Younger Onset Dementia

25,100 Australians under the age of 65 years are estimated to have younger onset dementia. Younger Onset Dementia has significant differences to dementia in older age.

What is Younger Onset Dementia?

The dementia experienced by people under the age of sixty-five is part of the clinical syndrome that encompasses a wide range of symptoms that result in the progressive decline in cognition. Memory, language reasoning, communication skills, capacity to organise daily life and other faculties are affected.

What we know...

Younger Onset Dementia has distinguishing characteristics and consequences:

  • Younger Onset Dementia is an umbrella term defined by age. It is not a specific condition. There are many types of dementia experienced by younger people including the common forms of Alzheimer’s disease, Vascular dementia, Lewy body dementia and Frontotemporal dementia, but also including a wide range of rarer conditions such as Posterior cortical atrophy (PCA), and many others.
  • Dementia may also be a coexisting dimension of other medical conditions including Motor neurone disease, Parkinson’s disease, Huntington’s disease, Multiple Sclerosis (MS), HIV/AIDs and others.
  • People with Younger Onset Dementia may have a very wide range of support needs arising from their different forms of dementia. It cannot be assumed that all people with Younger Onset Dementia are a homogenous population with similar needs.
  • Diagnosing dementia in younger people can be difficult and take many years before an accurate diagnosis is made. Patients are often misdiagnosed until dementia is definitively established as the cause.
  • Some people never receive a definitive dementia diagnosis, leaving families uncertain of the condition they are living with and how to best manage it.
  • The rate of progression of dementia in younger people can be faster. This requires particular care and  management strategies.
  • Younger Onset Dementia may include a higher proportion of people with familial Alzheimer’s disease resulting from an inherited genetic mutation passing through the generations. This applies to a small number of people.
  • People in their thirties, forties and fifties are at the period of family formation and development, and in their income generating prime. Most have substantial financial obligations. Dementia has significant financial and  social implications for the family members, particularly for the primary carer.
  • The lifestyle of people with Younger Onset Dementia, including their aims and aspirations, contrasts significantly to that of older people in the late stage of life.
