Focus & Memory

How to Improve Focus and Memory: A Starting Guide

This page is about the habits that help you pay attention and remember in everyday life: sleep, routines, fewer interruptions, planned breaks and checking for health causes. Small, steady changes help most people, and some changes in thinking need a doctor rather than a hack.

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

Start here

  • Work out which problem you have: trouble starting or keeping attention, or trouble remembering. The best first steps differ, and the narrower pages linked below cover each.
  • Protect your sleep first. A good night's sleep helps you learn, make new memories and pay attention, and even one short night can hurt sustained attention.
  • Use outside memory (a calendar, lists, one place for keys and phone) and cut interruptions while you work.

Be careful with

  • Natural does not mean safe. Ginkgo, bacopa, lion's mane and other memory supplements have limited or mixed evidence, and some can interact with medicines.
  • Brain-training games mostly improve the trained game. Do not expect them to sharpen everyday life, and be sceptical of ads that promise otherwise.
  • Do not stop or change a prescribed medicine because you think it affects your concentration. Talk to the prescriber.

Get help when

  • Sudden confusion, a sudden change in memory, or confusion with a severe headache, weakness or trouble speaking needs urgent care now.
  • Memory problems that keep happening or get in the way of daily life, or a change that is getting worse over weeks or months.
  • Trouble concentrating together with low mood, constant worry, extreme tiredness, a cold-intolerant or sluggish feeling, or after starting a new medicine.
  • Lifelong trouble with attention that affects work or relationships may be worth discussing with a doctor (see the ADHD in adults page).

About How to Improve Focus and Memory: A Starting Guide

What this goal means

This is the overall starting point for concentration and memory: being able to start a task, stay with it, and remember what you need. 'Focus' and 'memory' are different things, so the best first steps depend on which one is giving you trouble. Trouble starting or sustaining attention, getting distracted or feeling foggy points to one set of causes; forgetting recent conversations or where things are points to another.

Narrower questions have their own pages (staying focused for longer, distractions, mental clarity, brain fog, everyday memory, remembering tasks, learning, study habits and long-term brain health). They are linked at the bottom so this page does not repeat them.

1

Common experiences

People describe drifting off while reading, losing the thread of a task after an interruption, walking into a room and forgetting why, or forgetting a name or where they put their keys. Occasional lapses like these are common, and the National Institute on Aging describes some forgetfulness as part of normal ageing.

1

Common contributing factors

The usual suspects are short or poor sleep, constant interruptions and heavy multitasking, stress, anxiety or low mood, and some medicines. Medical causes include an underactive thyroid and vitamin B12 deficiency. In adults, ADHD is another possibility.

A study of media multitaskers found they were more easily distracted by irrelevant information, but that kind of study shows association, not cause.

2,3,4,5,6,7

Conditions that can affect thinking

Trouble concentrating can come from sleep problems, anxiety, depression, an underactive thyroid, B12 deficiency and some medicines. This page cannot tell you which applies to you; a doctor can. Memory loss with progressive change is a medical question, covered on its own pages.

5,6,7

Realistic expectations

Expect modest gains from steady habits over weeks, not a sudden jump. Most trial evidence is short and measures lab tasks such as reaction time or word recall, which do not always carry over to daily life. No supplement has been proven to prevent dementia, and the NIA calls the evidence for exercise preventing decline 'encouraging but inconclusive'.

8,9

Who this applies to

Adults with ordinary, everyday concentration or memory slips: students, workers, carers and older adults without a diagnosis. If you have a diagnosed condition, follow your care team's advice first. Children and teenagers should be seen by a doctor or school team; this page is written for adults.

Related conditions and symptoms

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

  • Week 1: note your sleep and wake times and when concentration is best and worst. Change nothing yet.
  • Weeks 2 to 3: fix a regular sleep window, keep caffeine to the morning and early afternoon, and set up one calendar and one list.
  • Silence notifications and work in focused blocks with short planned breaks.
  • Add regular movement, social contact and meals at steady times.

Optional additions

  • After reading something new, close it and recall what you can.
  • Try a timer such as 24 minutes of work and a 6 minute break.
  • Cut back alcohol.

