Effects of Dementia on Outcomes after Cervical Spine Injuries in Elderly Patients: Evaluation of 1512 Cases in a Nationwide Multicenter Study in Japan

We aimed to retrospectively investigate the demographic characteristics and short-term outcomes of traumatic cervical spine injuries in patients with dementia. We enrolled 1512 patients aged ≥ 65 years with traumatic cervical injuries registered in a multicenter study database. Patients were divided into two groups according to the presence of dementia, and 95 patients (6.3%) had dementia. Univariate analysis revealed that the dementia group comprised patients who were older and predominantly female and had lower body mass index, higher modified 5-item frailty index (mFI-5), lower pre-injury activities of daily living (ADLs), and a larger number of comorbidities than patients without dementia. Furthermore, 61 patient pairs were selected through propensity score matching with adjustments for age, sex, pre-injury ADLs, American Spinal Injury Association Impairment Scale score at the time of injury, and the administration of surgical treatment. In the univariate analysis of the matched groups, patients with dementia had significantly lower ADLs at 6 months and a higher incidence of dysphagia up to 6 months than patients without dementia. Kaplan-Meier analysis revealed that patients with dementia had a higher mortality than those without dementia until the last follow-up. Dementia was associated with poor ADLs and higher mortality rates after traumatic cervical spine injuries in elderly patients.

Daily sleep, well-being, and adult day services use among dementia care dyads

OBJECTIVES

The study aimed to describe daily sleep characteristics for dementia care dyads in the context of adult day services (ADS) use and examine the associations with sleep quality and daytime functioning (fatigue, affect, and behavior problems).

METHODS

Caregivers (CG; N = 173) reported daily bedtime, wake time, and sleep quality for themselves and the persons living with dementia (PLWD) across 8 consecutive days (N = 1359), where PLWD attended ADS at least 2 days of the week. On each day, caregivers also reported their own fatigue and affect and PLWD's daytime behavior problems and nighttime sleep problems. Considering the context of ADS use, we compared mean differences in bedtime, wake time, and total time in bed on nights before versus after ADS use. We estimated multilevel models to examine daily sleep-well-being associations.

RESULTS

On nights before an upcoming ADS day, care dyads went to bed and woke up earlier, and spent less time in bed. Further, PLWD had better sleep quality the night before an upcoming ADS day. Using ADS during the day buffered the negative impact of PLWD's sleep problems in the previous night, reducing daytime negative affect for caregivers. For caregivers, using ADS yesterday attenuated the association between shorter than typical time in bed and daytime fatigue; it also attenuated the association between PLWD's nighttime sleep problems and lowered daytime positive affect.

CONCLUSIONS

Regular ADS use may promote earlier sleep timing and protect against the adverse impact of sleep disturbances on daytime functioning for dementia care dyads.

Development and validation of a system for the prediction of challenging behaviors of people with autism spectrum disorder based on a smart wearable shirt: A mixed-methods design

Background

Most people with autism spectrum disorder (ASD) present at least one form of challenging behavior (CB), causing reduced life quality, social interactions, and community-based service inclusion.

Objectives

The current study had two objectives: (1) to assess the differences in physiological reaction to stressful stimuli between adults with and without high-functioning ASD; (2) to develop a system able to predict the incoming occurrence of a challenging behaviors (CBs) in real time and inform the caregiver that a CB is about to occur; (3) to evaluate the acceptability and usefulness of the developed system for users with ASD and their caregivers.

Methods

Comparison between physiological parameters will be conducted by enrolling two groups of 20 participants with and without ASD monitored while watching a relaxing and disturbing video. To understand the variations of the parameters that occur before the CB takes place, 10 participants with ASD who have aggressive or disruptive CBs will be monitored for 7 days. Then, an ML algorithm capable of predicting immediate CB occurrence based on physiological parameter variations is about to be developed. After developing the application-based algorithm, an efficient proof of concept (POC) will be carried out on one participant with ASD and CB. A focus group, including health professionals, will test the POC to identify the strengths and weaknesses of the developed system.

