A recent study reveals a concerning connection between menopause symptoms and the likelihood of developing dementia in women. Approximately 80 percent of women report experiencing some type of menopause-related issues, and research indicates that a higher symptom burden may correlate with an increased risk of cognitive decline.
The findings stem from research published in the journal PLOS One by a team from the University of Calgary. The researchers meticulously analyzed data gathered from 896 postmenopausal women who participated in the Canadian Platform for Research Online to Investigate Health, Quality of Life, Cognition, Behaviour, Function, and Caregiving in Aging, commonly known as CAN-PROTECT.
As part of the study, these women detailed their experiences with perimenopausal symptoms. Their cognitive abilities were assessed through standardized measurements, including the Everyday Cognition (ECog-II) Scale and the Mild Behavioral Impairment Checklist (MBI-C). Higher scores on these tests signified greater cognitive decline.
Results indicated that women experiencing more extensive menopause symptoms displayed elevated scores on the cognitive assessments, reflecting a more pronounced decline. Lead study author Zahinoor Ismail, M.D., who holds appointments in psychiatry, neurology, epidemiology, and pathology at the University of Calgary, stated, “One of the most interesting findings was the association between menopausal symptom burden and mild behavioral impairment symptoms, which are increasingly recognized as an early indicator of dementia risk.”
Dr. Ismail emphasized the importance of considering not only cognitive health but also emotional well-being and social interactions, which may change during and after menopause. Although hormone therapy did not show a substantial link to cognitive function, it was significantly associated with a reduction in mild behavioral impairment symptoms, warranting further exploration of its role in long-term cognitive health.
Interestingly, participants who reported using estrogen-based hormone therapy during perimenopause experienced significantly lower severity in mild behavioral impairment symptoms. Alexa Fiffick, a board-certified family medicine physician with a specialization in menopause, noted the correlation between a higher symptom burden and diminished cognitive function, suggesting that even unacknowledged hot flashes could contribute to cognitive deterioration. She explained, “It is believed that the vasomotor symptoms are correlated with the development of white matter hyperintensities in the brain, resembling signs of vascular dementia on imaging.”
Moreover, Dr. Fiffick mentioned the potential for hormonal and non-hormonal therapy options to prevent cognitive decline, although definitive data is still forthcoming.
The researchers acknowledged significant limitations in their study. Dr. Ismail underscored that the research is cross-sectional, capturing a single snapshot rather than tracking the progression of cognitive changes over time. Consequently, it can identify potential associations but cannot definitively establish causation between menopause symptoms and changes in cognitive health.
She stated, “To better understand the long-term impact of menopause on dementia risk, future research should follow participants over time, integrating biological data like hormone levels and brain-related biomarkers.” It is crucial to explore how various symptoms interact to influence cognitive health. The study also failed to measure the severity of reported symptoms, which could prove important in understanding risk factors.
Furthermore, the research focused on commonly reported menopause symptoms, thereby excluding potentially significant additional symptoms experienced by some participants. Dr. Ismail pointed out, “It’s documented that there may be over 30 symptoms women experience during the menopause transition.” Despite including an ‘other symptoms’ category, this approach may not encapsulate the full range of experiences.
Moving forward, the study did not differentiate among various types or formulations of hormone therapy. Dr. Ismail remarked, “Future studies will investigate whether specific types of hormone therapy produce differing effects on brain health.”
Tamsen Fadal, a New York menopause expert and author of the upcoming book, “How to Menopause: Take Charge of Your Health, Reclaim Your Life, and Feel Even Better than Before,” expressed that she was not surprised by these findings. She affirmed, “Research has indicated this connection for some time. Brain scans of women in menopause reveal structural and metabolic changes, reinforcing the idea that we can’t dismiss these symptoms as simply normal aging.”
Dr. Fadal further highlighted that many women have faced dismissal regarding symptoms such as brain fog, memory lapses, and mood swings. She stated, “This research underscores that menopause represents a neurological transformation alongside hormonal shifts.”
As more data emerges regarding the relationship between menopause symptoms and cognitive health, raising awareness about these issues becomes increasingly vital. Women should feel empowered to discuss their symptoms openly with healthcare providers. This dialogue is critical for developing comprehensive strategies to support women during this significant phase of life.
Overall, as the field of women’s health advances, it is essential to prioritize understanding the multifaceted effects of menopause. This ongoing research can ultimately lead to improved care and resources that acknowledge the neurological and cognitive dimensions of menopause, reversing the narrative that these changes are merely a facet of aging.
