Video-oculography and Parkinson's Disease

This study uses eye-tracking technology (video-oculography) to explore eye movement abnormalities in patients with Parkinson's disease. Eye movements are controlled by brain regions affected by Parkinson's, and measuring them precisely may help improve diagnosis and track disease progression. **You may be eligible if:** - You have a confirmed diagnosis of idiopathic (typical) Parkinson's disease - Your Parkinson's is in an early to moderate stage (Hoehn and Yahr score 1–3) - You have had a brain MRI and a dopamine scan (DaTSCAN or F-DOPA PET) confirming the diagnosis - Your cognitive function is normal or only mildly impaired - You speak French sufficiently - You have a caregiver **You may NOT be eligible if:** - You have a psychiatric condition other than mild anxiety or depression - You have significant neurological comorbidities - Your brain MRI shows significant vascular disease or another brain condition - Your symptoms suggest a different type of Parkinsonism (not typical Parkinson's disease) - You have major cognitive impairment or dementia Talk to your doctor to see if this trial is right for you.
