Difficult behaviors in long-term care patients with dementia

Comparison of Emotion Recognition in Young People, Healthy Older Adults, and Patients with Mild Cognitive Impairment

BACKGROUND

The basic discrete emotions, namely, happiness, disgust, anger, fear, surprise, and sadness, are present across different cultures and societies. Facial emotion recognition is crucial in social interactions, but normal and pathological aging seem to affect this ability. The present research aims to identify the differences in the capacity for recognition of the six basic discrete emotions between young and older healthy controls (HOC) and mildly cognitively impaired patients (MCI).

METHOD

The sample (N = 107) consisted of 47 young adults, 27 healthy older adults, and 33 MCI patients. Several neuropsychological scales were administered to assess the cognitive state of the participants, followed by the emotional labeling task on the Ekman 60 Faces test.

RESULTS

The MANOVA analysis was significant and revealed the presence of differences in the emotion recognition abilities of the groups. Compared to HOC, the MCI group obtained a significantly lower number of hits on fear, anger, disgust, sadness, and surprise. The happiness emotion recognition rate did not differ significantly among the three groups. Surprisingly, young people and HOC did not show significant differences.

CONCLUSIONS

Our results demonstrated that MCI was associated with facial emotion recognition impairment, whereas normal aging did not seem to affect this ability.

Behaviour assessment tools in long-term care homes in Canada: a survey

OBJECTIVE

Many people living in long-term care homes (LTCH) experience changes in behaviour termed the behavioural and psychological symptoms of dementia (BPSD). The valid and reliable assessment of BPSD is essential to guide treatment and monitor the effect of interventions. The aim of this study was to identify behavioural assessment tools implemented in LTCH and factors that impact on their use in clinical care.

METHODS

We completed an online mixed-design survey of 300 randomly selected Canadian LTCH between September and November 2018. Respondents were asked to report tools used, reasons for use, methods of administration, training/supports available, confidence in use and challenges faced. Survey results were summarized descriptively and the correlation between implementation supports and confidence examined. Free-text responses were analysed qualitatively.

RESULTS

Of 300 LTCH invited to participate, 103 completed the survey. Homes reported using a mean 2.2 ± 1.1 (range 0-7) different tools. The two most commonly used tools were the Dementia Observation System (DOS) and Cohen-Mansfield Agitation Inventory (CMAI). Overall confidence in most aspects of tool use was reported to be high, with workload identified as the greatest challenge. Training and supports correlated with confidence in tool use. Qualitative findings indicate tools provide valuable data to understand behaviours, facilitate team communication, target interventions and track outcomes.

CONCLUSIONS

Behavioural assessment tools, in particular a direct observation tool, are widely used in clinical care in Canadian LTCH. Education, enhanced resources, leadership support and applications of technology represent opportunities to improve their use.

Extent and Factors Associated with Adherence to Antidepressant Treatment During Acute and Continuation Phase Depression Treatment Among Older Adults with Dementia and Major Depressive Disorder

PURPOSE

Little is known about adherence to antidepressant treatment during acute and continuation phase of depression among older adults with dementia and newly diagnosed major depressive disorders (MDD). This study estimated the extent of and factors associated with adherence to acute and continuation phase antidepressant treatment among older adults with dementia and newly diagnosed MDD.

METHODS

We conducted a retrospective cohort study using the Medicare 5% sample claims data (2012-2013) among older adults (age≥65 years) with dementia who were newly diagnosed with MDD. Intake period of our study was from 01-May-2012 through 30-April-2013. The dependent variables of this study were acute and continuation phase depression treatment adherence. Factors associated with acute and continuation phase antidepressant treatment adherence were identified using multiple logistic regression analyses.

RESULTS

The final study sample consisted of 6239 [adherent: N=4644 (74.44%)] and 5617 [adherent: N=3584 (63.81%)] older adults with dementia and MDD during the acute and continuation phase treatment, respectively. During the acute phase, only race/ethnicity was significantly associated with adherence to depression treatment, whereas race/ethnicity and baseline antipsychotic use were significantly associated with adherence to depression treatment during the continuation phase.

CONCLUSION

Approximately, 74% and 64% older adults with dementia and MDD were adherent to acute and continuation phase antidepressant treatment in this nationally representative sample of Medicare beneficiaries, and we identified several modifiable and non-modifiable factors associated with adherence.

