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.
The significance of the cerebrospinal fluid (CSF) Apolipoprotein E (APOE) level and whether it might have differential effects on brain function due to the presence of APOE ε 4 allele(s) in HIV-infected patients are unknown. 2 key findings →
Alzheimer's disease (AD) is a devastating neurodegenerative disease characterised clinically by a progressive decline in executive functions, memory and cognition. 1 key finding →
Cerebral amyloid angiopathy- related inflammation (CAA-ri) is an aggressive disease subtype of CAA with characteristic clinical and radiological findings. 5 key findings →
Lower BMI is associated with cerebral AD pathology rather than with cognitive impairment in elderly subjects with MCI and mild dementia. 3 key findings →
Our objective was to predict HIV-associated neurocognitive disorder (HAND) in HIV-infected people using plasma neuronal extracellular vesicle (nEV) proteins, clinical data, and machine learning. 1 key finding →
Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the presence of extracellular amyloid plaques (senile plaques) and intracellular neurofibrillary tangles formed by hyperphosphorylated tau protein. 3 key findings →

Cerebrospinal fluid (CSF) NFL concentrations were measured by ELISA (normal < 250 ng/l) in archived samples from 210 HIV-infected patients not taking antiretroviral treatment: 55 with AIDS dementia complex (ADC), 44 with various CNS opportunistic infections/tumours (CNS OIs), 95 without neurological symptoms or signs, and 16 with primary HIV infection (PHI). 3 key findings →

The aggregation and deposition of amyloid-β (Aβ) peptides into plaques is an early event in Alzheimer's disease (AD), which is followed by different aspects of neurodegeneration that can be measured in the cerebrospinal fluid (CSF) or plasma using neurofilament light (NFL), neurogranin (Ng), total Tau (T-Tau), and phosphorylated tau (P-Tau) levels. 4 key findings →

An anti-tau monoclonal antibody tau-2 was demonstrated to react with the cells which characteristically appeared in the subcortical nuclei of certain neurodegenerative disorders. 1 key finding →
Synaptic loss is the best surrogate for cognitive decline in Alzheimer disease (AD) and is more closely associated with cognitive function than amyloid or tau pathologies. 4 key findings →
Lecanemab is a humanized monoclonal antibody that binds soluble brain amyloid-β protein, promoting its removal and slowing the underlying process of Alzheimer disease. 1 This mechanism aligns with the amyloid hypothesis, a debated model of Alzheimer disease pathogenesis.1 Only patients with mild cognitive impairment (MCI) or mild dementia due to Alzheimer disease are eligible for lecanemab treatment. 1 key finding →
After adjusting for age, sex, race/ethnicity, education, APOE ε4, and physical activity, a greater multimorbidity burden (per 3 additional conditions) was associated with worse overall cognition (standardized β = -0.074, 95%CI -0.104 to -0.043) and biomarkers indicative of greater AD pathology, neurodegeneration, and SVD (Figure 1). 5 key findings →

Tau protein misfolding and deposition in the brain is a common factor across many neurodegenerative diseases, grouped under the term tauopathies. 1 key finding →
After adjusting for age, sex, race/ethnicity, education, APOE ε4, and physical activity, a greater multimorbidity burden (per 3 additional conditions) was associated with worse overall cognition (standardized β =-0.074, 95%CI -0.104 to -0.043) and biomarkers indicative of greater AD pathology, neurodegeneration, and SVD (Figure 1). 5 key findings →

In plasma, most complement analytes were not significantly different between spFTD and HC; the exceptions were C4 and FB, significantly decreased in spFTD vs HC ( p = 0.0192 and p = 0.0181, respectively), suggesting complement consumption in classical and alternative pathways. 3 key findings →
BackgroundRecently published clinical studies suggest that blood-based biomarker tests (BBMTs) for Alzheimer's disease (AD) provide value, but in the U.S., neither public nor private payers currently cover these tests. 1 key finding →

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.

— four charts covering all 27,780 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 27,780 records, built mostly from automated pulls of Europe PMC
(61.1% of the library) and OpenAlex (18.3%),
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.
1,034 records (3.7% 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.