Results

Higher stress level is anticipated in the group of people with ASD looking at the disturbing video than in the typically developed peers. From the obtained data, the developed algorithm is used to predict CBs that are about to occur in the upcoming 1 min. A high level of satisfaction with the proposed technology and useful consideration for further developments are expected to emerge from the focus group.

Activity, Activity Personalization, and Well-Being in Nursing Home Residents With and Without Cognitive Impairment: An Integrative Review

OBJECTIVES

Engagement in personally relevant and pleasant activity is a facet of many theories of well-being. This integrated review and narrative synthesis explored the hypothesis that activity participation improves well-being for nursing home residents.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched MEDLINE, PsycINFO, Academic Search Complete, Psychology and Behavioral Sciences Collection, Embase, and CINAHL for research published between 2006 and 2018. We included peer-reviewed, English-language studies of nursing-home residents, with interventions focused on activities and on well-being or affect outcomes.

RESULTS

After screening, the search yielded 45 studies: 15 reviews of specific activities and 30 empirical articles. We found consistent support for tailored activity interventions and less consistent support for specific or generic activity interventions with the possible exception of music therapy. Research focused on specific activity types had methodological limitations and confounds with activity preferences.

CONCLUSIONS

Participation in activities may improve well-being in residents of nursing homes. Tailored activities are likely to be superior to those provided indiscriminately to all residents.

CLINICAL IMPLICATIONS

Improving quality of life in long-term care should include opportunities to engage in activities; those most effective will be tailored to individuals and no single activity will be effective for everyone.

Individual differences in the temporal relationship between sleep and agitation: a single-subject study in nursing home residents with dementia experiencing sleep disturbance and agitation

OBJECTIVES

Previous studies on the interrelationship between sleep and agitation relied on group-aggregates and so results may not be applicable to individuals. This proof-of-concept study presents the single-subject study design with time series analysis as a method to evaluate the association between sleep and agitation in individual nursing home residents using actigraphy.

METHOD

To record activity, three women and two men (aged 78-89 years) wore the MotionWatch 8© (MW8) for 9 consecutive weeks. Total sleep time and agitation were derived from the MW8 data. We performed time series analysis for each individual separately. To gain insight into the experiences with the actigraphy measurements, care staff filled out an investigator-developed questionnaire on their and participants' MW8 experiences.

RESULTS

A statistically significant temporal association between sleep and agitation was present in three out of five participants. More agitation was followed by more sleep for participant 1, and by less sleep for participant 4. As for participants 3 and 4, more sleep was followed by more agitation. Two-thirds of the care staff members (16/24) were positive about the use of the MW8. Acceptability of the MW8 was mixed: two residents refused to wear the MW8 thus did not participate, one participant initially experienced the MW8 as somewhat unpleasant, while four participants seemed to experience no substantial problems.

CONCLUSION

A single-subject approach with time series analysis can be a valuable tool to gain insight into the temporal relationship between sleep and agitation in individual nursing home residents with dementia experiencing sleep disturbance and agitation.

The Rationale and Design of Behavioral Interventions for Management of Agitation in Dementia in a Multi-Site Clinical Trial

BACKGROUND

Agitation and aggression are common in patients with Alzheimer's disease and related dementias and pose a significant burden on patients, caregivers, and the healthcare systems. Guidelines recommend personalized behavioral interventions as the first-line treatment; however, these interventions are often underutilized. The Standardizing Care for Neuropsychiatric Symptoms and Quality of Life in Dementia (StaN) study (ClinicalTrials.gov Identifier # NCT0367220) is a multisite randomized controlled trial comparing an Integrated Care Pathway, that includes a sequential pharmacological algorithm and structured behavioral interventions, with treatment-as-usual to treat agitation in dementia in long-term care and inpatient settings.

OBJECTIVE

To describe the rationale and design of structured behavioral interventions in the StaN study.

METHODS

Structured behavioral interventions are designed and implemented based on the following considerations: 1) personalization, 2) evidence base, 3) dose and duration, 4) measurement-based care, and 5) environmental factors and feasibility.

