Awareness of social and emotional functioning in people with early-stage dementia and implications for carers

Do I Have Symptoms of Dementia: A Discursive Study of Awareness and Shame Among People With Advanced Dementia

BACKGROUND AND OBJECTIVES

This study explores the narrated experiences of individuals with advanced stages of late-onset dementia, focusing on their diagnosis awareness. Such framing is motivated by 2 reasons. Firstly, there is a lack of consensus regarding the prevalence of anosognosia among people with dementia. Secondly, research on anosognosia often neglects to address the important issues of shame and stigma associated with receiving a dementia diagnosis.

RESEARCH DESIGN AND METHODS

For this qualitative study, a total of 27 participants ranging in age from 66 to 94 were involved. The data collected were analyzed using textual-oriented discourse analysis.

RESULTS

Our findings indicated that individuals with dementia struggled to comprehend the medical terminology used to describe their experiences within biomedical standards. The interviewees utilized 5 negative discourses on dementia, which shaped their attitudes toward the condition and people diagnosed with it. These discourses depicted dementia as an illness, negative aging, a devaluation, a burden, and a life tragedy. Moreover, study participants did not outright reject the diagnosis but rather negotiated its acceptance within the context of shame associated with dementia.

DISCUSSION AND IMPLICATIONS

The concept of anosognosia can serve as a mechanism of social control and stigmatization of people with dementia within the dominant biomedical discourse.

"WOOP is my safe haven": A qualitative feasibility and acceptability study of the Wish Outcome Obstacle Plan (WOOP) intervention for spouses of people living with early-stage dementia

OBJECTIVES

As symptoms emerge and worsen in people living with dementia, their spouses can benefit from behavioral interventions to support their adjustment as a care partner. The Wish Outcome Obstacle Plan (WOOP) intervention improves the well-being of spouses of people living with dementia early in the disease course, but intervention mechanisms and opportunities for improvement are unclear. The present study gave voice to spouses who participated in a trial of WOOP, describing how WOOP was incorporated into their lives and how it could be improved for future implementation.

METHOD

For this qualitative study, we conducted longitudinal semi-structured interviews among 21 spouses of people living with dementia (three interviews over three months; 63 interviews total). Codebook thematic analysis was performed.

RESULTS

Three meta-themes were derived: (1) assessing baseline strengths and limitations of WOOP, (2) learning from experience, and (3) fine-tuning and sustaining WOOP. Participants described how WOOP addressed their interpersonal and emotional stressors, their responses to behaviors of the person living with dementia, and their relationship quality. Considerations for future intervention delivery (e.g., solo vs. in group settings) and instructions (e.g., encouraging writing vs. thinking through the four steps of WOOP) were identified as areas of improvement.

CONCLUSIONS

WOOP was described as a practical, feasible, and desirable intervention for spouses at the early stages of their partner's dementia. Participants made WOOP easier to incorporate in their everyday lives by adapting the design into a mental exercise that they used as needed. Suggestions from participants specified how to make the everyday use of WOOP more feasible, sustainable, and applicable in a variety of contexts.

[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).

Awareness of Social Functioning in People with Dementia and Its Association with Dementia Severity: Multi-Center Cross-Sectional Study

Background

People with dementia commonly have impaired social functioning and may not recognize this. This lack of awareness may result in worse outcomes for the person and their family carers.

Objective

We aimed to characterize awareness of social functioning in dementia and describe its association with dementia severity.

Methods

Multi-center cross-sectional study of people aged >65 years with dementia and family informants recruited from Germany, Japan and the United Kingdom. We used the Social Functioning in Dementia (SF-DEM) scale, assessing "spending time with other people" (domain 1), "communicating with other people" (domain 2), and "sensitivity to other people" (domain 3), and calculated lack of awareness into social functioning as the discrepancy between patient and informant ratings.

Results

108 participants with dementia (50.9% women), mean age = 78.9 years, and mean MMSE score = 22.7. Patient and informant domain 1 ratings did not differ, but patient-rating was higher than carers for domain 2 (11.2 versus 10.1; p = 0.003) and domain 3 (9.7 versus 8.1; p < 0.001). Sixty people with dementia overestimated their overall social functioning, 30 underestimated, and 18 gave ratings congruent with their informant. Performance on the MMSE and its sub-domains was not associated with SF-DEM discrepancy score.

Conclusions

We found that awareness of social functioning in dementia was a multidimensional concept, which varies according to subdomains of social functioning. Clinicians should help family members understand and adapt by explaining their relative with dementia's lack of awareness about aspects of their social functioning.

Dyadic influences on awareness of condition in people with dementia: findings from the IDEAL cohort

Introduction

The discrepancy between caregiver-ratings and self-ratings of abilities is commonly used to assess awareness in people with dementia. We investigated the contribution of caregiver and dyadic characteristics to the difference in perspective between caregiver-informants and people with dementia about difficulties experienced, when considering awareness of condition.

Methods

We conducted exploratory cross-sectional analyses using data from the IDEAL cohort. Participants were 1,038 community-dwelling people with mild-to-moderate dementia, and coresident spouse/partner caregivers. The Representations and Adjustment to Dementia Index (RADIX) checklist reporting difficulties commonly experienced in dementia was completed by 960 caregiver-informants and 989 people with dementia. Difference in scores was calculated for 916 dyads. Demographic information, cognition, informant-rated functional ability and neuropsychiatric symptoms were recorded for the person with dementia. Self-reported data were collected on mood, comorbidity, religion, importance of religion, relationship quality, and caregiver stress.

