Sweet Dreams (but lost memories) (repost 2009)

A more appropriate title might be sweet forgetfulness. Higher blood sugar has been found to impair memory. Researchers conducting studies on older individuals using functional MRI found less blood flow in critical brain areas in those with even moderately elevated blood sugar. Since glucose tolerance, the ability for the body to appropriately handle glucose and normalize blood sugar declines with age, this has significant implications for aging individuals.

The major protective activity from elevated blood sugar caused by impaired glucose tolerance is exercise. Here we have another clear reason why exercise is good for us all. More details at the New York Times:
