Sonas: a pilot study investigating the effectiveness of an intervention for people with moderate to severe dementia

Effectiveness of nonpharmacological multi-component intervention on depressive symptoms in patients with mild cognitive impairment and dementia: A systematic review and meta-analysis

Patients with mild cognitive impairment (MCI) and dementia are more prone to depression than people without MCI or dementia. Some studies have found nonpharmacological multi-component intervention to be more effective than single-component intervention in improving the condition of patients with MCI and dementia; however, their effect on depressive symptoms is still inconsistent. Therefore, it is necessary to explore the effectiveness of nonpharmacological multi-component intervention in improving depressive symptoms in patients with MCI and dementia. This review retrieved papers from PubMed, Embase, Cochrane Library, CINAHL, PsycINFO and CNKI. The retrieval time limit was set from 1 January 1990 to 25 November 2022. The PRISMA 2020 guideline was used to report the included studies. The result showed that nonpharmacological multi-component intervention could improve depressive symptoms in patients with MCI and dementia. Among them, nonpharmacological multi-component intervention with a duration of <6 months, physical and cognitive activities, or other activities had significant effects. However, each study differed in terms of specific measures, duration and frequency of intervention methods. Accordingly, more randomized controlled trials with larger samples are required to discover the best scheme for nonpharmacological multi-component intervention.

Effects of multisensory environment/stimulation therapy on adults with cognitive impairment and/or special needs: A systematic review and meta-analysis

AIM

This review aimed to evaluate the effects of multisensory environments/stimulation (MSE/MSS) therapy, on the behavior and psychological symptoms in adults with cognitive impairment and/or special needs.

METHODS

Online database searches were performed to identify studies reporting on the effects of MSS/MSE therapy in adults (>18 years). Data were extracted for the following investigated outcomes including anxiety, depression, mood, behavioral attributes, biomedical parameters, cognition, motor skills, quality of life (QoL), pain, and end of life quality. Two reciprocally blinded investigators extracted the data. Inter-investigator reliability (𝝹) was calculated. A meta-analysis and a qualitative analysis were performed on the information extracted.

RESULTS

Thirty-six studies were included for data extraction and analysis. Meta-analysis of the included studies revealed a significant improvement with the MSE/MSS therapy, for agitation (p = .018), anxiety (p = .023), cognition (p < .001), and depression (p < .001). MSS/MSE therapy demonstrated a tendency for the improvement of the QoL in adults (p = .05).

CONCLUSION

MSE/MSS therapies are beneficial in cognitively impaired adults and improve their anxiety, depression, cognitive and other behavioral attributes such as agitative behaviors. Promoting these therapies in geriatric care may help to improve/reduce the challenging/care-resistant behaviors in adults and facilitate effective provision of the necessary care.

Effectiveness of treatments for people living with severe dementia: A systematic review and meta-analysis of randomised controlled clinical trials

BACKGROUND

Dementia is a progressive neurodegenerative syndrome that has no cure. Although a significant proportion of people with dementia progress into the severe stages of the disease, evidence on the clinical effectiveness of treatments for people with severe dementia remains limited.

AIMS

To systematically review the effectiveness of pharmacological and non-pharmacological treatments for people living with severe dementia and assess the quality of the evidence.

METHOD

We searched MEDLINE, EMBASE, PsycINFO, CINAHL and online clinical trial registers up to January 2022, for Randomised Controlled Trials (RCT) in people living with severe dementia. Quality and risk of bias were assessed independently by two authors.

RESULTS

A total of 30 trials met our inclusion criteria of which 14 evaluated the effectiveness of pharmacological treatments, and 16 evaluated a non-pharmacological intervention. Pharmacological treatments: Meta-analyses indicated that pharmacological treatments (donepezil: 10 mg, 5 mg; galantamine: 24 mg; memantine: 10 mg) are associated with better outcomes compared to placebo for: severity of symptoms (standardized mean difference (SMD) 0.37, 95% CI 0.26-0.48; 4 studies; moderate-certainty evidence), activities of daily living (SMD 0.15, 95% CI 0.04-0.26; 5 studies; moderate-certainty evidence), and clinical impression of change (Relative Risk (RR) 1.34, 95% CI 1.14-1.57; 4 studies; low-certainty evidence). Pharmacological treatments were also more likely to reduce mortality compared to placebo (RR 0.60, 95% CI 0.40-0.89; 6 studies; low-certainty evidence). Non-pharmacological treatments: Five trials were included in the meta-analyses of non-pharmacological interventions (multi-sensory stimulation, needs assessment, and activities-based interventions); results showed that non-pharmacological interventions may reduce neuropsychiatric symptoms of dementia compared to usual care (SMD -0.33, 95% CI -0.59 to -0.06; low certainty evidence).

CONCLUSIONS

There is moderate-certainty evidence that pharmacological treatments may decrease disease severity and improve function for people with severe dementia. Non-pharmacological treatments are probably effective in reducing neuropsychiatric symptoms but the quality of evidence remains low. There is an urgent need for high-quality evidence for other outcomes and for developing service-user informed interventions for this under-served group.

Analysing the use of music to facilitate social interaction in care home residents with dementia: Narrative synthesis systematic review

INTRODUCTION

Individuals with dementia residing in care homes can rely heavily on care staff to access activities and meaningful interactions. Previous research suggests that care home interactions can be short, fragmented and task-orientated due to staff workload and residents' language impairments. However, music has the potential to be an alternative communication form that remains intact in the later stages of dementia. This systematic review aims to explore how care home music interventions can facilitate social interactions.

