Blood proteomics of menopause map to brain aging and dementia risk.

Blood proteomics reveal that menopause is linked to accelerated brain aging and increased dementia risk, with 11,925 women showing consistent associations.

• Why it matters: Understanding how menopause influences neurodegeneration is crucial because it may identify early biomarkers or targets for preventing dementia in women, a group at higher risk.
• What they did: The study analyzed blood proteomics data from 80 women across menopausal stages and validated findings in over 2,800 women, then extended the analysis to four larger cohorts totaling nearly 12,000 participants.
• The result: Menopause-related proteomic changes, especially inflammatory and catabolic processes, correlate with cognitive decline and dementia risk, suggesting potential biomarkers and therapeutic avenues for brain health.
