ABSTRACT

ABSTRACT The recognition of Cerebrovascular Disease (CVD) at earlier clinical stages may favor the control of vascular risk factors and prevention of dementia. However, operational criteria for symptomatic phases at non-dementia stages are often difficult, as the current criteria normally require the evidence of extensive subcortical disease. OBJECTIVE To identify the neuroimaging profile of Vascular Mild Cognitive Impairment (VaMCI), the impact of those aspects over cognition and the neuropsychological tests that distinguished VaMCI from other groups. METHODS Searches were performed in Scopus, ISI and PsycINFO, using the following key terms: "vascular mild cognitive impairment" OR "vascular cognitive impairment no dementia" OR "vascular cognitive impairment not demented" OR "subcortical mild cognitive impairment". RESULTS Of 249 papers, 20 studies were selected. Ten of those included only patients with severe White Matter Hyperintensities (WMH), whereas 10 others admitted subjects with moderate-to-severe WMH. Both groups showed poor performances in Executive Function (EF) tasks in comparison to normal controls and other diagnostic groups. Among EF tests, those assessing "complex" EF abilities consistently distinguished VaMCI from other groups, regardless of the severity of WMH. VaMCI subjects with severe or moderate-to-severe WMH showed cognitive deficits in comparison with other groups. "Complex" EF tests were the most useful in differentiating those patients from the other groups. CONCLUSION The occurrence of VaMCI may be associated with the presence of CVD at moderate levels; the detection of vascular damage at earlier stages may allow the adoption of therapeutic actions with significant effect-sizes.


RESUMO O reconhecimento precoce da Doença Cerebrovascular (DCV) pode permitir o controle de fatores de risco e a prevenção de demência. Contudo, critérios operacionais em seus estágios sintomáticos não-demenciais apresentam problemas, já que critérios atuais requerem a presença de extensa doença isquêmica subcortical. OBJETIVO Identificar o perfil de neuroimagem do Comprometimento Cognitivo Leve Vascular (CCLV), o impacto destes aspectos sobre a cognição e os testes neuropsicológicos que distinguem CCLV de outros grupos. MÉTODOS Foram realizadas buscas no Scopus, ISI e PsycINFO, usando a estratégia: "vascular mild cognitive impairment" OR "vascular cognitive impairment no dementia" OR "vascular cognitive impairment not demented" OR "subcortical mild cognitive impairment". RESULTADOS De 249 artigos, 20 foram selecionados. 10 destes incluíram apenas pacientes com hiperintensidades de substância branca (HSB) graves, enquanto 10 outros admitiram pacientes com HSB moderadas-a-graves. Ambos os grupos apresentaram desempenho pobre em tarefas de Função Executiva (FE) em comparação com controles normais e outras categorias diagnósticas. Dentre os testes de FE, aqueles que avaliam FE "complexas" diferiram consistentemente CCLV de outros grupos, independentemente da gravidade de HSB. Sujeitos com CCLV e HSB graves ou moderadas-a-graves apresentaram dificuldades cognitivas quando comparados aos demais grupos. Testes que avaliam FE "complexa" foram os mais úteis na diferenciação destes pacientes dos outros grupos. CONCLUSÃO A ocorrência de VaMCI pode estar associada à presença de HSB moderadas; a detecção precoce do dano vascular permitiria a adoção de medidas terapêuticas com tamanhos de efeito significativos.

ABSTRACT

Neuropsychiatric symptoms or Behavioral and Psychological Symptoms of Dementia (BPSD) are common and invariably appear at some point during the course of the disease, mediated both by cerebrovascular disease and neurodegenerative processes. Few studies have compared the profiles of BPSD in Vascular Cognitive Impairment (VCI) of different subtypes (subcortical or cortical) and clinical stages (Vascular Cognitive Impairment No Dementia [VaCIND] and Vascular Dementia [VaD]).Objective:To review the BPSD associated with different subtypes and stages of VCI using the Neuropsychiatric Inventory (NPI).Methods:Medline, Scielo and Lilacs databases were searched for the period January 2000 to December 2014, with the key words: "BPSD AND Vascular Dementia, "NPI AND Vascular Dementia" and "NPI AND VCI. Qualitative analysis was performed on studies evaluating BPSD in VCI, using the Neuropsychiatric Inventory (NPI).Results:A total of 82 studies were retrieved of which 13 were eligible and thus included. Among the articles selected, 4 compared BPSD in Subcortical Vascular Dementia (SVaD) versus Cortical-Subcortical Vascular Dementia (CSVaD), 3 involved comparisons between SVaD and VaCIND, 1 study analyzed differences between CSVaD and VaCIND, while 5 studies assessed BPSD in CSVaD. Subcortical and Cortical-Subcortical VaD were associated predominantly with Apathy and Depression. VaCIND may present fewer behavioral symptoms than VaD.Conclusion:The profile of BPSD differs for different stages of VCI. Determining the most prevalent BPSD in VCI subtypes might be helpful for improving early diagnosis and management of these symptoms.

