Abstract: Background: The increase of the rates of age-related diseases as dementia, especially Alzheimer's disease (AD), is projected with the aging of the world population. Subjects with Mild Cognitive Impairment (MCI) are considered a population at risk for developing dementia. However, MCI incidence rates and rates of conversion to dementia have shown considerable variability that could be partially attributed to characteristics of the sample and to different criteria. Objective: To determine the incidence of dementia and mild cognitive impairment in a cohort of community-based healthy elderly individuals; to determine the demographic, clinical and social variables associated with the development of cognitive impairment; and to assess the risk of progression of individuals with mild cognitive impairment to dementia compared with cognitively normal subjects. Methods: Data were derived from a cohort of elderly community residents (N = 345), who were initially healthy and independent (PALA – Porto Alegre Longitudinal Aging – study). The follow-up of a maximum of eight years was used to evaluate the incidence of AD and MCI. To evaluate the progression of MCI to dementia due to AD we set off the 10year follow-up, including the previous 8-year of the first analysis, and consider the maximum of 70 months (mean 45 months) for these new outcomes. Participants who met the inclusion criteria of the study and consented to participate were evaluated with a detailed clinical interview consisted of demographic, clinical and social variables. Psychiatric symptoms were assessed with the SRQ scale (Self Report Questionnaire), the MADRS (Montgomery-Asberg Depression Rating Scale), and the Diagnostic and Statistical Manual of Mental Disorders (4th edition, DSM-IV) criteria for Major