METHODS

A narrative synthesis was conducted to explore the mechanisms behind how and why care home music intervention facilitate social interactions. The four-element framework guided analysis; (1) Developing a theory, (2) Developing a preliminary synthesis, (3) Exploring relationships, (4) Assessing robustness.

FINDINGS

The final synthesis included 23 articles. The studies consisted of music therapy sessions, personalised music listening, structured music singing or instrument playing sessions and music therapeutic care. Despite the difference in music interventions, most studies reported an increase in residents' sociable verbal and non-verbal communication and a decrease in unsociable communication. Music interventions allowed residents to reminisce, express themselves, focus and connect with others.

DISCUSSION

The studies highlighted music interventions are accessible to all residents with dementia despite their impairments. The adaptability allows individuals to continue to connect and express themselves even when language deteriorates. More research is needed into the enablers and barriers to implementing interventions into practice, as this systematic review has highlighted that some form of music intervention for all residents can be highly beneficial. Care homes use of music could increase social interactions and meaningful activities.

Rehabilitation in dementia: CST and Sonas group interventions for people with moderate cognitive impairment. A pilot study

Purpose

Dementia is a complex, progressively degenerative condition. It results in loss of cognitive and functional capabilities, along with a significant increase in the level of dependency. A reduction in the use of pharmacological interventions correlates with an increased in good quality non-pharmacological interventions in dementia care. The purpose of this study is to examine the impact of 14-session face-to-face cognitive stimulation therapy (CST) and Sonas group interventions on individuals living with dementia with moderate cognitive impairment, from pre-intervention to post-intervention in terms of their cognition, communication, neuropsychiatric symptoms, activities of daily living and quality of life.

Design/methodology/approach

A pilot single blind prospective controlled trial evaluated two group intervention approaches, cognitive stimulation therapy (CST) and Sonas, with 28 participants with moderate dementia. Pseudorandomisation and single blinding were implemented. CST has a solid evidence base. Sonas is a widely used multi-sensory intervention in Ireland with an emerging evidence base. Participants were recruited from a mental health service. Participants who had a formal diagnosis of dementia, moderate cognitive impairment and some ability to communicate and understand communication were included.

Findings

Results supported CST to a greater extent than Sonas. The CST group showed significant changes in cognition (p = 0.032) and communication (p = 0.006). Both groups had significant changes in carer quality of life (CST, p = 0.019; Sonas, p = 0.035). Results support the recommendations for a future definitive trial.

Research limitations/implications

Rehabilitation potential of individuals living with moderate dementia was demonstrated. This study suggests that group interventions like these impact on the trajectory of dementia.

Practical implications

Rehabilitation interventions impact on the trajectory of dementia. CST and Sonas have no impact on activities of daily living. Future studies with larger sample sizes, 16 weeks intervention period and control groups are required.

Social implications

This pilot study supports CST over Sonas interventions for individuals living with moderate dementia. Multiple outcome measures demonstrated trends towards significance for both interventions. Future definitive trials may detect a significant effect of both interventions.

Originality/value

A dementia diagnosis is devastating and generally creates negative perceptions and associations (Alvira, 2014). In contrast, the outcomes of this study are positive. This study provides evidence that occupational therapist intervention can impact on the trajectory of the condition with people with dementia demonstrating that they do have rehabilitation potential by responding to treatment and improving and maintaining their abilities as they progress through the condition.

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

This scoping review focused on the existing scholarly literature exploring sensory interventions and immersive environments developed for, and used by, older adults living with dementia. The purpose of the scoping review is 1) to understand the various sensory interventions that have been developed, used, and have provided data to show how such interventions are expected to impact the lives of individuals living with dementia; and 2) to understand how the field is moving forward. We chose to map the literature to understand the types of interventions, the types of outcomes measured, and the contexts of their implementation. Our search was constrained to references from 1990 to 1 June 2019 in the following databases: Academic Search Complete, CINAHL Complete, MEDLINE, PsycINFO databases, and Summon Search discovery layer. We screened 2305 articles based on their titles and abstracts, and 465 were sent to full text review, of which 170 were included in our full text extraction. Once the data were extracted, we created emic categories, which emerged from the data, for data that were amenable to categorization (e.g., study setting, intervention type, and outcome type). We developed ten different categories of interventions: art, aromatics, light, multi-component interventions, multisensory rooms, multisensory, music, nature, touch, and taste. Sensory interventions are a standard psychosocial approach to managing the personal expressions commonly experienced by people living with dementia. Our findings can help providers, caregivers, and researchers better design interventions for those living with dementia, to help them selectively choose interventions for particular outcomes and settings. Two areas emerging in the field are nature interventions (replacing traditional "multisensory rooms" with natural environments that are inherently multisensory and engaging) and multi-component interventions (where cognitive training programs are enhanced by adding sensory components).

A systematic review of language and communication intervention research delivered in groups to older adults living in care homes

BACKGROUND

The communication skills of older adults living in care homes is an underexplored topic. Ageing can lead to reduced communication ability and activity; and in the care home environment there may also be fewer communication opportunities. This situation is likely to negatively impact well-being. Previous reviews have found evidence of the effectiveness of behavioural interventions in increasing well-being, but no systematic review to date has focused specifically on the evidence base for group language and communication interventions in this population.

