Learn about the relationship between vision problems and dementia according to science

In a world where life expectancy is constantly increasing, health in old age becomes increasingly important. In addition to the well-known heart and muscle problems, another risk that increases with age is dementia. Health researchers have dedicated themselves to studying various factors that can increase the onset of dementia, one of which is vision problems.

Dementia: 40% of cases are caused by these habits

Recent research published in JAMA Ophthalmology suggests an increased likelihood of dementia among older adults with eye problems. This study suggests an interesting relationship: the number of vision problems appears to be directly related to the risk of dementia.

How was the study on vision and dementia developed?

The study was conducted by a team of experts from the University of Michigan and was based on data from the 2021 National Health and Aging Trends Study.

This research, which contains information from 2,967 participants over the age of 71, suggests a relationship between all types of vision problems and a higher incidence of dementia, including Alzheimer’s disease.

What are the most important vision problems studied?

Among the vision factors the study took into account: distance visual acuity, also known as distance vision acuity, which measures the human eye’s ability to see objects clearly at a distance; near visual acuity, which evaluates how well a person can see up close; Contrast sensitivity, which measures the ability to distinguish between an object and the background on it, or between two similar colors.

Is it possible to prevent dementia by treating vision problems?

Researchers from the University of Michigan suggest that treating visual problems could be a crucial factor in preventing dementia. They point out that the loss of visual stimuli can cause a decrease in mental engagement, which in turn leads to an increased likelihood of developing dementia. Thus, the study suggests that by maintaining visual health, it is possible to reduce the risk of developing dementia in old age.
