What “Brain scans and imaging” covers

Brain scans and imaging — MRI, PET and other scans: what they show, how early, and how reliably.

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.

SUVs in the pons and the inferior cerebellum indicated consistent clearance across all 51 subjects. 5 key findings →

Cardiac index is associated with brain aging: the Framingham Heart Study

✓ Peer-reviewed alzhub usefulness score 52 out of 100. Circulation 2010-08-02

Although observational data cannot establish causality, our findings are consistent with the hypothesis that decreasing cardiac function, even at normal cardiac index levels, is associated with accelerated brain aging. 5 key findings →

Evidence: moderate

The derived threshold was used to categorize the 172 scans in the test cohort as negative or positive, and results were compared with categorization using visual assessment. 4 key findings →

Participants: 68 Evidence: moderate

Differentiating frontal and temporal variant frontotemporal dementia from Alzheimer's disease

✓ Peer-reviewed alzhub usefulness score 52 out of 100. Neurology 2000-06-01

The double dissociation in performance on semantic memory and attention/executive function clearly separated the temporal and frontal variants of FTD and aids the early differentiation of FTD from AD. 3 key findings →

Evidence: low

Predicting MCI outcome with clinically available MRI and CSF biomarkers

✓ Peer-reviewed alzhub usefulness score 52 out of 100. Neurology 2011-10-12

Incorporating quantitative assessment of learning ability along with vMRI or CSF biomarkers in the clinical workup of MCI can provide critical information on risk of imminent conversion to AD. 3 key findings →

Evidence: low

Stepwise decreases in WM integrity as measured by both DTI and FLAIR were independently associated with stepwise increases in WMH risk, emphasizing that these modalities may provide complementary information for understanding the time course of aging-associated WM degeneration. 3 key findings →

Design: longitudinal study Evidence: moderate

This human study is based on an established cohort of "SuperAgers," 80+-year-old individuals with episodic memory function at a level equal to, or better than, individuals 20-30 years younger. 4 key findings →

Participants: 21 Evidence: moderate

Brain structural alterations before mild cognitive impairment

✓ Peer-reviewed alzhub usefulness score 52 out of 100. Neurology 2007-04-01

Structural brain changes in anatomic areas involved in higher cognitive processes precede clinical signs and symptoms in longitudinally followed normal subjects destined to develop mild cognitive impairment. 1 key finding →

Progressive aphasia secondary to Alzheimer disease vs FTLD pathology

✓ Peer-reviewed alzhub usefulness score 52 out of 100. Neurology 2008-01-01

A temporoparietal pattern of atrophy on MRI in patients with progressive fluent aphasia and relatively preserved processing speed is suggestive of underlying Alzheimer disease pathology rather than frontotemporal lobar degeneration with ubiquitin-only immunoreactive changes. 3 key findings →

Participants: 216 Evidence: low

DTI histograms may be used as an adjunct outcome measure in future therapeutic trials. 1 key finding →

Design: longitudinal study Evidence: moderate

We explored resting-state metabolic connectivity in prodromal Alzheimer's disease (pAD) patients and in healthy controls (CTR), through a voxel-wise interregional correlation analysis of 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) by means of statistical parametric mapping. 1 key finding →

Participants: 36 Evidence: low

Florbetapir F18 has been approved by the Food and Drug Administration for in vivo assessment of amyloid pathology in patients undergoing evaluation for Alzheimer disease (AD). 3 key findings →

Participants: 229 Evidence: low

Since the introduction of amyloid imaging nearly 10 years ago, this technique has gained widespread use and acceptance. 5 key findings →

Design: longitudinal study Evidence: moderate

The presence of either severe WMH or MTA was associated with a modest but non-significant increase in frequency of mild cognitive deficits (severe WMH: odds ratio (OR) = 1.9 (95% confidence interval (CI), 1.0 to 3.7); MTA present: OR = 1.5 (95% CI, 0.8 to 2.8)). 2 key findings →

Participants: 639 Evidence: low

Plasma long-chain omega-3 fatty acids and atrophy of the medial temporal lobe

✓ Peer-reviewed alzhub usefulness score 52 out of 100. Neurology 2012-08-01

The long-chain ω-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are potential candidates for interventions to delay Alzheimer disease (AD), but evidence from clinical studies is mixed. 1 key finding →

Participants: 281 Evidence: low

In both cohorts, CSF MTBR-tau243 was associated with tau-PET temporal meta-ROI burden (BioFINDER-2: β = 1.1, p = < 0.0001 and Knight-ADRC: β = 0.7, p = < 0.0001), and this association did not differ by sex (BioFINDER-2 β = 0.04, p = 0.6 and Knight-ADRC: β = 0.009, p = 0.9). 3 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.
