Brain Health Guides

COVID brain fog can last for months for some people after the infection itself has passed. If your head feels slow, scattered, or unlike you, the useful next step is to track the pattern and bring the full picture—fog, fatigue, headaches, sleep, mood, and medicines—to a clinician.

Brain fog is a plain-language term for trouble concentrating, finding words, remembering short-term details, organizing thoughts, or keeping up with tasks that once felt easy. It can be frightening, especially when it arrives after a mild case of COVID, but it is a symptom pattern worth assessing rather than a label that tells you the cause on its own.

How long can COVID brain fog and fatigue last?

There is no single recovery clock. Mayo Clinic describes fatigue and brain fog as common problems in people recovering from COVID and notes that post-acute symptoms can last for several months. In one Northwestern study reported by ABC7, 100 people with mild, non-hospitalized COVID who still had symptoms more than six weeks later were followed over six months. Eighty-five percent reported four or more neurological symptoms, including brain fog, headache, dizziness, fatigue, numbness or tingling, and changes in taste or smell.

That study tells you that lingering symptoms can be real even after a mild initial illness. It does not give one deadline for feeling normal again. Your recovery may depend on more than COVID alone, including sleep, stress, mood, other health conditions, and medication effects. The National Institute on Aging lists sleep problems, medication side effects, anxiety, depression, thyroid, kidney, and liver problems among factors that can affect memory and thinking.

Does COVID brain fog mean permanent brain damage?

Brain fog does not automatically mean permanent brain damage. The research has shown that cognitive symptoms can persist, and researchers are still working out why they happen and why recovery differs from person to person. A UCSF research update describes a small study in which people with COVID-associated cognitive changes had higher inflammatory and immune-blood-vessel markers in cerebrospinal fluid, the liquid around the brain and spinal cord. That finding points researchers toward inflammation and immune activity as possible pieces of the puzzle.

What matters for you is whether the change is affecting daily life and whether it is improving, stable, or worsening. The National Institute on Aging advises discussing noticeable memory changes with a doctor, particularly if you are getting lost in familiar places, repeatedly asking the same questions, struggling with directions, or becoming more confused about time, people, or places.

What does a COVID headache feel like, and how long can it last?

Headache was one of the neurological symptoms reported in the six-month Northwestern long-COVID study. People’s headache patterns can differ, so this information does not establish one typical spot on the head or one expected duration. If you are trying to explain yours at a visit, write down where it hurts, when it began, whether it is constant or comes in waves, what else happens with it, and how it changes your ability to work, sleep, read, or exercise.

The material here does not identify a distinct 2026 strain-specific headache pattern. A new or changing headache still deserves the same careful conversation about timing, severity, other symptoms, and your health history.

Can you clear brain fog immediately?

There is no one immediate reset that fits every case of post-COVID brain fog. A practical short-term goal is to reduce the chance that an overloaded day turns into a confusing one: use a written task list, keep appointments and reminders in one place, and break demanding tasks into smaller steps. The National Institute on Aging specifically recommends routines, calendars, notes, keeping essential items in the same place, sleep, activity, and social connection as ways to support day-to-day memory and thinking.

Give your clinician specifics instead of simply saying “brain fog.” For example: “I lose my place while reading,” “I cannot hold a conversation after lunch,” or “I forget why I opened an app.” That makes it easier to discuss what may be contributing and what kind of follow-up makes sense.

Is Tylenol or ibuprofen better for a COVID headache?

There is not one best choice for every person with a COVID-related headache. Your clinician or pharmacist can help you weigh your health history, current medicines, and the headache pattern before you choose an over-the-counter option. Do not start, stop, or change prescribed medicine based on a headache or brain-fog symptom without speaking with the clinician who manages it.

What research can—and cannot—tell you right now

The strongest practical message from the available research is that persistent cognitive symptoms and fatigue after COVID have been documented in people who were not hospitalized. The Northwestern study included 100 participants across the United States who had mild initial illness and ongoing symptoms after six weeks; it was followed over six months. The UCSF work described above was small, so it helps guide research into possible biology rather than supplying a personal forecast.

