Although the rates of occurrence of age-related diseases, including presbycusis and cognitive disorders, have increased with an increase in the geriatric population, the relationship between these two conditions remains unclear.
To investigate the association between presbycusis and cognitive disorder.
A retrospective review of patient medical records was conducted at a single tertiary university hospital. This study enrolled 399 patients aged ≥65 years who were prescribed hearing aids for the chief complaint of hearing loss. For main outcomes and measures we used audiograms, the Korean Mini-Mental State Examination, and the Global Deterioration Scale (GDS).
Of the 399 patients who were prescribed hearing aids for presbycusis, 45 (11.3%) had dementia and 354 (88.7%) did not have dementia. When the cognitive disorder group was divided into mild (1-4) and severe (5-7) subgroups based on the GDS scores, the threshold of hearing loss was significantly higher in the severe group than in the mild group (p < 0.05). The prevalence of dementia was significantly higher in patients with hearing loss for ≥10 years than in patients with hearing loss for <10 years (p < 0.05).
Presbycusis and cognitive disorder are correlated. More severe and prolonged hearing loss is associated with a higher prevalence of cognitive disorder.
尽管包括老年性耳聋和认知障碍在内的与年龄相关疾病的发生率随着老年人口的增加而上升，但这两种疾病之间的关系仍不明确。
研究老年性耳聋与认知障碍之间的关联。
在一家单一的三级大学医院对患者病历进行回顾性研究。本研究纳入了399名年龄≥65岁、因听力损失为主诉而佩戴助听器的患者。对于主要结局和测量指标，我们使用了听力图、韩国简易精神状态检查表和总体衰退量表（GDS）。
在399名因老年性耳聋而佩戴助听器的患者中，45名（11.3%）患有痴呆症，354名（88.7%）没有痴呆症。当根据GDS评分将认知障碍组分为轻度（1 - 4）和重度（5 - 7）亚组时，重度组的听力损失阈值显著高于轻度组（p < 0.05）。听力损失≥10年的患者痴呆症患病率显著高于听力损失<10年的患者（p < 0.05）。
老年性耳聋与认知障碍相关。更严重和更持久的听力损失与更高的认知障碍患病率相关。
