The GMS-AGECAT package was used in the initial assessment and 3-year follow-up of a random sample of 1,070 elderly people living in the community. A prevalence of 4.3% is found for dementia after confirmation of diagnoses by outcome at year 3. The overall incidence of dementia was 9.2/1,000 per year after partial adjustments for outcome of year 6. Incidence per year for sub-types of dementia were AD 6.3/1,000, vascular 1.9/1,000, and alcohol-related 1.0/1,000.
