Visual Impairment Tied to Increased Dementia Risk in Older Women
05/08/2020
Older women with objective visual impairment are likely to develop dementia or mild cognitive impairment, a secondary analysis of data from the Women’s Health Initiative (WHI) suggests, according to a Reuters report.
Researchers examined data on 1,061 women enrolled in the WHI Sight Examination and WHI Memory Study from 2000 to the present. They looked at incident dementia or mild cognitive impairment (MCI) based on annual cognitive testing and clinical assessment for three thresholds of impaired visual acuity at baseline: 20/40, 20/80, and 20/100 and self-reported visual impairment.
