‘Trends in prevalence of dementia for people accessing aged care services in Australia’.

With the population ageing, the numbers of people living with dementia is expected to increase in Australia to almost 1.1 million by 2058. However, these figures are solely based on the ageing population and it is unclear if the prevalence of dementia (the age-specific proportion of people with dementia) in Australia has changed over time.

Using the largest study of people who have accessed aged care services in Australia we examined the trends in the prevalence of dementia over time. We found that the prevalence of dementia had declined from 25.9% in 2005 to 20.9% in 2014 for people accessing home care services and from 50.0% in 2008 to 46.6% in 2014 for people accessing long-term residential care. These findings have important implications for future projection estimates of dementia and planning of aged care services.
