Find studies

A note on reading research. One study is rarely the final word.

We try to note the size of a study, whether it was in humans or animals, and how early-stage the finding is. If a summary here doesn't make that clear, treat it with extra caution and check the original source.

Mivelsiran takes a completely different approach from antibody drugs: it's injected into the spinal fluid and uses RNA interference to tell brain cells to make less of the amyloid precursor protein in the first place, rather than clearing plaques after they form. 5 key findings →

Design: phase-1-trial Participants: 19 Evidence: preliminary

This was the pivotal, large-scale trial meant to prove whether simufilam, a controversial experimental Alzheimer's drug, actually works. 5 key findings →

Retraction Note: A specific amyloid-beta protein assembly in the brain impairs memory

⚠ Retracted — do not rely on it alzhub usefulness score 16 out of 100. Nature 2024-06-24

Eighteen years after it was published, Nature formally retracted the landmark 2006 paper that had proposed a specific amyloid protein (Aβ*56) as a cause of memory loss in mice, citing evidence of image manipulation, including splicing, duplication, and use of an image-editing 'eraser' tool. 5 key findings →

Evidence: high

In September 2024 the SEC announced that Cassava Sciences and three individuals tied to the company agreed to pay over $40 million combined to settle federal charges that they misled investors about a 2020 Phase 2 trial of simufilam. 5 key findings →

Glial activation and neuroinflammation play significant roles in apoptosis as well as in the development of cognitive and memory deficits. 3 key findings →

OASIS-3 is a compilation of MRI and PET imaging and related clinical data for 1098 participants who were collected across several ongoing studies in the Washington University Knight Alzheimer Disease Research Center over the course of 15 years. 4 key findings →

Elderly patients with AD hypovitaminosis D are at increased risk for hip fracture. 3 key findings →

Participants: 29 Evidence: low

A high incidence of fractures, particularly of the hip, represents an important problem in patients with Alzheimer disease (AD), who are prone to falls and have osteoporosis. 2 key findings →

Participants: 15 Evidence: low

Further research with DEMQOL is needed to confirm these findings in an independent sample, evaluate responsiveness, investigate the feasibility of use in specific subgroups and in economic evaluation, and develop population norms. 2 key findings →

Participants: 130 Evidence: low

Future studies are encouraged to adopt personalized internet-based supportive interventions to improve the health of family caregivers and their care recipients. 3 key findings →

Design: systematic review Evidence: high

The results presented are sufficiently encouraging to recommend that the DEMQOL instruments be used alongside a generic measure such as the European Quality of Life-5 Dimensions (EQ-5D) in future studies of interventions in dementia as there was evidence that they can be more sensitive for patients at the milder end of disease and some limited evidence that the person with dementia measure may be able to reflect deterioration. 2 key findings →

How the 0–100 score works — and why some entries are capped

This is alzhub's own score. It is not an official metric, not an impact factor, and no journal, publisher or ranking body endorses it. We built it so that a reader who is not a scientist can tell a landmark trial from a conference abstract without having to already know the difference. Every point comes from one of 20 components, all of them printed on the study itself, so you can disagree with our arithmetic rather than having to trust the total.

Journals are placed in ordered tiers, never given a numeric impact factor — we could not verify current impact factors from a source we control, and an invented one would be worse than none. Tier 1 is the top-tier general journals (NEJM, The Lancet, JAMA, Nature, Science, Nature Medicine); tier 2 is the leading specialty journals; tier 3 is every other peer-reviewed journal. A separate part scores how much the journal's own papers are cited, which tells the tier-3 journals apart.

Two rules we don't bend. First, we never fill in a missing value: if a record does not state a sample size or a design, that component scores zero, and if we simply have no data for a part, such as a citation count, that part is left out and the study is scored on the parts we could check. The study card says which. Second, anything that is not a peer-reviewed article is capped at 16/100 and carries a warning chip — so a conference abstract or a company press release can never outrank a peer-reviewed paper, no matter how good it looks.

We rank a rigorous null result — a good trial showing that something does not work — above an early positive finding. Someone deciding whether to buy a supplement is served by that, and the rigour is already counted by the design and journal components.

The score is computed from the published data alone and is reproducible: the same file always yields the same numbers.

See the whole rubric drawn out → — four charts covering all 27,380 studies: how the scores are spread and where the cap bites, which of the 20 components the library is strong and weak on, which subjects rest on stronger evidence, and what kinds of study each subject is actually built from.

What this library is — and isn't

This is a large sample of the Alzheimer's literature, not an exhaustive index of it. It holds 27,380 records, built mostly from automated pulls of Europe PMC (60.6% of the library) and OpenAlex (18.6%), plus smaller pulls from PubMed, Crossref and medRxiv. If a study, a drug, or a finding isn't here, that is not evidence it doesn't exist in the literature — it may simply not have been pulled in yet.

1,032 records (3.8% of the library) are not peer-reviewed — 962 of those are preprints posted before any journal review, and the rest are conference abstracts, regulatory notices and reports. Every study card on this page states its status plainly, and the score above is capped for anything that isn't a peer-reviewed article.
