Visual Impairment May Up Risk For Dementia In Older Women

Visual impairment -

The cohort study included 1,061 women aged 66 to 84 years old, 183 of whom had objective visual impairment. It was identified through questionnaires and visual acuity measurements with three threshold levels: 20/40 or worse, 20/80 or worse, and 20/100 or worse in at least one eye. Mean follow-up after enrollment was 3.8 years. The researchers found that of the 183 women enrolled with objective visual impairment, 42 (4.0 percent) were ultimately classified as probable dementia and 28 (2.6 percent) were classified as MCI, which did not progress to dementia.
