High blood sugar associated with prediabetes may increase the risk for Alzheimer's disease, a new study suggests. Researchers found that insulin resistance – higher-than-normal levels of blood sugar that often precede type 2 diabetes – was related to poorer performance on memory tests taken by late-middle-age adults. Dr. Sam Gandy, director of the Center for Cognitive Health at The Mount Sinai Hospital, said it appears there may be a difference "between the dementia related to full-blown diabetes, which seems to be primarily dementia caused by hardening of the arteries in the brain, and the mental impact of insulin resistance, which some investigators believe is associated with Alzheimer's. We have long thought of Alzheimer's as a disease of defective brain signaling," said Dr. Gandy, who had no role in the study. "Conceivably, there is also a disease of defective insulin signaling, which this paper would support." Learn more
