- A new Northwestern Medicine preclinical study links estrogen loss in older females to memory decline via changes in the extracellular matrix (ECM).
- Nearly two-thirds of Alzheimer's disease cases are in women, with post-menopausal estrogen decline hypothesized to reduce brain protection against neurodegeneration.
- The study found that estrogen loss, aging, and female sex uniquely impact the ECM in the hippocampus, a key area for memory, potentially increasing Alzheimer's risk.
- Current Alzheimer's treatments focus on amyloid removal but show limited benefits; the research suggests a new approach by targeting ECM restoration to protect memory.
- Hormone replacement therapy (HRT) results for Alzheimer's prevention are mixed, highlighting the need for more research on estrogen's role and safer HRT strategies.
