RESUMO

OBJECTIVE: We aimed to explore the construct of "high need" and identify common need domains among high-need patients, their care professionals, and healthcare organizations; and to describe the interventions that health care systems use to address these needs, including exploring the potential unintended consequences of interventions. METHODS: We conducted a modified Delphi panel informed by an environmental scan. Expert stakeholders included patients, interdisciplinary healthcare practitioners (physicians, social workers, peer navigators), implementation scientists, and policy makers. The environmental scan used a rapid literature review and semi-structured interviews with key informants who provide healthcare for high-need patients. We convened a day-long virtual panel meeting, preceded and followed by online surveys to establish consensus. RESULTS: The environmental scan identified 46 systematic reviews on high-need patients, 19 empirical studies documenting needs, 14 intervention taxonomies, and 9 studies providing construct validity for the concept "high need." Panelists explored the construct and terminology and established that individual patients' needs are unique, but areas of commonality exist across all high-need patients. Panelists agreed on 11 domains describing patient (e.g., social circumstances), 5 care professional (e.g., communication), and 8 organizational (e.g., staffing arrangements) needs. Panelists developed a taxonomy of interventions with 15 categories (e.g., care navigation, care coordination, identification and monitoring) directed at patients, care professionals, or the organization. The project identified potentially unintended consequences of interventions for high-need patients, including high costs incurred for patients, increased time and effort for care professionals, and identification of needs without resources to respond appropriately. CONCLUSIONS: Care for high-need patients requires a thoughtful approach; differentiating need domains provides multiple entry points for interventions directed at patients, care professionals, and organizations. Implementation efforts should consider outlined intended and unintended downstream effects on patients, care professionals, and organizations.

RESUMO

BACKGROUND: Healthcare systems are increasingly implementing programs for high-need patients, who often have multiple chronic conditions and complex social situations. Little, however, is known about quality indicators that might guide healthcare organizations and providers in improving care for high-need patients. We sought to conduct a systematic review to identify potential quality indicators for high-need patients. METHODS: This systematic review (CRD42020215917) searched PubMed, CINAHL, and EMBASE; guideline clearing houses ECRI and GIN; and Google scholar. We included publications suggesting, evaluating, and utilizing indicators to assess quality of care for high-need patients. Critical appraisal of the indicators addressed the development process, endorsement and adoption, and characteristics, such as feasibility. We standardized indicators by patient population subgroups to facilitate comparisons across different indicator groups. RESULTS: The search identified 6964 citations. Of these, 1382 publications were obtained as full text, and 53 studies met inclusion criteria. We identified over 1700 quality indicators across studies. Quality indicator characteristics varied widely. The scope of the selected indicators ranged from detailed criterion (e.g., "annual eye exam") to very broad categories (e.g., "care coordination"). Some publications suggested disease condition-specific indicators (e.g., diabetes), some used condition-independent criteria (e.g., "documentation of the medication list in the medical record available to all care agencies"), and some publications used a mixture of indicator types. DISCUSSION: We identified and evaluated existing quality indicators for a complex, heterogeneous patient group. Although some quality indicators were not disease-specific, we found very few that accounted for social determinants of health and behavioral factors. More research is needed to develop quality indicators that address patient risk factors.

RESUMO

OBJECTIVE: Impaired empathy is a core feature of behavioral variant frontotemporal dementia (bvFTD). Patients with bvFTD are also prominently impaired in experiencing self-conscious emotions. The investigators explored whether impaired empathy in bvFTD, such as self-conscious emotions, may result from impaired self-consciousness in social situations (socioemotional self-perception). METHODS: This pilot study evaluated 25 patients with bvFTD and compared them with 25 patients with Alzheimer's disease who had comparable dementia severity. Their caregivers completed the Social Dysfunction Scale (SDS), which quantifies empathy, and an extensive intake interview that included questions regarding self-consciousness and insight. The patients completed two measures of self-perception in social situations, the Schutte Self-Report Emotional Intelligence Test (SSEIT) scale and the Embarrassability Scale (EMB). RESULTS: Caregivers of patients with bvFTD, but not of patients with Alzheimer's disease, reported a high correlation between significantly decreased empathy (SDS) and decreased self-consciousness (intake interview questions). Consistent with lack of insight, the patients with bvFTD, unlike the patients with Alzheimer's disease, did not report decreases on the SSEIT and EMB measures. CONCLUSIONS: These preliminary findings suggest that impaired socioemotional self-perception plays a role in the loss of empathy among patients with bvFTD. A lack of self-consciousness in social situations may contribute to a loss of empathy resulting from an inability to co-represent another's emotion in relation to oneself.

