Insulin Resistance Linked to Brain Shrinkage (Atrophy)

…according to a new report in Diabetes Care.  As if that weren’t bad enough, brain functioning was also adversely affected! The next question is: Would prevention or reversal of insulin resistance preserve the brain?  Stay tuned, because nobody knows yet.

Only a few of the study participants had diabetes.  The study at hand supports others that suggest diabetes predisposes to dementia.

What Can I Do About It Now?

You could have your doctor order some expensive blood tests to see if you’re insulin resistant. (Insurance may not pay for them, either.) Or you can measure your waist size. If your waist circumference is over 39 inches (99 cm) and you’re overweight or obese, odds are good that you have some insulin resistance.

A couple ways to improve your insulin sensitivity (reduce insulin resistance) are:

  • lose your excess fat weight
  • start a regular exercise program