Results

For most dyads, caregivers reported more RADIX difficulties than people with dementia. Caregiver RADIX ratings were more closely associated with informant-rated functional ability and neuropsychiatric symptoms than with cognition. More RADIX difficulties and higher stress were reported by female caregivers. Greater RADIX difference was associated with more caregiver stress, and older age but less depression in people with dementia.

Conclusion

Few dyadic characteristics were important, but caregiver stress was higher where caregivers reported more RADIX difficulties and/or the difference in perspective was greater, whereas partners with dementia reported better mood. In addition to offering information about awareness of condition, the caregiver rating and difference in perspectives could indicate where more support is needed.

A Longitudinal Evaluation of the Pattern of Social Cognition Impairment in Brazilians With Alzheimer's Disease

BACKGROUND

Social cognition (SC) impairments contribute to the dependence of people with Alzheimer disease (AD), influencing their functional disability and the burden on family members and caregivers. Our objective was to longitudinally investigate the relationship between SC and cognitive and clinical variables in persons with AD and their caregivers. We also evaluated the different SC predictors from 3 perspectives: people with AD, caregivers of people with AD, and discrepancy analysis.

METHODS

In all, 137 dyads (people with AD and their caregivers) underwent 2 assessments: at baseline (M1) and after 1 year (M2). During follow-up, 58 dyads were excluded, and the study was thus concluded with 79.

RESULTS

Longitudinal analysis of the people with AD showed that while some cognitive functions declined (which is consistent with disease progression), SC impairments showed a more stable pattern. Another interesting result was related to SC predictors. For people with AD, SC was associated with cognition at both time points. For caregivers, besides cognition, other predictors included reduced functional abilities and quality of life in people with AD. These results are consistent with the discrepancy predictors.

CONCLUSION

The stable pattern in SC functioning over 12 months in AD suggests that this neurocognitive domain may be influenced more by emotional processing than by cognitive impairment. In addition, the SC predictors showed that the investigation of different points of view enables a more global understanding, contributing to better and more targeted treatment for the patient.

What Are the Neural Correlates of Impaired Awareness of Social Cognition and Function in Dementia? A Systematic Review

Deficits in social cognition and function are characteristic of dementia, commonly accompanied by a loss of awareness of the presence or extent of these deficits. This lack of awareness can impair social relationships, increase patients' and carers' burden, and contribute to increased rates of institutionalization. Despite clinical importance, neural correlates of this complex phenomenon remain unclear. We conducted a systematic search of five electronic databases to identify functional and structural neuroimaging studies investigating the neural correlates of impaired awareness of social cognition and function in any dementia type. We rated study quality and conducted a narrative synthesis of the results of the eight studies that met the predefined eligibility criteria. Across these studies, deficits in awareness of impairments in social cognition and function were associated with structural or functional abnormalities in the frontal pole, orbitofrontal cortex, temporal pole, middle temporal gyrus, inferior temporal gyrus, fusiform gyrus, amygdala, hippocampus, parahippocampal gyrus, and insula. Several identified regions overlap with established neural correlates of social cognition. More research is needed to understand awareness of social cognition and function and how this becomes impaired in dementia to improve neuroscientific understanding, aid the identification of this problematic symptom, and target interventions to reduce burden and improve care.

Trajectories of socio-emotional functioning in early-stage dementia: implications for the individual with dementia and their family carer

BACKGROUND AND OBJECTIVES

Changes in socio-emotional functioning in people living with dementia (PLWD) are common; however, little is known about the broader effects these may have on wellbeing. This study examined socio-emotional functioning over time and associations with the wellbeing of PLWD and their family carers.

METHOD

One hundred and one individuals with a diagnosis of dementia and their respective carers completed the Social Emotional Questionnaire (assessing emotion recognition, empathy, social relationships and social behaviour) alongside measures of dementia severity, cognition, mood, stress, and relationship quality. Sixty-six dyads were reassessed on the same measures at 12 months post-baseline, and 51 dyads again at 20 months post-baseline.

RESULTS

When rated by the PLWD, there was no change in socio-emotional functioning over time; however, carers reported a significant decline over time. For both carers and the PLWD, poorer wellbeing measures were indicative of worse socio-emotional functioning at Time 1, though only dementia type, quality of life and relationship quality impacted upon the trajectory of socio-emotional decline over time.

CONCLUSIONS

Changes in social and emotional functioning are evident early in the course of dementia and worsen within 20 months. Both carer characteristics and those of the PWLD affected reporting of social and emotional functioning. These data are useful for guiding the provision of appropriate education and care.

Cross-disorder and disorder-specific deficits in social functioning among schizophrenia and alzheimer's disease patients

Background

Social functioning is often impaired in schizophrenia (SZ) and Alzheimer’s disease (AD). However, commonalities and differences in social dysfunction among these patient groups remain elusive.

Materials and methods

Using data from the PRISM study, behavioral (all subscales and total score of the Social Functioning Scale) and affective (perceived social disability and loneliness) indicators of social functioning were measured in patients with SZ (N = 56), probable AD (N = 50) and age-matched healthy controls groups (HC, N = 29 and N = 28). We examined to what extent social functioning differed between disease and age-matched HC groups, as well as between patient groups. Furthermore, we examined how severity of disease and mood were correlated with social functioning, irrespective of diagnosis.

Results

As compared to HC, both behavioral and affective social functioning seemed impaired in SZ patients (Cohen’s d’s 0.81–1.69), whereas AD patients mainly showed impaired behavioral social function (Cohen’s d’s 0.65–1.14). While behavioral indices of social functioning were similar across patient groups, SZ patients reported more perceived social disability than AD patients (Cohen’s d’s 0.65). Across patient groups, positive mood, lower depression and anxiety levels were strong determinants of better social functioning (p’s <0.001), even more so than severity of disease.