Tanto a DVCS quanto a DVS associaram-se principalmente a Apatia e Depressão. O CCVND pode apresentar menos sintomas comportamentais que a DV.Conclusão:O perfil dos SCPD difere entre diferentes estágios do CCV. O entendimento dos SCPD mais prevalentes nos subtipos do CCV poderia ser útil para facilitar o diagnóstico precoce e o manejo desses sintomas.

ABSTRACT

In order to assess ecological validity of executive function (EF) tests and the impact of EF dysfunction on functional status in elderly subjects with moderate and severe subcortical white matter hyperintensities (WMHs), we made a correlation analysis between EF scores and two measures of Instrumental Activities of Daily Living (IADL). Trail-making test and CLOX correlated with the ability to perform IADL in subjects with severe WMH. EF tests might present low ecological validity for those with WMH below severe stage.

ABSTRACT

Neuropsychiatric symptoms (NPS) of dementia constitute one of the most related factors to caregiver burden and patients' early institutionalization. Few studies in Brazil have examined which symptoms are associated with higher levels of caregiver distress. OBJECTIVE: To evaluate the caregiver distress related to individual NPS in familial caregivers of patients with dementia. We also examined which caregiver and patient factors predict caregiver distress associated with NPS. METHODS: One hundred and fifty-nine familial caregiver and dementia outpatient dyads were included. The majority of the patients had a diagnosis of Alzheimer's disease (66.7%). Caregivers were assessed with a sociodemographic questionnaire, Beck Anxiety and Depression Inventories, and the Neuropsychiatric Inventory - Distress Scale. Patients were submitted to the Mini-Mental State Examination, Functional Activities Questionnaire, and the Neuropsychiatric Inventory. Spearman's rank correlation was used to assess the relationships between the continuous variables. Multiple linear regression analyses with backward stepping were performed to assess the ability of caregiver and patient characteristics to predict levels of caregiver distress associated with NPS. RESULTS: Apathy (M=1.9; SD=1.8), agitation (M=1.3; SD=1.8), and aberrant motor behavior (AMB) (M=1.2; SD=1.7) were the most distressful NPS. The frequency/severity of NPS was the strongest factor associated with caregiver distress (rho=0.72; p<0.05). CONCLUSION: The early recognition and management of apathy, agitation and AMB in dementia patients by family members and health professionals may lead to better care and quality of life for both patients and caregivers.


Os sintomas neuropsiquiátricos (SNP) da demência constituem um dos fatores mais relacionados à sobrecarga do cuidador e à institucionalização precoce do paciente. Poucos estudos brasileiros examinaram quais sintomas estão associados ao desgaste do cuidador. OBJETIVO: Avaliar o desgaste referente aos SNP individuais cuidadores familiares dos pacientes com demência. Nós também analisamos quais fatores dos pacientes e dos cuidadores constituem fortes preditores ao desgaste do cuidador. MÉTODOS: Cento e cinquenta cuidadores familiares e pacientes foram incluídos. A maioria dos pacientes possuía um diagnóstico de doença de Alzheimer (66,7%). Os cuidadores foram avaliados através de um questionário sociodemográfico, os Inventários de Ansiedade e Depressão de Beck e o Inventário Neuropsiquiátrico - Desgaste. Os pacientes foram submetidos ao Mini-Exame do Estado Mental, Escala de Atividades Funcionais e ao Inventário Neuropsiquiátrico. A correlação de Spearman foi utilizada para avaliar as relações entre as variáveis contínuas. Análises regressivas lineares múltiplas foram realizadas para analisar, dentre as variáveis dos pacientes e dos cuidadores, os fatores preditores do desgaste do cuidador. RESULTADOS: Apatia (M=1,9; DP=1,8), agitação (M=1,3; DP=1,8) e comportamento aberrante motor (CMA) (M=1,2; DP=1,7) foram os SNP mais desgastantes. A frequência/gravidade dos SNP foi o fator mais fortemente associado ao desgaste do cuidador (rho=0.72; p<0,05). CONCLUSÃO: O reconhecimento precoce e manejo da apatia, agitação e CMA nos pacientes com demência pelos familiares e profissionais de saúde possivelmente levará a uma melhor qualidade vida e cuidado para pacientes e cuidadores.

