Overview

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 was the second leading cause of death in 2018, and is expected to affect up to 550,000 by 2030.

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.