Conclusions

AD and SZ patients both exhibit poor social functioning in comparison to age- and sex matched HC participants. Social dysfunction in SZ patients may be more severe than in AD patients, though this may be due to underreporting by AD patients. Across patients, social functioning appeared as more influenced by mood states than by severity of disease.

The Relationship Between Decision-making Capacity and the Domains of Awareness in Alzheimer Disease

People with Alzheimer dementia (PwAD) who are aware of their overall cognitive function and diagnosis are more likely to be judged competent in decision-making capacity. Therefore, we aimed to investigate the relationship between decision-making capacity and the different domains of awareness and the relationship between decision-making capacity and the cognitive and clinical impairment of the PwAD. Using a cross-sectional design, we included 121 PwAD and their caregivers. Awareness was assessed across domains, including cognitive functioning and health condition, functional activity impairments, emotional state, social functioning, and interpersonal relationships. The MacArthur Competence Assessment Tool for Treatment was adopted to gather information about decision-making abilities. We found that decision-making capacity is related to the cognitive and functional domains of awareness and relatively independent of the emotional functioning and the relationship domains. Our finding highlighted that PwAD who are unaware of the disease or the cognitive and functional impairments might be unlikely to appreciate the personal benefits of a proposed health treatment or to understand and judge the personal consequences of a decision accurately.

Assessment of Social Behavior Using a Passive Monitoring App in Cognitively Normal and Cognitive Impaired Older Adults: an Observational Study (Preprint)

Background

In people with cognitive impairment, loss of social interactions has a major impact on well-being. Therefore, patients would benefit from early detection of symptoms of social withdrawal. Current measurement techniques such as questionnaires are subjective and rely on recall, in contradiction to smartphone apps, which measure social behavior passively and objectively.

Objective

This study uses the remote monitoring smartphone app Behapp to assess social behavior, and aims to investigate (1) the association between social behavior, demographic characteristics, and neuropsychiatric symptoms in cognitively normal (CN) older adults, and (2) if social behavior is altered in cognitively impaired (CI) participants. In addition, we explored in a subset of individuals the association between Behapp outcomes and neuropsychiatric symptoms.

Methods

CN, subjective cognitive decline (SCD), and CI older adults installed the Behapp app on their own Android smartphone for 7 to 42 days. CI participants had a clinical diagnosis of mild cognitive impairment (MCI) or Alzheimer-type dementia. The app continuously measured communication events, app use and location. Neuropsychiatric Inventory (NPI) total scores were available for 20 SCD and 22 CI participants. Linear models were used to assess group differences on Behapp outcomes and to assess the association of Behapp outcomes with the NPI.

Results

We included CN (n=209), SCD (n=55) and CI (n=22) participants. Older cognitively normal participants called less frequently and made less use of apps (P<.05). No sex effects were found. Compared to the CN and SCD groups, CI individuals called less unique contacts (β=–0.7 [SE 0.29], P=.049) and contacted the same contacts relatively more often (β=0.8 [SE 0.25], P=.004). They also made less use of apps (β=–0.83 [SE 0.25], P=.004). Higher total NPI scores were associated with further traveling (β=0.042 [SE 0.015], P=.03).

Conclusions

CI individuals show reduced social activity, especially those activities that are related to repeated and unique behavior, as measured by the smartphone app Behapp. Neuropsychiatric symptoms seemed only marginally associated with social behavior as measured with Behapp. This research shows that the Behapp app is able to objectively and passively measure altered social behavior in a cognitively impaired population.

Measuring Awareness in People With Dementia: Results of a Systematic Scoping Review

BACKGROUND

Awareness of the diagnosis or related changes in functioning varies in people with dementia (PwD), with implications for the well-being of PwD and their carers. Measuring awareness in a clinical setting could facilitate tailored support and optimize involvement in personal health and care decisions. This scoping review aimed to identify validated methods of assessing awareness in dementia and appraise their clinical utility.

METHOD

A systematic search was conducted of English-language publications that measured awareness in PwD, in 6 electronic databases. Search terms included dement*, Alzheimer*, Pick disease, and awareness, unawareness, anosognosia, insight, denial, metacognit*, or discrepanc*.

RESULTS

We screened 30,634 articles, finding 345 articles that met our inclusion criteria. We identified 76 measures, most commonly using a discrepancy questionnaire comparing evaluations of function by PwD and an informant. There were 30 awareness measures developed and validated for use in dementia populations but few designed for general clinical use.

CONCLUSIONS

Although we found a range of clinical indications for measuring awareness, there were few studies investigating clinical applications and few tools designed for clinical purposes. Further investigation and development of a person-centered tool could facilitate health and care choices in mild-to-moderate dementia.

Genetic underpinnings of sociability in the general population

Levels of sociability are continuously distributed in the general population, and decreased sociability represents an early manifestation of several brain disorders. Here, we investigated the genetic underpinnings of sociability in the population. We performed a genome-wide association study (GWAS) of a sociability score based on four social functioning-related self-report questions from 342,461 adults in the UK Biobank. Subsequently we performed gene-wide and functional follow-up analyses. Robustness analyses were performed in the form of GWAS split-half validation analyses, as well as analyses excluding neuropsychiatric cases. Using genetic correlation analyses as well as polygenic risk score analyses we investigated genetic links of our sociability score to brain disorders and social behavior outcomes. Individuals with autism spectrum disorders, bipolar disorder, depression, and schizophrenia had a lower sociability score. The score was significantly heritable (SNP h2 of 6%). We identified 18 independent loci and 56 gene-wide significant genes, including genes like ARNTL, DRD2, and ELAVL2. Many associated variants are thought to have deleterious effects on gene products and our results were robust. The sociability score showed negative genetic correlations with autism spectrum, disorders, depression, schizophrenia, and two sociability-related traits-loneliness and social anxiety-but not with bipolar disorder or Alzheimer's disease. Polygenic risk scores of our sociability GWAS were associated with social behavior outcomes within individuals with bipolar disorder and with major depressive disorder. Variation in population sociability scores has a genetic component, which is relevant to several psychiatric disorders. Our findings provide clues towards biological pathways underlying sociability.