RESULTS

The process to design behavioral interventions for each individual starts with a comprehensive assessment, followed by personalized, evidence-based interventions delivered in a standardized manner with ongoing monitoring of global clinical status. Measurement-based care is used to tailor the interventions and to integrate them with pharmacotherapy.

CONCLUSION

Individualized behavioral interventions in patients with dementia may be challenging to design and implement. Here we describe a process to design and implement individualized and structured behavioral interventions in the context of a multisite trial in long-term care and inpatient settings. This process can inform the design of behavioral interventions in future trials and in clinical settings for the treatment of agitation in dementia.

Psychosocial care in dementia in European higher education: Evidence from the SiDECar ("Skills in DEmentia Care") project

In dementia care, psychosocial interventions can increase people's quality of life with dementia and their caregivers. Despite their effectiveness, their translation into practice lacks the desirable systematicity. Systematic educational programs on psychosocial interventions in dementia will improve this translation, as it prepares professionals to face the complexity of dementia care. This study aimed to systematically map out the extent to which higher education programs in Europe include teaching activities about psychosocial care of dementia. We collected quantitative and qualitative data about 303 higher education teaching activities on psychosocial care in dementia across Europe. The analysis revealed that the number of teaching activities focusing on psychosocial care in dementia was relative. Although the results reflected UNESCO indications, the teaching activities on psychosocial care in dementia appeared less systematized than optimal. As world health agencies recommend, international higher education systems should consider more psychosocial care topics because they can prepare professionals to respond timely and effectively to dementia patients and caregivers' needs.

Barriers, motivators and facilitators of physical activity in people with dementia and their family carers in England: dyadic interviews

INTRODUCTION

Physical activity may have a number of physical and mental health benefits for people with dementia and their carers. However, there is limited evidence about factors that influence physical activity participation in these groups. This study therefore looks at the barriers, facilitators and motivators of physical activity in people with dementia, from both the perspective of the person with dementia and their carer.

METHOD

Thirty participants (15 sets of community-dwelling people with dementia and their family carers) were recruited from the South East of England. The participants took part in semi-structured dyadic interviews about their views of physical activity. Interviews were analysed using inductive thematic analysis at an individual level and comparisons were made between the groups.

RESULTS

Common motivator themes across persons with dementia and family carers were emotional and physical wellbeing, and social connectedness. Physical health was seen as a common barrier in both groups. Physical activity in the person with dementia was encouraged and supported by the family carer. For the carer, their caring role, and limited time acted as barriers to their participation.

CONCLUSION

Themes such as social connectedness, positive emotion and health were seen as key motivators to physical activity, which indicate that people with dementia and carers use physical activity as a means to maintain and improve their quality of life. Supporting family members to better facilitate such activities could encourage physical activity in people with dementia.

Non-Pharmacological interventions for the anxiety in patients with dementia. A cross-over randomised controlled trial

BACKGROUND

Behavioural and Psychiatric Symptoms in dementia (BPSD) tend to be a crucial and big problem in dementia. Anxiety several times remains under-diagnosed because it is often considered to be a psychological response to cognitive decline. As only the 10 % of patients were correctly treated, the pharmacological treatment should be well- considered. The aim of this study was to evaluate three non-pharmacological interventions for the treatment of anxiety in dementia.

METHODS

A cross-over randomised controlled trial with 60 participants (different types and stages of dementia) conducted in Greece. The sample was randomly assigned to 6 different groups of 10 participants each. The non-pharmacological interventions that have been evaluated are: a) Music Therapy b) Exercise and c) Aromatherapy & Massage. The measurements that were used are: MMSE, ACE-R, GDS, FRSSD and NPI questionnaire. The interventions lasted 5 days and there was two days off as a wash-out period. There was no drop-out rate.

