Can Eye Exams Play an Important Role in Early Detection of Alzheimer's and Parkinson's?

Can eyes really provide 'Windows to the Brain?' A Canadian group is working on a study that is aiming to prove just that.

Chris Hudson, a scientist and optometrist by training and a professor at the University of Waterloo school of optometry and vision science, is developing an entirely new way to diagnose Parkinson’s and other neurodegenerative diseases, like Alzheimer’s and ALS. Hudson says the retinas of patients who suffer from Alzheimer’s, Parkinson’s and other neurodegenerative diseases appear to undergo small changes before typical symptoms show up. Evidence is pointing to possible nerve death in the retina of the eyes, as a sign that the same may be happening in the brain.

Hudson is not only part of the team heading up this research, but he is also a patient, having been diagnosed with Parkinson's Disease thirteen years ago. Being both a patient and scientist, Hudson is hopeful that a breakthrough is finally on its way.

“The payoffs are potentially incredible. If we can do this, it will have a huge impact on the management of all these diseases.”
