Is there a connection between visual impairment and cognitive ability in older adults? Scientists and researchers don't know for sure why vision problems affect cognitive decline, but studies indicate that seniors who have cataract surgery to improve their vision are more likely to stay active and independent, and are less likely to deal with depression, lonliness and a reduction in cognition.
And, studies suggest that the reverse may also be true. It is likely that seniors with reduced mental function are less likely to receive cataract surgery.
