A recent study conducted by Dr. Mary Rogers and her contemporaries from the University of Michigan have found a possible correlation between poor vision and cognitive functioning of the brain in senior citizens.
According to their research, elderly people with untreated sight problems have a greater chance of developing dementia over the next eight and a half years than those possessing normal vision.
The study was composed of data collected from 625 subjects who were 65 or older with previously proven normal cognitive abilities and data collected from medicare files. The collective material was investigated for an average of 8 1/2 years.
Study participants who reported excellent or good eyesight at the start of the study were at a 63 per cent lesser risk of developing dementia than those with average or poor vision. Study subjects with poor eyesight who had never visited an eye specialist increased their chances of developing a cognitive disorder by five times and had a 9.5 times higher chance of having Alzheimer’s disease.
The research team is unable to explain the exact reason why dementia is linked to poor eyesight. The assumption is that the inactiveness caused by poor vision could be a possible reason.
