Professional caregivers' knowledge, beliefs and attitudes about awareness in advanced dementia: a systematic review of qualitative studies

[Conscience des déficits dans le cadre de la maladie d'Alzheimer : représentations et vécu des professionnels soignants]

La qualité des soins apportés aux personnes vivant avec la maladie d'Alzheimer (MA) dépend en partie de la capacité des professionnels à déterminer le degré de conscience de la maladie chez les patients. La présente recherche s'est intéressée aux représentations des soignants concernant la conscience des troubles chez les résidents d'établissements de soins de longue durée présentant un diagnostic de MA. Le pouvoir prédicteur de l'anosognosie sur le fardeau soignant a également été examiné. L'anosognosie des troubles de la construction (r = 0,40, p = 0,0164) et de l'initiation (r = 0,32, p = 0,052) était corrélée au fardeau soignant. Les professionnels se représentaient les résidents comme ayant une conscience altérée de leurs capacités, même en l'absence d'anosognosie. Les scores réels d'anosognosie ne prédisaient pas les estimations soignantes, hormis le score global sous forme de tendance (χ2 = 3,38, p = 0,066). Les soignants surestimaient pourtant les performances cognitives des résidents, telles que mesurées au moyen du protocole Misawareness (prédictions aidants/performances réelles : DC = 12,32, p < 0,0001).

Proposing a communication module to enhance dental students' attitudes towards people with dementia: Phase 1 of a curriculum revision study

INTRODUCTION

The number of mentally altered patients a dentist meets in practice is increasing and interaction with them can be very challenging. As a baseline for an interventional study, we want to assess the attitude of dental students and identify areas of improvement in patient communication. This work compares the attitude of dental students towards people suffering from dementia to the attitudes of trained medical caregivers and the general population. Our aim is to use the results to assess the need for training in communicating with mentally altered patients.

MATERIALS AND METHODS

Fourth-year dental students attended two lectures on dementia given by a psychiatrist as part of the geriatric dentistry lecture and were questioned afterwards using the Dementia Attitude Scale. In 2016 and 2017, 73 students at the University of Greifswald were interviewed. The response rate was 84%. Using a factor analysis, the Dementia Attitude Scale's validated questions were interpreted and compared with data from nursing staff from Switzerland and the USA.

RESULTS

The factor analysis of the data showed the same two-factor loadings as the comparative groups, and that dental students' attitude is more comparable to the general population than to medically trained nursing staff.

CONCLUSION

Given the results, we conclude that the implementation of a communication module can serve in improving the attitude of dental students towards patients with dementia.

Lucidity in the Deeply Forgetful: A Scoping Review

Background

Even in severe states of Alzheimer's disease and related dementias (ADRD), accounts of an unexpected or paradoxical return of awareness and lucidity have been reported in some patients, documented formally, and studied.

Objective

A scoping review was undertaken to survey the literature on the topic.

Methods

Five databases were searched using pertinent search terms. Results were deduplicated and subsequently screened by title and abstract for relevance. Remaining reports were read and included or excluded using specific inclusion criteria. 30 results consisted of a mix of perspective papers, case reports, qualitative surveys of caregivers, law journal comments, and mechanistic speculation.

Results

An equal mix of primary and secondary research was identified.

Conclusions

The papers collected in this review provide a valuable methodological outline for researching the topic of lucid episodes in ADRD. The verified legitimacy and simultaneous inexplicability of these events promote philosophical discussion, mechanistic investigations, and sorely needed research in the field of ADRD.

Physical Therapists' and Physical Therapist Students' Experiences and Views on the Provision of Physical Therapy Services to People With Dementia: A Scoping Review

BACKGROUND AND PURPOSE

Physical therapists (PTs) require specialized education and training to increase the capacity and competence of the dementia care workforce. Four areas of critical dementia workforce education and training gaps that apply to the physical therapy profession have been identified, including recruitment/retention, financing and cost of training, interprofessional education, and translation/implementation of effective dementia care. A critical step in developing effective training programs and educational curricula is to understand PTs' and PT students' experiences and views on working with people with dementia (PwD). Therefore, the purpose of this scoping review was to examine the extent and types of evidence that explore the experiences and views of PTs and PT students on the provision of physical therapy services to PwD.

METHODS

The Cochrane Database of Systematic Reviews, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsychINFO, ERIC, PEDro, Web of Science, and Medline databases and sources of gray literature were searched for sources of evidence that met the inclusion criteria of the review protocol. The literature was mapped according to author, participant role, setting, publication type, study design, study aim, key findings, and dementia workforce training gaps addressed.

RESULTS AND DISCUSSION

A total of 552 sources of evidence were screened for eligibility, and 16 studies were selected for inclusion. Twelve studies included PTs as participants, and 5 included PT students. Included sources explored PTs' experiences, behaviors, knowledge, attitudes, and confidence in working with PwD and the influence of educational, organizational, and other factors on these domains. Challenges to and strategies for delivering effective care to PwD were examined in multiple sources. The 4 areas of critical dementia workforce education and training gaps were each addressed by at least 1 of the included studies.