AIMS

To identify and evaluate the evidence for behavioural interventions with older adults, delivered in groups in care homes, that specifically included a language or communication activity. To explore the impact of such intervention on the specific domains of language, communication and social interaction. To determine whether behavioural mechanisms of action can be identified.

METHODS & PROCEDURES

Embase, Medline, Ovid Nursing database, Psych info and CINAHL complete were searched and produced 158 records for screening, of which 22 remained for review. In order to identify and evaluate the quality of the evidence base presented the following research questions were posed: What research has been conducted in this area? What is the methodological quality of the studies identified? How complete is the intervention reporting? How was change measured in the domains of language, communication and social interaction? Is there evidence of efficacy, indicated by statistically significant improvement, in these domains? How did the interventions work? Synthesis tools employed included the PEDro-P Scale, the TIDieR checklist and the ITAX.

MAIN CONTRIBUTION

A total of 22 studies met the criteria for review. One study used solely language or communication interventions, but the remaining 21 studies used behavioural interventions which incorporated language and communication activities to varying degrees. Studies fell into four broad intervention types: reminiscence or life review; cognitive stimulation; narrative or storytelling; and multi-modality group communication. The majority of studies were of fair methodological quality, with a moderate level of detail provided in treatment reporting. Statistically significant improvement was reported by authors in all four intervention types and across language, communication and social domains. Social interaction, social support and behavioural skills were the most consistent mechanisms of action in the reviewed behavioural interventions.

CONCLUSIONS & IMPLICATIONS

Despite limitations in the evidence base, there are important positive signs for the beneficial effects of supporting language and communication in care homes. Blinding of assessors, and the accuracy and accessibility of statistical reporting are important areas to address in order to improve the quality of the evidence base.

WHAT THIS PAPER ADDS

Ageing can lead to reduced communication ability and activity, and in the care home setting there may also be fewer communication opportunities. This situation is likely to negatively impact well-being. Previous reviews have found evidence of the effectiveness of behavioural interventions in increasing well-being. The communication skills of older adults living in care homes is an underexplored topic. No systematic review to date has focused specifically on the evidence base for group language and communication interventions in this population. This review reveals important positive signs for the beneficial effects of supporting language and communication in care homes. Social interaction, social support, and behavioural skills were the most consistent mechanisms of action in the reviewed behavioural interventions.

Systematic review of the current psychosocial interventions for people with moderate to severe dementia

OBJECTIVE

Dementia, a global epidemic, currently affects 50 million individuals worldwide. There are currently limited effective treatments for moderate to severe dementia, and most treatments focus on reducing symptoms rather than improving positive factors. It is unclear if improvements are not possible due to disease severity. This review examines the efficacy of the current psychosocial interventions for people with moderate to severe dementia, focusing on improving cognition and quality of life (QoL) to evaluate what treatments are working and whether improvements are possible.

METHODS

A systematic search was conducted using six key databases to identify psychosocial interventions for people with moderate to severe dementia, measuring cognition or QoL in randomized controlled trials (RCTs), published between 2000 and 2020.

RESULTS

The search identified 4193 studies, and 74 articles were assessed for full-text review. Fourteen RCTs were included and appraised with the Physiotherapy Evidence Database Scale. The included RCTs were moderate in quality.

CONCLUSIONS

Aromatherapy and reminiscence therapy showed the strongest evidence in improving QoL. There was some evidence that aerobic exercise enhanced cognition, and a multicomponent study improved QoL. However, a quality assessment, using pre-specified criteria, indicated many methodological weaknesses. While we found improvements in cognition and QoL for moderate to severe dementia, results must be interpreted with caution. Future interventions with rigorous study designs are a pressing need and required before we can recommend specific interventions.

Effects of the Sonas Program on Anxiety and Depression in Nursing Home Residents with Dementia: A 6-Month Randomized Controlled Trial

Introduction

There is a dearth of evidence about the effects of Sonas, a multisensory stimulation on people with dementia (PWD). The main aim of this study was to examine the effects of the Sonas program on anxiety and depression in nursing home (NH) residents with dementia.

Methods

In all, 120 PWD ≥65 years of age from 6 NHs were included in a randomized control trial and were allocated to 1 of 3 groups for 24 weeks: a Sonas program group (n = 48), a reading group (n = 32), and a control group (n = 40). One hundred and five participants completed follow-up assessments. Anxiety and depression were assessed by the Rating Anxiety in Dementia (RAID) scale and the Cornell Scale for Depression in Dementia (CSDD), respectively. Generalized linear mixed models were estimated to assess trends in the proportion of participants with anxiety (a RAID score ≥11) and depression (a CSDD score ≥10).

Results

No significant reduction in anxiety from baseline to follow-up was observed in any of the groups. Participants in the Sonas group showed a significant reduction in depression from baseline to 12 weeks (p = 0.001) and from baseline to 24 weeks (p = 0.009).

Conclusion

The Sonas program had no effect on severity of anxiety but a reduction in depressive symptoms was found in PWD.

