“Controlled human studies support acute brain-related responses to high-intensity exercise. Six short all-out cycling intervals improved selected learning and executive measures while increasing circulating BDNF, IGF-1, and VEGF; lactate tracked several of these changes.”

“An emerging strategy in the prevention and (possibly) treatment of neurodegenerative diseases is starving cells as a means to induce general autophagy to help rid the cell of protein aggregates.”

“When produced during exercise (especially high intensity workouts like cycling, which shifts metabolism toward glycolysis to more quickly meet the high energetic demands), lactate switches on more than 600 genes involved in muscle adaptation, stimulates mitochondrial biogenesis – the process of making new mitochondria – and promotes protein synthesis, which is essential for muscle growth.”

“Dr. Rhonda Patrick talks at SF Nerd Nite about transgenerational effects of caloric restriction on longevity, B-vitamins silencing bad genes, cognitive stimulation reversing neurodegenerative disease, exercise increases neurogenesis, and ways in which vitamin D might influence aging.”

“Severe sleep deprivation offers one such model. In a randomized crossover study of 15 healthy young adults, a single dose of 0.35 grams per kilogram changed brain-energy measures and reduced deterioration on selected cognitive tasks during about 21 hours awake.”

“A small magnetic-resonance spectroscopy study also found that 20 grams per day for four weeks increased brain creatine by an average of about 8.7 percent, showing that brain uptake is possible but variable.”

“High energy demand is a promising research setting. In a randomized crossover study of 15 healthy adults undergoing 21 hours of sleep deprivation, a single 0.35-gram-per-kilogram dose changed cerebral energy measures and improved selected cognitive outcomes.”

“Time-restricted eating can help some people reduce eating opportunities, although a 12-month trial found no additional weight or body-fat benefit when an eight-hour eating window was added to calorie restriction. Sleep also affects appetite and fat distribution.”

“This is a proposed metabolic advantage, not proof of slower brain aging. Small TBI trials found that sodium lactate lowered intracranial pressure more than mannitol in severe TBI and improved cognitive scores more than 3% sodium chloride in mild TBI.”

“She uses that result to make consistency practical. Aerobic exercise does not need to be all-out every day, but sessions that raise heart rate and improve cardiorespiratory fitness provide a meaningful brain stimulus.”
