Is Alzheimer's A Type of Diabetes?

Is Alzheimer's Type 3 Diabetes?  by Mark Bittman.  The New York Times.  September 25, 2012.

Key Ideas/Summary.  Bittman cites scientific research for the connection between poor diet and Alzheimer's.  The idea that Alzheimer's is Type 3 diabetes has been around since 2005.  However the link between poor diet and Alzheimer's  is becoming more convincing.  When brain cells do not take adequate blood sugar because of insulin resistance they lose function and the person can lose memory and become disoriented and most severely lose their personal sense of self.  While Alzheimer's is not "caused" by diabetes the two conditions have the same root, the consumption of hyperprocessed foods that interfere with insulin's many vital functions.  The implications are alarming:  With the rise of diabetes in lockstep with Alzheimer's,  costs for obesity related diseases will rise over the next 40 years by one trillion dollars.
