Is this real, or are they selling hope?
- Ask who is selling it. That single question sorts most of what you will be shown. The 10-second bias check.
- "Peer-reviewed" and "published" are not the same thing. Nor is a study with no control group evidence that something works.
- What genuinely lowers risk is free. Blood pressure, hearing, sleep, movement, staying connected.
- If it costs thousands and promises reversal, be slow. The ReCODE programme, costs and evidence in full.
Somewhere around 2am, everyone caring for someone with dementia types the same thing into a search bar: is there anything that helps? What comes back is a wall of pills, drinks, helmets, and "protocols." Here's how to tell the honest from the hopeful, without feeling foolish for looking.
No supplement, drink, or device has been proven to prevent, treat, or cure dementia, and nothing you can buy without a prescription will. (A few prescription drugs can modestly slow early Alzheimer's for some people, worth asking the doctor about, but they aren't cures, aren't for every type, and aren't anything sold online.) That's not despair. It means the things that genuinely help aren't the things being sold to you, and those are further down this page, mostly free.
You don't need to become an expert on every fad. You need one sorting rule that still works on the next product you've never heard of. Here it is, in three buckets.
Steer away
A real risk here, or a regulator has already stepped in.
- "Memory" supplements like Prevagen. A federal court ordered its maker (December 2024) to stop claiming it improves memory or is "clinically proven"; the company is appealing, so treat the memory claim as unproven, and note the company's own study found no benefit. If the best-selling memory pill can't back the promise, be gentle with yourself for having hoped it would.
- Methylene blue (the blue-dye trend). Not proven for dementia, and genuinely dangerous: taken with common antidepressants (SSRIs and others) it can trigger serotonin syndrome, a life-threatening reaction. Not worth the risk.
- Any restrictive diet forced on someone who's losing weight or refusing food. In dementia, keeping weight on and meals pleasant beats any "brain diet." Don't take food they'll eat away from them for a theory.
Being studied, not proven
Interesting, maybe harmless, but don't pay big or pin your hopes on it.
These show up in hopeful headlines. The honest status is the same for all of them: early, short, or mixed studies; no proof it prevents or treats dementia. If it's cheap and safe and you want to try it, that's your call. Just don't let it replace the doctor or the green list below, and don't spend money you need elsewhere.
- Lion's mane · red-light / "photobiomodulation" helmets · hyperbaric oxygen (HBOT) · hydrogen water
- Coconut / MCT oil · curcumin (turmeric) · ginkgo biloba · omega-3 / fish oil · high-dose B vitamins
A few of these interact with medicines (see the caution box). "Being studied" is not "shown to work." It's fine to wait for the answer instead of paying for it now.
The Bredesen protocol (ReCODE) belongs in this bucket too. It is asked about often enough to deserve more than a line. The full picture is below, including what the studies actually show, what it costs by its own published figures, and what's free about it.
Worth your energy
Cheap or free, low-harm, and actually backed by evidence.
None of these are a cure, and none are a guarantee. But they're the steps experts agree genuinely lower risk (for vascular dementia especially, they can buy longer steady stretches), and several also make daily life better right now. Across a whole population, researchers estimate that addressing about 14 everyday factors could delay or prevent up to ~45% of dementia. That is a population estimate, not a personal promise. But it means these are the real levers:
- Treat hearing loss. The single best-evidenced one. In a large trial, hearing aids didn't change much for the average participant, but among older adults already at higher risk, those given hearing aids showed about half as much cognitive decline. That's a population finding about lowering risk, not a promise for any one person, and hearing aids earn their keep anyway by bringing them back into the conversation.
- Treat vision loss. An updated pair of glasses or a cataract fixed keeps them oriented and engaged.
- A daily walk / physical movement. The most consistently protective habit there is, and it burns off restlessness too.
- Blood pressure and cholesterol under control. Especially for vascular dementia, this is brain care as much as heart care. It's the closest thing to "prevention" that exists.
- Stay socially connected. Visits, a day program, a phone call rhythm. Isolation is a risk factor; company is a protection.
