This paper is a summary of the main findings concerning organic brain syndrome (O.S.S.) in a prevalence study carried out among the elderly population of the city of Rio de Janeiro, Brazil. The project selected three districts of the city - Copacabana, Meier and Santa Cruz - in view of a set of indicators. The study for the validation and reliability of the diagnostic instrument was carried out in the district of Copacabana. Prevelence results for organic brain syndrome were 5.9% in Copacabana, 9.84% in Meier and 29,75% in Santa Cruz. Several hypotheses have been formulated in the attempt to explain such diverse results within a single city. Associations with a variety of socio-economic indicators are presented. Dependence and loss of autonomy in elderly people are closely associated with organic brain syndrome. The results are compared with national and international findings.