RESULTS

The study showed that the most effective intervention is Music therapy. The second most effective intervention is Exercise and the third one is Aromatherapy and Massage. In the parenthesis p results indicate that Music Therapy's p is less than 0.05 in comparison with Exercise and Aromatherapy and Massage and therefore the sequence of the interventions does not interfere with the results. (p = <0.05, p = 0.55, accordingly). Caregivers' burden also reduced with MT. In the parenthesis p results indicate Music Therapy's p is less than 0.05 in comparison with the two other interventions and therefore the sequence of the interventions does not interfere with the results, as well (p = <0.05, p = 0.19).

CONCLUSIONS

Our results are in accordance with the current literature. Music Therapy is a promising alternative intervention for the treatment of anxiety in PwD. Music Therapy is an effective non-pharmacological treatment for the reduction of the caregivers' burden, because of the anxiety symptoms in PwD, such as lack of sleep, lack of personal time, unhealthy lifestyle, lack of solutions on what to do with their patients etc. The type of music, the duration of the intervention and the long-term benefits remain unclear. There is a big need of further research with stronger possible evaluation methods.

Effectiveness of Occupational Therapy Interventions to Enhance Occupational Performance for Adults With Alzheimer's Disease and Related Major Neurocognitive Disorders: A Systematic Review

OBJECTIVE

The purpose of this systematic review was to describe the evidence for the effectiveness of interventions designed to establish, modify, and maintain occupations for adults with Alzheimer's disease (AD) and related neurocognitive disorders.

METHOD

Titles and abstracts of 2,597 articles were reviewed, of which 256 were retrieved for full review and 52 met inclusion criteria. U.S. Preventive Services Task Force levels of certainty and grade definitions were used to describe the strength of evidence.

RESULTS

Articles were categorized into five themes: occupation-based, sleep, cognitive, physical exercise, and multicomponent interventions. Strong evidence supports the benefits of occupation-based interventions, physical exercise, and error-reduction learning.

CONCLUSION

Occupational therapy practitioners should integrate daily occupations, physical exercise, and error-reduction techniques into the daily routine of adults with AD to enhance occupational performance and delay functional decline. Future research should focus on establishing consensus on types and dosage of exercise and cognitive interventions.

The Effects of a Multicomponent Dyadic Intervention With Physical Exercise on the Cognitive Functioning of People With Dementia: A Randomized Controlled Trial

The objective was to evaluate the effects of a multicomponent dyadic intervention on the cognitive functioning of people with dementia living at home in a randomized controlled trial. People with dementia and their family caregivers (n = 111) were randomly assigned to 8 home-based sessions including physical exercise and support or a minimal intervention consisting of monthly written information bulletins and monthly phone calls. Memory, executive functioning (EF), and attention were assessed at baseline, and after 3 (postmeasurement) and 6 months (follow-up). Data were analyzed by using generalized estimating equations (GEE). A small, significant effect was found on attention. No effects were found on memory and EF. Finding only a small significant effect might be explained by the ineffectiveness of the intervention, but also by moderate treatment adherence or a lack of room for improvement because half of the people with dementia were already receiving care in a day care facility.

The Diagnosis and Treatment of Behavioral Disorders in Dementia

BACKGROUND

Behavioral disorders such as aggressiveness, agitation, delusions, disinhibition, affect lability, and apathy arise in more than 90% of patients with dementia. Behavioral disorders are a major challenge and the greatest stress factor in everyday life for nursing personnel and for family members caring for the patient.

METHODS

This review is based on relevant publications retrieved by a selective literature search in the PubMed, Cochrane Library, and German S3 guideline databases with the search terms "behavioral disorders," "non-cognitive disorders," and "challenging behavior," in conjunction with "dementia" and "behavioral and psychological symptoms of dementia."

RESULTS

Behavioral disorders regularly accompany dementing illness and have identifiable and treatable somatic and environment-related causes. They should be treated symptomatically, both with non-pharmacological measures and with drugs. Memory therapy (d = 0.47), ergotherapy (d = 0.72), music therapy (d = 0.62), and physical exercise (d = 0.68) are effective, as are antidementia drugs (galantamine: p = 0.04, donepezil: p = 0.01, rivastigmine: p = 0.02, memantine: p = 0.004). Risperidone is the drug of choice to combat agitation and aggressiveness (d = 0.33) as well as dementia and hallucinations (d = 0.5). Citalopram can be recommended for the treatment of depression in patients with dementia (p = 0.05).