- Don't smoke, keep alcohol light, and treat diabetes and depression.
- A Mediterranean-style plate. Vegetables, fish, olive oil, whole grains. Reasonable and heart-healthy; think "worth doing," not "miracle."
The unglamorous truth: the real "recovery story" is blood pressure controlled, sleep fixed, hearing working, the next stroke prevented. Families who do that quietly get some of the longest, steadiest stretches of anyone.
The 10-second bias check
When you can't tell, ask one question: who profits if I believe this? That single test sorts most of the internet. Then scan for the tells. A pitch usually wears several:
- "Clinically proven" with no named study you could actually look up.
- A countdown timer, "only 3 left," or an auto-renewing subscription.
- "Doctors don't want you to know": real science doesn't need a conspiracy.
- Testimonials instead of trials: one moving story where a study should be.
- The words reverse, cure, prevent: the exact claims regulators have fined companies for.
- It's sold by the same person telling you it works.
Wanting to fix this isn't foolish. It's love with nowhere to go. Don't crush it; aim it. Two true things, held together: "I know how much you want to help her, and I love you for it. And the honest thing is, the stuff that actually helps isn't the stuff being sold. It's her hearing checked, a walk together, her blood pressure handled." Honor the feeling, share one honest fact, and point the hope at the green list and the doctor, not the checkout page.
Bring the full bottle list to a pharmacist and ask by name. The ones that actually bite. methylene blue + antidepressants (serotonin syndrome); ginkgo, high-dose fish oil, or vitamin E + blood thinners (bleeding); high-dose vitamin B6 (nerve damage over time); and any supplement started without telling the doctor who manages their prescriptions. And never let a supplement or diet replace a medicine that's working.
The Bredesen protocol (ReCODE): in full
This one gets asked about more than everything else on this page combined, usually after someone reads The End of Alzheimer's or a relative sends a link. It deserves the actual detail rather than a verdict, so here is what it is, what the research genuinely shows, what it costs, and what you can take from it for nothing.
What it is. The argument is that Alzheimer's is not one disease with one cause but the end point of many contributors, so instead of one drug you test for and treat everything you find. In practice: a broad lab panel, then a personalized plan aimed at whatever it flags. The 2022 study lists the targets as inflammation, chronic infection, gut dysbiosis, insulin resistance, protein glycation, vascular disease, nocturnal hypoxemia (low oxygen at night, usually sleep apnea), hormone problems, nutrient deficiency, and toxin exposure. The lifestyle spine is a mostly-plant, low-carb diet with an overnight fast (they call it KetoFLEX 12/3), exercise, sleep, stress work, brain training, plus supplements chosen from your results.
What the research actually shows, stated precisely, because both the enthusiasts and the dismissers tend to round it off:
- There is peer-reviewed published work, and the site used to imply there wasn't. The main clinical one is a 2022 paper in the Journal of Alzheimer's Disease: 25 people with mild cognitive impairment or early dementia, nine months, and on every measure used (MoCA, CNS Vital Signs, a symptom questionnaire, and MRI volumes) the group improved, with no serious adverse events reported.
- And it was a pilot with no comparison group, which the authors say themselves: its stated purpose was to find out whether the approach was promising enough to justify a larger randomized controlled trial. That distinction is the whole ballgame. Without a control group you cannot separate the treatment from three things that inflate scores on their own: people get better at cognitive tests by taking them repeatedly, unusually bad days drift back toward normal, and everyone in the study was also sleeping better, moving more and getting their blood pressure and blood sugar handled, which we already know helps.
- The randomized trial now exists, and has not passed peer review yet. It reports 73 participants across six US sites over nine months, and as of this writing it is a December 2025 preprint: posted publicly, not yet reviewed by independent scientists, and not indexed in PubMed. A preprint is a claim, not a conclusion. If it comes through peer review intact, that genuinely changes the picture, and this page will say so.
