How glucose exerts these effects and whether dietary or lifestyle Future research will need to characterize Or glucose intolerance, higher blood sugar may harm the brain andĭisrupt memory function. These findings indicate that even in the absence of diabetes That glucose might directly contribute to hippocampal atrophy,”īut she cautions that their data cannot establish a causal relation According to study co-author Agnesįlöel, a neurologist at Charité, the results “provide further evidence Structural changes partially accounted for the statistical link be tween glucose and memory.
