Most families try something outside the doctor’s office. A friend swears by coconut oil. A video says a spice blend or a pinch of lithium can stop the disease. This page takes those ideas seriously enough to check them. For each one we say what is claimed, what has been tested, and who makes money from it.

What families on forums say

Caregivers are sharp observers. They notice when someone sleeps better or smiles more. What one family can’t tell is whether the change came from the remedy, a good week, or something else that changed at the same time. That is what controlled trials are for. Below are the tips we saw most often on caregiver forums, each matched to the best evidence we could find.

Where we looked: ALZConnected (the Alzheimer’s Association forum), AgingCare, the UK Alzheimer’s Society forum, and ApoE4.info. We could not read Reddit or Facebook groups for this page, so nothing here is drawn from them.

The prevention crowd: ApoE4.info

ApoE4.info is a patient-run community for people who carry the APOE4 gene, which raises Alzheimer’s risk. Most members have no symptoms and are trying to prevent the disease. The thread titles we could see were about ketogenic diets, measuring ketones, the Bredesen protocol, and whether saturated fat is safe for gene carriers. We could see titles but could not open the threads, so we can only describe the topics. It is a highly engaged, self-experimenting group, and much of what it tests has not been tried in formal studies.

Alternative and integrative programs

These are the names families meet most often in books, podcasts and ads. Many give sensible advice about sleep, exercise and blood sugar, and much of it matches the mainstream evidence on our lowering-your-risk page. Most also sell tests, programs or supplements. One question cuts through the marketing: has this exact program been tested against a control group, by someone who doesn’t profit from it?

A neutral place to check any supplement

The Cognitive Vitality ratings from the Alzheimer’s Drug Discovery Foundation (ADDF) are free and written by neuroscientists. Each supplement, food or drug gets a rating for evidence, likely benefit and safety, including known drug interactions. The foundation sells no supplements. It does invest in drug development, which is worth knowing. When a program recommends a supplement, looking it up there takes two minutes.

Dale Bredesen and the ReCODE protocol

What it recommends. A personalized plan built on lab tests. The program says more than 36 factors drive decline. It uses a mildly ketogenic, plant-rich diet called KetoFLEX 12/3, with a 12-hour overnight fast, plus exercise, sleep, many supplements, and hormone and toxin work-ups.

What it sells. Apollo Health, where Dr. Bredesen is chief science officer, lists PreCODE at $39.95 a month and ReCODE at $75 a month, a blood-testing panel, meal kits through a partner, coaching, and practitioner certification ($1,495 for coaches, $2,495 for practitioners). Lab tests, supplements and practitioner fees come on top.

What the evidence shows. The first reports were small case series with no comparison group. In 2020 a UCSF neurologist, Joanna Hellmuth, reviewed them in Lancet Neurology. She found no controls, no randomization, missing information on people who didn’t improve, and an unvalidated questionnaire (read her critique). Apollo has published a rebuttal. A 2022 pilot of 25 people also had no control group. Apollo describes a 2025 randomized trial that is posted only as a preprint, not yet peer reviewed, and claims it beat the drug Leqembi. That comparison sets two different trials in different people side by side, which is not a like-for-like test.

Many parts of the protocol, such as exercise, sleep, and blood-sugar and blood-pressure control, match mainstream advice. The full package has not been tested in an independent, adequately sized trial with a control group.

Dean Ornish and the lifestyle trial

What it recommends. An intensive whole-food, plant-based diet, daily exercise, stress management and group support. Dr. Ornish’s program for heart disease has been covered by Medicare as intensive cardiac rehab since 2010.

What the evidence shows. This is the only program on this page with a peer-reviewed randomized trial in people with memory problems. It was small (51 people), short (20 weeks), and nobody could be blinded to a diet change. Some measures favored the lifestyle group, and one standard memory test just missed. A critique titled “the need for rigor” was published in the same journal; we were not able to read it in full. One of the co-authors is Miia Kivipelto, who led the FINGER prevention trial. A larger trial would settle a lot.

