Effectiveness of personalized music systems to influence neuropsychiatric symptoms associated with dementia: A quasi-experimental study

ContextStudies have shown that music can improve the neuropsychiatric symptoms in people with dementia. Personalized music has the greatest impact. However, people with dementia in residential care rarely listen to personalized music; in doing so, they themselves as well as their caregivers pass up the positive effects associated with it. As a result, customizable music systems have been developed that allow people with dementia to listen to their favorite music. AimTo determine the effectiveness of personalized music systems on the neuropsychiatric symptoms of people with dementia in residential care and the perceived distress of caregivers. Method14 residents heard personalized music during personal care for eight weeks. Outcomes were derived from pre-post-follow up assessments of residents' neuropsychiatric symptoms and caregivers' distress using the Neuropsychiatric Inventory Questionnaire (NPI-Q). The frequency of the music systems' usage was recorded in log files. A control group of 14 residents received standard care. ResultsCaregivers used the music systems among the residents with varying frequency. During the intervention, an increasing trend of the severity value of apathy was observed, while the severity values of delusions and nighttime disturbances tended to decrease. However, the trends did not reach statistical significance. Caregivers' perceived distress was not affected. ConclusionA practicable solution for providing personalized music to people with dementia in residential care was tested. Possible positive effects were observed for delusions and nighttime disturbances in people with dementia, but a larger study will be required to verify these observations.

Care for older adults with dementia: PACE day care or residential dementia care units?

BackgroundPersons with dementia (PwD) are at greater risk for various adverse health outcomes, and the best care model remains to be determined. This study aimed to compare the physical and neurocognitive performance of PwD in the Program of All-inclusive Care for the Elderly (PACE) and residential dementia care units. MethodsThis was a case-control study comparing outcomes between care recipients of PACE services (PC group) and residential dementia care (RC group). Demographic characteristics, underlying diseases, physical function, cognitive function, mood status, and behavioral and psychotic symptoms of dementia (BPSDs) were assessed every 3-6 months in both groups, while frailty status and Timed Up-and-Go Test (TUGT) performance were assessed every 6 months in the PC group only. ResultsOverall, 96 participants (PC group: 25, RC group: 71; mean age: 86.4 ± 6.8 years) were enrolled with the median follow-up period of 43.6 weeks. Lower incidence of hospital admissions was noted in the PC group (0.52 ± 1.12 vs 1.38 ± 2.49 admissions/1,000 person-days, p=0.023), even though the PC group had higher multimorbidity and more severe BPSDs. During the study period, the PC group showed a significant improvement in body mass index, less physical dependence, better cognitive performance and reduced depressive mood. In addition, the PC group showed improvement in frailty, leisure hour activities, and TUGT results. However, participants in the PC group were more likely to experience BPSD deterioration (β coeff.: 0.193, 95% CI: 0.121- 0.265). ConclusionThe PACE services significantly reduced unexpected hospital admissions of PwD, facilitated the maintenance of physical independence, and improved cognitive performance and mood status. Further randomized controlled studies are needed to determine the most appropriate care model for PwD.

The Perspectives of Professional Caregivers on Implementing Audio-Based Technology in Residential Dementia Care.

Music and familiar everyday sounds can be meaningful for people with dementia by providing benefits such as evoking memories and emotions or prompting social interactions with caregivers or relatives. Motivated by this potential, researchers and designers are investigating how to leverage these beneficial effects of sound in care environments through audio-based technology. However, there is a gap in the knowledge of how audio-based technology can be successfully implemented within everyday care practice. In this paper, we present the outcome of three participatory workshops with 18 professional caregivers to explore how audio-based technology can add value to existing care processes and activities in residential dementia care. During the participatory workshops, professional caregivers (1) mapped existing care activities; (2) linked findings in research with practice, and (3) designed scenarios for the Vita sound cushion. Care professionals indicate how audio-based technology can support existing care practice by influencing the mood of residents and by supporting social interaction during moments of care, daytime activities, or situational sessions. This study bridges research findings with insights from practice, contributing to a shared understanding of opportunities for embedding audio-based technology in dementia care. These opportunities motivate future research to implement and evaluate audio-based technology in residential dementia care.

