Experiencing Hot Flashes During Sleep May Be an Early Indicator of Alzheimer’s Disease
A recent study utilizing blood-based biomarkers for Alzheimer’s disease (AD) has uncovered a significant correlation between hot flashes, particularly those occurring during sleep, and an increased risk of AD in women. These findings will be presented at the 2023 Annual Meeting of The Menopause Society, shedding light on a potential early indicator of dementia in women.
A novel investigation has proposed that hot flashes, specifically when they manifest during sleep, could serve as a biomarker for identifying women at a heightened risk of developing dementia.
For women navigating the challenging phase of menopause, hot flashes are already a formidable challenge. However, recent research suggests that when these hot flashes occur during sleep, they may serve as early warning signs of an elevated susceptibility to Alzheimer’s disease (AD). What’s more, the study reveals that a greater frequency of hot flashes is associated with an increased risk of the disease. These groundbreaking results are set to be unveiled at the 2023 Annual Meeting of The Menopause Society, taking place in Philadelphia from September 27th to 30th.
Understanding Prevalence and Theories
Women account for two-thirds of all AD cases, and various theories have been proposed to explain this disparity. Many of these theories revolve around the decline in estrogen levels that women experience during the menopause transition. Previous research has already linked one of menopause’s most common symptoms, hot flashes, to impaired memory performance and alterations in brain structure, function, and connectivity. However, it remained uncertain whether hot flashes were linked to AD biomarkers.
The Role of Biomarkers in the New Study
Recent advancements in the assessment of AD have introduced blood-based biomarkers, which offer a valuable means of assessing risk decades before the onset of AD-related dementia. These biomarkers played a pivotal role in a recent study involving nearly 250 women in midlife. The study’s objective was to ascertain whether objectively measured hot flashes were associated with unfavorable AD biomarker profiles.
Key Research Findings
The study was led by Dr. Rebecca Thurston, Director of Women’s Biobehavioral Health at the University of Pittsburgh Department of Psychiatry, and Dr. Pauline Maki, Professor of Psychiatry at the University of Illinois at Chicago. The study’s results indicate that hot flashes experienced during sleep could serve as an indicator of women at risk of AD dementia. Furthermore, a higher frequency of hot flashes during sleep correlated with an increased likelihood of developing AD. These findings remained statistically significant even after adjustments for estradiol levels and sleep characteristics assessed via actigraphy. The measurement of hot flashes was conducted objectively through ambulatory skin conductance monitoring.
Implications of the Study
Dr. Rebecca Thurston remarks, “These findings imply that women who frequently experience hot flashes, particularly during sleep, may benefit from efforts aimed at reducing the risk of AD dementia.”
Dr. Stephanie Faubion, the medical director of The Menopause Society, adds, “Considering the adverse impact on quality of life and the financial burden associated with AD, it is crucial that we deepen our understanding of potential causes and early warning signs to take proactive measures before AD onset. This study underscores the importance of maintaining open dialogues between patients and healthcare professionals to carefully consider available treatment options.”
The study’s results will be presented at this year’s Annual Meeting of The Menopause Society as part of the presentation titled “Menopausal Vasomotor Symptoms and Plasma Alzheimer’s Disease Biomarkers.”

Frequently Asked Questions (FAQs) about Alzheimer’s Disease and Hot Flashes
What is the key finding of the study presented at The Menopause Society’s 2023 Annual Meeting?
The study’s primary finding is that hot flashes experienced during sleep may serve as an early indicator of an increased risk of Alzheimer’s disease (AD) in women. Moreover, a higher frequency of hot flashes during sleep is associated with a greater likelihood of developing AD.
Why is there a focus on women in this study?
Women are disproportionately affected by Alzheimer’s disease, constituting two-thirds of individuals with AD. This study specifically targets women to investigate the potential link between hot flashes, a common symptom of menopause, and the risk of AD.
How were hot flashes objectively measured in the study?
Hot flashes were objectively measured using ambulatory skin conductance monitoring, ensuring accurate and reliable data on their occurrence during sleep.
What are AD blood-based biomarkers, and why are they important in this study?
AD blood-based biomarkers are indicators in the blood that can help assess the risk of Alzheimer’s disease years before the onset of dementia symptoms. These biomarkers play a crucial role in the study by providing objective measures of AD risk and allowing for a deeper understanding of the association between hot flashes and AD.
What are the potential implications of these research findings?
The study suggests that women who frequently experience hot flashes, particularly during sleep, may benefit from efforts to reduce their risk of AD dementia. These findings underscore the importance of proactive healthcare measures and open dialogues between patients and healthcare professionals to consider available treatment options.
How can these findings impact women’s health and quality of life?
Understanding the potential connection between hot flashes and AD risk can lead to early interventions and risk reduction strategies. This knowledge may help improve the quality of life for women going through menopause and reduce the financial burden associated with Alzheimer’s disease.
What further research or steps are needed in light of these findings?
Future research could delve deeper into the mechanisms behind the association between hot flashes and AD risk. Additionally, efforts should focus on developing targeted interventions and treatments to mitigate this risk in women experiencing frequent hot flashes, especially during sleep.
