Promoting functional independence in people with Alzheimer's disease: Outcomes of a home-based occupational therapy intervention in Spain

Real-world occupational therapy interventions for early-stage dementia: Characteristics and contextual barriers

AimThere is an absence of evidence generated in a UK context to support interventions based on occupational therapists' core skills for people living with early-stage dementia. To inform the development of a programme theory and a future evaluation, this paper aimed to describe real-world (routine) community-based occupational therapy interventions for this population and contextual barriers.MethodOccupational therapy practitioners (n = 21) from five Health Boards in Wales, UK participated in semi-structured interviews (n = 17) which were audio recorded, transcribed, and analysed thematically.FindingsThe availability of, and access to, real-world community-based interventions was variable, and associated with multilevel contextual barriers (resources, understanding of dementia specialist occupational therapy, professional influence, and evidence base). Where available and accessible, contents comprised a pre-intervention component (relational work, assessment, and goal setting) and intervention component (personalised problem-solving and coping strategies, emotional support, and advice and signposting), to meet needs associated with everyday activities and poor wellbeing. Variation in mode, duration, contents, and who received interventions, was associated with contextual barriers.ConclusionFindings indicate that the development of an intervention programme theory and future evaluation design, will need to account for the impact context may have on the variability of real-world intervention characteristics, and how this in turn may influence outcomes.

Implementing reablement for community dwelling people with dementia: A formative evaluation using single-case experimental design

BACKGROUND

Reablement is recommended to maximise functioning in people with dementia, yet in Australia, is not routinely available. This study aimed to provide insight into the implementation and program outcomes of reablement in real-world practice for a person living with dementia.

METHODS

Reablement was implemented for a client with dementia. In parallel, a formative mixed-methods pilot evaluation was performed, using single-case experimental A-B-A design (n = 1), supplemented by routinely collected pre-post program clinical measures. Implementation was evaluated qualitatively via clinical notes for fidelity, feasibility and client engagement.

RESULTS

Single-case experimental design outcomes indicated the program positively impacted the participant's physical functioning. Additionally, most routinely collected pre-post clinical measures demonstrated improvement. Intervention fidelity varied, with differences in length and client engagement.

CONCLUSION

Implementation of evidence-informed reablement has been shown to be feasible in real-world practice for a community-dwelling person living with dementia. Larger implementation trials are needed to build on preliminary outcomes to ultimately improve access to these important programs.

Quality-of-Life- and Cognitive-Oriented Rehabilitation Program through NeuronUP in Older People with Alzheimer's Disease: A Randomized Clinical Trial

(1) Background: Alzheimer's disease (AD) is a progressive neurodegenerative disorder marked by cognitive decline and functional impairment. The NeuronUP platform is a computer program whose main function is cognitive stimulation through three types of activities that change so that the user does not manage to learn it. This program provides opportunities to work on various domains, including activities of daily living (ADLs), social skills, and cognitive functions. The main objective of this randomized clinical trial was to assess the impact of integrating the NeuronUP platform with conventional occupational therapy to enhance or maintain cognitive, perceptual, and quality of life (QoL) abilities in people with AD compared to a control group. (2) Methods: A randomized, single-blind clinical trial was conducted. The sample was randomized using a software program, OxMar, which allowed the separation of the sample into a control group (CG) that received their conventional occupational therapy sessions and an experimental group (EG) that received therapy with NeuronUP, in addition to their conventional occupational therapy sessions. An eighteen-week intervention was conducted. (3) Results: The study included 20 participants, and significant differences were observed in most variables analyzed, indicating improvements after the intervention, particularly in measures of QoL and cognitive status. (4) Conclusions: Our findings demonstrate that an eighteen-week experimental protocol, incorporating the NeuronUP platform alongside conventional occupational therapy, led to improvements in cognitive status and QoL in older adults with AD. Thus, integrating the NeuronUP platform as a complementary tool to occupational therapy can be a valuable resource for enhancing the QoL of individuals with AD. However, due to the small sample size, further studies are needed to corroborate these findings.

Photobiomodulation's potential as a non-invasive therapy for alzheimer's disease and minimal cognitive impairment: A 12-week investigation

BACKGROUND

Alzheimer's Disease (AD), undergoing a faster increase in occurrence than any other type of dementia, lacks a curative remedy despite advanced discoveries. To explore the realm of non-pharmacologic therapies, our study evaluates the 12-week impact of non-invasive Photobiomodulation (PBM) on cognitive and psychological aspects in individuals with AD and minimal cognitive impairment (MCI). The urgency of exploring innovative interventions is underscored by the rising occurrence of AD, particularly in regions with aging populations like Iran.

