I have come across a number of blog posts recently suggesting that Alzheimer’s disease might be a kind of diabetes. This is an interesting conjecture because it might help explain the connection between life-style and dementia.
Here is a review article published in 2008 that examines the evidence. The authors state:
“We conclude that the term “type 3 diabetes” accurately reflects the fact that AD represents a form of diabetes that selectively involves the brain and has molecular and biochemical features that overlap with both type 1 diabetes mellitus and T2DM.”
Risk of dementia is definitely higher for people with diabetes. Thus, it would be prudent to take steps that reduce our risk of diabetes.
