Using co-creation focus groups to customise a remote multidomain programme designed to increase dementia literacy.

OBJECTIVES: To adapt the content and functionalities of Brain Health PRO, a web-based multidomain program designed to increase dementia literacy, to the context and needs of users, providers and community organisations across Québec, Canada. DESIGN: Five consecutive qualitative co-creation focus group sessions 30-90 min in duration each, exploring potential barriers and facilitators to usability, accessibility, comprehensibility, participant recruitment and retention. SETTING: Virtual meetings. PARTICIPANTS: A 15-member team based in Québec and Ontario, Canada, consisting of 9 researchers (including a graduate student and the project coordinator), representing occupational therapy, sensory rehabilitation, neuropsychology, psychology, health science and research methods, 3 informal caregivers of older adults living with cognitive decline and 3 members of the Federation of Quebec Alzheimer Societies. DATA ANALYSIS: Session recordings were summarised through both qualitative description and thematic analysis. RESULTS: The synthesised recommendations included adjustments around diversity, the complexity and presentation styles of the materials, suggestions on refining the web interface and the measurement approaches; it influenced aspects of participant recruitment, retention efforts and engagement with the content of Brain Health PRO. CONCLUSIONS: Co-creation in dementia prevention research is important because it involves collaboration between researchers, community support and service providers, and persons with lived experience as care providers, in the design and implementation of clinical studies. This approach helps to ensure that the content and presentation of educational material is relevant and meaningful to the target population and those involved in its delivery, and it leads to a greater understanding of their needs and perspectives.

Visual and cognitive functioning among older adults with low vision before vision rehabilitation: A pilot study.

Introduction: The occurrence of age-related vision changes is inevitable. However, some of these changes can become pathological. 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. 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. 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. We hypothesized that more severe impairment of visual acuity and contrast sensitivity would be correlated with more advanced levels of cognitive impairment. 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). 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. 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. 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. Correlations between contrast sensitivity and memory, as well as between global cognition and visual aid use remained significant after controlling for age and education. 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.

Usability and Accessibility of the ArtontheBrain™ Virtual Recreation Activity for Older Adults With Low Vision Due to Age-Related Macular Degeneration.

Experiencing visual art can inspire, be an overall positive leisure activity, and has been linked to improved cognition, especially in older adults. Access to artwork in a museum environment can comprise a variety of barriers, including difficulties linked to its visual experience for persons that are visually impaired. The present study explored the barriers and facilitators experienced by 15 older adults (age 65 to 93) living with age-related macular degeneration when using an iPad to access ArtontheBrain™, a virtual art museum recreation experience created by members of this team. Using the Concurrent Think Aloud method, participants were asked to continuously comment on their experiences with the application while being audio/video recorded. Indeed, codes were determined by identifying frequently stated and emphasized ideas or behaviors of participants using the ArtontheBrain™ application. Transcripts underwent thematic analysis and indicated that the main access barriers were linked to control of the contrast, magnification, and the tactile interface on the tablet device. The learn and play activities as well as the text-to-speech feature were identified as facilitators for ArtontheBrain™ engagement. The present findings should also be considered in the larger context of application development, as this study provides insight pertaining to the needs of low vision individuals regarding usability and accessibility.

Use of three-dimensional printing as a rehabilitation tool for individuals with deafblindness or vision impairment: a scoping review protocol.

OBJECTIVE: This scoping review aims to synthesize evidence on the practices involving additive manufacturing, also known as three-dimensional printing, as a rehabilitation tool to assist individuals with deafblindness or vision impairment, and to identify which International Classification of Functioning, Disability and Health domains of functioning can be improved by its use. The goal is to inform health care professionals and family caregivers on how additive manufacturing may enhance the quality of life of people with deafblindness or vision impairment. INTRODUCTION: Deafblindness and vision impairment impact many life domains, such as access to information, communication, and mobility. The sense of touch is the main gateway for communication for individuals living with these impairments. Additive manufacturing is a promising technology for producing customized, tactile-based, low-cost tangible objects and devices that could improve the functioning of those with sensory impairment. Emerging studies explore the benefits of additive manufacturing in rehabilitation, education, and inclusion of people living with vision impairment, but very little is known about its use for the deafblind. INCLUSION CRITERIA: This review will consider studies that focus on the most widespread additive manufacturing technologies for the use of individuals living with deafblindness or vision impairment, their family caregivers, or professionals who provide their rehabilitation care. METHODS: A comprehensive search of 10 databases (PsycINFO, MEDLINE, Global Health, PubMed, CINAHL, Embase, ERIC, Web of Science, Engineering Village, and Scopus) will be conducted. Screening of records will be done at the title/abstract level and at the full-text level by independent reviewers of the team.