Diagnosing and Treating Depression in Patients with Alzheimer's Disease

Although cognitive and functional impairment are the hallmark features of Alzheimer's disease (AD), neuropsychiatric symptoms associated with AD account for increased rates of disability and profoundly impact the quality of life of both patients and their caregivers. This narrative review of current evidence provides practical guidance in diagnosing and managing depression in patients with AD using pharmacological and nonpharmacological interventions. After apathy, depression is the second most common neuropsychiatric symptom in AD. Diagnosing late-life depression (LLD), particularly in those affected by AD, is complicated because older patients may not meet the criteria for a major depressive disorder. Clinically, late-life depression and dementia can be indistinguishable. Although these two entities are now thought to be related, the pathologic mechanisms remain unclear. Evidence suggests that LLD may be a prodromal symptom of neurodegenerative disease. The various geropsychiatric measures currently used to diagnose, rate the severity of, and monitor the progress of treatment for depression are imperfect. Neuroimaging represents a promising avenue toward understanding the complex pathophysiologic relationships between dementia and LLD, and will support the pursuit of biomarker-driven diagnosis and treatment. Nonpharmacologic interventions to relieve depression in persons with cognitive impairment and dementia include emotion-oriented therapies, behavioral and cognitive-behavioral modification programs, and structured activity programs. Sensory-stimulation therapies and multisensory approaches show some promise for successfully treating depression in patients with dementia, but further rigorous research is needed to establish their validity. Clinical consensus and research appear to support selective serotonin reuptake inhibitors as a first choice for the pharmacological treatment of depression in patients with dementia. However, initial support for these therapies remains variable, and further investigation is needed. Extra care is required in prescribing to this population because of the generally high level of medical and psychiatric comorbidity and the potential difficulty in assessing the cognitively impaired patient's response.

Integrative review: Persistent vocalizations among nursing home residents with dementia

ABSTRACTBackground:Nursing home (NH) residents with dementia commonly exhibit persistent vocalizations (PVs), otherwise known in the literature as disruptive or problematic vocalizations. Having a better understanding of PVs and the research completed to date on this phenomenon is important to guide further research and clinical practice in NHs. This integrative review examines the current literature on the phenomenon of PVs among NH residents with dementia.

METHODS

We conducted a search in the PubMed, Scopus, Ovid Medline, and CINAHL databases for articles published in English. Articles were included if the focus was specifically on research involving vocal behaviors of older adults with dementia residing in NHs.

RESULTS

Our literature search revealed eight research articles that met the inclusion criteria. These studies were published in 2011 or earlier and involved small sample sizes. Seven of these studies were descriptive and the eighth was a non-pharmacological intervention study for PVs exhibited by NH residents with dementia. These studies were vastly different in their labeling, definitions, and categorization of the PVs as well as methods of measuring PVs.

CONCLUSION

The heterogeneity of the evidence limits the ability to make recommendations for practice. Given the paucity of research on this phenomenon; recommendations for additional research are given.

Emerging treatments for the behavioral and psychological symptoms of dementia

Dementia is referred to a loss of memory and decline in other mental abilities at levels critical enough to hinder performance of daily activities. It can be of several types, depending on the underlying pathophysiology. The behavioral and psychological symptoms of dementia (BPSD) are various, but the most clinically significant are depression, apathy, and anxiety. Other BPSD include agitation, aberrant motor behavior, elation, hallucinations, and alterations in sleep and appetite. About 90% of sufferers of dementia are affected by BPSD during the course of the illness. These symptoms occur in demented patients irrespective of the dementia subtype. However, there has not been significant development in the areas of disease-modifying pharmacotherapeutics for dementia. Therefore, tackling BPSD has emerged as a research avenue in the recent past. Existing antidepressants, antipsychotics, and cholinergic agents have been extensively used in the treatment of BPSD, independently and in different combinations. However, these agents have not successful in completely alleviating such symptoms. Research in this field is going on globally, but it is still limited by various factors. There is a strong need to develop new entities and test them clinically. This review focuses on emerging treatments for the management of clinically significant BPSD.

Use of parametric speaker for older people with dementia in a residential care setting: A preliminary study of two cases

Objective/Background

Older people with dementia often show behavioural and psychological symptoms of dementia such as agitation, aggression, and depression that affect their activities of daily living, and hence reduce the quality of life of their caregivers. The aim of this study was to investigate the effects of a new technological intervention-a parametric speaker, creating a narrow personal acoustic environment, which may reduce the manifestation of behavioural and psychological symptoms of dementia symptoms.

