By analysing de-identified data from the Historical National cohort of the Registry of Older South Australians (ROSA), we found that the age- and sex-standardized prevalence of dementia fell from 50% to 47% in long-term care 2008-2014 and from 26% to 21% in home care 2005-2014. This decline in dementia occurred in concurrence with a decline in cerebrovascular disease in long-term care but despite the prevalence of hypertension, diabetes, high cholesterol, malnutrition, obesity, depression and head injury increasing during this period. The decline in prevalence of dementia in these settings is critical to future projection estimates and for planning of services in Australia.