It also helps to separate a symptom from a sales promise. The National Institute on Aging’s cognitive-health guidance notes that no vitamin or supplement is recommended for preventing Alzheimer’s or other forms of cognitive decline. If you are considering a brain-health supplement while dealing with lingering symptoms, see our CogniHoney review and our guide to brain supplement interactions before deciding anything.

Questions to take to your doctor

• Could my brain fog, fatigue, headache, sleep changes, or mood changes have more than one cause?
• Which details in my symptom diary would be most useful for follow-up?
• Could any current medicines or supplements be affecting memory, sleep, or concentration?
• What changes would mean I should seek care sooner?
• Would a cognitive, neurological, sleep, or mental-health assessment help clarify what is going on?

The goal is not to dismiss what you feel or to assume the worst. It is to give your clinician a clear timeline and enough detail to look at the whole picture.

If your focus falls apart after meals, your mind feels wired, or you cannot settle into sleep, food may be one useful piece of the ADHD picture. A steady pattern of protein, high-fiber carbohydrates, fruits and vegetables, and healthy fats can support your overall nutrition; it is not a replacement for ADHD care.

There is no single “ADHD diet,” no food that switches ADHD off, and no credible basis for saying that 90% of ADHD comes from one cause. ADHD is complex and multifactorial: genetic susceptibility appears to interact with social and environmental factors, according to a 2023 nutrition review. The useful question is simpler: can your usual meals make it easier or harder to get through the day?

What should an ADHD food list look like?

Start with ordinary foods that make a complete meal. UCLA Health recommends the same broad pattern for people with ADHD as for everyone else: a balanced, whole-food diet with enough fluids. That matters because your brain needs a reliable supply of energy and nutrients, not a perfect menu.

A workable adult meal might be beans, brown rice, vegetables, and salsa; eggs with whole-grain toast and fruit; or salmon, potatoes, and greens. For a child, the same idea can be made smaller and more familiar: an egg wrap with fruit, yogurt with oats and berries, or beans and rice with vegetables. The goal is a repeatable meal, not a restrictive plan.

What does the research actually say about food and ADHD?

The clearest takeaway is not that a particular food fixes ADHD. The 2023 review found that research does not yet support broad recommendations for micronutrients or probiotics in ADHD management. It also found that overall diet quality and symptoms are linked in observational research, but the direction is not settled: ADHD symptoms can make regular, nutritious eating harder as well.

One large Dutch study followed 3,680 school-age children. More ADHD symptoms at age 6 were linked with lower diet quality at age 8, while diet quality at age 8 was not linked with symptoms at age 10. That is a helpful reminder not to blame yourself or a child’s meals for ADHD.

Diet patterns are still worth discussing because they are practical. A review and meta-analysis of six dietary-pattern studies involving 8,816 people found that a pattern higher in vegetables, fruits, seafood, polyunsaturated fats, magnesium, zinc, and plant compounds was associated with lower ADHD risk, while highly processed “western” and “junk food” patterns were associated with higher risk. Those findings describe patterns in groups; they do not tell you that one food will change your symptoms.

Which foods and drinks may make the day easier?

Water is the simplest drink to put first. UCLA Health advises staying hydrated as part of a balanced eating pattern. For children, Humber NHS suggests 6 to 8 glasses of fluid a day and notes that a visible water bottle can make this easier to track.

For meals, pairing a carbohydrate with protein is a practical way to avoid relying on sweets or refined snacks when you are already hungry. Try oatmeal with yogurt, an apple with nut butter, a bean-and-vegetable bowl, or a whole-grain sandwich with eggs or fish. These are meal ideas, not a prescription.

Fish can be a food-first way to include omega-3 fats. The NIH lists salmon, mackerel, tuna, herring, and sardines among food sources of EPA and DHA; flaxseed, chia, walnuts, and plant oils provide ALA. Research on omega-3 supplements and ADHD symptoms is mixed. Across trials, some results were positive and others were not, so food choices and supplements should not be treated as the same decision.

