Research published in the New England Journal of Medicine indicates that elevated blood glucose levels may heighten the risk of developing dementia, even among individuals without diabetes. The study monitored 2,067 participants without dementia at the outset, tracking their glucose levels over a median period of 6.8 years. Findings revealed that non-diabetic individuals with a blood sugar level of 115 mg/dL had an 18% higher risk of dementia compared to those with levels at 100 mg/dL. For participants with diabetes, a blood sugar level of 190 mg/dL was associated with a 40% increased risk compared to those at 160 mg/dL. Overall, 25% of the participants developed dementia during the study.
While the study does not establish a direct causal relationship between high glucose levels and dementia, it underscores the importance of blood sugar management. Adopting a healthier lifestyle, including improved dietary habits and regular physical activity, plays a crucial role in controlling blood sugar levels. Engaging in consistent exercise not only aids in blood sugar regulation but also supports overall brain health. If physical discomforts hinder your ability to stay active, seeking appropriate interventions can help restore function and reduce reliance on over-the-counter medications.
In summary, maintaining optimal blood glucose levels through lifestyle modifications may reduce the risk of dementia, highlighting the interconnectedness of metabolic health and cognitive function.
