Decoding Cognitive Decline in Women: Insights from a New Study

Sleep Study Aims to Unlock Dementia Risk Factors in Women

Alzheimer’s disease, a devastating form of dementia, disproportionately affects women, with twice as many women as men currently living with the condition. The centers for Disease Control and Prevention (CDC) projects that minority populations will experience the most notable increase in cases in the coming years, underscoring the urgent need for effective prevention strategies.

The Sleep-Dementia connection: A Growing Concern

for years, sleep disturbances have been recognized as a symptom of dementia. However, emerging research suggests a more profound connection: sleep disorders may actually contribute to the development of dementia. This paradigm shift is fueling new investigations into the intricate relationship between sleep and cognitive health.

REFRESH-NOW: A Novel Approach to Sleep Research

To delve deeper into this critical area, scientists at the Scripps Research Digital Trials Centre launched the Research Framework for Sleep Health – Neurocognitive Outcomes in Women Study, or REFRESH-NOW. This innovative study focuses on women aged 55 and older, seeking to determine how sleep duration and irregularity impact neurocognition.

Leveraging Technology for Continuous Data Collection

The REFRESH-NOW study utilizes wrist-worn activity trackers and smartwatches to gather longitudinal sleep data over a three-year period.Stuti Jaiswal, MD, PhD, a physician-scientist specializing in sleep research, leads the project. Dr. Jaiswal emphasizes the potential of wearable technology to transform sleep research: “Wearables have the potential to revolutionize sleep research. While polysomnography is generally regarded as the gold standard for gathering sleep measurements, it only provides a snapshot of a person’s sleep characteristics based on data collected during a night spent in a sleep laboratory.”

The Advantages of Real-World Data

Traditional sleep studies frequently enough involve a controlled laboratory setting,which may not accurately reflect a person’s typical sleep patterns. Wearable devices offer a significant advantage by allowing researchers to collect data in a person’s natural environment. “That tool requires a person be hooked up to many different wires and sensors in a sleep laboratory, which is not a person’s natural sleep environment. On the other hand, commercially available activity trackers collect data passively making it very simple for people to participate in sleep research from the comfort of their own home and to share real-world data with researchers over months or even years,” explains Dr. Jaiswal. This approach provides a more comprehensive and realistic understanding of sleep patterns and their impact on cognitive function.

Practical Implications and Taking Action

Understanding the link between sleep and dementia risk could lead to the development of targeted interventions to improve sleep quality and possibly reduce the risk of cognitive decline. Individuals experiencing persistent sleep disturbances should consult with a healthcare professional to explore potential causes and treatment options. Simple lifestyle changes, such as establishing a regular sleep schedule, creating a relaxing bedtime routine, and optimizing the sleep environment, can also contribute to improved sleep health.

The REFRESH-NOW study represents a crucial step forward in our understanding of the complex relationship between sleep and dementia. By harnessing the power of wearable technology, researchers are gaining valuable insights that could pave the way for new prevention and treatment strategies.

Unlocking the Secrets of sleep and Dementia

In an unprecedented effort to understand the relationship between sleep disturbances and dementia, the Scripps Research Digital Trials Center has launched the REFRESH-NOW study. Led by sleep research expert Dr. Stuti Jaiswal, the initiative aims to explore how sleep duration and irregularity impact neurocognition in women aged 55 and older. We sat down with Dr. Jaiswal to discuss the implications of this groundbreaking research.

Dr. Jaiswal, thank you for joining us today. To kick things off, could you briefly explain the REFRESH-NOW study and its goals?

Dr. Stuti jaiswal: Thank you for having me. The REFRESH-NOW study is an innovative, longitudinal investigation focusing on women’s sleep health and its impact on cognitive function. Our primary goal is to determine how sleep duration and irregularity contribute to neurocognitive outcomes, bringing us one step closer to understanding the complex interplay between sleep and dementia.

The Power of Wearable Technology in Sleep Research

The REFRESH-NOW study employs wrist-worn activity trackers and smartwatches to gather continuous sleep data. What advantages does this approach offer over traditional sleep studies?

Dr. Jaiswal: Wearable technology is revolutionizing sleep research. Unlike polysomnography, which provides a snapshot of sleep in a lab setting, wearables allow us to collect data passively and continuously in participants’ natural environments. This real-world data offers a more comprehensive and accurate representation of an individual’s sleep patterns and their impact on cognitive function.

The Importance of Real-World Data in Sleep Research

How does collecting data in participants’ natural environments help advance our understanding of sleep’s role in cognitive health?

Dr.Jaiswal: Traditional sleep studies often involve highly controlled lab settings, which may not reflect participants’ typical sleep patterns. By gathering real-world data, we can better understand the true relationship between sleep and cognition. This understanding can inform the development of targeted interventions to improve sleep quality and potentially reduce dementia risk.

Making Sense of Sleep and Dementia

What are the potential practical implications of your findings on the general public, and how can individuals take action to improve their sleep health?

Dr. Jaiswal: Understanding the link between sleep and dementia risk could lead to development of targeted interventions.Individuals experiencing persistent sleep disturbances should consult with a healthcare professional.Simple lifestyle changes, such as establishing a regular sleep schedule, creating a relaxing bedtime routine, and optimizing the sleep surroundings, can also contribute to improved sleep health.

The Future of Sleep Research and Dementia Prevention

What excites you moast about the future of sleep research and its potential impact on dementia prevention?

Dr. Jaiswal: I’m most excited about the potential for personalized medicine. By understanding how individual sleep characteristics influence dementia risk, we can tailor interventions to each person’s unique needs. This could make a profound difference in combating the growing dementia epidemic.

Thank you, Dr.Jaiswal, for sharing your insights on the REFRESH-NOW study and the promising future of sleep research in dementia prevention.
