Scottish researchers are developing an AI tool for high-street opticians to identify early signs of dementia. Retina photographs can indicate brain health, and AI analysis can detect disease signs before symptoms appear.
The NeurEYE team from the University of Edinburgh, along with researchers from Glasgow Caledonian University, has amassed a vast eye scan database. Their AI algorithm evaluates blood vessel health in the eye, potentially revealing neurogenerative diseases.
The eye's tiny blood vessels can show conditions earlier than other body parts. Professor Baljean Dhillon mentioned that "the eye can reveal more than expected" and that a simple retina image could predict brain health changes.
Early dementia diagnosis is crucial for treatment. Dementia UK states that the condition affects many older adults, with Alzheimer's disease causing memory loss, confusion, and speech difficulties.
Engineer David Steele shared how early diagnosis could have eased his family's struggles with his mother's Alzheimer's. Detecting such conditions sooner can significantly impact families and provide time for preparation.
Specialist optometrist Ian Cameron highlighted the eye's role as a "window to the whole body," detecting various health issues. Regular eye check-ups can lead to improved health outcomes by identifying conditions early.
The project aims to introduce a prototype later this year, with nationwide implementation planned for 2026, offering opticians the technology to improve dementia detection and patient care.
