Behavioural and Psychological Symptoms of Dementia (BPSD)

Demencija je sindrom koji obuhvaća tri klinička elementa: smanjenu kogniciju, nedostatke u sposobnostima prilagodbe (tj. svakodnevnim životnim aktivnostima [ADL; prema eng. activities of daily living] i/ili instrumentalnim životnim aktivnostima [IADL; prema engl. instrumental activities of daily living]) te poremećaje u ponašanju. Prema novijim istraživanjima, unatoč smanjenoj kogniciji, poremećaji u ponašanju predstavljaju glavni izvor stresa i/ili tereta za njegovatelja pacijenta. Istaknuti odnos između poremećaja u ponašanju i stresa/tereta njegovatelja vrlo je često glavni okidač za hospitalizaciju pacijenta. Svrha je ovog rada ponuditi kratak osvrt na fenomenologiju i određene odabrane kliničke aspekte ponašajnih simptoma demencije.Dementia is a syndrome that entails 3 clinical elements: decline in cognition, deficits in adaptive capacities (i.e., activities of daily living [ADL] and/or instrumental activities of daily living [IADL]) and behavioural disturbances. Intriguingly, despite the cognitive decline recent research indicates that the behavioural disturbances are the major source of stress and/or burden for the caregiver of the patient. Furthermore, the prominent relationship between behavioural disturbance and stress/burden of the caregiver is quite often the major trigger for institutionalization of the patient. The purpose of this presentation is to briefly review the phenomenology and some selected clinical aspects of the behavioural symptoms of dementia

A Randomised, Blinded, Placebo-Controlled Trial in Dementia Patients Continuing or Stopping Neuroleptics (The DART-AD Trial)

In a randomized trial of patients with dementia, Clive Ballard and colleagues show that withdrawal of neuroleptics had no overall detrimental effect, and by some measures improved, functional and cognitive status

A feasibility study comparing UK older adult mental health inpatient wards which use protected engagement time with other wards which do not: Study protocol

© 2016 Nolan et al. Background: Protected engagement time (PET) is a concept of managing staff time on mental health inpatient wards with the aim of increasing staff and patient interaction. Despite apparent widespread use of PET, there remains a dearth of evidence as to how it is implemented and whether it carries benefits for staff or patients. This protocol describes a study which is being carried out on mental health wards caring for older adults (aged over 65) in England. The study shares a large proportion of the procedures, measures and study team membership of a recently completed investigation of the impact of PET in adult acute mental health wards. The study aims to identify prevalence and components of PET to construct a model for the intervention, in addition to testing the feasibility of the measures and procedures in preparation for a randomised trial. Methods/design: The study comprises four modules and uses a mixed methods approach. Module 1 involves mapping all inpatient wards in England which provide care for older adults, including those with dementia, ascertaining how many of these provide PET and in what way. Module 2 uses a prospective cohort method to compare five older adult mental health wards that use PET with five that do not across three National Health Service (NHS) Foundation Trust sites. The comparison comprises questionnaires, observation tools and routinely collected clinical service data and combines validated measures with questions developed specifically for the study. Module 3 entails an in-depth case study evaluation of three of the participating PET wards (one from each NHS Trust site) using semi-structured interviews with patients, carers and staff. Module 4 describes the development of a model and fidelity scale for PET using the information derived from the other modules with a working group of patients, carers and staff. Discussion: This is a feasibility study to test the application of the measures and methods in inpatient wards for older adults and develop a draft model for the intervention. The next stage will prospectively involve testing of the model and fidelity scale in randomised conditions to provide evidence for the effectiveness of PET as an intervention

Discomfort and agitation in older adults with dementia

<p>Abstract</p> <p>Background</p> <p>A majority of patients with dementia present behavioral and psychological symptoms, such as agitation, which may increase their suffering, be difficult to manage by caregivers, and precipitate institutionalization. Although internal factors, such as discomfort, may be associated with agitation in patients with dementia, little research has examined this question. The goal of this study is to document the relationship between discomfort and agitation (including agitation subtypes) in older adults suffering from dementia.</p> <p>Methods</p> <p>This correlational study used a cross-sectional design. Registered nurses (RNs) provided data on forty-nine residents from three long-term facilities. Discomfort, agitation, level of disability in performing activities of daily living (ADL), and severity of dementia were measured by RNs who were well acquainted with the residents, using the Discomfort Scale for patients with Dementia of the Alzheimer Type, the Cohen-Mansfield Agitation Inventory, the ADL subscale of the Functional Autonomy Measurement System, and the Functional Assessment Staging, respectively. RNs were given two weeks to complete and return all scales (i.e., the Cohen-Mansfield Agitation Inventory was completed at the end of the two weeks and all other scales were answered during this period). Other descriptive variables were obtained from the residents' medical file or care plan.</p> <p>Results</p> <p>Hierarchical multiple regression analyses controlling for residents' characteristics (sex, severity of dementia, and disability) show that discomfort explains a significant share of the variance in overall agitation (28%, <it>p </it>< 0.001), non aggressive physical behavior (18%, <it>p </it>< 0.01) and verbally agitated behavior (30%, <it>p </it>< 0.001). No significant relationship is observed between discomfort and aggressive behavior but the power to detect this specific relationship was low.</p> <p>Conclusion</p> <p>Our findings provide further evidence of the association between discomfort and agitation in persons with dementia and reveal that this association is particularly strong for verbally agitated behavior and non aggressive physical behavior.</p

