“Maintaining early healthy blood pressure is critical to ensuring the proper functioning of blood vessels in the brain and blood-brain barrier integrity. Cumulative exposure to high blood pressure damages blood vessels and increases dementia risk.”

Dr. Rhonda Patrick discusses resistant starch, red light therapy risks, stem cells, and the link between benzodiazepines and dementia in her latest Q&A session.

“Vascular dysfunction is a common feature of most forms of dementia, including Alzheimer's disease. Identifying and treating vascular problems in the brain's smallest blood vessels could postpone the onset of symptoms and improve the quality of life for people with dementia.”

“Elevated levels of ketone bodies, such as beta-hydroxybutyrate, can have beneficial effects on several brain-related diseases. Research suggests that ketone bodies can increase blood flow in the brain by 30 to 40 percent, which may have profound effects for patients with brain injury or vascular dementia.”

“Other molecules – nicotinamide riboside and nicotinamide mononucleotide, known as NAD+ boosters – have similar beneficial effects on the brain, especially in the setting of vascular dementia.”

“Regardless of sex, genetic risk, or baseline cognition, the evidence is clear: Vitamin D is a powerful ally in reducing dementia risk. Though dosage details and optimal blood levels remain unknown, the link between vitamin D and brain health is too significant to ignore.”

“The Finnish studies are observational, so healthier behavior, socioeconomic factors, baseline disease, or other residual confounding could contribute to the association; they do not prove that sauna prevents dementia.”

“People who carry the APOE4 gene are at greater risk for vascular dysfunction and Alzheimer's disease. Identifying and treating vascular problems in the brain could postpone the onset of cognitive decline and improve the quality of life for people with dementia.”

“During the first 20 years of follow-up, sauna temperatures above 100°C were associated with about twice the dementia risk of temperatures below 80°C. Together, these data support consistent, tolerable heat exposure rather than pursuing the highest possible temperature.”

“Brain-health evidence includes complementary study designs. A UK Biobank analysis linked very low vitamin D status with dementia risk and used Mendelian randomization to estimate 54 percent higher risk at 25 versus 50 nanomoles per liter.”
