" A new study finds that prior herpesvirus infections are linked to a faster age-related increase in blood biomarkers associated with dementia, even in cognitively healthy women. Researchers measured five key biomarkers in 167 women and found that seropositivity for HHVs doubled the rate of biomarker accumulation compared to those without prior infection. The strongest viral associations were seen for Epstein-Barr virus and HHV6, with amyloid-beta and phosphorylated tau levels most affected. These findings support the hypothesis that chronic viral infections may accelerate neurodegeneration and raise dementia risk independently of genetic factors."
