Description

This prospective 5-year study will examine how long-term type 2 diabetes characteristics and inflammation affect the development of cognitive decline in a cohort of 1000 cognitively intact (at recruitment) diabetic individuals 65 years and older living in Tel-Aviv, Israel. This study is a collaboration of the Icahn School of Medicine at Mount Sinai (ISMMS), NY, the Department of Psychiatry at the Sheba Medical Center, Israel, and the Department of Community Health of the Maccabi Health Services (MHS), the second largest HMO in Israel. Diagnostic consensus teleconferences including both Israeli and ADRC physicians will have clinical, neuropsychological, and MRI data collected by this project in addition to complete Maccabi Healthcare Services (HMO) laboratory and medical data. DNA will be collected and a data sharing plan is in place. The specific aims are to investigate the impact of baseline 1) inflammation, 2) poor long-term glycemic control, 3) diabetes medication, specifically metformin, and 4) MRI abnormalities, on the rate of cognitive decline. Additionally, the contribution of inflammation or MRI abnormalities to the associations of glycemic control or diabetes medication use with cognitive outcomes will be examined. Beyond investigating the relationship of cognitive decline in diabetes, identifying the impact of inflammation—a modifiable risk factor—within this relationship, has implications for mechanisms underlying incipient dementia in the general population, and could provide the basis for future intervention studies with potential great public health impact. Demonstrating how brain abnormalities link diabetes characteristics to cognitive decline would support a causative or contributive role of these characteristics in cognitive compromise. This study of diabetic individuals will investigate the roles of inflammation, poor glycemic control, use of diabetes medications, and brain abnormalities at baseline on the rates of cognitive decline.
