RESUMO

Objectives: To investigate the patterns of impairment in decision-making abilities and their relationship with cognitive and clinical symptoms in people with Alzheimer's disease. We hypothesized that decision-making abilities would not be impaired at the same level and would be related to impairment of global cognition and other clinical symptoms of the disease. Methods: Using a cross-sectional design, we included a consecutive sample of 102 people with Alzheimer's disease and their respective caregivers. We investigated the relationship between decision-making capacity and quality of life (QoL), disease awareness, mood, functionality, neuropsychiatric symptoms, and cognition. Results: Different levels of impairment were observed in the participants' decision-making abilities. Understanding, appreciation, and reasoning were correlated, but expressing a choice was only correlated with appreciation. Deficits in understanding were related to impaired disease awareness, lower self-reported QoL, and lower comprehension of spoken language. Better appreciation was related to better orientation and lower age. Better reasoning was related to better orientation and better self-reported QoL. Deficits in expressing a choice were related to lower self-reported QoL. Conclusion: The pattern of impairment in decision-making abilities was not linear. Each decision-making ability was related to different cognitive and clinical deficits. Therefore, cognitive functioning is an insufficient criterion for judging an individual's decision-making ability.

RESUMO

OBJECTIVE: Cognitive, neuropsychiatric and functional deficits are core symptoms of dementia. Non- -pharmacological interventions, such as music therapy, when used in conjunction with pharmacological treatment, have the potential to alleviate these symptoms. The purpose of this preliminary study is to examine the active music therapy on cognition and neuropsychiatric symptoms in the elderly with mild and moderate dementia. METHODS: The initial sample consisted of outpatients with dementia (N = 15) and their family members or caregivers (N = 15). Two dyads did not complete the assessments before intervention and were excluded from the analysis. Thirteen females (N = 13) comprised the final sampled and were diagnosed with Alzheimer's disease (N = 10), vascular dementia (N = 2) and mixed dementia (N = 1), at mild (N = 11) and moderate (N = 2) dementia stage. Participants were enrolled in an open-label trial of active music therapy group, set to take place once weekly for 60 minutes over a period of 12 weeks. RESULTS: Participants experienced a slight improvement on cognition measured with Mini-Mental State Examination (p = 0.41), although without statistical significance and a statistically significant decrease in anxiety (p = 0.042) in post-intervention. There were no significant effects on quality of life and caregiver burden. CONCLUSIONS: Active music therapy is a promising intervention with good acceptance among participants. More studies with larger sample sizes are needed to confirm its effects and efficacy in cognitive and neuropsychiatric symptoms in dementia.

OBJETIVO: Distúrbios cognitivos, comportamentais e funcionais são sintomas nucleares na demência. Intervenções não farmacológicas, como a musicoterapia, quando usadas em conjunto com o tratamento farmacológico, têm o potencial de aliviar esses sintomas. O objetivo deste estudo preliminar é examinar a musicoterapia ativa na cognição e nos sintomas neuropsiquiátricos em idosos com demência leve e moderada. MÉTODOS: A amostra inicial foi composta por pacientes ambulatoriais com demência (N = 15) e seus familiares ou cuidadores (N = 15). Duas duplas não completaram as avaliações antes da intervenção e foram excluídas da análise. Treze mulheres (N = 13) compuseram a amostra final e foram diagnosticadas com doença de Alzheimer (N = 10), demência vascular (N = 2) e demência mista (N = 1), nos estágios leve (N = 11) e moderado (N = 2). Os participantes foram inscritos em um estudo aberto de grupo de musicoterapia ativa, programado para ocorrer uma vez por semana, com duração de 60 minutos, durante o período de 12 semanas. RESULTADOS: Os participantes experimentaram uma discreta melhora cognitiva medida pelo Miniexame do Estado Mental (p = 0.41), embora sem significância estatística, e uma diminuição estatisticamente significativa na ansiedade (p = 0.042) na pós-intervenção. Não houve efeitos significativos na qualidade de vida e sobrecarga do cuidador. CONCLUSÕES: A musicoterapia ativa é uma intervenção promissora, com boa aceitação entre os participantes. Mais estudos com amostras maiores são necessários para confirmar seus efeitos e eficácia em sintomas cognitivos e neuropsiquiátricos na demência.