Resting functional connectivity in the semantic appraisal network predicts accuracy of emotion identification

OBJECTIVE

Structural and task-based functional studies associate emotion reading with frontotemporal brain networks, though it remains unclear whether functional connectivity (FC) alone predicts emotion reading ability. The predominantly frontotemporal salience and semantic appraisal (SAN) networks are selectively impacted in neurodegenerative disease syndromes like behavioral-variant frontotemporal dementia (bvFTD) and semantic-variant primary progressive aphasia (svPPA). Accurate emotion identification diminishes in some of these patients, but studies investigating the source of this symptom in patients have predominantly examined structural rather than functional brain changes. Thus, we investigated the impact of altered connectivity on their emotion reading.

METHODS

One-hundred-eighty-five participants (26 bvFTD, 21 svPPA, 24 non-fluent variant PPA, 24 progressive supranuclear palsy, 49 Alzheimer's disease, 41 neurologically healthy older controls) underwent task-free fMRI, and completed the Emotion Evaluation subtest of The Awareness of Social Inference Test (TASIT-EET), watching videos and selecting labels for actors' emotions.

RESULTS

As expected, patients averaged significantly worse on emotion reading, but with wide inter-individual variability. Across all groups, lower mean FC in the SAN, but not other ICNs, predicted worse TASIT-EET performance. Node-pair analysis revealed that emotion identification was predicted by FC between 1) right anterior temporal lobe (RaTL) and right anterior orbitofrontal (OFC), 2) RaTL and right posterior OFC, and 3) left basolateral amygdala and left posterior OFC.

CONCLUSION

Emotion reading test performance predicts FC in specific SAN regions mediating socioemotional semantics, personalized evaluations, and salience-driven attention, highlighting the value of emotion testing in clinical and research settings to index neural circuit dysfunction in patients with neurodegeneration and other neurologic disorders.

Domains of awareness in Alzheimer's disease: The influence of executive function

OBJECTIVE

Awareness is a developing area in dementia research and the evaluation of its domains has been increasingly included as part of care for people with Alzheimer's disease (PwAD). Our aim is to examine whether executive dysfunction is associated with awareness domains.

METHODS

A consecutive series of 75 people with mild-to-moderate Alzheimer's disease completed assessments about global cognitive function, executive functioning, and their awareness of disease. Their primary caregivers' dyad provided information about demographics, awareness of disease, dementia severity, neuropsychiatric symptoms, and functional status.

RESULTS

Different types of executive dysfunction were presented as a predictor for awareness of disease (cognitive flexibility, inhibitory control, and working memory), of emotional state (short-term memory and attention) and of social functioning and relationships (visuospatial organization, integrative functions, and abstract thinking). Awareness of cognitive functioning and health condition and of functional activity impairments exhibit only global cognitive function as a predictor.

CONCLUSIONS

Findings confirm some degree of independence between awareness domains. The importance of identifying differences in domains of awareness relies in the understanding of awareness as a clinical phenomenon in order to guide the management and support of PwAD and their caregivers.

Domains of Awareness in Young and Late Onset Dementia

BACKGROUND

There is a lack of research investigating whether there are differences in the domains of awareness according to the age at onset of dementia.

OBJECTIVE

This study is designed to investigate differences in awareness of cognitive functioning and health condition, functional activity impairments, emotional state, and social functioning and relationships among people with young onset (YOD) and late onset dementia (LOD); and examine associations between awareness and its domains with cognition, functionality, neuropsychiatric symptoms, social and emotional functioning, and quality of life (QoL) in both groups.

METHODS

A group of 136 people with dementia and their respective caregivers (YOD = 50 and LOD = 86) were consecutively selected. We assessed awareness of disease, dementia severity, cognition, functionality, neuropsychiatric symptoms, social and emotional functioning, and QoL.

RESULTS

People with YOD had more neuropsychiatric symptoms than people with LOD. People with YOD were more aware of disease (total score), of their cognitive functioning and health condition and of their functional activity impairments, even if this group was more severely cognitive impaired and had a worse level of functionality than LOD group. Multivariate linear regressions showed that functionality has a wide relationship to awareness for people with YOD. While neuropsychiatric symptoms and QoL has a greater relation to awareness for people with LOD.

CONCLUSION

Different clinical variables are associated to different domains in YOD and LOD groups, reinforcing the heterogeneity of awareness in 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.

Measuring the well-being of people with dementia: a conceptual scoping review

BACKGROUND

Enabling people with dementia to 'live well' is a policy and research priority in many countries. However, instruments for measuring outcomes of psychosocial interventions designed to promote well-being in dementia are often derived from a symptom-focused, loss/deficit approach, or from broad quality of life concepts. A pan-European dementia working group called for research on the development of an alternative asset/strengths-based conceptual framework of well-being in dementia. This paper takes forward this recommendation by developing such a framework and using this to map relevant self-report outcome measures.

METHODS

Three scoping reviews of published studies were conducted iteratively. First, we examined the literature on lived experiences of well-being and quality of life in people with dementia and then the wider dementia literature for application of well-being constructs. The synthesised findings generated conceptual domains of well-being in people with dementia. Corresponding self-report instruments used in dementia research were scoped, categorised within the conceptual framework and their potential value in measuring outcomes for people with dementia was examined.