Person-Centered Care in Persons Living with Dementia: A Systematic Review and Meta-Analysis

Background and Objectives

The concept of person-centered care has been utilized/adapted to various interventions to enhance health-related outcomes and ensure the quality of care delivered to persons living with dementia. A few systematic reviews have been conducted on the use of person-centered interventions in the context of dementia care, but to date, none have analyzed intervention effect by intervention type and target outcome. This study aimed to review person-centered interventions used in the context of dementia care and examine their effectiveness.

Research Design and Methods

A systematic review and meta-analysis were conducted. We searched through 5 databases for randomized controlled trials that utilized person-centered interventions in persons living with dementia from 1998 to 2019. Study quality was assessed using the National Institute for Health and Clinical Excellence checklist. The outcomes of interest for the meta-analysis were behavioral and psychological symptoms in dementia (BPSD) and cognitive function assessed immediately after the baseline measurement.

Results

In total, 36 studies were systematically reviewed. Intervention types were reminiscence, music, and cognitive therapies, and multisensory stimulation. Thirty studies were included in the meta-analysis. Results showed a moderate effect size for overall intervention, a small one for music therapy, and a moderate one for reminiscence therapy on BPSD and cognitive function.

Discussion and Implications

Generally speaking, person-centered interventions showed immediate intervention effects on reducing BPSD and improving cognitive function, although the effect size and significance of each outcome differed by intervention type. Thus, health care providers should consider person-centered interventions as a vital element in dementia care.

Nonpharmacological Interventions for Anxiety and Dementia in Nursing Homes: A Systematic Review

Anxiety is a major mental disorder in later life that impacts on activities of daily living and quality of life for adults living with dementia in nursing homes. The aim of this article was to systematically review nonpharmacological interventions for older adults living in nursing homes who experience comorbid anxiety and dementia.

METHOD

A systematic literature search was conducted across key databases (Cinahl, ASSIA, Cochrane reviews and trials, psycARTICLES, psycINFO, and PubMed) to identify studies measuring anxiety as an outcome for an intervention for older adults living with dementia in nursing homes, up to December 31, 2017.

RESULTS

The search yielded a total of 1,925 articles with 45 articles accessed for full article review. A total of 13 articles were included in this review following quality appraisal based on Cochrane methodology with six different anxiety measures used. The studies included were moderate to high-quality randomized control trials although heterogeneity precluded a combined meta-analysis.

CLINICAL IMPLICATIONS

The most common interventions used to address anxiety in this population were music therapy and activity-based interventions although there was limited evidence for the efficacy of either intervention. Little is known about effective nonpharmacological treatment for anxiety for people living with dementia in nursing homes. Further research using consistent measurement tools and time points is required to identify effective interventions to improve the quality of life for people living with both dementia and anxiety in nursing homes.

Effectiveness of multisensory stimulation in managing neuropsychiatric symptoms in older adults with major neurocognitive disorder: a systematic review

OBJECTIVE

The objective of the review was to synthesize the effectiveness of multisensory stimulation in managing neuropsychiatric symptoms (NPS) in older adults with major neurocognitive disorder (NCD).

INTRODUCTION

Major neurocognitive disorder is characterized by changes in specific cognitive domains with a progressive deterioration in cognitive ability and capacity for independent living. Most older adults with this condition have one or more concomitant symptoms known as NPS. Evidence shows that nonpharmacological therapies have been effective in controlling these symptoms, with multisensory stimulation attracting further investigation.

INCLUSION CRITERIA

The review considered studies on older adults aged 65 years or over with major NCD. The intervention of interest was multisensory stimulation, and the comparator was usual care (e.g. no occupational therapy, no cognitive training, and no art therapy, but with possible control of activities such as looking at photographs or doing quizzes), or another intervention (e.g. occupational therapy, cognitive training and art therapy). Primary outcomes were NPS (agitation, aggression, motor disturbances, mood liability, anxiety, apathy, night-time behaviour, eating disorders, delusion and hallucination). Secondary outcomes were quality of life, functional status in activities of daily living, cognitive status and caregiver burden. Experimental study designs were considered.

METHODS

A broad range of keywords and a three-step search strategy were used to identify potentially eligible published and unpublished studies from January 1990 to June 2016 in major healthcare-related online databases. Studies in English, Spanish and Portuguese were included. Two independent reviewers assessed the methodological quality of eight included studies using the Joanna Briggs Institute (JBI) Critical Appraisal Checklists for Randomized Controlled Trials and Quasi-Experimental Studies. Data were extracted using the standardized data extraction tool from the JBI System for the Unified Management, Assessment and Review of Information (JBI SUMARI) and included details about the interventions, populations, study methods and outcomes of interest. Significant differences were found between participants, interventions, outcome measures (clinical heterogeneity), and designs (methodological heterogeneity). For these reasons, a meta-analysis could not be performed. Therefore, the results have been described in a narrative format.

RESULTS

Eight studies (seven randomized controlled trials and one quasi-experimental study) were included, with a total sample of 238 participants (pre-intervention). Four studies confirmed the effectiveness of multisensory stimulation in domains such as physically nonaggressive behavior, verbally agitated behavior and agitation. However, these effects did not always persist in the long-term. Six studies showed poorly consistent results on the effects of multisensory stimulation in improving mood, with only one displaying significant effects. Similarly, despite poor results, two studies showed benefits concerning anxiety. Participants reported significantly decreased levels of anxiety over the course of the intervention, and this improvement persisted in the long-term. In regard to functional status in activities of daily living, two studies reported an improvement in the short-term. Moreover, the effectiveness in cognitive domains such as memory and attention to surroundings also showed inconsistent results across the seven studies that analyzed this outcome. Two studies reflected an improvement during the intervention, but also reported a gradual decline in the long-term. Only one study observed significantly better results during the intervention that persisted until the follow-up assessment. Apathy, night-time behavior, eating disorders, delusion and hallucination were NPS that were not explored in the studies that met the criteria to be included in this review.