ABSTRACT

UNLABELLED: Vascular mild cognitive impairment (VaMCI) represents an early symptomatic stage of vascular cognitive impairment and might be associated to fronto-executive dysfunction. METHODS: Twenty-six individuals (age: 73.11±7.90 years; 65.4% female; schooling: 9.84±3.61 years) were selected through neuropsychological assessment and neuroimaging. Clinical and neuroimaging data of VaMCI individuals (n=15) were compared to normal controls (NC, n=11) and correlated with Fazekas scale. RESULTS: VaMCI performed significantly worse than NC in Trail-Making Test (TMT) B, errors in TMT B, difference TMT B-A and Cambridge Cognitive Examination (CAMCOG) final scores. Correlations were found among scores in modified Fazekas scale and performances in TMT B (time to complete and errors), difference TMT B-A and CAMCOG total score. CONCLUSION: Extension of white matter hyperintensities might be correlated to poorer global cognition and impairments in a set of fronto-executive functions, such as cognitive speed, set shifting and inhibitory control in VaMCI.

Comprometimento cognitivo leve vascular (CCLV) representa um estágio sintomático precoce do comprometimento cognitivo vascular e associa-se à disfunção fronto-executiva. Métodos Vinte e seis indivíduos (idade: 73,11±7,90 anos; 65,4% mulheres; escolaridade: 9,84±3,61 anos) foram selecionados por meio de avaliação cognitiva e neuroimagem. Os dados clínicos e de neuroimagem do grupo CCLV (n=15) foram comparados com controles normais (CN; n=11) e correlacionados com a escala de Fazekas. Resultados CCLV apresentaram piores desempenhos que CN no Trail-Making Test (TMT) B, erros no TMT B, diferença TMT B-A e pontuação final do Cambridge Cognitive Examination (CAMCOG). Verificaram-se correlações entre escala de Fazekas e desempenhos no TMT B (tempo total e erros), diferença TMT B-A e a pontuação final do CAMCOG. Conclusão A extensão das hiper-intensidades de substância branca, no grupo CCLV, correlacionou-se com pior desempenho cognitivo global e com comprometimento em um grupo de funções fronto-executivas, como velocidade e alternância cognitiva e controle inibitório. .

ABSTRACT

Introdução: O continuum do comprometimento cognitivo vascular (CCV) compreende segmento não demência (CCV-ND), segmento demência (CCV-D ou DV), sendo o subtipo mais frequente o CCV subcortical, e inclui, ainda, formas mistas (CCV + DA). Ressonância magnética (RM) do cérebro é o método mais apropriado para avaliação das lesões vasculares, dimensão dos hipocampos e do espectro de prótons (1HMRS). Objetivo: Comparar os valores de metabólitos dos hipocampos (HC) e da região do cíngulo posterior (CP) em grupos de casos de CCV subcortical. Métodos: Casos (n = 55) foram selecionados a partir do banco de dados sobre CCV. Imagens obtidas por equipamento Signa Horizon LX-GE de 1,5T, com protocolo-padrão para aquisição estrutural (incluindo FLAIR, T2 e aquisição para 1H-MRS). Metabólitos estudados (relações) incluíram: Naa/Cr, Co/Cr e mI/Cr. Os casos foram definidos radiologicamente (leucoaraiose grau 3 pela escala de Fazekas modificada) e subdivididos de acordo com a escala de Leon (0-3) em dois em grupos hipocampais (grHC): grHC [0+1] e grHC [2+3]. Análise estatística pelo ANOVA e Tukey. Resultados: A relação Naa/Cr nos HC mostrou diferença significativa entre o grHC [0+1] e o grHC [2+3], o que representa diminuição de integridade (perda) neuronal no segundo, enquanto os CP desses grupos mantiveram os valores estáveis. Houve diferença significativa entre o grHC [2+3] em relação aos CP de ambos os grupos, enquanto o grHC [0+1] ficou compatível com os valores dos CP. Comparação dos valores obtidos em estudos anteriores em CCL e DA mostrou o Naa/Cr com valor intermediário entre os do CCL e da DA nos HC e equivalência de valores nos CP. Conclusão: A 1HMRS possibilita analisar o grau de perda neuronal, além de alterações de membrana e neuroglial dessas regiões. Assim, podem ser obtidas informações para melhor compreender o continuum CCV subcortical (que pode incluir CCV + DA), visando determinar a contribuição dessas duas patologias, caso haja, ao comprometimento cognitivo...


