Which medical and social decision topics are important after early diagnosis of Alzheimer's Disease from the perspectives of people with Alzheimer's Disease, spouses and professionals?

Outcome measures for Alzheimer's disease: A global inter-societal Delphi consensus

INTRODUCTION

We aim to provide guidance on outcomes and measures for use in patients with Alzheimer's clinical syndrome.

METHODS

A consensus group of 20 voting members nominated by 10 professional societies, and a non-voting chair, used a Delphi approach and modified GRADE criteria.

RESULTS

Consensus was reached on priority outcomes (n = 66), measures (n = 49) and statements (n = 37) across nine domains. A number of outcomes and measurement instruments were ranked for: Cognitive abilities; Functional abilities/dependency; Behavioural and neuropsychiatric symptoms; Patient quality of life (QoL); Caregiver QoL; Healthcare and treatment-related outcomes; Medical investigations; Disease-related life events; and Global outcomes.

DISCUSSION

This work provides indications on the domains and ideal pertinent measurement instruments that clinicians may wish to use to follow patients with cognitive impairment. More work is needed to develop instruments that are more feasible in the context of the constraints of clinical routine.

The experience of lived body as expressed by people with dementia: A systematic meta-synthesis

INTRODUCTION

People with dementia undergo extensive bodily changes during the course of dementia. Even though this is largely unrecognised in the literature, these changes greatly impact on the persons' experiences of living with dementia. Consequently, health care professionals and family caregivers need to be aware of the implications this has for delivering care to people with dementia. Hence, a systematic review that synthesises the knowledge on this topic is called for.

METHOD

This article presents a qualitative systematic meta-synthesis of interview studies with people with dementia. The theoretical framework of lifeworlds by van Manen provided the context for the study. The Critical Appraisal Skills Program criteria for qualitative studies were used to appraise the studies. Thirty-nine qualitative research studies were included in the review. The analysis followed the principles of interpretive synthesis.

FINDINGS

When exploring people's experiences of their body when living with dementia, four categories emerge: (1) My body works; (2) My body betrays me; (3) Understanding and adapting to my body's changes; and (4) My body in relation to others.

DISCUSSION/CONCLUSION

Every individual has their own personal experience of living with dementia; however, if health professionals fail to regard the body as more than an object, this may lead to the person's alienation both from the relation and from the body. The lived body experience has relational aspects as people with dementia are aware that others observe them, and they also observe others. Others' behaviour may affect the person's experience of body; one can perceive oneself as approved or denounced. People with dementia describe that a body that is capable and strong gives access to the world and to participation.

Psychotherapeutic interventions in individuals at risk for Alzheimer's dementia: a systematic review

BACKGROUND

Expanding technologies of early detection of Alzheimer's disease allow to identify individuals at risk of dementia in early and asymptomatic disease stages. Neuropsychiatric symptoms, such as anxiety and depression, are common in the course of AD and may be clinically observed many years before the onset of significant cognitive symptoms. To date, therapeutic interventions for AD focus on pharmacological and life style modification-based strategies. However, despite good evidence for psychotherapy in late-life depression, evidence for such therapeutic approaches to improve cognitive and emotional well-being and thereby reduce psychological risk factors in the course of AD are sparse.

METHODS

A systematic review was conducted in PUBMED, PsycINFO, Web of Science, and Clinical Trials to summarize the state of evidence on psychotherapeutic and psychoeducational interventions for individuals at risk for Alzheimer's dementia. Eligible articles needed to apply a manualized and standardized psychotherapeutic or psychoeducational content administered by trained professionals for individuals with subjective cognitive decline or mild cognitive impairment and measure mental health, quality of life or well-being.

RESULTS

The literature search yielded 32 studies that were included in this narrative summary. The data illustrates heterogeneous therapeutic approaches with mostly small sample sizes and short follow-up monitoring. Strength of evidence from randomized-controlled studies for interventions that may improve mood and well-being is scarce. Qualitative data suggests positive impact on cognitive restructuring, and disease acceptance, including positive effects on quality of life. Specific therapeutic determinants of efficacy have not been identified to date.

