Association of metformin use with Alzheimer's disease in patients with newly diagnosed type 2 diabetes: a population-based nested case-control study.

ABSTRACT: Metformin reduces insulin resistance, which constitutes a pathophysiological connection of diabetes with Alzheimer's disease (AD), but the evidence of metformin on AD development was still insufficient and conflicting. We investigated AD risk in patients with newly diagnosed type 2 DM treated with metformin.
