What are the early signs of dementia in a parent?

Early signs of dementia usually build up over months: forgetting recent conversations, struggling with familiar tasks such as bills or cooking, losing words, confusion about time or place, and changes in mood or judgement. Dementia is not a normal part of ageing, and treatable conditions such as infections, thyroid problems or depression can cause similar symptoms, so see the GP.
The early signs of dementia in a parent are usually changes that build up over months: forgetting recent conversations, struggling with familiar tasks such as paying bills or cooking, losing words, becoming confused about time or place, and changes in mood or judgement. Dementia is not a normal part of ageing, and several treatable conditions cause similar symptoms, so the first step is always to see the GP.
What is dementia?
Dementia is a group of symptoms caused by diseases that damage the brain, getting worse over time. Alzheimer's disease is the most common cause. Others include vascular dementia, dementia with Lewy bodies and frontotemporal dementia, and some people have more than one type.
Different types can start differently. Alzheimer's disease often begins with memory problems; vascular dementia may first show as slower thinking or difficulty planning; frontotemporal dementia can start with changes in personality or behaviour rather than memory.
What are the early signs to look for?
The NHS lists common early symptoms as memory loss, difficulty concentrating, finding it hard to carry out familiar daily tasks, struggling to follow a conversation or find the right word, being confused about time and place, and mood changes. In a parent, that may look like:
Memory that affects daily life
- asking the same question or telling the same story several times in a short visit
- forgetting recent events, appointments or conversations
- relying more and more on notes, or on you, for things they used to manage
- losing things and being unable to retrace their steps
Trouble with familiar tasks
- unpaid bills, unopened post or muddled finances
- difficulty following a recipe they have made for years
- struggling with the washing machine, remote control or phone
- getting lost on a familiar route, or new dents on the car
Language and conversation
- stopping mid-sentence, searching for words or using the wrong word
- losing the thread of a conversation, especially in a group
Time and place
- confusion about the day, date or season
- getting up in the night thinking it is morning
Mood, behaviour and judgement
- becoming anxious, low, irritable or withdrawn
- losing interest in hobbies or seeing friends
- unusual decisions, such as responding to scams or giving away money
- less care with washing, clothes or the house
Seeing and judging space
- difficulty judging distances or steps, which can lead to falls
- trouble recognising objects or reading
How is this different from normal ageing?
Most people become a little slower to recall names or find words as they get older. The difference is whether the changes are getting worse and affecting everyday life.
| Usually normal ageing | May be a sign of dementia |
|---|---|
| Forgetting a name, then remembering it later | Forgetting recent events or conversations altogether |
| Occasionally missing a payment | No longer able to manage bills at all |
| Sometimes losing the thread of a thought | Regularly unable to follow a conversation |
| Taking longer to learn new technology | Struggling with familiar appliances used for years |
If you see several signs together, or a clear decline over weeks and months, it is worth acting.
What should you do if you are worried?
Keep a short record
Write down what you notice, when and how often, with specific examples. Note any changes in medicines, recent illness or stressful events. This helps the GP far more than a general sense that "something is wrong".
Talk to your parent
Choose a calm time. Use specific, gentle examples and focus on wanting to help: "You've seemed worried about keeping track of appointments. Shall we get it checked?" Your parent may be frightened or defensive, or may not notice the changes. It can take more than one conversation.
See the GP
The GP is the route to assessment. According to the NHS guide to getting a dementia diagnosis, the GP will ask about symptoms and everyday activities, do a physical examination, and may arrange blood and urine tests to rule out other causes such as depression, anxiety, infections, thyroid problems or medicine side effects. They will usually do a short memory test and, if dementia seems possible, refer your parent to a specialist, often at a memory clinic. The specialist may arrange a brain scan and more detailed tests.
Your parent can ask you to come to appointments. If your parent will not go, you can still tell the GP your concerns. The GP may not be able to share information with you without your parent's consent, but they can take what you say into account.
Why does an early diagnosis help?
- Some causes of memory problems are treatable, and ruling them out matters.
- Medicines can help some symptoms of some types of dementia for a time.
- Your parent can take part in decisions about money, care and the future while they are able.
- It opens the door to support, advice and financial help.
- It gives the family an explanation, which can make behaviour easier to understand and respond to.
What should you plan while your parent can still decide?
Lasting powers of attorney
In England and Wales, lasting powers of attorney let your parent choose people to make decisions for them if they lose capacity later. There are two types: property and financial affairs, and health and welfare. Your parent must have mental capacity when they make them, and they must be registered with the Office of the Public Guardian. GOV.UK explains the process and current fee. Scotland and Northern Ireland have their own power of attorney arrangements.
If your parent loses capacity without an attorney in place, family members may have to apply to the Court of Protection, which is slower and costs more.
Wills and finances
Check whether your parent has an up-to-date will and where it is kept. Make a list of bank accounts, pensions, insurance and regular bills. Consider setting up trusted access to accounts through the bank's own arrangements.
This is general information, not legal advice. A solicitor or Citizens Advice can help with your family's situation.
What help is available?
- Attendance Allowance. For people over State Pension age who need help because of an illness or disability, including dementia. It is not means-tested. GOV.UK lists the current rates. In Scotland, new claims are for Pension Age Disability Payment instead. People under State Pension age may be able to claim Personal Independence Payment.
- Council tax. In England and Wales, someone with a severe mental impairment certified by a doctor, who is entitled to a qualifying benefit such as Attendance Allowance, can be disregarded for council tax. If they live alone, no council tax may be due. The Alzheimer's Society explains council tax discounts and exemptions.
- Carer support. If you care for your parent, you can ask the council for a carer's assessment. Carer's Allowance may be available if you care for at least 35 hours a week and meet the other conditions.
- Care needs assessment. Your parent can ask the council for a free assessment of their care needs, whatever their savings.
- Specialist advice. The Alzheimer's Society, Dementia UK's Admiral Nurses, Age UK and Carers UK offer helplines and practical support.
Frequently asked questions
Is there a single test for dementia?
No. Diagnosis uses a combination of the person's history, a physical examination, blood and urine tests to rule out other causes, memory and thinking tests and sometimes brain scans. It may take more than one appointment.
Could it be something other than dementia?
Yes. Depression, anxiety, infections, thyroid problems and medicine side effects can all affect memory and thinking. Several are treatable, which is one reason to see the GP early rather than waiting.
My parent refuses to see the GP. What can I do?
Try linking the appointment to something they are willing to discuss, such as a health check or a physical problem. You can write to or speak to the GP about your concerns. Dementia charities' helplines can suggest ways to approach the conversation.
Is sudden confusion a sign of dementia?
Dementia usually develops gradually. Confusion that comes on over hours or days can be delirium, often caused by infection, dehydration or medicines, and needs urgent medical attention. Contact the GP or NHS 111, or call 999 in an emergency.
Should we set up power of attorney straight away?
If your parent is willing and still has capacity, yes. Lasting powers of attorney can only be made while the person understands what they are signing, and they take time to register.
