Measures of Awareness in Alzheimer's Disease and Clinical Differences Between Groups with Preserved, Impaired, and Absent Awareness.

Background: Awareness is a heterogeneous construct that requires accurate assessment. There is no consensus on the best methodology for capturing the phenomenon, thus leading to inconsistent results in this area. Objective: We aim to evaluate the reliability of clinicians' ratings and a discrepancy assessment method, examining groups of people with Alzheimer's disease (PwAD) according to their degree of awareness and demographic and clinical aspects. Methods: We cross-sectionally assessed 134 PwAD and their caregivers. Individuals' level of awareness was assessed with two methods: clinicians' ratings identified three groups (preserved awareness, impaired awareness, and absent awareness), while discrepancy assessment identified four groups (preserved awareness, mildly impaired awareness, moderately impaired awareness, and absent awareness). Results: Clinicians' ratings showed significant differences between PwAD with preserved, impaired, and absent awareness groups in cognition, functionality, and neuropsychiatric symptoms. There was a significant difference in caregivers' anxiety between the impaired and absent awareness groups. Discrepancy assessment showed no clinical differences between the preserved and mildly impaired awareness groups or between the absent and moderately impaired awareness groups. A significant difference in functionality was observed between the other groups. Conclusions: Clinical aspects of each measure tended to differ between the chosen methods. Impairments in awareness fluctuate despite disease progression. Cognition and severity of disease cannot explain deficits in awareness.

Affective theory of mind in people with mild and moderate Alzheimer's disease.

OBJECTIVE: This study compared the affective theory of mind (ToM) of people with mild and moderate Alzheimer's disease (AD) and healthy older adults and also investigated the relationship between affective ToM and cognitive and clinical functioning in AD people. METHODS: This cross-sectional study included 156 older adults with AD and 40 healthy older adults. We used an experimental task involving reasoning processes in different contextual situations. RESULTS: The affective ToM was impaired in AD groups compared with healthy group, with moderate AD group showing lower performance than mild AD group. The affective ToM task of mild AD group was significantly correlated with the Mini-Mental State Examination (MMSE) and education years. Linear regression showed only education years as a predictor of ToM task performance. The neuropsychiatric symptoms and functionality were not correlated with the affective ToM. CONCLUSIONS: Our findings demonstrated that people with mild and moderate AD presented impairments in affective ToM that can be explained by the difficulties to infer emotion from reasoning processes. In addition, the education years variable proved to be an affective ToM performance's predictor for the mild AD group, but not for the moderate AD group, indicating that ToM abilities are affected differently in different stages of AD. Neuropsychiatric symptoms and functionality seem to have no influence on affective ToM impairments in people with AD.

The relationship between burden and caregiver's sleep disturbances in dementia: a systematic review.

Caregivers of people living with dementia (PLwD) have a high burden degree that leads to health issues, including sleep. Objective: This study aimed to analyze the impacts of the caregiving burden on caregiver's sleep disturbances. Methods: This systematic review involved a qualitative analysis of publications on Web of Science and Pubmed/Medline databases published between February 2018 and August 2022. Results: A total of 27 studies were identified and analyzed. Caregiver's sleep presents impairments in sleep latency, sleep fragmentation, sleep duration, subjective sleep quality, daytime dysfunction, and insomnia. Caregiver's distress and depressive symptoms have a dual relationship with sleep problems. Conclusion: Sleep disturbances presented by caregivers are correlated with higher burden levels and lead to more vulnerability to psychiatric symptoms and health issues.

Métodos: Esta revisão sistemática envolveu a análise de resultados quantitativos e qualitativos de publicações das bases de dados Web of Science e PubMed/ Medical Literature Analysis and Retrieval System Online (Medline) publicadas entre fevereiro de 2018 e agosto de 2022. Resultados: O total de 27 estudos foi identificado e analisado. Cuidadores apresentam prejuízos na latência, fragmentação, duração e qualidade subjetiva do sono, disfunção diurna e insônia. O estresse e sintomas depressivos apresentados pelo cuidador possuem com o sono uma relação bidirecional. Conclusão: Os distúrbios do sono apresentados pelos cuidadores estão correlacionados com o alto nível de sobrecarga e geram maior vulnerabilidade para sintomas psiquiátricos e problemas de saúde.

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.

Home care for the elderly with dementia: a systematic review.

