Research to inspire new ideas and promote the sustainable development of dementia care

JCCPA is at the forefront of promoting advanced development for dementia care. We believe that resources and research must be applied to understand the effectiveness of different care solutions and to support a sustained improvement in services in step with the needs of those with dementia. JCCPA’s research team applies its rich experience to conduct studies on dementia, with professionalism and focus, to achieve the goal of discovering innovative care models that can be implemented across industry based on forward-looking research results.

 

Since 2005, JCCPA has completed more than 30 surveys and research studies, exploring diverse topics such as: public misconceptions about dementia; relieving stress for dementia services’ frontline workers; the benefits of minimal constraints on people with dementia; how to avoid dementia patients living in the community getting lost; the efficacy of day care services for people with dementia; the efficacy of cognitive training, psychological education support by phone, acupuncture and others. The research findings supported the argument for promoting quality care services for people with dementia and shaped the future direction of service development.

Current Research

To facilitate people with dementia to receive training at home, JCCPA launches a 24-session online training program, aiming to delay the deterioration of cognitive function, and enhance life satisfaction and daily functioning for people with dementia. Pre- and post-program assessments will be conducted to evaluate the cognitive functioning, mental well-being, social functioning of people with dementia, and impact of supporting people with dementia.

JCCPA launches dementia screening and post-diagnostic support programme to support suspected with dementia and care partners. An evaluation is being conducted to measure the effectiveness of the programme in enhancing the psychological wellbeing of people with dementia and care partners. Participants will be assessed before and after the programme on the psychological wellbeing and cognitive functioning of people with dementia.

Younger onset dementia (people with dementia aged 65 or below) and their care partners demonstrate differences in family, work, financial, and clinical aspects compared to their older counterparts, yet there are inadequate support services. JCCPA has launched the first pilot project in Hong Kong to support people suspected or diagnosed with younger onset dementia and their care partners. An evaluation is being conducted to measure the effectiveness of the project in improving the psychological well-being of people with younger onset dementia and care partners, as well as alleviating the impact of supporting people with younger onset dementia. The evaluation targets two hundred people with younger onset dementia and their care partners, who will be assessed at baseline, project discharge, 3 months, and 6 months after the project. The assessment will gather data on psychological well-being, cognitive functioning, mobility, the impact of supporting people with younger onset dementia, and the effectiveness of the project.

JCCPA initiates the Jockey Club Caring Communities for Dementia Campaign in collaboration with Saint James’ Settlement and Hong Kong University of Science and Technology with the aim to assist in finding people with dementia who get lost using the Bluetooth crowd-sourcing technology and promote the concept of dementia-friendly community through public education. The evaluation of the campaign focuses on two areas, firstly, to examine the effectiveness of the technology in lowering anxiety of care partners towards getting lost, secondly, to investigate if the public education could enhance knowledge of dementia and promote positive attitude towards dementia in the general public. The primary care partners of people with dementia using the Bluetooth crowd-sourcing technology who participate in our study would complete a structured questionnaire when beginning to use the technology, half year, and one year after the usage. The questionnaire measures the anxiety of care partners when people with dementia are getting lost, details of the getting lost episode of care recipients before and during the technology usage, and the technology’s usability. Attendees in public education talks will be invited to complete a questionnaire to measure the change of knowledge and attitude on dementia and motivation to help elderly with dementia who get lost after they attend the public education programmes.

Research shows that unfamiliar and noisy environment and use of restraint during hospitalization may result in the confusion and decondition of people with dementia. Family care partners may find it difficult to manage these acute changes incurred from hospital stay, resulting in the care recipients being transferred to nursing home after hospital discharge. Funded by The Hong Kong Club Charities Trust, JCCPA launches a 12-week post discharge service model to facilitate the rehabilitation and long-term ageing in place of people with dementia discharged from hospitals. An evaluation is conducted on measuring the effectiveness of the programme on improving the functional status of people with dementia and psychological wellbeing of care partners. Two hundred people with dementia discharged from hospitals and their care partners are targeted in this evaluation and are assessed at baseline, programme discharge, 3 months and 6 months after the programme on mobility, cognitive functioning, nutritional level, and mental wellbeing of care recipients, impact of supporting people with dementia, and living status after the programme. In collaboration with the Nethersole School of Nursing of CUHK, cost-effectiveness and social impact of the programme is also being evaluated.