What might be worth limiting?

You do not need to declare common foods “bad.” It can be more useful to notice whether certain choices leave you shaky, hungry again quickly, unable to sleep, or more scattered. UCLA Health highlights refined simple carbohydrates, foods high in additives, unhealthy fats, and caffeine as common areas to consider.

Added sugar does not cause ADHD. The nutrition review describes research on sugar and ADHD as mixed, including a Brazilian cohort that found no association between high versus low sucrose intake from ages 6 to 11 and ADHD incidence. Still, less sugar and fewer highly processed foods can make room for more nourishing options.

What about vitamins, minerals, and supplements?

Iron, zinc, magnesium, vitamin D, and omega-3 fats come up often because they help support normal brain function. The evidence is uneven, and a low level of a nutrient is not the same thing as a reason to take a supplement.

For example, a meta-analysis of 22 studies including 1,280 people with ADHD and 1,200 controls found no statistically significant overall difference in hair or blood zinc levels. A review of six zinc trials in 489 children ages 7 to 10 found an effect on total ADHD scores but not separately on hyperactivity or inattention; certainty ranged from moderate to very low, and most trials were in populations with more zinc deficiency.

Magnesium research is also early. In one placebo-controlled study, 66 children received magnesium plus vitamin D for 8 weeks, and the intervention group had lower conduct, emotional, peer, and total-difficulty scores than the placebo group. That combined study cannot tell you what magnesium alone would do. Vitamin D trials have shown small changes in some ADHD scores, but the review rates the evidence low to very low quality.

If you are considering a supplement, use the decision as a reason to ask about your diet, medications, and whether a deficiency should be checked. The stimulant interactions guide explains why supplement and medication questions deserve a careful look, while focus and attention research separates ingredient discussion from product marketing.

Can an elimination diet identify food triggers?

A few-foods diet is a short, highly restricted process that removes many foods and then adds them back one at a time to identify individual triggers. The 2023 review reports that some children who respond to this approach show better behavior or cognitive functioning after several weeks, but it is not a general-purpose ADHD menu.

In one open-label study of eight children ages 8 to 14, five had more than a 40% improvement on an ADHD rating scale after four weeks of eliminating commonly suspected foods. The study was very small and did not have a control group. In practice, a restrictive plan is a question for a clinician or dietitian, particularly for a growing child, because adequate nutrition still has to come first.

What else can make ADHD feel worse?

Food is only one part of daily function. Poor sleep, irregular meals, medication effects, anxiety, depression, alcohol or drug misuse, and stressful life events can all affect concentration or memory. The National Institute on Aging notes that sleep problems, medication side effects, anxiety, depression, and low levels of nutrients such as vitamin B12 can contribute to memory problems. If a foggy head, flat mood, anxiety, or sleep problem is new, marked, or getting in the way of daily life, bring the whole picture to a clinician rather than assuming food is the cause.

Sleep often deserves attention before you overhaul your pantry. Our sleep and mental health guide covers the habits, evidence, and limits around that connection. For a broader view of food, routines, and non-medication supports, see ADHD management beyond medication.

Before you change your diet, what should you ask?

• Could a regular meal and snack rhythm fit your work, school, or family schedule better than a strict diet?
• Are appetite changes, sleep trouble, caffeine, or medication timing affecting how and when you eat?
• If you are considering iron, zinc, magnesium, vitamin D, or omega-3 supplements, is there a reason to assess diet, medication interactions, or nutrient status first?
• For a child, would a restrictive or elimination approach risk making meals too limited, and who can help guide it?

You do not need a perfect ADHD diet. A realistic next step is to choose a few meals you can repeat, include protein and fiber when you can, keep water close by, and take your specific questions to the clinician who knows your health history.

The natural ways to improve memory with the best support are ordinary ones: exercise regularly, sleep enough, eat a heart-healthy pattern like the Mediterranean or MIND diet, stay mentally and socially active, and use a few memory techniques for the things you need to recall. No single herb, spice or vitamin is a shortcut. Harvard Health says food marketers sometimes exaggerate the benefits of specific foods, so it is better to think in broad patterns.

