disorders. In DSM 5, psychoses were collected under the title of schizophrenia spectrum and other psychotic disorders. The aim of this study was to investigate the prevalence of a family history of psychiatric disorders in patients with chronic psychosis and to examine the groups of these psychiatric disorders.
Material and Methods: A total of 282 patients with chronic psychosis, defined by DSM- 5diagnostic criteria, were included in this study. Sociodemographic parameters and family history of chronic psychosis patients were retrospectively reviewed.
Results: The mean age of the patients was 41.3 years, the mean age of onset of the disease was 22.8 years and the mean number of hospitalizations was 5.78 years. Patient group consisted of 94 (33.3%) males and 188 (66.7%) females. 48.6% (137/282) of patients with chronic psychosis had a history of psychiatric disorder in their first-degree relatives. In the diagnostic groups, there were 1.8% (5/282) schizoaffective disorder, 18.4% (52/282) schizophrenia, 6% (17/282) bipolar disorder, 5.7% (16/232) major depression, 13% , 8 (39/282) unspecified schizophrenia spectrum and other psychotic disorder, 2.5% (7/282) mental retardation, 0.4% (1/232) obsessive-compulsive disorder family history.
Conclusion: This study provides a platform for future studies to contribute to the development of early intervention and prevention approaches in populations at risk for further clarification of the role of family history in individuals with a family history
