In this episode of the Sober Head Podcast, Dr. Esra Çavuşoğlu, PhD welcomes Louisa Nicola, MMed, PhD(c), Neurophysiologist, Neurosurgery.
Dr. Esra Çavuşoğlu, PhD speaks with neurophysiologist and brain performance expert Louisa Nicola about one of the most urgent health challenges of our time: Alzheimer’s disease and women’s brain health. Did you know that nearly 70% of Alzheimer’s patients are women? In this powerful conversation, Louisa Nicola explains why women face a higher risk of Alzheimer’s and how factors such as menopause, estrogen decline, sleep disruption, metabolic health, and lifestyle habits may play a major role in brain aging.
Louisa also shares groundbreaking insights about the connection between muscle and brain health. During exercise, muscles release molecules called myokines, which can cross the blood-brain barrier and support brain repair, neuroplasticity, and cognitive function.
They also discuss how BDNF, strength training, aerobic exercise, and VO₂ max training can help maintain brain resilience and reduce the risk of neurodegenerative diseases.

This episode also explores:
• The difference between Alzheimer’s disease and dementia
• Why Alzheimer’s may begin 20-30 years before diagnosis
• The role of sleep and the glymphatic system in clearing brain toxins
• The impact of ApoE4 genetics and cholesterol metabolism
• Why muscle is considered a cognitive organ
• How strength training and compound movements support brain health
• The science behind VO₂ max training and longevity
• Why doing hard things, physically and mentally, protects the brain

Louisa also shares her practical recommendations for exercise, sleep routines, metabolic health, and daily habits that may help protect the brain and support long-term cognitive performance.
If you are interested in longevity, brain optimization, women’s health, and Alzheimer’s prevention, this episode is packed with science-backed insights you don’t want to miss.
