Parkinson’s disease may not be only responsible for the condition’s distinctive movement problems but may also affect vision, a new study has revealed.
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 of York’s Department of Biology have established a link between a mutation which triggers Parkinson’s and problems with vision in an animal model.
Scientists at York studied the impact of the most common Parkinson’s-related mutation on nerve cells in the visual system of the fruit fly, Drosophila.
