Exposure to pesticides leads to a 33 to 80 per cent increased risk of developing Parkinson’s disease, according to a meta-analysis of previous studies.
A team led by Dr Emanuele Cereda, of the IRCCS University Hospital San Matteo Foundation, in Italy, reviewed 104 studies that looked at links between Parkinson’s and weed, fungus, rodent or insect killers.
They found that exposure to pesticides in general led to an increased risk of developing Parkinson’s, while exposure to the pesticides paraquat or maneb/mancozeb was associated with a two-fold increase in risk.
“There was also a link between farming or country living and developing Parkinson's in some of the studies," said Cereda, quoted in Science Daily.
The study was published in Neurology, the medical journal of the American Academy of Neurology.