Care partners may encounter multiple crises when supporting people with dementia, e.g., care partners do not know how to effectively handle the symptoms of dementia, or decide whether their relative need to go to a nursing home, these crises cause both physical and emotional stress to care partners. As such, JCCPA has implemented a consultation service provided by a healthcare professional to assist care partners in supporting people with dementia.

The evaluation study of this intervention showed that care partners reported emotional stress from the uncertainty of the diagnosis and progression of dementia as well as from the deteriorating health of people with dementia. Notably, many care partners did not have community support. To address care partners’ concerns, the healthcare professional offered information about dementia and future care planning, and practical and customised solutions in supporting people with dementia.

Care partners were satisfied with the consultation service. The service facilitated care partners to arrange a diagnostic consultation for their family members and led care partners to feel more motivated and knowledgeable to seek community support after the consultation.

Funded by The Hong Kong Club Charities Trust, JCCPA launches a variety of training and support to both the care partners and to local citizens on helping people with dementia in neighbourhood, and city-wide public education to facilitate the general public to understand more about dementia and how everyone in the community can do to help people with dementia in daily lives. The evaluation of this community project will focus on the change of behavior, attitude, condition, and knowledge of the participants after attending our training and programmes, and their satisfaction towards this project.

Research Report

To facilitate the service provision of staff of the elderly settings to people with dementia, JCCPA initiated an outreach training offered by our training consultant to the staff in dementia and elderly units. The training included the knowledge and caring techniques on dementia in the actual working context, workplace environmental design assessment and suggestion, etc. The outcome measures for the evaluation of the staff training include knowledge on dementia, attitude and feeling on dementia and dementia care, dementia care competence, and satisfaction on programme. The staff attending the training self-completed the assessment at two time-points: before they attend the training, and when they complete the training. In addition, the center in-charges were invited to provide their views on how the training brings changes to the dementia care service provision of their units, and their satisfaction on the programme. After the training, staff showed significant improvement in knowledge of dementia and self-efficacy in caring for people with dementia. Staff were more likely to perceive their attitude and feelings about dementia care as more positive. The center in-charges observed positive changes within the organization following the training. Both staff and center in-charges expressed satisfaction with the programme.
In Hong Kong, the prevalence of restraints in long-term care institutions is high compared to other places. Restraint is usually a preferred option of staff to control residents, and people with dementia are more likely to be restrained than other residents. Studies have identified a range of negative physiological and psychological outcomes associated with the use of restraint, including strangulation, fall, anger, and feeling of humiliation. JCCPA attempted to establish a protocol to promote restraint reduction in local settings by introducing a multi-disciplinary restraint reduction programme in two residential care homes. Before and after the restraint reduction programme, staff self-completed questionnaires about their usage, knowledge, and attitude on restraint, and their competency in dementia care. In addition, the changes in physical restraint and fall of the elder service users throughout the programme were recorded to examine how the programme would help on reducing physical restraint. Restraint use significantly decreased by 30.9% after 12 months of the program.