Ornish intensive lifestyle program in early Alzheimer’s

Randomized trial; participants knew which group they were in
People
51 enrolled, 49 completed; mild cognitive impairment or early Alzheimer’s
Length
20 weeks

Result A whole-food plant-based diet, exercise, stress management and group support. On a clinician’s overall rating, 10 of 24 in the lifestyle group improved vs 0 of 25 controls. Two dementia rating scales also favored the lifestyle group. A standard memory test (ADAS-Cog) just missed significance. Small, short, and registered after it started.

Who paid: Private donors. The paper says sponsors had no role in the study.

Conflicts: Dr. Ornish holds equity in Ornish Lifestyle Medicine, which sells the program.

Dean and Ayesha Sherzai

Two neurologists who describe themselves as directors of the Alzheimer’s Prevention Program at Loma Linda University Medical Center. We could not confirm whether that is current. Their plan, called NEURO Resolution, is reported to cover whole-food plant-based eating, exercise, stress, sleep, and mental and social activity. They sell books, online courses and the program; we could not open their site to confirm details or prices. Each part lines up with mainstream risk-factor evidence. We found no trial of their program as a whole.

David Perlmutter

A board-certified neurologist and author of Grain Brain, Drop Acid and Brain Defenders. He recommends low-carb or ketogenic eating, avoiding gluten, lowering uric acid and caring for gut bacteria. He sells books and courses and links recommended products. Good evidence ties diabetes and insulin resistance to dementia risk. There is no trial evidence that going gluten-free prevents dementia in people without celiac disease, and the role of uric acid is debated.

Mark Hyman

A functional-medicine doctor who recommends “root-cause” work on gut, inflammation, toxins and sleep, plus fish oil, magnesium and vitamin D. He also mentions treating hearing loss. He sells supplement stacks, including a memory formula, and co-founded the Function Health lab-testing company. His advice on sleep and hearing is reasonable. The supplements he names mostly have weak evidence (see our nutrition page).

Not what the trials tested

What’s being said

“Alzheimer’s Is Reversible – Here’s Proof.” Lifestyle trials show you can “not just slow” the disease “but reverse” it. “This is published data.”

Mark Hyman on The Tucker Carlson Show. The quoted words are from his December 2024 interview; a clip reported as posted May 22, 2025 carries the title.

What the studies actually show

The two trials he pointed to, FINGER and US POINTER, enrolled older adults who did not have dementia. Both found small improvements on thinking tests. Neither tested people with Alzheimer’s, and neither showed reversal. POINTER’s results were not yet published when he called it published data; they came out in July 2025. The other “proof” he gave was Richard Isaacson’s clinic study (no randomized control group, mostly people without dementia), Dale Bredesen’s book, and his own patients. The closest thing to a reversal trial is Dean Ornish’s 2024 study of 51 people over 20 weeks, covered above.

Hyman made the claim while describing Alzheimer’s blood tests from Function Health, a company he co-founded; he disclosed that on air.

Life Extension

A supplement company whose Alzheimer’s “protocol” lists huperzine A, lion’s mane, lipoic acid, acetyl-L-carnitine, ginseng, vitamins C and E, DHA, phosphatidylserine, B vitamins, ginkgo, curcumin, vinpocetine, PQQ and grape seed. The page itself says that many of these therapies are debated. The company sells most of them. Huperzine A works the same way as donepezil (Aricept), rivastigmine and galantamine. Never take it with them: side effects such as nausea, a slow heartbeat and fainting add up.

Daniel Amen and Amen Clinics

A psychiatrist whose clinics use SPECT brain scans to sort patients into “types”. According to McGill University’s Office for Science and Society, an initial evaluation runs about $3,000 to $4,000. The company also sells about 95 supplement products, courses, an infrared light cap (about $2,000) and hyperbaric oxygen (read McGill’s review). McGill notes that the American Psychiatric Association and the National Institute of Mental Health do not endorse SPECT for diagnosing psychiatric conditions or choosing treatment, and that no rigorous controlled trial of the Amen approach exists. Mainstream memory clinics do sometimes use SPECT or PET scans to help tell one type of dementia from another. That is a much narrower use.

Joseph Mercola

An osteopathic physician whose website sells supplements and devices. The FDA sent him repeated warning letters between 2005 and 2021 over illegal disease claims for products, including coconut oil. In 2016 he settled with the Federal Trade Commission over tanning-bed claims, paying $2.6 million in refunds. If a remedy comes from this source, check it against the Cognitive Vitality ratings first.