CONCLUSIONS

The current body of literature identifies several gaps in both research and education that need to be addressed before our profession is truly prepared to effectively manage this challenging population of patients with specialized needs.

Resilience and caregiving ability among caregivers of people with stroke: The mediating role of uncertainty in illness

BACKGROUND

In China, stroke survivors are usually cared for by their family members. However, the caregiving ability of these informal caregivers remain inadequate during the hospitalization of their family members following a sudden onset of a stroke, and this sudden need for care overwhelms caregivers even after the hospital discharge. Therefore, research is required to identify predictors of caregiving ability that could be targeted in future interventions aimed at improving caregiving skills and reducing the burden on caregivers who care for stroke survivors.

MATERIALS AND METHODS

From August 2019 to February 2020, stroke survivors were hospitalized for the first time, and their family caregivers were registered via convenience sampling. Caregiver demographic information, resilience status, uncertainty in illness, caregiving ability, and patients' severity of stroke were measured using standardized questionnaires. Structural equation modeling was used to test the proposed model, where caregiver resilience and stroke severity predicted caregiving ability directly, and uncertainty in illness mediated the association between caregiver resilience and caregiving ability.

RESULTS

A total of 306 dyads were included in the study. The tested model fit the data well (χ² = 118.2, df = 64, RMSEA = 0.053, CFI = 0.946, TLI = 0.923). Statistically significant pathways linked caregivers' resilience status to uncertainty in illness (β = -0.558, S.E. = 0.022, P < 0.01), caregivers' resilience to the status of caregiving ability (β = -0.269, S.E. = 0.013, P < 0.01) and caregivers' uncertainty about the illness to caregiving ability (β = 0.687, S.E. = 0.051, P < 0.01). We also found that caregivers' uncertainty in illness mediated the association between caregivers' resilience and caregiving ability (β = -0.384, S.E. = 0.061, P < 0.01).

CONCLUSIONS

Our structural equation modeling result identified resilience and uncertainty about the illness as predictors of the caregiving ability of informal family caregivers who suffered from care burdens. Supporting family caregivers to build their resilience and reduce illness uncertainty may improve caregiving for stroke survivors.

Do you look for information about dementia? Knowledge of cognitive impairment in older people among their relatives

Relatives and caregivers receive little information and have poor knowledge about cognitive impairment and dementia.

Understanding Alzheimer's disease as a disorder of consciousness

People with Alzheimer's disease (AD) demonstrate a range of alterations in consciousness. Changes in awareness of cognitive deficit, self-awareness, and introspection are seen early in AD, and dysfunction of awareness and arousal progresses with increasing disease severity. However, heterogeneity of deficits between individuals and a lack of empirical studies in people with severe dementia highlight the importance of identifying and applying biomarkers of awareness in AD. Impairments of awareness in AD are associated with neuropathology in regions that overlap with proposed neural correlates of consciousness. Recent developments in consciousness science provide theoretical frameworks and experimental approaches to help further understand the conscious experience of people with AD. Recognition of AD as a disorder of consciousness is overdue, and important to both understand the lived experience of people with AD and to improve care.

The associations between social, built and geophysical environment and age-specific dementia mortality among older adults in a high-density Asian city

Background

Although socio-environmental factors which may affect dementia have widely been studied, the mortality of dementia and socio-environmental relationships among older adults have seldom been discussed.

Method

A retrospective, observational study based on territory-wide register-based data was conducted to evaluate the relationships of four individual-level social measures, two community-level social measures, six short-term (temporally varying) environmental measures, and four long-term (spatially varying) environmental measures with dementia mortality among older adults in a high-density Asian city (Hong Kong), for the following decedents: (1) all deaths: age >= 65, (2) “old-old”: age > = 85, (3) “mid-old”: aged 75–84, and (4) “young-old”: aged 65–74.

Results

This study identified 5438 deaths (3771 old-old; 1439 mid-old; 228 young-old) from dementia out of 228,600 all-cause deaths among older adults in Hong Kong between 2007 and 2014. Generally, regional air pollution, being unmarried or female, older age, and daily O₃ were associated with higher dementia mortality, while more urban compactness and greenness were linked to lower dementia mortality among older adults. Specifically, being unmarried and the age effect were associated with higher dementia mortality among the “old-old”, “mid-old” and “young-old”. Regional air pollution was linked to increased dementia mortality, while urban compactness and greenness were associated with lower dementia mortality among the “old-old” and “mid-old”. Higher daily O₃ had higher dementia mortality, while districts with a greater percentage of residents whose native language is not Cantonese were linked to lower dementia mortality among the “old-old”. Economic inactivity was associated with increased dementia mortality among the “young-old”. Gender effect varied by age.

Conclusion

The difference in strengths of association of various factors with dementia mortality among different age groups implies the need for a comprehensive framework for community health planning. In particular, strategies for air quality control, usage of greenspace and social space, and activity engagement to reduce vulnerability at all ages are warranted.