Methods

A parametric speaker was placed on the ceiling of a large day room, and personally selected pieces of music were provided in a narrow space just under the speaker during the intervention. Two older residents with behavioural and psychological symptoms of dementia participated in the experiment.

Results

Playing pieces of favorite music via the parametric speaker decreased their behavioural and psychological symptoms of dementia during the intervention. In addition, this intervention reduced the burden on caregivers. One of the advantages of using parametric speaker was being able to create a personal space in a common room.

Conclusion

We considered that the parametric speaker might be useful to reduce behavioural and psychological symptoms of dementia and the burden on caregivers, providing individualized rehabilitation for the improved quality of life of residents.

Sexual disinhibition and dementia

To describe inappropriate sexual behaviour (ISB) observed in patients with dementia, we conducted searches using the Cochrane Library, PubMed, and Web of Science to find relevant articles, chapters, and books published from 1950 to 2014. Search terms used included 'hypersexuality', 'inappropriate sexual behaviors', and 'dementia'. Publications found through this indexed search were reviewed for further relevant references. Sexuality is a human's need to express intimacy, but persons with dementia may not know how to appropriately meet their needs for closeness and intimacy due to their decline in cognition. Generally, the interaction among brain, physical, psychological, and environmental factors can create what we call ISB. The most likely change in the sexual behaviour of a person with dementia is indifference. However, ISB in dementia appear to be of two types--intimacy-seeking and disinhibited--that differ in their association with dementia type, dementia severity and, possibly, other concurrent behavioural disorder. Tensions develop from uncertainties regarding which, or when, behaviours are to be considered 'inappropriate' (i.e. improper) or abnormal. While most ISB occur in the moderate to severe stages of Alzheimer's dementia, they may also be seen in early stages of frontotemporal dementia because of the lack of insight and disinhibition. ISB are often better managed by non-pharmacological means, as patients may be less responsive to psychoactive therapies, but non-pharmacological interventions do not always stop the behaviour.

Developing a Referral Protocol for Community-Based Occupational Therapy Services in Taiwan: A Logistic Regression Analysis

Because resources for long-term care services are limited, timely and appropriate referral for rehabilitation services is critical for optimizing clients' functions and successfully integrating them into the community. We investigated which client characteristics are most relevant in predicting Taiwan's community-based occupational therapy (OT) service referral based on experts' beliefs. Data were collected in face-to-face interviews using the Multidimensional Assessment Instrument (MDAI). Community-dwelling participants (n = 221) ≥ 18 years old who reported disabilities in the previous National Survey of Long-term Care Needs in Taiwan were enrolled. The standard for referral was the judgment and agreement of two experienced occupational therapists who reviewed the results of the MDAI. Logistic regressions and Generalized Additive Models were used for analysis. Two predictive models were proposed, one using basic activities of daily living (BADLs) and one using instrumental ADLs (IADLs). Dementia, psychiatric disorders, cognitive impairment, joint range-of-motion limitations, fear of falling, behavioral or emotional problems, expressive deficits (in the BADL-based model), and limitations in IADLs or BADLs were significantly correlated with the need for referral. Both models showed high area under the curve (AUC) values on receiver operating curve testing (AUC = 0.977 and 0.972, respectively). The probability of being referred for community OT services was calculated using the referral algorithm. The referral protocol facilitated communication between healthcare professionals to make appropriate decisions for OT referrals. The methods and findings should be useful for developing referral protocols for other long-term care services.

Long-term effects of a 12 weeks high-intensity functional exercise program on physical function and mental health in nursing home residents with dementia: a single blinded randomized controlled trial

Background

Research indicates that exercise can have a positive effect on both physical and mental health in nursing home patients with dementia, however the lasting effect is rarely studied. In a previously published article we investigated the immediate effect of a 12 weeks functional exercise program on physical function and mental health in nursing home residents with dementia. In this paper we studied the long-term effect of this exercise program. We explored the differences between the exercise and control group from baseline to 6 months follow-up and during the detraining period from month 3 to 6.

Methods

A single blind, randomized controlled trial was conducted and a total of 170 nursing home residents with dementia were included. The participants were randomly allocated to an intervention (n = 87) or a control group (n = 83). The intervention consisted of intensive strengthening and balance exercises in small groups twice a week for 12 weeks. The control condition was leisure activities. Thirty participants were lost between baseline and six-month follow-up. Linear mixed model analyses for repeated measurements were used to investigate the effect of exercise after detraining period.