Cognitive Impairment in Older Adults With Concurrent Hearing and Vision Impairment: A Systematic Scoping Review Protocol.

Introduction: As the prevalence of age-related sensory impairment increases, more evidence emerges on the association between uni-sensory and cognitive impairment (CI) in older adults. However, the link between CI and concurrent hearing and vision impairment (referred to as dual sensory impairment/DSI) is not well-understood, and this combined effect may be additive or multiplicative. Moreover, the existing evidence on CI in older adults with DSI is scattered and limited. Through this systematic scoping review, we aim to map existing evidence on CI in older adults with DSI, and to summarize what is known about the prevalence, incidence and risk factors of CI, and tools used to screen or assess CI in older adults with DSI. Methods and Analysis: We will use the Joanna Briggs Institute framework to perform the review. Eleven databases [MEDLINE, CINAHL/EBSCO, EMBASE, Mednar, WorldWideScience, PsycEXTRA, OAIster, OpenGrey (SIGLE), Global Health, PsycINFO, and Web of Science] and clinical trial registries (ISRCTN Registry, WHO ICTRP, and ClinicalTrials.gov) will be searched. Study selection will be completed using Covidence, and data will be extracted using an a priori data extraction tool. To be included, studies had to be peer-reviewed, had older adults with DSI as the focal population, and are related to CI. Data will be presented using a narrative summary with emphasis on implications for future research and practice. Discussion: Reliable cognitive screening is of the utmost importance for prevention and treatment of CI within DSI population. The study findings will have significant implications for health services delivery and policy research. The summarized findings on the prevalence, incidence, associated risk factors, and CI screening and assessment tools will inform geriatric care. The review will also document knowledge gaps on CI in the DSI population and identify areas of interest for future studies. Ethics and Dissemination: The scoping study, being a review of existing documents, does not require ethics approval. The findings will be disseminated with relevant stakeholders using knowledge translation activities such as scientific presentations and publications. We intend to use the findings to conduct a Delphi study to evaluate which CI tools are suitable for older population with DSI.

Effect of Reading Rehabilitation for Age-Related Macular Degeneration on Cognitive Functioning: Protocol for a Nonrandomized Pre-Post Intervention Study.

BACKGROUND: Age-related vision impairments and dementia both become more prevalent with increasing age. Research into the mechanisms of these conditions has proposed that some of their causes (eg, macular degeneration/glaucoma and Alzheimer's disease) could be symptoms of an underlying common cause. Research into sensory-cognitive aging has provided data that sensory decline may be linked to the progression of dementia through reduced sensory stimulation. While hearing loss rehabilitation may have a beneficial effect on cognitive functioning, there are no data available on whether low vision rehabilitation, specifically for reading, could have a beneficial effect on cognitive health. OBJECTIVE: The research questions are: (1) Does low vision rehabilitation reduce reading effort? (2) If so, does reduced reading effort increase reading activity, and (3) If so, does increased reading activity improve cognitive functioning? The primary objective is to evaluate cognition before, as well as at 6 months and 12 months after, 3 weeks of low vision reading rehabilitation using magnification in individuals with age-related macular degeneration, with or without coexisting hearing impairments. We hypothesize that improvements postrehab will be observed at 6 months and maintained at 12 months for participants with vision loss and less so for those with dual sensory loss. The secondary objective is to correlate participant characteristics with all cognitive outcomes to identify which may play an important role in reading rehabilitation. METHODS: We employ a quasiexperimental approach (nonrandomized, pre-post intervention study). A 3x3 design (3 groups x 3 time points) allows us to examine whether cognitive performance will change before and after 6 months and 12 months of a low vision reading intervention, when comparing 75 low vision and 75 dual sensory impaired (vision & hearing) participants to 75 age-matched healthy controls. The study includes outcome measures of vision (eg, reading acuity and speed), cognition (eg, short-term and long-term memory, processing speed), participant descriptors, demographics, and clinical data (eg, speech perception in noise, mental health). RESULTS: The study has received approval, and recruitment began on April 24, 2019. As of March 4, 2021, 38 low vision and 7 control participants have been enrolled. Lockdown forced a pause in recruitment, which will recommence once the COVID-19 crisis has reached a point where face-to-face data collection with older adults becomes feasible again. CONCLUSIONS: Evidence of protective effects caused by reading rehabilitation will have a considerable impact on the vision rehabilitation community and their clients as well as all professionals involved in the care of older adults with or without dementia. If we demonstrate that reading rehabilitation has a beneficial effect on cognition, the demand for rehabilitation services will increase, potentially preventing cognitive decline across groups of older adults at risk of developing macular degeneration.
