The short answer

What to do first

Young-onset dementia is diagnosed before 65 and can affect work, parenting and relationships. Learn how to seek assessment and plan support.

Start here: Changes may include difficulty finding words, planning familiar tasks, judging distances, managing work, changes in behaviour or memory. Stress, depression, sleep problems, hearing loss and other health conditions can also affect thinking. Write examples with dates and ask someone who knows the person well to contribute only with their consent. A sudden change over hours or days needs urgent medical assessment because it may be delirium or another illness, not a gradual dementia process.

Scope of this guide

This guide helps you understand the options and questions to ask. It is not personal medical, legal or financial advice. Check the official sources for your nation and seek qualified help for high-stakes decisions.

Who this guide is for

People diagnosed with dementia before 65, and partners or family balancing work, children, finances and changing support needs.

Dementia diagnosed before the age of 65 is often called young-onset dementia. It can affect people who are working, raising children, caring for relatives or managing a mortgage, and the first changes may not be memory problems. A diagnosis can be frightening, but getting the right assessment can explain symptoms and connect a person and family with practical help. The person’s wishes, privacy and role in decisions should stay central.

How to approach the conversation

1. Notice changes without assuming the cause

Changes may include difficulty finding words, planning familiar tasks, judging distances, managing work, changes in behaviour or memory. Stress, depression, sleep problems, hearing loss and other health conditions can also affect thinking. Write examples with dates and ask someone who knows the person well to contribute only with their consent. A sudden change over hours or days needs urgent medical assessment because it may be delirium or another illness, not a gradual dementia process.

2. Ask a GP for a proper assessment

Explain what has changed and how it affects work, home life and relationships. The GP may review health, medicines, mood, sleep and other causes, then refer to a memory or specialist service. Take a list of questions and ask what tests are being considered, what they can show and when results will come. The person can ask to attend alone or with someone they trust. If an appointment is difficult, request adjustments such as more time, written information or a quieter room.

3. Plan for work, driving and money early

A diagnosis does not automatically decide whether someone can work or drive; the practical abilities and relevant rules need to be considered. Ask the clinical team about DVLA notification and the driving guide. At work, the person may choose to talk with an employer about adjustments, occupational health or a gradual change in duties. Review bills, benefits, insurance and important documents while the person can express preferences. A power of attorney is a separate legal choice and should be made with independent advice, not under pressure.

4. Include children and family in an age-appropriate way

Children often notice changes and may blame themselves if nobody explains what is happening. Agree together what to tell them, using simple honest language and giving them room to ask questions. Avoid making children responsible for adult care. Discuss routines, school support and who they can talk to. Partners and relatives may grieve the future they expected while still valuing ordinary family life. Support can include counselling, peer groups or help from a specialist dementia nurse. Keep routines and relationships where they remain meaningful to the person. A family meeting can clarify what children have been told, what the person wants shared with friends and who can answer questions at school or work. Revisit these agreements as the family’s understanding changes. If a child or partner seems distressed, ask the GP, school or dementia service what emotional support is available.

5. Ask for support that fits the person’s stage of life

A local dementia service, social worker or specialist team can help with care planning, benefits, work and family needs. Young-onset services are not available in every area, so ask the GP or memory service what local and national support exists. Dementia UK’s Admiral Nurses can offer specialist information, while the Young Dementia Network shares resources and peer support. A council needs assessment and a carer’s assessment are separate routes and can help identify practical support. Ask explicitly whether the service understands issues such as parenting, employment, relationships and financial commitments that may not arise in older-age dementia pathways. If the first contact cannot answer, request a referral to a colleague or a national organisation with relevant experience.

6. Keep plans flexible and the person involved

A diagnosis does not remove a person’s right to make decisions. Ask what matters now and revisit support as needs change. Keep copies of assessment letters, medication lists, contact details and preferences in an agreed place. Discuss advance care planning and decision-making documents early enough for the person to take part, but do not rush a choice. If communication becomes harder, use the person’s preferred way of communicating and allow time for them to answer.

Prompts and boundaries

Common questions

What does young-onset dementia mean?

It describes dementia diagnosed before the age of 65. It is not a separate single disease; different conditions can cause it. Some people first notice language, planning, behaviour or visual-spatial changes rather than obvious memory loss. The diagnosis should follow an assessment, because other health problems can look similar. Ask a GP to investigate persistent changes that affect daily life.

How do I get assessed for young-onset dementia?

Start with a GP appointment and bring examples of changes, when they began and how they affect everyday tasks. The GP can consider other causes and arrange referral to a memory clinic or specialist service. Ask who will coordinate tests and when to expect results. If specialist services are limited locally, the GP can explain alternative assessment routes and how to access support while waiting.

Can I keep working after a diagnosis?

Some people continue working, sometimes with adjustments, while others decide to change or leave work. A diagnosis alone does not settle the decision. Consider the tasks that are becoming difficult, safety, fatigue, income and what the person wants. They may choose to speak with an employer or occupational health service. Seek independent benefits advice before making a major financial decision.

Will I have to stop driving?

Not automatically, but a person must meet the relevant eyesight and medical standards and may need to notify the licensing agency. Ask the clinical team about DVLA in Great Britain or DVA in Northern Ireland and whether an assessment is appropriate. If driving is unsafe, agree alternatives early and preserve the person’s control over travel decisions as far as possible.

Where can families get specialist support?

Ask the memory service, GP or council about local dementia support and whether a young-onset service is available. Dementia UK’s Admiral Nurses provide specialist information, and the Young Dementia Network has resources for people affected at a working age. A carer’s assessment may identify support for a partner or relative. Availability differs locally, so request a named contact and a written next step.

Differences across the UK

The NHS pathway and social-care arrangements differ across England, Scotland, Wales and Northern Ireland, and specialist young-onset services are not available everywhere. Ask the GP or memory service who coordinates assessment and what support exists locally. Benefits and legal documents also depend on nation and personal circumstances. Use the linked UK-wide guides for working, driving and decision-making, and confirm nation-specific rules with the responsible service.
