Large retrospective studies have demonstrated that visual impairment is a risk factor for developing cognitive impairment, including dementia.Cataracts, age-related macular degeneration and ...

The PAF of dementia from at least one vision impairment was 19%, with contrast sensitivity (15%) linked to the strongest PAF, followed by near acuity (9.7%) and distance acuity (4.9%).

In total, the researchers estimated that 19 percent of all dementia cases could be attributable to at least one type of visual impairment, with poor contrast sensitivity showing the strongest ...
