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.

Felipe Da Gama, scientific coordinator of Chercheur d’un jour, recently took part in the filming of the television show Luka and Léo. During this episode, he had the opportunity to answer a fascinating question posed by Charles: “How does a brain work?”
With his expertise in neuroscience, Felipe captivated the audience by explaining the complex mechanisms of the human brain. He discussed key concepts such as neurons, the nerve cells that transmit electrical signals, and how different parts of the brain work together to process information, regulate emotions, and control our daily actions.

Among the five most notable scientific breakthroughs of 2024, according to Le Soleil, is the remarkable discovery by Dr. Alexandre Caron’s team, one of our own researchers. Their work opens new chapters in the history of science with a major advancement: they may have uncovered the key behind the appetite-suppressing effects of Ozempic.
It was known that GLP-1 and molecules mimicking it could slow the transit of food through the digestive system, possibly also acting on the brain, and thus, it was thought, suppress hunger. Dr. Caron and his team discovered that the mechanism is far more complex and fascinating. They also identified new, previously unknown populations of neurons that play an important role in regulating appetite.
