People who have type 2 diabetes are more likely to develop Parkinson's disease as they age, though researchers are uncertain what accounts for the link between the two diseases, according to a new study being published in the April issue of Diabetes Care.

The study, by researchers in Finland, is the first large prospective study to find type 2 diabetes to be a risk factor for Parkinson's disease, a movement disorder characterized by muscle rigidity and tremors. According to the authors, people with type 2 diabetes are 83 percent more likely to be diagnosed with Parkinson's than people in the general population. The study found the association between the two diseases existed for both men and women, independently of other confounding factors.

"Diabetes might increase the risk of Parkinson's disease partly through excess body weight," the researchers hypothesized, since their work showed that excess body weight was also associated with an elevated risk of Parkinson's disease. However, they concluded that more research needed to be done to fully understand the mechanisms behind this link.

Diabetes Care, published by the American Diabetes Association, is the leading peer-reviewed journal of clinical research into the nation's fifth leading cause of death by disease. Diabetes also is a leading cause of heart disease and stroke, as well as the leading cause of adult blindness, kidney failure, and non-traumatic amputations.
