A scoping review: Sensory interventions for older adults living with dementia

An Auditory Sonic Sleep Treatment for Individuals Living With Dementia in a Memory Care Setting: A Quality Improvement Program Evaluation

BACKGROUND

The absence of a cure for dementia, combined with the increased longevity of the baby boom generation, is resulting in a dramatic increase in the number of people living with dementia. Aging-related changes coupled with dementia-related behavioral symptoms pose unique challenges for those living with dementia as well as those who provide care. There is evidence that improved sleep can improve health and well-being. Research also supports using auditory interventions as a form of nonpharmacological therapy.

OBJECTIVE

This study evaluated the effects of a customized auditory (sonic) treatment during sleep on the mood, behavior, quality of life, functional ability, and health condition of individuals living with the symptoms of dementia. Workforce outcomes were evaluated as a secondary outcome.

METHODS

A controlled before-after design with a mixed-method approach was used to evaluate the impact of the sonic sleep treatment during baseline, intervention, and discontinuation time frames.

RESULTS

Statistically significant improvements were observed in participants' cooperation with care (p = .0249) and daytime drowsiness (p = .0104). Other nonstatistically significant improvements included bed mobility, appetite, bathing self-performance, toilet use, incidence of falls, following requests and instructions, and nighttime insomnia. While workforce outcomes remained unchanged, staff were supportive of resuming the sonic sleep treatment after the discontinuation time frame.

CONCLUSIONS

The sonic sleep treatment demonstrated improved outcomes for individuals living with dementia. This supports using an appropriate auditory stimulus as a fundamental component of care for individuals living in memory care settings.

Homing wellness: can narrative design transform living spaces for people with dementia into engaging environments enabling communication?

Interactive design is an emerging trend in dementia care environments. This article describes a research project aiming at the design and development of novel spatial objects with narrative attributes that incorporate embedded technology and textiles to support the wellbeing of people living with dementia. In collaboration with people with dementia, this interdisciplinary research project focuses on the question of how innovative spatial objects can be incorporated into dementia long-term care settings, transforming the space into a comforting and playful narrative environment that can enhance self-esteem while also facilitating communication between people living with dementia, family, and staff members. The research methodologies applied are qualitative, including Action Research. Participatory design methods with the experts by experience-the people with dementia-and health professionals have been used to inform the study. Early findings from this research are presented as design solutions comprising a series of spatial object prototypes with embedded technology and textiles. The prototypes were evaluated primarily by researchers, health professionals, academics, and design practitioners in terms of functionality, aesthetics, and their potential to stimulate engagement. The research is ongoing, and the aim is to evaluate the prototypes by using ethnographic and sensory ethnography methods and, consequently, further develop them through co-design workshops with people living with dementia.

Disabled People or Their Support Persons' Perceptions of a Community Based Multi-Sensory Environment (MSE): A Mixed-Method Study

Multi-sensory environments (MSEs) are specialised spaces purposely designed to stimulate the senses, whilst providing a calming and relaxing environment for leisure and enjoyment, predominantly intended for disabled people. Most MSEs are in institutions, hospitals, or educational settings, with a few in community-based settings. We explored disabled users' experiences of a community based MSE in a large metropolitan area in New Zealand, with a view to expanding access to MSE-type environments within the area. We used a convergent mixed method design with a web-based electronic survey (e-survey; n = 105), as well as semi-structured interviews (n = 14) with disabled MSE users (adults and children), who were supported, where necessary, by their support person/s. We collected the MSE users' demographics, frequency of use with respect to age, disability, and ethnicity, and experiences of the room, equipment, and accessibility. The participants and their support persons' perspectives about their experiences of using the MSE were represented by four themes: (i) Self-determination; (ii) Enhancing wellbeing opportunities; (iii) the MSE itself; (iv) Accessibility. While the MSE was considered positively, the MSE experience could be enhanced by addressing access challenges and broadening the scope of equipment to improve the usability and make it a more inclusive environment for all.