What to track

  • Sleep and wake times.
  • A 0 to 10 rating of concentration at three points in the day.
  • Caffeine and alcohol.
  • What you changed, and how you feel after two to four weeks.

When to reassess

Give each change two to four weeks. If you are not improving, or things are getting worse, book a check-up instead of adding products. If your main problem is staying with a task, distractions, clarity, fog, everyday memory, tasks, learning or studying, move to the narrower goal page.

When to seek professional support

  • See a doctor if problems keep happening or affect daily life.
  • Seek urgent care for sudden confusion or fast-changing thinking.
  • Tell your pharmacist about every supplement and medicine you take.

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

Protect your sleep

High certainty

Addresses: Supports attention and learning

Why it may help: The NIA says a good night's sleep helps you learn, create new memories and pay attention, and that adults need about seven to nine hours. A meta-analysis of 44 studies found that one night of restricted sleep impaired sustained attention.

How to apply it: Keep regular sleep and wake times and treat a short night as a reason for extra care with important tasks the next day.

Who it may suit: Almost everyone.

Precautions: If you snore loudly with breathing pauses or stay foggy after a full night, ask about sleep apnoea.

10,2

Use outside memory: routines, lists, calendars

Moderate certainty

Addresses: Fewer slips with everyday tasks

Why it may help: The NIA suggests a daily routine, to-do lists, calendars and notes, and keeping keys, phone and glasses in the same place.

How to apply it: Choose one calendar and one list and use them every day. Give keys, phone and glasses a fixed home.

Who it may suit: Anyone who forgets appointments, tasks or where things are.

Precautions: These tools help everyday forgetfulness; they do not replace an assessment if memory problems are growing.

1

Cut interruptions while you work

Low certainty

Addresses: Easier to hold a thought

Why it may help: Heavy media multitaskers were more easily distracted by irrelevant information in one study. That kind of study shows association, not cause, but reducing interruptions is a low-risk step.

How to apply it: Work in one tab or app at a time, silence notifications for a set period, and keep your phone out of reach.

Who it may suit: People who switch between messages and tasks all day.

Precautions: The evidence for this habit is associative; try it for a couple of weeks and see.

3

Additional options

Plan short breaks

Low certainty

Addresses: Mood benefit with similar work done

Why it may help: A study of students found planned breaks (24 minutes of study, 6 of break) gave mood benefits and similar task completion compared with choosing break times yourself.

How to apply it: Try a timer: work for a block, then take a short real break away from screens.

Who it may suit: Students and desk workers.

Precautions: One study of students; results may not fit everyone. If you lose a block of work to a break, adjust the length.

11

Test yourself instead of re-reading

Moderate certainty

Addresses: Better recall after days

Why it may help: In laboratory experiments, students who practised recall remembered more after two days and a week than students who re-read the material.

How to apply it: After reading, close the page and write down or say what you remember, then check.

Who it may suit: Anyone learning something new.

Precautions: Short lab experiments with students; the benefit in long courses is covered on the learning pages.

12

Look after mood and stress

Moderate certainty

Addresses: Fewer thinking problems from a treatable cause

Why it may help: The NHS says stress, anxiety and depression can cause memory loss, and these are often treatable.

How to apply it: Notice if worry or low mood arrived around the time your thinking changed, and talk to a doctor about it.

Who it may suit: Anyone whose concentration changed along with mood or stress.

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

4

Move, connect and eat regularly

Mixed findings

Addresses: General brain-healthy lifestyle

Why it may help: The NIA includes exercise, eating well, spending time with friends and family and limiting alcohol among its tips for memory. The NIA calls the evidence for exercise preventing decline 'encouraging but inconclusive', and a 2015 Cochrane review found no cognitive benefit from aerobic exercise in healthy older adults.

How to apply it: Pick activities you enjoy and keep them going. Treat them as good for health in general, with any thinking benefit as a bonus.

Who it may suit: Most adults.

Precautions: Check with a doctor before starting vigorous exercise if you have a heart or other long-term condition.

1,8,13

Still being studied

Caffeine for alertness

Moderate certainty

Addresses: Short-term attention

Why it may help: A review of plant-derived substances concluded caffeine enhances attention and executive functions. The FDA says caffeine can be part of a healthy diet for most people but too much can have negative effects and sensitivity varies.

