Early Menopause: A Hidden Danger?

A groundbreaking study published in the journal *Alzheimer’s and Dementia* reveals that women who hit menopause before turning 40 face heightened risks of cognitive decline and severe depressive symptoms compared to their counterparts who experience menopause at 50 or later.

Why This Matters: Dementia's Gender Factor

Dementia disproportionately impacts women globally, leading researchers to suggest it may primarily be a female-focused health concern. The study analyzed 4,286 men alongside women, aiming to isolate the effects of early menopause on cognitive health.

Expert Insights: Depression's Role

Miharu Nakanishi, the study’s lead author and an associate professor at Tohoku University in Japan, emphasized the importance of addressing modifiable risk factors. "Early menopause significantly increases the risk of depression, which in turn boosts dementia risk," she stated. Understanding this intricate relationship could pave the way for new treatments that delay dementia onset in vulnerable women.

What Exactly Is Early Menopause?

Menopause marks the end of a woman’s menstrual cycles, typically occurring at an average age of 52 in the U.S. However, early menopause—or premature ovarian failure—affects about 5–10% of women. Factors that can trigger early menopause include smoking, excessive alcohol consumption, and a sedentary lifestyle.

The Study’s Structure: Unpacking Cognitive Performance

The researchers utilized data from the English Longitudinal Study of Ageing (ELSA) and divided menopause age into three categories: women under 40, those aged 40 to 49, and women 50 and older. Among 4,726 women studied, roughly 10% experienced early menopause.

Measuring Cognitive Skills: An In-Depth Look

Cognitive functions were assessed through interviews and self-completed questionnaires over a decade, starting in 2002. The study revealed that women's verbal fluency scores exhibited a significant decline over time, particularly among those who went through menopause early.

The Dreaded Association: Depression

Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale (CES-D). Women with early menopause showed notably higher levels of depressive symptoms, which were linked to their cognitive decline.

A Call to Action: Screening for Depression

Given these findings, Nakanishi and her team advocate for depression screenings in women facing early menopause, emphasizing the necessity of addressing mental health as a critical factor in dementia prevention.

This study not only underscores the urgent need for awareness of early menopause's impacts but also encourages proactive health measures to protect women's cognitive health.
