A new study has linked pain reliever -- ibuprofen -- to a reduced risk for Parkinson's disease.
Researchers with Harvard University followed over 135-thousand people without Parkinson's for six years.
During that time - regular users of ibuprofen were nearly half as likely to develop Parkinson's than those who never took ibuprofen.
Those who took the most ibuprofen were at the lowest risk.
Further research is needed.