Objetive: With the global population aging, there is a growing need for home-based care to meet the health needs of the elderly. However, the quality of care provided to the aged population is now arguably a significant challenge for most healthcare systems worldwide. Methods: The present review included 13 original studies on home care and its effects on dementia patients, describing how patient care and adequate treatment can be collaborative for their improvement, for case management, and optimizing pain control and specificities. Results: Among the findings, it was evidenced that the environment impacts the form of care, once being at home can improve communication and global monitoring of dementia patients. Conclusion: In addition to the results analyzed in this review, there is a need for future, well-designed studies on the different aspects of home care, highlighting the importance of evaluating the type of care for each patient in the quest to optimize the care.

Objetivo: Com o envelhecimento da população mundial, há uma necessidade crescente de cuidados domiciliares para atender às necessidades de saúde dos idosos. No entanto, a qualidade dos cuidados prestados à população idosa é hoje indiscutivelmente um grande desafio para a maioria dos sistemas de saúde em todo o mundo. Métodos: A presente revisão incluiu 13 estudos originais sobre cuidados domiciliares e seus efeitos em pacientes com demência, descrevendo como o cuidado e o tratamento adequado do paciente podem ser colaborativos para sua melhora, para o gerenciamento de casos e a otimização do controle de sua dor e especificidades. Resultados: Entre os achados, evidenciou-se que o ambiente impacta a forma de atendimento, pois estar em casa pode melhorar a comunicação e o acompanhamento global dos pacientes em quadro demencial. Conclusão: Além dos resultados analisados nesta revisão, há a necessidade de futuros estudos bem elaborados sobre os diferentes aspectos da atenção domiciliar, destacando a importância de avaliar o tipo de cuidado de cada paciente na busca de otimizar o cuidado.

"Sexual activity for me is something else. It's the same as always: Sex aside and our love for each other." Changes in sexual activity in dementia from the view of spouse-carers'.

The study aimed to explore the impact of Alzheimer's disease (AD) on spouse-carer's lives and the ways it affects their marital relationship and sexual activity. Data were obtained from qualitative interviews conducted with 11 spouse-carers of people with AD. Using interpretative phenomenological analysis (IPA), three themes emerged: psychological and emotional impact, social impact, and sexual impact. Some spouse-carers reported stress, poor emotional well-being, frustration, doubts about how to deal with the situation, sadness, loneliness, perception of losing connection with the partner, and feelings of companionship disappearing. Meanwhile, other spouse-carers reported closer relations and greater affection for their care-recipients after the diagnosis. Changes in sexual activity were attributed to aging and/or the effects of the illness. Gender influenced the perception of changes in the marital relationship but not in sexual activity. Participants reported conflicting perspectives towards the importance of sexual activity in the marital relationship and the replacement of sexual intercourse with other modes of expressing affection. We believe that understanding the specificities of marital relationships of couples in whom one spouse was diagnosed with AD would be helpful for developing coping strategies for persons living with dementia and their spouses.

Awareness of Disease and Its Domains in Young-onset and Late-onset Dementia: The Role of Executive Function.

INTRODUCTION: Executive function (EF) involves a general cognitive process linked to strategic organization and control of complex goal-oriented tasks. In young-onset dementia (YOD), especially Alzheimer's disease, the symptoms that stand out in the initial stage are deficits in attention, visual-spatial function, praxis, and language. The present study aims to investigate what components of EF differ in young and late-onset dementia (LOD) and its impact on awareness and its domains. METHODS: Using a cross-sectional design, we included 44 people with YOD and 70 with LOD. We assessed awareness and its domains, cognition, dementia severity, EF, functionality, and neuropsychiatric symptoms. RESULTS: The YOD group was more impaired in general cognition ( P =0.017) and had a worse performance in Wechsler Digit Span Backward (DSB) ( P =0.007) and Phonemic fluency task (FAS) ( P =0.046) tests. In the LOD group, deficits in EF had a greater impact on awareness and on most domains (awareness total score, cognitive functioning and health condition, functional activity impairments and social function). CONCLUSIONS: Our study findings support the heterogeneity of awareness, not only with regard to the difference between the domains and the measures of EF, but also to the groups studied.

Modelling the impact of functionality, cognition, and mood state on awareness in people with Alzheimer's disease.

