Diabetes not a Parkinson’s disease risk

Despite several studies linking the two diseases, it appears that diabetes does not increase the risk of developing Parkinson’s disease. However, a diagnosis of Parkinson’s is thought to make diabetes diagnosis more likely.
A report published in Diabetes Care pointed to past research that had identified clear associations between diabetes and Parkinson’s disease. A number of potential links between the two conditions have been guessed at, including inflammation and oxidative stress .
A research team from Harvard Medical School examined a large amount of data from the Physician’s Health Study. Dr. Jane Driver was reported as commenting: “The highest Parkinson’s disease risk was seen in individuals with short-duration, older-onset diabetes without complications .”
