Insulin Resistance May Impair Glucose Metabolism in Brain

Insulin resistance was associated with lower regional cerebral glucose metabolism in an imaging study of participants at risk for Alzheimer’s disease (AD).  All of the participants underwent a series of neuropsychological tests that mapped onto six cognitive factors. The most recent test scores before the imaging were used. Glucose and insulin levels were measured after a 12-hour fast, and all participants also underwent magnetic resonance imaging and FDG-PET. {read more here}
