Blood sugar levels linked to brain shrinkage

Blood sugar levels at the high end of what is considered normal may put the brain at risk, a study from the Australian National University has found. Dr Nicolas Cherbuin from the Centre on Ageing, Health, and Wellbeing in the ANU College of Medicine, Biology and Environment, studied the brains of 249 healthy individuals in their early 60s who had blood sugar levels in the normal range, as defined by the World Health Organisation.
