People with depression are at significantly greater risk for Parkinson’s disease than the general population, and those with severe depression are especially vulnerable, according to an article published online recently by Neurology, the journal of the American Academy of Neurology.

Researchers reviewed data on more than 560,000 people in Sweden and determined that those with depression developed Parkinson’s at a rate nearly three times that of the other study participants.
