The aim of this work is to narratively review findings on emotional and social adjustment among visually impaired older adults. The definition of emotional adjustment employed here includes a decline in mental health, especially the occurrence of depression, as well as less severe manifestations of emotional disturbance, such as lower well-being. Empirical research on these topics strongly and consistently confirms difficulties in emotional functioning among visually impaired elders. In particular, a considerable body of research using different methodologies has shown the prevalence of depression in visually impaired groups to be at least twice as high as that found in normal populations. Social adjustment to vision loss is construed to involve difficulties in social functioning, changes in social support, and loneliness. Although research findings indicate loss of social activity and, to a lesser extent, loss of social support among the visually impaired, the relationship between vision loss and loneliness remains unclear. There are, however, firm indications that social support can provide an effective buffer against age-related vision loss.
There is a need for society to develop counseling systems to meet very old people's ambivalence and practical considerations to move or not to move. Thus, the ambivalence to stay put or to relocate needs to be further explored from an applied perspective by also taking nonmovers into account.
Objectives Hearing, vision, and cognitive impairment commonly co‐occur in older adults. Improving sensory function may positively impact outcomes in people with dementia (PwD). We developed a “sensory intervention” (SI) to support hearing and vision in PwD. Here, we report the findings of an international open‐label field trial, and nested case series, to explore the impact of the SI on dementia‐related outcomes. Methods This was a home‐based trial conducted in France, England, and Cyprus. Participants were people with mild‐to‐moderate dementia and hearing and/or vision impairment (n = 19) and their study partners (unpaid carers; n = 19). The “basic” SI included a hearing and vision assessment and provision of glasses and/or hearing aids. A subsample received the “extended” SI with additional weekly visits from a sensory support therapist (SST). Exploratory analyses of dementia‐related, health utility and resource utilisation outcomes were performed. Results Quality of life (QoL) and sensory functional ability improved. Change in QoL exceeded the threshold for a minimum clinically important difference. There was a modest improvement (in absolute terms) post intervention in behavioural disturbance, self‐efficacy, and relationship satisfaction. Study partner time assisting instrumental activities of daily living (iADL) and supervision decreased by about 22 and 38 hours per month, respectively, although time for personal ADL support increased. Qualitative data supported effectiveness of the intervention: PwD were more socially engaged, less isolated, less dependent on study partners, and had improved functional ability and communication. Conclusions These findings support the need for a definitive randomised controlled trial (RCT) to evaluate the effectiveness of the intervention.
Background:Age-related hearing and vision problems are common among people with dementia and are associated with poorer function, reduced quality of life and increased caregiver burden. Addressing sensory impairments may offer an opportunity to improve various aspects of life for people with dementia.Methods:Electronic databases were searched using key terms dementia, hearing impairment, vision impairment, intervention, and management. Database searches were supplemented by hand searching bibliographies of papers and via consultation with a network of health professional experts. Studies were eligible for inclusion if they included adults aged over 50 with dementia with adult-onset hearing or vision impairment who had received a hearing or vision intervention in relation to cognitive function, rate of decline, psychiatric symptoms, hearing/vision-related disability, quality of life, and/or caregiver burden outcomes. A range of study designs were included. Results were summarized descriptively according to level of evidence and effect sizes calculated where possible. Risk of bias was assessed using Downs and Black's (1998) checklist. The development of the intervention was summarized according to the CReDECI2 scheme. PROSPERO review registration number 2016:CRD42016039737.Results:Twelve papers describing hearing interventions and five papers describing vision interventions were included. Most were of low to moderate quality. One high quality randomized controlled trial of a hearing aid intervention was identified. Hearing interventions included provision of hearing aids, assistive listening devices, communication strategies, hearing aid trouble shooting, and cochlear implantation. Vision interventions included prism lenses, rehabilitation training, and cataract surgery. There was no consistent evidence for the positive impact of hearing/vision interventions on cognitive function, rate of cognitive decline, quality of life, or caregiver burden.Conclusion:Sensory interventions may promote better outcomes, but there is a need for properly powered, controlled trials of hearing and vision interventions on outcomes relevant to people living with dementia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