How to apply it: If it suits you, use it earlier in the day so it does not cost you sleep.

Who it may suit: Adults who already drink coffee or tea and tolerate it.

Precautions: It can disturb sleep, which hurts concentration the next day. Be careful in pregnancy, with anxiety, palpitations or some medicines.

14,15

Brain-training games

Mixed findings

Addresses: Better at the trained game

Why it may help: A review concluded that gains from brain-training tend to stay with the trained task. A meta-analysis of cognitive training found effects that differ by training type.

How to apply it: If you enjoy puzzles, fine, but do not rely on them. Habits like sleep matter more.

Who it may suit: People who enjoy puzzles.

Precautions: Treat claims of big everyday improvements with caution.

9,16

Food & nutrition

Regular meals and plenty of fluid

The NIA includes eating well among its tips for memory and thinking. No single food has been shown to sharpen concentration, so the aim is steady, ordinary eating and not skipping meals when you need to work.

  • Eat at fairly regular times rather than long gaps.
  • Keep a drink beside you while you work.
  • Include fruit, vegetables, wholegrains and fish or other proteins as part of a varied pattern.
1

Caffeine in coffee and tea

A review concluded caffeine enhances attention and executive functions. The FDA says it can be part of a healthy diet for most people, but too much can have negative effects and sensitivity varies. Keep it away from bedtime so it does not cost you sleep.

  • Notice how you feel after your usual amount.
  • Use it earlier in the day.
  • Count energy drinks and supplements too.
14,15

What about 'brain foods'?

Detailed food-by-food evidence for long-term brain health is on the foods for brain health and brain-healthy habits pages. This page does not claim that any food fixes concentration.

  • Look to the foods-for-brain-health page for what research does and does not show.

Remedies & supplements

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

Caffeine (coffee, tea)

Moderate certainty

Studied form and route: Drinks, tablets

Intended outcome: Short-term alertness

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

Traditional use: Coffee and tea are traditional drinks; no specific traditional claim is relied on here.

Laboratory findings: Laboratory findings are not the basis for the claims here.

Limits: Short lab tasks do not show better everyday memory.

Interactions and precautions: Can disturb sleep; sensitivity varies; take care in pregnancy, with anxiety, palpitations or some medicines.

14,17,15

Bacopa (Bacopa monnieri)

Low certainty

Studied form and route: Capsules, extracts

Intended outcome: Possible faster attention-test times

Human evidence: A meta-analysis of 9 trials (518 people, 12 weeks or more) found shorter times on two attention tests.

Traditional use: Used in traditional Ayurvedic medicine for memory.

Laboratory findings: Not the basis for claims here.

Limits: Trials differ in extract and length; effects were modest and on lab tests.

Interactions and precautions: Can interact with medicines and has limited safety data; ask a pharmacist, and avoid in pregnancy and breastfeeding unless advised.

18,19

Ginkgo (Ginkgo biloba)

Not enough evidence

Studied form and route: Capsules, extracts

Intended outcome: No clear benefit

Human evidence: A large trial in 3,069 adults aged 75 and older found no reduction in dementia. A 2026 Cochrane review found it probably has little or no effect on cognition in mild cognitive impairment.

Traditional use: Long used in traditional medicine.

Laboratory findings: Not the basis for claims here.

Limits: The trials were in older people and people with impairment, not ordinary concentration problems.

Interactions and precautions: Can cause headache, stomach upset or dizziness, and some data suggest it can raise bleeding risk. Ask a pharmacist, especially with blood thinners.

20,21,19

Creatine

Low certainty

Studied form and route: Powder, capsules

Intended outcome: Possible small memory improvement

Human evidence: A meta-analysis of 8 trials found a small memory improvement versus placebo, strongest in adults aged 66 to 76.

Traditional use: No traditional use is relied on.

Laboratory findings: Not the basis for claims here.

Limits: Short trials on memory tests; not a focus remedy.

Interactions and precautions: Talk to a doctor first if you have kidney problems or take regular medicines.

