Young onset dementia (YOD) is defined as dementia diagnosed under the age of 65. It is also referred to as ‘early onset’ or ‘working age’ dementia. There are an estimated 42,000 people with young onset dementia in the UK.
As dementia is frequently, and wrongly, thought of as a condition associated with old age, the early symptoms of young onset dementia are not recognised and are attributed to other causes including depression, stress, physical health problems and relationship changes. This can lead to a significant delay (on average four years) in getting an accurate diagnosis, and appropriate post diagnosis support. This can have a negative impact on not just the person’s life but also the whole family. Particular issues faced by younger people with dementia in comparison with older people are:
more likely to have a rarer form of dementia affecting behavior and social functioning
more likely to have familial dementias
family members are more likely to report significantly higher psychological and physical distress
employment issues both of the symptomatic person and their partner
heavy financial commitments e.g. mortgage, children
younger and more dependent family
additional caring responsibility for parents
What causes young onset dementia?
There are differences in the types of dementia commonly diagnosed in younger people with dementia compared to those of an older age. Only about 34% of dementias diagnosed in younger people are Alzheimer’s type in comparison to about 60% in the older age group. Frontotemporal dementia is about 12% of the diagnosed cases of young onset dementia compared with just 2% in older people. In addition younger people are more likely to have rarer familial forms of dementia caused by genetic mutations including: familial Alzheimer’s disease, frontotemporal dementia and familial vascular dementia.
It is thought that the same causative factors may be present across the age range for non-familial Alzheimer’s and vascular dementias but the way it presents in the different age ranges can differ.
How does young onset dementia develop?
The early symptoms of young onset dementia can differ depending on the type of dementia and which parts of the brain it affects. Dementias affecting the frontal and temporal lobes of the brain are more common in younger people so it is more likely that the early symptoms may include changes in:
relationships with others
activities of everyday living
mood e.g. depression, anxiety
decision making and problem solving
Generally people think dementia is having a poor memory and being older, so the above symptoms in a younger person could be attributed to other life events. In addition the person may not recognise the changes in themselves and so can be resistive to seeking help or support.
Managing the effects of young onset dementia
Families living with the effects of young onset dementia state that they need:
early recognition of the signs and symptoms suggestive of dementia
accurate and timely diagnosis
awareness of their condition, especially from health and social care professionals
specialist information at the time of diagnosis
identification of a person who specialises in young onset dementia to support the family to work on a support plan to meet the family’s needs
counselling and relationship work
access to a specialist helpline
age appropriate meaningful occupation and activities
peer support groups
better communication between agencies
Early recognition and timely accurate diagnosis of dementia, combined with appropriate specialist support, can reduce the distress experienced by the whole family.
