Exposure To Pesticides Could Cause Parkinson's

Scientists have shed new light on a link between Parkinson's disease and two pesticides, which they hope will improve both prevention and treatment for the neurodegenerative disease.

At present fewer than five per cent of Parkinson's cases are attributed to genetics while 95 per cent have unknown causes.
Now a team from the University of Missouri School of Medicine thinks toxins such as pesticides could play a part.

The scientists studied the molecular dysfunction that happens when proteins are exposed to enivironmental toxins such as rotenone and paraquat.

'This study provides the evidence that oxidative stress, possibly due to sustained exposure to environmental toxins, may serve as a primary cause of Parkinson’s,' said assistant professor Zezong Gu.
