As our understanding of brain health continues to evolve, researchers have uncovered a compelling link between blood sugar levels and the risk of dementia.1 While diabetes has long been recognized as a risk for cognitive decline, recent research has highlighted the role of blood sugar levels, even within the normal range, as a significant predictor of dementia risk.2 Studies have shown that higher fasting and post eating blood glucose levels are associated with an elevated risk of developing dementia, even in non-diabetics. These findings underscore the importance of maintaining optimal blood sugar control, not only for individuals with diabetes but also for the broader population.
Implications for Prevention and Management
The recognition of blood sugar as a modifiable risk factor for dementia offers new opportunities for prevention and management. Lifestyle interventions aimed at improving blood sugar control, such as adopting a healthy diet, engaging in regular physical activity, and maintaining a healthy weight, can help mitigate the risk of cognitive decline.
For individuals with diabetes, optimizing glycemic control through medication adherence, dietary modifications, and regular monitoring of blood sugar levels is paramount. Early detection and treatment of prediabetes and diabetes can also help prevent or delay the onset of dementia.