CONCLUSION

Because of an improved evidence base, the latest version of the German S3 guideline on the diagnosis and treatment of dementia places greater emphasis on non-pharmacological treatments for behavioral disorders in dementia than it did in the past. The global efficacy of such treatments against behavioral disorders is well documented. Nonetheless, because of the heterogeneity of interventions and varying standards of assessment, the evidence for the utility of certain specific methods in the treatment of specific behavioral disorders is still limited. More research is needed in this area.

Exploring the relationship between community-based physical activity and wellbeing in people with dementia: a qualitative study

This study sought to identify factors which influenced how a group of people with dementia living in their own homes participated in community-based physical activity and explored the effect that exercise groups, dance and walking had on their wellbeing. A broadly ethnographic approach was adopted in which participant observation and interviews were employed. Nineteen people with dementia and seven formal and informal carers were included in the participant observation phase. Eleven people with dementia were interviewed. The analysis and interpretation of data was informed by embodiment and social constructionist theoretical perspectives. Findings suggest that a complex interplay between attitudes and beliefs, retained embodied abilities, and aspects of the physical and social environment influenced how individuals engaged in physical activity and the degree to which they experienced wellbeing as a result. Findings suggest that when certain factors co-exist, physical activity can provide a context within which people with dementia are able to use embodied skills in order to support fragile identities, connect with others and express themselves.

Increased self-efficacy: the experience of high-intensity exercise of nursing home residents with dementia - a qualitative study

Background

There has been increasing interest in the use of non-pharmacological interventions, such as physical exercise, to improve the well-being of nursing home residents with dementia. For reasons regarding disease symptoms, persons with dementia might find it difficult to participate in exercise programs. Therefore, it is important to find ways to successfully promote regular exercise for patients in residential care. Several quantitative studies have established the positive effects of exercise on biopsychosocial factors, such as self-efficacy in older people; however, little is known regarding the qualitative aspects of participating in an exercise program among older people with dementia. From the perspective of residents, we explored the experiences of participating in a high-intensity functional exercise program among nursing home residents with dementia.

Methods

The participants were eight elderly people with mild-to-moderate dementia. We conducted semi-structured interviews one week after they had finished a 10-week supervised high-intensity exercise program. We analyzed the data using an inductive content analysis.

Results

Five overreaching and interrelated themes emerged from the interviews: “Pushing the limits,” “Being invested in,” “Relationships facilitate exercise participation,” “Exercise revives the body, increases independence and improves self-esteem” and “Physical activity is a basic human necessity—use it or lose it!” The results were interpreted in light of Bandura’s self-efficacy theory. The exercise program seemed to improve self-efficacy through several mechanisms. By being involved, “being invested in” and having something expected of them, the participants gained a sense of empowerment in their everyday lives. The importance of social influences related to the exercise instructor and the exercise group was accentuated by the participants.

Conclusions

The nursing home residents had, for the most part, positive experiences with regard to participating in the exercise program. The program seemed to increase their self-efficacy through several mechanisms. The instructor competence emerged as an important facilitating factor. The participants emphasized the importance of physical activity in the nursing home.

Engagement in Instrumental Activities of Daily Living, Social Activities, and Use of Everyday Technology in Older Adults with and without Cognitive Impairment

Introduction:

Little is known about how subtle activity limitations may be manifested and clinically detected in people with mild cognitive impairment, but these people have been found to experience greater challenges with everyday technology use. The aim of this study was to investigate levels and profiles of engagement in activities, and their associations with perceived difficulty in technology use, for people with mild cognitive impairment, and to compare this group to people with Alzheimer's disease and to controls.

Method:

Samples with mild cognitive impairment (n = 37), Alzheimer's disease (n = 37), and controls (n = 44) were included. Based on raw data from the Frenchay Activity Index, a Rasch model was used to generate linear measures. Analysis of variance and differential item functioning were used.

