What is dementia?
Dementia describes a collection of symptoms that are caused by disorders affecting the brain. It is not one specific disease. Dementia affects thinking, behaviour and the ability to perform everyday tasks. It is a broad term used to describe a loss of memory, intellect, rationality, social skills and physical functioning. There are many types of dementia, including Alzheimer’s disease, vascular dementia, frontotemporal dementia and Lewy body disease. Dementia can happen to anybody, but it is more common after the age of 65.
What are the early signs of dementia?
The early signs of dementia are very subtle and vague and may not be immediately obvious. Some common symptoms may include:
- Progressive and frequent memory loss
- Personality change
- Apathy and withdrawal
- Loss of ability to perform everyday tasks.
Who gets dementia?
Most people with dementia are older, but it is important to remember that not all older people get dementia. It is not a normal part of ageing. Dementia can happen to anybody, but it is more common after the age of 65 years. People in their 40's and 50's can also have dementia.
Can dementia be inherited?
This will depend on the cause of the dementia, so it is important to have a firm medical diagnosis.
If you are concerned about the risk of inheriting dementia, consult your doctor or contact Dementia Australia to speak to a counsellor.
Most cases of dementia are not inherited.
