Abstract

Background

Over 55 million people worldwide are living with dementia. The rate of cognitive decline increases with age, and loss of senses may be a contributing factor.

Objectives

This study aimed to analyze hearing, olfactory function, and color vision in patients with dementia.

Materials and methods

The sample comprised 40 patients with dementia and 37 cognitively normal controls aged 41–85 years. All participants underwent conventional pure-tone audiometry and a screening version of the Hearing Handicap Inventory for Adults, the Odorized Markers Test of olfactory function and the Ishihara color vision test. The effects of comorbidities and lifestyle factors were also assessed.

Results

Patients with dementia had significantly worse hearing at almost all frequencies tested and significantly greater olfactory impairment than cognitively normal controls. Color vision impairment was found in less than 8% of the sample, with no significant difference between the groups. Impairment of two senses (hearing and olfaction) was significantly more common in patients with dementia than in controls.

Conclusion

Individuals with dementia were found to have sensory decline, namely hearing and olfactory impairment. Color vision was rarely impaired in the sample. Participants with dementia tended to have more multisensory impairments than controls.

老年痴呆患者感觉功能障碍的评估。

背景：全世界有超过5500万人患有痴呆症。认知能力下降的速度随着年龄的增长而增加，而感官的丧失可能是一个促成因素。目的：本研究旨在分析痴呆患者的听力、嗅觉功能和色觉。材料与方法：40例痴呆患者和37例认知正常对照，年龄41 ~ 85岁。所有的参与者都接受了传统的纯音测听和筛查版的成人听力障碍量表，嗅觉功能的气味标记测试和石原色觉测试。还评估了合并症和生活方式因素的影响。结果：痴呆患者在几乎所有频率的听力测试中都比认知正常的对照组明显更差，嗅觉损伤也明显更大。色觉障碍在不到8%的样本中被发现，两组之间没有显著差异。两种感觉（听觉和嗅觉）的损伤在痴呆患者中明显比对照组更常见。结论：痴呆患者存在感觉功能下降，即听觉和嗅觉障碍。色觉在样本中很少受损。痴呆患者往往比对照组有更多的多感觉障碍。

期刊介绍： Journal of Otology is an open access, peer-reviewed journal that publishes research findings from disciplines related to both clinical and basic science aspects of auditory and vestibular system and diseases of the ear. This journal welcomes submissions describing original experimental research that may improve our understanding of the mechanisms underlying problems of basic or clinical significance and treatment of patients with disorders of the auditory and vestibular systems. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines. Journal of Otology welcomes contributions from scholars in all countries and regions across the world.
