Forgetfulness and Memory Loss: Normal or Not?

Forgetting a name, a word or where you put your keys is a normal part of life at any age, and a few simple habits can make everyday memory feel more reliable. This page is about ordinary forgetfulness: what is usual, what helps, which common causes can be treated, and when it is time to get checked.

General information, not medical advice. Last updated October 31, 2026. Written by the AlternativeMed editorial team. Not medically reviewed.

Start here

Give everyday things a fixed home: keys, wallet, phone and glasses in the same place each day, and keep a calendar, to-do list or notes where you will see them.
Protect your sleep (about seven to nine hours for adults) and ask yourself whether stress, low mood, worry or alcohol could be part of the picture.
If forgetting is getting in the way of daily life, is getting worse, or other people have noticed it, book a visit with a doctor and bring someone who knows you well.

Be careful with

Do not try to diagnose the cause of memory loss yourself. This page cannot tell you whether your forgetfulness is ordinary or something that needs treatment.
Supplements sold for memory are not a treatment for memory loss or dementia, and some can interact with medicines (for example, ginkgo may raise bleeding risk). Check with a doctor or pharmacist first.
Never stop a prescribed medicine on your own because you suspect it affects your memory. Write down what you notice and ask your doctor or pharmacist to review it.

Get help when

Sudden confusion, or sudden trouble speaking, in yourself or someone else: this is an emergency. Get medical help immediately.
Memory problems that affect daily life, such as asking the same questions again and again, getting lost in familiar places, trouble following a recipe or directions, or forgetting how to use your phone or find your way home.
Memory or thinking that is clearly getting worse over weeks or months, or that other people have noticed before you did.
Not looking after yourself, such as eating poorly, not bathing or behaving unsafely, or feeling low or worried for weeks at a time alongside memory trouble.

About Forgetfulness and Memory Loss: Normal or Not?

What this goal means

This goal is about everyday memory: remembering names, words, where things are, and what you meant to do, and feeling more confident that you can rely on your memory. It is about ordinary forgetfulness, not about diagnosing a memory condition.

It is normal to forget things once in a while at any age. Most of us have forgotten a name, where we put the keys or whether we locked the door.

^1,2

Common experiences

As people get older, some notice they do not remember information as well as they once did or recall it as quickly, and they may occasionally misplace things or forget to pay a bill. The National Institute on Aging (NIA) describes these as signs of mild forgetfulness, not a serious memory problem.

Slower word-finding is also common with age. Older adults may be slower to find words and recall names, have problems with multitasking and have mild decreases in the ability to pay attention. They usually still learn new things, but may need extra time.

^1,3

Usually part of normal ageing, and when to look closer

Often seen with normal ageing: being slower to find words and recall names; problems multitasking; mild decreases in attention; needing extra time to learn something new, but learning it; occasionally misplacing things or forgetting to pay a bill; forgetting something once in a while, at any age.

Reasons to get checked: asking the same questions repeatedly; getting lost in familiar places; trouble following recipes or directions; becoming more confused about time, people and places; not taking care of yourself, such as eating poorly, not bathing or behaving unsafely; forgetting how to use your phone or find your way home.

The second list is not a diagnosis. It is a reason to book an appointment.

^1,3,2

Word-finding difficulty

Slower word-finding is common with age. Having more trouble coming up with words than other people your age can be a sign of mild cognitive impairment, and difficulty finding the right word is also a common early symptom of dementia. If it is getting worse, happening often or affecting conversations, ask about it.

^3,4,5

Contributing factors

Memory loss can sometimes be caused by something common and treatable, such as stress, anxiety, depression or sleeping problems. Other possibilities include sudden confusion caused by a medical condition such as an infection, an underactive thyroid, and side effects of some medicines.

Alcohol can worsen memory loss and make some older people forgetful and confused. Vitamin B12 or folate deficiency can cause memory problems. Memory and concentration decline faster in older adults with hearing loss than in those with normal hearing, according to the NIA. Even short-term sleep loss measurably affects attention, which is the first step in forming a memory.

^{6,7,8,9,10,11,12}

When family or colleagues notice first

Family and friends may notice memory lapses, and the person may worry about them, which can prompt a visit to the doctor. People may also not notice symptoms themselves, and family may not take them seriously for some time. In one NIA example, a man's boss mentioning missed meetings was part of what led to a check-up.

A person who knows you well can come to the appointment and describe the changes.

^4,5,6

Realistic expectations

Habits and treating contributing causes can make daily life easier, but they will not make memory perfect, and no supplement or app has been shown to prevent dementia. Treat memory tools as support for a normal brain, not as a cure.