OBJECTIVES: To investigate the nature of the relationship between cognitive function, mood state, and functionality in predicting awareness in a non-clinically depressed sample of participants with mild to moderate Alzheimer's disease (AD) in Brazil. METHODS: People with AD (PwAD) aged 60 years or older were recruited from an outpatient unit at the Center of AD of the Federal University of Rio de Janeiro, Brazil. Measures of awareness of condition (Assessment Scale of the Psychosocial Impact of the Diagnosis of Dementia), cognitive function (Mini-Mental State Examination), mood state (Cornell Scale for Depression in Dementia), and functionality (Pfeffer Functional Activities Questionnaire) were applied to 264 people with mild to moderate AD and their caregivers. Hypotheses were tested statistically using SEM approach. Three competing models were compared. RESULTS: The first model, in which the influence of mood state and cognitive function on awareness was mediated by functionality, showed a very good fit to the data and a medium effect size. The competing models, in which the mediating variables were mood state and cognitive function, respectively, only showed poor model fit. CONCLUSION: Our model supports the notion that the relationship between different factors and awareness in AD is mediated by functionality and not by depressive mood state or cognitive level. The proposed direct and indirect effects on awareness are discussed, as well as the missing direct influence of mood state on awareness. The understanding of awareness in dementia is crucial and our model gives one possible explanation of its underlying structure in AD.

'I do not enjoy too much being with people, it takes me a long time to interact': a qualitative analysis of awareness of relationships in people with dementia.

OBJECTIVES: To investigate the presence of awareness of changes in relationships domain, and additional subdomains (cognitive, emotional and functional status) in a group of participants with dementia. METHOD: Using a qualitative design, 9 participants with mild and moderate dementia attended in a day care center were interviewed. Analyses were implemented throughout the modified version of the Grounded Theory Method. RESULTS: Some participants well-recognized changes in their relationships, albeit a tendency to immediately deny those changes was observed among them. The participants' reports showed that the kind of familiar or social relationship might facilitate the expression of awareness. Less discomfort in social interactions with familiars and friends compared to embarrassment with unfamiliar relationships were described. All participants could partially recognize their cognitive deficits, although attempts to normalize their condition and minimize difficulties were identified. Only two participants partially recognized changes in all investigated domains. The other participants partially described changes in two domains beyond the cognitive domain, such as relationships and emotional status or emotional and functional status. However, answers concerning emotional status reflected that some coping styles were not related to a general condition. CONCLUSION: The relationship domain may provide a valuable perspective of awareness of disease. People with dementia may feel less embarrassed to recognize deficits in the presence of familiars and friends.

Online physical exercise and the neuropsychiatric symptoms in patients with dementia: a cross-sectional study during the COVID-19 pandemic / Exercício físico online e sintomas neuropsiquiátricos em pacientes com demência: um estudo de corte transversal durante a pandemia de covid-19

ABSTRACT. Social isolation is necessary during the COVID-19 pandemic but can be harmful to mental health, especially in people with neurocognitive disorders. Although physical exercise can alleviate neuropsychiatric symptoms and improve quality of life (QoL), sedentary behavior increased during the pandemic. Online interventions can contribute to improving physical activity and mental health. Objective: The objective of this study was to compare the neuropsychiatric symptoms and QoL of older adults with neurocognitive disorders who participated in an online physical exercise program with sedentary patients during the COVID-19 pandemic. Methods: In this cross-sectional study, 25 older patients with neurocognitive disorders (control group=11; online exercise group=14) were evaluated based on Neuropsychiatric Inventory (NPI) and the Quality of Life in Alzheimer's Disease (QoL-AD) scale. Results: There were differences between the two groups in the total NPI (U=36.50, p=0.025) and the nighttime behavior disturbances item (U=38.00, p=0.033), both with large effect sizes (ES=-1.03, 95% confidence interval [CI]:-1.83 to -0.16 and ES=-1.06, 95%CI -1.86 to -0.19, respectively). In terms of QoL-AD, a difference was identified only in the memory subitem (U=20.00, p=0.005), with a large ES (1.59, 95%CI 0.59-2.48). Conclusions: Older adults with neurocognitive disorders who participated in an online physical exercise program, during the COVID-19 pandemic, showed fewer neuropsychiatric total symptoms, fewer nighttime disturbances episodes, and better subjective memory, compared to their physically inactive counterparts. Randomized controlled trials should be performed to better understand the effect of physical exercise in neuropsychiatric symptoms in dementia patients during periods of social isolation.