CONCLUSIONS

This review underlines the need of specific psychotherapeutic and psychoeducational approaches for individuals at risk of Alzheimer's dementia, particularly in terms of an early intervention aiming at improving mental health and well-being. One challenge is the modification of psychotherapeutic techniques according to the different stages of cognitive decline in the course of AD, which is needed to be sensitive to the individual needs.

Modelling the Pan-European Economic Burden of Alzheimer's Disease

Background

Recent advances open the opportunity of altering the course of Alzheimer's disease (AD) through lifestyle-based modifications and novel therapies. Ensuring that society is investing limited budgets in the interventions that have the greatest potential to generate tangible impact will require tools to guide policymakers.

Objectives

To build on previous studies to develop an economic model that estimates the societal burden of AD and evaluates the potential impact of novel interventions in six large European countries.

Design

AD progression was modelled using a published Markov structure with a 40-year time horizon to estimate lifetime costs and life years in a cohort aged 65 years and above diagnosed with mild cognitive impairment due to AD (MCI-AD) in 2020. Demographic projections were utilized to estimate the prevalence of MCI-AD up to 2100, total corresponding costs and life years. The model allows a comparison of costs associated with the introduction of a hypothetical new disease-modifying therapy that slows disease progression between MCI-AD and all AD-Dementia stages as well as a 'delayed onset' scenario where disease progression is halted at the MCI-AD stage, potentially occurring, for example, through lifestyle-based modifications.

Results

The 2022 present value of total lifetime costs for this cohort moving through all disease stages is ~€1.2T. Approximately 80% of the present value of lifetime costs in our model are driven by informal care and non-medical direct costs. Our model suggests that a 25% and 50% reduction in disease progression compared to natural history could translate into a present value of cost savings of €33.7B and €72.7B. Halting MCI-AD progression for 3 years with no therapeutic effect thereafter resulted in a present value cost savings of €84.7B in savings.

Conclusions

Our data further suggest that early intervention via disease-modifying therapies or lifestyle-based modifications in AD could result in cost savings for society. Additionally, our findings reinforce the importance of accounting for the full value of innovative interventions, management and care paradigms, including their potential impact on direct, indirect and intangible costs impacting patients, their care partners and health and social care systems.

Robust Discovery of Mild Cognitive Impairment Subtypes and Their Risk of Alzheimer's Disease Conversion Using Unsupervised Machine Learning and Gaussian Mixture Modeling

BACKGROUND

Alzheimer's Disease (AD) is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. The ability to correctly predict the diagnosis of Alzheimer's disease in its earliest stages can help physicians make more informed clinical decisions on therapy plans.

OBJECTIVE

This study aimed to determine whether the unsupervised discovering of latent classes of subjects with Mild Cognitive Impairment (MCI) may be useful in finding different prodromal AD stages and/or subjects with a low MCI to AD conversion risk.

METHODS

Total 18 features relevant to the MCI to AD conversion process led to the identification of 681 subjects with early MCI. Subjects were divided into training (70%) and validation (30%) sets. Subjects from the training set were analyzed using consensus clustering, and Gaussian Mixture Models (GMM) were used to describe the latent classes. The discovered GMM predicted the latent class of the validation set. Finally, descriptive statistics, rates of conversion, and Odds Ratios (OR) were computed for each discovered class.

RESULTS

Through consensus clustering, we discovered three different clusters among MCI subjects. The three clusters were associated with low-risk (OR = 0.12, 95%CI = 0.04 to 0.3|), medium-risk (OR = 1.33, 95%CI = 0.75 to 2.37), and high-risk (OR = 3.02, 95%CI = 1.64 to 5.57) of converting from MCI to AD, with the high-risk and low-risk groups highly contrasting. Hence, prodromal AD subjects were present in only two clusters.

CONCLUSION

We successfully discovered three different latent classes among MCI subjects with varied risks of MCI-to-AD conversion through consensus clustering. Two of the discovered classes may represent two different prodromal presentations of Alzheimer´s disease.