FINDINGS

Six conceptual domains for the measurement of well-being and 35 self-report instruments that have been used with people with dementia were identified. Six instruments were developed specifically for people with dementia, five were derived from the gerontological literature and 24 from the well-being literature. Fifteen instruments and one sub-scale have been examined for psychometric properties amongst people with dementia. To date, 20 have been used as outcome measures, with seven measuring change over time. A number of identified instruments utilise traditional retrospective Likert-scaling response formats, limiting their potential for use with some groups of people with dementia.

CONCLUSION

An assets/strengths-based framework is presented, outlining structural domains for selecting self-report measures of well-being in people with dementia. It provides a foundation for enhancing research into processes and outcomes of psychosocial interventions, including instrument development, more precise matching of intervention aims with outcome measurement, and newer technology-based 'in-the-moment' measurement.

Patterns of discrepancies in different objects of awareness in mild and moderate Alzheimer's disease

Objectives: Awareness is considered a heterogeneous and non-linear phenomenon in dementia. We aim to investigate patterns of change of different domains of awareness (awareness of cognitive functioning and health condition, activities of daily living, emotional state, social functioning, and relationships) in people with mild and moderate Alzheimer's disease (AD) and aspects related to each domain.Method: Cross-sectional assessment of dyads of people with AD (PwAD) and caregivers (n = 128; CDR1 = 74, CDR2 = 54). PwAD completed assessments about quality of life, cognition and their awareness of disease. Caregivers provided information about PwAD and received quality of life and burden of care assessments.Results: Mild AD group showed a mildly impaired awareness (n = 40; 54.05%), while moderate AD group, showed higher presence of moderately impaired awareness (n = 22; 40.74%). There was a significant difference between groups in awareness of cognitive functioning and health condition (p < 0.004), functional activity impairments (p < 0.001) and total score of awareness (p < 0.01). Conversely, awareness of emotional state (p = 0.22) and of social functioning and relationship (p = 0.44) presented no significant difference between groups. Unawareness of functional activity impairments showed higher discrepancy scores between PwAD and caregivers in both groups.Conclusions: Significant differences were found only in patterns of discrepancies in awareness of cognitive functioning and health condition, of ADL and socio-emotional functioning. Different factors are related to different domains in mild and moderate group, reinforcing the heterogeneity of awareness in dementia. ADL deficits have an important role in awareness phenomenon, independent of the severity of disease.

Measuring awareness in people with dementia: protocol for a scoping review

BACKGROUND

People with dementia (PwD) vary in the degree of awareness they show about their situation, both generally concerning the diagnosis and more specifically around certain aspects or objects of awareness such as awareness of memory impairment, altered daily activities or social functioning. The extent of awareness or lack of awareness has consequences for well-being of PwD and carers, impacting on rates of hospital admission, institutionalization, mood, adjustment to diagnosis, outcomes from intervention and carer burden. An accurate estimation of a person's awareness could therefore be useful in a clinical setting to support PwD and their carers in making appropriate choices for health and care decisions, and could facilitate safe management by health care professionals, e.g. in an acute care setting. There is a range of different approaches to measuring awareness reported in the dementia research literature, with varying estimates of the frequency of lack of awareness, reflecting different methodologies and populations. The majority of the methods have been developed for research purposes and may not be suitable for clinical use. There are no recent scoping or systematic reviews of the available methods.

METHOD

We will conduct a scoping review of published studies that have assessed awareness in people with dementia of all types, and all degrees of severity. The systematic search will include the electronic databases PubMed, Embase, PsycInfo, CINAHL, Web of Science and Cochrane Library, using search terms for dementia ("dement*" or "Alzheimer*" or "Pick's disease") and "awareness", "unawareness", "anosognosia", "insight", "denial", "metacognit*" or "discrepanc*" identified from pilot searches. Findings will be mapped and described according to the method used, the setting and diagnosis and the object of awareness studied if specified. Validated measures will be identified.

DISCUSSION

This scoping review will provide an overview of the methods used to measure awareness in people with dementia, allowing comparison of the methods along with identification of validated measures. The methods or components will be appraised for potential clinical use, and gaps in research will be highlighted.

Awareness in Dementia: Development and Evaluation of a Short Version of the Assessment Scale of Psychosocial Impact of the Diagnosis of Dementia (ASPIDD-s) in Brazil

Awareness of disease is defined as the recognition of changes caused by the deficits related to the disease process. We aimed to examine the psychometric properties of the short versions of the Assessment Scale of Psychosocial Impact of the Diagnosis of Dementia (ASPIDD-s), a multidimensional awareness scale. Using a cross-sectional design, we included 201 people with dementia and their family caregivers. The creation of the short versions was based on items with higher loadings on each factor, the correlations between the short versions and demographic or clinical variables and the relevance of the item to the respondent population. Three short versions were created: version 1 and 3, with 12 items and version 2, with 16 items. The short versions correlated very strongly with the full scale and with the 4 factors of the original scale, maintaining the multidimensional nature of the ASPIDD. Loss of awareness was associated with worse quality of life, decreased functionality and cognitive level, and higher caregiver burden across the short versions. Considering the appropriateness of the items and their clinical relevance, we recommend version 3 for use. With only 12 items, the time required for the completion of the scale is short, while maintaining robust psychometric properties.

The social functioning in dementia scale (SF-DEM): Exploratory factor analysis and psychometric properties in mild, moderate, and severe dementia

Introduction

The psychometric properties of the social functioning in dementia scale over different dementia severities are unknown.

