There are only two types of diabetes, as of 2015. However, studies show that Alzheimer's disease has biochemical and molecular features that are similar to those of type I and II diabetes, leading some scientists to refer to it as type III diabetes, reports the National Institutes of Health.
Type I diabetes occurs when the pancreas is producing little or no insulin, and type II occurs when the body is not responding normally to insulin, according to WebMD. People who suffer from type 1 diabetes need insulin injections. Another treatment is a pump that administers insulin on a continuous basis. It is possible to manage type II diabetes with diet and exercise. However, many people require medications that increase insulin production in the pancreas or improve how the body absorbs insulin.
Alzheimer's disease is a neurological disorder in which brain cells degenerate and die, leading to memory loss and impaired mental function, states Mayo Clinic. Symptoms include forgetfulness and confusion, followed by changes in behavior. Lack of exercise, poor diet and uncontrolled diabetes all increase the risk of being diagnosed with Alzheimer's disease. Factors that reduce the risk of Alzheimer's are engaging in mentally challenging activities, frequent social interaction and a stimulating job.