METHOD

13 patients (6 case patients and 7 control patients) participated in the study. Sham treatment was administered to seven individuals, while another six received PBM treatment over 12 weeks, with daily at-home LED (810 nm wavelength) device usage lasting 20 min. Initially, the patient and their caregiver participated in two hospital sessions to acquaint them with the device's operation.

RESULTS

The mean reduction of Hamilton's anxiety questionnaire score was 3.33±6.08 in the intervention group and 2.00±3.46 in the control group (p-value=0.836). The mean score reduction of the Hamilton depression questionnaire was 3.16±3.86 in the intervention group and 4.85±6.20 in the control group (p-value=0.836). The mean score of the DAD questionnaire in the intervention group before the study was 25.50±13.13 and after the intervention was 29.83±12.12 (p-value=0.084) and in the control group it was 29.71±8.19 and after the study was 29±0.972 (p-value = 0.526). The mean changes in the DAD questionnaire score in the intervention group increased by 4.33±4.92 and decreased by 0.71±2.81 in the control group (p-value=0.041).

CONCLUSION

In general, PBM appears to hold promise as a potentially safe method for enhancing the cognitive, functional, and psychological status of individuals with Alzheimer's disease, though further research with larger sample size and cautious interpretation are warranted.

Occupational Therapy Interventions for Persons with Cognitive Impairments Living in the Community

This study describes interventions provided by community occupational therapists for persons with cognitive impairments. Using an online questionnaire, a cross-sectional study was conducted, collecting data from 497 of the 1367 occupational therapists in Norwegian community-based services. The most common interventions provided were environmental modifications (87%), implementation of assistive devices (85%), and training of activities of daily life (ADL) (77%). Two main reasons to carry out these interventions were identified as the initial assessment of clients (89%) and expectations of others. The most preferred interventions were ADL training (77%), cognitive training (63%), and environmental modifications (56%). Chi-squared tests identified a significant difference (p < 0.001) between interventions provided and preferred interventions on all interventions except environmental modifications. The findings provide an insight into interventions provided for persons with cognitive impairments in community services.

Predictors of resilience for people with spinal cord injury over two periods of COVID-19 social distancing restrictions: a 12-month longitudinal study using structural equation modelling

BACKGROUND

The novel coronavirus (COVID-19) pandemic is disproportionately impacting the health of people with disability. Resilience has remained an important health promoting characteristic during periods of social distancing restrictions. Factors promoting resilience for people with disability under the context of the pandemic remains poorly understood. Studies have yet to investigate evidence-based factors that promote resilience over multiple periods of restrictions for people with disability.

METHODS

A longitudinal study developed via a collaborative partnership between peer-support workers with lived experience of spinal cord injury (SCI) and university researchers was undertaken to fill knowledge gaps around factors promoting resilience for people with SCI during two periods of stringent social distancing restrictions within Victoria, Australia. Over 12-months, participants with SCI completed two surveys, towards the end of two lockdown periods. Evidence-based factors associated with resilience were measured. The Impact on Participation and Autonomy Questionnaire, the International SCI Quality of Life scale, and the 10-item Conor Davidson Resilience Scale, respectively measured autonomy and participation limitations, life satisfaction and psychological health, and resilience. A structural equation modelling (SEM) approach established factors directly and indirectly associated with resilience.

RESULTS

A model with excellent fit was produced. During two extended lockdowns over the 12-month period, increased family role limitations and favourable psychological health were respectively, negatively (Lockdown 1 [n = 127]: β = -.251, p < .01, Lockdown 2: β = -.400, p < .01) and positively (Lockdown 1: β = .601, p < .01, Lockdown 2 [n = 65]: β = .430, p < .01) associated with resilience. Indirect negative associations between resilience and increased outdoor autonomy limitations (Lockdown 1: β = -.195, p < .01, Lockdown 2: β = -.255, p < .01) and social life limitations (Lockdown 1: β = -.217, p < .01, Lockdown 2: β = -.142, p < .05) existed, and these relationships were moderated by psychological health.

CONCLUSIONS

Psychological health, and participation and autonomy are determinants of resilience during periods of crisis. Health and social care providers and public health departments should prioritise programs promoting these domains, to counter the negative impact of social distancing.