RESUMO

BACKGROUND: Neuropsychiatric symptoms can impact decision-making in patients with Alzheimer disease (AD). METHODS: Using a simple decision-making task, a variant of the ultimatum game (UG) modified to control feelings of unfairness, this study investigated rejection responses among responders to unfair offers. The UG was administered to 11 patients with AD, 10 comparably demented patients with behavioral variant frontotemporal dementia (bvFTD), and 9 healthy controls (HC). The results were further compared with differences on the caregiver Neuropsychiatric Inventory (NPI). RESULTS: Overall, patients with AD significantly rejected more total offers than did the patients with bvFTD and the HC (P < .01). On the NPI, the only domain that was significantly worse among the patients with AD compared to the other groups was dysphoria/depression. CONCLUSIONS: These results suggest that early AD can be distinguished based on increased rejections of offers in decision-making, possibly consequent to a heightened sense of unfairness from dysphoria/depression.

RESUMO

OBJECTIVE: The experience of embarrassment signals violations in social norms, and impairment in this social emotion may underlie much of the social dysfunction in behavioral variant frontotemporal dementia (bvFTD). The authors investigated whether impaired self-awareness of embarrassment may distinguish patients with bvFTD early in the course of disease from healthy control subjects (HCs). METHODS: Self-reported embarrassment was examined among 18 patients with early bvFTD and 23 HCs by using the 36-item Embarrassability Scale, which includes items of situations eliciting embarrassment for oneself ("self-embarrassment") and embarrassment for others ("vicarious embarrassment"). The two study groups were also compared with the Social Norms Questionnaire (SNQ). The analyses included correlations of SNQ results (total score, violations or "break" errors, and overendorsement of social rules or "overadhere" errors) with Embarrassability Scale scores. RESULTS: Patients with bvFTD did not differ from HCs on total or self-embarrassment scores but did have significantly higher vicarious embarrassment scores. Unlike in the HC group, reports of vicarious embarrassment did not differ from reports of self-embarrassment among patients in the bvFTD group. The Embarrassability Score further correlated with overadherence to norms on the SNQ. CONCLUSIONS: In the presence of social dysfunction and emotional blunting, these findings suggest that patients with bvFTD rely on their own perspective for a rule-based application of social norms in reporting vicarious embarrassment. The assessment of reports of embarrassment for others may indicate an early and previously unrecognized clinical measure for detecting bvFTD.

RESUMO

OBJECTIVE: Impaired empathy is a diagnostic feature of behavioral variant frontotemporal dementia (bvFTD), but it is not clear whether it is caused by a primary impairment in empathy or by general emotional blunting. METHODS: Patients with bvFTD who met criteria for loss of empathy (N=10) and patients with Alzheimer's disease (N=15) were assessed with a measure for empathy (Socioemotional Dysfunction Scale [SDS]) and a measure for general emotion (Scale for Emotional Blunting [SEB]). All patients underwent neuroimaging. Both patient groups and a healthy control group (N=18) were evaluated by using autonomic responses (skin conductance responses [SCR]) to pictures from the Internal Affective Picture System (IAPS) (presence or absence of empathy stimuli and high versus low emotion). RESULTS: All participants reported understanding the content and others' perspectives on the empathy pictures; however, only patients with bvFTD showed impaired empathic behavior on the SDS, which persisted after adjusting for measures from the emotion scale (SEB). Patients with bvFTD had significantly lower SCR for all the IAPS stimuli, including for empathy pictures, which also persisted after adjusting for emotional content. On MRI analysis, SCR across groups significantly correlated with the volume of the dorsal anterior cingulate gyrus (dACC). CONCLUSIONS: These results indicate that patients with bvFTD have decreased empathic behavior with or without emotional blunting, and they exhibit decreased psychophysiological responses to empathy stimuli, independent of general emotion. These preliminary findings suggest a specific impairment in emotional empathy, possibly related to impairment of the emotional appraisal role of the dACC.