Introduction: Vascular cognitive impairment (VCI) continuum comprisesno-dementia segment (VCI-ND), dementia segment (VCI-D or VaD), with subcortical VCI as the most frequent subtype, and additionally mixed forms (VCI + AD). Magnetic resonance imaging (MRI) of the brain is the most proper method for vascular lesions, hippocampal size, and proton spectrum (1HMRS) assessment. Objective: Comparison of the values of metabolites at the hippocampi (HC) and posterior cingulate (PC) region of groups of cases of subcortical VCI. Methods: Cases (n = 55) were selected from a database on VCI. Images were obtained with Signa Horizon LX-GE de 1.5T equipment and a standard protocol for structural and 1H-MRS acquisitions. Studied metabolites (reasons) were: Naa/Cr, Coh/Cr e mI/Cr. The cases were radiologically defined (grade 3 leucoaraiosis on modified Fazekas scale), and according de Leon?s scale (0-3) subdivided in two hippocampal groups (grHC): grHC[0+1] and grHC[2+3]. Statistical analysis with ANOVA and Tukey. Results: The reason Naa/Cr at the HC showed a significant difference between the grHC[0+1] and grHC[2+3], that represents a reduction of neuronal integrity (loss) in the latter, while at PC these groups maintained stable values. There was a significant difference between grHC [2+3] in relation to PC of both groups, while grHC [0+1] remained compatible with PC values. The comparison of the values obtained from previous studies on MCI and AD showed Naa/Cr with intermediate values between MCI and AD at the HC, and equivalence at the PC. Conclusion: 1HMRS allows for the analysis of the degree of neuronal loss, besides membrane and neuroglial changes of these regions. Thus, information may be obtained for a better understanding of the subcortical VCI continuum (that may include VCI + AD), aiming to determine the contribution of these two pathologies, if present, to the cognitive impairment...

ABSTRACT

A tarefa de cuidar de um familiar com demência é reconhecida como associada ao estresse crônico, e a problemas físicos e emocionais no cuidador. Entretanto, a influência do tipo de demência sobre a autopercepção de saúde em cuidadores familiares ainda é pouco conhecida. Objetivos: Descrever características sociodemográficas e clínicas de uma amostra ambulatorial do Rio de Janeiro composta por pacientes com demência e seus cuidadores familiares, e examinar a relação entre o tipo de demência do paciente (VD: Demência Vascular; DA: Doença de Alzheimer; DM: Demência Mista) e a autopercepção de saúde em cuidadores familiares. Métodos: A amostra (n=49) foi constituída por pacientes com demência e seus cuidadores familiares atendidos regularmente em um ambulatório de Psicogeriatria no Rio de Janeiro. Pacientes foram avaliados com Mini-Exame do Estado Mental, Questionário de Atividades Funcionais, Inventário Neuropsiquiátrico e Escala de Estadiamento da Demência. Cuidadores foram investigados com um Questionário Sociodemográfico e Clínico, que inclui questões de autopercepção de saúde física e emocional, além dos Inventários Beck de Depressão e Ansiedade, e Entrevista de Sobrecarga Zarit. Resultados: Cuidadores familiares de pacientes com DA apresentaram pior autopercepção de saúde física quando comparados aos familiares provedores de cuidados dos grupos dos outros tipos de demência, apesar da diferença não ter alcançado nível de significância estatística. A queixa de dor foi o problema físico mais frequente nos cuidadores nos três tipos diagnósticos...


Provide care for a demented relative is recognized as associated to chronic strain, and also to caregiver's physical and emotional problems. However, little is known about the influence of the dementia type on family caregiver health self-perception. Objectives: Describe sociodemographic and clinical factors of an outpatients sample in Rio de Janeiro composed by demented patients and their family caregivers, and to investigate the relation of the dementia type (Vascular Dementia: VaD; Alzheimer Disease: AD; Mixed Dementia: MD) with family caregivers health self-perception. Methods: Outpatients (n=49) with dementia were evaluated with Mini-Mental State Examination, Functional Activities Questionnaire, Neuropsychiatric Inventory, and Clinical Dementia Rating. Caregivers were assessed with a Sociodemographic and Clinical Questionnaire, Beck Depression and Anxiety Inventories, and Zarit Burden Interview. Results: Family caregivers of AD patients presented poorer physical health self-perception when compared to family caregivers of the other dementia types, however these differences did not reach the statistical level. Physical and emotional complains were reported by the majority of caregivers of all dementia types. Complaint of pain was the most frequent physical problem among the three diagnostic types...

ABSTRACT

Introdução: O Exame Cognitivo Cambridge (CAMCOG) é um instrumento breve para avaliação cognitiva. É composto por subescalas que representam diversos domínios cognitivos (orientação, linguagem, memória, atenção, praxia, percepção, cálculo e pensamento abstrato). Escores totais adequados permitem definir comprometimento em nível de demência. Entretanto, tais escores totais nem sempre representam o desempenho real de um indivíduo, pois é possível obter escores baixos em determinado(s) domínio(s) e ainda manter um escore total dentro da variação normal. Objetivo: Obter valores do CAMCOG total e das subescalas de indivíduos idosos normais com diferentes níveis de escolaridade. O interesse crescente na definição de estágios pré-demência é uma razão importante do presente estudo. Métodos: Foram avaliados com CAMCOG idosos normais residindo na comunidade, divididos em três grupos de acordo com o nível de escolaridade. Foi realizada análise estatística para comparar a significância dos escores (total e subescalas) entre os grupos. Resultados: Os valores médios do CAMCOG total mostraram aumento com a escolaridade, o mesmo tendo sido observado em relação aos escores das subescalas. Conclusão: As subescalas do CAMCOG relacionados com os níveis de escolaridade são necessárias para identificar indivíduos que apresentam diminuição de valores em um ou mais domínios cognitivos, apesar de apresentar o escore total dentro da variação da normalidade, o que pode caracterizar um estado de comprometimento cognitivo pré-demência...


