Course and Determinants of Anosognosia in Alzheimer’s Disease: A 12-Month Follow-up

Jargonaphasia in logopenic variant primary progressive aphasia

BACKGROUND

Logopenic variant primary progressive aphasia (lvPPA), which is most commonly an early onset variant of Alzheimer's disease (AD), is a progressive impairment in word retrieval and language expression. Clinicians often misdiagnose these patients when they present with severely unintelligible speech consistent with jargonaphasia.

METHODS

We reviewed all patients presenting to a behavioral neurology program over a 23-year period who met criteria for lvPPA after completion of an evaluation extending to positron emission tomography (PET) of the brain. Among these lvPPA patients, we additionally identified and characterized those whose presentation involved incomprehensible yet fluent verbal output.

RESULTS

Out of 95 patients with lvPPA, 9 (9.47%) had jargonaphasia on presentation. These patients differed from the remaining 86 patients in lacking awareness or concern for their impaired communication, having worse mental status scale scores, greater auditory comprehension difficulty, and more bilateral temporo-parietal hypometabolism. In addition, 44.4% of those with jargonaphasia, compared to 14% of those without, were bi/multilingual.

CONCLUSION

Nearly 1 in 10 patients with lvPPA present with severely unintelligible speech. These patients have disease extending to bilateral temporoparietal areas affecting language comprehension and disease awareness. Jargonaphasia can be a confusing presentation of AD and must be differentiated from other progressive aphasias, Wernicke's aphasia, and the word salad of "schizoaphasia".

Metacognitive Improvements Following Cognitive Stimulation Therapy for People with Dementia: Evidence from a Pilot Randomized Controlled Trial

OBJECTIVES

Impaired self-awareness is a common feature of dementia, with considerable clinical impact. Some therapeutic strategies such as cognitive stimulation and psychotherapy have been suggested to mitigate loss of awareness. Nevertheless, evidence of intervention improving awareness of deficits is scarce. The present study aims to explore the impact of a Brazilian adapted version of Cognitive Stimulation Therapy (CST-Brasil), an evidence-based psychosocial intervention for people with dementia (PwD), on the level of awareness, reporting here a secondary outcome of a pilot randomized controlled trial.

METHODS

47 people with mild to moderate dementia attending an out-patient unit were randomly allocated to CST (n = 23) or treatment as usual (TAU) (n = 24) across 7 weeks, in a pilot randomized controlled trial. Awareness was measured before and after the intervention.

RESULTS

Results indicated that people in both groups increased in overall awareness of the disease, but only those receiving CST exhibited improvements of awareness of cognitive ability.

CONCLUSIONS

These findings suggest that CST may also improve metacognitive abilities in PwD, which could potentially be applied to other settings with beneficial effects.

CLINICAL IMPLICATIONS

Considering the negative impacts of anosognosia, CST-led improvements in awareness have the potential to benefit PwD and their caregivers.

Identification of Major Cognitive Disorders in Self-Reported versus Administrative Health Data: A Cohort Study in Quebec

BACKGROUND

The first imperative in producing the relevant and needed knowledge about major neurocognitive disorder (MNCD) is to identify people presenting with the condition adequately. To document potential disparities between administrative health databases and population-based surveys could help identify specific challenges in this population and methodological shortfalls.

OBJECTIVE

To describe and compare the characteristics of community-dwelling older adults according to four groups: 1) No MNCD; 2) Self-reported MNCD only; 3) MNCD in administrative health data only; 4) MNCD in both self-reported and administrative health data.

METHODS

This retrospective cohort study used the Care Trajectories-Enriched Data (TorSaDE) cohort, a linkage between five waves of the Canadian Community Health Survey (CCHS) and health administrative health data. We included older adults living in the community who participated in at least one cycle of the CCHS. We reported on positive and negative MNCD in self-reported versus administrative health data. We then compared groups' characteristics using chi-square tests and ANOVA.

RESULTS

The study cohort was composed of 25,125 older adults, of which 784 (3.12%) had MNCD. About 70% of people with an MNCD identified in administrative health data did not report it in the CCHS. The four groups present specific challenges related to the importance of perception, timely diagnosis, and the caregivers' roles in reporting health information.

CONCLUSION

To a certain degree, both data sources fail to consider subgroups experiencing issues related to MNCD; studies like ours provide insight to understand their characteristics and needs better.