Richard Isaacson

A neurologist known for “preventive neurology”: individual risk-reduction plans for people with a family history, based on genetics, lab tests and lifestyle. He is widely reported to have founded the Alzheimer’s Prevention Clinic at Weill Cornell and to have moved to the Institute for Neurodegenerative Diseases in Florida. We have not yet confirmed his current role, his studies or his commercial ties, so we don’t grade his work here. His general approach sits close to mainstream prevention advice.

What’s being said

A morning mix of turmeric, ginger, cinnamon, cayenne, black pepper and honey protects the brain.

Our paraphrase of a widely shared social-media recipe

What the studies actually show

No human trial has tested any spice blend for dementia. The research on single ingredients is thin:

  • Curcumin (from turmeric). One small trial of 40 adults without dementia used a specially absorbed form, Theracurmin, at 90 mg twice a day for 18 months, and found better memory and attention. Regular curcumin at 2 to 4 g a day did nothing in a 36-person Alzheimer’s trial, and barely any reached the blood.
  • Cinnamon. A 2023 review found 40 studies, and only 2 were in people. Those 2 disagreed.

The blend is fine as food. It is not a proven treatment. Concentrated curcumin supplements can interact with some medicines, so mention them to the doctor.

The lithium story

In August 2025, Bruce Yankner’s lab at Harvard Medical School published a paper in Nature that set off a wave of social-media videos. It found lithium levels were lower in the brains of people with memory loss. In mice, a tiny dose of lithium orotate nearly prevented plaques and restored memory. No person was given lithium in the study.

Lithium is a natural element. Prescription lithium carbonate is a long-used psychiatric medicine, given at much higher doses. Tiny amounts occur in tap water. Over-the-counter lithium orotate sits in between. The evidence for each level is different, so it helps to take them one rung at a time.

  1. Donated brain tissue

    Association only

    What was found
    Lithium was the only metal consistently low in brains with memory loss (Aron and colleagues, 2025).
    What it means
    Low lithium goes with the disease. That alone doesn’t show that adding lithium helps.
  2. Mice

    Strong lab science, not people

    What was found
    Cutting lithium from the diet sped up plaques, tau and memory loss. Adding low-dose lithium orotate reversed it.
  3. Tap water

    Mixed results

    What was found
    Denmark: the highest-lithium water went with 17% less dementia, but a middle band went with 22% more. Scotland: no benefit, and slightly higher risk in women.
  4. Low prescription doses

    Small trials, a modest signal

    What was found
    Brazil, 45 people with mild memory loss for 12 months: somewhat less decline. Pittsburgh’s LATTICE, 80 people for 2 years: missed its formal goals, though verbal memory declined about half as fast.
  5. Orotate supplements

    No human trial

    What was found
    Nothing yet in people. The dose that helped mice has not been translated into a safe human dose.

The “Harvard lithium study”: lithium deficiency and the onset of Alzheimer’s

Design
Donated human brain tissue plus mouse experiments
People
391 donated brains; no living person took lithium
Length
3–9 months (mice)

Result Lithium was the only metal found consistently low in the brains of people with mild memory loss and Alzheimer’s. In mice, cutting dietary lithium sped up plaques, tau and memory loss. A tiny dose of lithium orotate in drinking water nearly prevented plaques and reversed memory loss in the mice. The senior author says people should not take lithium on their own until human trials find a safe, effective dose.

Who paid: National Institute on Aging; Ludwig, Glenn and Aging Mind foundations

Conflicts: Not reported

Dr. Yankner has been direct about what the study does not show. He told the Harvard Gazette that people should not take lithium compounds on their own, and that human trials are needed first. In his words: “Before recommending lithium orotate, we need to determine the effective and safe dose range in people.”

Too early

What’s being said

“A Harvard study proved low-dose lithium reverses Alzheimer’s.”

Widely shared social-media videos, 2025

What the study actually shows

The reversal happened in mice. In people, the study measured lithium in donated brains after death. Nobody took lithium. The authors call for human trials before anyone takes it for memory.

Lithium in drinking water

If tiny amounts protect the brain, places with more lithium in the water might have less dementia. Two large studies tested that idea and pointed in opposite directions.
