Higher Amyloid PET Signal and Lower APOE ε4 Frequency Distinguish Iatrogenic From Sporadic Cerebral Amyloid Angiopathy

By MedXY 05/07/2026

A single-center cross-sectional study found that iatrogenic cerebral amyloid angiopathy carries a higher amyloid PET burden, weaker CSF-PET coupling, and less APOE ε4 enrichment than sporadic disease, supporting a biologically distinct mechanism.

Decoding Dementia in Lewy Body Disease: The Interplay of Quantitative Pathology, APOE Genotype, and Disease Heterogeneity

By MedXY 04/02/2026

Recent advances in digital pathology and machine learning reveal that APOE ε4 promotes proteinopathy and modifies dementia thresholds, while multi-modal trajectories suggest distinct pathways for disease progression in Lewy body disease.