What are the best natural ways to improve memory?

Harvard Health says proven ways to help protect memory include a healthy diet, regular exercise, not smoking, and keeping blood pressure, cholesterol and blood sugar in check. It adds that a mentally active life matters too: just as muscles grow stronger with use, mental exercise helps keep cognitive skills and memory in tone.

What foods improve memory?

Mass General Brigham's Dr. Rudolph Tanzi recommends several food groups for brain health. If you want three to start with, fatty fish, leafy greens and berries are on the lists from both Mass General Brigham and Harvard Health.

The MIND diet, a Mediterranean-style plan designed for brain health, is heavy on leafy greens, nuts, berries, fish and poultry and avoids red meat, butter, cheese and sweets. Harvard reports that in one study, people who followed it were 30% to 35% less likely to score poorly on cognitive tests.

Healthline reports a 2024 study of 84,000 adults in which an anti-inflammatory diet was linked to a 31% lower dementia risk. It also says a 2025 study of adults aged 50 to 64 found that just 10 days on a high-added-sugar diet hurt memory recall. Tanzi suggests limiting red meat, fried foods, soda and refined carbs.

Is there a drink that helps with memory?

Harvard Health lists tea and coffee among foods that help memory. Mass General Brigham's list of beverages and treats to consider includes coffee, tea (including green tea) and unsweetened fruit juices such as pomegranate juice. It also lists olive oil, seeds and dark chocolate around 70% cacao. Mass General Brigham lists red wine, but Harvard advises drinking alcohol in moderation or avoiding it, so you have no memory reason to start. Skip sugary drinks: Tanzi names soda as a food to limit.

Is there a vitamin, herb or spice that protects memory?

You will see exaggerated claims online about vitamins, memory herbs, and spices. Here is what the medical sources say.

• Vitamins: Harvard says you do need certain vitamins for memory, but studies have not shown that taking more than the recommended daily allowance helps. B vitamins and vitamin D deserve attention because they matter for keeping dementia at bay. A blood test can show whether you are low in B12, and your doctor may then recommend a supplement. Harvard says 10 to 15 minutes of daily sun exposure provides plenty of vitamin D, and a supplement may be called for if that is not possible.
• Herbs: Harvard says ginkgo biloba is often touted as a wonder supplement, but numerous studies have found it has no effect on memory, attention or risk of dementia.
• Single foods and spices: Treat any claim that one food, spice or mix (honey and cinnamon, rosemary, a red spice) can prevent or treat dementia with caution. The better-supported approach is the overall eating pattern above. If you want to add a particular herb or spice to your cooking, that is a food choice, not a treatment. For dementia concerns, see a clinician.

Do memory supplements work?

Mass General Brigham's Dr. Tanzi says the most effective way to get nutrients for brain health is food rather than supplements. He says some supplements might help, but they generally lack clinical data. In his words, “the majority of brain health supplements either contain one ingredient that's not proven to do anything, or multiple ingredients but not enough of any one of them to make a difference.” His advice for now is to ask your doctor.

Healthline notes that if you do not enjoy fatty fish, an omega-3 supplement is one way to reach your daily intake. If you are weighing a specific product, NeuroLift ingredients by version and evidence is the place to read about that product. For a general way to weigh label claims, see Ingredient evidence vs. marketing claims. You can also read about one commonly sold ingredient in our Bacopa monnieri research page.

How does exercise help memory?

Harvard says the brains of people who exercise regularly shrink less with age, especially the hippocampus, and their white matter stays healthier. Swimming, walking and tennis are good choices. Consistency matters more than the activity, so set a regular time. Healthline adds that open-skill exercise, such as team sports where the environment keeps changing, may improve cognition more than closed-skill exercise like hitting golf balls, though that finding comes from one 2019 study of older adults with mild cognitive impairment.

How does sleep affect memory?

