Dementia is a significant and growing health and aged care issue in Australia that has a substantial impact on the health and quality of life of people with the condition, as well as for their family and friends.

Dementia is a term used to describe a group of similar conditions characterised by gradual impairment of brain function. Changes due to the condition may affect memory, speech, cognition (thought), behaviour, mobility and an individual’s personality, and their health and functional ability decline as the disease progresses. Dementia is a progressively fatal condition, with most people in the advanced stage of dementia requiring constant care and support, often provided by residential aged care services. The number of Australians living with dementia is projected to increase with more Australians living to older ages.

This page presents reports and statistics that are specifically focused on dementia, but additional information on dementia can be found under Aged care, Older people and Palliative care services.