22

Therapies & care

Persistent or worsening concentration or memory problems start with a conversation with a GP or other health professional, who can ask about sleep, mood, medicines and other symptoms and arrange checks. This page does not recommend or dose any medicine, and you should never stop a prescribed medicine without advice from the prescriber.

A check-up for lasting concentration or memory problems

High certainty

Professional assessment The NHS says to see a doctor if memory problems keep happening or affect daily life. Sleep problems, anxiety, depression, an underactive thyroid, B12 deficiency and some medicines can all affect concentration, and a doctor can look for them.

Who it may suit: Anyone whose concentration or memory is lasting, worsening or interfering with daily life.

Precautions: Bring a list of your medicines and supplements and examples of what you notice. Sudden confusion needs urgent care.

4,5,6,7

Sleep assessment

Moderate certainty

Professional assessment If you stay foggy after a full night, snore loudly or stop breathing in your sleep, a sleep problem may be involved and a clinician can assess it.

Who it may suit: People with loud snoring, pauses in breathing or unrefreshing sleep.

Precautions: Do not self-treat with sleep aids before an assessment.

10

Assessment for adult ADHD

Moderate certainty

Professional assessment If attention problems have been lifelong and affect work or relationships, ADHD in adults is something a doctor can discuss and assess.

Who it may suit: Adults with lifelong, impairing attention difficulties.

Precautions: This page cannot diagnose ADHD or any other condition.

23

Support for stress, anxiety or low mood

Moderate certainty

Professional support Because stress, anxiety and depression can cause memory loss and are often treatable, talking therapies and medical support are options to discuss with a doctor.

Who it may suit: People whose concentration changed alongside worry or low mood.

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

4

Hearing check

Mixed findings

Professional assessment In the ACHIEVE trial, hearing aids did not reduce three-year cognitive decline overall in older adults with hearing loss, but hearing problems can make conversation hard to follow, so a check is reasonable.

Who it may suit: People who struggle to follow conversations.

Precautions: Do not expect a hearing aid to prevent memory decline on its own.

24

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

Cutting sleep to fit more in

High certainty

Why: One night of restricted sleep impaired sustained attention in a meta-analysis of 44 studies, and the NIA says sleep helps you pay attention and learn.

Who it applies to: Anyone.

Try instead: Protect a regular sleep window first.

10,2

Keeping a phone and message alerts beside you while working

Low certainty

Why: Heavy media multitaskers were more easily distracted by irrelevant information in one study (association, not proof of cause).

Who it applies to: Anyone who works on a screen.

Try instead: Put the phone away for set blocks.

3

Personal triggers to check

Caffeine late in the day

Moderate certainty

Why: Caffeine can improve alertness, but too much has negative effects and it can disturb sleep, which lowers next-day attention.

Who it applies to: Caffeine-sensitive people and poor sleepers.

Try instead: Keep caffeine to the morning and early afternoon.

15,14

Alcohol

Moderate certainty

Why: The NIA lists limiting alcohol among its tips for memory.

Who it applies to: Anyone with memory slips.

Try instead: Cut back, and avoid it when you need a clear head.

1

Unaddressed stress, worry or low mood

Moderate certainty

Why: The NHS says stress, anxiety and depression can cause memory loss, often treatable.

Who it applies to: People whose thinking changed with their mood.

Try instead: Get support rather than just pushing through.

4

Some medicines

Low certainty

Why: Concentration and memory can be affected by some medicines. This page does not name medicines or advise stopping any.

Who it applies to: People who noticed a change after starting a new medicine.

Try instead: Ask the prescriber or a pharmacist; never stop a prescribed medicine on your own.

5,25

Products that need caution

Memory supplements sold as proven

Not enough evidence

Why: The NCCIH summary and NIA state that no supplement has been proven to prevent dementia, and evidence for focus and memory is limited. The NIA warns such products can be unsafe, a waste of money, or interfere with treatment.

Who it applies to: Anyone tempted by 'brain booster' ads.

Try instead: Fix sleep, mood and interruptions first; if you still want to try one, ask a pharmacist.

8,19

Brain-training apps that promise everyday gains

Mixed findings

Why: Gains tend to stay with the trained task, and the evidence for daily life is limited.