Sleep consolidates memories, and too little of it impairs memory and concentration. Harvard also lists sleep deprivation, stress, fatigue and feeling overwhelmed as common contributors to short-term forgetfulness. Stanford's Center for Teaching and Learning suggests 7 to 10 hours of sleep for students. For a way to track your sleep before a doctor visit, see Sleep and Memory: A Simple Record.

What mental exercises improve memory?

Harvard recommends lifelong learning: traveling, learning a language, picking up an instrument, taking art or cooking classes, doing puzzles and playing board games. Healthline reports a 2022 review in which electronic “serious games” may have improved memory in older adults with mild cognitive impairment, but it cautions that the review was small and more high-quality research is needed. Healthline also points out that hands-on puzzles engage the brain differently from screen games, so mixing types is sensible. Mindfulness has been linked to less interference in working memory and better verbal learning.

How can you improve memory and concentration?

Harvard suggests staying organized: keep your keys in one place, put appointments in your phone, keep lists. It also suggests repeating a person's name when you are introduced, paraphrasing conversations, and re-reading carefully. Stanford recommends using reminders and automations to free up working memory, which it says holds roughly 3 to 4 units of information at a time. It also recommends short breaks, since cognitive fatigue impairs working memory, and stress management such as deep breathing.

How do you improve memory for studying?

The Stanford guidance and a University of St. Augustine memory guide describe the same core techniques. If you meet a named “memory trick” online, check whether it uses one of these.

Stanford also suggests mind maps and taking regular breaks, and says to be patient: change takes time.

When is forgetfulness more than normal aging?

Harvard says some memory slowing with age is normal, mostly a slowing of recall rather than loss. See a doctor if you struggle to complete familiar tasks or if forgetfulness disrupts your day. Memory problems can also stem from depression, thyroid problems, vitamin deficiencies, sleep apnea, head injury or medications, and some improve with treatment. Harvard suggests reviewing your prescriptions with your doctor, especially drugs with anticholinergic properties such as older antihistamines (diphenhydramine), some older antidepressants (amitriptyline) and drugs for urinary symptoms (oxybutynin). It also suggests checking hearing, vision, blood pressure, thyroid function and cholesterol. Do not change any medication on your own; ask your clinician. For background on how memory chemistry works, see The Cholinergic System.

Before you buy a memory product

• Ask whether any study tested that exact product at that dose in people, not just one ingredient in animals. A NIH-hosted review of memory enhancement notes that much of the mechanism research comes from animal models and that enhancers can have drawbacks.
• Ask your doctor or pharmacist about interactions with your medicines. See our St. John's wort interaction guide for an example of why this matters.
• A blood test can show whether you are low in B12; discuss suspected deficiencies with your clinician.
• Check whether the plan costs more than free habits such as walking, sleeping and eating fish and greens.

By GlobalMHSummit.com Research Team

Worsening memory has many possible causes, and many are not dementia. Poor sleep, stress, low mood, medication effects, low vitamin B12 and many medical conditions can all make you forgetful. What matters most is whether the change is new for you, getting worse, or getting in the way of daily life. If it is, see a clinician.

What causes memory loss and forgetfulness?

The National Institute on Aging (NIA), part of the U.S. National Institutes of Health, says memory problems can come from factors unrelated to dementia or normal aging. It says these problems usually go away once the condition is successfully treated. Its list is below, alongside other causes named by Cleveland Clinic and Ohio State Health.

Dr. Daniel Cameron, whose clinical blog post covers this question, makes a useful point. Sometimes information was never fully stored because attention was disrupted by fatigue, pain, poor sleep, anxiety or illness. It then feels as though the memory disappeared.

Why is my memory so bad at 20, 25, 30 or 40?

