Summary A multitask deep learning framework predicts both Alzheimer’s diagnosis and cognitive decline up to 36 months from a single baseline MRI scan, achieving 92.8% diagnostic accuracy without requiring biomarker testing or longitudinal imaging. Transcript INTRO So imagine you're a clinician and a patient comes in with early cognitive complaints. You order an MRI—pretty standard stuff, right? But what if that single scan could tell you not just whether they have Alzheimer's disease, but how much cognitive decline they're likely to experience over the next three years? That's essentially what a team just published in Nature Aging, and it's a pretty compelling example of how machine learning is quietly reshaping […]