Services of day care centers for the elderly have been suspended from late January 2020 due to the outbreak of COVID-19. JCCPA initiated a study to investigate how the suspension of day care service influenced the users with dementia and their care partners. People with dementia of two day care centers, JCCPA and Jockey Club CADENZA Hub, who had taken leave during the COVID-19 pandemic and their care partners were recruited to participate in this research. The cognition, psychological well-being and physical mobility of users, and the impact of supporting people with dementia were collected in three time points: Latest assessment record before service suspension, when users resume the service, and three months after the resumption.
iSupport for Dementia (iSupport) is an online education and skill training programme for informal carers developed by the World Health Organization (WHO). It includes five learning modules: (1) general information about dementia; (2) information related to being a carer; (3) self-care; (4) providing care for the person with dementia; and (5) addressing symptoms of dementia. JCCPA collaborates with Flinders University, College of Nursing & Health Sciences to conduct a study in Hong Kong with an aim to (1) investigate the opinions of family carers and care workers about the ease of access the iSupport, user-friendly level and potential problems when they use the iSupport, and (2) investigate the effects of iSupport for family carers. In Phase 1 of the study, we conducted online focus groups to find out the views of family carers and care workers on the revision and implementation of the generic web-based Chinese iSupport for Dementia program.

There is a widespread concern about whether pre-licensure health and social care professionals receive adequate training before serving the population with dementia. This study assessed the knowledge of dementia among undergraduates in health and social care in Hong Kong. The results showed that the students were generally poor in knowledge of dementia. We suggest that adequate knowledge of dementia could be achieved among future professionals by strengthening their self-efficacy in dementia care and increasing the hours of dementia education.

Difficulties in finding one's way, disorientation and getting lost in the community are symptoms of dementia. Phone interviews were conducted with care partners of persons aged 60 to 85 with suspected or diagnosed dementia. Results showed that the rate of getting lost exceeded 30% among elderly people with dementia. A higher risk of getting lost occurred among people with greater cognitive decline but maintained mobility. The experience of people getting lost had brought significant distress to more than 40% of the families involved.

This research focused on concurrent cognitive training and its effects in memory training. Findings suggested that older persons without concurrent cognitive stimulation were able to benefit from memory training in the form of improved initiation and memory functioning. On the other hand, regular concurrent cognitive training leveled off the effect of memory exercises.

Although animal-assisted therapy is a popular non-drug treatment in changed behaviors, empirical data is scarce. As such, we conducted a study to evaluate the therapeutic effect of animal-assisted therapy on older people with dementia. After eight to 12 therapy sessions, participants showed higher levels of activity, higher frequency of pleasant emotions and social interactions. In line with previous studies, our findings suggest that animal-assisted therapy may be useful in alleviating changed behaviors among people with dementia.
This study explored the effect of drama therapy on individuals with early stage dementia in alleviating emotional wellbeing and facilitating acceptance. A 10-session drama program was provided to people with dementia at the JCCPA. No significant change in their self-efficacy score was found.
Funded by the Knowledge Transfer Project Fund of CUHK, JCCPA developed a chronic disease self-management program for people with mild neurocognitive disorder (MNCD) to facilitate them to delay further deterioration by helping them better manage their lives physically, psychologically, and socially. A quasi-experimental study was conducted to evaluate the effectiveness of this intervention on enhancing the cognitive functioning, mental-welling, and perceived social support. 13 centers with N=141 elderly with cognitive impairment participated in this study, and assessment were taken at three time-points: baseline, upon completion of intervention, and one year after intervention. The findings of pretest-posttest comparison showed that participants had improved cognitive functioning after the intervention.
During the outbreak of the COVID-19 pandemic, the Social Welfare Department of HKSAR suspended services of day-care centres for older adults as an infection control measure in early 2020. In this time, it was likely that care partners were the only source of care to the older adults. JCCPA investigated the impact of day-care service cessation on the caring experience of care partners of people with dementia. In collaboration with ten day-care centres in Hong Kong, N=152 care partners completed our survey through phone interview or self-completion. Our findings revealed that care partners of people with dementia experienced increased impact of supporting people with dementia during day-care service cessation. Impact of supporting people with dementia was likely to be greater when the care partners were older, when the people with dementia experienced greater emotional or communication issues, or when the care partners spent more time with the people with dementia. More than one-third of the participants preferred day-care services to continue during the pandemic so as to prevent further deterioration of people with dementia’ mobility, cognition, and mood, as well as provide respite for care partners. Therefore, while infection control measures are important, interventions to improve the wellbeing of and support people with dementia and their care partners should also be prioritised.

