Could Parkinson’s disease be diagnosed with a simple eye exam?
A study published in the journal Neurobiology of Disease by a team from Université Laval suggests that this possibility deserves serious consideration. Indeed, the retina of individuals with Parkinson’s appears to respond differently to light stimuli compared to that of healthy individuals, according to the group’s findings.
Today, Parkinson’s is still most often diagnosed when a person consults a physician for motor symptoms such as tremors. “By that time, the disease has already been present for several years, and the brain neurons involved are already undergoing irreversible degeneration. This is why it’s essential to identify biomarkers that can detect Parkinson’s at an early stage,” explains the study’s lead author, Martin Lévesque, a professor in Université Laval’s Faculty of Medicine and a researcher at the CERVO Research Centre.