Results:

The analysis yielded a profile of decreased engagement in specific activities even in mild cognitive impairment. The association between activity engagement and difficulty with everyday technology use was stronger in people with mild cognitive impairment and Alzheimer's disease than in controls.

Conclusion:

Taken together, engagement in outdoor activities showed the greatest decrease of all activity types for the group with mild cognitive impairment, suggesting that participation in life outside the home is threatened. The results also suggest that challenges in managing technology are restricting people with cognitive impairment more than they restrict controls.

A longitudinal study of gait function and characteristics of gait disturbance in individuals with Alzheimer's disease

Walking in daily life places high demands on the interplay between cognitive and motor functions. A well-functioning dual-tasking ability is thus essential for walking safely. The aims were to study longitudinal changes in gait function during single- and dual-tasking over a period of two years among people with initially mild AD (n=21). Data were collected on three occasions, twelve months apart. An optical motion capture system was used for three-dimensional gait analysis. Gait parameters were examined at comfortable gait speed during single-tasking, dual-tasking naming names, and naming animals. The dual-task cost for gait speed was pronounced at baseline (names 26%, animals 35%), and remained so during the study period. A significant (p<0.05) longitudinal decline in gait speed and step length during single- and dual-tasking was observed, whereas double support time, step width and step height showed inconsistent results. Systematic visual examination of the motion capture files revealed that dual-tasking frequently resulted in gait disturbances. Three main characteristics of such disturbances were identified: Temporal disturbance, Spatial disturbance and Instability in single stance. These aberrant gait performances may affect gait stability and increase the risk of falling. Furthermore, the observed gait disturbances can contribute to understanding and explaining previous reported gait variability among individuals with AD. However, the role that dual-task testing and aberrant dual-task gait performance play in the identification of individuals with early signs of cognitive impairment and in predicting fall risk in AD remains to be studied.

The effect of exercise on behavioral and psychological symptoms of dementia: towards a research agenda

BACKGROUND

Behavioral and psychological symptoms of dementia (BPSD) are common and are core symptoms of the condition. They cause considerable distress to the person with dementia and their carers and predict early institutionalization and death. Historically, these symptoms have been managed with anxiolytic and antipsychotic medication. Although potentially effective, such medication has been used too widely and is associated with serious adverse side-effects and increased mortality. Consequently, there is a need to evaluate non-pharmacological therapies for behavioral and psychological symptoms in this population. One such therapy is physical activity, which has widespread health benefits. The aim of this review is to summarize the current findings of the efficacy of physical activity on BPSD.

METHOD

Published articles were identified using electronic and manual searches. Rather than systematically aggregating data, this review adopted a rapid critical interpretive approach to synthesize the literature.

RESULTS

Exercise appears to be beneficial in reducing some BPSD, especially depressed mood, agitation, and wandering, and may also improve night-time sleep. Evidence of the efficacy of exercise on improving other symptoms such as anxiety, apathy, and repetitive behaviors is currently weak or lacking.

CONCLUSION

The beneficial effect of exercise type, its duration, and frequency is unclear although some studies suggest that walking for at least 30 minutes, several times a week, may enhance outcome. The methodological shortcomings of current work in this area are substantial. The research and clinical implications of current findings are discussed.

Comparing day care at green care farms and at regular day care facilities with regard to their effects on functional performance of community-dwelling older people with dementia

Day care at green care farms (GCFs) is a new care modality for community-dwelling older people with dementia. In view of the more physical and normal daily life activities available at GCFs than at RDCFs, we investigated whether functional decline differed between subjects from both day care settings. In this observational cohort study, primary caregivers of 47 subjects from GCFs and 41 subjects from RDCFs rated the subjects’ functional performance three times during one year. They also provided information on the subjects’ diseases and medication use. Generally, no significant change over time in functional performance, the number of diseases and the number of medications was observed, and no differences in these rates of change were found between subjects from both day care settings. This study suggests that GCFs are not more effective in maintaining functional performance or slowing down its decline in community-dwelling older people with dementia than RDCFs.

