The work, which is published in the journal Occupational and Environmental Medicine, was carried out under the Fifth Framework Programme (FP5) Geoparkinson project, which aimed to investigate how genetic and environmental factors interact to cause Parkinson's disease and related conditions.
The researchers interviewed almost 1,000 patients with Parkinson's or related disorders from Italy, Malta, Scotland, Sweden and Romania. Participants were quizzed on their lifetime exposure to pesticides, solvents, iron, copper and manganese, as well as their experiences of being knocked unconscious and any family history of Parkinson's. The researchers also interviewed 2,000 people without Parkinson's, and compared their responses to those of the group with Parkinson's.
They found that people who had been exposed to low levels of pesticides were 1.09 times more likely to develop Parkinson's disease than those who had never been exposed, while people who had been exposed to high levels of pesticides were 1.39 times more likely to be affected.
'This has implications for occupational and, perhaps, recreational users of these agents,' the researchers comment. 'Further research is needed to establish which pesticides are associated with this effect.
The study also revealed an association between head injury and Parkinson's, with people who had been knocked out once being 1.28 times more likely to develop Parkinson's than people who had never been knocked out. Furthermore, people who had been knocked out frequently were found to be 2.56 times more likely to develop the condition.
'This finding, if confirmed, has implications for all contact sports and, in particular, combat sports such as boxing,' the researchers write.
Meanwhile the study did not throw up any evidence linking solvent exposure or metal exposure to Parkinson's disease.
The study did however confirm that the strongest risk factor was having a close family relative with the disease, although the scientists stress that whether this is due to a shared environment or genetic predisposition is unclear.
'This study has provided important evidence of the increased risk of Parkinson's disease in relation to exposure to pesticides,' the scientists conclude. 'The exposure-response relationship suggests that pesticide exposure may be a causative and potentially modifiable risk factor.'

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