Results

The exercise group improved their scores on Berg Balance Scale from baseline to 6 months follow-up by 2.7 points in average. The control group deteriorated in the same period and the difference between groups was statistically significant (p = 0.031). The exercise group also scored better on NPI agitation sub-score after 6 months (p = 0.045).

Conclusion

The results demonstrate long-time positive effects of a high intensity functional exercise program on balance and indicate a positive effect on agitation, after an intervention period of 12 weeks followed by a detraining period of 12 weeks.

Influence of Aquariums on Resident Behavior and Staff Satisfaction in Dementia Units

The influence of an aquarium on resident behavior and staff job satisfaction in three dementia units was examined. The sample consisted of 71 individuals with dementia and 71 professional staff. A pretest–posttest design was utilized. Baseline resident behavior and staff satisfaction were obtained, and an aquarium was introduced into the setting. Post-behavioral assessment and job satisfaction surveys were completed. Residents’ behaviors improved along four domains: uncooperative, irrational, sleep, and inappropriate behaviors. The overall residents’ behavior score was significantly improved after an aquarium was introduced, F = 15.60, p < .001. Their mean disruptive behavior score decreased from 67.2 to 58.2. The staff’s satisfaction score significantly improved, F = 35.34, p < .001. Pretest to posttest mean scores improved from 149.4 to 157.9. Aquariums are an innovative way for animal-assisted therapy and nature to be introduced to specialized dementia units in long-term care.

Noncontingent reinforcement of disruptive behaviors in personal care home settings

The purpose of this case study was to examine the potential of using noncontingent reinforcement (NCR) to reduce the frequency of disruptive behaviors of three elderly persons in personal care home (PCH) settings. Assessment indicated that participants were engaging in the disruptive behaviors to obtain social attention from PCH staff. Social attention, up to 1 min of staff making eye contact with the participant and directing positive verbal statements toward the participant, was given on a fixed time interval (from morning through early evening) beginning every 20 min and fading to every 30 min. Results indicate that NCR reduced the frequency of the disruptive behaviors.

Underrecognition and undertreatment of dementia in Italian nursing homes

OBJECTIVE

To determine the prevalence of dementia diagnoses and the use of antidementia drugs in a cohort of Italian older nursing home (NH) residents.

DESIGN

Cross-sectional study.

SETTING

The NH residents participating in 2 studies: the U.L.I.S.S.E. study and the Umbria Region survey.

PARTICIPANTS

A total of 2215 nursing home residents.

MEASUREMENT

Each resident underwent a comprehensive geriatric assessment at baseline by means of the RAI MDS 2.0. Dementia diagnosis was based on ICD-9 codes.

RESULTS

The prevalence of dementia diagnosis according to ICD-9 codes was 50.7% (n = 1123), whereas 312 subjects had cognitive impairment with a cognitive performance scale score ≥3 without a diagnosis of dementia. Only 56 NH residents were treated (5% of the sample) and the main drugs used were cholinesterase inhibitor, whereas only 1 subject was treated with memantine. Limiting our analysis to patients with mild to moderate Alzheimer's disease, who are those reimbursed by the public health care system for receiving antidementia drugs, the percentage rose to 11.3%.

CONCLUSION

These findings demonstrate a high rate of underdiagnosis and undertreatment of dementia in Italian NH residents. Potential explanations include the lack of systematic assessment of cognitive functions, the limitations to antidementia drug reimbursement, the complexity of the reimbursement procedure itself, and the high prevalence of patients with severe dementia. Older NH residents still lack proper access to state-of-the-art diagnosis and treatment for a devastating condition such as dementia.

Treatment of Alzheimer's disease in Brazil: II. Behavioral and psychological symptoms of dementia

This article reports the recommendations of the Scientific Department of Cognitive Neurology and Aging of the Brazilian Academy of Neurology for the treatment of Alzheimer's disease (AD) in Brazil, with special focus on behavioral and psychological symptoms of dementia (BPSD). It constitutes a revision and broadening of the 2005 guidelines based on a consensus involving researchers (physicians and non-physicians) in the field. The authors carried out a search of articles published since 2005 on the MEDLINE, LILACS and Cochrane Library databases. The search criteria were pharmacological and non-pharmacological treatment of the behavioral and psychological symptoms of AD. Studies retrieved were categorized into four classes, and evidence into four levels, based on the 2008 recommendations of the American Academy of Neurology. The recommendations on therapy are pertinent to the dementia phase of AD. Recommendations are proposed for the treatment of BPSD encompassing both pharmacological (including acetyl-cholinesterase inhibitors, memantine, neuroleptics, anti-depressives, benzodiazepines, anti-convulsants plus other drugs and substances) and non-pharmacological (including education-based interventions, physiotherapy, occupational therapy, music therapy, therapy using light, massage and art therapy) approaches. Recommendations for the treatment of cognitive disorders of AD symptoms are included in a separate article of this edition.

