In this engaging discussion, Louisa Nicola, a neurophysiologist and founder of NeuroAthletics, shares her insights on women's brain health. She highlights the importance of lifestyle choices in fighting cognitive decline and Alzheimer's disease, particularly the role of exercise. Louisa explains how strength training and high-intensity workouts contribute to brain health and debunks myths around creatine. Additionally, she emphasizes the significance of omega-3s and strong social connections in enhancing cognitive function and overall well-being.
Alzheimer's disease largely stems from lifestyle choices rather than genetics, highlighting the need for proactive brain health management.
Exercise significantly improves brain health by increasing BDNF levels and clearing amyloid beta, essential for maintaining cognitive function.
Strong social relationships play a vital role in cognitive health, with supportive connections being crucial for brain resilience as we age.

Introduction of Premium Membership Even Better
A premium membership program called Even Better is being launched, providing unique access to comprehensive health information specifically for women. This membership includes opportunities for direct interactions through 'Ask Me Anything' sessions, where members can seek advice on topics related to perimenopause, menopause, fitness, nutrition, and more. Moreover, it features exclusive solo podcast episodes hosted by Dr. Stephanie Estima, focusing on essential takeaways and actionable strategies. Additionally, members can enjoy ad-free listening, early access to episodes, and discounts on recommended products.
The Stark Reality of Alzheimer's Disease
Currently, there are over 55 million individuals affected by Alzheimer's disease worldwide, with predictions suggesting this number could triple by 2050. Dr. Stephanie emphasizes the overwhelming influence of lifestyle factors on Alzheimer's, attributing around 99% of cases to lifestyle choices rather than genetics. It is crucial to recognize that dementia is often misperceived as a natural part of aging; instead, it signifies disruptions in brain cell networks. Thus, understanding the mechanisms behind Alzheimer's, including amyloid beta plaques and tau tangles, becomes essential for prevention and management.
Understanding the Mechanisms of Alzheimer's Disease
Dr. Stephanie clarifies that Alzheimer's disease, marked by the presence of amyloid beta and tau proteins, is a degenerative condition affecting both brain cells and their intercommunication. This deterioration in cell communication leads to cognitive decline, which is often misattributed to aging. A significant point discussed is the limited role of genetics in Alzheimer's, which only accounts for approximately 1% of cases; the remaining 99% is influenced by lifestyle choices. Such insights highlight the need for a proactive approach to brain health and the reduction of lifestyle-related risks.
Exercise and Sleep's Impact on Cognitive Health
Exercise is emphasized as a cornerstone of cognitive health, facilitating the clearance of amyloid beta and enhancing brain-derived neurotrophic factor (BDNF) levels, which support brain function. Aerobic activities, particularly when performed at moderate intensity, appear most beneficial, with a recommendation of at least three hours per week. Additionally, quality sleep plays a crucial role in the brain's ability to clear waste products, including toxic proteins. Dr. Stephanie outlines how sleep hygiene, such as a consistent bedtime and a conducive sleep environment, significantly contributes to maintaining cognitive health in women, particularly during menopause.
The Power of Resistance Training
Resistance training is highlighted as a powerful strategy not only for physical fitness but also for cognitive health in women. Engaging in strength training positively influences brain function by releasing myokines, which improve brain connectivity and cognitive performance. There's a strong correlation between muscle mass and brain size; hence, maintaining muscle strength is vital for cognitive longevity. Dr. Stephanie suggests that prioritizing strength over hypertrophy can lead to enhanced outcomes in brain health and overall wellbeing.
The Importance of Social Connections
Social relationships are crucial for maintaining cognitive health and overall wellbeing, often being overlooked in discussions about longevity. Research from Harvard indicates that individuals with strong social connections tend to have healthier brains as they age. Dr. Stephanie encourages listeners to evaluate their social networks and foster relationships that are supportive and enriching. She underscores that surrounding oneself with positive, uplifting individuals can not only enhance mood but also contribute significantly to cognitive resilience.
Dr. Stephanie welcomes neurophysiologist and former world-class athlete Louisa Nicola. Together, they dive into the critical topic of brain health, with a focus on cognitive decline, dementia, and Alzheimer's disease—conditions that disproportionately affect women. Louisa, founder of NeuroAthletics, brings her expertise in helping athletes and investors optimize their brain function.
