“…For instance, individuals suffering from AD have difficulties in color and depth perception [11], visuospatial organization [12], control of visual attention [13] and in visual search tasks with simple stimuli [14]. These low-level visual deficits occur independently of memory problems in AD [15] and may result from the concentration of neuropathology in the visual cortex [16].…”

Short title (running head): face inversion effect in Alzheimer's disease © 2 AbstractPrevalent face recognition difficulties in Alzheimer disease have typically been attributed to the underlying episodic and semantic memory impairment. The aim of the current study was to determine if AD patients are also impaired at the perceptual level for faces, more specifically at extracting a visual representation of an individual face. To address this question, we investigated the matching of simultaneously presented individual faces and of other nonface familiar shapes (cars), at both upright and inverted orientation, in a group of mild AD patients and in a group of healthy older controls matched for age and education. AD patients showed a reduced inversion effect (i.e. larger performance for upright than inverted stimuli) for faces, but not for cars, both in terms of error rates and response times. While healthy participants showed a much larger decrease in performance for faces than for cars with inversion, the inversion effect did not differ significantly for faces and cars in AD. This abnormal inversion effect for faces was observed in a large subset of individual patients with AD. These results suggest that AD patients have deficits in higher-level visual processes, more specifically at perceiving individual faces, a function that relies on holistic representations specific to upright face stimuli. These deficits, combined with their memory impairment, may contribute to the difficulties in recognizing familiar people that are often reported in patients suffering from the disease and by their caregivers.3

“…In another study, significantly better MMSE scores were obtained three months posthearing aid fitting compared to prefitting unaided scores (Acar, Yurekli, Babademez, Karabulut, & Karasen, 2011). Likewise, customizing the visual displays used in cognitive testing has been shown to reduce apparent cognitive declines in patients with AD and to eliminate them in healthy older adults and patients with Parkinson's disease (Toner et al, 2012). Thus, cognitive test results may be improved if care is taken to ensure that older adults have the best possible access to auditory and/or visual test stimuli given their sensory functioning and needs.…”

Many standardized measures of cognition include items that must be seen or heard. Nevertheless, it is not uncommon to overlook the possible effects of sensory impairment(s) on test scores. In the current study, we investigated whether sensory impairments could affect performance on a widely used screening tool, the Montreal Cognitive Assessment (MoCA). Three hundred and one older adults (mean age = 71 years) completed the MoCA and also hearing and vision tests. Half of the participants had normal hearing and vision, 38% impaired hearing, 5% impaired vision, and 7% had dual-sensory impairment. More participants with normal sensory acuity passed the MoCA compared to those with sensory loss, even after modifying scores to adjust for sensory factors. The results suggest that cognitive abilities may be underestimated if sensory problems are not considered and that people with sensory loss are at greater risk of cognitive decline.

Introduction: We created a summary score for multiple sensory (multisensory) impairment and evaluated its association with dementia. Methods: We studied 1794 adults aged 70 to 79 who were dementia-free at enrollment and followed for up to 10 years in the Health, Aging, and Body Composition Study. The multisensory function score (0 to 12 points) was based on sample quartiles of objectively measured vision, hearing, smell, and touch summed overall. Risk of incident dementia and cognitive decline (measured by two cognitive tests) associated with the score were assessed in regression models adjusting for demographics and health conditions. Results: Dementia risk was 2.05 times higher (95% confidence interval [CI] 1.50-2.81) comparing "poor" to "good" multisensory score tertiles and 1.45 times higher comparing the "middle" to "good" tertiles (95% CI 1.09-1.91). Each point worse in the multisensory function score was associated with faster rates of cognitive decline (P < .05). Conclusions: Worsening multisensory function, even at mild levels, was associated with accelerated cognitive aging.