Changes in nursing burden following memantine for agitation and aggression in long-term care residents with moderate to severe Alzheimer's disease: an open-label pilot study

BACKGROUND

Agitation and aggression are common neuropsychiatric symptoms of Alzheimer's disease (AD) with a negative impact on caregivers.

OBJECTIVE

The aim of the study was to determine whether changes in agitation and aggression would follow memantine treatment and, if so, be associated with changes in nursing burden in institutionalized patients with moderate to severe AD.

STUDY DESIGN

This was a 3-month open-label trial of memantine.

SETTING

The setting was two long-term care facilities.

PATIENTS

Thirty-one institutionalized patients with moderate to severe AD and significant behavioural and psychiatric symptoms were included in the study.

INTERVENTION

Memantine was titrated to a target dose of 10 mg twice daily.

MAIN OUTCOME MEASURE

Effectiveness was assessed by the change in the Neuropsychiatric Inventory-Nursing Home (NPI-NH) agitation/aggression subscale and Clinical Global Impression of Change (CGI-C) scale using the intent-to-treat population. To establish caregiver impact, the effect on nursing burden was measured by the Modified Nursing Care Assessment Scale (primary outcome). As a secondary analysis, the caregiver distress subscale of the NPI-NH was examined, as well as changes in as required (pro re nata [prn]) psychotropic medication use.

RESULTS

Twenty-four patients completed the study. A significant decrease in agitation and aggression (F-test with 3 and 90 degrees of freedom [F(3,90)] = 3.721, p = 0.014) was demonstrated following memantine, with 48% of patients improving (either much improved or minimally improved) on the CGI-C scale. In addition, nursing burden (t-test with 30 degrees of freedom [t(30)] = 3.02, p = 0.005), caregiver distress (F(3,90) = 4.125, p = 0.009) and the use of prn psychotropics decreased following memantine treatment (Z = -1.99, p = 0.046). Fourteen patients experienced at least one adverse event during memantine treatment. The most common adverse event associated with treatment was somnolence (n = 5).

CONCLUSION

The results of this study suggest that the decreased agitated and aggressive behaviour in institutionalized patients with moderate to severe AD following treatment with memantine was accompanied by improvements in nursing burden and decreased psychotropic use. These findings should be confirmed in a larger, controlled trial.

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.

Overview of non-pharmacological intervention for dementia and principles of brain-activating rehabilitation

Non-pharmacological interventions for dementia are likely to have an important role in delaying disease progression and functional decline. Research into non-pharmacological interventions has focused on the differentiation of each approach and a comparison of their effects. However, Cochrane Reviews on non-pharmacological interventions have noted the paucity of evidence regarding the effects of these interventions. The essence of non-pharmacological intervention is dependent of the patients, families, and therapists involved, with each situation inevitably being different. To obtain good results with non-pharmacological therapy, the core is not 'what' approach is taken but 'how' the therapists communicate with their patients. Here, we propose a new type of rehabilitation for dementia, namely brain-activating rehabilitation, that consists of five principles: (i) enjoyable and comfortable activities in an accepting atmosphere; (ii) activities associated with empathetic two-way communication between the therapist and patient, as well as between patients; (iii) therapists should praise patients to enhance motivation; (iv) therapists should try to offer each patient some social role that takes advantage of his/her remaining abilities; and (v) the activities should be based on errorless learning to ensure a pleasant atmosphere and to maintain a patient's dignity. The behavioral and cognitive status is not necessarily a reflection of pathological lesions in the brain; there is cognitive reserve for improvement. The aim of brain-activating rehabilitation is to enhance patients' motivation and maximize the use of their remaining function, recruiting a compensatory network, and preventing the disuse of brain function. The primary expected effect is that patients recover a desire for life, as well as their self-respect. Enhanced motivation can lead to improvements in cognitive function. Amelioration of the behavioral and psychological symptoms of dementia and improvements in activities of daily living can also be expected due to the renewed positive attitude towards life. In addition, improvements in the quality of life for both patients and caregivers is an expected outcome. To establish evidence for non-pharmacological interventions, research protocols and outcome measures should be standardized to facilitate comparison among studies, as well as meta-analysis.

