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.

Ushering in the study and treatment of preclinical Alzheimer disease

✓ Peer-reviewed alzhub usefulness score 45 out of 100. Nature reviews. Neurology 2013-06-11

Researchers have begun to characterize the subtle biological and cognitive processes that precede the clinical onset of Alzheimer disease (AD), and to set the stage for accelerated evaluation of experimental treatments to delay the onset, reduce the risk of, or completely prevent clinical decline. 4 key findings →

Adherence to Mediterranean Diet and Implications for Cardiovascular Risk Prevention

✓ Peer-reviewed alzhub usefulness score 45 out of 100. Nutrients 2025-06-12

Significant correlations emerged between higher MEDAS scores and BMI (r = −0.53, p < 0.01), FM% (r = −0.49, p < 0.01), VAT (r = −0.63, p < 0.01), and cIMT (r = −0.88, p < 0.01). 5 key findings →

Evidence: low

DRRLS score of 83.61 ± 16.13, multiple linear regression showed that the patient's monthly individual income, the presence of chronic disease, health beliefs, and social support were independent influences on their dementia risk reduction lifestyle. 5 key findings →

Participants: 302 Evidence: low

Exceeding the ambitions of the Sendai Framework for Disaster Risk Reduction 2015-2030, to switch the focus of DRR (Disaster Risk Reduction) solutions from top-down to people-centred approaches, requires a better understanding of the complexity and dynamics of citizen and stakeholder engagement in DRR processes. 1 key finding →

Participants: 51 Evidence: low

Neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS), which are a consequence of the progressive loss of neuronal function and structure, cause significant cognitive impairment. 3 key findings →

Evidence: low

Can a Mediterranean diet prevent cognitive decline?

✓ Peer-reviewed alzhub usefulness score 45 out of 100. Zenodo (CERN European Organization for Nuclear Research) 2025-11-11

Current evidence suggests a potential for the Mediterranean diet to prevent cognitive decline, largely supported by observational studies, although randomized controlled trials show mixed results. 1 key finding →

Evidence: high

When systematically reviewed using the USDA Nutrition Evidence Systematic Review method and an a priori established protocol, a common theme emerged: diets characterized by higher consumption of vegetables, fruits, legumes, nuts, fish, seafood, and unsaturated vegetable oils, alongside lower intake of red and processed meats and sugar-sweetened beverages, are consistently associated with a reduced risk of cognitive decline and dementia. 2 key findings →

Design: systematic review Evidence: high

The Mediterranean diet and menopausal health: An EMAS position statement

✓ Peer-reviewed alzhub usefulness score 45 out of 100. Maturitas 2020-07-15

Globally, 985 million women are aged 50 and over, leading to increasing concerns about chronic conditions such as cardiovascular disease, osteoporosis, dementia, and cognitive decline, which can adversely affect quality of life and independent living. 5 key findings →

Evidence: high

Dietary patterns and cognition in older persons

✓ Peer-reviewed alzhub usefulness score 45 out of 100. Current opinion in clinical nutrition and metabolic care 2018-01-01

Numerous epidemiological studies have strongly suggested that multinutrient approaches using the Mediterranean diet (Med diet), dietary approach to systolic hypertension (DASH) and the Mediterranean-DASH diet intervention for neurodegenerative delay (MIND) are associated with a lower risk of cognitive impairment, MCI and Alzheimer's disease in older persons. 1 key finding →

Evidence: high

Harnessing digital health interventions to bridge the gap in prevention for older adults

✓ Peer-reviewed alzhub usefulness score 45 out of 100. Frontiers in Public Health 2024-01-08

The health issues associated with aging not only have a significant impact on the overall well-being of older individuals but also puts a lot of pressure of the healthcare system (3). 5 key findings →

Evidence: low

Microglia, the resident phagocytes of the retina, are believed to influence the development of retinopathy, but their exact contributions to vascular integrity and neuronal loss are unknown. 4 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.