Methods

We interviewed 299 family carers of people with mild, moderate, or severe dementia from two UK research sites; examined acceptability (completion rates); conducted exploratory factor analysis; and tested each factor's internal consistency and construct validity.

Results

Of 299, 285 (95.3%) carers completed questionnaires. Factor analysis indicated three distinct factors with acceptable internal consistency: spending time with other people, correlating with overall social function (r = 0.56, P < .001) and activities of daily living (r = −0.48, P < .001); communicating with other people correlating with activities of daily living (r = −0.66, P < .001); and sensitivity to other people correlating with quality of life (r = 0.35, P < .001) and inversely with neuropsychiatric symptoms (r = −0.45, P < .001). The three factors' correlations with other domains were similar across all dementia severities.

Discussion

The social functioning in dementia scale carer version measures three social functioning domains and has satisfactory psychometric properties in all severities of dementia.

Incongruent perceptions of the care values of hospitalized persons with dementia: a pilot study of patient-family caregiver dyads

OBJECTIVE

Many difficult decisions are made in the inpatient hospital setting regarding the daily care of persons with dementia (PWDs). Incongruent perceptions of the PWD's care values limit the family caregiver's ability to make surrogate decisions. The objectives of this pilot study were to describe and identify determinants of incongruent perceptions in the hospital setting.

METHODS

Using multilevel modeling (MLM), we examined cross-sectional data collected from 42 PWD-family caregiver dyads.

RESULTS

There was a significant amount of incongruence, on average, for all four subscales representing the PWD's care values: autonomy = -0.33 (p < .001); burden = -.49 (p < .001); safety/quality of care = -.26 (p < .001); and social interactions = -.21 (p = .004). Family caregivers (CG) rated the importance of care values to the PWD as lower than the PWD rated the importance. Determinants of greater incongruence included higher relationship strain and fewer positive dyadic interactions.

CONCLUSION

Our findings reveal significant levels of incongruence in perceptions of the PWD's values among dementia care dyads in the hospital setting. Our analysis suggests a potential impact of relationship variables on incongruence. Further research is needed around this overlooked interpersonal context for supporting the dementia care dyad in the hospital setting.

The Relationship Between Social Cognition and Awareness in Alzheimer Disease

A large body of evidence highlights the social cognitive impairment in neurodegenerative diseases such Alzheimer disease (AD). This study investigated the relationship among social and emotional functioning (SEF), awareness of disease, and other clinical aspects in people with AD (PwAD). A consecutive series of 50 people with mild to moderate AD and their 50 family caregivers were assessed. There was a significant difference between self-rated SEF and informant-rated SEF. In 56% of PwAD, self-rated SEF is lower than informant-rated SEF. People with AD mostly presented with mildly impaired awareness of the disease (56%), 20% had moderately impaired awareness of the disease, and 6% were unaware of the disease. The multivariate linear regression showed that informant-rated SEF was related to the social functioning, and relationships, domains of awareness of disease, and the PwAD informant-rated quality of life. The relationship between SEF and awareness of social functioning and relationship domain shows that they are comprised of judgments related to perceptions about oneself, values, and beliefs qualitatively different from awareness of memory or functionality, which can be directly observed.

Development of an instrument to assess social functioning in dementia: The Social Functioning in Dementia scale (SF-DEM)

Introduction

Social functioning is a core domain in the life of people with dementia, but there is no accepted instrument to measure it. We aimed to develop the Social Functioning in Dementia (SF-DEM) scale and test its psychometric properties for assessing social function in people with dementia.

Methods

We interviewed people with mild dementia and family caregivers to develop patient and caregiver-rated SF-DEM versions and refined them through interviews with health care professionals. We tested its psychometric properties in 30 dyads of people with dementia and family caregivers.

Results

Both SF-DEM versions had content validity and demonstrated concurrent validity against a single item rating overall social functioning (patient rated r = 0.42, 95% CI [0.07–0.68]; caregiver rated r = 0.59, 95% CI [0.29–0.78]). All participants found it acceptable. Analyses showed reliability (test–retest, inter-rater, internal consistency) and indications of responsiveness to change.

Discussion

SF-DEM shows promise as a valid, reliable, acceptable measure of social functioning in dementia.

•

Social function is key to dementia diagnosis and important to patients and families.

•

SF-DEM is the first assessment tool for measuring social functioning in dementia.

•

In SF-DEM, core social functioning domains are assessed by self- or proxy-report.

•

These measures are acceptable to clinicians and respondents, and are reliable.

•

SF-DEM has content and concurrent validity in mild dementia.

Spouses' experience of living with a partner diagnosed with a dementia: a synthesis of the qualitative research

BACKGROUND

The majority of people diagnosed with a dementia live at home with the support of their spouse. While this situation has advantages, it brings many challenges for the spouse, particularly dealing with the emotional impact of the behavioral changes associated with the dementia. A growing body of qualitative research has focused on understanding the spousal caregiver perspective of living with a partner diagnosed with dementia. The aim of this study was to complete a synthesis of the results of published qualitative studies that have explored the spousal experience.

METHOD

An electronic database search of Ovid Medline, CINAHL, EMBASE, and PsychINFO from January 1980 to September 2014 was conducted. Sixteen studies met the inclusion criteria. Verbatim quotes of the participant interview data derived from these studies were collated and a thematic analysis was conducted.

RESULTS

Synthesis of the published data revealed five major themes. The theme of "loss of partner" was central, and around this central experience spouses described various processes: acknowledging change, being in crisis, adapting and adjusting, accepting and moving forward.

CONCLUSIONS

These findings provide insights into the day-to-day adjustments and experiences of spousal caregivers whilst highlighting the importance of considering the impact of cognitive decline and dementia in a social-relational context.

