Association of Visual Impairment With Risk of Incident Dementia in a Women’s Health Initiative Population

Association of Visual Impairment With Risk of Incident Dementia in a Women’s Health Initiative... Key PointsQuestionIs visual impairment associated with women’s risk for developing dementia? FindingsIn this cohort study of 1061 older women, baseline objectively measured visual impairment was associated with a 2- to 5-fold increased risk of dementia over a median 3.8 years of follow-up; 3.1% of participants without objective visual impairment developed dementia vs 8.2% of those with visual acuity of 20/40 or worse. More severe visual impairment was associated with increasingly elevated risk of incident dementia. MeaningThese results suggest that visual impairment may be a risk factor for dementia; findings are limited by sample size, and more research is needed in a larger population. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png JAMA Ophthalmology American Medical Association

Abstract

Key PointsQuestionIs visual impairment associated with women’s risk for developing dementia? FindingsIn this cohort study of 1061 older women, baseline objectively measured visual impairment was associated with a 2- to 5-fold increased risk of dementia over a median 3.8 years of follow-up; 3.1% of participants without objective visual impairment developed dementia vs 8.2% of those with visual acuity of 20/40 or worse. More severe visual impairment was associated with increasingly elevated risk of incident dementia. MeaningThese results suggest that visual impairment may be a risk factor for dementia; findings are limited by sample size, and more research is needed in a larger population.