CONCLUSIONS

These findings suggest that multisensory stimulation could be an effective intervention for managing NPS in older adults with major NCD in a mild to severe stage, particularly for managing behavioral symptoms such as agitation. This research provides an indication of the likely effect of the multisensory stimulation on NPS such as agitation and anxiety, as well on cognitive status.

Experiences of nurses and other health workers participating in a reflective course on compassion-based care

BACKGROUND

the risk of compassion fatigue in healthcare staff is real, especially when considering the current financial pressures. A course in compassion-based care (CBC) was delivered to mental health staff at a hospital in north-west England, with the intention of rehabilitating ward culture and, subsequently, improving patient experience.

AIMS

to explore staff experiences of participating in the CBC course.

METHODS

a qualitative study using semi-structured interviews with participants (n=12) was conducted. All staff attending the course were eligible and were invited to participate. Interview transcripts were thematically analysed.

FINDINGS

five themes characterising participant experience emerged from the data: meeting a need; creating the space; reorientation; prioritising self-care; and influencing team dynamics. Data overwhelmingly indicated the success of the CBC course.

CONCLUSION

the CBC course appeared to have a profound effect on participants; it should be considered for further rollout and evaluation.

Feasibility of Three Novel Forms of Passive Exercise in a Multisensory Environment in Vulnerable Institutionalized Older Adults with Dementia

BACKGROUND

Increasing physical activity levels in patients with dementia can reduce pathology severity and progression of the disease. However, physical activity programs can be challenging to adhere to for this vulnerable population. Three novel forms of passive exercise in a multisensory environment may be feasible alternatives for patients who can no longer be involved in physical activity.

OBJECTIVE

To determine the feasibility of three different forms of passive exercise in a multisensory environment in inactive institutionalized older adults with dementia.

METHODS

120 patients with dementia participated in this single blind randomized controlled trial (64.5% female, age 85.3±6.8 years Mini-Mental State Examination range 0-29). Ninety participants were randomly assigned to one of the three intervention groups: Therapeutic Motion Simulation (TMSim), Whole Body Vibration (WBV), and TMSim + WBV. Participants received 6 weeks of passive exercise, 4 sessions a week, 4 (WBV) to 12 (TMSim and TMSim + WBV) minutes per session. Feasibility of the novel forms of passive exercise was evaluated based on attendance, compliance, (proxy) experience scores, adverse events and drop-out rates.

RESULTS

On average 87.9% of the offered intervention sessions were attended. All three forms of passive exercise were well appreciated by the participants (7.3 on a scale from 0 to 10). Intervention related drop-out rates were reasonable (12.2%) and no serious adverse events occurred.

CONCLUSION

The novel passive exercise interventions TMSim, WBV, and TMSim + WBV are feasible to apply in patients at all stages of dementia. More research is needed to establish effectiveness of passive exercise to limit adverse effects of dementia.

[Quality of life of nursing home residents with dementia before, during and after playing with a magic table]

The 'Active Cues Magic Table' is a new game concept within nursing home care. It consists of light animations projected on a dining table and responding to movements of the players. The aim of this exploratory, quasi-experimental study was to examine the quality of life of nursing home residents with moderately severe or severe dementia before, during and after playing with this magic table. Quality of life was assessed with the Qualidem and the DS-DAT. Of the 34 nursing home residents included, 62% were female and mean age was 86.5 years (standard deviation 6.2). The Qualidem showed a small to moderate improvement in 'negative affect', 'restless tense behavior' and 'positive self-image' up to the week after playing (p ≤ 0.04). The DS-DAT showed a moderate improvement up to one hour after playing compared to a quarter of an hour before playing (p < 0.001). In conclusion, the quality of life of nursing home residents with moderately severe or severe dementia seems to improve up to the week after playing with the magic table. However, future research is needed to confirm the results of this exploratory study and to examine whether the improvements can truly be ascribed to the magic table.

A Systematic Review and Meta-Analysis of Nonpharmacological Interventions for Moderate to Severe Dementia

OBJECTIVE

Due to limited efficacy of medications, non-pharmacological interventions (NPI) are frequently co-administered to people with moderate to severe dementia (PWMSD). This systematic review and meta-analysis investigated the effects of NPI on activities of daily living (ADL), behavioral and psychological symptoms of dementia (BPSD), and cognition and quality of life (QoL) of PWMSD.

METHODS

A literature search was conducted in the following databases: Cochrane CENTRAL, EMBASE, Medline, CIHNAL, PsycINFO, KoreaMED, KMbase, and KISS. We conducted a meta-analysis on randomized controlled trials and used the generic inverse variance method with a fixed-effects model to calculate the standardized mean difference (SMD). The protocol had been registered (CRD42017058020).

