🚨 New study by @MugeAkinci: we found that increasing physical activity over 4 years in midlife & new adherence to the @WHO guidelines was linked to lower amyloid burden. Sustained sedentarism was linked to cortical thinning.🏃🏾‍♀️🧠

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 https://t.co/goklFzOZep

🚨New paper from the lab

A.L. Turpin, supervised by @julie_gonn, investigated the association between #lifestyle at different life periods and #brain integrity in older adults

Now available (open access) in @GreenJournal

[Julie Gonneaud @julie_gonn]

👏 A HUGE congrats to Anne-Laure Turpin for her 1st first-author paper now published in @GreenJournal

She looked at how #lifestyle engagement in early, mid vs late-life promote different #reserve mechanisms in older adults 🧠

Dear Network,

We have decided to leave X for Bluesky as it no longer aligns with our values and objectives.

Preprint: Using 400k memory tests & 15k brain MRIs, we find no evidence that education enhances cognitive reserve. Edu linearly related to better mem, but not less brain or cogn decline, or more tolerance to atrophy 🧵@LCBC_UiO @LifebrainEU @UiO_LifeSci

New Research Reveals Key Link Between Telomeres and Alzheimer’s Disease
In a groundbreaking study, we explore how critically short telomeres may be associated with brain and blood markers of ageing and Alzheimer's disease in older adults.
