The body is basically a complex machine.
Granted it's mechanics on a very, very small level. But as understanding of nanotechnology increases eventually artificial pancreatic cells should become a reality (either that or we will be able to repair the cells). Then there's still the issue of how the body responds to insulin in the case of Type 2 diabetes. Nanosponges could potentially be made to mop up excess glucose.
This is complicated stuff and will take time to develop, but it's a matter of getting the hard work done. If the government would just fund nanotech research more we would see these innovations faster and our health and wealth would rise as a result.
Alzheimer's is being reclassified as Type 3 diabetes because of its association with insulin resistance in the brain. I believe that this reclassification is an indication of scientific progress as we understand more about the disease. Because we are already learning more, a cure can only be right around the corner.
While some scientists consider Alzheimer's disease to be a type of type III diabetes, at some point in the future medical advances Will finally find a cure for diabetes. It is just a matter of time. It takes a lot of work and research to crack evening the most menial of diseases or medical conditions. This is not easy, but it will happen.
I believe we will find a cure for all forms of diabetes in the distant future. We have a much better understanding of the human body than just a few years ago, and I believe we will use our knowledge to find a way to cure diabetes. This will all be in the very distant future, however.
With the advancement of technology that treats diabetes and with the increase of understanding on how diabetes occurs, needs to be treated and how it can be prevented will soon lead to a cure. Alzheimer's disease is often referred to as "the Type 3 Diabetes." With an increase in funding and awareness, doctors and researchers will be able to see if the two maladies have a direct correlation and if so, they will have the ability to develop and distribute a cure to prevent all types of diabetes.