The sources used here give no age-by-age explanation, and none says memory problems are caused by your age in those decades. What they do say applies at any age:

• Harvard Health Publishing says healthy people can experience memory loss or memory distortion at any age. Unless the lapses are extreme and persistent, it says they are not considered indicators of Alzheimer's or other memory-impairing illnesses.
• Dr. Cameron says memory problems can occur at many ages, and that poor sleep, stress, depression, anxiety, medications, vitamin deficiencies, thyroid disease, neurologic disorders and infections can all affect attention and memory. Age is only one part of the evaluation.
• Beyond BookSmart says memory problems are more common among younger adults than you might expect. It describes eight patterns it links to ADHD: difficulty tuning out distractions, brain fog, trouble with scheduling, trouble switching tasks, trouble forming or changing routines, forgetting boring tasks, trouble following instructions in order, and “out of sight, out of mind” misplacing of objects. It also says having several of these does not necessarily mean you have ADHD, and it suggests an ADHD evaluation only if stress, hunger or lack of sleep do not explain things and you notice other ADHD symptoms.

If your struggles began recently, or you can point to a trigger such as a bad stretch of sleep, a new medication or a stressful period, tell a clinician. A pattern like that is useful information.

Is it normal to forget words at 40?

Occasional word-finding trouble is common. The NIA lists “sometimes forgetting which word to use” under normal aging, against “trouble having a conversation” for dementia. Harvard describes “blocking”, the tip-of-the-tongue experience, as the temporary inability to retrieve a memory. It says people retrieve about half of blocked memories within a minute. Harvard also says blocks become more common with age, and links them to trouble remembering other people's names.

None of these sources gives a figure for what is typical at 40. Frequent word-finding trouble that is getting worse is worth raising with a clinician. Cleveland Clinic lists trouble saying or finding the right word (aphasia) as a sign to see a provider when it appears alongside other memory symptoms.

What are the seven types of normal memory problems?

Harvard describes seven ordinary memory flaws. Healthy people can have any of them.

What are the early signs of dementia? Is there a list of 10 warning signs?

The sources used here do not include a ten-item list, so this page does not give one. Here is what they do say.

The NIA says signs that it might be time to talk with a doctor include:

• Asking the same questions over and over
• Getting lost in places you used to know well
• 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

Cleveland Clinic lists asking the same question repeatedly, trouble remembering recent conversations, misplacing commonly used items, missing appointments, and forgetting to pay bills. It advises seeing a provider if these come with trouble finding words, difficulty with tasks you could once do, trouble recognizing faces or familiar items, or trouble with impulse control, planning or concentration. Cleveland Clinic also says progressive memory loss is not just slowed recall: if you can remember with enough time and without hints, it is probably not true memory loss.

The NIA adds that dementia is not a normal part of aging, and that memory loss is not its only sign. People may also have problems with language, visual perception or attention, and some have personality changes. Its comparison of normal aging with dementia:

An Ohio State neurologist says patients with dementia often do not notice their own forgetting, and a family member raises it. Patients who come in worried about their own forgetfulness typically have age-related memory problems and nothing more serious, though tests are still done. That is one clinician's observation, not a rule for your case.

What age does memory loss start?

There is no single age. Ohio State Health‘s neurologist says people typically begin complaining of mild memory issues in their 50s or 60s, and that the risk of dementia or another neurodegenerative disease is higher after 65. Harvard says some memory flaws become more pronounced with age. Memory lapses that come from sleep, stress or other causes can appear at any age, as above.

When should I worry about memory problems?

The NIA says to talk with a doctor if you notice changes in your memory. It adds that memory problems from stress and negative emotions should improve as the stress fades, and that if they persist after a few weeks you should talk with your doctor. Other points where the sources agree:

• Urgent: Cleveland Clinic says sudden memory loss needs immediate medical attention. Dr. Cameron says sudden confusion or cognitive change, especially with weakness, trouble speaking, severe headache, loss of consciousness, seizure or fever, needs urgent assessment.
• Soon: Dr. Cameron says changes deserve prompt attention when they are rapidly worsening, interfere with safety or independence, come with confusion or behavior change, or occur with new neurologic symptoms.
• Routine visit: Cleveland Clinic says you should see a provider if you notice signs of progressive memory loss in yourself or a loved one, because early care can uncover a treatable cause.

