The Relationship Between Memory Loss and Blood Sugar Levels [Video]

Memory lapses can be assessed through blood sugar and HbA1c levels in health check-ups. High levels of these indicators suggest cognitive decline. Especially, working memory is influenced by blood sugar levels. When blood sugar rises, insulin is secreted in large quantities, leading to the absorption of glucose by cells and muscles. However, even with normal insulin secretion, the brain might not receive enough glucose. The brain requires 100g of glucose per day, and a lack of glucose impairs its function. The hippocampus, responsible for memory, is particularly affected. Prolonged high blood sugar increases the risk of Alzheimer’s disease. Therefore, it’s crucial to control blood sugar levels and prevent excessive carbohydrate intake.
