Most people forget things from time to time, and occasional lapses — misplacing keys, walking into a room and forgetting why — are usually a normal part of life and ageing. The time to think about when to worry about memory loss is when forgetfulness becomes persistent, is getting noticeably worse, or starts affecting your day-to-day life. In that case, the NHS advises seeing a GP, because memory problems often have causes that can be treated, and any treatment tends to work better when started early.
Key takeaways
- Occasional forgetfulness is common and, on its own, rarely a sign of disease; what matters most is the impact on everyday functioning, according to HealthAnswers.
- Memory problems can have many treatable causes, including stress, anxiety, depression, vitamin B12 deficiency, thyroid problems and some medicines, per the NHS.
- See a GP if memory issues keep happening, affect daily life, or worry your family — and don’t try to self-diagnose the cause.
- If you’re concerned about an older relative, encourage them to see a GP; if dementia is found early, its progress can be slowed in some cases, says the NHS.
What counts as normal forgetfulness — and what doesn’t?
Memory loss can simply be a natural part of getting older, the NHS notes, and it can also be caused by things that are common and treatable. Mild lapses — occasionally misplacing your keys, briefly forgetting a name, needing a list to remember errands — fall firmly into the everyday category for most people.
What distinguishes normal ageing from something more significant is the effect on everyday function. Memory problems that interfere with daily life — managing money, following a recipe you’ve made for years, getting lost in familiar places, or lapses that worry the people around you — need proper assessment rather than reassurance from an internet search.
Everyday lapses vs signs worth checking
As a rough guide drawn from UK health guidance:
- Usually reassuring: occasionally forgetting where you put something, a name on the tip of your tongue, needing reminders for routine tasks.
- Worth discussing with a GP: memory problems that keep happening, affect your day-to-day life, or prompt concern from family, according to the NHS and Devon Partnership NHS Trust.
Neither list is a diagnostic tool. The point is simple: if forgetfulness is bothering you or the people who know you best, that itself is a good enough reason to get checked.
What causes memory problems besides dementia?
This is where a lot of unnecessary fear lives. Being forgetful can be worrying, but as Devon Partnership NHS Trust points out, while memory loss can sometimes be a symptom of dementia, “this often isn’t the case”. Memory difficulties can be caused by a number of other issues, including:
- Anxiety, stress or depression
- Physical causes such as a head injury or a stroke
- Vitamin B12 deficiency and thyroid problems
- Some medicines, which can affect memory and concentration
The last category is worth emphasising. If you take regular medication, it’s worth reviewing what you take with your GP, because memory and concentration issues can be a side effect. As the NHS notes, it’s worth getting checked, because any treatment you need may work better if it’s started early [S1].
Lifestyle factors matter too. Getting good-quality rest is a sensible habit, and our guide to sleep hygiene and what the NHS says about resting better covers practical steps.

When to worry about memory loss: the signs that warrant a GP visit
The NHS advice is refreshingly straightforward: most people forget things from time to time, but see a GP if you keep having problems with your memory. Specifically, seek help if memory problems are affecting your day-to-day life. It’s often nothing serious, but it’s best to get checked, because any treatment you need may work better if it’s started early.
What happens at the appointment
Knowing what to expect can make the step feel less daunting:
- The GP will ask questions to try to find the cause, talk about your experiences and family history, and may request a blood test.
- They may do a memory test and a physical examination, and blood tests may be used to check whether another condition is causing symptoms.
- If other causes are ruled out, the GP may refer you to a memory specialist or memory clinic for an in-depth assessment; further tests such as scans may sometimes be needed.
- Treatment depends on the cause — which is precisely why self-diagnosis isn’t advised.
One practical tip from the NHS: it can be useful to bring someone else with you who can help describe the problems you’re having. Family members often notice changes before we do ourselves.
Worried about an older relative? How to raise the subject
If someone you know is becoming increasingly forgetful, the NHS encourages gently suggesting they see a GP to talk about the early signs of dementia. Memory loss is one of the main signs of dementia, but it isn’t the only one. Other signs include:
- Increasing difficulty with tasks and activities that require concentration and planning
- Difficulty finding the right words, or not being able to follow conversations as easily
You might offer to go along with them — both to support them and to help recall what was discussed. The NHS notes that although dementia is not only about memory loss, if it is found early, its progress can be slowed down in some cases, so the person may be able to maintain their mental function for longer. That’s a genuine, practical reason not to put off a conversation out of awkwardness.
Charities such as the Alzheimer’s Society provide specialist support for people living with dementia and their families, as Devon Partnership NHS Trust notes. And if you’re in crisis, NHS 111 (select the mental health option) is the route to urgent help.