Introduction: The Cambridge Cognitive Examination (CAMCOG) is a brief tool for cognitive assessment. It is composed of subscales that represent various cognitivedomains (orientation, language, memory, attention, praxis, perception, calculation and abstract thinking). Appropriate total scores permit to define impairment in the dementia level. However, such total scores do not always represent the real performance of the subject as it is possible to obtain low scores in certain domain(s) yet maintaining a total score in the normal range. Objective: To obtain data of CAMCOG total and subscales scores of normal elderly subjects with different educational levels. The growing interest in defining pre-dementia stages is an important reason of the present study. Methods: Community living normal elderly, divided in three groups according to their education level were assessed with CAMCOG. Statistic analysis was performed to compare significance of the scores (total and subscales) among the groups. Results: Total CAMCOG mean values increased with education, and the same was observed in relation to the subscales scores. Conclusion: CAMCOG subscales related to education levels are necessary to identify subjects who present decreased values on one or more cognitive domain despite total scores within normal range, which may characterize a pre-dementia cognitive impairment state...

ABSTRACT

BACKGROUND: Neuropsychiatric symptoms (NPS) affect the majority of patients who have dementia. Neuropsychiatric sub-syndromes with symptoms that occur together and have common neurobiological correlates have been identified. There are scarce data regarding the comparison of the pattern of the neuropsychiatric sub-syndromes in distinct ethnical and cultural populations. We aim at comparing the pattern of the NPS, and the factor analysis of the Neuropsychiatric Inventory (NPI-10) in two samples of outpatients with dementia living in Brazil and Norway. METHODS: This is a cross-sectional study. The sample consists of 168 Brazilian and 155 Norwegian demented patients from psychogeriatric facilities and community-based educational programs. Brazilian patients were diagnosed with Alzheimer's disease (63.7%), vascular dementia (15.5%), or mixed dementia (20.8%), whereas the diagnoses of Norwegian patients were Alzheimer's disease (97.4%) and mixed dementia (2.6%). Principal component analysis with the Varimax rotation was used for factor analysis of the NPI-10. RESULTS: Apathy (80.4 %), agitation/aggression (45.8%), and aberrant motor behavior (45.8%) were the most common symptoms in the Brazilian sample. Apathy (72.3%), dysphoria (61.9%), and anxiety (52.3%) were the most frequent symptoms in the Norwegian sample. Factor analysis of the NPI-10 revealed three syndromes for the Brazilian (Psychosis, Mood, Psychomotor) and Norwegian (Psychosis, Mood, Frontal) groups. CONCLUSIONS: The frequency of individual NPS may differ among distinct populations. However, Psychosis and Depression are common sub-syndromes in diverse ethnical and cultural patients with dementia. Our findings support the syndromic approach for the clinical assessment of the patients with dementia.

ABSTRACT

Neuropsychiatric symptoms (NPS) of dementia constitute one of the most related factors to caregiver burden and patients' early institutionalization. Few studies in Brazil have examined which symptoms are associated with higher levels of caregiver distress. OBJECTIVE: To evaluate the caregiver distress related to individual NPS in familial caregivers of patients with dementia. We also examined which caregiver and patient factors predict caregiver distress associated with NPS. METHODS: One hundred and fifty-nine familial caregiver and dementia outpatient dyads were included. The majority of the patients had a diagnosis of Alzheimer's disease (66.7%). Caregivers were assessed with a sociodemographic questionnaire, Beck Anxiety and Depression Inventories, and the Neuropsychiatric Inventory - Distress Scale. Patients were submitted to the Mini-Mental State Examination, Functional Activities Questionnaire, and the Neuropsychiatric Inventory. Spearman's rank correlation was used to assess the relationships between the continuous variables. Multiple linear regression analyses with backward stepping were performed to assess the ability of caregiver and patient characteristics to predict levels of caregiver distress associated with NPS. RESULTS: Apathy (M=1.9; SD=1.8), agitation (M=1.3; SD=1.8), and aberrant motor behavior (AMB) (M=1.2; SD=1.7) were the most distressful NPS. The frequency/severity of NPS was the strongest factor associated with caregiver distress (rho=0.72; p<0.05). CONCLUSION: The early recognition and management of apathy, agitation and AMB in dementia patients by family members and health professionals may lead to better care and quality of life for both patients and caregivers.


