“Protecting brain health in later life may require more than just solving puzzles or eating leafy greens. As dementia cases rise globally, researchers are exploring whether lifestyle changes can alter the brain's trajectory.”

“Amyloid-beta is a toxic 42-amino acid peptide that aggregates and forms plaques in the brain with age. Amyloid-beta is associated with Alzheimer's disease, a progressive neurodegenerative disease that can occur in middle or old age and is the most common cause of dementia.”

“These dual stressors activate physiological responses to stress that ultimately drive inflammation, the underlying cause of many chronic diseases, including atherosclerosis, diabetes, rheumatoid arthritis, and dementia.”

“White matter hyperintensities are areas in the brain that appear as intense white spots on magnetic resonance imaging (MRI) scans. They are often indicators of cerebral small blood vessel disease and are considered a risk factor for dementia.”

“Pericytes detach from the blood vessels in aging, driving the pathophysiology of neurological dysfunction, vascular dementia, and stroke. A recent study in rodents shows that pericytes also play roles in long-term memory formation.”

“Pericytes detach from the blood vessels in aging, driving the pathophysiology of neurological dysfunction, vascular dementia, and mood disorders like anxiety. Learn more in this episode featuring Dr. Axel Montagne.”

“In animal models, spermidine supplementation has been shown to prevent memory loss. Findings from a recent report detail the first experiment exploring the effects of spermidine supplementation on memory in older adults without dementia.”

“Roughly 50 million people have Alzheimer's disease worldwide. Researchers have developed a blood test that measures phospho-tau217 (p-tau217), a type of tau protein, and may be useful in diagnosing Alzheimer's disease as early as 20 years before symptoms manifest.”

“Obesity, or having excess body fat, is a known risk factor for a wide range of diseases, including diabetes, cancer, and dementia. Findings from a new study indicate that having brown fat is linked with lower risk of some chronic diseases.”

“Evidence suggests that insufficient sleep increases a person's risk of developing Alzheimer's disease and dementia. The investigators analyzed data collected in the National Health and Nutrition Examination Survey, an ongoing study of the health and nutritional status of people living in the United States.”
