Epigenetic changes in aging brain support stroke recovery in aging women

Official title: Epigenetics of the Aging Astrocyte: Implications for stroke

Funded at Texas A&m University Health Science Ctr · NIH-11391195 · Data updated 2026-11-12

This project explores how aging-related brain cells, especially astrocytes, respond after a stroke in older women and how hormones and epigenetic changes influence recovery and dementia risk.

Who could benefit from this research

Could help

Ideal candidates are aging women or those represented in the animal models that mirror menopause-related changes in stroke outcomes.

Less likely to help

Direct benefits may be limited for younger individuals or men, as the study centers on aging female biology and stroke.

What this research studies

This study focuses on women 21+ who are aging and at risk for stroke and dementia. It uses animal models to mirror menopause effects and analyzes epigenetic changes in astrocytes after stroke. It also examines how estrogen or its absence affects stroke outcomes and long-term cognition and mood. The goal is to understand why stroke outcomes differ with age and menopause to guide future therapies.

Why it matters

Potential benefit: If successful, findings could lead to age- and sex-specific strategies to improve stroke outcomes and reduce dementia risk in aging women.

How similar studies have gone: Previous work showed age- and hormone-related differences in stroke outcomes and promising epigenetic findings in aging astrocytes, suggesting potential for new therapeutic angles.