Os sintomas neuropsiquiátricos (SNP) da demência constituem um dos fatores mais relacionados à sobrecarga do cuidador e à institucionalização precoce do paciente. Poucos estudos brasileiros examinaram quais sintomas estão associados ao desgaste do cuidador. OBJETIVO: Avaliar o desgaste referente aos SNP individuais cuidadores familiares dos pacientes com demência. Nós também analisamos quais fatores dos pacientes e dos cuidadores constituem fortes preditores ao desgaste do cuidador. MÉTODOS: Cento e cinquenta cuidadores familiares e pacientes foram incluídos. A maioria dos pacientes possuía um diagnóstico de doença de Alzheimer (66,7%). Os cuidadores foram avaliados através de um questionário sociodemográfico, os Inventários de Ansiedade e Depressão de Beck e o Inventário Neuropsiquiátrico ­ Desgaste. Os pacientes foram submetidos ao Mini-Exame do Estado Mental, Escala de Atividades Funcionais e ao Inventário Neuropsiquiátrico. A correlação de Spearman foi utilizada para avaliar as relações entre as variáveis contínuas. Análises regressivas lineares múltiplas foram realizadas para analisar, dentre as variáveis dos pacientes e dos cuidadores, os fatores preditores do desgaste do cuidador. RESULTADOS: Apatia (M=1,9; DP=1,8), agitação (M=1,3; DP=1,8) e comportamento aberrante motor (CMA) (M=1,2; DP=1,7) foram os SNP mais desgastantes. A frequência/gravidade dos SNP foi o fator mais fortemente associado ao desgaste do cuidador (rho=0.72; p<0,05). CONCLUSÃO: O reconhecimento precoce e manejo da apatia, agitação e CMA nos pacientes com demência pelos familiares e profissionais de saúde possivelmente levará a uma melhor qualidade vida e cuidado para pacientes e cuidadores.

ABSTRACT

OBJECTIVES: Familial caregivers of demented patients suffer from high levels of burden of care, but the literature is sparse regarding the prevalence and predictors of burnout in this group. Burnout is composed of three dimensions: emotional exhaustion (EE), depersonalization (DP) and reduced personal accomplishment (RPA). We aimed to investigate the associations between burnout dimensions and the caregivers' and patients' sociodemographic and clinical characteristics. METHODS: This study is cross-sectional in design. Caregivers (N = 145) answered the Maslach Burnout Inventory, Beck Depression Inventory, Beck Anxiety Inventory and a Sociodemographic Questionnaire. Patients (N = 145) were assessed with the Mini Mental State Examination, Functional Activities Questionnaire, Neuropsychiatric Inventory, and Clinical Dementia Rating Scale. RESULTS: High levels of EE were present in 42.1% of our sample, and DP was found in 22.8%. RPA was present in 38.6% of the caregivers. The caregivers' depression and the patients' delusions remained the significant predictors of EE. CONCLUSIONS: The presence of caregiver depression and patient delusions should always be part of the multidisciplinary evaluation of dementia cases.


OBJETIVOS: Os cuidadores familiares de pacientes com demência sofrem de altos níveis de sobrecarga de cuidados, mas a literatura referente a prevalência e os fatores preditores de burnout neste grupo é escassa. O burnout é composto por três dimensões: exaustão emocional (EE), despersonalização (DP) e reduzida realização pessoal (RRP). Nós temos como objetivo investigar as associações existentes entre as dimensões do burnout e as características clínicas e sóciodemográficas dos cuidadores e dos pacientes com demência. MÉTODOS: O estudo possui um delineamento transversal. Os cuidadores (N = 145) responderam ao Inventário de Burnout de Maslach, Inventário de Depressão de Beck, Inventário de Ansiedade de Beck, e um Questionário Sócio-Demográfico. Os pacientes (N = 145) foram avaliados através do Mini Exame do Estado Mental, Questionário de Atividades Funcionais, Inventário Neuropsiquiátrico e a Escala de Estadiamento Clínico das Demências. RESULTADOS: Altos níveis de EE foram encontrados em 42,1%, e de DP em 22,8% da amostra. RRP esteve presente em 38,6% dos cuidadores. A depressão dos cuidadores, e os delírios dos pacientes foram os principais fatores preditores de EE. CONCLUSÕES: A presença de depressão nos cuidadores, e de delírios nos pacientes devem sempre fazer parte da avaliação multidisciplinar da demência.

