Association of GA/HbA1c ratio and cognitive impairment in subjects with type 2 diabetes mellitus

The fluctuation of blood glucose levels per se is closely associated with cognitive impairment in elderly subjects with type 2 diabetes even when hypoglycemia is not accompanied. Since it is very easy to calculate GA/HbA1c ratio, we should check this ratio so that we can reduce the fluctuation of blood glucose levels especially in elderly subjects with type 2 diabetes.