RESUMO

Patients with behavioral variant frontotemporal dementia (bvFTD) and Alzheimer's disease (AD) differ in basic emotional tone. Skin conduction levels (SCLs), a measure of sympathetic tone, may be a sensitive test for discriminating these two dementias early in their course. Previous research has shown differences in resting SCLs between patients with bvFTD and AD, but no study has evaluated the discriminability of SCLs during different environmental conditions. The authors compared bvFTD patients (N=8), AD patients (N=10), and healthy control subjects (N=9) on SCL measures pertaining to real-life vignettes or scenarios differing in valence and emotional intensity. The SCLs among the bvFTD patients were decreased across all conditions, whereas the SCLs among the AD patients were increased compared with control participants. On analysis, the SCLs in response to emotional stimuli differentiated bvFTD from AD with an area under the receiver operator characteristic curve of 95.3%. At a cutoff ≤0.77 µS, emotional vignettes distinguished bvFTD from AD with a sensitivity of 86% and a specificity of 96%. These preliminary results indicate the potential utility of SCLs for differentiating bvFTD from AD early in their course, regardless of environmental condition.

RESUMO

Behavioral variant frontotemporal dementia (bvFTD) is a neurodegenerative disorder with initial disturbances in socioemotional behavior in the absence of a sensitive diagnostic test. This study evaluated Pavlov's "orienting response" (OR) or "what is it?" reflex as a measure of their ability to refocus attention on socioemotional stimuli and as a potentially distinguishing measure for bvFTD. Ten patients with bvFTD were compared with 18 normal controls (NC) on ORs (defined as initial heart rate [HR] deceleration) to different pictures based on social and emotional (valence) differences from the International Affective Picture Stimuli. HR was measured while participants viewed pleasant-nonsocial (e.g., food), unpleasant-nonsocial (e.g., garbage), pleasant-social (e.g., babies), and unpleasant-social (e.g., violence) pictures. Participants watched each picture for 6 seconds, and the study examined HR changes during the first 2-second OR interval. The results showed significant differences in valence (pleasant-unpleasant) and valence-group interactions, but no effects of nonsocial-social. Whereas the NCs showed the expected HR deceleration (OR) to unpleasant stimuli, the bvFTD patients showed increased HRs without an initial refocusing. Decreased HR slowing to stimuli among the bvFTD patients correlated with increased scores on an emotional blunting scale. These findings suggest that decreased socioemotional behavior in bvFTD may be associated with decreased appreciation of emotional aspects of stimuli as evidenced by decreased ORs to emotional stimuli, regardless of social content. These findings also suggest further investigation of the OR in bvFTD as an early diagnostic measure for this disorder.

RESUMO

INTRODUCTION: Socioemotional dysfunction distinguishes behavioural variant frontotemporal dementia (bvFTD) from other dementias. Patients with bvFTD not only have early social impairment and emotional blunting, but they also have agnosia of their socioemotional dysfunction. METHODS: To investigate the relationship between agnosia and dysfunction, we assessed self-knowledge of socioemotional dysfunction with an emotional quotient (EQ) scale administered to 12 patients with bvFTD and a comparison group of 12 age-matched patients with Alzheimer's disease (AD), and compared these self-ratings to caregiver ratings of social dysfunction and emotional blunting. RESULTS: The bvFTD patients self-rated as having higher EQs than the AD patients, particularly higher self-ratings of their Social Skills, an EQ subscale which correlated with increased emotional blunting. On within-groups analysis, the bvFTD patients' high self-ratings of their EQ Appraisal of Emotions correlated with increased socioemotional dysfunction, whereas all of the AD patients' self-ratings correlated appropriately with their degree of dysfunction. CONCLUSIONS: Large socioemotional agnosia scores (EQ minus function) distinguishes bvFTD from AD. Additionally, in bvFTD, agnosia specifically for their ability to appreciate others' emotions correlates with the degree of socioemotional dysfunction, suggesting a role for socioemotional agnosia in increasing socioemotional dysfunction.