The usual pattern is that a cause that is found early may be treatable and any treatment may work better if started early. That is the main reason not to wait if you are worried.

^6,13

Who this applies to

Anyone who forgets things occasionally, from busy younger adults to older adults noticing slower recall. It is not a guide for someone who already has a diagnosis of dementia or mild cognitive impairment; those readers should follow their care team and may find the dementia page more useful.

Related goals have their own pages: reminders and appointments, learning and study techniques, concentration, brain fog, and long-term brain health.

A manageable starting plan

An educational starting point, not a personal prescription. Adjust it to your own situation and any advice from your clinician.

Your first actions

Set up fixed spots for keys, wallet, phone and glasses, and keep one calendar and one list that you check at the same time each day.
Aim for about seven to nine hours of sleep and notice how your memory is on short nights.
Make a list of every medicine and supplement you take, and note whether forgetfulness is worse after alcohol, a bad night or a stressful week.
Book a doctor's visit if forgetfulness affects daily life, is getting worse, or others have noticed it.

Optional additions

Learn a new skill or hobby, stay active and spend time with friends and family.
Ask for a hearing test and have your eyes checked.
Try self-testing when you want to remember something: say it back later rather than only re-reading.
If you want to try a supplement, choose a single ingredient, read the evidence first and speak to a pharmacist.

What to track

A few examples of what you forgot, when, and what was going on (sleep, stress, alcohol).
Anything that is getting worse over weeks or months, or that other people mention.
New medicines or supplements and any change in how you think afterwards.

When to reassess

Give habit and sleep changes a few weeks. If forgetting is still affecting daily life, is worsening, or you are worried at any point, see a doctor rather than waiting for the next review.

When to seek professional support

A person who knows you well can come to the appointment and describe the changes.
For sudden confusion, get medical help immediately; do not wait for an appointment.

What helps

Ordered by how well the research supports each step. Evidence strength is shown on every card; precautions sit next to the advice.

Start here

Give everyday things a fixed home and a routine

Low certainty

Addresses: Fewer lost items and fewer moments of "where did I put it?"

Why it may help: The NIA suggests following a daily routine and putting your wallet, keys, phone and glasses in the same place each day. This takes the load off memory by making the right action automatic.

How to apply it: Choose one bowl, hook or tray near the door for keys, wallet, phone and glasses and use it every time, even when you are in a hurry. Keep routines for things like medicines at the same point in your day.

Who it may suit: Anyone who misplaces things, at any age.

Precautions: These are practical tips from health agencies, not tested treatments. They do not treat an underlying cause of memory loss.

Remember Tasks & Appointments →

Use calendars, lists and notes

Low certainty

Addresses: Fewer missed appointments and forgotten tasks

Why it may help: The NIA suggests making to-do lists and using calendars and notes. Writing something down at the moment you think of it means you do not have to hold it in your head.

How to apply it: Keep one calendar and one list rather than many scraps of paper. Check them at the same time each day, for example with your morning drink. Write down names and what you were told after a conversation.

Who it may suit: Most people, especially anyone juggling many commitments.

Precautions: If you are relying on lists to get through ordinary tasks and still missing things, mention it to a doctor.

Remember Tasks & Appointments →

Protect your sleep

Moderate certainty

Addresses: Better attention, learning and recall the next day

Why it may help: The NIA says a good night's sleep can help you learn, create new memories, respond quickly, solve problems and pay attention, and that adults need about seven to nine hours. A meta-analysis found short-term total sleep deprivation had a large effect on lapses in simple attention, and another found that even one night of restricted sleep impaired sustained attention.

How to apply it: Keep a regular sleep and wake time, wind down in the last hour, and see our sleep pages for onset, waking and schedule problems.

Who it may suit: Nearly everyone. Especially useful if forgetfulness is worse after bad nights.

Precautions: Snoring with gasping, or long-standing insomnia, needs a medical check rather than only habit changes; untreated sleep apnea can lead to serious health problems.

^14,11,12

Improve Your Sleep Quality → Sleep and cognitive changes with age →

Look for common, treatable causes

Moderate certainty

Addresses: Finding out whether stress, mood, sleep or health problems are behind the forgetfulness

Why it may help: The NHS says memory loss can sometimes be caused by something common and treatable, such as stress, anxiety, depression or sleeping problems. Other causes doctors consider include infections, an underactive thyroid and side effects of some medicines.