Anosognosia in Dementia: Evaluation of Perfusion Correlates Using 99mTc-HMPAO SPECT and Automated Brodmann Areas Analysis

(1) Background: Considerable inconsistency exists regarding the neural substrates of anosognosia in dementia in previous neuroimaging studies. The purpose of this study was the evaluation of anosognosia perfusion correlates across various types of dementia using automated Brodmann areas (BAs) analysis and comparison with a database of normal subjects. (2) Methods: We studied 72 patients: 32 with Alzheimer’s disease, 26 with frontotemporal dementia—FTD (12 behavioral FTD, 9 semantic FTD, 5 Progressive Non-Fluent Aphasia), 11 with corticobasal syndrome, and 3 with progressive supranuclear palsy. Addenbrook’s Cognitive Examination—Revised (ACE-R) mean(±SD) was 55.6(±22.8). For anosognosia measurement, the Anosognosia Questionnaire—Dementia was used. Total anosognosia score mean(±SD) was 22.1(±17.9), cognitive anosognosia score mean(±SD) was 18.1(±15.1) and behavioral–mood anosognosia score mean(±SD) was 3.3(±4.7). (3) Results: Higher anosognosia total score was associated with hypoperfusion in the inferior temporal, anterior cingulate, and inferior frontal cortices of the right hemisphere (BAs 20R, 24R, 32R, 45R). Higher anosognosia cognitive score was correlated with hypoperfusion in the left middle and anterior temporal cortices, and right dorsal anterior cingulate cortex (BAs 21L, 22L, 32R). No association was found with behavioral–mood anosognosia. (4) Conclusions: Automated analysis of brain perfusion Single Photon Emission Computed Tomography could be useful for the investigation of anosognosia neural correlates in dementia.

Changes in awareness of condition in people with mild-to-moderate dementia: Longitudinal findings from the IDEAL cohort

OBJECTIVES

Awareness of difficulties shown by people with dementia is known to vary, but few studies have explored changes in awareness over time. Investigating this could further the understanding of surrounding concepts and reasons for impaired awareness. Recognising emerging or diminishing awareness could facilitate discussions about diagnosis and appropriate post-diagnostic support.

METHODS

Using longitudinal data from the Improving the experience of Dementia and Enhancing Active Life (IDEAL) cohort, awareness in community-dwelling people with mild-to-moderate dementia was assessed at three timepoints over 2 years. A validated checklist was used to evaluate awareness of difficulties associated with dementia. We examined changes in awareness for people with low awareness at baseline, and used case-matching to describe differences in characteristics between people who gained awareness, and those who continued with low awareness.

RESULTS

At baseline, 83 people from a sample of 917 showed low awareness. The majority of those remaining in the study at later timepoints had gained awareness, some as late as four or more years after diagnosis. Case-matched comparisons revealed few distinguishing characteristics: cases with stable low awareness had similar or better cognitive and functional ability than those who gained and retained awareness at 12 and 24 months, but may have had more co-morbidities.

CONCLUSIONS

Self-reported awareness of difficulties can change and may increase over time in people with mild-to-moderate dementia. There may be individual reasons for ongoing low awareness, not explained by cognitive or functional ability. This challenges the view that a single record of low awareness represents a fixed disease-related symptom, and highlights the complex, individual and dynamic nature of awareness.

Awareness for People With Alzheimer’s Disease: Profiles and Weekly Trajectories

Objective: To understand awareness and fluctuations of awareness in Alzheimer’s disease (AD), it is fruitful to consider the objects of awareness, e.g., cognitive functioning or recognition of the disease, as well as the mechanisms and modes of expression underlying awareness. With a holistic and discourse-centered approach, we aimed to identify different awareness profiles and test whether these profiles were stable or whether transitions from one profile to another occurred over short time intervals.

Methods: Twenty-eight residents of nursing homes with a diagnosis of AD participated in four semistructured interviews at biweekly intervals. These interviews were cluster analyzed to determine profiles of awareness. A Markov chain was applied to model their fluctuation.

Results: Five awareness profiles were observed that differed in terms of objects and underlying processes. Awareness proved to be quite stable for four of the five profiles. Interindividual variability in awareness was also observed through numerous different trajectories that were identified.

