Predicting Alzheimer’s Before Symptoms Appear

28.11.2025 by qfx

The methodology predicts the progression of Alzheimer’s disease by generating plausible future brain image sequences from past observations, effectively reconstructing missing data through interpolation and then extrapolating forward in time to forecast subsequent brain states.

A new deep learning approach uses the brain’s own structural changes over time to forecast the progression of Alzheimer’s disease, potentially enabling earlier diagnosis and intervention.