How to apply it: Ask yourself honestly about stress, worry, low mood, sleep and alcohol over the last few weeks. Keep a short note of when forgetting happens and bring it to a doctor with a list of every medicine and supplement you take.

Who it may suit: Anyone whose forgetfulness is new, is getting in the way, or began after a stressful time, illness or change in medicines.

Precautions: Feeling low or worried for weeks at a time, or any thoughts of harming yourself, needs a doctor or crisis service now, not self-help.

^6,7,1

Medicines, sleep, mood and illness that affect memory → Stress vs anxiety, burnout and depression →

Cut back on alcohol

Moderate certainty

Addresses: Less forgetfulness and confusion linked to alcohol

Why it may help: The NIA says alcohol can worsen memory loss and can cause some older people to be forgetful and confused.

How to apply it: Notice whether forgetfulness is worse the day after drinking, and consider drinking less or not at all. Talk to a doctor if cutting down is hard.

Who it may suit: Anyone who drinks regularly, especially older adults.

Precautions: If you drink heavily every day, do not stop suddenly without medical advice because withdrawal can be dangerous.

⁸

Caffeine, alcohol and sleep →

Stay active, social and curious

Low certainty

Addresses: General support for mood, sleep and daily confidence

Why it may help: The NIA suggests learning a new skill, staying active, spending time with others, getting enough sleep and exercising as ways of dealing with forgetfulness. These are good for general health, but they are not proven to prevent memory problems.

How to apply it: Pick activities you enjoy: a walk with a friend, a class, a hobby that is new to you, volunteering. Regular is better than intense.

Who it may suit: Most adults. Check with a doctor before starting a new exercise programme if you have health conditions.

Precautions: A 2015 Cochrane review of 12 trials found no cognitive benefit from aerobic exercise in healthy people over 55, so do not expect exercise alone to improve memory scores. It still helps heart health and mood.

^1,15,13

Maintain Brain Health as You Age →

Additional options

Pay attention when you put something down or meet someone

Low certainty

Addresses: Stronger chance of recalling it later

Why it may help: A memory can only be recalled if it was noticed in the first place. Multitasking and distraction pull attention away: in one study, heavy media multitaskers were more susceptible to interference from irrelevant stimuli.

How to apply it: For the few seconds it takes to put your keys down or hear a name, stop what else you are doing. Repeat the name once in conversation. Put your phone away during important conversations.

Who it may suit: Anyone who says they "never took it in" when they forgot.

Precautions: The multitasking study measured attention tasks in a lab, not everyday memory, so treat this as a sensible habit rather than a proven fix.

^16,3

Manage Distractions →

Test yourself instead of only re-reading

Moderate certainty

Addresses: Better long-term recall of things you want to learn

Why it may help: In two experiments with students, repeated recall tests produced better retention after two days and a week than repeated re-reading, even though re-reading made students feel more confident.

How to apply it: After reading or being told something you want to remember, cover it and try to say it back in your own words, then check. Do it again later, not only straight away.

Who it may suit: Anyone learning names, plans or facts they want to keep.

Precautions: The experiments were with students and prose passages; the same principle is expected to help everyday learning but was not tested here for age-related forgetfulness.

¹⁷

Learn & Retain New Information →

Check your hearing and vision

Low certainty

Addresses: Clearer information going in, which helps recall

Why it may help: The NIA reports that memory and concentration decline faster in older adults with hearing loss than in those with normal hearing. If you mishear a name, you cannot recall it.

How to apply it: If you often ask people to repeat things, or notice you are missing words, ask for a hearing test, and have your eyes checked regularly.

Who it may suit: Older adults, and anyone who struggles to follow conversations in noisy places.

Precautions: A large trial of hearing aids (ACHIEVE) found no overall difference in 3-year cognitive decline, with a possible benefit in higher-risk people, so check hearing for its own sake.

^10,18

Hearing and vision changes →

Review your medicines with a pharmacist or doctor

Low certainty

Addresses: Spotting medicines that may cloud thinking

Why it may help: Harvard Health notes that sleep and pain drugs are common culprits for brain fog, and a large observational study linked higher cumulative use of strong anticholinergic medicines to an increased risk of dementia. Observational studies cannot prove cause and effect.

How to apply it: Make a list of everything you take, including over-the-counter products and supplements, and ask for a review. Track when you take each medicine and what you notice for a week or two.

Who it may suit: Anyone on several medicines, and older adults.

Precautions: Do not stop a prescribed medicine on your own. Doctors may change a dose or timing, or switch a medicine; that decision is theirs and yours together.

