A new scientific study just linked some very random findings!
Apparently, people who have ever had a head injury and who were also exposed to the herbicide paraquat had almost a three times increased risk of developing Parkinson's disease.
UCLA's Fielding School of Public Health took a survey of over 1,000 adults.
Of those people, about 357 had Parkinson's disease.
Those with the disease were twice as likely to have reported a serious head injury that lead to unconsciousness for more than five minutes.
The lead author of the study said:
"While each of these two factors is associated with an increased risk of Parkinson's on their own, the combination is associated with greater risk than just adding the two factors together."
They believe that the traumatic brain injury can leave brain cells more vulnerable to the toxic herbicide.
So if you've ever lived near somewhere that may have been treated with paraquat, watch out for your head!