The study evaluated the benefits of using toys and games onto various stakeholders including day care or residential service users with dementia, care partners, and staff (paid and voluntary). JCCPA conducted staff surveys and qualitative interviews to dyads of care partners, people with dementia and volunteers. Our findings revealed that people with dementia and care partners were satisfied with the programme. People with dementia’ social engagement, self-esteem, and sense of competency increased when they independently completed the games. Care partners reported improvement in people with dementia’ physical and cognitive functioning and emotional wellbeing, and that the programme offered respite and reduced impact of supporting people with dementia. Staff viewed the programme favourably as the programme strengthened staff’s dementia caring skills. Overall, this service model was feasible, acceptable, and effective to provide quality dementia care to people with dementia, respite to care partners, and professional development to staff. We suggest that (1) NGOs should regularise this intervention and (2) care partners should encourage their family members with dementia to participate in this programme.
Literature has shown that calligraphy is beneficial to cognitive function and quality of life in the general public and in clinical populations. In this study, we found that regular calligraphy practice preserves cognitive ability (e.g. orientation) among older adults.

Research shows that the physical and emotional burden of dementia caring may initiate grief of the care partners. With the support of the Knowledge Transfer Fund of the Chinese University of Hong Kong (CUHK), the Department of Medicine & Therapeutics of CUHK, the Department of Social Work of CUHK, and the Jockey Club Centre for Positive Ageing conducted a research about the "grief and loss" experienced by the care partners of people with dementia to facilitate better grief detection and management.

Self-constructed questions were used to assess dementia knowledge and treatment seeking tendency of Hong Kong residents. Findings showed that respondents had a variety of misconceptions about dementia and its symptoms. Respondents who had more misconceptions about dementia were less willing to seek for treatment options. We suggested to strengthen fellow citizen's understanding of dementia by organizing public educational programs. The result would assist departments and organizations concerned in determining their course of action.

Leaving decisions to family members is common among elderly people with dementia. However, surrogate decision makers often lack the necessary knowledge to decide on life-sustaining treatment (LST) options for patient. This study examined attitudes toward LST in care partners. They displayed poor knowledge about LST. Most were reluctant to forgo treatments. More dialogue and education are needed about end-of-life care in the early phase of dementia

This study aimed to determine the prevalence of restraint use in hospital medical wards in Hong Kong. The results showed that more than two-thirds of nursing staff reported using restraint or force in the past three months. To reduce restraint use in patient care, steps must be taken to reduce burnout and to foster social support among nurses.

With the ageing population, day care services are in great demand in Hong Kong. A survey was conducted to investigate the usage pattern of elderly day care centers for the elderly by demented clients and the difficulties perceived by staff in caring for them. 55 of the 59 in-charge persons of government day care centers in Hong Kong filled out a self-administered questionnaire about the composition of day care users and the difficulties perceived by staff in caring for demented clients. 98.0% of the respondents reported that demented clients with good mobility were very or quite difficult to take care of. The main perceived hindrances were manpower shortage (54.5%) and insufficient space (20.0%).

Day care services are reported to be effective in maintaining the cognitive ability of people with dementia and in improving their behavioral and psychological symptoms. In this study, JCCPA further examined the role of day care services in reducing caregivers' stress and in facilitating nutrition level and quality of life. 27 men and 63 women with dementia newly admitted to JCCPA were assessed at baseline, month 6, and month 12. The caregivers' stress decreased significantly at month 12. The cognitive function and the quality of life were maintained at months 6 and 12. The nutrition level improved significantly at month 6. However, there was a significant deterioration in the score for daily living ability and the score for mobility at month 12. The score for behavioral and psychological problems also increased significantly at month 6.

