Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study aims to investigate the effects of DPP-4 Is+ metformin versus SGLT2 Is + metformin on the risk of cognitive decline and depression in patients with T2DM.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Older people suffering from Type 2 Diabetes Mellitus possess a major risk for age related cognitive dysfunction and dementia, mainly due to vascular complications.

SGLT2 inhibitors and DPP4 inhibitors are antidiabetic medications, have shown promise not only in glycemic control but also in potentially mitigating cognitive decline and depressive symptoms.
