Introduction to Supplement Issue: Sensory loss in Alzheimer's disease and related dementias

Sensory impairments (e.g., decreased function in hearing, vision, olfaction, and other senses) may be risk factors for or early markers of Alzheimer's disease (AD) and related dementias (ADRD). Sensory impairments are common and have a large impact on wellbeing. Furthermore, they are clinically detectable and, often, treatable, and could be leveraged to identify and prevent AD/ADRD. This Supplement Issue brings together original research articles, reviews, and thought papers regarding the links between sensory impairments and cognitive health. Together, this work highlights the significant opportunities to use sensory information and remediation for earlier diagnosis, treatment, and prevention of dementia.
