What is younger onset dementia?

Younger onset dementia, also known as early onset dementia, is any form of dementia in people under the age of 65.

Although dementia is much less common in people under 65, it can be diagnosed in people in their fifties, forties and even thirties. As of 2019, approximately 27,247 Australians were living with younger onset dementia.

Dementia is a catch-all term for a large group of cognitive illnesses and conditions. You can have one or more types of dementia.

Since dementia is not as common in working-age people, it can often go unnoticed. But recognising the signs and symptoms and getting support sooner can drastically improve your quality of life.

Dementia can happen at any age

Dementia can happen to anyone. It can come as an enormous shock but for some, it may also be a relief. You or your family may finally have an answer for what’s changed.

There is no medical difference between dementia and younger onset dementia. However, younger onset dementia comes with unique social, emotional, and financial challenges. At the time of diagnosis, a person may be:

  • In full-time employment
  • Actively raising a young family
  • Financially responsible for a family
  • Physically strong and healthy.
