Hearing interventions for adult with cognitive decline: A scoping review

Hearing interventions are increasingly recognized as an important part of dementia care because hearing loss is closely linked to cognitive decline. Although earlier reviews, such as Dawes et al. (2019), examined sensory interventions in general, they did not focus specifically on the current range of hearing interventions used for people with cognitive impairment. Common approaches, such as hearing aids, personal sound amplification devices, communication training, and caregiver support, have shown inconsistent effects on cognitive, hearing, psychological, functional, quality-of-life, and caregiver burnout outcomes.This review aims to determine whether hearing interventions have an effect on individuals with cognitive impairment and to address gaps in the existing evidence.