^19,20,21

Still being studied

Brain-training games and apps

Low certainty

Addresses: Better scores on the trained tasks, little evidence of wider memory benefit

Why it may help: A review of the brain-training literature found extensive evidence that these programmes improve performance on the trained tasks, but little evidence that training improves distantly related tasks or everyday performance. In the 10-year ACTIVE trial, reasoning and speed training, but not memory training, improved targeted abilities for 10 years.

How to apply it: Enjoy puzzles and games if you like them, but do not expect them to fix everyday forgetfulness. Time is probably better spent on sleep, activity and social contact.

Who it may suit: People who find puzzles enjoyable. Not a substitute for a medical check.

Precautions: The US Federal Trade Commission has settled a case over claims that a popular brain-training programme could delay age-related decline; be wary of such promises.

Brain-friendly eating patterns (Mediterranean-style, MIND)

Mixed findings

Addresses: Possible general brain and heart benefits; not shown to improve memory in a trial

Why it may help: Some observational studies link these diets to lower dementia risk, but a 3-year randomized trial of 604 older adults found no significant difference in cognition or brain MRI between the MIND diet and a control diet. The NIA says there is no evidence that eating or avoiding a specific food prevents age-related decline.

How to apply it: Eat plenty of vegetables, fish, nuts and whole foods because they are good for the heart; treat any memory benefit as a bonus.

Who it may suit: Most adults.

Precautions: Food allergies and medicine-food interactions (for example, some blood thinners and leafy greens) matter; check with your clinician.

^25,26

Food and nutrition for brain health →

Regular physical activity

Mixed findings

Addresses: Good for general health; mixed evidence for memory in healthy adults

Why it may help: The NIA calls the evidence for preventing decline encouraging but inconclusive. A 2015 Cochrane review found no cognitive benefit from aerobic exercise in cognitively healthy people over 55, while the American Academy of Neurology says exercise training (6 months) is likely to improve cognitive measures in people with mild cognitive impairment.

How to apply it: Choose movement you enjoy and can keep up. If you have health conditions, ask a doctor first.

Who it may suit: Most adults.

Precautions: Start gently if you have been inactive, and get advice about heart or joint conditions.

^13,15,27

Food & nutrition

Eating patterns

Some, but not all, observational studies link Mediterranean-style and similar diets to lower dementia risk compared with a Western-style diet. In a 3-year randomized trial of 604 older adults with a family history of dementia, the MIND diet did not differ significantly from a control diet in cognition or brain MRI; both groups improved, so the trial cannot say whether the diet or other factors mattered.

That does not make these diets harmful. They remain reasonable eating patterns for the heart and general health, and foods that are good for blood pressure are sensible choices because high blood pressure is a risk factor for later cognitive problems.

^25,26,3

Individual foods

A diet with regular fish is associated with higher cognitive function and slower decline with age, and one study based on reported eating habits linked a daily serving of leafy greens to slower age-related decline. These are associations, not proof. The NIA says there is no evidence yet that eating or avoiding a specific food can prevent Alzheimer's or age-related cognitive decline.

Fish, especially oily fish, as part of a varied diet
Leafy greens (if you take a blood thinner that interacts with vitamin K, ask your clinician before changing how much you eat)
Nuts, berries and whole foods as general healthy eating

^25,28

Vitamin B12 and folate

Low vitamin B12 or folate can cause memory, understanding and judgement problems, and delays can leave some problems irreversible. If you eat little animal food, are older, or have digestive problems, ask your doctor about testing rather than guessing with supplements.

Foods rich in B12 are covered in our B12 food guide.

⁹

Caffeine and alcohol

Caffeine can be part of a healthy diet for most people. The FDA has cited about 400 mg a day (roughly two to three 12-ounce cups of coffee) as an amount not generally associated with negative effects for most adults, though sensitivity varies, and too much caffeine can disturb sleep, which hurts memory.

Alcohol can worsen memory loss and make some older people forgetful and confused.

^29,8

Remedies & supplements

Traditional use, laboratory findings and human trials are kept apart. "Natural" does not mean safe.

Ginkgo (Ginkgo biloba)

Low certainty

Studied form and route: Leaf extract capsules or tablets

Intended outcome: Memory in older adults and people with mild cognitive impairment

Human evidence: A large trial of 3,069 adults aged 75 and older found ginkgo did not reduce the rate of dementia. A 2026 Cochrane review found it probably has little or no effect on cognition or daily activities in people with mild cognitive impairment. NCCIH found no conclusive evidence that it prevents or slows dementia or cognitive decline.