The effect of regular walks on various health aspects in older people with dementia: protocol of a randomized-controlled trial

BACKGROUND

Physical activity has proven to be beneficial for physical functioning, cognition, depression, anxiety, rest-activity rhythm, quality of life (QoL), activities of daily living (ADL) and pain in older people. The aim of this study is to investigate the effect of walking regularly on physical functioning, the progressive cognitive decline, level of depression, anxiety, rest-activity rhythm, QoL, ADL and pain in older people with dementia.

METHODS/DESIGN

This study is a longitudinal randomized controlled, single blind study. Ambulatory older people with dementia, who are regular visitors of daily care or living in a home for the elderly or nursing home in the Netherlands, will be randomly allocated to the experimental or control condition. Participants of the experimental group make supervised walks of 30 minutes a day, 5 days a week, as part of their daily nursing care. Participants of the control group will come together three times a week for tea or other sedentary activities to control for possible positive effects of social interaction. All dependent variables will be assessed at baseline and after 6 weeks, and 3, 6, 9, 12 and 18 months of intervention. The dependent variables include neuropsychological tests to assess cognition, physical tests to determine physical functioning, questionnaires to assess ADL, QoL, level of depression and anxiety, actigraphy to assess rest-activity rhythm and pain scales to determine pain levels. Potential moderating variables at baseline are: socio-demographic characteristics, body mass index, subtype of dementia, apolipoprotein E (ApoE) genotype, medication use and comorbidities.

DISCUSSION

This study evaluates the effect of regular walking as a treatment for older people with dementia. The strength of this study is that 1) it has a longitudinal design with multiple repeated measurements, 2) we assess many different health aspects, 3) the intervention is not performed by research staff, but by nursing staff which enables it to become a routine in usual care. Possible limitations of the study are that 1) only active minded institutions are willing to participate creating a selection bias, 2) the drop-out rate will be high in this population, 3) not all participants will be able to perform/understand all tests.

Effects of a motor and multisensory-based approach on residents with moderate-to-severe dementia

Involving institutionalized people with dementia in their routines may be challenging, particularly in advanced stages of the disease. Motor and multisensory stimulation may help to maintain or improve residents' remaining abilities such as communication and self-care. This study examines the effects of a motor and multisensory-based approach on the behavior of 6 residents with moderate-to-severe dementia. A single-group, pre- and post test design was conducted. Motor and multisensory stimulation strategies were implemented in residents' morning care routines by staff, after the provision of training and assistance. Twelve video recordings of morning care (6 pre- and 6 post interventions) were coded for the type of residents' behavior. Results showed a tendency toward improvements in residents' levels of caregiver-direct gaze, laughing and engagement, and a reduction of closed eyes, during morning care. The introduction of a motor and multisensory-based approach in care routines may improve residents' engagement and attention to the environment.

Anxiety and related symptoms in older persons with dementia: directions for practice

Anxiety disorders and related symptoms commonly occur in older people with cognitive impairment or dementia, significantly worsening functioning and reducing quality of life. This review of the literature outlines the extent of the problem, and focuses on current best practices in psychosocial interventions anxiety in persons with dementia. Discussion follows on promising nonpharmacological interventions that are recommended for further consideration and future research.

Non-pharmacological approaches for dementia that informal carers might try or access: a systematic review

OBJECTIVE

To review non-drug treatments for dementia; to provide a source of evidence for informal carers who want ideas about non-drug approaches for dementia, that they might try or that they could try to access. The systematic review addresses: what non-drug treatments work and what do they work for? What non-drug treatments might work and what for? What non-drug treatments do not work?

METHODS

Literature searches of seven electronic databases (AMED, CINAHL, EMBASE, MEDLINE, PSYCINFO, Cochrane Library of Systematic Reviews and DARE) were carried out in November 2007 using the following search terms (or derivatives): dementia/Alzheimer's AND Review AND non-drug therapies and aimed at finding systematic reviews.

