Q:

Is there a type 3 diabetes? I'm told that they discovered it in 2005. I want to know if this true. And I would like to find out more about it.

A:

There is very early speculation that type 3 diabetes involves insulin deficiency and insulin resistance that is just confined to the brain and is associated with the development of Alzheimer’s disease. In type 2 diabetes, insulin resistance is found in many parts of the body, particularly in the muscle cells; in type 3, it is theorized that insulin resistance is found mainly in the brain tissue. Theories involving Alzheimer’s disease, insulin metabolism and type 3 diabetes are in their infancy, but are important because they may affect how Alzheimer’s is studied – and perhaps how it will be treated in the future. If you or someone you know is suffering from Alzheimer’s and are interested in type 3 diabetes it is best to discuss it with a neurologist who specializes in the treatment of Alzheimer’s disease.
