It's as simple as that.Glucose is the only fuel normally used by brain cells. Because neurons cannot store glucose, they depend on the bloodstream to deliver a constant supply of this precious fuel.
I am still wondering, using anorexia as an analogue if in both situations the brain is not receiving an adequate amount of glucose and nutrients, exactly how does the cerebral atrophy occur in anorexia? I have found research showing that the atrophy in anorexia can be reversible when proper eating is restored; what if some of the atrophy in MS is reversible?
