Menopause may raise women’s Alzheimer risk earlier than doctors once thought

A new review suggests the menopause transition may mark a critical window for Alzheimer's prevention in women, shifting focus toward earlier detection, sex-specific risk factors, and more personalized care.

In a recent review published in The Journal of Clinical Investigation, author Dr. Lisa Mosconi, a neuroscientist and women’s brain health specialist, examined how midlife hormonal changes and neuroendocrine aging influence Alzheimer's disease (AD) risk in women and identified opportunities for early, sex-specific prevention strategies.

Nearly two-thirds of individuals affected by AD are women, raising a critical question: why are women more vulnerable? Traditionally, this has been linked to longer life expectancy, but new evidence suggests deeper biological causes. Hormonal changes in midlife, especially menopause, can change brain biology and metabolism and may contribute to amyloid plaques and tau tangles, which are key biological markers of AD.

By the year 2050, it is estimated that over 1.2 billion women will experience menopause; therefore, it is important to understand these changes. At this time, there is not a lot of research that has focused on sex-specific mechanisms; thus, there is an urgent need for additional studies on these topics.
