Washington: A new study has revealed that people with insulin resistance and type 2 diabetes are more likely to develop plaques in the brain that are associated with Alzheimer’s disease. Insulin resistance, or the stage before diabetes, happens when insulin, a hormone in the body, becomes less effective in lowering blood sugar.
The study found that people who had abnormal results on three tests of blood sugar control had an increased risk of developing plaques. Plaques were found in 72 percent of people with insulin resistance and 62 percent of people with no indication of insulin resistance. However, the study did not find a link between diabetes factors and tangles in the brain. "Further studies are needed to determine if insulin resistance is a cause of the development of these plaques," said Sasaki. "It’s possible that by controlling or preventing diabetes, we might also be helping to prevent Alzheimer’s disease." The study has been published in the August 25, 2010, issue of Neurology, the medical journal of the American Academy of Neurology. ANI
