A study conducted by the University of South Australia has gone against the common literature relating poor eyesight to brain decline, finding that cognitive tests can misdiagnose older people with age-related vision decline with cognitive decline by up to 25 percent.
“A mistaken score in cognitive tests could have devastating ramifications, leading to unnecessary changes to a person’s living, working, financial or social circumstances,” said Anne Macnamara, the lead author of the study.
