Inability to regulate blood sugar has been associated with poor memory and could explain some aging-related memory loss, suggests a new study.

Conducted by NYU School of Medicine researchers, the study found that middle-aged non-diabetics and elderly people with impaired glucose tolerance had a smaller hippocampus, which is a brain structure involved in learning and memory.

“Our study suggests that this impairment may contribute to the memory deficits that occur as people age, and it raises the intriguing possibility that improving glucose tolerance could reverse some age-associated problems in cognition,” says Antonio Convit, the study’s lead author. More here.