Discussion: Self-awareness and disease awareness are characterized by profiles that vary subtly between individuals. Fluctuations in awareness underscore the need to employ assessment intervals that closely reflect daily life in institutions.

Does awareness of condition help people with mild-to-moderate dementia to live well? Findings from the IDEAL programme

Background

People living with dementia vary in awareness of their abilities. We explored awareness of the condition and diagnosis in people with mild-to-moderate dementia, and how this relates to quality of life, well-being, life satisfaction, and caregiver stress.

Methods

This study was a cross-sectional exploratory analysis of data from the IDEAL cohort, which recruited people with dementia living at home and available caregivers from 29 research sites in Great Britain. Our study included 917 people with mild-to-moderate dementia and 755 carers. Low and high awareness groups were derived from self-reported responses to a dementia representation measure. Logistic regression was used to explore predictors of awareness of condition and diagnosis using demographic, cognitive, functional and psychological measures, and the relationship with quality of life, well-being and life satisfaction (‘living well’), and caregiver stress.

Results

There were 83 people with low awareness of their condition. The remaining 834 people showed some awareness and 103 of these had high awareness of their condition and diagnosis. Psychosocial factors were stronger predictors of awareness than cognitive and functional ability. Those with higher awareness reported lower mood, and lower scores on indices of living well as well as lower optimism, self-efficacy and self-esteem. Low awareness was more likely in those aged 80y and above, and living in more socially deprived areas. No relationship was seen between caregiver stress and awareness.

Conclusions

Awareness of the condition and diagnosis varies in people with mild-to-moderate dementia and is relevant to the capability to live well. Awareness should be considered in person-centered clinical care.

Functional connectivity differences in Alzheimer's disease and amnestic mild cognitive impairment associated with AT(N) classification and anosognosia

Alzheimer's continuum biological profiles (A⁺T^-N^-, A⁺T⁺N^-, A⁺T^-N⁺, and A⁺T⁺N⁺) were established in the 2018 National Institute on Aging and Alzheimer's Association research framework for Alzheimer's disease (AD). We aim to assess the relation between AT(N) biomarker profiles and brain functional connectivity (FC) and assess the neural correlates of anosognosia. We assessed local functional coupling and between-network connectivity through between-group intrinsic local correlation and independent component analyses. The neural correlates of anosognosia were assessed via voxel-wise linear regression analysis in prodromal AD. Statistical significance for the FC analysis was set at p ≤ 0.05 false discovery rate (FDR)-corrected for cluster size. One hundred and twenty-one and 73 participants were included in the FC and the anosognosia analysis, respectively. The FC in the default mode network is greater in prodromal AD than AD with dementia (i.e., local correlation: T = 8.26, p-FDR < 0.001, k = 1179; independent component analysis: cerebellar network, T = 4.01, p-FDR = 0.0012, k = 493). The default mode network is persistently affected in the early stages of Alzheimer's biological continuum. The anterior cingulate cortex (T = 2.52, p-FDR = 0.043, k = 704) is associated with anosognosia in prodromal AD.

The Association Between Impaired Awareness and Depression, Anxiety, and Apathy in Mild to Moderate Alzheimer's Disease: A Systematic Review

Objectives: Impaired awareness of cognitive and functional deficits is a common feature of Alzheimer's disease (AD). Although a lack of awareness has been suggested to be a protective factor against experiencing affective symptoms, such as depression, anxiety, and apathy which are common in AD, there is conflicting evidence about the links between them. This systematic review examines the evidence for an association between impaired awareness and depressive, anxiety, and apathy symptoms in mild to moderate AD. Method: We searched four databases (OvidMedline, Embase, PsycInfo, and PsycArticles) using terms encompassing awareness, apathy, depression, anxiety, and mild-moderate AD. We included studies that assessed the relationship between awareness and depressive symptoms, anxiety symptoms, or apathy. We assessed included papers for quality and report results using a narrative approach, prioritizing high quality studies. Results: We identified 1,544 articles, and twenty-seven studies fulfilled inclusion criteria (high-quality = 15; moderate-quality = 12). Most high-quality studies reported that impaired awareness in early-stage AD is cross-sectionally linked with fewer depressive symptoms and anxiety symptoms (correlation ranged from -0.3 to -0.7), but with more apathy. Conclusions: High-quality studies suggested that in people with early AD, impaired awareness is related to fewer depressive and anxiety symptoms and to more apathy. Future research should focus on elucidating causality among impaired awareness and these symptoms in AD.

