Who could benefit from this research

Could help

Adults aged 21 and older who are in or approaching the menopausal transition or in midlife, with concerns about memory or sleep.

Less likely to help

Individuals without sleep disturbances or menopausal transition-related changes may experience limited direct benefits.

What this research studies

This project looks at how hormonal changes during the menopausal transition and daily sleep patterns influence brain networks involved in memory. Researchers will track hormone levels, sleep rhythms, and memory performance to identify early indicators of cognitive vulnerability before dementia symptoms appear. The team will use brain imaging and sleep measures to understand how menstrual cycles and menopause-related hormonal shifts impact memory-related brain activity. Findings could point to windows for early interventions to protect memory as people age. The work ties to Alzheimer’s disease research by focusing on factors that may increase dementia risk during midlife.

Why it matters

Potential benefit: If successful, the study could help identify early markers of cognitive risk and guide strategies to maintain memory and reduce dementia risk through midlife.

How similar studies have gone: Prior research shows menstrual-cycle–related changes in sleep and memory, suggesting this approach is plausible but still being explored.
