One of the topics that scientists have worked on the most in recent years is: Dementia stands out as. A new, long-term scientific study makes the diagnosis of dementia possible from the age of 12 by monitoring changes in vision.

in Norfolk, England 8 thousand 623 The research, which started with healthy participants, spread over many years. At the end of the study participants 537 of He was observed to develop dementia. The researchers, who regularly tested the visual skills of the participants, came across interesting results.

People who develop dementia respond more slowly

At the beginning of the study, participants were asked to watch dots move on a screen and create a triangle each time the dots formed a triangle. push the button was asked. Reaction time in this visual sensitivity test the slower one It turns out that they are more susceptible to developing dementia.

According to researchers, the reason for this situation Alzheimer’s It may be that toxic amyloid plaques associated with diabetes first form in the part of the brain responsible for vision. In this case, as the disease progresses, it begins to affect the memory-related parts of the brain. Visual sensitivity testing can be an important diagnostic tool in this regard.

Alzheimer’s or dementia patients vision skills issues It has been revealed before. People with these disorders cannot clearly distinguish the edges of objects and begin to lose their perception of contrast. Furthermore, their responses to ‘distracting stimuli’ change over time.

The research has been published on PubMed.
