Up to age 60, adult brain volume completely dominated by stable individual diffs. At 80 yrs, up to 50% reflects differences in change. Interpretation: 1) We change similarly up to 60. 2) Group comparisons often not reflecting changes. @Edvardosg @LCBC_UiO direct.mit.edu/imag/article...

Stable Individual Differences Dominate Adult Brain Volume Variation Until Later Life
Abstract. Individual differences in the volumes of brain structures are often linked to various conditions, including Alzheimer’s disease, schizophrenia, and overall brain health. However, it remains ...

Use of brain age models frequently lead to wrong conclusions - unfortunately it is not easy to fix. Fortunately, there are better alternatives. @edvardg.bsky.social @fmrib-steve.bsky.social @didacvp.bsky.social @maxwellelliott.bsky.social @k.b.walhovd www.medrxiv.org/content/10.6...

Reconsidering Brain Age: Why Age-Prediction Models Fail as Measures of Brain Aging
Brain age models - machine-learning predictions of chronological age from brain imaging - are widely interpreted as markers of accelerated brain aging. Here we show that this interpretation cannot be ...

Does memory fade slowly, or in drops and bursts? We analyzed 728k tests from 210k people. Key finding: “stability” isn’t a trait you either have or don’t have - it’s often a time-limited state at different points in aging. Preprint "Punctuated Memory Change": 👇 www.biorxiv.org/content/10.6...

Vulnerability to memory decline in aging revealed by a mega-analysis of structural brain change - Nature Communications
Across 13 longitudinal studies (3,737 adults), the authors show that brain atrophy parallels memory loss, with a stronger coupling in later life. APOE ε4 increases decline, yet genetic risk does not m...

Why do some people lose memory faster with age? A mega-analysis of 13 longitudinal datasets (3,700+ adults, 10,000+ MRIs) shows that memory decline tracks brain atrophy, especially in the hippocampus, and that these links strengthen with age, but not APOE status: www.nature.com/articles/s41...

Very impressed with @didacvp.bsky.social's work in @natcomms.nature.com, the most thorough mapping of longitudinal memory-atrophy relationships in normal aging, showing both global and memory-specific associations, which grow stronger with age. Early accsess here: www.nature.com/articles/s41...

Using 4570 longitudinal MRIs + 1684 Aβ PET scans from cognitively healthy older adults @jamesmroe.bsky.social find cortical thickness changed ≥7 years before PET-detectable Aβ. Those who later developed high Aβ already had thicker cortex & less thinning. @LCBC_uio www.biorxiv.org/content/10.1...

Cortical thickness changes precede high levels of amyloid by at least seven years
Alzheimer's disease (AD) is now defined based on its underlying brain pathology, with the presence of amyloid (Aβ) plaques at high enough levels sufficient to warrant a diagnosis in the absence of cog...

@natmed.nature.com made a nice Research Briefing about our paper. Highglights with less details, the main conclusion is the same: Education does not affect memory decline or brain aging @LCBC_UiO @LifebrainEU www.nature.com/articles/s41...

Education does not affect memory decline or brain aging - Nature Medicine
Competing explanations account for education’s link to better memory and brain structure in older age. By analyzing more than 400,000 memory scores and over 15,000 MRI scans, we found the association ...

New in @NatureMedicine Education is not linked to slower memory or brain decline in aging. We analyzed 400,000 memory tests and 15,000 MRIs from 33 countries. Associations likely shaped by childhood schooling and development. @LCBC_UiO @LifebrainEU rdcu.be/ex8iC

International study shows that higher levels of education do not reduce rates of cognitive and brain decline in later years, contrary to views that education protects against such decline: www.nature.com/articles/s41... @rhens.bsky.social

Preprint: before age 60, between-people diffs in brain vols almost exclusively reflect stable diffs, while systematic diffs in rate-of-change in aging cause up to 40% of the variation to be due to change at 80 years. @edvardg.bsky.social 🧵https://www.biorxiv.org/content/10.1101/2025.05.26.655710v1

Very interesting from @VidalDidac - MUCH higher reliability for structural neuroimaging measures with longer follow-up time rather than more follow-ups or higher n. 2.-year follow-up requires 4 times higher n than 6-year follow up. @LCBC_UiO direct.mit.edu/imag/article...

Preprint from @didacvp.bsky.social - a common brain factor underlying memory decline in older age. Stronger associations in older, but independent of genetic Alzheimer risk. Very interesting work using >10.000 MRI scan. @LCBC_UiO www.biorxiv.org/content/10.1...

Check our latest: we mega-analysed 13 longitudinal studies, encompassing 3,737 adults and over 10,000 MRI scans, to explore the associations between structural brain changes and episodic memory decline with age and genetic predisposition (APOE 4 allele). 👇 www.biorxiv.org/content/10.1...

Preprint: Why is edu associated with better memory in aging? We used >400k memory tests & 15k brain MRIs: (1) Edu linearly related to memory, larger ICV & (slightly) larger vol in memory regions, (3) not less decline (mem+brain), (4) not enhanced tolerance to atrophy.🧵 medrxiv.org/cgi/content/...