Why we need to care about the care: A longitudinal study linking the quality of residential dementia care to residents’ quality of life

BackgroundResidential dementia care staff are often the most important people in a resident’s social world. It is a symbiotic relationship and the work can involve highly emotional interactions as well as physical and technical demands. This study focused on narrowing down the most useful targets for intervention in quality of care (QOC) in order to improve quality of life (QOL) for people with dementia in residential care. MethodOver six months we followed: 247 older adults with dementia from 12 residential care facilities, their families/care partners (n = 225), managers (n = 12) and staff (n = 232). Facilities ranged from 10 to 137 beds, located across remote, rural and metropolitan areas. Measures: Staff surveys, family member and resident interviews, resident file audits, live resident and staff observations and organisational audits. ResultsThe QOC provided had an immediate impact on resident’s pain, depression, QOL scale score, Body Mass Index, ease/engagement with staff, and food and fluid intake. This influence was still evident six months later, with baseline QOC leading to improved ease and engagement with staff, QOL scores, and fluid intake. Restraint use featured heavily as a predictor of poor outcomes for residents. QOC did not significantly impact agitated behaviours, frailty, nor physical/verbal expressions of well-being. ConclusionsWhat staff do and the way they do it has a real and lasting impact on the QOL of residents. The most useful targets for improving QOL are: eradicating physical restraint and supporting and upskilling care staff so that they treat and interact empathetically and humanely with residents.

Systematic Use of Song and Music in Dementia Care: Health Care Providers' Experiences.

Background and AimUsing song and music in a systematic way in residential dementia care may have several positive impacts on the patients, as well as the care providers. The aim of this study was to explore how health care providers experienced taking responsibility for conducting a song and music program in dementia care in nursing homes.MethodsAn explorative, qualitative study design was used. Focus groups were formed by 17 health care providers from 3 different nursing homes. These providers had experience implementing and using the “Gjenklang” (“reverberation”) song and music program especially developed for people with dementia. Focus group interviews were transcribed verbatim, and systematic text condensation was used for analysing the data.ResultsThree categories with associated subcategories emerged from the analysis process. The categories were 1) the music program increased the staff’s consciousness and awareness; 2) the music program evoked the patients’ emotions and reactions; and 3) maintaining enthusiasm over time.ConclusionThe general opinion among the participants was that using the song and music program in a systematic and planned way had many benefits and positive impacts on the patients, as well as the staff. However, it was challenging to make it a part of the daily routine. Thus, it is important that the leaders of the units take responsibility to ensure continuity and maintain engagement among the staff over time.

Sources of well-being for older adults with and without dementia in residential care: relations to presence of meaning and life satisfaction

Objectives To explore what sources of well-being are rated meaningful by older adults in residential care and how they are related to two important well-being outcomes. Method Two cross-sectional questionnaire studies were conducted in a sample of care residents without cognitive disability (n = 329) and with Alzheimer’s disease (n = 104). Structural equation modelling was used to test a hypothesized and exploratory model of different sources as predictors of presence of meaning in life (POM) and satisfaction with life (SWL). Results Family and Health were rated most meaningful by residents with and without dementia. In both studies, the hypothesized model showed adequate fit with the data. For cognitively intact residents, Personal Growth, Spirituality/Religion, and Interpersonal Relationships predicted POM, while Family and Leisure predicted SWL. Exploratory testing identified Leisure as a possible additional predictor of POM. For residents with Alzheimer’s disease, Personal Growth and Society/Community predicted POM, while Family predicted SWL. Conclusion For older adults in residential care, many sources of well-being remain highly meaningful and some are directly related to the experience of meaning and life satisfaction. Both for residents with and without dementia, continued or increased investment in moments that foster personal growth and family relationships might be especially valuable.

Love, Intimacy and Sexuality in Residential Dementia Care: A Client Perspective

ABSTRACT Objectives: Residential care facility (RCF) residents with dementia are highly dependent on care. This can influence their experience of intimacy and sexuality. The perspective of residents and their spouses with regard to love, intimacy, and sexuality were explored and analyzed. Methods: The study was designed using the IPA methodology. Eight in-depth interviews were held with 12 participants: four couples and four individual residents with dementia. Results: Varied stories were shared; however, dementia had a great impact on all of them. Love, intimacy, and being together were considered fundamentally important by both couples and individual participants, although profound dilemmas were encountered. While only one couple experienced physical sexuality within the RCF, other participants reported that love and being intimate were the most important aspects of their current relationship. Regarding the possibility of fulfilling their needs within the RCF, a secure feeling of privacy was considered to be important, but was absent at the time of the survey. Conclusions: Although challenging to appropriately facilitate at RCFs, love, intimacy, and sexuality are still important aspects for residents with dementia and their spouses. Clinical implications: This study addresses these dilemmas and ads to the normalization of love, intimacy, and sexuality within RCF settings; the findings will hopefully improve the wellbeing of residents with dementia and that of their spouses.