Sexual aggression between residents in nursing homes: literature synthesis of an underrecognized problem

Evidence exists suggesting that most sexual aggression against older adults occurs in long-term care facilities. Fellow residents are the most common perpetrators, often demonstrating inappropriate hypersexual behavior caused by dementing illness. This resident-to-resident sexual aggression (RRSA) is defined as sexual interactions between long-term care residents that, in a community setting, at least one of the recipients would be likely to construe as unwelcome and that have high potential to cause physical or psychological distress in one or both of the involved residents. Although RRSA may be common, and physical and psychological consequences for victims may be significant, this phenomenon has received little direct attention from researchers. This is a review of the existing literature and relevant related research examining elder sexual abuse and hypersexual behavior that describes the epidemiological features of this phenomenon, including risk factors for perpetrators and victims. The legitimate and recognized need for nursing home residents, even those with advanced dementing illness, to express themselves sexually makes preventing and managing sexual aggression in nursing homes more challenging. This review discusses the ethical dilemma this situation creates and the need to evaluate the capacity to consent to sexual activity of residents with dementing illness and to re-evaluate capacity as the diseases progress. Suggestions are offered for managing incidents of RRSA and for future research, including the importance of designing effective interventions.

Review: verbal agitation in dementia: the role of discomfort

Verbal agitation (VA) is a disturbing and commonly observed behavioral symptom in people with dementia. Although several different variables contribute to VA, it seems that discomfort plays an important role. The overall objective of this article is to review the relationship between VA and discomfort among people with dementia. Specifically, this article discusses the place of discomfort within the conceptualizations of VA, empirical support for the association between discomfort and VA, and practical implications of this relationship in the assessment and treatment of VA. This article contributes to a better understanding of VA and provides recommendations for prevention and effective intervention.

Non-pharmacological management of behavioural symptoms in nursing homes

BACKGROUND

Behavioural and psychological symptoms of dementia (BPSD) are often reported in institutions for the elderly.

OBJECTIVE

To evaluate the effectiveness of a staff education intervention to manage BPSD in older people with a diagnosis of dementia.

METHODS

The trial was conducted in 16 nursing homes; 306 patients with a diagnosis of dementia and presenting BPSD were selected. Nursing homes were randomly allocated to an intervention group or a control group. An 8-week staff education and training programme was conducted in the nursing homes in the intervention group. The main outcome measures were the Cohen-Mansfield Agitation Inventory (CMAI) and an Observation Scale (OS) score. Assessments were done at baseline (W0), at the end of the 'intervention' period (W8) and 12 weeks after (W20).

RESULTS

There was a significant decrease in the global CMAI score between baseline and W8 (-7.8; p > 0.01) and between baseline and W20 (-6.5; p > 0.01) in the intervention group but not in the control group. Results of mixed linear models showed that the CMAI global score, the CMAI physically non-aggressive behaviours subscale score and verbally non-aggressive behaviours subscale score significantly decreased in the intervention group (p < 0.001) although there was no significant evolution in the control group. Direct assessment with the OS produced the same pattern of results, with a significant decrease only in the intervention group.

CONCLUSION

The intervention reduced BPSD in severely demented nursing home residents and this effect was still present 3 months after the end of the programme.

The recognition of facial expressions of emotion in Alzheimer's disease: a review of findings

OBJECTIVE

To provide a selective review of the literature on the recognition of facial expressions of emotion in Alzheimer's disease (AD), to evaluate whether these patients show variation in their ability to recognise different emotions and whether any such impairments are instead because of a general decline in cognition.

METHODS

A narrative review based on relevant articles identified from PubMed and PsycInfo searches from 1987 to 2007 using keywords 'Alzheimer's', 'facial expression recognition', 'dementia' and 'emotion processing'.

CONCLUSION

Although the literature is as yet limited, with several methodological inconsistencies, AD patients show poorer recognition of facial expressions, with particular difficulty with sad expressions. It is unclear whether poorer performance reflects the general cognitive decline and/or verbal or spatial deficits associated with AD or whether the deficits reflect specific neuropathology. This under-represented field of study may help to extend our understanding of social functioning in AD. Future work requires more detailed analyses of ancillary cognitive measures, more ecologically valid facial displays of emotion and a reference situation that more closely approximates an actual social interaction.