RESULTS

Ten randomized controlled trials met the inclusion criteria of the current meta-analysis. NPI were effective in improving ADL [SMD=0.28, 95% confidence interval (CI)=0.11-0.45] and reducing depression (SMD=-0.44, 95% CI=-0.70- -0.19). However, NPI were not effective in reducing agitation, anxiety, or overall, or improving cognitive function. In a subgroup analysis, music therapy was effective in reducing overall BPSD (SMD=-0.52, 95% CI=-0.90- -0.13).

CONCLUSION

Albeit the number of studies was limited, NPI improved ADL and depression in PWMSD.

Impact of the Sonas Programme on Communication over a Period of 24 Weeks in People with Moderate-to-Severe Dementia

Objectives

The primary aim was to examine how communication abilities changed over time among nursing home residents with moderate-to-severe dementia who were attending the Sonas programme and to explore whether changes in communication abilities were related to cognitive ability.

Method

A longitudinal secondary descriptive study method was employed, where 56 people with moderate-to-severe dementia attended a 45-min Sonas group session twice a week for 24 weeks. The Threadgold Communication Tool (TCT) was completed every 4 weeks.

Results

The impact of the Sonas programme on communication showed a significant non-linear trend in the TCT, with an increase in communication abilities during the first 16 weeks, regardless of the level of the residents' cognitive abilities. Thereafter it levelled out. No interaction was found between time and the frequency of attendances at Sonas sessions. Both verbal and non-verbal communication increased from the baseline, with non-verbal communication increasing quickly and verbal communication increasing marginally.

Conclusion

Communication abilities increased with the time of the intervention, but the peak was achieved after 16 weeks, after which the effect levelled out. This suggest that the Sonas programme should be used for a period of at least 16 weeks before evaluating its effect.

Can musical intervention improve memory in Alzheimer's patients? Evidence from a systematic review

Treatment with music has shown effectiveness in the treatment of general behavioural and cognitive symptoms of patients with various types of dementia.

Objective

To assess the effectiveness of treatment with music on the memory of patients with Alzheimer's disease (AD).

Methods

A systematic search was performed on PubMed (Medline), Cochrane Library, PsycINFO and Lilacs databases up to June 2017 and included all randomized controlled trials that assessed memory using musical interventions in patients with AD.

Results

Forty-two studies were identified, and 24 studies were selected. After applying the exclusion criteria, four studies involving 179 patients were included. These studies showed the benefits of using music to treat memory deficit in patients with AD.

Conclusion

To the best of our knowledge, this is the first systematic review focusing on randomized trials found in the literature that analysed the role of musical interventions specifically in the memory of patients with AD. Despite the positive outcome of this review, the available evidence remains inconsistent due to the small number of randomized controlled trials.

Reporting quality of music intervention research in healthcare: A systematic review

INTRODUCTION

Concomitant with the growth of music intervention research, are concerns about inadequate intervention reporting and inconsistent terminology, which limits validity, replicability, and clinical application of findings.

OBJECTIVE

Examine reporting quality of music intervention research, in chronic and acute medical settings, using the Checklist for Reporting Music-based Interventions. In addition, describe patient populations and primary outcomes, intervention content and corresponding interventionist qualifications, and terminology.

METHODS

Searching MEDLINE, PubMed, CINAHL, HealthSTAR, and PsycINFO we identified articles meeting inclusion/exclusion criteria for a five-year period (2010-2015) and extracted relevant data. Coded material included reporting quality across seven areas (theory, content, delivery schedule, interventionist qualifications, treatment fidelity, setting, unit of delivery), author/journal information, patient population/outcomes, and terminology.

RESULTS

Of 860 articles, 187 met review criteria (128 experimental; 59 quasi-experimental), with 121 publishing journals, and authors from 31 countries. Overall reporting quality was poor with <50% providing information for four of the seven checklist components (theory, interventionist qualifications, treatment fidelity, setting). Intervention content reporting was also poor with <50% providing information about the music used, decibel levels/volume controls, or materials. Credentialed music therapists and registered nurses delivered most interventions, with clear differences in content and delivery. Terminology was varied and inconsistent.

CONCLUSIONS

Problems with reporting quality impedes meaningful interpretation and cross-study comparisons. Inconsistent and misapplied terminology also create barriers to interprofessional communication and translation of findings to patient care. Improved reporting quality and creation of shared language will advance scientific rigor and clinical relevance of music intervention research.

Reminiscence therapy for dementia

BACKGROUND

This updated Cochrane Review of reminiscence therapy (RT) for dementia was first published in 1998, and last updated in 2005. RT involves the discussion of memories and past experiences with other people using tangible prompts such as photographs or music to evoke memories and stimulate conversation. RT is implemented widely in a range of settings using a variety of formats.

OBJECTIVES

To assess the effects of RT on people living with dementia and their carers, taking into account differences in its implementation, including setting (care home, community) and modality (group, individual).

SEARCH METHODS

We searched ALOIS (the Cochrane Dementia and Cognitive Improvement Group's Specialized Register) on 6 April 2017 using the search term 'reminiscence.'

SELECTION CRITERIA

We included all randomised controlled trials of RT for dementia in which the duration of the intervention was at least four weeks (or six sessions) and that had a 'no treatment' or passive control group. Outcomes of interest were quality of life (QoL), cognition, communication, behaviour, mood and carer outcomes.