Identifying relevant outcomes in the progression of Alzheimer's disease; what do patients and care partners want to know about prognosis?

BACKGROUND

Prognostic studies in the context of Alzheimer's disease (AD) mainly predicted time to dementia. However, it is questionable whether onset of dementia is the most relevant outcome along the AD disease trajectory from the perspective of patients and their care partners. Therefore, we aimed to identify the most relevant outcomes from the viewpoint of patients and care partners.

METHODS

We used a two-step, mixed-methods approach. As a first step we conducted four focus groups in the Netherlands to elicit a comprehensive list of outcomes considered important by patients (n = 12) and care partners (n = 14) in the prognosis of AD. The focus groups resulted in a list of 59 items, divided into five categories. Next, in an online European survey, we asked participants (n = 232; 99 patients, 133 care partners) to rate the importance of all 59 items (5-point Likert scale). As participants were likely to rate a large number of outcomes as "important" (4) or "very important" (5), we subsequently asked them to select the three items they considered most important.

RESULTS

The top-10 lists of items most frequently mentioned as "most important" by patients and care partners were merged into one core outcome list, comprising 13 items. Both patients and care partners selected outcomes from the category "cognition" most often, followed by items in the categories "functioning and dependency" and "physical health." No items from the category "behavior and neuropsychiatry" and "social environment" ended up in our core list of relevant outcomes.

CONCLUSION

We identified a core list of outcomes relevant to patients and care partner, and found that prognostic information related to cognitive decline, dependency, and physical health are considered most relevant by both patients and their care partners.

Exploring how triads of people living with dementia, carers and health care professionals function in dementia health care: A systematic qualitative review and thematic synthesis

BACKGROUND

Many qualitative studies report the post-diagnostic care experiences of carers and people living with dementia; however, this is not often accompanied by opportunities to hear the corresponding views of their health care professionals and how this triadic relationship functions. The aim of this review was to identify and thematically synthesize the experiences of health care services reported by people living with dementia, their carers and health care professionals.

METHODS

Medline, PsycINFO, Embase and CINAHL were searched from inception to 31 July 2019 for qualitative research including people living with dementia, carers and health care professionals. Data were coded and thematically synthesised using NVivo.

RESULTS

Of 10,045 search results, 29 papers relating to 27 studies were included in the final synthesis, including 261 people living with dementia, 444 carers and 530 health care professionals. Six themes emerged related to the functioning of a dementia care triad: (1) involving the person living with dementia, (2) establishing expectations of care and the roles of the members of the triad, (3) building trust, (4) effective communication, (5) continuity of care and (6) understanding the unique relationship dynamics within each triad.

DISCUSSION

The interactions and complexity of triadic dementia care relationships further our understanding of how to improve dementia care. Awareness of possible diverging attitudes highlights areas of necessary improvement and further research into facilitating engagement, such as when multiple professionals are involved or where there are mismatched expectations of the roles of triad members. In order to operate efficiently as a triad member, professionals should be aware of how pre-existing relations can influence the composition of a triad, encourage the involvement of the person living with dementia, clarify the expectations of all parties, establish trusting relationships and enable communication within the direct triad and beyond.

The Experience of Lived Time in People with Dementia: A Systematic Meta-Synthesis

INTRODUCTION

For people with dementia, lived time is important to understand, as the condition affects memory, perceptions of time, and life expectancy. The aim of this study was to locate, interpret, and synthesize the experience of lived time for people with dementia.

METHOD

This article presents a qualitative systematic meta-synthesis. The theoretical framework of lifeworlds by van Manen provided the context for the study. The Critical Appraisal Skills Programme criteria for qualitative studies were used to appraise the studies. Sixty-one qualitative research studies based on interviews with people with dementia were included in the review. The analysis followed the principles of interpretive synthesis.

RESULTS

Four categories were revealed: (1) rooted in the past - "I am the same as before"; (2) focussing on the present - "Nobody has tomorrow"; (3) thinking about the future - "What is going to happen to me?"; and (4) changes in the experience of self over time - "I used to…." The latent overall meaning was expressed as "being engaged with the dimensions of time."