RESUMO

INTRODUCTION: Resilience is a dynamic process that acts to modify the effects of an adverse life event. In this study, we aimed to test the construct validity of the Resilience Scale by employing exploratory and confirmatory procedures, and to investigate the relationship between caregiver's resilience and clinical status of people with Alzheimer's disease. METHODS: A sample of 143 dyads of people with Alzheimer's disease and their primary caregivers were included. RESULTS: The total Resilience Scale mean score was 140.3 (standard deviation [SD] = 16.289), ranging from 25 to 175, indicating a high level of resilience. Cronbach's alpha was high (α = 0.77), indicating excellent internal consistency. The mean of corrected item-total correlation coefficients was moderate. The Resilience Scale presented a four-factor solution with a well-defined structure: sense of life and self-sufficiency, perseverance, self-confidence and equanimity, and meaningfulness. CONCLUSION: The findings indicate excellent internal consistency of the Resilience Scale when used to evaluate psychological and emotional difficulties of caregivers, even though the correlations observed between the Resilience Scale and clinical variables were not significant for functionality, mood, awareness, neuropsychiatric symptoms, or burden.

RESUMO

INTRODUCTION: Compared to other types of caregiver, spouse-caregivers tend to be closer to people with Alzheimer's disease (PwAD) because of their different position in the relationship. We designed this study to compare the differences in caregivers' quality of life (QoL) and domains of QoL according to the kinship relationship between the members of caregiving dyads. METHODS: We assessed QoL of 98 PwAD and their family caregivers (spouse-caregivers, n = 49; adult children, n = 43; and others, n = 6). The PwAD and their caregivers completed questionnaires about their QoL, awareness of disease, cognition, severity of dementia, depression, and burden of caring. RESULTS: The comparison between caregiver types showed that spouse-caregivers were older, with higher levels of burden and lower scores for cognition. Caregivers' total QoL scores were not significantly different according to type of kinship. However, there were significant differences in the domains physical health (p = 0.04, Cohen's d [d] = -0.42), marriage (p = 0.01, d = 1.31), and friends (p = 0.04, d = -0.41), and life as a whole showed a trend to difference (p = 0.08, d = -0.33). When QoL domains were analyzed within dyads, there were significant differences between members of spouse dyads in the domains energy (p = 0.01, d = -0.49), ability to do things for fun (p = 0.01, d = -0.48), and memory (p = 0.000, d = -1.07). For non-spouse dyads, there were significant differences between caregivers and PwAD for the QoL domains memory (p = 0.004, d = -0.63), marriage (p = 0.001, d = -0.72), friends (p = 0.001, d = -0.65), and ability to do chores (p = 0.000, d = -0.76). CONCLUSIONS: Differences were only detected between spouse/non-spouse-caregivers when QoL was analyzed by domains. We speculate that spouse and non-spouse caregivers have distinct assessments and perceptions of what is important to their QoL.

RESUMO

Objectives: To investigate the resilience of caregivers of people with mild and moderate Alzheimer's disease (PwAD) and the related sociodemographic and clinical characteristics.Methods: Cross-sectional assessment of dyads of PwAD and family caregivers (N = 106). Caregivers were assessed for resilience, depression, anxiety, hopelessness, quality of life, burden and cognition. PwAD were assessed for severity of dementia, cognition, neuropsychiatric symptoms, functionality, quality of life and awareness of disease.Results: Most of the caregivers (51.1%) reported emotional problems (symptoms of anxiety, stress and depression). In both mild (p < 0.05) and moderate (p < 0.05) PwAD groups, resilience was inversely related to self-reported emotional problems. There was not a significant difference between caregivers of mild and moderate PwAD resilience (p < 0.05). Upon analyzing the factors related to resilience, we found some differences between the groups of caregivers of mild and moderate PwAD. Neuropsychiatric symptoms of PwAD (p < 0.05) and caregiver's depressive symptoms (p < 0.05) were related to resilience of caregivers of mild PwAD. In the moderate group, caregivers' higher levels of quality of life (p < 0.05) and co-residing with PwAD (p < 0.05) were related to resilience.Conclusion: Caregivers' resilience is driven by different factors according to disease severity. The findings suggest that resilience allows caregivers to manage and respond positively to stressful demands of care.

RESUMO

Facial expression recognition is one of the essential abilities for social cognition. We aimed to compare facial expression recognition among people with mild and moderate Alzheimer's disease (AD) and to identify which factors were associated with impairment according to disease severity. We included 52 participants with either mild or moderate AD. FACES includes four subtasks requiring matching expressions with picture stimuli (tasks 1 and 2), labelling emotions (task 3), and recognizing situations with evident emotional content (task 4). There were significant differences between groups in FACES global scores, task 2 and task 4. In the mild AD group, FACES global score was influenced by educational background and cognitive performance, task 1 was associated with comprehension and constructive praxis, task 2 was associated with cognitive flexibility, and task 3 was associated with word finding. In subtask 4, no significant associations were found after adjusting for level of cognitive decline. In the moderate AD group, the awareness of emotional state domain was associated with FACES global score, task 1 was associated with constructive praxis, task 3 was associated with neuropsychiatric symptoms, and task 4 was associated with the ability to recognize emotions through situations. No significant associations were found on task 2, after adjusting for level of cognitive decline. Our findings suggest emotional processing difficulties across AD stages. However, when participants needed to recognize the most preponderant emotion in a situation with evident emotional content, our results suggest that in both groups there was no influence of cognitive impairment.

