Dementia

Dementia is a group of conditions that gradually affect brain function. Common signs of dementia include memory loss, misplacing things and difficulty doing familiar tasks. Alzheimer’s disease is the most common cause of dementia. Dementia is more common in older people, but people under 65 years of age can develop younger onset dementia.

You can take steps to lower your risk of dementia at any age — it's never too early or too late to do so. Support is available for people with dementia and their carers. If you notice any symptoms, see your doctor. You can also call the National Dementia Hotline on 1800 100 500 for advice.