DISCUSSION/CONCLUSION

The experience of lived time is an active and important one, enabling people to manage the dementia journey. Future work involving people with dementia should foreground the experience of lived time.

[Early detection of Alzheimer's disease and dementia prediction in patients with mild cognitive impairment : Summary of current recommendations]

Mild cognitive impairment (MCI) is characterized by cognitive deficits but essentially preserved competence in activities of daily living. It is a risk factor for the development of dementia and can reflect a prodromal predementia state of Alzheimer's disease (AD). The pathology of AD is defined by cerebral deposition of amyloid-beta-1-42 protein and aggregation of phosphorylated tau protein, which can be identified in vivo by biomarkers for these alterations. As a result of advances in the field of biomarker-based early detection of AD, it is possible to differentiate between MCI patients with and without a pathological AD condition and therefore, between patients with a low and those with a high risk for the development of dementia. At present there are no specific guideline recommendations in Germany for the diagnostic use of biomarkers in predementia detection of AD and for dementia risk assessment in patients with MCI. This article summarizes the current recommendations of a European expert consensus publication and a multidisciplinary working group of the Alzheimer's Association on the clinical application of cerebrospinal fluid (CSF) biomarkers for the diagnostics of AD in patients with MCI. If the clinical diagnostic criteria for MCI are fulfilled according to the medical history and neuropsychological testing, it is recommended to carry out further diagnostics (blood test, brain imaging) in order to more precisely define the differential diagnostic classification. Counseling on the potential benefits, limits and risks of biomarker testing for early AD detection and dementia risk prediction should always precede assessment of CSF biomarkers. Information about the individual risk of developing dementia has potential consequences for the psychological well-being and life planning; therefore, clinical follow-up visits are recommended.

[Development of a decision aid for participative advance planning for people with dementia and their relatives]

BACKGROUND

Patients with a diagnosis of dementia face various important social and health-related decisions. Due to the progression of the disease it seems crucial that patients try to deal with these decisions early in the course of the disease to have the opportunity to make decisions autonomously. Professional support can help to plan in advance according to the wishes and possibilities in an effective and individualized manner.

MATERIAL AND METHODS

The instrument was developed in a multiphase process based on advance care planning and shared decision-making. The prototype was pretested on 8 patient-relative dyads from a special outpatient department for early recognition and adapted as best as possible to their needs. Subsequently, in a pilot study the applicability of the decision aid was tested as an intervention in a further 19 patient-relative dyads with trained conversion attendants (diagnosis of Alzheimer's dementia or mixed form; mini mental state examination, MMSE (Mini-Mental-State-Test-Summenwert) >20 and <27).

RESULTS

The result was a written decision-making aid for people with early stage dementia and their relatives, which supports the decision-making process (health care proxy, advance directive, living and care, driving ability). The first results showed good acceptance and handling. Patients and relatives dealt with the individual topics to a high degree and found them to be highly relevant.

CONCLUSION

Despite positive feedback from the participants with respect to acceptance and applicability, there were major difficulties in recruiting. In the future, the systematic use of decision support as part of routine care could help to support the decision-making process in this patient group.

What next? Experiences of social support and signposting after a diagnosis of dementia

The experience of being diagnosed with dementia can be shocking. This may be compounded if individuals feel that there is a lack of signposting onto further avenues of support following diagnosis. This study, then, examines how social support is promoted in the diagnostic process. Using purposive sampling and a grounded theory approach, semi-structured interviews were conducted with 13 members of a dementia empowerment group in Northern Ireland, discussing both their experience of diagnosis and also their subsequent group membership. Respondents reported both positive and negative experiences of diagnosis. Feelings of shock and bewilderment accompanied this process. Only one was able to identify a direct link between a medical professional and referral to the empowerment group, others being referred by other health professionals or dementia navigators. The study indicates that, due to disorienting feelings, one diagnostic consultation is insufficient to explain both the diagnosis and offer follow-up support. Therefore, more explicit links to navigators or other services need to be made at the point of diagnosis to prioritise information regarding opportunities for social engagement for those being diagnosed.