DATA COLLECTION AND ANALYSIS

Two authors (LOP and EF) independently extracted data and assessed risk of bias. Where necessary, we contacted study authors for additional information. We pooled data from all sufficiently similar studies reporting on each outcome. We undertook subgroup analysis by setting (community versus care home) and by modality (individual versus group). We used GRADE methods to assess the overall quality of evidence for each outcome.

MAIN RESULTS

We included 22 studies involving 1972 people with dementia. Meta-analyses included data from 16 studies (1749 participants). Apart from six studies with risk of selection bias, the overall risk of bias in the studies was low.Overall, moderate quality evidence indicated RT did not have an important effect on QoL immediately after the intervention period compared with no treatment (standardised mean difference (SMD) 0.11, 95% confidence interval (CI) -0.12 to 0.33; I² = 59%; 8 studies; 1060 participants). Inconsistency between studies mainly related to the study setting. There was probably a slight benefit in favour of RT in care homes post-treatment (SMD 0.46, 95% CI 0.18 to 0.75; 3 studies; 193 participants), but little or no difference in QoL in community settings (867 participants from five studies).For cognitive measures, there was high quality evidence for a very small benefit, of doubtful clinical importance, associated with reminiscence at the end of treatment (SMD 0.11, 95% CI 0.00 to 0.23; 14 studies; 1219 participants), but little or no difference at longer-term follow-up. There was a probable slight improvement for individual reminiscence and for care homes when analysed separately, but little or no difference for community settings or for group studies. Nine studies included the widely used Mini-Mental State Examination (MMSE) as a cognitive measure, and, on this scale, there was high quality evidence for an improvement at the end of treatment (mean difference (MD) 1.87 points, 95% CI 0.54 to 3.20; 437 participants). There was a similar effect at longer-term follow-up, but the quality of evidence for this analysis was low (1.8 points, 95% CI -0.06 to 3.65).For communication measures, there may have been a benefit of RT at the end of treatment (SMD -0.51 points, 95% CI -0.97 to -0.05; I² = 62%; negative scores indicated improvement; 6 studies; 249 participants), but there was inconsistency between studies, related to the RT modality. At follow-up, there was probably a slight benefit of RT (SMD -0.49 points, 95% CI -0.77 to -0.21; 4 studies; 204 participants). Effects were uncertain for individual RT, with very low quality evidence available. For reminiscence groups, evidence of moderate quality indicated a probable slight benefit immediately (SMD -0.39, 95% CI -0.71 to -0.06; 4 studies; 153 participants), and at later follow-up. Community participants probably benefited at end of treatment and follow-up. For care home participants, the results were inconsistent between studies and, while there may be an improvement at follow-up, at the end of treatment the evidence quality was very low and effects were uncertain.Other outcome domains examined for people with dementia included mood, functioning in daily activities, agitation/irritability and relationship quality. There were no clear effects in these domains. Individual reminiscence was probably associated with a slight benefit on depression scales, although its clinical importance was uncertain (SMD -0.41, 95% CI -0.76 to -0.06; 4 studies; 131 participants). We found no evidence of any harmful effects on people with dementia.We also looked at outcomes for carers, including stress, mood and quality of relationship with the person with dementia (from the carer's perspective). We found no evidence of effects on carers other than a potential adverse outcome related to carer anxiety at longer-term follow-up, based on two studies that had involved the carer jointly in reminiscence groups with people with dementia. The control group carers were probably slightly less anxious (MD 0.56 points, 95% CI -0.17 to 1.30; 464 participants), but this result is of uncertain clinical importance, and is also consistent with little or no effect.

AUTHORS' CONCLUSIONS

The effects of reminiscence interventions are inconsistent, often small in size and can differ considerably across settings and modalities. RT has some positive effects on people with dementia in the domains of QoL, cognition, communication and mood. Care home studies show the widest range of benefits, including QoL, cognition and communication (at follow-up). Individual RT is associated with probable benefits for cognition and mood. Group RT and a community setting are associated with probable improvements in communication. The wide range of RT interventions across studies makes comparisons and evaluation of relative benefits difficult. Treatment protocols are not described in sufficient detail in many publications. There have been welcome improvements in the quality of research on RT since the previous version of this review, although there still remains a need for more randomised controlled trials following clear, detailed treatment protocols, especially allowing the effects of simple and integrative RT to be compared.

Managing behavioral and psychological symptoms in Chinese elderly with dementia via group-based music intervention: A cluster randomized controlled trial

The present study aimed to evaluate the effects of a group music intervention in managing behavioral and psychological symptoms in Chinese elderly with dementia. This cluster randomized trial recruited 73 elderly participants with moderate dementia from 10 elderly residential homes and assigned them to the intervention ( n = 40) and control ( n = 33) group. The intervention included 16 half-hour sessions of music intervention with multi-sensory components over eight weeks and control group received standard care. Participants’ levels of subjective moods and neuropsychiatric symptoms such as agitation, aberrant motor behaviors, dysphoria, and irritability were assessed at baseline, the 2nd, 4th, 6th, and the end of the intervention. Controlling for baseline outcomes, latent growth modeling revealed significant intervention effects for agitation ( B = −1.03, SE = 0.30, p < 0.01), aberrant motor behavior ( B = −1.80, SE = 0.66, p < 0.01), and dysphoria ( B = −0.79, SE = 0.36, p < 0.05), with the intervention group showing improvements compared to no substantial changes in the control group. There were no significant intervention effects on irritability or subjective mood ( p > 0.05). The music intervention showed significant reduction in the behavioral and psychological symptoms in Chinese elderly patients with dementia. Elderly homes could adopt this practical non-pharmacological intervention as a strategy to improve the well-being of the elderly.

