Do High Blood Sugar Levels Hinder Memory?

A preliminary study published in the American Academy of Neurology Journal suggests chronically high blood sugar levels in humans, without Type 2 diabetes, have a negative effect on their ability to remember and repeat a list of words.

The German study of 141 people, average age 63, without signs of memory problems but with elevated glucose levels showed a correlation between long term high blood-sugar levels and the inability to recall

words from a list. Researcher Agnes Floel finds that even in  this small study, people with normal blood sugar ranges could possibly prevent age related memory decline by lowering their blood glucose levels.  

Glucose level is determine by genetics, diet and recent emotional activity. 

Floel suggests the need for large clinical trials to determine if lowering glucose levels will help prevent some dementia's.                                                                                                         USA Today