What are the mechanisms that support healthcare professionals to adopt assisted decision-making practice? A rapid realist review

BACKGROUND

The United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) establishes a right to legal capacity for all people, including those with support needs. People with disabilities have a legal right to be given the appropriate supports to make informed decisions in all aspects of their lives, including health. In Ireland, the Assisted Decision-Making (Capacity) Act (2015) ratifies the Convention and has established a legal framework for Assisted Decision Making (ADM). The main provisions of the Act are not yet implemented. Codes of Practice to guide health and social care professionals are currently being developed. Internationally, concerns are expressed that ADM implementation is poorly understood. Using realist synthesis, this study aims to identify Programme Theory (PT) that will inform ADM implementation in healthcare.

METHODS

A Rapid Realist Review using collaborative methods was chosen to appraise relevant literature and engage knowledge users from Irish health and social care. The review was led by an expert panel of relevant stakeholders that developed the research question which asks, 'what mechanisms enable healthcare professionals to adopt ADM into practice?' To ensure the PT was inclusive of local contextual influences, five reference panels were conducted with healthcare professionals, family carers and people with dementia. PT was refined and tested iteratively through knowledge synthesis informed by forty-seven primary studies, reference panel discussions and expert panel refinement and consensus.

RESULTS

The review has developed an explanatory PT on ADM implementation in healthcare practice. The review identified four implementation domains as significant. These are Personalisation of Health & ADM Service Provision, Culture & Leadership, Environmental & Social Re-structuring and Education, Training & Enablement. Each domain is presented as an explanatory PT statement using realist convention that identifies context, mechanism and outcome configurations.

CONCLUSIONS

This realist review makes a unique contribution to this field. The PT can be applied by policymakers to inform intervention development and implementation strategy. It informs the imminent policy and practice developments in Ireland and has relevance for other worldwide healthcare systems dealing with similar legislative changes in line with UNCRPD.

What outcomes are important to patients with mild cognitive impairment or Alzheimer's disease, their caregivers, and health-care professionals? A systematic review

INTRODUCTION

Clinical trials involving patients with Alzheimer's disease (AD) continue to try to identify disease-modifying treatments. Although trials are designed to meet regulatory and registration requirements, many do not measure outcomes of the disease most relevant to key stakeholders.

METHODS

A systematic review sought research that elicited information from people with AD, their caregivers, and health-care professionals on which outcomes of the disease were important. Studies published in any language between 2008 and 2017 were included.

RESULTS

Participants in 34 studies described 32 outcomes of AD. These included clinical (memory, mental health), practical (ability to undertake activities of daily living, access to health information), and personal (desire for patient autonomy, maintenance of identity) outcomes of the disease.

DISCUSSION

Evidence elicited directly from the people most affected by AD reveals a range of disease outcomes that are relevant to them but are not commonly captured in clinical trials of new treatments.

The key factors for the engagement of primary stakeholders in decision-making for the future care of people with dementia living in the community: a systematic integrative review

BACKGROUND

Engagement of people with dementia who are living in the community, their family or carers, and healthcare professionals in decision-making related to their future care is an area yet to be explored in the literature. In particular, little is known about the factors most likely to underpin their engagement.

OBJECTIVES

To identify key factors for the engagement of the person with dementia living in the community, as well as their family or carer and their healthcare professionals in decision-making processes related to future care.

DESIGN

This is an integrative review guided by the PRISMA guidelines; the Mixed Methods Appraisal Tool was used to assess study quality. MEDLINE, PubMed, CINAHL, PsycINFO and Embase databases were searched for articles published from 2012 to 2018 that focused on people with dementia who live in the community, their family or carers, and community-based healthcare professionals.

RESULTS

Twenty articles were included in the review, and six key factors were identified through thematic analysis: knowledge and understanding of dementia and decision-making for the future, valuing decision-making for the future, healthcare professionals' communication skills, timing of initiating conversations, relationship quality, and orientation to the future.

