abstract = {In the present study, we investigated the association of
genetic predisposition with specific dimensions of dementia
pathophysiology for global and domain-specific cognitive
decline in older adults. The sample was drawn from the
Hellenic Longitudinal Investigation of Aging and Diet
(HELIAD) study, comprising 512 cognitively normal
individuals over 64 years of age, with a mean follow-up of
2.9 years. Cognitive function was evaluated through a
neuropsychological test battery, while genetic
predisposition was assessed based on two distinct Polygenic
Risk Scores (PRS) for amyloid-beta 42 (Aβ42) and white
matter hyperintensities (WMH). The association of each PRS
with the cognitive decline rate was examined using
generalized estimating equation models. In the whole sample,
higher PRSs Aβ42 (β = -0.042) and WMH (β =-0.029) were
associated with a higher rate of global cognitive decline
per year, an association which remained significant in age,
sex, and education subgroups. Moreover, higher PRSs Aβ42
and WMH were related to significant memory decline only in
females, older, and highly educated participants. Thus,
while the association of both PRSs with global cognitive
decline over time was independent of age, sex, or education,
the relationship of the specific PRSs with the memory
decline rate appeared to vary depending on these factors.},
