The participants, who were all older than 71, were then screened for dementia using the Dementia Screening Interview, the study said. In people with distance visual impartment, that jumped to 19.5%; 21.5% for near visual impairment; and 32.9% for people who had moderate to severe visual impairment or were blind, according to the study. Another factor that might lead to the correlation is a possible decrease in opportunities and community participation that could come with vision loss, Silverman said. “When it comes to vision impairment and blindness, an estimated 80 plus percent is either preventable or even reversible,” he added. “If you notice that you have vision that is starting to be impaired, get it checked out.”But not every case of vision loss is treatable.