Traditional use: Ginkgo leaf has a long history of traditional use and is widely marketed for memory.

Limits: Trials were in older adults, so results cannot be assumed for younger people. Product quality varies.

Interactions and precautions: Ginkgo can cause headache, stomach upset, dizziness or allergic skin reactions, and some data suggest it can raise bleeding risk. Do not combine with blood thinners or before surgery without asking a doctor or pharmacist.

^30,31,28

Ginkgo →

Bacopa (Bacopa monnieri)

Low certainty

Studied form and route: Standardised extract capsules taken for at least several weeks

Intended outcome: Attention and memory recall on tests in healthy adults

Human evidence: A meta-analysis of 9 trials (518 people, 12 weeks or more) found shorter times on a trail-making attention test. A systematic review found it improved memory free recall on 9 of 17 tests, with little evidence for other abilities. A 2026 network meta-analysis said the lack of direct comparisons limits the strength of its evidence.

Traditional use: Used traditionally in Ayurvedic practice, where it is known as brahmi.

Limits: Trials used short lab tests, not everyday memory, and were mostly in healthy adults, not people with memory problems.

Interactions and precautions: Product quality varies and not enough interaction research was read for us to call it safe with medicines. Ask a pharmacist, especially if you take regular medicines, are pregnant or breastfeeding, or have a medical condition.

^32,33,34

Bacopa monnieri → Ginkgo vs ginseng vs bacopa →

Lion's mane (Hericium erinaceus)

Not enough evidence

Studied form and route: Mushroom powder, capsules or extracts

Intended outcome: Memory and thinking tests

Human evidence: A 30-person trial in Japanese adults aged 50 to 80 with mild cognitive impairment reported higher scores on one scale while taking it, falling after it stopped. A pilot of 41 young adults found a faster Stroop response one hour after one dose, with some null results, and the authors noted the small sample.

Traditional use: Used as a food and in traditional East Asian practice.

Laboratory findings: Effects on nerve growth factors are lab findings and are not proof of benefit in people.

Limits: Small trials, short follow-up and few outcomes; not enough to recommend for memory.

Interactions and precautions: A systematic review lists stomach discomfort, headache and allergic reactions as possible side effects. Avoid if you have a mushroom allergy; ask a pharmacist about medicines.

^35,36,37

Lion's mane for memory: what trials found → Mushroom safety →

Creatine

Low certainty

Studied form and route: Powder or capsules

Intended outcome: Memory test scores

Human evidence: A meta-analysis of 8 trials found a small memory improvement versus placebo, strongest in adults aged 66 to 76. A 2024 meta-analysis of 16 trials found benefits for memory, attention time and processing speed, but not overall cognition or executive function.

Limits: Small effects on short lab tests; trials mixed healthy people and people with disease.

Interactions and precautions: People with kidney problems, and anyone taking regular medicines, should ask a clinician first. Product quality varies.

^38,39

Creatine → Creatine and cognition: what research shows → Creatine and kidney disease →

Omega-3 capsules (fish oil)

Very low certainty

Studied form and route: Fish oil or algal oil capsules

Intended outcome: Memory in older adults

Human evidence: NCCIH reports that reviews of trials in older people without dementia, and in mild-to-moderate Alzheimer's, found no convincing benefit. A trial of about 4,000 older adults found omega-3 supplements did not slow cognitive decline, according to the NIA.

Limits: Fish in the diet and fish oil pills are different exposures; findings do not transfer.

Interactions and precautions: Can interact with blood thinners; ask a pharmacist. Check with a doctor if you have a fish allergy or a bleeding condition.

^28,25

Omega-3: memory, cognition and dementia trials →

Vitamin B12 and folate (when low)

Mixed findings

Studied form and route: Diet, tablets or injections prescribed after a test

Intended outcome: Correcting a deficiency that can cause memory problems

Human evidence: The NHS says B12 or folate deficiency can cause problems with memory, understanding and judgement and that some problems can be irreversible if untreated. For people who are not deficient, NCCIH reports short-term trials show no cognitive benefit from B vitamins in adults 50 or older, and a longer-trial meta-analysis suggests they might be associated with slowing decline.

Limits: Helps if you are deficient. Evidence in people who are not deficient is mixed.

Interactions and precautions: Test first rather than guess. High-dose vitamin B6 over long periods can damage nerves.

