🚨 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.🏃🏾♀️🧠 #Alzheimer #BrainHealth

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

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