RESUMO. O isolamento social é necessário na pandemia de COVID-19, mas pode impactar a saúde mental, especialmente em idosos com demência, dada a alta prevalência de sintomas neuropsiquiátricos. Apesar da prática de exercícios físicos contribuir para a redução desses sintomas e a melhora da qualidade de vida, houve um aumento de comportamento sedentário durante a pandemia. Objetivo: Comparar os sintomas neuropsiquiátricos e a qualidade de vida de idosos com distúrbios neurocognitivos que participaram de um programa de exercícios físicos online voltado a pacientes sedentários durante a pandemia de COVID-19. Métodos: Neste estudo de corte transversal, 25 idosos diagnosticados com transtorno neurocognitivo (controle=11; exercícios online=14) foram avaliados por meio do inventário neuropsiquiátrico (INP) e da escala de qualidade de vida na doença de Alzheimer (QV-DA). Resultados: Observou-se diferença entre os grupos no INP total (U=36,50, p=0,025), com tamanho de efeito grande (effect size [ES]=-1,03, intervalo de confiança - IC95% -1,83 a -0,16), e no subdomínio sono (U=38,00, p=0,033), com tamanho de efeito grande (ES=-1,06, IC95% -1,86 a -0,19), favoráveis ao grupo fisicamente ativo. Na QV-DA, houve diferença entre os grupos apenas no subitem memória (U=20,00, p=0,005), com tamanho de efeito grande (ES=1,59, IC95% 0,59 a 2,48), não houve diferença na pontuação total (U=45,5, p=0,277). Conclusões: Idosos submetidos a rotina de exercícios físicos com supervisão online na pandemia de COVID-19 apresentam menos sintomas neuropsiquiátricos, melhor qualidade de sono e memória quando comparados aos fisicamente inativos. Estudos randomizados controlados devem ser feitos para a melhor compreensão dos efeitos do exercício físico nos sintomas neuropsiquiátricos de pacientes com demência durante períodos de isolamento social.

Differences in the predictors of the resilience between carers of people with young- and late-onset dementia: a comparative study / Diferenças nos preditores da resiliência entre cuidadores de pessoas com demência de início precoce e tardio: um estudo comparativo

ABSTRACT Resilience is a subjective process related to both protective and risk factors, external and internal to the individual. Considering the psychosocial differences between young-onset dementia (YOD) and late-onset dementia (LOD) groups, carers' resilience may not be understood in the same way in both groups. Objective: The aim of this study was to compare the resilience of carers in YOD and LOD and to examine which factors might be associated with resilience in both groups of carers. Methods: The study was conducted with 120 people with dementia (49 YOD) and their primary carers. The carers had their resilience, quality of life, depressive symptoms, and burden assessed and answered the sociodemographic questionnaire. We assessed care recipients' global cognition, dementia severity, social cognition, facial expression recognition, awareness of disease, the ability to perform activities of daily living, depressive symptoms, and neuropsychiatric symptoms. For data analysis, unpaired two-tailed Student's t-test and linear regressions were conducted. Results: Resilience did not differ between groups (p=0.865). Resilience was inversely related to carers' depressive symptoms in both YOD (p=0.028) and LOD (p=0.005) groups. The carers' schooling (p=0.005), duration of disease (p=0.019), and depressive symptoms of care recipient (p<0.001) were related to carers' resilience only in LOD group. Conclusions: The context of care, clinical status of the care recipient, and mental health resources affected the carers' resilience in the LOD group. Conversely, resilience seems to be affected only by carers' mental health in the YOD group. The understanding of these differences is crucial for the developing of intervention strategies.

