Study looks at link between Parkinson's disease and depression

A study has revealed new information about the possible link between depression and Parkinson's disease.

If you remember this was something we talked about after actor Robin Williams committed suicide last November.

It was reported he battled depression and was in the early stages of Parkinson's disease when he died.

Researchers in Sweden tracked more than 500,000 people.

They found adults with depression developed Parkinson's at nearly three times the rate than people who did not suffer from depression.

Parkinson's is a nervous system disorder. It can affect someone's gait, their speech and it can cause tremors.

There is no cure but if prevention methods are found, this information gives us a better clue as to the types of people to target.