This study evaluated the effectiveness of the Active Mind cognitive-training program in improving the cognitive function and quality of life (QoL) for local community-dwelling older adults. A total of 200 subjects were recruited from 20 different district elderly community centers, which were randomly assigned into either the intervention group or control group. The intervention group underwent eight 1-hour sessions of cognitive training, while the control group was included in the usual group activities provided by the centers. A total of 176 subjects completed the study. The intervention group showed greater improvement in the cognitive function and QoL. Subjects with lower education level were associated with better cognitive response to the cognitive-training program.

The job satisfaction of live-in foreign domestic helpers (FDHs) may influence their caring motivation and the quality of care they provide, which may in turn affect the health status of care recipients. This study identified the factors affecting job satisfaction of FDHs caring for people with dementia in Hong Kong, focusing especially on the role of FDHs' adaptation status, job self-efficacy and people with dementia' situation. A total of 152 FDHs taking care of people with dementia were recruited from 6 day care centers where they attended with people with dementia. The results showed that longer stay in Hong Kong, better fluency in Cantonese (local dialect), greater satisfaction in living conditions, higher self-efficacy in supporting people with dementia, and less changed behavior of people with dementia were independently associated with stronger job satisfaction in FDHs looking after people with dementia. On the basis of these findings, we would suggest that employers should consider helpers who have been in Hong Kong for a longer period of time and speak fluent Cantonese, and have previous experience of taking care of people with dementia. In addition, FDHs caring for people with dementia may benefit from carer training which improves their self-efficacy in dementia care.

Older adults with dementia are often afflicted with sleep problems. Recent studies have suggested that acupuncture may be a feasible alternative to traditional sleep medicine for treating sleep disturbance. This study investigated the effectiveness of acupuncture on sleep quality of older adults with dementia. Nineteen people with dementia were followed through a control period and an acupuncture treatment period, each lasting 6 weeks. The subjects gained significantly more resting time and total sleep time in the treatment period than in the control period. A non-significant trend for improvement in sleep efficiency was observed.

Many care partners of persons with dementia are unable to participate in community center-based care partner support services because of logistical constraints. Due to the constraints, JCCPA offered a telephone-delivered psychoeducational intervention for care partners to alleviate impact of supporting people with dementia and enhancing self-efficacy in caring. In a single-blinded randomized controlled trial, 38 care partners were randomly allocated into an intervention group or a control group. The intervention group received psycho-education from a registered social worker over the phone for 12 sessions. Care partners in the control group were given a DVD containing educational information about dementia care. The effect of supporting people with dementia in the intervention group reduced significantly compared with care partners in the control group. Care partners in the intervention group also reported significantly more gain in self-efficacy in obtaining respite than the control group.

This study examined the short-term and long-term effects of a cognitive training program in enhancing cognitive function of older people with subjective memory complaints. In the trial, 223 older participants were randomly assigned to either the intervention group or the health related educational control group. The intervention group received cognitive training led by an occupational therapist once a week for 12 weeks, while the control group attended a series of health-related educational lectures in small groups led by the same occupational therapist. Results indicated that cognitive training was effective in enhancing the overall cognitive function of less educated older adults. The positive effect was durable for at least nine months in conceptualization and memory.