Die deutsche Fassung der «Serial Trial Intervention» (STI-D)

In fortgeschrittenen Demenzstadien treten häufig so genannte herausfordernde Verhaltensweisen auf, die den nicht-kognitiven Symptomen der Demenz zugerechnet werden. Sie lassen sich als Ausdruck eines unbefriedigten Bedürfnisses des Demenzkranken betrachten. Im Zuge der dargestellten Studie soll eine deutsche Fassung der Serial Trial Intervention (STI-D) entwickelt und getestet werden. Die STI gibt einen strukturierten Rahmen zum Erkennen unbefriedigter Bedürfnisse von Pflegeheimbewohnern mit Demenz und der darauf basierenden Reduktion herausfordernder Verhaltensweisen vor, unter besonderer Berücksichtigung von Schmerzen. In einem ersten Schritt erfolgt unter Einbezug von Fachexperten eine Anpassung der STI-D an die deutschen Erfordernisse. Anschließend wird in einer clusterrandomisierten, kontrollierten, verblindeten klinischen Studie mit drei Messzeitpunkten die Effektivität der STI-D getestet. Primärer Endpunkt ist dabei das Auftreten herausfordernder Verhaltensweisen, sekundäre Endpunkte sind Schmerzen, Lebensqualität sowie die Gabe von Analgetika und Psychopharmaka. Mit Ergebnissen wird im Jahr 2010 gerechnet.

Assessment and treatment approaches for behavioral disturbances associated with dementia in the nursing home: self-reports of physicians' practices

OBJECTIVES

Behavior problems are common in dementia, yet little is known about how physicians deal with these problems in practice. This article reports on a survey asking physicians to describe, with respect to the last nursing home resident with dementia they treated for behavior problems, the behaviors observed, assessment methods used, suspected etiology of the problem, types of intervention, and their reaction to the intervention process.

DESIGN

This is a descriptive study presenting responses to a Web-based questionnaire.

PARTICIPANTS

Participants were 110 physicians providing services to nursing home residents.

MEASUREMENTS

Physicians answered a close-ended questionnaire with open-ended "other" options concerning symptoms, methods of assessment, suspected etiological factors, and interventions to describe the last nursing home resident they treated for behavior problems associated with dementia.

RESULTS

Resisting care was the most frequently reported symptom (71%). Physicians were most likely to attribute the behavior problems to the indirect effects of dementia on the ability to remember, communicate, and comprehend (67%). Most (87%) reported using more than one method for treating these problems. Rate of reported use of psychotropic drugs (80%) was slightly higher than that for nonpharmacological methods (75%), with the majority (61%) reporting use of both of these methods. Standardized instruments were not used in assessment. Forty percent of the participants reported feeling satisfied or very satisfied with the intervention they provided, and close to a third (32%) reported feeling frustrated with the intervention process.

CONCLUSION

The data underscore the complexity in the treatment of behavior problems. Despite federal regulations limiting their use, the potential for side effects, and ambivalence toward such treatment, psychotropic drugs are still used for the majority of nursing home residents with behavior problems associated with dementia. On the other hand, physicians report employing nonpharmacological methods to a closely similar extent, although their role in the implementation of these treatments is less clear. Further work is needed to clarify physicians' involvement in and decision to use nonpharmacological interventions.

Antipsychotics for the treatment of behavioral and psychological symptoms of dementia (BPSD)

Behavioral and psychological symptoms of dementia (BPSD), i.e. verbal and physical aggression, agitation, psychotic symptoms (hallucinations and delusions), sleep disturbances, oppositional behavior, and wandering, are a common and potentially severe problem complicating dementia. Their prevalence is very high and it is estimated that up to 90% of patients with Alzheimer's disease (AD) may present at least one BPSD. Beside the obvious impact on the quality of life of people with dementia, BPSD are responsible for increased risk of patient institutionalization and increased costs. Furthermore, they are associated with caregivers' stress and depression. Drugs used include antipsychotics, antidepressants, anticonvulsivants, anxiolytics, cholinesterase inhibitors and N-methyl-D-aspartate receptor modulators. Among these, the most commonly used are anti-psychotics. These drugs have been used for many decades, but in the last years new compounds have been marketed with the promise of comparable efficacy but less frequent adverse effects (especially extra-pyramidal side effects). Their safety, however, has been challenged by data showing a potential increase in adverse cerebrovascular side effects and mortality. This review will summarize the pathophysiology and neuropharmacology of BPSD, it will describe the characteristics of the anti-psychotics most commonly used focusing on their efficacy and safety in BPSD.