Biographical films as a person-centered approach to reduce neuropsychiatric symptoms of dementia in residential care: A feasibility study.

Neuropsychiatric symptoms are a major component of dementia irrespective of severity or subtype. We aimed to determine the feasibility of biographical films to reduce neuropsychiatric symptoms in people with moderate to severe dementia over a 32-week period. A total of 11 people with dementia situated in a residential care home took part in this mixed-method feasibility study. Carers reported neuropsychiatric symptoms of residents at three time-points, and their experience of the study was obtained at a feedback session. There was a significant reduction in neuropsychiatric symptoms in residents with neuropsychiatric impairment from baseline to the end of study (p = .042; d = .98). Thematic analysis identified three major themes: Triggered memories, knowledge gained to support care, and perceived changes in the resident. The findings suggest that it is feasible to use biographical films long-term to reduce neuropsychiatric symptoms of dementia, alongside routine care.

Connections with nature for people living with dementia

Purpose The benefits of “green dementia care”, whereby people living with dementia are supported to connect with nature, are increasingly being recognised. Evidence suggests that these benefits span physical, emotional and social spheres and can make a significant contribution towards quality of life. However, care settings often present specific challenges to promoting such connections due to a range of factors including risk-averse cultures and environmental limitations. The purpose of this paper is to report on a project that aims to explore the opportunities, benefits, barriers and enablers to interaction with nature for people living with dementia in residential care and extra care housing schemes in the UK. Design/methodology/approach Data were gathered from 144 responses to an online survey by managers/staff of extra care housing schemes and care homes in the UK. In depth-case studies were carried out at three care homes and three extra care housing schemes, involving interviews with residents, staff and family carers. Findings A wide variety of nature-based activities were reported, both outdoor and indoor. Positive benefits reported included improved mood, higher levels of social interaction and increased motivation for residents, and greater job satisfaction for staff. The design and layout of indoor and outdoor spaces is key, in addition to staff who feel enabled to promote connections with nature. Research limitations/implications This paper is based on a relatively small research project in which the participants were self-selecting and therefore not necessarily representative. Practical implications The paper makes some key recommendations for good practice in green dementia care in extra care housing and care homes. Social implications Outdoor activities can promote social interaction for people living with dementia in care settings. The authors’ findings are relevant to the recent policy focus on social prescribing. Originality/value The paper makes some key recommendations for good practice in green dementia care in extra care housing and care homes.

How Should We Capture Health State Utility in Dementia? Comparisons of DEMQOL-Proxy-U and of Self- and Proxy-Completed EQ-5D-5L

BackgroundDementia-specific and proxy-completed preference-based measures have been proposed for use in intervention studies involving people living in residential care, in instances where generic, self-reported preference-based measures have been deemed inappropriate. ObjectiveThis study was conducted to investigate the construct validity, criterion validity, and responsiveness of DEMQOL-Proxy-U and of self- and proxy-completed EQ-5D-5L. MethodsThe analysis used a 3-wave, individual-level data set of 1004 people living with dementia in residential care that included self-completed EQ-5D-5L and formal-carer and informal-carer proxy-completed EQ-5D-5L and DEMQOL-Proxy-U utility values, in addition to other nonutility cognitive measures (Functional Assessment Staging [FAST], Clinical Dementia Rating [CDR], Cohen-Mansfield Agitation Inventory [CMAI]) and health-related quality of life (HRQOL) measures (nursing home version of the Quality of Life with Alzheimer's disease scale [QOL-AD-NH], Quality of Life in Late-Stage Dementia [QUALID] scale). Construct validity, criterion validity, and responsiveness were assessed using correlation, Bland-Altman plots, and panel data regression models. ResultsSelf-completed EQ-5D-5L failed to reflect clinically important differences and changes in FAST, CDR, and CMAI but did capture the resident's own view of HRQOL (QOL-AD-NH). As dementia severity increased, collection of EQ-5D-5L-proxy and DEMQOL-Proxy-U data was more feasible than collection of self-completed EQ-5D-5L. These formal-carer and informal-carer proxy measures also better reflected changes in FAST, CDR, and CMAI but did not capture the resident's own view of HRQOL (QOL-AD-NH), despite adequately capturing the proxy's own view of the resident's HRQOL (QUALID). This indicates discrepancies between a proxy's view and resident's view of the impact that tangible declines in health, cognition, or functional abilities have on HRQOL. The EQ-5D-5L-proxy and DEMQOL-Proxy-U were generally poor substitutes. Regardless of which proxy completed it, the EQ-5D-5L-proxy was typically more responsive than the DEMQOL-Proxy-U to changes in CDR, FAST, and CMAI, indicating that use of the DEMQOL-Proxy-U is not always justified. ConclusionDisparities in the measurement properties of different utility measures mean that choices about how to measure utility in trials could affect economic evaluation outcomes and hence how resources are allocated for dementia care.

