AI-Powered Eye Scans Could Revolutionize Dementia Diagnosis
The NeurEYE research team in Scotland is developing a groundbreaking method to diagnose dementia through eye scans powered by artificial intelligence. As reported by BBC News, the team is training AI software to detect early signs of dementia using retina photographs. Remarkably, the eyes can show clues about the disease well before other symptoms appear, offering a promising approach to early intervention.
The team has access to nearly one million retinal images from opticians across Scotland, creating the largest dataset of its kind globally. Their AI technology analyzes blood vessels in the eye to identify potential markers of dementia.
“The eye can tell us far more than we thought possible,” said Baljean Dhillon, professor of Clinical Ophthalmology at the University of Edinburgh and NeurEYE co-lead. “The retina holds a whole wealth of information and is a biological barometer of our brain health. We can see the retina with the simple, inexpensive equipment found in every high street in the UK and beyond.”
He added, “Something very simple like a photograph of a retina can now be harnessed to potentially predict brain change later on in life.”
While there is no cure for dementia yet, early detection allows doctors to intervene sooner, improving management of the condition. Dementia, which can impair memory, thinking, and speech, affects one in 14 people aged 65 and one in six aged 80, according to Dementia UK. With such a significant portion of the population at risk, deploying this technology could have a major impact.
The NeurEYE researchers aim to have a prototype ready by the end of this year, with plans for a wider rollout to UK opticians by 2026. While concerns about artificial intelligence often focus on its impact on employment, this project highlights the technology’s potential to transform healthcare and save lives.
