The World Health Organization (2019) predicts that the number of individuals with AMD will increase 1.2-fold from 2020 (roughly 195 million) to 2030 (roughly 243 million). Low vision (LV) has been described as a decline in visual functions that alters the ability to complete visual tasks, and that cannot be treated with corrective or contact lenses, or other surgical or medical interventions ( Corn and Erin, 2010). Some visual functions change as a result of visual pathologies, such as age-related macular degeneration (AMD), glaucoma or diabetic retinopathy, all of which can cause low vision ( Wittich and Gagné, 2016). The present study is relevant to clinicians who are assessing the cognitive status of older adults, such as neuropsychologists, because it highlights the importance of considering low vision when administering neuropsychological tests, especially to persons who have not yet received rehabilitation for their visual impairment.Ĭhanges in vision, such as the inevitable arrival of the need for reading glasses in middle age (presbycusis) are expected as a part of the normal aging process ( Haegerstrom-Portnoy et al., 2002) however, there are eye diseases associated with aging that can further impair the visual abilities of older adults ( Wong et al., 2014). Correlations between contrast sensitivity and memory, as well as between global cognition and visual aid use remained significant after controlling for age and education. Results and discussion: Correlations among global cognition and visual aid use, memory and reading speed, memory and contrast sensitivity, memory, and visual aid use, and between executive functions and contrast sensitivity were significant. They underwent vision (reading acuity, reading speed, contrast sensitivity), hearing (audiogram, speech-in-noise perception) and cognitive (global cognition, memory, executive functions) testing, and demographic information was obtained. Methods: Thirty-eight older adults (age range: 66–97 years old) with a visual impairment (acuity <20/70) were recruited before the onset of their low vision rehabilitation. The second objective was to examine which of these correlations would remain significant once established variables that influence cognition are statistically removed (e.g., age, education). We hypothesized that more severe impairment of visual acuity and contrast sensitivity would be correlated with more advanced levels of cognitive impairment. Objectives and hypothesis: The aim of this pilot study was to assess correlations between visual and cognitive functions in older adults referred for low vision rehabilitation. Low vision rehabilitation could possibly be a protective factor against cognitive decline, as it provides the clients with compensatory strategies to overcome their visual deficits. Research indicates that vision and hearing loss is correlated with age-related cognitive decline, and with a higher risk of developing dementia due to Alzheimer’s disease. However, some of these changes can become pathological. Introduction: The occurrence of age-related vision changes is inevitable. 4School of Physical and Occupational Therapy, McGill University, Montréal, QC, Canada.3Department of Psychology, Université de Montréal, Montréal, QC, Canada.2Department of Psychology, Concordia University, Montréal, QC, Canada.1School of Optometry, Université de Montréal, Montréal, QC, Canada.Demographic factors must be considered when interpreting this measure.Gabrielle Aubin 1, Natalie Phillips 2, Atul Jaiswal 1, Aaron Paul Johnson 2, Sven Joubert 3, Vanessa Bachir 1, Eva Kehayia 4 and Walter Wittich 1,2,4 * These findings highlight the need for population-based norms for the MoCA and use of caution when applying established cut scores, particularly given the high failure rate on certain items. Normative data stratified by age and education were derived.

Most frequently missed items included the cube drawing (59%), delayed free recall (56% <4/5 words), sentence repetition (55%), placement of clock hands (43%), abstraction items (40%), and verbal fluency (38% <11 words in 1 minute). Total scores were lower than previously published normative data (mean 23.4, SD 4.0), with 66% falling below the suggested cutoff (<26) for impairment. Frequency of missed items was also reviewed. Pearson correlations and analysis of variance were used to examine relationship to demographic variables. Normative data were generated by age and education. The MoCA was administered to 2,653 ethnically diverse subjects as part of a population-based study of cardiovascular disease (mean age 50.30 years, range 18-85 Caucasian 34%, African American 52%, Hispanic 11%, other 2%). To provide normative and descriptive data for the Montreal Cognitive Assessment (MoCA) in a large, ethnically diverse sample.