^9,28

Vitamin B12 deficiency → Foods high in vitamin B12 →

Caffeine (coffee, tea)

Moderate certainty

Studied form and route: Coffee, tea or caffeinated drinks

Intended outcome: Short-term alertness and attention

Human evidence: A systematic review of plant-derived substances concluded that caffeine enhances attention and executive functions. A 2025 meta-analysis found small, uncertain differences favouring theanine plus caffeine on some attention and mood tests in the first two hours.

Traditional use: Long-standing everyday use.

Limits: Effects are short-lived and are about alertness more than long-term memory.

Interactions and precautions: The FDA has cited about 400 mg a day as an amount not generally associated with negative effects for most adults, but sensitivity varies. Caffeine late in the day can disturb sleep, which hurts memory. Less is wiser in pregnancy and with anxiety or heart rhythm problems.

Therapies & care

This site focuses on natural approaches, but forgetfulness that affects daily life deserves proper assessment. The descriptions below are general; your own doctor decides what is right for you. Never stop or change a prescribed medicine without talking to your doctor or pharmacist.

A visit to your doctor

Moderate certainty

Primary care assessment A doctor can talk through what has changed, check for common and treatable causes such as infections, an underactive thyroid, low B12 or folate, sleep problems, low mood and anxiety, and review your medicines. They can refer you for a fuller memory assessment if needed.

Who it may suit: Anyone whose memory problems affect daily life, are getting worse, or worry them or their family.

Precautions: Bring a person who knows you, written examples of what has changed and a list of every medicine and supplement.

^6,7

Memory changes: when to get help →

Medicine review

Moderate certainty

Doctor or pharmacist review A review of everything you take, including over-the-counter products, vitamins and herbal remedies. Doctors may switch drugs, change doses or timing, or stop a drug that is no longer needed. The American Academy of Neurology guideline says cognitively impairing medicines should be discontinued where possible in people with mild cognitive impairment.

Who it may suit: People on several medicines, and older adults.

Precautions: Do not stop a medicine on your own.

^19,20,27

Medicines, sleep, mood and illness that affect memory →

Treatment for sleep, low mood or anxiety

Moderate certainty

Professional care for common treatable causes When stress, anxiety, depression or sleeping problems are behind the forgetfulness, treating them can help memory as a result. Talking therapies and other established care exist for each of these; a doctor can explain the options.

Who it may suit: People whose memory slips started alongside poor sleep, worry or low mood.

Precautions: Low mood lasting two weeks or more, loss of interest, or any thoughts of self-harm need a doctor or crisis service now.

^6,7

Therapy for anxiety and stress → Insomnia →

Hearing and vision checks

Mixed findings

Sensory care Hearing loss is linked to faster decline in memory and concentration. A hearing test and, if needed, hearing aids help you take in information. In the ACHIEVE trial hearing aids did not reduce 3-year cognitive decline overall, with a possible benefit in higher-risk people.

Who it may suit: Anyone who often mishears or asks people to repeat things.

Precautions: Treat hearing and vision care as worthwhile in its own right, not as a guaranteed memory fix.

^10,18

Hearing and vision changes →

Cognitive rehabilitation

Low certainty

Structured memory support Some NHS care teams offer activities to improve memory, concentration, thinking and mood (cognitive rehabilitation), for example after long COVID. Structured cognitive training generally improves the trained tasks, with a pooled effect of about 0.28 in a meta-analysis of 215 training studies in healthy ageing and mild cognitive impairment.

Who it may suit: People with persistent problems after illness or with a diagnosed condition, guided by a clinician.

Precautions: Ask your doctor what is available. Consumer brain-training apps are not the same as clinician-led programmes.

What to avoid

Habits, products and claims that can get in the way. Never stop a prescribed medicine without talking to the professional who prescribed it.

Risks that apply to most people

Trying to diagnose yourself

Moderate certainty

Why: The NHS advises against self-diagnosing the cause of memory loss and to see a doctor if it is affecting daily life. The cause may be treatable, and any treatment may work better if started early.

Who it applies to: Anyone who is worried about their memory.

Try instead: Note examples, when they happen and how long, then see a doctor, ideally with a person who knows you well.

^6,7

Memory changes: when to get help →

Waiting it out when daily life is affected

Moderate certainty

Why: Asking the same questions repeatedly, getting lost in familiar places, or forgetting how to use the phone are reasons to get checked, not to wait.

Who it applies to: Anyone, and family members who notice changes in someone else.

Try instead: Book a doctor's appointment and describe the changes.

^1,6

Mild cognitive impairment and dementia →

Assuming it is only age or stress

Moderate certainty

Why: Slower recall is common with age and stress is a common cause, but infections, thyroid problems, B12 or folate deficiency and medicine side effects can also affect memory and are treatable.