"Together Make a Visit; Together Make a Plan": Messaging to Adult Children with Concerns about a Parent's Memory Loss

Using the integrative model (IM), we developed and tested messages to encourage adults to accompany their parent to a memory doctor for a cognitive evaluation. We conducted in-depth interviews (n = 60) with African American and White adults with a parent age 65+ to identify key beliefs. Next, we carried out an IM-based telephone survey with a representative sample of the target population (n = 541). Analyses revealed that attitudes varied depending on the gender of the parent. Resulting messages featuring mothers countered the fear of hearing bad news and the belief that mother does not want to be accompanied to the doctor's office. Messages featuring fathers highlighted the belief that attending a doctor's visit will provide father emotional support. We subsequently tested messages with focus group participants (n = 48) and refined them. This study advances our understanding of opportunities to communicate about memory loss, including Alzheimer's disease and dementia, in ways that encourage a behavioral action that will benefit older adults and their families.

Functional and Pathological Correlates of Judgments of Learning in Cognitively Unimpaired Older Adults

Judgments of learning (JOL) pertain to introspective metamemory processes evaluating how well information is learned. Using a functional magnetic resonance imaging (fMRI) task, we investigated the neural substrates of JOL predictions in a group of 105 cognitively unimpaired older adults from the Harvard Aging Brain Study. Associations of JOL performance and its neural correlates with amyloid-β (Aβ) and tau pathology, two proteinopathies associated with Alzheimer's disease (AD) and aging, were also examined. We found that trials judged as learned well relative to trials judged as learned less well (high JOL > low JOL) engaged the ventromedial prefrontal cortex and precuneus, among other midline regions, in addition to bilateral hippocampi. In this cohort of older adults, greater levels of entorhinal tau deposition were associated with overestimation of memory performance and with lower fMRI signal in midline regions during predicted memory success. No associations with Aβ were found. The findings suggest that tau pathology in unimpaired older adults may play a role in altered metamemory processes. We discuss our findings in light of the hypothesis that JOLs are partially dependent on a process involving attempts to retrieve a correct answer from memory, as well as implications for clinical research investigating unawareness of memory performance (i.e., anosognosia) in patients with AD dementia.

Anosognosia Is Associated With Greater Caregiver Burden and Poorer Executive Function in Huntington Disease

BACKGROUND

Anosognosia, or unawareness of one's deficits, is estimated to occur in 25% to 50% of Huntington disease (HD). The relationship between anosognosia and increased caregiver burden found in other dementias has not been determined in HD.

METHODS

Patient-caregiver dyads presenting to a statewide HD clinic were assessed using the Anosognosia Scale and grouped into "anosognosia" and "no anosognosia." Caregiver burden, measured by Zarit Burden Interview (ZBI) and Caregiver Burden Inventory (CBI), demographic data, and Unified Huntington's Disease Rating Scale, including Mini-Mental State Examination, Stroop, Trail Making, Verbal Fluency, and Symbol Digit Modalities Tests, were compared between groups.

RESULTS

Of the 38 patients recruited, 10 (26.3%) met criteria for anosognosia. Patients with anosognosia elicited higher caregiver burden ratings on both the ZBI (mean difference 16.4 [12.1], P < .001) and CBI (16.7 [15.0], P < .005) while also demonstrating poorer executive function. Except for CAG burden score, between-group characteristics did not differ significantly. Stroop Interference predicted both anosognosia and caregiver burden.

CONCLUSIONS

In HD, anosognosia is associated with greater caregiver burden and executive deficits. Its occurrence should prompt further patient assessment and increased caregiver support.

Self- and Informant-Reported Memory Complaints: Frequency and Severity in Cognitively Intact Individuals and those with Mild Cognitive Impairment and Neurodegenerative Dementias

BACKGROUND

Subjective memory complaints (SMCs) are incorporated into the diagnosis of mild cognitive impairment (MCI) and neurodegenerative dementias; however, the relative frequency of SMCs in cognitively intact older adults and those with different types of dementia is poorly understood. Similarly, the concordance between self- versus informant-reported SMCs has not been compared across different diagnostic groups.

