Diagnosis, management and support

Learn about the signs, symptoms, and diagnosis of dementia, and find out how these symptoms can be managed.

Symptoms and when to seek help

The symptoms of dementia can vary depending on the person, the type of dementia and whether they have an early, middle or late stage of cognitive decline.  People living with dementia may experience a range of signs and symptoms, including:

  • memory loss
  • changes in personality
  • confusion about time or place
  • difficulty speaking, writing, and comprehending
  • loss of emotion, interest and enthusiasm
  • reduced capacity for decision-making
  • difficulty performing everyday tasks
  • irregular sleep.

The signs and symptoms of dementia may not be obvious. If you notice any changes that are unusual for you, see your doctor.


It is important to receive a confirmed diagnosis from your doctor. To diagnose you, your doctor will ask you to provide your medical history and may conduct:

  • physical and neurological examinations
  • cognitive and mental state assessment
  • blood or urine tests
  • specialist tests, such as a CT or MRI of the brain.

To learn more about the symptoms of dementia and how to receive a diagnosis, see the Dementia Australia website.

Dementia management

Currently there is no treatment available to cure dementia. Symptoms can often be managed, which can help people with dementia live meaningful and fulfilling lives after diagnosis.

Dementia management aims to maintain quality of life and improve a person’s ability to complete everyday tasks.

Non-medicinal approaches

Non-medicinal approaches can help to manage the challenging behaviours of dementia.

Non-medicinal approaches include:

  • psychological therapies, including cognitive behavioural therapies
  • alternative therapies, including multi-sensory therapy
  • memory training and activities
  • changes to a person’s home or other environment to ensure it is dementia-friendly.

Medicinal approaches

Medicines can often be used to manage the symptoms of dementia. Medicinal approaches aim to:

  • improve memory, thinking, and sleep
  • reduce delusions or hallucinations
  • reduce depression and anxiety.
