Dementia in Australia: Key Facts and Statistics

People living with dementia, with health care needs, will require all the help they can get, and this dementia research is a good way to start. This page shows how Australia records significant cases of dementia.

What is dementia?

What is dementia Dementia In Australia | My Delta Care

Dementia is a broad term that describes the gradual intellect and memory loss, and a decline in the ability to think rationally and socially.

Dementia is not a specific disease but a collection of symptoms of a long-term brain disorder such as Alzheimer’s disease or vascular dementia.

Symptoms of dementia

Diseases and injuries can be the underlying cause of dementia. But if it manifests in a loved one, dementia results can be from symptoms like depression, hormone imbalances, a different disease, and a nutritional condition. Loss of cognitive function and memory thinking are the most prevalent symptoms.

A person with dementia also has difficulty with the following:

It helps to understand more about people living with dementia—the risk factor, the rate of deaths, the prevalence of dementia, and even the impact. The following data were gathered from the Australian Bureau of Statistics and the Department of Health to help you understand dementia and Alzheimer’s. Australia does have a record number of people with this disease, and they could use help.

Risk factors of dementia

It is best to watch out for the following factors.

Age

As the greatest risk factor for Alzheimer’s disease, at the age of 65, the risk of developing Alzheimer's doubles every five years. Although far less common, younger-onset Alzheimer’s (also known as early-onset Alzheimer’s) affects age groups younger than 65. Up to 5 per cent of people with Alzheimer’s have the younger-onset disease.

Traumatic Brain Injury

The risk of Alzheimer’s disease increases after a moderate or severe traumatic brain injury like a skull fracture that causes amnesia or loss of consciousness for more than 30 minutes. People who sustain repeated brain injuries, such as athletes and those in combat, also have an increased risk of developing dementia and impairment of thinking skills.

Frequency of dementia

Data on the total number of people with dementia is currently not available. However, it is estimated that in 2020, there are between 400,000 and 459,000 Australians with dementia alongside Alzheimer’s disease.

It is expected to grow. The aging of Australia’s population will lead to an increase in individuals with Alzheimer’s over time, as the condition is increasingly common with advancing age and primarily affects older Australians. 

The cases of dementia are expected to increase dramatically.

Deaths

The rate of dementia death grew from 33 deaths to 42 per 100,000 people. It may reflect an increase in older people with dementia. It also changes how dementia deaths are recorded.