CONCLUSION

This review identifies the six key factors required for the engagement of the three primary key stakeholders in decision-making about the future care of people with dementia. It also situates the factors within the complex context in which people with dementia, their family or carers, and healthcare professionals typically find themselves.

Balancing the struggle to live with dementia: a systematic meta-synthesis of coping

BACKGROUND

People with dementia describe experiences of loss that threaten their autonomy and ability to contribute to society. They often have difficulties with orientation, loss of roll function, and fear about the future, and need help from others. An increasing body of literature also focuses on how people with dementia search for meaning and maintaining of quality to life, and how they find strategies to live with dementia. A review of the scientific literature on coping and dementia is warranted and can help to advice and inform healthcare personnel and decision makers on how they can support and plan for appropriate healthcare services for people with dementia. The aim of this systematic meta-synthesis was therefore to interpret and synthesize knowledge regarding people with dementia's experience of coping.

METHODS

We conducted a systematic, computerised search of Medline, Embase, Cinahl Complete, PsycINFO and Age Line combining MeSH terms and text words for different types of dementia with different descriptions of experience. Studies comprised 1) a sample of people with dementia, 2) a qualitative interview as a research method and 3) a description of experiences of coping were included. The search resulted in 7129 articles, of which 163 were read in full text, 80 were excluded due to the exclusion criteria or low quality according. The analysis was conducted in line with qualitative content analyses.

RESULTS

This interpretative qualitative meta-synthesis included 74 articles of good quality encompassing interviews with 955 persons with dementia. The material revealed two main resources of coping: (1) Humour and (2) Practical and emotional support, and four overall strategies in which people with dementia cope with the challenges they experience: (1) Keep going and holding on to life as usual; (2) Adapting and adjusting to the demands from the situation; (3) Accepting the situation; and (4) Avoiding the situation A comprehensive understanding of the categories led to the latent theme: Balancing the struggle of living with dementia.

CONCLUSION

This meta-synthesis indicates that people with dementia cope in different ways and using several parallel strategies. This insight is essential in dementia care to facilitate a supportive environment.

Do people with early stage dementia experience Prescribed Disengagement®? A systematic review of qualitative studies

ABSTRACTBackground:Prescribed Disengagement® is the description of the post-diagnostic advice given to people after a diagnosis of dementia, which explicitly or implicitly suggests that the person should be slowing down or pulling back from activities. This results in isolation, loss of hope, self-esteem and self-identity, and threatens social health. This study aims to review whether Prescribed Disengagement® can be identified in the literature on subjective experiences of people living with early dementia.

METHODS

A systematic search was performed. Inclusion criteria were original empirical qualitative studies published in English that addressed the subjective experiences of living with a diagnosis of objectively defined early dementia. Thematic synthesis was undertaken.

RESULTS

Thirty-five papers involving 373 participants were included. Following a diagnosis, people with dementia struggled with self-identity, independence, control and status, activities, stigma, and how to view the future. Reactions in these areas ranged from active and positive to negative and passive. Many studies reported participants' dissatisfaction with the way the diagnosis was communicated. There was insufficient information provided about dementia and limited treatments and support offered. The diagnosis process and post-diagnostic support may have contributed to disempowerment of the person with dementia, made it more difficult to accept the diagnosis, and exacerbated negative views and self-stigma around dementia.

CONCLUSIONS

These results do not support the idea of Prescribed Disengagement®. However disengagement may have been implied during the diagnosis process and post-diagnostic support. Research is needed on how to improve the communication of dementia diagnosis and support people to live well post-diagnosis.

Advance directives for future dementia can be modified by a brief video presentation on dementia care: An experimental study

OBJECTIVES

To investigate whether life-sustaining measures in medical emergency situations are less accepted for an anticipated own future of living with dementia, and to test whether a resource-oriented, in contrast to a deficit-oriented video about the same demented person, would increase the acceptance of such life-saving measures.

DESIGN

Experimental study conducted between September 2012 and February 2013.

SETTING

Community dwelling female volunteers living in the region of Bonn, Germany.

