Study: The eye can predict dementia 12 years before it is diagnosed

Norfolk In England, all were in good health when the study began, and during the follow-up period, 537 participants were diagnosed with depression At the start of the study, the participants underwent a visual sensitivity test in which they were asked to press a button as soon as they saw a triangle forming between moving dots. It showed that people who developed symptoms of dementia were slower to find this triangle compared to others

It can beFor visual problems An early sign of cognitive decline, as toxic deposits known as “amyloid plaques” in Alzheimer’s disease are believed to begin to affect the areas of the brain that are responsible for vision before they affect memory areas, showing other problems related to Alzheimer’s disease, including poor contrast sensitivity (shape discrimination) and difficulty distinguishing colors especially the blue-green spectrum.

People with dementia may have difficulty controlling their eye movements, making them more prone to visual disturbances. This problem leads to daily challenges such as getting to know new people or dealing with their environment.

The research suggests that Increased eye movements Things like watching TV​​​​​​​​​​​​ or reading can improve memory performance. Other studies have also found that rapid eye movements (two times per second) can improve autobiographical memory (the story of your life).

Despite promising results, the use of eye tracking technologies as a diagnostic tool is still limited outside laboratories due to high cost and difficulty of use.

The development of less expensive and easier to use eye tracking devices could open the door to earlier diagnosis of Alzheimer’s disease through eye tests.

The study shows that vision can be a window to a deeper understanding of brain health, which adds hope to an early diagnosis of dementia through simple visual tools.