JCCPA was commissioned by Hong Kong Lutheran Social Service (HKLSS) to conduct a randomized controlled trial that evaluated the effectiveness of toy intervention on people with mild cognitive impairment (MCI) on enhancing their cognition and mental wellbeing. 119 people with MCI, recruited from four HKLSS centers, participated in a 12-week research. Both intervention and control groups demonstrated improvement in psychological wellbeing, overall quality of life, and cognitive functioning after participating in intervention or control activities. The intervention group showed statistically significant improvement in psychological wellbeing and overall quality of life; while participants from the intervention group who were more cognitively impaired yielded statistically significant improvement in cognitive functioning.
In both acute care and residential care settings, physical restraints are frequently used in the management of older people. Building on the reported negative outcomes of physical restraint use, JCCPA examined the effects of the nursing practice on patients' length of stay (LOS) in hospitals. Medical records of 910 older patients aged 60 years or above and admitted to one Hong Kong public hospital in 2007 were randomly selected and recorded during July to September 2011. The results indicated that older patients' general health status, physical, and cognitive function were important factors affecting their LOS. However, independent of these factors, the physical restraint use was still significantly predictive of longer LOS.

Previous research conducted by JCCPA has suggested that an online support system lowered the impact of supporting people with dementia. This study further evaluated the effectiveness of the online intervention for care partners in improving their self-efficacy in handling changed behavior, and their emotional well-being. A total of 36 care partners of people with dementia participated in a 9-week online intervention based on the cognitive behavioral therapy model. The severity of changed behavior of people with dementia and changed behavior-related distress in care partners showed a statistically significant reduction after the intervention. Subgroup analysis showed self-efficacy in controlling upsetting thoughts significantly improved in people with dementia at moderate to severe stages.

JCCPA was commissioned by the Hong Chi Association to evaluate the effectiveness of life story work (LSW) on enhancing mood, socialization and quality of life for ageing people with mild to moderate levels of intellectual disabilities. Research findings from 60 older adults aged 50 to 90 and with mild to moderate intellectual disabilities indicated that LSW was useful for elderly people with intellectual disabilities by enhancing their quality of life and preventing deterioration in mood. It also helped improve participants' social skills. Through the activity, staff and care partners were benefited by seeing their clients or family members with intellectual disabilities as unique individuals.

This study evaluated the effectiveness of the training offered to the staff about dementia care on improving their knowledge of dementia and sense of competence of dementia care. The findings showed that the trainees had improved knowledge on dementia, and the professional staff had improved competency towards dementia care after the training. The trainees are in general satisfied with the training.
A randomized controlled trial with a waitlist control design was conducted to evaluate the effectiveness of a game intervention on enhancing the quality of life and cognitive functioning of the elderly with dementia who join day care centres. Assessment was taken at baseline, upon completion of intervention, and three months post-intervention. N=83 subjects were included in the analysis. The quality of life and cognitive functioning of intervention group increased significantly after intervention, while those of control group yielded an insignificant improvement of mean score. The difference of the change of quality of life and cognitive functioning between intervention group and control group was not significant. As for the evaluation of public education, over 80% of subjects indicated that they had good knowledge and positive attitude towards dementia after the education talks.
This study examined the effectiveness of a game porgramme and a music porgramme offered by secondary school students to people with dementia. N=36 elderly with dementia joining the game porgramme, N=8 elderly with dementia joining the music porgramme, and N=25 secondary school students leading these porgrammes participated in this evaluation. The findings showed that the elderly were satisfied with the porgrammes, the elderly participating of the game porgramme commented that they enjoyed playing games with younger generation and activity with young generation would attract them to go to the elderly centres. The participants of the music porgrammes also enjoyed playing with the younger generation and they felt happy joining the porgrammes. The secondary school students were satisfied with the porgrammes, and they recognized the strengths of the elderly and felt more confident communicating with the elderly after the porgrammes. They were also more willing to help the elderly and participating in activities with the elderly after these porgrammes.
JCCPA launched a training programme for the domestic helpers to enhance their knowledge about dementia, and their skills in caring for people with dementia. N=297 domestic helpers self-completed a questionnaire after the training to evaluate the effectiveness of the training. 99% of the participants commented that the training enhanced their knowledge about dementia, and improved their understanding towards the needs of people with dementia as well as confidence about communicating with people with dementia. 98% of the participants felt more confident offering help to people with dementia after the training.
JCCPA collaborated with the Dementia Services Development Centre of the University of Stirling to localize its Best Practice Training Dementia Care ("Best Practice Training") to Hong Kong workers. Different from the traditional classroom learning, the Best Practice Training adopts the "train-the-trainer" model, in which the professional staff ("facilitators") in elderly settings attended a three-day workshop, then the facilitators taught their frontline colleagues ("learners") during the 12 two-hour coaching sessions. The evaluation of the programme measured the improvement of staff on providing dementia care after the programme. Before the programme and 12-month after the enrolment, all the participants completed questionnaires measuring the following variables: Knowledge (learners only), attitude, and perceived competence (learners only) in dementia care, and job satisfaction. Fifty reflective writings were randomly selected to validate the results of the questionnaires. In total, 1,264 participants, including 195 facilitators and 1,069 learners, from 70 elderly settings were included. Results showed that participants improved significantly in all variables after the training.