PARTICIPANTS

278 women aged 19 to 89 (mean age 53.4 years).

INTERVENTION

Presentation of a video on dementia care focusing either on the deficits of a demented woman (negative framing), or focusing on the remaining resources (positive framing) of the same patient.

MAIN OUTCOME MEASURES

Approval of life-sustaining treatments in five critical medical scenarios under the assumption of having comorbid dementia, before and after the presentation of the brief videos on care.

RESULTS

At baseline, the acceptance of life-sustaining measures in critical medical situations was significantly lower in subjects anticipating their own future life with dementia. Participants watching the resource-oriented film on living with dementia had significantly higher post-film acceptance rates compared to those watching the deficit-oriented negatively framed film. This effect particularly emerges if brief and efficient life-saving interventions with a high likelihood of physical recovery are available (eg, antibiotic treatment for pneumonia).

CONCLUSIONS

Anticipated decisions regarding life-sustaining measures are negatively influenced by the subjective imagination of living with dementia, which might be shaped by common, unquestioned stereotypes. This bias can be reduced by providing audio-visual information on living with dementia which is not only centred around cognitive and functional losses but also focuses on remaining resources and the apparent quality of life. This is particularly true if the medical threat can be treated efficiently. These findings have implications for the practice of formulating, revising, and supporting advance directives.

The Effect of the Association between Donepezil and Choline Alphoscerate on Behavioral Disturbances in Alzheimer's Disease: Interim Results of the ASCOMALVA Trial

BACKGROUND

Behavioral and psychological symptoms of dementia (BPSD) are a group of psychological reactions, psychiatric symptoms, and behaviors commonly found in Alzheimer's disease (AD). Four clusters of BPSD have been described: mood disorders (depression, anxiety, and apathy), psychotic symptoms (delusions and hallucinations), aberrant motor behaviors (pacing, wandering, and other purposeless behaviors), and inappropriate behaviors (agitation, disinhibition, and euphoria). Most of them are attributed to acetylcholine deficiency.

OBJECTIVE

To evaluate if a higher amount of acetylcholine obtained by associating donepezil and choline alphoscerate might have a favorable effect on BPSD.

METHODS

BPSD were measured at baseline and after 24 months in 113 mild/moderate AD patients, included in the double-blind randomized trial ASCOMALVA, by the Neuropsychiatric Inventory (NPI). Two matched groups were compared: group A treated with donepezil (10 mg/day) plus choline alphoscerate (1200 mg/day), and group B treated with donepezil (10 mg/day) plus placebo.

RESULTS

Data of NPI revealed a significant decrease of BPSD severity and distress of the caregiver in patients of group A compared with group B. Mood disorders (depression, anxiety and apathy) were significantly decreased in subjects treated with donepezil and choline alphoscerate, while their severity and frequency was increased in the other group.

CONCLUSIONS

Patients treated with donepezil plus choline alphoscerate showed a lower level of behavioral disturbances than subjects treated with donepezil only, suggesting that the association can have beneficial effects.

The experience of lived space in persons with dementia: a systematic meta-synthesis

BACKGROUND

Identifying how persons with dementia experience lived space is important for enabling supportive living environments and creating communities that compensate for the fading capabilities of these persons. Several single studies have explored this topic; however, few studies have attempted to explicitly review and synthesize this research literature. The aim of this systematic meta-synthesis was therefore to interpret and synthesize knowledge regarding persons with dementia's experience of space.

METHODS

A systematic, computerized search of AgeLine, CINAHL Complete, Embase, Medline and PsycINFO was conducted using a search strategy that combined MeSH terms and text words for different types of dementia with different descriptions of experience. Studies with 1) a sample of persons with dementia, 2) qualitative interviews as a research method and 3) a description of experiences of lived space were included. The search resulted in 1386 articles, of which 136 were identified as eligible and were read and assessed using the CASP criteria. The analysis was inspired by qualitative content analyses.

