Implication
Cohort study examines epigenetic aging's impact on incident dementia, suggesting biological markers may indicate risk.
Key Points
- Accelerated biological aging indicates a higher risk of incident mild cognitive impairment and dementia.
- The significant hazard ratios for dementia risk were 1.07 for DunedinPACE and 1.11 for AgeAccelGrim2.
- Analysis involved 6,069 cognitively unimpaired women, utilizing multivariable Cox proportional hazards models.
- Findings highlight the relevance of epigenetic biomarkers in predicting dementia development beyond chronological age.
