Parkinson's Mutation Linked to Visual Problems

"The most common genetic cause of Parkinson's is not only responsible for the condition's distinctive movement problems but may also affect vision, according to new research by scientists at the University of York," reports Medical News Today. "Parkinson's, the second most common form of neurodegenerative disease, principally affects people aged over 60. Its most common symptom is tremor and slowness of movement (bradykinesia) but some people with Parkinson's also experience changes in vision.  Now for the first time, researchers in the University's Department of Biology have established a link between a mutation which triggers Parkinson's and problems with vision in an animal model."
