“IGF-1 participates in a complex pathway known as the growth hormone/IGF-1 axis, where it exerts its role to accelerate aging. In this clip, Dr. Valter Longo explains how certain macronutrients influence the insulin/IGF-1/growth hormone axis to modulate aging in many cell types.”

“A growing body of evidence, however, suggests that a ketogenic diet, which is low in carbohydrates and rich in protein, fiber, and healthy fats, contributes to overall health and may be beneficial in preventing many chronic diseases, including Alzheimer's disease.”

“Evidence for cognition is less consistent. A meta-analysis of 16 randomized trials found a modest memory benefit but no significant improvement in overall cognition or executive function.”

“This should give us pause because APOE4 carriers have nearly four times more MMP9 and cyclophilin A than non-carriers. However, the good news is that studies in mice that carry APOE4 have shown that inhibiting the action of cyclophilin A partially restores vascular function and cognition.”

“Cognitive enhancement is a hot topic, but the best ways to sharpen focus, boost motivation, and support brain health aren't always clear-cut. Stimulants like nicotine and caffeine offer immediate benefits but come with trade-offs—some minor, others riskier.”

“In the prospective Framingham Offspring Study, people in the highest red-blood-cell DHA group had approximately 49 percent lower risk of developing Alzheimer's disease than those in the lowest group.”

“In this Aliquot, clinical psychologist Dr. Ashley Mason and sleep expert Dr. Matt Walker describe some of the behaviors that can make getting a good night's sleep difficult – and how cognitive behavioral therapy and meditation can provide help.”

“Since a driving force in the development of insomnia is change, especially change that affects relationships, employment, or family dynamics, Dr. Mason employs cognitive behavior techniques that help her patients identify what those changes are and develop strategies that promote, rather than hinder, sleep.”

“But the size of that effect in a real banana-blueberry smoothie remains unknown. No human trial has compared blueberries alone with blueberries plus banana while measuring blueberry metabolites, vascular function, cognition, or other health outcomes.”

“A pooled analysis of three COSMOS cognitive substudies involving 5,203 nonoverlapping participants found modest benefits for global cognition and episodic memory. Investigators estimated that the global-cognition difference corresponded to about two years of age-related change.”