Managing the wandering behaviour of people living in a residential aged care facility

Background  Wandering behaviour is frequently seen in older people with cognitive impairment. The prevalence of patients exhibiting wandering behaviour has been estimated to be 11.6% on traditional units and 52.7% on Alzheimer's units. Wandering is one of the core behavioural characteristics that impact on familial carers and is likely to influence the decision to place a family member in an aged care environment. Considering the possible risks associated with wandering behaviour, the successful identification and management of wandering is essential. Wandering is also a problem for caregivers in the institutionalised setting, in terms of containment, usually being addressed by securing the environment. There has been some research conducted to assist in the understanding and management of wandering behaviour; however, the findings have been diverse resulting in a level of confusion about the best approaches to take. Objectives  This review aims to present the best available evidence on the management of wandering in older adults who reside in an aged care facility (both high and low care). Search strategy  An extensive search of keywords contained in the title and abstract, and relevant MeSH headings and descriptor terms was performed on the following databases: MEDLINE, CINAHL, PsychINFO, AGELINE, Cochrane Library, Embase, APAIS Health, Current Contents, Dare, Dissertation Abstracts, Personal Communication, Social Science Index.

Managing the wandering behaviour of people living in a residential aged care facility

BACKGROUND

Wandering behaviour is frequently seen in older people with cognitive impairment. The prevalence of patients exhibiting wandering behaviour has been estimated to be 11.6% on traditional units and 52.7% on Alzheimer's units. Wandering is one of the core behavioural characteristics that impact on familial carers and is likely to influence the decision to place a family member in an aged care environment. Considering the possible risks associated with wandering behaviour, the successful identification and management of wandering is essential. Wandering is also a problem for caregivers in the institutionalised setting, in terms of containment, usually being addressed by securing the environment. There has been some research conducted to assist in the understanding and management of wandering behaviour; however, the findings have been diverse resulting in a level of confusion about the best approaches to take.

OBJECTIVES

This review aims to present the best available evidence on the management of wandering in older adults who reside in an aged care facility (both high and low care).

SEARCH STRATEGY

An extensive search of keywords contained in the title and abstract, and relevant MeSH headings and descriptor terms was performed on the following databases: MEDLINE, CINAHL, PsychINFO, AGELINE, Cochrane Library, Embase, APAIS Health, Current Contents, Dare, Dissertation Abstracts, Personal Communication, Social Science Index.

SELECTION CRITERIA

Papers were selected if they focused on the treatment of wandering in an institutional setting. Some studies were not specifically examining wanderers over the age of 65 years as per the protocol requirements, but were included as it was felt that their findings could be applied to this age group.

DATA COLLECTION AND ANALYSIS

Study design and quality were tabulated and relative risks, odds ratios, mean differences and associated 95% confidence intervals were calculated from individual comparative studies containing count data where possible. All other data were presented in a narrative summary.

RESULTS

Searches identified one care protocol, two systematic reviews and 24 other studies that satisfied the inclusion criteria. The following recommendations are divided into four categories of interventions (environmental, technology and safety, physical/psychosocial, and caregiving support and education) with only Level 1, 2 or 3 evidence presented.

ENVIRONMENTAL MODIFICATIONS

Gridlines placed in front of doors or covering exit door doorknobs or panic bars may be effective at reducing exit-seeking behaviour (Level 3b).

TECHNOLOGY AND SAFETY

Mobile locator devices may be effective at enabling quick location of wandering residents (Level 3c).

PHYSICAL/PSYCHOSOCIAL INTERVENTIONS

Implementation of a walking group or an exercise program may reduce the incidence of disruptive wandering behaviour (Level 3b). Use of air mat therapy may reduce wandering behaviour for at least 15 min post therapy (Level 2). Providing music sessions (and reading sessions) may keep residents from wandering during the period of the session (Level 3b).

CAREGIVING SUPPORT AND EDUCATION

There is no evidence to support any interventions.

CONCLUSIONS

The majority of the available research for which the guidelines are based upon was derived from observational studies or expert opinion (Level of evidence 3 or 4). More rigorous research is required to demonstrate the efficacy of these recommendations.
