A new doctoral study suggests changes in eye movements could indicate the beginning stages of Alzheimer’s disease, even before noticeable memory problems appear. Researchers found alterations in how individuals move their eyes correlated with both Alzheimer’s and mild cognitive impairment. By measuring these eye movements, it may be possible to gain early insights into the disease’s development. The research, conducted by Sanna Hannonen, a medical licentiate, demonstrated the ability to detect these changes in very early stages. This discovery could potentially lead to earlier diagnosis and intervention for those at risk. The study highlights the potential of eye-tracking technology as a non-invasive tool for identifying early biomarkers of Alzheimer’s.
