New framework enhances Alzheimer's diagnosis using longitudinal MRI scans

Researchers have developed Parcel2Progression (P2P), a novel longitudinal framework designed to improve Alzheimer's disease diagnosis using structural MRI scans. P2P addresses computational limitations by employing an Atlas-guided Parcel Encoder to represent 3D scans and a Longitudinal Transformer that integrates irregular, long-term patient data. This approach offers parcel-specific interpretability and scales efficiently with the number of scans, outperforming existing methods in predicting MCI to AD conversion and classifying AD versus cognitively normal individuals. The framework also demonstrates potential for anomaly detection and generalizability to other neurodegenerative diseases like frontotemporal dementia. AI

IMPACT This framework could improve early detection and personalized treatment strategies for Alzheimer's disease and other neurodegenerative conditions.