OBJECTIVE

This study aimed to evaluate the frequency of self-reported (Objective 1) and informant-reported (Objective 2) SMCs in cognitively intact adults or those diagnosed with MCI or a neurodegenerative dementia. Agreement between participant and informant complaints was also evaluated (Objective 3).

METHODS

Baseline evaluation data were drawn from 488 participants (Mage = 70.49 years; Medu = 15.62 years) diagnosed as cognitively intact, non-amnestic MCI, amnestic single domain MCI, amnestic multi-domain MCI, possible/probable Alzheimer's disease, dementia with Lewy bodies, or frontotemporal dementia. Participants and their informants completed the Memory Assessment Clinic Questionnaire.

RESULTS

One-way ANCOVAs controlling for age, education, and depression revealed no group differences in severity of self-reported SMCs. In contrast, informant memory ratings followed the expected clinical pattern, with comparable and most impaired ratings given to participants with any dementia diagnosis, followed by those with any MCI diagnosis, followed by cognitively intact participants. There was inconsistent agreement between self- and informant-reported SMC ratings in any of the impaired groups.

CONCLUSIONS

Given greater diagnostic specificity and internal consistency of informant report, clinicians should weigh this information more heavily than self-report in the diagnostic process.

Clinical Considerations in Physician-Assisted Death for Probable Alzheimer's Disease: Decision-Making Capacity, Anosognosia, and Suffering

Background

Requests for physician-assisted death (PAD) in patients with cognitive impairment are complex and require careful consideration. Of particular difficulty is determination of whether the request is voluntary and well considered.

Results

Euthanasia and physician-assisted suicide (PAS) are both legal in The Netherlands, Luxemburg, Colombia, and Canada. Euthanasia is legal in Belgium, while PAS is legal in Switzerland and Oregon, Washington, Montana, Vermont, and California (USA). Upon a PAD request, evaluation of the capacity to consent medical treatment is relevant for the decision-making process, while evaluation of testamentary capacity is appropriate before an advance euthanasia directive is written. Anosognosia assessment throughout the Alzheimer's disease continuum provides essential and relevant information regarding the voluntary and well-considered nature of the PAD request; meanwhile, early assessment of hypernosognosia or subjective cognitive decline assists in formulation of a clinical prognosis. Furthermore, the assessment of physical and psychological suffering should incorporate verbal and nonverbal cues as well as consideration of the psychosocial factors that might affect due care criteria.

Conclusion

The clinical approach to a PAD request should consider the legal framework and the decision-making capacity, assess memory deficit awareness and the perception of suffering, and evaluate mental competency when considered pertinent.

Functional Neural Correlates of Anosognosia in Mild Cognitive Impairment and Alzheimer's Disease: a Systematic Review

Functional neuroimaging techniques (i.e. single photon emission computed tomography, positron emission tomography, and functional magnetic resonance imaging) have been used to assess the neural correlates of anosognosia in mild cognitive impairment (MCI) and Alzheimer's disease (AD). A systematic review of this literature was performed, following the Preferred Reporting Items for Systematic Reviews and Meta Analyses statement, on PubMed, EMBASE, and PsycINFO databases. Twenty-five articles met all inclusion criteria. Specifically, four brain connectivity and 21 brain perfusion, metabolism, and activation articles. Anosognosia is associated in MCI with frontal lobe and cortical midline regional dysfunction (reduced perfusion and activation), and with reduced parietotemporal metabolism. Reduced within and between network connectivity is observed in the default mode network regions of AD patients with anosognosia compared to AD patients without anosognosia and controls. During initial stages of cognitive decline in anosognosia, reduced indirect neural activity (i.e. perfusion, metabolism, and activation) is associated with the cortical midline regions, followed by the parietotemporal structures in later stages and culminating in frontotemporal dysfunction. Although the current evidence suggests differences in activation between AD or MCI patients with anosognosia and healthy controls, more evidence is needed exploring the differences between MCI and AD patients with and without anosognosia using resting state and task related paradigms.