RESUMO

In network analysis, the so-called "rich club" describes the core areas of the brain that are more densely interconnected among themselves than expected by chance, and has been identified as a fundamental aspect of the human brain connectome. This is the first in-depth diffusion imaging study to investigate the rich club along with other organizational changes in the brain's anatomical network in behavioral frontotemporal dementia (bvFTD), and a matched cohort with early-onset Alzheimer's disease (EOAD). Our study sheds light on how bvFTD and EOAD affect connectivity of white matter fiber pathways in the brain, revealing differences and commonalities in the connectome among the dementias. To analyze the breakdown in connectivity, we studied three groups: 20 bvFTD, 23 EOAD, and 37 healthy elderly controls. All participants were scanned with diffusion-weighted magnetic resonance imaging (MRI), and based on whole-brain probabilistic tractography and cortical parcellations, we analyzed the rich club of the brain's connectivity network. This revealed distinct patterns of disruption in both forms of dementia. In the connectome, we detected less disruption overall in EOAD than in bvFTD [false discovery rate (FDR) critical Pperm = 5.7 × 10(-3) , 10,000 permutations], with more involvement of richly interconnected areas of the brain (chi-squared P = 1.4 × 10(-4) )-predominantly posterior cognitive alterations. In bvFTD, we found a greater spread of disruption including the rich club (FDR critical Pperm = 6 × 10(-4) ), but especially more peripheral alterations (chi-squared P = 6.5 × 10(-3) ), particularly in medial frontal areas of the brain, in line with the known behavioral socioemotional deficits seen in these patients.

RESUMO

BACKGROUND: While much disinhibition in dementia results from generalized impulsivity, in behavioral variant frontotemporal dementia (bvFTD) disinhibition may also result from impaired social cognition. OBJECTIVE: To deconstruct disinhibition and its neural correlates in bvFTD vs. early-onset Alzheimer's disease (eAD). METHODS: Caregivers of 16 bvFTD and 21 matched-eAD patients completed the Frontal Systems Behavior Scale disinhibition items. The disinhibition items were further categorized into (1) "person-based" subscale which predominantly associated with violating social propriety and personal boundary and (2) "generalized-impulsivity" subscale which included nonspecific impulsive acts. Subscale scores were correlated with grey matter volumes from tensor-based morphometry on magnetic resonance images. RESULTS: In comparison to the eAD patients, the bvFTD patients developed greater person-based disinhibition ( P < 0.001) but comparable generalized impulsivity. Severity of person-based disinhibition significantly correlated with the left anterior superior temporal sulcus (STS), and generalized-impulsivity correlated with the right orbitofrontal cortex (OFC) and the left anterior temporal lobe (aTL). CONCLUSIONS: Person-based disinhibition was predominant in bvFTD and correlated with the left STS. In both dementia, violations of social propriety and personal boundaries involved fronto-parieto-temporal network of Theory of Mind, whereas nonspecific disinhibition involved the OFC and aTL.

RESUMO

BACKGROUND: Clinical research studies of behavioral variant frontotemporal dementia (bvFTD) often use Alzheimer disease (AD) as a comparison group for control of dementia variables, using tests of cognitive function to match the groups. These two dementia syndromes, however, are very different in clinical manifestations, and the comparable severity of these dementias may not be reflected by commonly used cognitive scales such as the Mini-Mental State Examination (MMSE). METHODS: We evaluated different measures of dementia severity and symptoms among 20 people with bvFTD compared to 24 with early-onset AD. RESULTS: Despite similar ages, disease-duration, education, and cognitive performance on two tests of cognitive function, the MMSE and the Montreal Cognitive Assessment (MoCA), the bvFTD participants, compared to the AD participants, were significantly more impaired on other measures of disease severity, including function (Functional Assessment Questionnaire (FAQ)), neuropsychiatric symptoms (Neuropsychiatric Inventory (NPI)), and global dementia stage (Clinical Dementia Rating Scales (CDRs)). However, when we adjusted for the frontotemporal lobar degeneration-CDR (FTLD-CDR) in the analyses, the two dementia groups were comparable across all measures despite significant differences on the cognitive scales. CONCLUSION: We found tests of cognitive functions (MMSE and MoCA) to be insufficient measures for ensuring comparability between bvFTD and AD groups. In clinical studies, the FTLD-CDR, which includes additional language and behavior items, may be a better overall way to match bvFTD and AD groups on dementia severity.