RESULTS

This interpretative qualitative meta-synthesis included 45 articles encompassing interviews with 672 persons with dementia. The analysis showed that living in one's own home and living in long-term care established different settings and posed diverse challenges for the experience of lived space in persons with dementia. The material revealed four main categories that described the experience of lived space: (1) belonging; (2) meaningfulness; (3) safety and security; and (4) autonomy. It showed how persons with dementia experienced a reduction in their lived space due to the progression of dementia. A comprehensive understanding of the categories led to the latent theme: "Living with dementia is like living in a space where the walls keep closing in".

CONCLUSION

This meta-synthesis reveals a process whereby lived space gradually becomes smaller for persons with dementia. This underscores the importance of being aware of the experiences of persons with dementia and the spatial dimensions of their life-world. To sustain person-centred care and support the preservation of continuity and identity, one must acknowledge not only the physical and social environment but also space as an existential experience for persons with dementia.

The Experience of Relations in Persons with Dementia: A Systematic Meta-Synthesis

BACKGROUND

Dementia influences a person's experience of social relationships, as described in several studies. In this systematic meta-synthesis of qualitative studies, we aim to interpret and synthesize the experiences of persons with dementias and their relations with others.

SUMMARY

Living with dementia changes life, leading to new social roles and different social statuses. Persons with dementia experience being disconnected and dependent on others, feeling like being a burden, and being a person who is treated in paternalistic ways. Family, friends and others with dementia might play significant roles in their ability to maintain a meaningful life. Key Messages: Three categories emerged from the data, change in life, change in relations, and maintenance of meaningful aspects in life; these categories are intertwined and essential in sustaining a lifeline for persons with dementia. The comprehensive meaning of the material is understood as the expression: Living a meaningful life in relational changes.

Inventory of Overburden in Alzheimer's Patient Family Caregivers with no Specialized Training

Background/Objective: Alzheimer-type dementia is one of the most frequent causes of dependence in an aging population, which combines with a considerable demand for care. Furthermore, when the caregiver is a family member or person without specialized training, such care impacts on that person's health. The Inventory of Overburden in Alzheimer's Patient Family Caregivers with no Specialized Training (IPSO-CA24) was designed to find out the needs of these caregivers and evaluate the caregiver's burden or distress. Method: The psychometric properties of the questionnaire were analyzed (in a reliability analysis, exploratory factor analysis and confirmatory analysis) based on the responses of 255 caregivers. Results: The factor analyses showed a six-factor structure (Reaction to diagnosis, Physical health, Psychological symptomatology (caretaker), Behavioral symptomatology (patient), Knowledge of the illness, and Level of dependence) explaining 66.52% of the total variance with a reliability of .75 to .93. Support was also found for its convergent validity. Conclusions: The IPSO-CA24 responds to the need for an instrument enabling multidimensional evaluation of the burden on the family caregiver without specialized training.

Driving in Early-Stage Alzheimer's Disease: An Integrative Review of the Literature

One of the most difficult decisions for individuals with Alzheimer's disease (AD) is when to stop driving. Because driving is a fundamental activity linked to socialization, independent functioning, and well-being, making the decision to stop driving is not easy. Cognitive decline in older adults can lead to getting lost while driving, difficulty detecting and avoiding hazards, as well as increased errors while driving due to compromised judgment and difficulty in making decisions. The purpose of the current literature review was to synthesize evidence regarding how individuals with early-stage AD, their families, and providers make determinations about driving safety, interventions to increase driving safety, and methods to assist cessation and coping for individuals with early-stage AD. The evidence shows that changes in driving ability start early and progress throughout the trajectory of AD. Some individuals with mild cognitive impairment or early-stage AD may be safe to drive for a period of time. Support groups aimed at helping with the transition have been shown to be helpful for individuals who stop driving. Research and practice must support interventions to help individuals maintain safety while driving, as well as cope with driving cessation. [Res Gerontol Nurs. 2017; 10(2):86-100.].

Efficient synthesis of longer Aβ peptides via removable backbone modification

This paper describes a new method for the efficient chemical synthesis of longer Aβ peptides with the combination of the RBM strategy and native chemical ligation.
