There is no single test available at the time to specifically diagnose Alzheimer's disease or to only show the risk for it. New research, however, indicates that a common test like fasting glucose may tell us something about the risk (Burns CM, et al. 2014). When regional cerebral metabolic rate for glucose in brain regions usually affected by Alzheimer disease was measured, a correlation with fasting glucose levels was found. Higher fasting glucose levels in cognitively normal, non diabetic adults were correlated with lower regional cerebral metabolic rate.
This means that higher fasting glucose levels may be associated with the pathophysiology of Alzheimer's disease and increase the risk for this disease.
What is the solution? A diet consisting of high nutrient, low glycemic index food, exercise and meditation for better handling of stress. This type of lifestyle will also reduce the risk for all other chronic conditions as well.
