APOE ɛ4 genotype is linked to higher dementia risk in Lewy body disease, and quantitative digital pathology predicts dementia better than conventional staging.
- Why it matters: Dementia in Lewy body diseases has heterogeneous causes, but the relative roles of genetics, co-pathology, and vascular factors are unclear.
- What they did: In 399 post-mortem brains, machine-learning image analysis quantified α-synuclein, amyloid-β, and phosphorylated tau across regions, integrating APOE genotype, clinical data, and ischaemic pathology.
- The result: Quantitative pathology strongly correlated with semi-quantitative ratings and outperformed conventional staging; APOE ɛ3 and ɛ4 carriers showed distinct risk profiles, and orthostatic hypotension plus ischaemic pathology increased risk only in ɛ3 carriers with low Lewy and Alzheimer proteinopathy burden.
