Insulin Resistance and Accelerated Cognitive Aging

Premature and accelerated brain aging trajectories have been observed among people with metabolic dysfunction, but mechanisms of these altered trajectories are not understood. Insulin resistance (IR) is known to change with age and affect cognition in older and elderly adults as well as in patients with mood disorders. The main purpose of the study is to describe the developmental trajectory of cognitive and neural biomarkers across the spectrum of metabolic dysfunction in overweight/obese adults younger than 50 years of age. The innovative study design will allow the investigators to examine cognitive outcome development over a 25-year span without an investment into the longitudinal observation of changes in cognition and neural function.