Dementia has an effect on the entire family system because family members are usually the main carers of people with dementia, and the caring tasks are ever-changing to accommodate the needs of different stages of dementia. However, the individual model of dementia continues to be the dominant theoretical perspective in dementia care. This qualitative study explored themes that described families taking care of elderly relatives with dementia in Chinese society. Five themes were drawn from 20 family therapy sessions which elevated our understanding of family context in the provision of care to an elderly person with dementia: positive affection as coping strategies, power and control in the caring relationship, adult children's involvement in caring, sibling rivalry, and intergenerational conflicts.

Coconut oil has a prominent position in the food and medical tradition, especially in places where palms are cultivated, such as South America and Southeast Asia. In recent decades, however, health concerns about the risk saturated fats have on cardiovascular diseases, along with the high amount of saturated fats in coconut oil, have made many hesitate to consume the oil. This review examines the existing evidence on the nutritional value of coconut oil, in particular the effects it has on the risk management of Alzheimer's disease. Continue to full text
Wandering is a behaviour that may be exhibited by some people with dementia. There may be various factors associated with wandering, such as cognitive decline, unmet needs of people with dementia, or the environment. Wandering may put people with dementia at higher risk of getting lost, while the use of assistive technology and a dementia-friendly community may facilitate people with dementia to live in the community more safely and independently.

Maintaining good psychological health in elderly is one of the important factors in reducing the risk of dementia. This article will detail the association between depression, anxiety and cognitive function, and the way mindfulness activities can assist participants to enhance psychological flexibility. By encouraging self-compassion and resilience, older adults might be more capable of dealing with ongoing challenges in life, as well as reducing the risk of cognitive decline. Continue to full text
Family caregivers of people with dementia may experience grief in advance of the death of their care recipients, which is termed anticipatory grief. It involves stages of coping from mourning to psychosocial reorganization incurred by the anticipation of the loss of a loved one in the near future. For dementia caregivers, in particular, this sense of loss can entail the losses of companionship, personal freedom, control, well-being, and personhood for the care recipient. The grieving process is often characterized by anticipation and ambiguity about the future as well as a wide range of negative emotions, such as anger, frustration and guilt. Studies from the western countries estimated that around 47% to 71% of the caregivers experience anticipatory grief, and close to 10% may be at risk of severe grief reactions needing professional help.

The concept of dementia specialized care unit was developed in America in the seventies, in the aim to provide better care to people with dementia. There are no concrete standards on how a dementia specialized care unit should equip itself, while the units claim measures specifically designed for people with dementia such as physical design, program, staff training etc. Previous studies comparing benefits of specialized care units on people with dementia versus integrated care setting resulted in discrepancies in benefits or effectiveness, while the major trend of published studies skew towards confirming that specialized care units benefit some cohorts of people with dementia in some areas. This literature review documented some previous studies in the recent decade examining the advantages of specialized care unit and added views on what an integrated care setting has been investigated to help people with dementia.