What it costs, using Apollo Health's own published figures rather than anyone's estimate. The lab panel is $945 if ordered through them. They note you can have a practitioner order the same tests as "patient pay" through LabCorp or Quest. Many participants find insurance covers part of it, and commercial plans tend to cover more than Medicare. Follow-up testing is recommended every six months. Supplements, by their own estimate, run $150 to $450 a month. On top of that sit a monthly subscription and your practitioner's fees, which they say vary by region. So the honest range is low thousands a year at minimum, and that is before anyone's time.
Strip out the proprietary layer and most of the protocol's own spine is the green list further up this page. That list: exercise, sleep, treating sleep apnea, blood pressure and blood sugar under control, a Mediterranean-style plate, hearing loss treated, staying socially connected. Those are free or cheap, backed by evidence that does not depend on this protocol being right, and you can start any of them this week without a membership. If money is tight, that is not a consolation prize. It is the best-supported part of the whole thing.
If you want to try it anyway, and plenty of thoughtful families do, start here. Read the book first (libraries have it), take the lab results to your regular doctor as well, and hold to two rules that apply to every plan on this site. Nobody but the prescribing doctor changes a prescribed medicine. And no protocol is worth money you need for care, rent, or your own health. Supplements are not automatically harmless either: several on the amber list interact with common medicines, so the pharmacist should see the full bottle list. The practitioner questions that apply here are the same ones that apply to any doctor, and they're on the doctor page.
Checked July 2026 against PubMed, the 2022 paper in the Journal of Alzheimer's Disease, and Apollo Health's own published pricing. What would change this section: the 2025 randomized trial completing peer review. That is the specific thing worth watching, and it is on our maintenance calendar.
If you want a ReCODE practitioner in Arizona
Checked at source on 29 August 2026, using Apollo Health's own practitioner locator. Two things a family should know before spending anything.
- The whole state has four ReCODE-trained physicians, and all four are in Scottsdale. There are none anywhere else within 150 miles of Phoenix; the next nearest is Las Vegas, about 258 miles away.
- Apollo will not tell you their names until you have paid. The public locator returns a count per town and nothing more. Their own page says subscribers find their care team inside the participant dashboard. So the honest sequence is: subscribe first, meet the doctor second.
- Apollo also requires it: in their words, ReCODE means working with "a ReCODE Trained Physician, M.D., D.O., or international equivalent". Coaches and nutritionists appear in the same locator and cannot run the protocol.
One of the four is findable without paying, because she says so on her own website. We name her as a fact, not a recommendation, and we have shown our working so you can weigh it yourself.
Integrative Medicine of Arizona, 480-621-8638 · integrativemedicineaz.com
Verified independently in the federal NPI registry: NPI 1811905177, status active, Arizona licence 31114, primary specialty emergency medicine.
Stated on her own site, which we have not independently confirmed. Board certified in emergency medicine, Institute for Functional Medicine Certified Practitioner, fellowship at the Andrew Weil Center for Integrative Medicine, and certified practitioner of the Bredesen ReCODE protocol.
What we could not check, and you should: her licence standing with the Arizona Medical Board (their public lookup blocks automated checks, so open it yourself and search her name), and whether she appears in CMS Open Payments. Her site publishes no address, no prices and nothing about insurance or Medicare, so ask what this costs over six months, all in, in writing before you commit.
The thing to weigh: her primary specialty is emergency medicine, and a cognitive-decline programme sits outside it. That is not a mark against her, and her functional-medicine credentials are real. It is simply the question worth asking any practitioner: is this the thing you were trained to treat?
The bottom line
Risk reduction is real. Cure is not. Anyone who blurs that line is either mistaken or selling something. The kindest, cheapest, most powerful "brain health" moves are boring (hearing aids, a daily walk, blood pressure handled, people around the table), and they're the ones nobody runs an ad for. If a product ever makes the memory-cure promise, you already know how to read it: the other scam is hope, and it's worth protecting your family's money and heart from both.
Two trustworthy, ad-free places: the FDA's list of unproven Alzheimer's products, and the Alzheimer's Association's plain-language take on alternative treatments. Or just call the 24/7 helpline (1-800-272-3900) and ask. They field this question all day and sell nothing.
