People with depression may be more likely to develop Parkinson's disease, according to a large study published in the May 20, 2015, online issue ofNeurology, the medical journal of the American Academy of Neurology.
"We saw this link between depression and Parkinson's disease during over a timespan of more than two decades, so depression may be a very early symptom of Parkinson's disease or a risk factor for the disease," said study author Peter Nordström, PhD, at Umeå University in Umeå, Sweden.
The researchers also examined siblings, and found no link between one sibling having depression and the other having Parkinson's disease. "This finding gives us more evidence that these two diseases are linked," said Nordström. "If the diseases were independent of each other but caused by the same genetic or early environmental factors, then we would expect to see the two diseases group together in siblings, but that didn't happen."
