Alzheimer’s disease polygenic risk score associates with hippocampal subfield atrophy and immune-related genetic mechanism
Specific AD-SNPs enriched in immune-brain axis pathways rather than Aβ related processes, were associated with reduced volumes of CA1 and subiculum prior to dementia onset, which supports that AD-PRS may capture genetic susceptibility to concomitant neurodegenerative diseases frequently misdiagnosed as AD.
