Can dementia affect younger people?
Yes, dementia can affect younger people. Although it is more common in older age, some people develop dementia before the age of 65. This is often called young-onset dementia.
It can affect people in their 30s, 40s or 50s, though this is less common. For many families, the diagnosis comes as a shock because dementia is often associated with later life.
What is young-onset dementia?
Young-onset dementia is the term used when symptoms begin before age 65. It is not a single condition. Instead, it describes a range of diseases that can cause problems with memory, thinking, language and behaviour.
Some types are similar to those seen in older people, such as Alzheimer’s disease. Others are more likely to affect younger adults, including frontotemporal dementia and some rarer forms linked to inherited conditions.
Signs and symptoms to look out for
Symptoms can vary depending on the type of dementia. Common signs include memory loss, difficulty finding words, confusion, changes in mood, and problems with planning or concentrating.
Some younger people may first notice changes at work or in daily routines. They might struggle with finances, driving, or keeping up with tasks that used to feel easy. Behaviour changes can also be an early sign.
Why diagnosis can be delayed
Young-onset dementia is sometimes harder to spot because people do not expect dementia in someone who is still working or raising a family. Early symptoms may be mistaken for stress, depression, anxiety or the menopause.
This can lead to delays in getting the right help. If symptoms are affecting everyday life, it is important to speak to a GP and ask for further assessment if needed.
Getting support in the UK
A diagnosis of dementia at a younger age can have a big impact on work, finances and family life. Support may include specialist memory services, counselling, occupational therapy and advice about benefits or workplace adjustments.
Charities such as Dementia UK and Alzheimer’s Society can offer guidance and support. In England, Scotland, Wales and Northern Ireland, your GP can help you access local services and referrals.
Living with young-onset dementia
Although there is currently no cure for most types of dementia, many people continue to live active and meaningful lives after diagnosis. Getting support early can make a real difference to planning, treatment and quality of life.
Family, friends and employers can help by being patient, flexible and informed. If you are worried about symptoms in yourself or someone else, seeking medical advice early is the best first step.