ABSTRACT

Strategic regions correspond to associative, limbic and paralimbic structures and related circuits, that underpin cognitive/behavioral functions. Strokes in these eloquent sites produce pictures of vascular dementia with syndromic features due to specific site lesion and/or interruption of their interconnections. This study aims at analysing subcortical strategic strokes that express similar cognitive/behavioral elements, by sharing common pathways. Patients (n=6) who attended in specialized ambulatory, were submitted to neuropsychological and neuroimaging assessments through MRI (GE Signa Horizon 1.5T) and brain SPECT (Millennium MG, ECD [TC-99m]). Stroke locations and respective main symptoms were: 1. anteromedian thalamus [L]: anterograde and retrograde amnesia (ARA), expression aphasia (EA), executive dysfunction (ED), apathy, and depression; 2. anterior thalamus [R]: ARA, inattention, apathy, and aggressiveness; 3. dorsomedian thalamus [L]: inattention, ED, anosognosia, and aggressiveness; 4. central paramedian thalamus [R]: EA, visual perception deficits (VPD), ED, infantility, and personality disorder; 5. caudate nucleus (ventral-head) [L]: VPD, ED, delirium, visual hallucinations, and personality disorder; and 6. anterior capsule [L]: VPD, ED, apathy, and depression. Vascular strategic syndromes connote the predominantly impaired cognitive/behavioral symptom of each site. Temporal and frontal disconnection symptoms were produced by disrupted MTT/hippocampal and IML/amygdala circuits expressing amnesic syndrome associated with heterogeneous dysexecutive syndrome, in all the cases, by disrupting frontal-basal ganglia-thalamus-cortical net, in three different levels of their pathway.

ABSTRACT

Non-amnestic dysexecutive Vascular Mild Cognitive Impairment (VaMCI) may represent preclinical Vascular Dementia (VaD). The aim of this study was to summarize the clinical, neuropsychological and neuroimaging aspects of VaMCI; and to assess its patterns of progression to dementia. Methods: Searches were made in the ISI Web of Knowledge, PubMed and Lilacs databases, using the terms mild cognitive impairment and executive function. Altogether, 944 articleswere retrieved. Results: VaMCI cases had poorer performances on fronto-executive tasks, a higher prevalence of stroke, presence of periventricular and profound white matter hyperintensities on MRI images, as well as more extrapyramidal signs and behavioral symptoms. Executive dysfunction might be associated with disconnection of fronto-parietal-subcortical circuits. Progression to dementia was associated with baseline deficits in executive function, in simple sustained attentionand language, and large periventricular WMH. Discussion. VaMCI develops with impairment in non-memory domains and subcortical white matter changes on MRI images, which are consistent with clinical and neuroimaging findings in VaD.


Comprometimento Cognitivo Leve Vascular (CCLV) não-amnésico disexecutivo pode representar a fase pré-clínica da Demência Vascular (DV). Este estudo tem por objetivo descrever os aspectos clínicos, cognitivos e de neuroimagem do CCLV, além de avaliar padrões de progressão para demência. Métodos: Foram realizadas buscas nas bases de dados ISI Web of Knowledge, PubMed e Lilacs, usando os termos comprometimento cognitivo leve e funçãoexecutiva. Ao todo, 944 artigos foram obtidos. Resultados: Pacientes com CCLV apresentaram piores desempenhos em tarefas fronto-executivas, histórico de acidentes vasculares encefálicos, presença de hiperintensidades da substância branca periventriculares e profundas, e mais, sinais extrapiramidais e sintomas comportamentais. A disfunção executiva parece se relacionar à desconexão de circuitos fronto-parieto-subcorticais. A progressão para demência relacionou-se a déficits em linguagem, função executiva e atenção sustentada à primeira avaliação, e a hiperintensidades na substância brancaperiventricular extensas. Discussão: O CCLV cursa com comprometimento cognitivo em domínios não-memória e alterações da substância branca subcortical à imagem por RM alinhadas com os achados característicos da DV.

ABSTRACT

Cerebrovascular disease (CVD) is often present in old age and may be associated with microstructural pathologyof white matter (WM) and cognitive dysfunction. The current review investigated the relationship between CVD, cognitive status and WM integrity as assessed by diffusion tensor imaging (DTI). Methods: DTI studies were searched on ISI and Pubmed databases from 2002 to 2012. Results: Studies evidenced DTI changes in WM as associated with vascular disease and provide increasing support for DTI as a valuable method for early detection of CVD. Conclusion: DTI parameters canserve as important biomarkers in monitoring vascular disease progression and treatment response and may represent asurrogate marker of WM tract integrity.