Do memory supplements work? How to read the claims critically
Worries about memory have created a huge market for brain health supplements, and the marketing can be dramatic. It’s worth developing a few habits of healthy scepticism before spending money — our skeptic’s buying guide to brain health supplements goes into this in depth.
Red flags in supplement marketing
- Unestablished scientific concepts. If a product’s central story rests on a term you can’t find in reputable health sources, treat it as marketing, not science. If a product’s central story rests on a term you can’t find in reputable health sources — such as the NHS or the WHO — treat it as marketing, not science.
- Disease claims. A supplement must never be described as preventing, treating or curing a disease, including dementia or memory decline. Any seller implying otherwise should be treated with caution.
- Missing evidence. Independent evidence for many supplement ingredients is limited, weak or drawn from studies that don’t reflect how the product is actually sold. If a seller can’t point to robust research, that absence of evidence is itself information.
- Promises of certain results. According to the NHS, treatment for memory problems depends on their cause, and it’s best to see a GP rather than self-diagnose [S1]. According to the NHS, treatment for memory problems depends on their cause, and it’s best to see a GP rather than self-diagnose [S1].
An honest look at Phytomem One
Because readers ask about products like this, here is what can fairly be said. Some supplements of this kind are marketed by their sellers as memory supplements, with sellers suggesting they may support memory. Those are the seller’s claims, reported as claims — and, plainly, the seller’s marketing language does not correspond to concepts recognised by independent health authorities, and robust independent evidence for such claims appears to be lacking.
That doesn’t automatically make it unsafe — but it does mean you should weigh it accordingly:
- It may suit: adults who understand it’s a supplement, not a treatment, and who want to try it with realistic expectations and, ideally, a pharmacist’s or GP’s sign-off.
- It does not suit: anyone seeking a substitute for medical assessment of memory problems, anyone pregnant or breastfeeding, taking medication, or managing a health condition — all of whom should speak to a GP or pharmacist first.
If you’ve already spoken to a healthcare professional and simply want to explore the product for yourself, you can visit the Phytomem One seller’s page to read their claims directly — ideally with the checklist above in hand. For most people, though, free options come first: good sleep, regular social contact, physical activity, a balanced diet and practical aids such as lists, calendars and routines, which HealthAnswers notes can make day-to-day life easier to manage while keeping the mind active.
What can you do today to support your memory?
Whatever the cause of your lapses, a few practical strategies are widely recommended in UK health guidance:
- Use external aids. Lists, calendars and regular routines reduce the load on your memory and are genuinely recommended, not signs of decline.
- Stay socially engaged. Social contact helps keep the mind active, per HealthAnswers.
- Prioritise sleep. Chronic poor sleep undermines concentration and recall.
- Review your medicines and lifestyle. Bring a full list of what you take to your next GP appointment.
- Don’t self-diagnose. The NHS is explicit on this: always see a GP rather than trying to work out the cause yourself.
FAQ
Is forgetting where I put my keys a sign of dementia?
On its own, almost certainly not. Occasionally misplacing your keys is a normal part of getting older, and mild lapses alone are rarely a sign of disease, according to HealthAnswers. What matters is whether memory problems persist and interfere with daily life — and if they do, see a GP for assessment.
When should I see a GP about memory loss?
The NHS advises seeing a GP if you keep having problems with your memory, or if memory problems are affecting your day-to-day life. It’s often nothing serious, but treatment tends to work better when started early, and the cause may be something treatable such as stress, low B12 or a thyroid problem.
Can stress or anxiety really cause forgetfulness?
Yes. Devon Partnership NHS Trust lists anxiety, stress and depression among the common causes of memory difficulties, alongside physical causes such as head injury or stroke. This is one more reason a professional assessment is worthwhile — the underlying issue may be very treatable.
Are brain health supplements like Phytomem One worth trying?
Be cautious. Seller claims are not the same as established science: some supplement marketing uses striking concepts that are not recognised scientific ideas, and independent evidence for many supplement ingredients is limited. No supplement can be claimed to treat or prevent dementia, and anyone considering one — especially if pregnant, taking medication or managing a condition — should speak to a GP or pharmacist first.
Can dementia be treated if it’s caught early?
According to the NHS, if dementia is found early, its progress can be slowed down in some cases, so the person may be able to maintain their mental function for longer. Early diagnosis also helps with planning ahead. A GP may carry out a memory test, physical examination and blood tests, and can refer to a memory clinic for further assessment.
The bottom line
Forgetfulness is usually far less frightening than it feels in the moment. Occasional lapses are normal; persistent ones that affect daily life deserve a GP visit — not because the news is likely to be bad, but because the cause is often treatable and early attention always helps. Skip the self-diagnosis, be sceptical of dramatic supplement marketing, lean on free strategies like routines, sleep and social contact, and if you’d like a second opinion on a product before buying it, your local pharmacist is an excellent place to start.
