[10 cases of psychosis in Mapuche indians]
Abstract:
Ten Mapuche indians have been studied with the purpose of observing the particularities of mental disorders in this ethnic group, composed of rural migrants. In each case a syndromatic and an etiological diagnosis has been made. Our cases correspond to six women and four men with an average age of 24.5 years. All are single with a low educational level. Our results show a great frequency of the acute oniroid psychotic syndrome. These results agree with a retrospective study made by Muñoz et al (1966) who found the same syndrome in 66.6% of their Mapuche patients against only 16.3% in non Mapuche chilean patients.