RESUMO

ABSTRACT Objective: We adapted the MacArthur Competence Assessment Tool for Treatment (MacCAT-T) to Brazilian Portuguese, pilot testing it on mild and moderate patients with Alzheimer's disease (AD). Methods: The cross-cultural process required six steps. Sixty-six patients with AD were assessed for competence to consent to treatment, global cognition, working memory, awareness of disease, functionality, depressive symptoms and dementia severity. Results: The items had semantic, idiomatic, conceptual and experiential equivalence. We found no difference between mild and moderate patients with AD on the MacCAT-T domains. The linear regressions showed that reasoning (p = 0.000) and functional status (p = 0.003) were related to understanding. Understanding (p = 0.000) was related to appreciation and reasoning. Awareness of disease (p = 0.001) was related to expressing a choice. Conclusions: The MacCAT-T adaptation was well-understood and the constructs of the original version were maintained. The results of the pilot study demonstrated an available Brazilian tool focused on decision-making capacity in AD.

RESUMO Objetivo: Adaptamos o MacArthur Competence Assessment Tool for Treatment (MacCAT-T) para o português brasileiro, realizando estudo piloto em amostra de pessoas com doença de Alzheimer (DA) leve e moderada. Métodos: O processo transcultural apresentou seis passos. Posteriormente, avaliamos competência para consentimento do tratamento, cognição global, memória de trabalho, consciência da doença, funcionalidade, sintomas depressivos e gravidade da doença de 66 pessoas com DA. Resultados: Os itens apresentaram equivalência semântica, idiomática, conceitual e experiencial. Não encontramos diferenças entre pessoas com DA leve e moderada nos domínios do MacCAT-T. Regressões lineares demonstraram que raciocínio (p = 0.000) e funcionalidade (p = 0.003) estavam relacionados à compreensão. Compreensão (p = 0.000) estava relacionada ao julgamento e raciocínio. Consciência da doença (p = 0.001) estava relacionada à expressão da escolha. Conclusões: A adaptação da MacCAT-T foi bem compreendida e os constructos da versão original mantidos. Resultados do estudo piloto apontaram disponibilidade de ferramenta brasileira sobre tomada de decisões na DA.

RESUMO

Resilience is the capacity for successful adaptation when faced with the stress of adversity. We aimed to investigate the relationship between caregivers' resilience and the sociodemographic and clinical factors of people with dementia. Cross-sectional assessment of 58 people with dementia and their caregiver dyads showed that most caregivers were female adult children. The caregivers reported moderate to higher levels of resilience, lower levels of anxiety and depressive symptoms and moderate levels of burden. Resilience was not related to the caregiver's gender (p = 0.883), nor clinical (p = 0.807) or emotional problems (p = 0.420). The regression showed that resilience was related to the caregiver's quality of life (p < 0.01) and inversely associated with their depressive symptoms (p < 0.01). There was no relationship between caregivers' resilience and the sociodemographic and clinical characteristics of people with dementia. We can assume that resilience is an individual characteristic. Support groups should also focus on the factors that may increase resilience among caregivers.

RESUMO Resiliência é a capacidade de adaptação bem-sucedida, quando confrontado com o estresse da adversidade. Nosso objetivo foi investigar a relação entre a resiliência dos cuidadores e fatores sociodemográficos e clínicos de pessoas com demência. A avaliação transversal de 58 pessoas com demência e suas duplas de cuidadores, mostrou que a maioria dos cuidadores eram do sexo feminino e filhas adultas. Os cuidadores relataram níveis moderados a altos de resiliência, níveis mais baixos de ansiedade e sintomas depressivos e níveis moderados de sobrecarga. Resiliência não estava relacionada ao gênero (p = 0.883) e problemas clínicos (p = 0.807) e emocionais (p = 0.420) dos cuidadores. A regressão mostrou que a resiliência foi relacionada à qualidade de vida (p < 0,01) dos cuidadores e inversamente associada com os sintomas depressivos (p < 0,01). Não havia uma relação significativa entre a resiliência dos cuidadores e as características sociodemográficos e clínicas das pessoas com demência. Podemos supor que a resiliência é uma característica individual. Os grupos de apoio devem enfatizar os fatores que podem aumentar a resiliência entre os cuidadores.