Practices for making residents’ wishes fit institutional constraints: a case of manipulation in dementia care

Purpose: The study aims to show how practices of manipulation are used by a member of staff in a care situation where the member of staff has to perform two tasks at once.Method: The study is an ethnomethodological conversation analytic single-case study of a care situation in residential dementia care. The analyses are based on video recordings and observations conducted during 9 months of fieldwork at a residential care facility for persons with dementia. Results: The study details the methods by which a member of staff engages in manipulation by constructing her actions as responses to a resident's wish which has in fact never been stated.Conclusion: The study discusses how manipulation may be understood as care staff practices for making a residents’ wishes fit the institutional constraints they are subjected to and for “doing what is best for the resident.”

Non-pharmacological interventions for people with dementia: A review of reviews.

Aged care services increasingly respond to the needs of people with dementia. Non-pharmacological approaches are preferable to reduce responsive behaviours, improve/maintain functional capacity and reduce emotional disorders. This rapid review of systematic reviews aimed to consolidate the evidence for non-pharmacological interventions and determine outcome effectiveness. Systematic review literature was comprehensively searched for non-pharmacological interventions for dementia in residential care. Quality ratings used adapted GRADE methodology, and ease of implementation assessed. Of 629 abstracts screened, 81 full-text articles were retrieved, 38 articles included. The strongest evidence for reducing responsive behaviours was music, sensory stimulation, simulated presence and validation therapies. Exercise and light therapy improved/maintained activities of daily living, while cognitive stimulation and reminiscence improved cognition. Strongest evidence for reducing emotional disorders was music, psychological interventions and reminiscence. Much evidence of varying quality exists, with resource-constrained residential care providers now able to make evidence-based decisions about non-pharmacological interventions.

A novel method of proxy reporting questionnaire based measures of health-related quality of life of people with dementia in residential care: a psychometric evaluation.

BackgroundIn research in residential care, health-related quality of life (HRQL) is usually measured using either observational methods or standardized questionnaires. DEMQOL-Proxy is a standardized questionnaire measuring HRQL of people with dementia and is usually reported by a family carer. However, not all residents have a family carer who visits often enough to act as a proxy.ObjectivesWe evaluated the psychometric performance of DEMQOL-Proxy when reported on behalf of people with dementia in residential care by a “trained proxy” (DEMQOL-Proxy-TP).ParticipantsWe recruited a sample of 87 people with dementia living in care homes around the UK.MethodsWe used modern psychometric methods (based on the Rasch model) to evaluate DEMQOL-Proxy-TP (on behalf of 85 residents) in a cross-sectional study. We evaluated scale-to-sample targeting, ordering of item thresholds, item fit to the model and differential item functioning (sex, age, type of dementia), local independence, unidimensionality and reliability on the full set of items (31 items) and also a smaller item set (26 items).ResultsThe smaller item set (DEMQOL-Proxy-TP-26) performed better than the original item set and was found to fit the model (p = 0.68). Nevertheless, 17 items were found to have disordered thresholds, and 24 pairs of items showed local dependency (residual correlations >0.3). There were also some areas where scale-to-sample targeting could be improved.ConclusionAfter resolving the identified anomalies, DEMQOL-Proxy-TP can provide adequate measurement of HRQL of people with dementia living in residential care, particularly when no family carer is available. This can be interpreted at the group level but is not yet robust enough for use at the individual level. Future work will compare these results with the psychometric performance of DEMQOL-Proxy reported by family carers and DEMQOL self-reported by the residents.

