Abstract

Purpose of review: Hearing loss is one of the largest modifiable risk factors for developing dementia, accounting for up to 9% of the overall modifiable risk. The neuropsychologic and psychosocial impacts of hearing loss are becoming increasingly appreciated. The objective of this review is to explore the recent literature regarding the cognitive and behavioral effects of hearing loss and the role of hearing rehabilitation, particularly in older adults.

Recent findings: Cognitive decline may begin while patients have subclinical hearing loss, earlier than previously thought. Hearing rehabilitation, either via hearing amplification, middle ear surgery, or cochlear implantation, likely plays a role in preventing or slowing the rate of cognitive decline in patients with hearing loss. Hearing loss can increase the likelihood of social isolation, loneliness and depression in older adults, but it is unclear at this time what effect hearing rehabilitation has on these domains.

Summary: Hearing loss is one of the largest modifiable risk factors for cognitive decline, and hearing rehabilitation can play a significant role in preserving cognitive function. Understanding the cognitive and psychosocial impact of hearing loss can help facilitate the development of approaches for prevention and treatment.