Does music therapy enhance behavioral and cognitive function in elderly dementia patients? A systematic review and meta-analysis

Demographic aging is a worldwide phenomenon, cognitive and behavioral impairment is becoming global burden of nerve damage. However, the effect of pharmacological treatment is not satisfying. Therefore, we analyzed the efficacy of music therapy in elderly dementia patients, and if so, whether music therapy can be used as first-line non-pharmacological treatment. A comprehensive literature search was performed on PubMed, EMbase and the Cochrane Library from inception to September 2016. A total of 34 studies (42 analyses, 1757 subjects) were included; all of them had an acceptable quality based on the PEDro and CASP scale scores. Studies based on any type of dementia patient were combined and analyzed by subgroup. The standardized mean difference was -0.42 (-0.74 to -0.11) for disruptive behavior and 0.20 (-0.09 to 0.49) for cognitive function as primary outcomes in random effect models using controls as the comparator; the secondary outcomes were depressive score, anxiety and quality of life. No evidence of publication bias was found based on Begg's and Egger's test. The meta-analysis confirmed that the baseline differences between the two groups were balanced. Subgroup analyses showed that disease sub-type, intervention method, comparator, subject location, trial design, trial period and outcome measure instrument made little difference in outcomes. The meta-regression may have identified the causes of heterogeneity as the intervention method, comparator and trial design. Music therapy was effective when patients received interactive therapy with a compared group. There was positive evidence to support the use of music therapy to treat disruptive behavior and anxiety; there were positive trends supporting the use of music therapy for the treatment of cognitive function, depression and quality of life. This study is registered with PROSPERO, number CRD42016036153.

Effect of the Sonas Programme on Communication in People with Dementia: A Randomized Controlled Trial

Background

Strategies to improve communication in people with dementia are warranted. We examined the effect of the Sonas programme on communication ability in persons with moderate to severe dementia.

Methods

A 24-week 3-armed (Sonas, reading, and control group) randomized controlled trial including 120 nursing home residents with dementia was conducted; 105 completed the follow-up assessments. The main outcome was change in communication abilities measured by the Holden Communication Scale (HCS).

Results

We found no overall significant effect of the Sonas programme with regard to communication ability as measured by the HCS. However, an effect between the Sonas group and the reading group and between the Sonas group and the control group from T0 to T1 and T2 was found, as well as a significant improvement in communication in the Sonas group. Among people with severe dementia, the Sonas group scored significantly better on the HCS compared to the reading group after 12 weeks, but not after 24 weeks.

Conclusion

This study failed to document an overall effect of the Sonas programme on communication; however, the findings indicate that the Sonas programme has a significant effect on communication among those with severe dementia.

Evidence-based Non-pharmacologic Interventions for Managing Neuropsychiatric Symptoms and Mental Health Issues in Residents in Assisted Living

THE PROBLEM

Mental health issues such as depression and neuropsychiatric symptoms (NPS) (e.g. agitation, aggression, rejection of care, wandering) are prevalent among residents in Assisted Living Facilities (ALF). Historically, these issues have only been treated with medications that can have a high risk of adverse effects in this population. This paper presents a scoping review of nonpharmacological interventions tested in ALFs for two of the most prevalent mental health issues: depression and NPS.

KEY FINDINGS

Thirteen studies met inclusion criteria. Of those, eight (61.5%) found positive outcomes. Activity based and music therapy that utilize customization to interests and abilities showed the most promise.

TIPS FOR SUCCESS

Based on findings we offer five recommendations: 1) adopt evidence-based or evidence-informed interventions; 2) use tailored activity as a therapeutic modality; 3) adopt new training approaches for staff; 4) use emerging technologies for training and intervention; and 5) participate in practice based research.

A Psychometric Evaluation of the Threadgold Communication Tool for Persons with Dementia

Background

The objective of this study was to investigate the psychometric properties of the Threadgold Communication Tool (TCT).

Method

Internal consistency reliability was measured using Cronbach's α coefficient and inter-item correlation. Test-retest was performed to examine the instrument's stability. Exploratory principal component analysis (PCA) with oblimin rotation was carried out to evaluate construct validity. Finally, the score on each item of the TCT was correlated with the person's Mini Mental State Examination (MMSE) and Barthel Index of activities of daily living scores.

Results

A total of 51 persons participated, with a mean age of 86.7 (SD 6.6) years, of whom 46 were women with moderate-to-severe dementia [mean MMSE score 7.5 (SD 6.7)]. There were two measurement points 2 weeks apart. The results showed a satisfactory level for internal consistency and a high test-retest reliability (r = 0.76). The corrected item-total correlation ranged between 0.50 and 0.87, and a two-factor structure was revealed at the PCA. ‘Vocalizing’ seemed to measure another aspect of communication and was the only item which was negatively loaded.

Conclusion

Despite the low sample size in this study, the results revealed the TCT as a reliable and valid instrument, suitable for measuring communication among people with dementia. We suggest clarifying the understanding of ‘vocalizing’ before considering removing it from the scale.