Who it applies to: Anyone with new or worsening forgetfulness.

Try instead: Ask a doctor about checks for common causes such as thyroid and vitamin levels, and review of medicines.

^7,9,44

Thyroid and fatigue → Vitamin B12 deficiency →

Heavy or regular drinking

Moderate certainty

Why: The NIA says alcohol can worsen memory loss and cause some older people to be forgetful and confused.

Who it applies to: Anyone who drinks regularly, especially older adults.

Try instead: Drink less or not at all and talk to a doctor if that is hard.

⁸

Caffeine, alcohol and sleep →

Personal triggers to check

Short or poor sleep

High certainty

Why: Meta-analyses found short-term sleep deprivation had a large effect on lapses in simple attention, and one night of restricted sleep impaired sustained attention. Poorly attended information is poorly remembered.

Who it applies to: Anyone with late nights, shift work, insomnia or untreated sleep apnea.

Try instead: Aim for about seven to nine hours and see a doctor about long-standing sleep problems.

^11,12,14

Improve Your Sleep Quality → Sleep apnea →

Stress, worry and low mood

Moderate certainty

Why: The NHS lists stress, anxiety and depression as common, treatable causes of memory loss. We did not find a source that measures how large the effect of stress alone is.

Who it applies to: People going through a stressful period, grief, or long-lasting low mood or anxiety.

Try instead: Address the stress or mood problem itself, talk to a doctor if it lasts, and use lists while it passes.

^6,7

Manage Everyday Stress → Anxiety disorders →

Constant multitasking and interruption

Low certainty

Why: Heavy media multitaskers were more susceptible to interference from irrelevant stimuli in one study. Interrupted attention means fewer things are properly noticed and stored.

Who it applies to: Anyone who often switches between phone, messages and tasks.

Try instead: Do one thing at a time when you need to remember it.

¹⁶

Manage Distractions →

Products that need caution

Memory supplements sold as a cure or prevention for memory loss

Evidence against

Why: The NIA warns people to check with a doctor before trying any pill that promises to prevent Alzheimer's, because such products may be unsafe, a waste of money, or may interfere with prescribed treatment. Nothing has been proven to prevent Alzheimer's, and the NIA recommends no vitamin or supplement for preventing it.

Who it applies to: Anyone tempted by products advertised for memory or "brain health".

Try instead: Spend the money on a medical check, a hearing test or sleep help. See our honest comparison below before choosing a supplement.

^13,25

Nootropics and memory supplements compared →

Nootropic blends and stacks

Not enough evidence

Why: We searched for human trials of commercial blends and found trials only of individual ingredients. Mixed products make it impossible to assign any effect to one ingredient.

Who it applies to: Anyone buying multi-ingredient focus or memory formulas.

Try instead: If you do try a single ingredient, tell your doctor and pharmacist first.

^28,45

Nootropics and medicine interactions →

Brain-training apps sold on dramatic claims

Low certainty

Why: Training improves the trained tasks, with little evidence of wider benefit. The FTC settled with one company over claims about delaying decline and protecting against mild cognitive impairment.

Who it applies to: Anyone paying for an app because of a memory worry.

Try instead: If you enjoy puzzles, treat them as a hobby, not a treatment.

Unsupported claims

"This supplement prevents or reverses memory loss"

Evidence against

Why: No supplement has been proven to prevent Alzheimer's. NCCIH found no conclusive evidence that ginkgo prevents or slows dementia or cognitive decline.

Who it applies to: Marketing for ginkgo, blends, powders and gummies.

Try instead: Ask a doctor about any new or worsening memory problems.

"Forgetting means you will get dementia"

Moderate certainty

Why: Mild forgetfulness is common with age. Serious memory problems make everyday things hard, such as driving, using the phone and finding your way home. Dementia is not a natural part of ageing.

Who it applies to: Anyone worried because of a few slips.

Try instead: Compare what you notice with the lists above, and get checked if you are worried or others have noticed changes.

Common mistakes

Stopping a prescribed medicine because you think it affects memory

Moderate certainty

Why: Medicines can affect thinking, but doctors choose treatment with benefits and risks in mind. Stopping on your own can be harmful.

Who it applies to: Anyone taking prescribed medicines.

Try instead: Track symptoms for a week or two and share them with your doctor or pharmacist, who can review or change the medicine if needed.

Going to the appointment alone with no examples

Low certainty

Why: A doctor needs to know what has changed and how long it has been going on. Family and friends may notice things you do not.

