Introduction

Recent studies illuminate a worrying correlation between menopausal symptoms and a heightened risk of dementia, particularly among women—a group already facing a higher vulnerability to cognitive decline. According to the World Health Organization (WHO), there are over 55 million people worldwide living with dementia, and women are disproportionately affected, being twice as likely to develop Alzheimer’s disease compared to men.

The Influence of Hormonal Changes

The particular risk women face may be influenced by longer life expectancies, but a significant factor seems to be the loss of the hormone estrogen that occurs after menopause. This hormonal change can lead to cognitive difficulties, raising questions about whether these challenges stem from the cessation of menstruation itself or the accompanying menopausal symptoms.

Research Findings

A research paper published in March 2025 in PLoS ONE by Jasper F. E. Crockford and colleagues closely examines this connection. Their findings reveal that each additional menopausal symptom correlates with a striking 5.37% increase in scores on the everyday cognition scale (ECog-II), which measures cognitive decline.

Study Details

Data for the study came from the CAN-PROTECT trial, an online observational cohort study involving dementia-free participants aged 18 and above residing in Canada. Subjects completed a demographic questionnaire along with extensive assessments on cognition. The menopausal symptom burden was evaluated using an 11-symptom scale, with scores indicating the severity of symptoms. The ECog-II assessment consisted of questions that gauged changes in memory, language skills, visual-spatial abilities, planning, organization, and executive function. Participants rated their cognitive changes from 0 to 3, with 0 denoting no change and 3 indicating significant deterioration.

Results Analysis

In the study, 896 menopausal participants identified as female at birth were analyzed, of which 666 reported menopausal symptoms. The results were very telling, as the study clearly indicated that every additional symptom was directly linked to a 5.37% rise in cognitive decline as measured by the ECog-II. Intriguingly, factors such as the age at which menopause began or the usage of hormone therapy did not seem to influence this relationship.

Implications of the Research

Crockford's research strongly posits that the number of menopausal symptoms experienced can serve as a critical risk factor for cognitive decline, thus increasing the likelihood of developing dementia. The insights gathered indicate that assessing menopausal symptom burden could be key to pinpointing at-risk individuals for dementia. Nevertheless, this study has its limitations, including a relatively small sample size, the potential for response bias due to self-completed online questionnaires, and a cross-sectional design that obscures clear cause-and-effect relationships.

Predicted Trends in Dementia Cases

Moreover, as we project into the future, GlobalData epidemiologists predict a surge in dementia cases among individuals aged 60 and older across major markets. For instance, diagnosed prevalent cases in women are expected to increase from 17.0 million in 2025 to an alarming 21.5 million by 2032, while for men, the cases will rise from 7.6 million to 9.5 million in the same timeframe.

Conclusion

In light of these findings, there is a pressing need for healthcare professionals to address menopausal symptoms seriously and consider them when assessing women’s risks for dementia. While research continues to evolve, early intervention and awareness could make a significant difference in managing cognitive health in menopausal women. Don't ignore the signs—understanding your menopausal symptoms could be more important than you think!