Cognitive stimulation and activities of daily living for individuals with mild-to-moderate dementia: A scoping review

Introduction:

Dementia is a progressive syndrome that interferes with the individual’s ability to perform activities of daily living (ADL). Cognitive stimulation (CS) is a non-pharmacological approach aimed to mitigate the impact of dementia symptoms. While CS has been shown to provide benefits for cognition and quality of life, the evidence supporting its use in improving ADL outcomes is reduced. The aim of this review was to chart what is known from the literature about the use of CS in improving ADL outcomes.

Method:

A scoping review of the use of CS in improving ADL outcomes for individuals with mild-to-moderate dementia was conducted, following a scoping review methodological framework. Eight databases were searched, including all articles published up until June 2022.

Findings:

A three-step search strategy yielded 788 results. Following screening and review, 36 papers met the inclusion criteria for this review. Studies were charted and discussed in the areas of (1) cognitive stimulation therapy; (2) group CS programmes; (3) multi-component CS interventions; (4) individual CS programmes and (5) other types of CS.

Conclusion:

The review identified a range of CS programmes from across 13 countries worldwide. Multi-component CS interventions involving ADL-focused activities reported the most benefits for ADL outcomes.

Home-Based Occupational Therapy for Adults With Dementia and Their Informal Caregivers: A Systematic Review

IMPORTANCE

People with dementia require tailored interventions to support participation and performance in their desired occupations, and informal caregivers need interventions that reduce caregiving burden to enable them to continue with their roles.

OBJECTIVE

This systematic review investigated whether home-based occupational therapy interventions for adults with dementia and their informal caregivers optimized care recipients' performance of daily occupations and reduced caregiving burden and improved caregivers' sense of competence.

DATA SOURCES

Eight databases were searched from 1946 to November 2019 using MeSH terms, keywords, and subject headings as appropriate for each database. Inclusion criteria were quantitative studies investigating the effects of home-based therapy provided by a qualified occupational therapist for adults with dementia and their informal caregivers.

STUDY SELECTION AND DATA COLLECTION

Study selection, data collection, and methodological quality assessments using the Critical Appraisal Skills Programme criteria tool were performed independently by two reviewers. Data analysis involved a two-stage process.

FINDINGS

From 1,229 articles identified through searches, 970 titles and abstracts were screened for eligibility after removal of duplicates. Twenty studies reported in 22 articles were included. Moderate evidence supported interventions provided jointly for adults with dementia and their informal caregivers using a combination of intervention strategies. Included studies demonstrated high risk of bias, particularly in blinding of outcome assessments.

CONCLUSIONS AND RELEVANCE

Combining individualized interventions framed in client-centeredness can enhance occupational performance for adults with dementia, reduce caregiving burden, and improve informal caregivers' sense of competence. Further research on leisure and home management occupations is warranted.

WHAT THIS ARTICLE ADDS

The findings provide evidence supporting the effectiveness of home-based occupational therapy for people with dementia and their informal caregivers for consideration by funders of services.

Therapeutic Potential of Photobiomodulation In Alzheimer's Disease: A Systematic Review

Introduction: Alzheimer disease (AD) is characterized by the decline of cognitive functions such as learning and memory. Scientific society has proposed some non-pharmacological interventions, among which photobiomodulation has gained prominence for its beneficial effects. Therefore, we investigated, through systematic review, the therapeutic potential of photobiomodulation in AD. Methods: This systematic review was registered under the number CRD42019128416 in the International Prospective Record of Systematic Reviews (PROSPERO). A systematic search was conducted on the bibliographic databases (PubMed and ScienceDirect) with the keywords based on MeSH terms: "photobiomodulation therapy" or "low-level laser therapy" or "LLLT" or "light emitting diode" and "amyloid" or "Alzheimer". The data search was conducted from 2008 to 2019. We follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The search strategy included experimental in vivo and in vitro studies in the English language and photobiomodulation as a non-pharmacological intervention. We included 10 studies, being 5 in vivo studies, 4 in vitro studies and 1 study using in vivo and in vitro. To evaluate the quality of the studies, we used the Rob tool of the Systematic Review Center for Laboratory Animal Experimentation (SYRLE). Results: The studies showed that photobiomodulation is able to reduce inflammatory response, oxidative stress and apoptotic effects generated by amyloid beta (Aβ) and restore mitochondrial function and cognitive behavior. Conclusion: Taken together, these results indicate that photobiomodulation may be a useful tool for treating AD.
