The stronger vascular dementia association suggests inflammatory/vascular mechanisms rather than amyloid/tau pathways as the primary mediator. This evidence base is stronger than prior estimates: the WHO's "50% elevated risk" figure comes from specific social frailty studies, while this larger, more rigorous analysis gives 19-31% depending on adjustment strategy.
