Introduction: The Overlooked Link Between Metabolic Health and Dementia
Dementia, an umbrella term describing the progressive decline in memory, thinking, and cognitive function, poses a growing public health burden worldwide. While genetics and age are well-known factors, emerging evidence spotlights the significant role of metabolic health in dementia risk, particularly in older adults. The phrase “five highs” (or “五高” in Chinese), commonly used to describe metabolic disturbances among middle-aged and elderly individuals, mirrors what medical science defines as metabolic syndrome—a constellation of metabolic abnormalities that do more than affect the heart and blood vessels; they silently endanger brain function.
Recent research involving over 4.3 million people provides important warnings about the dangers hidden within this syndrome. This article unpacks the components of metabolic syndrome, the evidence linking it to dementia, common misconceptions, and practical steps to reduce your risk.
