Elderly people suffering from visual impairment, the risk of dementia (dementia) than their peers with good eyesight. This is according to American researchers.
The scientists studied 625 older Americans and came to the following conclusion. In subjects who complained of poor eyesight During the eight years of observation Dementia It evolved much more often than those who had no such problems. During follow-up, 168 participants developed Alzheimer's disease and other forms of dementia. Among them are at least ten per cent rated their vision as "excellent".
In another group of 31 percent of people with good eyesight We have full clarity of mind. The scientists also found out that the risk of dementia higher in those people who are trying to improve vision, refused treatment. When the subjects were receiving treatment, the level of risk is reduced.
But the findings, published in the "American Journal of Epidemiology" not yet prove that contribute to eye problems dementia Or that the care of vision can develop cognitive functions. This is only one of the hypotheses that require further research and observations.
Dr Mary Rogers, one of the members of the research team also noted that, while not entirely clear how these two phenomena are linked. According to one version, blurred vision It leads to a decrease in social activity. It is less contact with the outside world. His brain does not receive the necessary load, and this, in turn, may increase the risk of dementia .
Dr. Rogers urges to be more attentive to the state of your health, do not run the disease. If you believe that your vision has recently become worse, do not delay a visit to an ophthalmologist!