It can help to bring a few details. Dr. Cameron suggests thinking about when it started, whether it came on gradually or suddenly, whether it fluctuates, what has become harder, and whether family or coworkers have noticed. He also notes that medications, over-the-counter products and supplements should all be reviewed. A clinician may use cognitive testing, lab studies, a neurologic exam, imaging or referral for neuropsychological assessment, depending on the situation. The NIA suggests a follow-up memory check every six to 12 months for people with memory problems. For a way to track sleep alongside memory, see our guide on sleep and memory records.

What are the types of memory loss?

Cleveland Clinic splits memory loss into two broad kinds. Acute memory loss, commonly called amnesia, happens suddenly because of an illness, injury or other event. Progressive memory loss happens gradually and is sometimes a symptom of a degenerative brain disease. It also describes mild cognitive impairment (MCI), where there are notable changes in memory or other thinking but daily functioning stays the same. The NIA says MCI may be an early sign of Alzheimer's disease, but not everyone with MCI will develop it. Cleveland Clinic names alcohol-related blackouts, head injury, stroke, seizures, mood disorders, migraine, infections and medications among causes of sudden memory loss.

How do I improve my memory?

The sources agree on a few habits. Where the advice is the NIA's or another source's, it is theirs, not this site's.

• Sleep: the NIA says to get enough sleep, generally seven to eight hours a night.
• Move and eat well: the NIA lists exercise, eating well, preventing or controlling high blood pressure, and avoiding or limiting alcohol. Ohio State says physical activity increases circulation and helps reduce inflammation.
• Use memory tools: the NIA suggests routines, to-do lists, calendars, notes, and keeping your wallet, keys, phone and glasses in the same place each day. Cleveland Clinic says using planners and apps does not weaken memory.
• Stay engaged: learning new skills, reading, puzzles, hobbies and time with friends and family are suggested by the NIA, Cleveland Clinic and Ohio State.
• Get help for mood: the NIA says to get help if you feel depressed for weeks at a time.
• Check for a fixable cause: a clinician can review medications, thyroid, B12 and other contributors.

Beyond BookSmart, which sells coaching, says working memory is a skill you can improve with executive function strategies, and it offers its own coaching program. The sources used here do not test that program.

What vitamins help with memory loss? Which vitamin matters most?

Ohio State's neurologist says there is no evidence that any vitamin or herb can prevent memory loss. He says ginseng, vitamin E, coconut oil and omega-3 are harmless at the right dose but not likely to improve memory. He singles out B12: if you are low, raising your level could do a lot to restore memory and clear thinking. The NIA also lists low B12 among factors that can cause memory problems.

The point is to find out whether you are actually low. A clinician can check. Do not start, stop or change any supplement or medication without checking with them first, especially if you take other medicines.

What is the #1 brain supplement?

None of the sources used here ranks supplements, and the Ohio State neurologist says no vitamin or herb has been shown to prevent memory loss. So no product can honestly be called number one on this evidence. If you want to read about a specific product before deciding, our page on NeuroVera reviews, ingredients and price is the place to read about that product. Weigh anything a seller claims against what independent medical sources say, and bring the label to a pharmacist or doctor.

Can memory loss be reversed?

It depends on the cause. Ohio State's neurologist says memory loss that is part of dementia cannot be reversed. If it is related to another issue, such as stroke, concussion, vitamin deficits, stress or uncontrolled medical conditions, he says it can be restored by treating the underlying cause and continuing to stimulate the brain. He also says that if dementia is caught early, medications can slow it, and that if it is caught too late they will not work. Cleveland Clinic says there is currently no way to treat memory loss itself; the main approach is to find and remove the underlying cause where possible. It says progressive memory loss usually is not preventable, though some causes of amnesia are.

What this page cannot tell you

It cannot tell you why your memory has changed. Only a clinician who knows your history, medications and sleep can do that. The sources used here do not give age-specific norms for people in their 20s, 30s or 40s, and they do not name a best supplement. If you are unsure, write down what has changed and when, and take it to an appointment.
