According to recent report, increased blood sugar levels could be to blame for the memory lapses that occur when individuals reach old age, regardless of their risk of diabetes.
Keeping blood glucose under control through exercise, diet and medication could reportedly be the best way to keep your marbles.
A team of US researchers found that increasing blood sugar levels, which occur naturally as the body gets older, strongly affect an area of the brain called the hippocampus. Older people rely strongly on this area of the brain to retain their memories.
Columbia University Medical Centre researcher Dr. Small was reported as commenting: “for the first time that blood glucose selectively targets the dentate gyrus is not only our most conclusive finding, but it is the most important for “normal” ageing – that is, hippocampal dysfunction that occurs in the absence of any disease states. There have been many proposed reasons for age-related hippocampal decline. This new study suggests that we may now know one of them. Beyond the obvious conclusion that preventing late-life disease would benefit the ageing hippocampus, our findings suggest that maintaining blood sugar levels, even in the absence of diabetes, could help maintain aspects of cognitive health.”