High Degree of Heterogeneity in Alzheimer's Disease Progression Patterns

There have been several reports on the varying rates of progression among Alzheimer's Disease (AD) patients; however, there has been no quantitative study of the amount of heterogeneity in AD. Obtaining a reliable quantitative measure of AD progression rates and their variances among the patients for each stage of AD is essential for evaluating results of any clinical study. The Global Deterioration Scale (GDS) and Functional Assessment Staging procedure (FAST) characterize seven stages in the course of AD from normal aging to severe dementia. Each GDS/FAST stage has a published mean duration, but the variance is unknown. We use statistical analysis to reconstruct GDS/FAST stage durations in a cohort of 648 AD patients with an average follow-up time of 4.78 years. Calculations for GDS/FAST stages 4–6 reveal that the standard deviations for stage durations are comparable with their mean values, indicating the presence of large variations in the AD progression among patients. Such amount of heterogeneity in the course of progression of AD is consistent with the existence of several sub-groups of AD patients, which differ by their patterns of decline

Nursing home care for people with dementia and residents' quality of life, quality of care and staff well-being: Design of the Living Arrangements for people with Dementia (LAD) - study

<p>Abstract</p> <p>Background</p> <p>There is limited information available on how characteristics of the organization of nursing home care and especially group living home care and staff ratio contribute to care staff well being, quality of care and residents' quality of life. Furthermore, it is unknown what the consequences of the increasingly small scale organization of care are for the amount of care staff required in 2030 when there will be much more older people with dementia.</p> <p>Methods/Design</p> <p>This manuscript describes the design of the 'Living Arrangements for people with Dementia study' (LAD-study). The aim of this study is to include living arrangements from every part of this spectrum, ranging from large scale nursing homes to small group living homes. The LAD-study exists of quantitative and qualitative research. Primary outcomes of the quantitative study are wellbeing of care staff, quality of care and quality of life of residents. Furthermore, data concerning staff ratio and characteristics of the living arrangements such as group living home care characteristics are assessed. To get more in-depth insight into the barriers and facilitators in living arrangements for people with dementia to provide good care, focus groups and Dementia Care Mapping are carried out.</p> <p>Discussion</p> <p>Results of this study are important for policymakers, directors and staff of living arrangements providing nursing home care to people with dementia and essential for the development of methods to improve quality of care, residents' and staff well-being. Data collection will be repeated every two years, to generate knowledge on the results of changing policies in this field.</p

Calculating Stage Duration Statistics in Multistage Diseases

Many human diseases are characterized by multiple stages of progression. While the typical sequence of disease progression can be identified, there may be large individual variations among patients. Identifying mean stage durations and their variations is critical for statistical hypothesis testing needed to determine if treatment is having a significant effect on the progression, or if a new therapy is showing a delay of progression through a multistage disease. In this paper we focus on two methods for extracting stage duration statistics from longitudinal datasets: an extension of the linear regression technique, and a counting algorithm. Both are non-iterative, non-parametric and computationally cheap methods, which makes them invaluable tools for studying the epidemiology of diseases, with a goal of identifying different patterns of progression by using bioinformatics methodologies. Here we show that the regression method performs well for calculating the mean stage durations under a wide variety of assumptions, however, its generalization to variance calculations fails under realistic assumptions about the data collection procedure. On the other hand, the counting method yields reliable estimations for both means and variances of stage durations. Applications to Alzheimer disease progression are discussed

The experiences and preparedness of family carers for best interest decision-making of a relative living with advanced dementia:A qualitative study

Aim To explore the experience and the preparedness of family carers in their caregiving role as best interest decision‐makers of a relative living with advanced dementia. Background The prevalence of dementia is a global issue. The role of being a carer of a relative living with dementia does not necessarily lessen once they are admitted to a nursing home. Best interest decision‐making including end‐of‐life care decisions need to be made and reaching these choices can be challenging. The preparedness of family carers in this role needs greater understanding. Design Descriptive qualitative study. Methods During 2015 twenty semi‐structured interviews were conducted of family carers of nursing home residents living with advanced dementia, then analysed using Braun and Clarke's thematic analysis. Results Three themes were identified: (1) Caring for someone living with dementia. The impact on the carer's holistic well‐being and their experience of being a best interest decision‐maker; (2) Accessing support. The influential nature of formal and informal networks; (3) Perceived knowledge and understanding of the dementia trajectory of carers and nursing staff. Conclusion The experiences and preparedness of informal carers is a reflection of their personal response, but the distress experienced highlights the significant need of adequate support availability and of enhancing nursing staffs’ dementia expertise to maximize their role in facilitating best interest decision‐making. This has significant implications for nursing practice and for service user and nursing staff education. Considering the global impact of dementia, our findings have international relevance to similar nursing homes across the world
