Clinical Study of GKT in Diabetes Related Dementia

Summary

Recently a new clinical dementia subgroup based on brain imaging, called "diabetes related dementia (DrD)". DrD, unlike Alzheimer's disease and vascular dementia, is considered a "controllable" or "modifiable" form of dementia. However, there is currently a lack of corresponding treatment measures. Ginkgo biloba ketone ester tablets are extracts of Ginkgo biloba leaves. Previous studies have shown that they can increase cerebral blood flow, reduce cerebrovascular resistance, improve cerebral circulation, and are beneficial for the treatment of cognitive impairment. This project intends to explore the role of ginkgo ketoester tablets in diabetes related dementia through a multicenter randomized double-blind controlled clinical study.
