Study: Physical activity tied to brain health in adults at risk for Alzheimer's

University of Wisconsin at Madison researchers who used FDG-PET imaging found that cognitively healthy late-middle-aged adults at high risk for Alzheimer's disease who had moderate daily physical activity had elevated glucose-metabolism levels in all brain regions, compared with those who had light daily exercise. The findings in the Journal of Alzheimer's Disease also showed improved glucose-metabolism profiles among those who had at least 68 minutes of moderate daily exercise, compared with those who spent less time on exercise.
