Wow, with the new UK Biobank rules, the dataset has just become way too expensive for the kind of computationally intensive work my lab does...

🚨 New paper out in eLife (with revisions to come!) Most have heard of brain age by now, but there remain some gaps for clinical use 🧠 Juan (Helen) Zhou 1️⃣ Brain age models mostly use data from Caucasian adults. Can these models work for non-Caucasian groups, especially children?

🚨 Predicting Alzheimer's Progression 🚨 A thread 🧵 1/ Accurate prediction of Alzheimer’s progression is critical for early intervention. How can we make predictions more precise and generalizable? 🧠✨ 📝 Read the preprint led by Chen Zhang : doi.org/10.1101/2024.1…

🚨 Brain Age vs Direct Models in Alzheimer’s disease (AD) 🚨 A thread 🧵 1/ Brain age is a powerful indicator of general brain health, trained on massive datasets. But does this translate to better prediction for specific outcomes, like AD? Preprint by Trevor Tan :

Thanks to everyone's feedback, we have updated our calculator to optimize sample size N & scan time T for fMRI studies. The first new feature is that users can explore how different N & T leads to different accuracy, e.g., N=1000 & T=30min => 81% accuracy.🧵