A review on the subjective needs of PWD revealed that people at the early to moderate stage of dementia valued well-being and coping needs over functional, instrumental supports. What they regarded as their top concerns were social supports and ways to compensate for their cognitive deficits that would help ease their grief and frustrations. A study investigating the needs of institutionalized elderly PWD found that environmental and physical needs of the old people were usually taken care of, yet mental health care and social needs were usually unmet. The study reported that PWD, in general, lacked stimulating daytime activities, that their depression and anxiety were often left untreated, and that many revealed to have no company. The service gap, therefore, mirrored the claim made by O'Connor, Ames, Gardner, King, which demonstrated that human attention and enjoyable interaction in some studies (while treated as control activities) yielded comparable results as interventions such as validation therapy and progressive muscle relaxation training, providing evidence on the notion that intervention to people with dementia should take human attention or social interaction into consideration.

Caregiving is a stressful experience, but when it comes to dementia caregiving, the stress could become more intense. Research has shown that caregivers of people with dementia engage in a greater intensity of work and face more problems. The high caregiving hours and degree of daily activity assistance are reported to associate directly with stress. The effect of chronic stress extends beyond psychology to physical wellbeing. Studies have related dementia caregiving to heart disease risk, wound healing performance, and other immune functions. For example, a study comparing 49 spousal caregivers of persons with dementia and 67 healthy non-caregivers of the same age reported a lower cell-mediated immunity and an elevated level of salivary cortisol, a stress indicator, among dementia caregivers.

With the notion that "if exercise could be packed into a pill, it would be the single most widely prescribed and beneficial medicine in the nation", it has long been proposed that an active lifestyle is the medicine for frail adults. This issue's Dementia Research in Focus outlines the therapeutic effects of physical exercise and the importance to engage in a long term active lifestyle. Continue to full text
Although dementia has no known cure at the moment, it is suggested that preventable causes account for 1/3 to 1/2 of the disease cases. This research review will focus on the risk factors of dementia and subsequent lifestyle changes. Continue to full text
Research shows that trans fat is associated with cardiovascular diseases and diabetes, it may also heighten the risk of cognitive damage and dementia. Both local and international governmental bodies have issued guidelines about the consumption of trans fat. As a continuation of the preventive measures on dementia, the Research In-focus of this quarter further illustrates the effects dietary habit has on cognition. Continue to full text
Currently, dementia affects around 9% of Hong Kong elderly aged over 70. It is estimated that in 2036, there will be 230,000 community-dwelling senior citizens with dementia. Studying the prevalence as well as the risk factors of dementia would help understand what we can do to alleviate the demented population. Continue to full text
Recent studies have introduced the MIND diet to promote brain health. Moderating two established dietary patterns based on current evidence of large-scale observational studies, researchers believe that the MIND diet might point to a more accurate eating guideline to slower age-related cognitive decline.

Restraints may come in the form of physical restraint or chemical restraint. Despite the lack of evidence of restraint use as an effective therapeutic measure, restraint use is prevalent among long term care facilities in Hong Kong. Dementia and cognitive impairment may be associated with increased likelihood of being restrained. Academic studies have suggested various potential adverse outcomes of restraint use such as fall, poorer cognitive outcomes, increased dependence in walking and death. Restraint reduction program is proven beneficial to the hospitalized elderly with cognitive impairment; in long term it is suggested to promote restraint reduction in elderly settings in order to provide better elderly care in Hong Kong.

Caregivers of people with dementia (PwD) often find themselves in a difficult position to make proxy decisions for the care recipients if the care recipients have not expressed their care wishes before their cognitive ability declined. The decision making is even harder when there is family disagreement at times of healthcare crises. There is some evidence in dementia-related literature pointing to the effectiveness of ACP in minimizing inappropriate hospital admissions, death of PwD and increased use of hospice. Therefore, to maintain care in accordance with the PwD's wishes, a discussion about future care should be made when the PwD is still in the early stage. Continue to full text
