Numerous screening tests are available to identify cases of cognitive impairment ( 17). A patient's cognitive profile is increasingly taken into account in auditory rehabilitation in cochlear implant patients ( 9, 12– 14) and speech recognition outcomes among cochlear implant recipients are better for those with better cognitive ability ( 15, 16). Routine hearing assessments depend on cognitive function tests of speech recognition, for example, are impacted by cognitive factors ( 11). There is a growing interest in neurocognitive testing in settings outside psychologic or psychiatric ones ( 9, 10), particularly in hearing rehabilitation settings. One survey of people with cognitive impairment attending a memory clinic reported that around 85% had a hearing impairment ( 8). Age-related hearing loss is associated with increased risk for cognitive impairment, increasing likelihood of comorbidity of hearing loss with cognitive impairment ( 3– 7). Hearing loss and dementia are commonly co-morbid. ![]() Currently, approximately 430 million people live with disabling hearing loss ( 1), while 55 million people worldwide have dementia ( 2). Based on the demographic data normative data were developed by a regression-based approach.Ĭonclusion: The MoCA-HI is a cognitive screening test which is suitable for people with hearing impairment.Īge-related hearing loss and dementia are among the most common chronic diseases in old age. Higher age ( p < 0.001), male sex ( p = 0.009) and lower education ( p < 0.001) were associated with a lower overall MoCA-HI score. Test-retest reliability of the MoCA-HI was high ( p < 0.001). There was no difference between the MoCA and the MoCA-HI performance in group 1 ( p = 0.12), whereas individuals of group 2 performed significantly better on the MoCA-HI than on the standard MoCA ( p < 0.001). In contrast, group 1 performed significantly better than group 2 on the standard MoCA ( p < 0.001). Results: No significant group difference between group 1 and 2 was found in the MoCA-HI total score ( p = 0.05). Additionally, all participants performed the standard MoCA (version 8.2). Material and methods: The German MoCA-HI was tested in 94 participants with normal or mild hearing impairment (group 1: 4PTA ≤ 40 dB on the better hearing ear) and 81 participants with moderate to profound hearing loss (group 2: 4PTA > 40 dB on the better hearing ear). Objective: The aim of the present study was to compare cognitively healthy participants with and without hearing loss, to examine the impact of age, sex, educational level and degree of hearing impairment on the German MoCA-HI performance, and to develop normative data. We report the first evaluation of a German language version of the Montreal Cognitive Assessment-Hearing Impaired version (MoCA-HI).