RESUMO

BACKGROUND: Bilingualism may protect against cognitive aging and delay the onset of dementia. However, studies comparing monolinguals and bilinguals on such metrics have produced inconsistent results complicated by confounding variables and methodological concerns. METHODS: We addressed this issue by comparing cognitive performance in a more culturally homogeneous cohort of older Spanish-speaking monolingual (n = 289) and Spanish-English bilingual (n = 339) Mexican-American immigrants from the Sacramento Longitudinal Study on Aging. RESULTS: After adjusting for demographic differences and depressive symptoms, both groups performed similarly at baseline on verbal memory but the bilingual group performed significantly better than the monolingual group on a cognitive screening test, the Modified Mini-Mental State Examination (3MS; p < 0.001). Group differences on the 3MS were driven by language/executive and language/praxis factors. Within the bilingual group, neither language of testing nor degree of bilingualism was significantly associated with 3MS or verbal memory scores. Amongst individuals who performed in the normal or better range on both tests at baseline and were followed for an average of 6 years, both monolinguals and bilinguals exhibited similar rates of cognitive decline on both measures. CONCLUSIONS: These findings suggest that bilingualism is associated with modest benefits in cognitive screening performance in older individuals in cross-sectional analyses that persist across longitudinal analyses. The effects of bilingualism should be considered when cognitively screening is performed in aging immigrant populations.

RESUMO

BACKGROUND: Emotional blunting is a major clinical feature of behavioral variant frontotemporal dementia (bvFTD). Assessing the change in emotional blunting may facilitate the differential diagnosis of this disorder and can quantify a major source of distress for the patients' caregivers and families. METHODS: We evaluated investigator ratings on the Scale for Emotional Blunting (SEB) for 13 patients with bvFTD versus 18 patients with early-onset Alzheimer's disease (AD). The caregivers also performed SEB ratings for both the patients' premorbid behavior (before dementia onset) and the patients' behavior on clinical presentation (after dementia onset). RESULTS: Before the onset of dementia, the caregivers reported normal SEB scores for both dementia groups. After the onset of dementia, both caregivers and investigators reported greater SEB scores for the bvFTD patients compared to the AD patients. The patients were rated to be much more emotionally blunted by the bvFTD caregivers than by the investigators. A change of ≥15 in the caregiver SEB ratings suggests bvFTD. The change in caregiver SEB ratings was positively correlated with bifrontal hypometabolism on FDG-PET scans. CONCLUSIONS: Changes in the caregiver assessment of emotional blunting with dementia onset can distinguish patients with bvFTD from those with AD, and they may better reflect the impact of emotional blunting than similar assessments made by clinicians/investigators.

RESUMO

Emotional blunting is a core diagnostic feature of behavioral variant frontotemporal dementia (bvFTD). The authors evaluated skin conductance as a measure of emotional blunting among 10 patients with bvFTD compared with 10 with Alzheimer's disease and 14 healthy control subjects. Despite responses to an auditory startle stimulus, skin conductance levels (SCLs) were lower in the patients with bvFTD compared with the other groups. The low SCLs significantly correlated with ratings of emotional blunting. The authors conclude that low SCLs in bvFTD indicate a low resting sympathetic state and low emotional arousal. The measurement of SCLs may be a useful noninvasive diagnostic test for bvFTD.

RESUMO

ABSTRACT Background: Caregivers report early disturbances in social behavior among patients with behavioral variant frontotemporal dementia (bvFTD); however, there are few direct observational studies of these social behavioral disturbances. This study aimed to identify social behavioral themes in bvFTD by direct observation in naturalistic interactions. The identification of these themes can help caregivers and clinicians manage the social behavioral disturbances of this disease. Methods: Researchers observed 13 bvFTD patients in their homes and community-based settings and recorded field notes on their interpersonal interactions. A qualitative analysis of their social behavior was then conducted using ATLAS.ti application and a constant comparison method. Results: Qualitative analysis revealed the following themes: (1) diminished relational interest and initiation, indicating failure to seek social interactions; (2) lack of social synchrony/intersubjectivity, indicating an inability to establish and maintain interpersonal relationships; and (3) poor awareness and adherence to social boundaries and norms. These themes corresponded with changes from caregiver reports and behavioral scales. Conclusion: This analysis indicates that real-world observation validates the diagnostic criteria for bvFTD and increases understanding of social behavioral disturbances in this disorder. The results of this and future observational studies can highlight key areas for clinical assessment, caregiver education, and targeted interventions that enhance the management of social behavioral disturbances in bvFTD.

