Abstract

Objectives: Hearing loss is recognized as a potentially modifiable risk factor for dementia in midlife. This study aimed to investigate the association between rehabilitation methods and dementia risk in patients with severe to profound hearing loss.

Design: Using the nationwide population data from South Korea, individuals with severe to profound hearing loss were identified. Individuals aged 40 to 79 were then divided into 3 groups according to the type of auditory rehabilitation they received in the period between 2005 and 2010, namely cochlear implant (CI), hearing aid (HA), or no rehabilitation (NR). No hearing loss (NHL) group (with normal hearing) consisted of individuals without hearing loss. Dementia incidence was followed up to 2022.

Results: The study involved 649 individuals in the CI group, 35,076 in the HA, 16,494 in the NR, and 1,280,788 in the NHL group. The groups that received auditory rehabilitation (HA and CI groups) had a significantly reduced risk of dementia compared with the NR group, with the CI group showing the most pronounced reduction. The CI group demonstrated a lower risk of dementia than the HA group and had a similar dementia risk to the NHL group.

Conclusions: In individuals with severe to profound hearing loss, rates of dementia were lower in CI users than in HA users. Moreover, the risk of dementia in those undergoing CI surgery is comparable to that of individuals with normal hearing.

人工耳蜗植入与重度听力损失患者痴呆发生率降低相关

目的：听力损失被认为是中年痴呆的一个潜在的可改变的危险因素。本研究旨在探讨重度至重度听力损失患者康复方法与痴呆风险之间的关系。设计：利用韩国全国人口数据，确定重度至重度听力损失个体。将年龄在40 ~ 79岁之间的受试者根据其2005 ~ 2010年间接受听觉康复的类型分为3组，分别为人工耳蜗（CI）、助听器（HA）和无听觉康复（NR）。无听力损失组（NHL）由听力正常的个体组成。痴呆发病率随访至2022年。结果：该研究涉及CI组649人，HA组35,076人，NR组16,494人，NHL组1,280,788人。与NR组相比，接受听觉康复的组（HA组和CI组）患痴呆的风险显著降低，其中CI组的降低最为明显。CI组痴呆风险低于HA组，与NHL组痴呆风险相似。结论：在重度至重度听力损失的个体中，CI使用者的痴呆率低于HA使用者。此外，那些接受CI手术的人患痴呆的风险与听力正常的人相当。

期刊介绍： From the basic science of hearing and balance disorders to auditory electrophysiology to amplification and the psychological factors of hearing loss, Ear and Hearing covers all aspects of auditory and vestibular disorders. This multidisciplinary journal consolidates the various factors that contribute to identification, remediation, and audiologic and vestibular rehabilitation. It is the one journal that serves the diverse interest of all members of this professional community -- otologists, audiologists, educators, and to those involved in the design, manufacture, and distribution of amplification systems. The original articles published in the journal focus on assessment, diagnosis, and management of auditory and vestibular disorders.
