Glucose Levels and Risk of Dementia

This cohort study explored the link between glucose levels and dementia risk in older adults, including those with and without diabetes. Over a 6.8-year follow-up, higher glucose levels were associated with an increased risk of dementia in both groups. For non-diabetics, glucose levels of 115 mg/dL raised dementia risk by 18% compared to 100 mg/dL. Diabetics with levels of 190 mg/dL had a 40% higher risk than those at 160 mg/dL. The findings emphasize that glucose management may be crucial for reducing dementia risk, even in non-diabetic individuals, due to potential impacts on brain vascular health and metabolic function.

To lower dementia risk, maintain healthy glucose levels through a balanced diet low in processed sugars, regular exercise, and consistent medical monitoring. These measures benefit both diabetics and non-diabetics, given the significant associations found.