Concepts and objects of awareness in Alzheimer’s disease: an updated systematic review

ABSTRACT Objectives To compare and discuss the objects of awareness in Alzheimer’s disease (AD): awareness of cognitive deficits, of functional activities, of social-emotional functioning and behavioral impairment. Methods A search in the PsycINFo, Pilots, PubMed/Medline and ISI electronic databases according to Prisma methodology was performed. We included studies about awareness in people with AD published between 2010 and 2015, with the combination of keywords: “Alzheimer AND awareness of deficits”, “Alzheimer AND anosognosia”, “Alzheimer AND insight”, “dementia AND awareness of deficits”, “dementia AND anosognosia”, “dementia AND insight”. The articles were categorized according to the specific object of awareness. Results Seven hundred and ten records were identified and, after application of the exclusion criteria, 191 studies were retrieved for potential use. After excluding the duplicates, 46 studies were included. Most studies assessed the cognitive domain of awareness, followed by the functional, social-emotional, and behavioral impairment domains. Memory deficits were not sufficient to explain impaired awareness in AD. Longitudinal studies did not find discrepancies between patients and caregivers’ reports, indicating that awareness is not related to cognition. Conflicting findings were observed, including the relation between awareness, mood, severity of disease, and personal characteristics. Conclusions The studies show lack of conceptual consensus and significant methodological differences. The inclusion of samples without differentiation of dementia etiology is associated to symptomatic differences, which affect awareness domains. Awareness in AD is a complex and multidimensional construct. Different objects elicit different levels of awareness.

Cross-cultural adaptation of the Social and Emotional Questionnaire on Dementia for the Brazilian population

CONTEXT AND OBJECTIVE

Impairments in social and emotional functioning may affect the communication skills and interpersonal relationships of people with dementia and their caregivers. This study had the aim of presenting the steps involved in the cross-cultural adaptation of the Social and Emotional Questionnaire (SEQ) for the Brazilian population.

DESIGN AND SETTING

Cross-cultural adaptation study, conducted at the Center for Alzheimer's Disease and Related Disorders in a public university.

METHODS

The process adopted in this study required six consecutive steps: initial translation, translation synthesis, back translation, committee of judges, pretesting of final version and submission to the original author.

RESULTS

In general, the items had semantic, idiomatic, conceptual and experiential equivalence. During the first pretest, people with dementia and their caregivers had difficulties in understanding some items relating to social skills, which were interpreted ambiguously. New changes were made to allow better adjustment to the target population and, following this, a new pretest was performed. This pre-test showed that the changes were relevant and gave rise to the final version of the instrument. There was no correlation between education level and performance in the questionnaire, among people with dementia (P = 0.951).

CONCLUSION

The Brazilian Portuguese version of the Social and Emotional Questionnaire was well understood and, despite the cultural and linguistic differences, the constructs of the original version were maintained.

Carer assessment: continuing tensions and dilemmas for social care practice

Since the early 1990s, UK social care policy has committed to supporting carers. Legislation (England and Wales) over this time period has recognised the importance of separate carer assessments that take into account an individual's ability and willingness to care. This paper considers carer assessment from the perspective of social care practitioners. It reports on qualitative data from a carer research programme that spans over 20 years (1993 to present) and includes 383 in-depth interviews with social care practitioners across England and Wales. Offering unique longitudinal insights, we identify some persistent tensions associated with the translation of UK carer assessment policy into social care practice. We explore practitioners' long-standing ambivalence towards carer assessment and their reluctance to evidence carer need via a separate assessment process. Deficits relating to the conduct of carer assessment are identified. For example, the reliance on structured, problem-focused assessment protocols that restrict discussions to the personal care aspects of caring and fail to capture the complex, diverse lives that carers lead. Carer assessments do not reflect the reciprocal nature of many caring relationships, as a one-way direction of care is assumed. They do not take into account the broader support network of individuals who may be involved in helping someone with complex care needs. Carer willingness to care continues to be taken for granted and planning for the future is a significant gap in carer assessment practice. The proposed changes to the social care systems across England and Wales provide a timely opportunity to review the process and conduct of carer assessment. Policy guidance needs to clarify the links between service user and carer assessments and the way these align within broader assessment and care management frameworks. Assessment tools that encourage a narrative approach to carer assessment and capture the affective aspects of care-giving could benefit future practice.

Predictors of perceived functional ability in early-stage dementia: self-ratings, informant ratings and discrepancy scores

OBJECTIVE

Assessing functional ability is an important element in diagnosing and monitoring the progression of dementia, with research suggesting a link between functional ability and cognition. We investigated the predictors of total score and individual item functional ratings made by people with dementia (PwD), carers of PwD and the resulting discrepancy score.

METHODS

People with early-stage Alzheimer's disease, vascular or mixed dementia (n = 100) and their carers completed the Functional Activities Questionnaire. PwD also completed tests of memory, verbal executive function, language and cognitive screening, and provided ratings of mood. Carers provided a rating of stress.

RESULTS

Immediate memory predicted self-rated functioning, whereas carer stress predicted informant-rated functioning. Letter fluency predicted the discrepancy between self-rated and informant-rated functioning. For self-rated functioning, the direction and pattern of the individual item predictors suggested a degree of functional awareness. Informant ratings were dominated by carer stress and, to a lesser extent, everyday memory. The discrepancy scores were also predicted by carer stress and everyday memory, but also letter fluency.

CONCLUSIONS

Self-rated functioning showed evidence of awareness based on the direction and pattern of significant individual item predictors. Informant ratings, however, were found to be significantly influenced by carer stress. The findings have implications for the use of perceived functional ratings in clinical and research settings.