Who it applies to: Anyone paying for these apps.

Try instead: Spend the time on sleep, activity and real-world practice.

9

Unsupported claims

'This pill will sharpen your memory or prevent Alzheimer's'

Evidence against

Why: No supplement has been proven to prevent dementia; supplements can interact with medicines.

Who it applies to: Anyone shopping for memory products.

Try instead: Check with a doctor or pharmacist before trying any pill.

8,19

Common mistakes

Assuming it is only 'getting older'

High certainty

Why: The NHS advises seeing a doctor if memory problems keep happening or affect daily life, and sudden confusion needs urgent care.

Who it applies to: Adults noticing change.

Try instead: Book a check rather than waiting.

4

Trying everything at once

Low certainty

Why: Changing many things makes it impossible to tell what helped.

Who it applies to: Anyone starting a new routine.

Try instead: Change one thing for two to four weeks, then add the next.

1

Treating a lasting change as a focus problem

Moderate certainty

Why: Persistent difficulty may come from sleep disorders, mood, thyroid or B12 problems, medicines or ADHD, and a checkup can find these.

Who it applies to: Anyone not improving after several weeks.

Try instead: See a doctor if habit changes do not help.

5,6,7

Evidence & safety

What the research shows

The best-supported steps are the unglamorous ones: enough sleep, outside memory tools, fewer interruptions and checking for health, mood and medicine causes. Study-method evidence (self-testing, planned breaks) is promising but comes from short experiments with students. Exercise and hearing treatment are mixed for preventing decline, brain-training games tend to improve only the trained task, and memory supplements have limited or insufficient evidence for focus and memory.

Limits of the evidence

  • Many trials are short and measure lab tasks such as reaction time or word recall, not daily life.
  • The self-testing and planned-break studies were in students.
  • The media-multitasking study shows association, not cause.
  • Supplement trials differ in product, amount and population; several are small.
  • This page was built from health-agency pages and PubMed abstracts; full texts of trials were not reviewed.

Precautions and interactions

  • Natural does not always mean safe. Check supplements with a pharmacist or doctor if you take any medicine.
  • Pregnancy, breastfeeding, older age and long-term illness change what is advisable for caffeine, exercise and supplements.
  • Never stop a prescribed medicine because of concentration or memory problems without speaking to the prescriber.

Life-stage considerations

  • Pregnancy and breastfeeding: limit caffeine as advised and check any supplement first.
  • Older adults: new or worsening memory problems need evaluation, and medicines can contribute.
  • Children and teenagers: ask a doctor or school team; this page is written for adults.

Warning signs

  • Sudden confusion or a sudden change in memory or thinking.
  • Memory problems that keep happening or affect daily life.
  • Trouble concentrating with low mood, worry, extreme tiredness or after starting a medicine.
  • Confusion with severe headache, weakness, or trouble speaking: urgent care now.

Questions people ask

How can I improve my concentration?

Start with sleep, fewer interruptions, planned breaks and checking for medicine, mood or health causes.

How can I improve my memory?

Use routines, calendars and notes, stay active and socially connected, and sleep well.

Do brain games make me smarter?

They improve performance on the trained tasks; evidence for everyday benefit is limited.

Is a supplement worth trying?

Evidence is limited, and supplements can interact with medicines. Ask a pharmacist first; no supplement has been proven to prevent dementia.

Does caffeine help me focus?

A review concluded caffeine enhances attention and executive functions, but too much has negative effects and it can disturb sleep.

Does ginkgo improve memory?

In a trial of 3,069 older adults it did not reduce dementia, and a 2026 Cochrane review found little or no effect in mild cognitive impairment.

Can lack of sleep affect concentration?

Yes. A meta-analysis found one night of restricted sleep impaired sustained attention.

When is poor concentration a sign of something else?

It can come from sleep problems, anxiety, depression, an underactive thyroid, B12 deficiency, some medicines, or in adults ADHD. A doctor can check.

When should I see a doctor about memory?

If memory problems keep happening or affect daily life. Sudden confusion needs urgent care.

Do planned breaks help?

One study of students found planned breaks gave mood benefits and similar task completion, but evidence is limited.
