Eye imaging to detect early signs of brain diseases

Researchers are studying whether special eye imaging can detect early warning signs of neurodegenerative diseases—conditions that affect the brain and nervous system, like Alzheimer's disease, Parkinson's disease, and others. The study uses advanced cameras to take detailed pictures of blood vessels in the back of your eye, looking for tiny changes that might mirror what's happening in your brain. They believe the eye might show signs of these diseases before symptoms appear or get worse.

Right now, doctors don't have a simple, early screening tool for brain diseases—by the time symptoms show up, significant damage may have already occurred. This research aims to prove that eye imaging could become an easy, non-invasive way to catch these diseases much earlier, when treatment might be more helpful.
