Hearing and vision loss are independently associated with dementia, but the impact of dual sensory impairment (DSI) on dementia risk is not well understood..
..DSI was significantly associated with higher risk of all‐cause dementia (hazard ratio [HR] = 1.86; 95% confidence interval [CI] = 1.25‐2.76) and Alzheimer’s disease (HR = 2.12; 95% CI = 1.34‐3.36). Individually only visual impairment was independently associated with an increased risk of all‐cause dementia (HR = 1.32; 95% CI = 1.02‐1.71).
Older adults with DSI are at a significantly increased risk for dementia. Further studies are needed to evaluate whether treatments can modify this risk
