Dual sensory impairment (DSI) refers to the presence of both visual and hearing impairments in an individual, which can lead to significant difficulties in communication, daily activities, and overall quality of life. Abnormal changes to vision and hearing in later life are often mistaken for normal aging, and decrements to these senses result in poorer quality of life for those affected and their significant others.
Those with DSI may have difficulty communicating with others, performing daily activities, and be at a higher risk of falls and other injuries.
A May 2022 study found that DSI was associated with a 160% increased risk for all-cause dementia and a 267% increased risk for Alzheimer’s disease. The good news is that studies also show that people who receive treatment for DSI have a higher quality of life and a lower risk of death than those who don’t.
