27,380 Alzheimer's and dementia studies in plain English, each scored out of 100.
Though these findings cannot prove causality, and we cannot rule out the possibility of residual confounding, they provide more evidence of the risk of using these drugs in older patients, reinforcing the concept that they should not be used in the absence of clear need. 4 key findings →

The mechanism of action of benzodiazepines is through the modulation of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter that suppresses the central nervous system (CNS); the drugs have efficacy for short-term use (less than 1 month), but patients can develop a tolerance and dependence with long-term use.2 The benefits of benzodiazepines decrease over time and there are increased associated risks such as cognitive decline, accidental injuries, falls, and increased rates of hospital admissions and ED visits.2 Patients can also have paradoxical anxiety while on benzodiazepines.3 Studies have shown that long-term use of benzodiazepines increases the risk of dementia.4,5 Recent clinical practice guidelines recommend deprescribing benzodiazepines for older adults (age 65 years or older) for use in insomnia, and the American Geriatric Society (AGS) BEERs Criteria recommend avoidance of benzodiazepines in older adults because of the increased risk of adverse reactions such as falls and fractures.1,6 The AGS does say that benzodiazepines may be appropriate for use in older adults in certain circumstances such as ethanol withdrawal, and periprocedural anesthesia.6 The FDA has cautioned providers about prescribing benzodiazepines in patients using opioids but does not recommend withholding medications used for opioid use disorder in patients taking benzodiazepines.7,8 NPs can be instrumental in adequately treating anxiety and insomnia disorders with nonpharmacologic interventions (such as yoga and sleep hygiene) as well as with other medication classes that are not benzodiazepines. 5 key findings →

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.
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.
