“…Therefore, our results are likely to be conservative, particularly for cross-sectional relationships, as most participants who had difficulty seeing the cognitive tests were either excluded or accounted for in the test scoring. This limitation highlights the importance of previous research efforts to develop cognitive tests for older adults with sensory impairments (31)(32)(33).…”

Background An association between visual impairment and cognitive outcomes has been documented, but there is limited research examining this relationship using multiple measures of vision. Methods Participants included non-demented individuals in Year 3 of the Visual impairment was assessed using visual acuity, contrast sensitivity, and stereo acuity. Cognitive function was defined using the digit symbol test and the Modified Mini-Mental State Examination (3MS). Incident cognitive impairment was defined as a 3MS score <80 or a decline >5 points following Year 3. Linear mixed effects models examined longitudinal associations adjusting for year, age, sex, race, education, smoking, depression, diabetes, study site, as well as interaction terms between the vision parameters and years in study, between baseline age and years in study, and quadratic terms of baseline age and years in study. Discrete Cox regression models examined the risk of incident cognitive impairment. Results Analyses included 2,444 participants (mean age = 74). Visual acuity, contrast sensitivity, and stereo acuity impairments were not associated with statistically significant changes in annual digit symbol test scores over 7 years of follow-up, as compared to those without these impairments. However, visual acuity, contrast sensitivity, and stereo acuity impairments were associated with greater declines in annual 3MS scores over 9 years. Participants with impaired visual acuity, contrast sensitivity, and stereo acuity had a greater risk of incident cognitive impairment. Conclusions Our results suggest that visual acuity, contrast sensitivity, and stereo acuity impairments may be risk factors for cognitive decline.

“…Given the reliance of MoCA items on either hearing or vision function, the MoCA test paradigm is not suitable for adaptation for those with dual sensory impairment. Alternative cognitive screening tests for those with dual sensory impairment are available or in development, based, for example, on touch33 34 or smell 35…”

Protocol for the development of versions of the Montreal Cognitive Assessment (MoCA) for people with hearing or vision impairment

et al. 2019

IntroductionHearing and vision impairments are highly prevalent among older adults and impact commonly used cognitive assessment tools for the identification of dementia. Adaptations of such tests for people with hearing or vision impairment have not been adequately validated among populations with such sensory impairment.Methods and analysisWe will develop two versions of the Montreal Cognitive Assessment (MoCA) for people with acquired hearing impairment (MoCA-H) or vision impairment (MoCA-V). The MoCA-H and MoCA-V will exclude the existing MoCA items that are presented in spoken or visual format, respectively, and include new suitably adapted items. Participants (n=792) with combinations of hearing, vision and cognitive impairment will complete standard or adapted versions of the MoCA across three language sites (English, French and Greek). Development of the MoCA-H and the MoCA-V will be based on analysis of adapted and standard MoCA items following model-based development to select the combination of items for the MoCA-H and MoCA-V that provide optimal sensitivity and specificity for detection of dementia.Ethics and disseminationThe study has received ethical approval from respective centres in the UK, France, Greece and Cyprus. The results of the study will be disseminated through peer-reviewed publication, conference presentations, the study website (https://www.sense-cog.eu/), the SENSE-Cog Twitter account (@sense_cog) and the MoCA test website (https://www.mocatest.org/). The main outputs of the study will be versions of the MoCA that are appropriate for use with adults with acquired hearing or vision impairment and will contribute significantly to the clinical care of older people.