RESUMO A resiliência é um processo subjetivo relacionado a fatores de proteção e risco, externos e internos ao indivíduo. Considerando as diferenças psicossociais entre demência de início precoce (DIP) e demência de início tardio (DIT), a resiliência dos cuidadores pode não ser entendida da mesma maneira em ambos os grupos. Objetivo: O objetivo deste estudo é comparar a resiliência de cuidadores de DIP e DIT e examinar quais fatores poderiam estar associados à resiliência em ambos os grupos de cuidadores. Métodos: O estudo foi realizado com 120 pacientes com demência (49 DIP) e seus cuidadores primários. Os cuidadores tiveram sua resiliência, qualidade de vida, sintomas depressivos e sobrecarga avaliados e responderam ao questionário sociodemográfico. Avaliou-se a cognição global, a severidade da demência, a cognição social, o reconhecimento da expressão facial, a consciência da doença, a funcionalidade em atividades de vida diária, e os sintomas depressivos e neuropsiquiátricos dos pacientes. Para a análise dos dados, foram realizados teste t de Student bicaudal não pareado e regressões lineares. Resultados: Não houve diferença na resiliência entre os grupos (p=0,865). A resiliência foi inversamente relacionada com sintomas depressivos dos cuidadores em DIP (p=0,028) e DIT (p=0,005). A escolaridade do cuidador (p=0,005), tempo de doença (p=0,019) e sintomas depressivos dos pacientes (p<0,001) foram relacionados à resiliência apenas no grupo DIT. Conclusões: O contexto do cuidado, o estado clínico do paciente e os recursos de saúde mental afetaram a resiliência do cuidador no grupo DIT. Em contrapartida, a resiliência parece ser afetada apenas pela saúde mental do cuidador em DIP. O entendimento dessas diferenças é crucial para o desenvolvimento de estratégias de intervenção.

Depression and anxiety among online learning students during the COVID-19 pandemic: a cross-sectional survey in Rio de Janeiro, Brazil.

BACKGROUND: The COVID-19 pandemic introduced a global need to explore the potential and challenges of online education. OBJECTIVE: To evaluate the presence of depression and anxiety in university students and their level of satisfaction with online learning during the period of social isolation caused by the COVID-19 pandemic. METHOD: A cross-sectional design was used to evaluate 152 online learning students from six different university courses: Medicine, Psychology, Law, Engineering, Physiotherapy, and Business. The evaluation of the participants was carried out through an online survey in Rio de Janeiro, Brazil. Also, the Hospital Anxiety and Depression Scale was used to assess participants mental health. RESULTS: Most of the participants reported emotional impact, followed by learning impact, financial impact, social impact, and technological impact, with a significant difference in the presence of depressive symptoms, but no significant difference in anxiety. The participants presented moderate anxiety levels, with no significant differences between genders, and mild levels of depressive symptoms with significant differences between genders. Also, younger students were more anxious than older students. In addition, female students with less social contact presented more depressive symtoms. CONCLUSION: From a clinical perspective, the findings provide insights into mental health among university students during the COVID-19 pandemic. These findings may help in the development of effective screening strategies and in the formulation of interventions that improve the mental health of students.

Dementia and Mental Health During the COVID-19 Pandemic: A Systematic Review.

Objectives: The COVID-19 pandemic raised significant concerns related to the management of care for people with dementia, but few studies have examined the mental health of older adults with dementia and their caregivers during the pandemic, when compared to other populations. This systematic review thus aims to compare and discuss the impact of the COVID-19 pandemic on people with dementia and on their caregivers' mental health. Methods: A search was performed in the PubMed/Medline and ISI databases according to the PRISMA methodology. We included studies published in 2020 and 2021 with the following combinations of keywords: "COVID-19 and mental health and elderly," "COVID-19 and mental health and dementia;" "COVID-19 and dementia and caregivers," "pandemic and mental health and elderly," and "pandemic and anxiety." Results: Twenty-two studies were included. Technology has proven to be an essential ally during the pandemic, since all 22 studies performed remote data collection. Nearly all the studies emphasized that social isolation and withdrawal can lead to the emergence or increase of neuropsychiatric symptoms and motor difficulties. However, the findings were mixed concerning the pandemic's impact on the cognition of people with dementia. Caregivers also suffered from the pandemic's impact, experiencing an increase in the burden of care and symptoms of stress, depression, and anxiety. Few studies suggested measures to alleviate the difficulties of people with dementia and their caregivers. There are reports of the benefits of technology in communication and treatment through teleconsultations, however, not everyone has access to such technology, making it difficult to disseminate this tool to the target population. Conclusions: The studies generally showed that social isolation can increase motor deficits and neuropsychiatric symptoms and caregivers' burden and anxiety. New avenues for care and intervention are thus needed for older adults with cognitive deficits and their caregivers to avoid the intensification of physical and psychological suffering. Technological initiatives and support should consider people with cognitive impairment and different levels of technology literacy.

Active music therapy in dementia: results from an open-label trial / Musicoterapia ativa na demência: resultados de um estudo aberto

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.
