Does Type 2 Diabetes Cause Alzheimer’s Dementia?

“More basic research is critical.”

Several scientific studies, but not all, link type 2 diabetes with Alzheimer’s disease. Some go so far as to say Alzheimer’s is type 3 diabetes.

My Twitter feed brought to my attention a scientific article I thought would clarify the relationships between diabetes, carbohydrate consumption, and Alzheimer’s dementia (full text).

It didn’t.

Click the full text link to read all about insulin, amylin, insulin degrading enzyme, amyloid–β, and other factors that might explain the relationship between type 2 diabetes and Alzheimer’s dementia. You’ll also find a comprehensive annotated list of the scientific studies investigating the link between diabetes and Alzheimer’s.

Bottom line: We still don’t know the fundamental cause of Alzheimer’s disease. A cure and highly effective preventive measures are far in the future.

Action Plan For You

You may be able to reduce your risk of Alzheimer’s disease by:

  • avoiding type 2 diabetes
  • preventing progression of prediabetes to diabetes
  • avoiding obesity
  • exercising regularly
  • eating a Mediterranean-style diet

Carbohydrate restriction helps many folks prevent or resolve obesity, prediabetes, and type 2 diabetes.

    Don’t some refer to Alzheimer’s as “Type 3 diabetes”?

    I’m curious if you tell your patients that the best way to avoid tetanus is to never step on a rusty nail?
