A team from the University of Florida, having analyzed retinal scans from over 40,000 people, determined that these images can serve as an early indicator of Alzheimer’s risk. By employing artificial intelligence, they successfully pinpointed major risk factors such as hypertension and tobacco use.
The research, carried out by scientists at the University of Florida, revealed that a routine retinal photograph can act as a useful means of detecting Alzheimer’s risk factors well before initial symptoms manifest. The outcomes of this study were published in the esteemed Journal of Alzheimer’s Disease (JAD).
In their work, the investigators utilized AI to examine retinal images from more than 40,000 participants. The algorithm they created managed to recognize characteristics linked to an increased likelihood of developing Alzheimer’s. These characteristics included:
- elevated blood pressure
- smoking
- alcohol intake
- sleep disruptions
Special attention was directed toward alterations in the retinal blood vessels and the optic nerve region.
As the researchers point out, Alzheimer’s disease evolves over many years, and the majority of current diagnostic approaches can only identify it at advanced stages. The retina, which is intimately connected to the nervous system, can mirror accumulated bodily changes that take place long before memory issues become apparent.
The scientists suggest that evaluating eye photographs could become a straightforward and economical strategy for early identification of those at higher risk. This would enable timely advice on lifestyle adjustments and other preventive actions that could help slow the disease’s advancement.
It was previously reported that a ketogenic diet may shield the brain from conditions like Alzheimer’s and Parkinson’s diseases.