RESUMO

BACKGROUND/AIMS: The clinical syndromes of frontotemporal lobar degeneration include behavioral variant frontotemporal dementia (bvFTD) and semantic (SV-PPA) and nonfluent variants (NF-PPA) of primary progressive aphasia. Using magnetic resonance imaging (MRI), tensor-based morphometry (TBM) was used to determine distinct patterns of atrophy between these three clinical groups. METHODS: Twenty-seven participants diagnosed with bvFTD, 16 with SV-PPA, and 19 with NF-PPA received baseline and follow-up MRI scans approximately 1 year apart. TBM was used to create three-dimensional Jacobian maps of local brain atrophy rates for individual subjects. RESULTS: Regional analyses were performed on the three-dimensional maps and direct comparisons between groups (corrected for multiple comparisons using permutation tests) revealed significantly greater frontal lobe and frontal white matter atrophy in the bvFTD relative to the SV-PPA group (p < 0.005). The SV-PPA subjects exhibited significantly greater atrophy than the bvFTD in the fusiform gyrus (p = 0.007). The NF-PPA group showed significantly more atrophy in the parietal lobes relative to both bvFTD and SV-PPA groups (p < 0.05). Percent volume change in ventromedial prefrontal cortex was significantly associated with baseline behavioral symptomatology. CONCLUSION: The bvFTD, SV-PPA, and NF-PPA groups displayed distinct patterns of progressive atrophy over a 1-year period that correspond well to the behavioral disturbances characteristic of the clinical syndromes. More specifically, the bvFTD group showed significant white matter contraction and presence of behavioral symptoms at baseline predicted significant volume loss of the ventromedial prefrontal cortex.

RESUMO

INTRODUCTION: Injuries from explosive devices can cause blast-force injuries, including mild traumatic brain injury (mTBI). OBJECTIVE: This study investigated changes in personality from blast-force mTBI in comparison to blunt-force mTBI. METHODS: Clinicians and significant others assessed US veterans who sustained pure blast-force mTBI (n = 12), as compared to those who sustained pure blunt-force mTBI (n = 12). Inclusion criteria included absence of any mixed blast-blunt trauma and absence of post-traumatic stress disorder. Measures included the Interpersonal Measure of Psychopathy (IM-P), the Big Five Inventory (BFI), the Interpersonal Adjectives Scale (IAS) and the Frontal Systems Behaviour Scale (FrSBe). RESULTS: There were no group differences on demographic or TBI-related variables. Compared to the Blunt Group, the Blast Group had more psychopathy on the IM-P, with anger, frustration, toughness and boundary violations and tended to more neuroticism on the BFI. When pre-TBI and post-TBI assessments were compared on the IAS and FrSBe, only the patients with blast force mTBI had become more cold-hearted, aloof-introverted and apathetic. CONCLUSION: These results suggest that blast forces alone can cause negativistic behavioural changes when evaluated with selected measures of personality. Further research on isolated blast-force mTBI should focus on these personality changes and their relationship to blast over-pressure.

RESUMO

Intensive management programs may improve health care experiences among high-risk and complex patients. We assessed patient experience among (1) prior enrollees (n = 59) of an intensive management program (2014-2018); (2) nonenrollees (n = 356) at program sites; and (3) nonprogram site patients (n = 728), using a patient survey based on the Consumer Assessment of Healthcare Providers and Systems in 2019. Outcomes included patient ratings of patient-centered care; overall health care experience; and satisfaction with their usual outpatient care provider. In multivariate models, enrollees were more satisfied with their current provider versus nonenrollees within program sites (adjusted odds ratio 2.36; 95% confidence interval 1.15-4.85).