RESULTS

Thirty-three reviews were identified; 25 were judged to be high or good quality. Studies within these systematic reviews were characterised by weak study designs with small sample numbers. Three interventions were found to be effective for use with particular symptoms of dementia: music or music therapy, hand massage or gentle touch and physical activity/exercise.

CONCLUSIONS

Whilst informal carers can apply some of the interventions highlighted in the home setting at little or no cost to themselves or to health or social care services, others are likely to require training or instruction. Service providers and commissioners should explore current and future provision of more structured group activities for people with dementia; in particular the provision of group music therapy and group exercise activities that meet the needs of both the person with dementia and their carer.

Personalized dementia care: proven effectiveness of psychosocial interventions in subgroups

Many psychosocial intervention studies report effects in subgroups of people with dementia. Insight into the characteristics of these subgroups is important for care practice. This study reviews personal characteristics of people with dementia (living in the community or in an institution) that are related to positive outcomes of psychosocial interventions. Electronic databases and key articles were searched for effect studies published between January 1990 and February 2008. Outcome measures were clustered into categories such as cognitive functioning, behavioural functioning and mental health. Seventy-one studies showed positive outcomes on psychosocial interventions, such as decreased depression and less behavioural problems, related to personal characteristics of people with dementia, such as gender, type or severity of dementia, presence of behavioural or mental health problems, and living situation. For people with dementia living in the community positive effects were most frequently found in the persons with mild to severe dementia not otherwise specified and with mild to moderate Alzheimer's Disease. For people with dementia living in an institution positive effects were found most frequently in the subgroups moderate to severe dementia, severe to very severe dementia and in the subgroup with behavioural problems. This study provides a unique overview of characteristics that are related to effective intervention outcomes. It also suggests that more research will lead to a better understanding of which care and welfare interventions are effective for specific subgroups of people with dementia.

The concept of green care farms for older people with dementia

In the Netherlands community-dwelling older people with dementia can attend regular day care services (RDCS). Since approximately 2000, farms (so-called ‘green care farms’) also offer day care. The present study introduces the concept of green care farms for older people with dementia. We further provide an integrative framework for the expected health benefits of day care at green care farms (GCF) for older people with dementia. We present an overview of evidence for dementia related interventions that correspond with the current developments in health care (i.e. environmental, activity-based and psychosocial interventions), and that are relevant for day care. We subsequently focus on the differences between day care at GCF and RDCS with regard to these interventions, and describe the integrative framework for the expected health benefits of GCF for older people with dementia. We conclude that at GCF interventions are naturally integrated in the environment. They are present simultaneously and continuously, which is more difficult to realize in RDCS. We hypothesize that GCF have more health benefits for older people with dementia than RDCS.

Group physical activity for demented older adults feasibility and effectiveness

OBJECTIVES

(1) To examine the feasibility of group physical activity in a day-care routine. (2) To assess the impact of this programme on functional fitness.

DESIGN

Ten-week observational period, followed by 12 weeks of intervention in randomized controlled design, followed by 12 weeks of intervention only.

SETTING

A day-care centre for demented older individuals.

PARTICIPANTS

Twenty-nine demented (Mini-Mental State Exam score 13.3 +/- 5.83) day-care attendees, mean +/- SD age 76.9 +/- 6.72.

INTERVENTION

Group physical activity vs. social activity, followed by increased-intensity physical activity for both groups.

MEASUREMENTS

Performance rate (PR) in physical activity sessions, Timed Get Up and Go (TGUG), Sit-to-Stand (STS) and Functional Reach (FR).

RESULTS

Approximately 60% of the participants performed almost all movements or repetitions in both intervention phases. No improvements were observed following the first phase of physical activity. A reduction of 3.2 seconds (+/-1.2 SE) was noted in the time needed to perform the TGUG following the increased-intensity physical activity.

CONCLUSION

A carefully tailored group physical activity, conducted twice weekly with a group of 12-15 participants in a medium size room, and led by a physical activity teacher assisted by a staff aide, is feasible. Although physical activity performed mainly while sitting is ineffective, it can be effective to a meaningful degree when performed while standing or walking.
