Vision Loss In Senior Citizens May Signal Risk Of Dementia: Study
[ad_1]
Sight loss in people over 71 years old may be linked to dementia, suggests a new study. The researchers at the University of Michigan in the US analysed data from nearly 3,000 US citizens over 71 years old. They tested the participants' eyesight and recorded their scores for short-distance vision, long-distance vision and how well they were able to distinguish objects against different backgrounds.
The findings, published in the Journal of the American Medical Association (JAMA) Ophthalmology, showed that participants with sight loss were more likely to have dementia compared to people with no problems with their vision. Up to 40 per cent of dementia cases could be influenced by 12 risk factors which we may prevent or influence, such as smoking, high blood pressure and hearing loss. Sight loss is not currently one of these 12 important risk factors, but the new evidence suggests that there is a link between sight loss and dementia, the researchers said. cre Trendi
