The short answer

What to do first

Memory changes: when to seek help, what to record, how a GP assessment works and how to support someone without taking over.

Start here: Write down a few specific examples, including what happened, roughly when, and what helped. Note whether the change is gradual, comes and goes, or appeared suddenly. Include the person’s own view and the effect on tasks they value, such as cooking, conversation, travel or managing appointments. Avoid quizzes and memory tests at home: they can cause distress and do not establish a diagnosis. Keep notes private and share them only with the person’s agreement, unless an immediate safety concern requires help.

Sudden or gradual change?
  1. Hours or daysNew confusion, altered attention or fluctuating alertness may be delirium and needs prompt medical assessment.
  2. Weeks or monthsA gradual change still needs assessment, but use urgent help if there is a sudden worsening or immediate danger.
  3. Write the baselineRecord usual memory and function, the exact onset, fluctuations and associated symptoms.
Causes clinicians may investigate
  1. Illness and body changesInfection, pain, constipation, dehydration, low oxygen, blood-sugar or other metabolic problems.
  2. Medicines and substancesNew medicines, dose changes, interactions, withdrawal, alcohol or other substances.
  3. Environment and sensesHospital change, poor sleep, reduced mobility, missing glasses or hearing aids can contribute.

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 making a practical decision for themselves, or supporting someone with their agreement.

Everyone forgets things sometimes. A pattern that is new, becoming more frequent or affecting familiar activities deserves attention, especially when the person is worried. Memory changes can be related to sleep, mood, pain, infection, hearing, medicines or other health conditions as well as dementia. An appointment is a way to understand what is happening, not a promise of a particular diagnosis. Sudden confusion is different from gradual change and needs urgent assessment.

Practical steps

1. Notice the pattern without testing

Write down a few specific examples, including what happened, roughly when, and what helped. Note whether the change is gradual, comes and goes, or appeared suddenly. Include the person’s own view and the effect on tasks they value, such as cooking, conversation, travel or managing appointments. Avoid quizzes and memory tests at home: they can cause distress and do not establish a diagnosis. Keep notes private and share them only with the person’s agreement, unless an immediate safety concern requires help.

2. Arrange the right appointment

The person can contact their GP themselves or ask someone they trust to help make the appointment. Explain that memory or thinking has changed and give a concrete example when booking. Ask for enough time, an interpreter or communication adjustment if useful, and permission for a supporter to attend. A clinician may ask about health, mood, medicines, sleep and daily life, and may arrange examination, blood tests or a memory-service referral. Assessment can take more than one appointment; ask what will happen next and how results will be shared.

3. Prepare medicines and health information

Bring an up-to-date list of prescribed medicines, over-the-counter products and supplements, and mention any recent changes. Tell the clinician about hearing or sight difficulties, pain, falls, infections, low mood, alcohol use or sleep disruption where relevant. These details can point to treatable contributors or affect how an assessment is interpreted. Do not stop or alter a medicine on your own. If attending is difficult, ask the practice whether a phone, home or other accessible appointment is possible.

4. Ask what the findings mean

Ask the clinician to explain what has been ruled out, what remains uncertain and whether another appointment or referral is planned. If a diagnosis is offered, ask what evidence supports it and whether other explanations were considered. The person can request information in writing and time to think before making non-urgent decisions. If the explanation is unclear, ask for it to be repeated in plain language or take a trusted supporter who has the person’s consent. A second conversation can be useful when feelings are strong.

5. Address immediate risks proportionately

Focus on a specific risk rather than removing independence wholesale. If meals are being missed, agree a reminder or shared meal; if medicines are confusing, ask a pharmacist or prescriber to review the routine; if a person is getting lost, plan a route and contact method together. Discuss driving concerns with the GP and relevant licensing authority rather than relying on family argument. If someone is in immediate danger, call emergency services. A sudden marked change in awareness needs urgent medical help.

6. Follow up and keep the person involved

Agree who will contact the service, when to expect an update and what to do if symptoms change before then. Ask whether a referral has been received and how to request accessible information or an interpreter. The person may want help with an appointment but not with finances or private conversations; ask each time rather than assuming broad permission. Keep a short record of questions and agreed next steps. Revisit the plan if it no longer fits, and invite the person to lead wherever they can.

Questions and checks

Common questions

When should I worry about memory changes?

Arrange a GP conversation when changes are recurring, getting worse, causing concern or making familiar tasks harder. One forgotten name on its own is common and does not diagnose dementia. Note what has changed and how it affects the person, rather than trying to score memory at home. A sudden change in confusion, alertness or ability to manage is different and needs urgent medical assessment.

Can memory problems be caused by something other than dementia?

Yes. Sleep problems, low mood, infection, pain, hearing or sight changes, medicine effects and other health conditions can affect thinking and memory. Some causes can be treated or improved, so an assessment matters even when dementia is one possibility. A GP can review the wider picture and arrange tests or referral. Do not stop a prescribed medicine without discussing it with the prescriber.

How do I get someone to see a GP if they refuse?

Start by asking what worries them and offer one practical choice, such as booking together or writing down questions. A person with capacity can decide whether to attend, even if relatives disagree. You can share relevant information with a GP, although the GP may not be able to discuss confidential details without permission. If the person becomes suddenly confused or is in immediate danger, seek urgent help.

What happens at a memory assessment?

The clinician usually asks about the change, health, mood, medicines and daily activities. They may examine the person, arrange blood tests or refer to a memory service for further assessment. The process varies locally and can take several appointments. Ask what a test can and cannot show, when results will be discussed, and how the person can receive information in a format they understand.

Should a person stop driving while memory is being assessed?

Do not make a blanket decision from a memory concern alone. Discuss specific driving difficulties with the person and their clinician, and follow the licensing rules that apply to the diagnosis and nation. If there is an immediate safety concern, avoid a risky journey while urgent advice is obtained. Keep the conversation focused on safe travel and alternatives, not blame or a family test of the person’s ability.

Differences across the UK

In England, the GP commonly coordinates initial assessment and referral to a local memory service. In Wales, Scotland and Northern Ireland, the GP also provides an entry point, but referral pathways, service names and local follow-up differ. Scotland has a national post-diagnostic support approach after diagnosis; Wales and Northern Ireland have their own NHS and trust arrangements, and local provision can vary. Ask the person’s GP practice which team handles memory assessment in their area and how results and follow-up are shared.
