More evidence ties diabetes to Parkinson's risk

People with diabetes may have a heightened risk of developing Parkinson's disease, especially at a relatively young age, a new study finds.

Published in the journal Diabetes Care, the study adds to recent research linking diabetes to Parkinson's disease.

But neither this report nor the earlier ones prove that diabetes, itself, raises a person's risk of Parkinson's -- a disorder in which movement-regulating brain cells gradually become disabled or die.

Instead, researchers suspect that it's more likely diabetes and Parkinson's share some common underlying causes.