A doença cérebro-vascular (DCV) está frequentemente presente na idade avançada, podendo se associar à patologia microscópica da substância branca (SB) e à disfunção cognitiva. A presente revisão investiga a relação entre DCV, status cognitivo e a integridade da SB, através da avaliação pelo tensor de difusão (DTI). Métodos: Os estudos em DTI foram selecionados a partir das bases ISI e Pubmed entre 2002 a 2012. Resultados: Os estudos evidenciaram alterações do DTI na SB associadas à doença vascular e fornecem evidencia importante para o DTI como um método valioso para a detecção precoce da DCV. Conclusão: Os parâmetros do DTI podem servir como importantes biomarcadores na monitoração da doença vascular quanto a sua progressão e resposta terapêutica e parecem representar um marcador substituto da integridade da SB.

ABSTRACT

Neuropsychiatric symptoms are common in patients with cognitive impairments, mediated by both neurodegenerative processes and cerebrovascular disease. Previous studies have reported that Behavioral and Psychological Symptoms of Dementia (BPSD) might correlate with severity of cognitive decline. Thus far, the impact of the association between white-matter hyperintensities (WHM) and hippocampal atrophy (HA) on the incidence of these symptoms has beenless studied. Objective: This cross-sectional study aimed to describe the clinical profile of a sample with large extensions of WMH, examining the association between different degrees of HA and cognitive, functional, and behavioral status. Methods: Fifty outpatients (mean age: 76.86±8.70 years; 58% female; mean schooling: 7.44±4.69 years) with large extensionsof WMH (modified-Fazekas scale=3) on MRI and different degrees of hippocampal atrophy (according to de Leon Score)underwent cognitive, functional, and behavioral assessments. Results: Patients with mild-moderate to severe HA had worse performance on the Mini-Mental State Examination, Cambridge Cognitive Examination, Clinical Dementia Rating and Pfeffers Functional Activities Questionnaire, compared to the group with none or questionable HA. Appetite/Eating Behavior wasthe only cluster of neuropsychiatric symptoms associated with presence of HA in Vascular Cognitive Impairment patients. Discussion: Although HA may exhibit distinct impact on cognitive performance and functional status, it appears to havelittle effect on behavioral symptoms in patients with high severity WMH.


Sintomas neuropsiquiátricos são comuns em pacientes com déficits cognitivos associados aprocessos neurodegenerativos e à doença cerebrovascular. Estudos apontaram que os Sintomas Comportamentais ePsicológicos da Demência (SCPD) podem ter relação com a gravidade do declínio cognitivo. Até o presente, o impacto daassociação entre hiperintensidades da substância branca (HSB) e atrofia hipocampal (AH) sobre esses sintomas foi poucoexplorado na literatura. Objetivo: Este estudo transversal objetiva descrever as características clínicas de uma amostracom extensas HSB, examinando a influência de diferentes graus de AH sobre os aspectos cognitivos, comportamentaise funcionais. Métodos: Cinquenta idosos atendidos em ambulatório (idade média: 76.86±8.70 anos; 58% mulheres;escolaridade média: 7.44±4.69 anos), com extensas HSB (escala modificada de Fazekas=3) e diferentes graus de AH (deacordo com a escala de de Leon) foram submetidos à avaliação cognitiva, funcional e comportamental. Resultados. Pacientescom AH leve-moderada a grave apresentaram piores pontuações no Mini-Exame do Estado Mental, Avaliação Cognitivade Cambridge, Estadiamento Clínico da Demência e Questionário de Atividades Funcionais de Pfeffer, em comparaçãocom indivíduos com AH ausente ou questionável. Apetite/Comportamento Alimentar foi o único grupo de sintomasneuropsiquiátricos associados à presença de AH em indivíduos com Comprometimento Cognitivo Vascular. Discussão:Embora a AH pareça apresentar impacto sobre desempenho cognitivo e funcional, parece apresentar pouca influência sobresintomas comportamentais em pacientes com extensas HSB.

ABSTRACT

Alzheimers disease (AD) represents the most prevalent neurodegenerative disorder that causes cognitive decline in old age. In its early stages, AD is associated with microstructural abnormalities in white matter (WM). In the current study, multiple indices of diffusion tensor imaging (DTI) and brain volumetric measurements were employed to comprehensively investigate the landscape of AD pathology. The sample comprised 58 individuals including cognitively normal subjects (controls), amnestic mild cognitive impairment (MCI) and AD patients. Relative to controls, both MCI and AD subjects showed widespread changes of anisotropic fraction (FA) in the corpus callosum, cingulate and uncinate fasciculus. Mean diffusivity and radial changes were also observed in AD patients in comparison with controls. After controlling for the gray matter atrophy the number of regions of significantly lower FA in AD patients relative to controls was decreased; nonetheless, unique areas of microstructural damage remained, e.g., the corpus callosum and uncinate fasciculus. Despite sample size limitations, the current results suggest that a combination of secondary and primary degeneration occurrs in MCI and AD, although the secondary degeneration appears to have a more critical role during the stages of disease involving dementia.