Repressive Coping Does Not Contribute to Anosognosia in First-Diagnosis Patients With Alzheimer Disease

Anosognosia is common in patients with Alzheimer disease (AD) even in early stages. Although neural correlates and the impact of cognitive dysfunctions have been described, possible psychodynamic processes such as a repressive coping style as described in other illnesses, have not been examined. Our study aimed to examine possible psychological influence factors on illness perception embracing a repressive coping style and cognitive functions in AD patients in the diagnostic process. Fifty-four subjects with mild AD diagnosed in our memory clinic were enrolled. Anosognosia was evaluated using a patient-caregiver discrepancy rating. All patients underwent comprehensive neuropsychological testing. In addition, characteristics of a repressive coping style were assessed. In total, 79.6% of our patients showed a lack of awareness at least to some degree. 33.3% of the patients were classified as repressors. Repressors and nonrepressors did not differ in cognition, or the unawareness score. Multivariate regression analysis showed that repressive coping style did not significantly contribute to anosognosia, but that verbal memory and naming ability had a strong influence. Although our data indicate that a high proportion of patients with mild AD show characteristics of repressive coping, this possible defense mechanism had no influence on the awareness of illness-related deficits measured by caregiver patient discrepancy.

Awareness of Mild Cognitive Impairment and Mild Alzheimer's Disease Dementia Diagnoses Associated With Lower Self-Ratings of Quality of Life in Older Adults

Objective

This study examined how awareness of diagnostic label impacted self-reported quality of life (QOL) in persons with varying degrees of cognitive impairment.

Method

Older adults (n = 259) with normal cognition, Mild Cognitive Impairment (MCI), or mild Alzheimer's disease dementia (AD) completed tests of cognition and self-report questionnaires that assessed diagnosis awareness and multiple domains of QOL: cognitive problems, activities of daily living, physical functioning, mental wellbeing, and perceptions of one's daily life. We compared measures of QOL by cognitive performance, diagnosis awareness, and diagnostic group.

Results

Persons with MCI or AD who were aware of their diagnosis reported lower average satisfaction with daily life (QOL-AD), basic functioning (BADL Scale), and physical wellbeing (SF-12 PCS), and more difficulties in daily life (DEM-QOL) than those who were unaware (all p ≤ .007). Controlling for gender, those expecting their condition to worsen over time reported greater depression (GDS), higher stress (PSS), lower quality of daily life (QOL-AD, DEM-QOL), and more cognitive difficulties (CDS) compared to others (all p < .05).

Discussion

Persons aware of their diagnostic label-either MCI or AD-and its prognosis report lower QOL than those unaware of these facts about themselves. These relationships are independent of the severity of cognitive impairment.

Integrating the Constructs of Anosognosia and Metacognition: a Review of Recent Findings in Dementia

The current review integrates recent findings regarding the construct of self-awareness in dementia from both clinical and cognitive perspectives. We present the predominant theoretical models of awareness and summarize both traditional and emerging approaches to assessing awareness from clinical and meta-cognitive perspectives. In this review, we focus primarily on findings from recent studies in anosognosia and meta-cognition in the context of neurodegenerative disease with special emphasis on Alzheimer's disease and frontotemporal dementia. Emerging trends in the study of awareness, including examination of the longitudinal course of anosognosia, and investigation of the neural substrates underlying meta-cognitive abilities are addressed. Finally, the practical importance of studying and assessing awareness from both theoretical and clinical angles is emphasized.

Interaction Effect of Awareness and Educational Attainment on the Benefits of Multicomponent Intervention for Persons with Mild Alzheimer's Disease

OBJECTIVE

The study investigated the effect of education on cognitive outcome following a multicomponent intervention program (MIP) for people with Alzheimer's disease (AD), also exploring the additional effect of level of awareness.

METHODS

Fifty-five participants with mild AD were randomized to an MIP (intervention group; IG) or a waiting-list (WL) group. They were further stratified into 4 groups by educational attainment (high vs. low) and level of awareness (aware [IGU-] vs. unaware [IGU+]). MIP efficacy in the different groups was measured using the mean change scores (MCSs) in the Cognitive subscale of Alzheimer's disease Assessment Scale, with pre- and post-treatment testing.

RESULTS

A negative correlation was found between educational level and the MCS in the IG, whereas the correlation in the WL group was positive. Moreover, an interaction effect emerged between education and awareness. Here, in the group of aware individuals, those with high education benefited more from the intervention than those with low education. This difference was not observed in the unawareness group.

CONCLUSION

Higher education may diminish the progression of cognitive decline after MIP, but this potentially depends on the level of awareness.
