Abstract
Introduction: Worldwide around 400 million people suffer from hearing loss. There is increasing evidence that hearing loss is a modifiable risk factor for cognitive decline. However, several risk factors for cognition are common in hearing-impaired individuals, including vestibular dysfunction, anxiety, and depression. This study aimed to explore the effect of hearing loss on cognitive functioning in older adults, considering the effects of vestibular function, anxiety, and depression on cognitive performance.
Method: A cross-sectional study was performed on 42 subjects with moderate-to-severe sensorineural hearing loss (SNHL) and 42 matched normal-hearing controls. Matching was based on the following factors; sex, age, education level, level of anxiety and depression, and vestibular function. The test battery consisted of a cognitive assessment (Repeatable Battery for the Assessment of Neuropsychological Status adjusted for the Hearing Impaired [RBANS-H]), hearing assessment (Pure Tone Average and speech-in-noise testing), and vestibular assessment (video Head Impulse Test [vHIT]). Depression and anxiety were evaluated using the Hospital Anxiety and Depression Scale (HADS) and Beck Depression Inventory (BDI) questionnaires.
Results: A significantly lower total cognitive (RBANS-H) score was observed in the group with SNHL compared to controls (100.93 [12.94] vs. 108.88 [10.47], p = 0.003). The difference among both groups was most pronounced in the subdomains Visuospatial/Constructional (92.90 [16.32] vs. 103.12 [12.83], p = 0.002) and Attention (96.62 [12.52] vs. 104.02 [11.81], p = 0.007). The other subdomains Immediate Memory, Language, and Delayed Memory did not differ significantly between the groups with SNHL and the normal-hearing controls.
Conclusion: The results of this study indicate that hearing loss negatively affects cognitive functioning, even in older adults with normal vestibular function.
期刊介绍：
''Audiology and Neurotology'' provides a forum for the publication of the most-advanced and rigorous scientific research related to the basic science and clinical aspects of the auditory and vestibular system and diseases of the ear. This journal seeks submission of cutting edge research opening up new and innovative fields of study that may improve our understanding and treatment of patients with disorders of the auditory and vestibular systems, their central connections and their perception in the central nervous system. 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.