Who it applies to: Anyone booking a memory check.

Try instead: Bring a person who knows you, a few written examples and your list of medicines.

Evidence & safety

What the research shows

Ordinary forgetfulness is common at any age, and slower recall and word-finding are typical with age. Health agencies recommend routines, lists, sleep, activity and social contact, but these are practical tips rather than treatments tested in trials. Common treatable causes such as stress, low mood, sleep problems, alcohol, hearing loss, thyroid problems, B12 or folate deficiency and some medicines are well recognised. Human evidence for memory supplements is limited and mostly negative or uncertain, and nothing has been proven to prevent Alzheimer's disease.

Limits of the evidence

Most supplement and brain-training trials use short lab tests of memory, not everyday life.
Many studies are observational and cannot prove cause and effect.
Trials are often in older adults or in specific groups, so findings may not apply to everyone.
We did not find a source that measures how large the effect of stress alone is on everyday memory.
Doses are not given on this page because they depend on the product and the person.

Precautions and interactions

Check with a doctor or pharmacist before using any memory supplement, especially with blood thinners or other regular medicines.
Never stop a prescribed medicine on your own.
Supplements are not tested like medicines and are not a substitute for a medical check.

Life-stage considerations

Pregnancy and breastfeeding: ask a doctor before using herbal or mushroom supplements; sleep loss and stress often affect memory at this time and usually ease.
Younger adults: forgetfulness often follows sleep loss, stress or distraction; the same causes apply.
Older adults: slower recall is common, but memory problems that affect daily life should be checked, and medicines should be reviewed regularly.

Warning signs

Sudden confusion: get medical help immediately.
Asking the same questions repeatedly, getting lost in familiar places, or trouble following recipes or directions.
Confusion about time, people and places.
Not looking after yourself or behaving unsafely.
Forgetting how to use your phone or find your way home.

Claim checks

Forgetfulness always means dementia

Moderate certainty

No. Mild forgetfulness is common with age and at any age. Serious memory problems make everyday things hard and need a check. Dementia is not a natural part of ageing.

^1,5

Ginkgo improves memory

Evidence against

A large trial found no reduction in dementia, and a 2026 Cochrane review found little or no effect on cognition in mild cognitive impairment.

^30,31

Brain-training games fix everyday memory

Low certainty

They improve the trained tasks, with little evidence of benefit for distantly related tasks or everyday life.

^22,23

Exercise improves memory in healthy older adults

Mixed findings

A Cochrane review found no cognitive benefit from aerobic exercise in healthy people over 55. Exercise is still recommended for heart and general health.

^15,13

Omega-3 capsules protect memory

Very low certainty

Reviews in older people without dementia found no convincing benefit; fish in the diet is a separate question.

^28,25

Re-reading is the best way to remember

Moderate certainty

In student experiments, repeated testing produced better retention at two days and a week than re-reading, even though re-reading felt more confident.

Questions people ask

Is forgetfulness a sign of dementia?

Usually not on its own. Mild forgetfulness is common with age, but serious memory problems make everyday things hard. If you are worried, ask a doctor.

Why am I so forgetful?

Stress, anxiety, depression and poor sleep are common, treatable causes. Alcohol, some medicines, an underactive thyroid, low B12 or folate and hearing loss can also play a part.

Why can't I find the right word?

Slower word-finding is common with age. Persistent or worsening trouble, or trouble that affects conversation, should be checked.

What is the difference between normal forgetting and a problem?

Forgetting a name or misplacing keys now and then is normal. Asking the same questions repeatedly, getting lost in familiar places or struggling with everyday tasks is a reason to get checked.

What should I tell the doctor?

What has changed, how long it has been going on, and examples. Bring a person who knows you and a list of medicines.

Does lack of sleep affect memory?

Yes. Meta-analyses found that short-term sleep loss impairs attention, and the NIA says good sleep helps you learn and form memories.

Do memory supplements work?

Some single ingredients, such as caffeine for alertness and creatine on memory tests, show small short-term effects in some trials. Most evidence is limited, and no supplement has been proven to prevent dementia.

Does ginkgo help memory?

In a trial of 3,069 older adults it did not reduce dementia, and a 2026 Cochrane review found little or no effect on cognition in mild cognitive impairment. It may raise bleeding risk, so ask a pharmacist first.

Can brain games improve my memory?

They improve performance on the games themselves, with little evidence of wider benefit for everyday memory.

When is confusion an emergency?

Sudden confusion needs medical help immediately; it can be caused by an infection or another medical condition.