Meaningful engagement and person-centered residential dementia care: A critical interpretive synthesis

Background: People with moderate to advanced dementia living in residential care are at risk of occupational deprivation. Person-centered care has been adopted as a guiding principle in the provision of residential care for older adults with dementia. In this context, there has been shift in occupational therapy practice from addressing occupational performance towards focusing on meaningful engagement. While both meaningful engagement and person-centered care have been well researched the relationship between the two concepts is poorly understood.Aim: A critical interpretative synthesis was conducted to determine how principles of person-centered care inform occupational therapy practice in relation to promotion of meaningful engagement among residents with moderate to advanced dementia.Methods: A systematic search of research addressing meaningful engagement of people with moderate to advanced dementia identified 26 papers.Results: Papers were classified as theoretical papers and empirical research. Two overarching constructs emerged, namely promoting a culture of collaborative care and understanding the resident as a person with a past, present and future.Conclusions: Occupational deprivation prevails and person-centered care is not fully addressed if opportunities for growth and engagement for residents with moderate to advanced dementia is not extended beyond their life history.Significance: Creating continued opportunities for building agency of residents with dementia could promote occupational justice in residential care.

Direct health and residential care costs of people living with dementia in Australian residential aged care.

ObjectivesThis analysis estimates the whole‐of‐system direct costs for people living with dementia in residential care by using a broad health and social care provision perspective and compares it to people without dementia living in residential care.MethodsData were collected from 541 individuals living permanently in 17 care facilities across Australia. The annual cost of health and residential care was determined by using individual resource use data and reported by the dementia status of the individuals.ResultsThe average annual whole‐of‐system cost for people living with dementia in residential care was approximately AU$88 000 (US$ 67 100) per person in 2016. The cost of residential care constituted 93% of the total costs. The direct health care costs were comprised mainly of hospital admissions (48%), pharmaceuticals (31%) and out‐of‐hospital attendances (15%). While total costs were not significantly different between those with and without dementia, the cost of residential care was significantly higher and the cost of health care was significantly lower for people living with dementia.ConclusionThis study provides the first estimate of the whole‐of‐system costs of providing health and residential care for people living with dementia in residential aged care in Australia using individual level health and social care data. This predominantly bottom‐up cost estimate indicates the high cost associated with caring for people with dementia living permanently in residential care, which is underestimated when limited cost perspectives or top‐down, population costing approaches are taken.

Pleasure and Dementia

What can pleasure in the nursing home teach us about dementia and subjectivity? In this article I seek to challenge the assumption that the ‘fourth age’ involves the loss of subjectivity. In presenting dementia as a single pathway towards loss and decline, alternative pathways that provide more hopeful imaginaries become obscured. Drawing on ethnographic fieldwork in residential dementia care, I show how care professionals craft conditions that invite residents to take pleasure in, for example, dancing and bathing, and thus to become what I call ‘appreciating subjects’. Although residents do not craft these conditions themselves, they are active in accepting the invitations offered and enacting their appreciations. I argue that pleasure is a relational achievement, one that is contagious for those who let themselves be affected.

Staff awareness of food and fluid care needs for older people with dementia in residential care: A qualitative study.

To examine awareness of aged care home staff regarding daily food and fluid care needs of older people with dementia. Older people in residential care frequently are malnourished, and many have dementia. Staff knowledge of the food and fluid needs of people with dementia is limited. Qualitative research on this topic is scarce but can provide insight into how nutrition and hydration care may be improved. Qualitative, interview-based study. Eleven staff in a range of positions at one care home were interviewed regarding their perceptions of current and potential food/fluid care practices. Transcripts were coded and analysed thematically. Key food and fluid issues reported by these staff members were weight loss and malnutrition, chewing and swallowing difficulties (dysphagia), and inadequate hydration. Staff identified a number of current care practices that they felt to be effective in facilitating older people's food and fluid intake, including responsiveness to their needs. Staff suggestions to facilitate food and fluid intake centred on improved composition and timing of meals, enhanced physical and social eating environment, and increased hydration opportunities. Staff commented on factors that may prevent changes to care practices, particularly the part-time workforce, and proposed changes to overcome such barriers. Staff were aware of key food and fluid issues experienced by the older people in their care and of a range of beneficial care practices, but lacked knowledge of many promising care practices and/or how to implement such practices. Staff need to be supported to build on their existing knowledge around effective food and fluid care practices. The numerous ideas staff expressed for changing care practices can be leveraged by facilitating staff networking to work and learn together to implement evidence-based change.