What contributes to a good quality of life in early dementia? Awareness and the QoL-AD: a cross-sectional study

Background

Self-report quality of life (QoL) measures for people with dementia are widely used as outcome measures in trials of dementia care interventions. Depressed mood, relationship quality and neuropsychiatric symptoms predict scores on these measures, whereas cognitive impairment and functional abilities typically do not. This study examines whether these self-reports are influenced by personality and by the person’s awareness of his/her impairments. A strong negative association between QoL and awareness of deficits would have implications for the validity of self-report in this context and for therapeutic interventions aiming to increase adjustment and coping.

Methods

Participants were 101 individuals with early‒stage dementia and their family carers participating in the Memory Impairment and Dementia Awareness (MIDAS) Study. QoL was assessed using the QoL-AD scale, and awareness was assessed in relation to memory, activities of daily living and social functioning. Self-concept, conscientiousness, quality of relationship and mood were assessed and a brief neuropsychological battery administered. Carers rated their own stress and well-being and reported on neuropsychiatric symptoms. A series of regression analyses predicting QoL-AD were carried out, identifying key variables in each domain of assessment to take forward to an overall model.

Results

Cognitive impairment was not related to QoL. The final model accounted for 57% of the variance in QoL-AD scores, with significant contributions from depressed mood, severity of irritability shown by the person with dementia, self-concept, quality of relationship (rated by the person with dementia) and male gender. The bivariate relationships of QoL-AD with awareness of memory function, awareness of functional abilities and conscientiousness were mediated by both depressed mood and self-concept.

Conclusions

This study reports the most comprehensive approach to evaluation of awareness to date. Most of the indices of awareness used are not related to self-reported QoL. Discrepancies in evaluative judgements of memory function and functional abilities between people with dementia and carers are related to QoL, but this relationship is mediated by both depressed mood and self-concept, which have a much stronger relationship with QoL. The validity of self-report measures of QoL in people with early stage dementia is supported by these results.

Consciência do déficit na doença de Alzheimer: diferenças entre os domínios cognitivo e funcional

OBJETIVOS: Revisar sistematicamente desenhos de estudo, instrumentos de avaliação e fatores relacionados ao comprometimento dos domínios cognitivo e funcional da consciência do déficit em pessoas com doença de Alzheimer (DA). MÉTODO: Pesquisa nas bases de dados PubMed e ISI de estudos sobre consciência do déficit na DA publicados entre 2008 e 2013. As palavras-chave utilizadas foram: "dementia", "Alzheimer", "awareness", "awareness of memory" e "awareness of functioning", "deficits", "cognition". RESULTADOS: Os 10 artigos selecionados utilizaram os conceitos "falta de consciência do déficit", "anosognosia", "insight", "falta de consciência das dificuldades cognitivas" e "consciência limitada das deficiências". A etiologia do comprometimento da consciência do déficit foi relacionada a fatores biológicos como gravidade clínica da doença, associações neuroanatômicas, alterações neuropsiquiátricas e fatores psicológicos e sociais. O desenho de estudo mais utilizado foi o corte transversal. No domínio cognitivo, a memória e as funções executivas foram as duas principais funções investigadas. No domínio funcional, foram encontradas associações com a disfunção executiva, declínio da interação social, depressão e a influência do desempenho ocupacional. CONCLUSÕES: As distintas hipóteses etiológicas, a operacionalização variável do conceito e a falta de instrumentos de avaliação padronizados impossibilitam a obtenção de resultados homogêneos. Essas dificuldades comprometem a compreensão e a investigação dos domínios cognitivo e funcional.

Emotion recognition in mild cognitive impairment: relationship to psychosocial disability and caregiver burden

BACKGROUND

Impaired emotion recognition in dementia is associated with increased patient agitation, behavior management difficulties, and caregiver burden. Emerging evidence supports the presence of very early emotion recognition difficulties in mild cognitive impairment (MCI); however, the relationship between these impairments and psychosocial measures is not yet explored.

METHODS

Emotion recognition abilities of 27 patients with nonamnestic MCI (naMCI), 29 patients with amnestic MCI (aMCI), and 22 control participants were assessed. Self-report measures assessed patient functional disability, while informants rated the degree of burden they experienced.

RESULTS

Difficulties in recognizing anger was evident in the amnestic subtype. Although both the patient groups reported greater social functioning disability, compared with the controls, a relationship between social dysfunction and anger recognition was evident only for patients with naMCI. A significant association was found between burden and anger recognition in patients with aMCI.

CONCLUSIONS

Impaired emotion recognition abilities impact MCI subtypes differentially. Interventions targeted at patients with MCI, and caregivers are warranted.

Awareness of executive deficits in people with Parkinson's disease

Executive functioning is frequently impaired among people with Parkinson's disease (PD). Little is known about awareness of executive functioning, in the sense of being able to accurately appraise functioning or performance, in people with PD, or about whether awareness is particularly affected in those who have impaired executive functioning. This study explored awareness of executive functioning at the levels of evaluative judgment (comparison of self- and informant ratings of executive functioning), and performance monitoring (comparison of performance on cognitive tests and self-ratings of that performance). Awareness levels were assessed in people with PD with and without executive deficits, and in healthy controls. When the level of agreement between self- and informant ratings was considered, people with PD in both groups appeared as accurate in evaluating their overall executive functioning as healthy controls. When appraising their performance as the specific tasks were completed, people with PD who had impairments in executive functioning appeared less accurate than controls and people with PD without executive impairments. People with PD who have executive deficits may lack the ability to recognize their limitations while performing specific tasks, which may have implications for their functional abilities.
