CORREDOR ROZO, Zayda Lorena et al. Descriptive study of 20 patients with schizophrenia in Boyacá, Colombia. Iatreia [online]. 2013, vol.26, n.3, pp.246-256. ISSN 0121-0793.

Schizophrenia is a multifactorial disease with high genetic heterogeneity and complex inheritance. In Boyacá, Colombia, we studied a group of 20 schizophrenic patients (16 men and 4 women) to establish their sociodemographic and clinical characteristics as well as their genetic and precipitating factors. The patients were analyzed using cytogenetic studies and a descriptive analysis of qualitative and quantitative variables. The disease frequently first manifested in young adults (average age of initiation: 22.5 years). The predominant subtype (8/20) was paranoid schizophrenia, and the onset was typically gradual (14/20). Precipitating factors were found in 15 patients: physical factors in nine patients, social factors in five patients and economic factor in one patient. All karyotypes were normal. Clinical features did not associate with either the sociodemographic characteristics or the genetic and predisposing factors, supporting the clinical heterogeneity of schizophrenia. Patients and their families received genetic counseling and explanations of the study's results, the possibility of recurrences and the risk of suffering the disease given an affected relative. Further and larger studies are required to determine if the factors evaluated in this study influence the development of the disease.