Participatory arts programs in residential dementia care: Playing with language differences

This article examines connections between language, identity, and cultural difference in the context of participatory arts in residential dementia care. Specifically, it looks at how language differences become instruments for the language play that characterizes the participatory arts programs, TimeSlips and the Alzheimer’s Poetry Project. These are two approaches that are predominantly spoken-word driven. Although people living with dementia experience cognitive decline that affects language, they are linguistic agents capable of participating in ongoing negotiation processes of connection, belonging, and in- and exclusion through language use. The analysis of two ethnographic vignettes, based on extensive fieldwork in the closed wards of two Dutch nursing homes, illustrates how TimeSlips and the Alzheimer’s Poetry Project support them in this agency. The theoretical framework of the analysis consists of literature on the linguistic agency of people living with dementia, the notions of the homo ludens (or man the player) and ludic language, as well as linguistic strategies of belonging in relation to place.

INFORMATION AND COMMUNICATIONS TECHNOLOGY IN DEMENTIA CARE: ACCEPTANCE AMONG PROFESSIONAL CAREGIVERS

AbstractWhen it comes to dealing with symptoms associated with dementia, a number of studies have established the effectiveness of psychosocial interventions. However, in view of limited financial and human resources, implementing effective interventions in daily practice can be a major challenge for care providers. Recently, there has been a growing interest in the use of Information and Communication Technologies (ICTs) for supporting psychosocial interventions in nursing home settings. ICTs are cost-effective and widely available, and using them could potentially ease the burden of dementia care delivery. Therefore, in order to assess acceptance and attitudes of professional caregivers regarding ICTs in dementia care, a sample of N = 205 professional caregivers (M = 38,81 yrs; 70% female) from 10 residential care facilities located in Berlin completed a standardized questionnaire (TA-EG) on factors associated with technology use and acceptance. Additionally, 11 semi-structured interviews were conducted. Results showed that older and female caregivers, respectively, reported less Competence (z = -4.21, p < .01 and z = -4.44, p < .01, resp.) and Enthusiasm (z = -2.38, p < .05 and z = -4.01, p < .01, resp.) regarding the use of technology in their work environment. Furthermore, qualitative content analysis of the interview transcripts revealed both factors promoting the use of ICTs in residential dementia care, and potential barriers. Important recommendations for the development of ICT-based interventions in dementia care will be reported and general implications for their design and successful adoption will be discussed.

The effects of spaced retrieval training in improving hyperphagia of people living with dementia in residential settings.

To investigate the effectiveness of spaced retrieval for improving hyperphagia in patients with dementia in residential care settings. Although 10-30% of patients with dementia have hyperphagia, most studies have focused on eating difficulties. Only a few studies have focused on hyperphagia. Various memory problems cause hyperphagia in patients with dementia. Spaced retrieval, a cognitive technique for information learning, can be used as a training method to improve memory loss. Recent studies showed that patients who received the training successfully memorised information learned in the training and correctly applied it to their daily lives. Single-blind experiments were performed. The 97 subjects with dementia were recruited from seven institutions. All research participants were stratified into three groups according to cognitive impairment severity and Hyperphagic Behavior Scale scores and then randomly assigned to the experimental and control groups. The experimental group received a six-week one-by-one spaced retrieval training for hyperphagia behaviour. The control group received routine care. After the intervention, the frequency and severity of hyperphagia in the patients with dementia, and food intake were significantly lower in the experimental group than in the control group. However, body mass index did not significantly differ. Our results suggest that the spaced retrieval training could decrease the frequency and severity of hyperphagia in patients with dementia. The content of this training programme is consistent with the normal manner of eating in daily life and is easy for patients to understand and perform. Therefore, it can be applied in residents' daily lives. This study confirms the efficacy of the spaced retrieval training protocol for hyperphagia in patients with dementia. In future studies, the follow-up duration can be increased to determine the long-term effectiveness of the intervention.
