Envelhecimento e doenças neurodegenerativas crônicas na Amazônia brasileira: implantação de novas metodologias de avaliação em pacientes com declínio cognitivo leve e doença de Alzheimer

Em 2025 o número de idosos no mundo irá dobrar e por volta de 2050 alcançará dois bilhões de indivíduos, estando a maioria em países desenvolvidos. A doença de Alzheimer (DA) é a quarta doença que mais compromete a qualidade de vida dos idosos. Este trabalho pretende sugerir novas metodologias de avaliação de pacientes com declínio cognitivo e doença de Alzheimer, apresentando uma versão brasileira a partir da versão original em língua inglesa intitulada “Test Your Memory” TYM (“teste sua memória- TSM), bem como mostrar os resultados do desempenho dos idosos na bateria de testes neuropsicológicos de Cambridge (CANTAB). Trata-se de estudo analítico, transversal retrospectivo do tipo caso-controle, realizado em pacientes do ambulatório de Geriatria do Hospital Universitário João de Barros Barreto, e em voluntários da comunidade no período de janeiro de 2009 a janeiro de 2011. Participaram 95 indivíduos com 65 ou mais anos de idade, divididos em 3 grupos: Alzheimer (DA, n=21), declínio cognitivo (DCL, n=31) e controle (n=43). Foram excluídos pacientes com história de acidente vascular encefálico (AVE), depressão primária, trauma cranioencefálico, outras demências, outras patologias neuropsiquiátricas e déficits visuo-auditivos limitantes. Os participantes foram submetidos à avaliação inicial, triagem com GDS-5 e DSM-IV, ao Questionário Internacional de Atividades Físicas (IPAQ), testes neuropsicológicos da bateria CERAD, teste do relógio, TSM (versão adaptada para o Português) e a bateria de Alzheimer do CANTAB. A análise estatística foi realizada empregando-se ANOVA, um critério, definindo-se o valor p<0,05 como significante. Houve predomínio em todos os grupos de indivíduos do gênero feminino, de cor parda, na faixa etária de 70 a 79 anos. A média de pontuação do MEEM entre os três grupos foi diferente (controle: 26,6±2,2; DCL: 25,1±2,6; DA: 17,3±4,9; p<0,05), entretanto o TSM mostrou ser uma ferramenta de triagem mais confiável para distinguir os pacientes DCL dos DA (controle: 42,4±5; DCL: 35,5±7,7; DA: 25,7±8; p<0,01). Na lista de palavras do CERAD, teste do relógio, TNBR e na fluência verbal fonológica os três grupos apresentaram diferenças significantes na média de pontos obtidos. A média da pontuação total no TSM foi significativamente menor nos grupos DCL e DA do que no grupo controle, e no grupo DA em relação ao DCL. Os testes e medidas do CANTAB que separam os três grupos pelo desempenho obtido são: RVP A‟, número de tentativas para o sucesso e total de erros na fase de 6 figuras do PAL. Foram encontradas boas correlações entre o TSM e outros testes, principalmente com o MEEM (Coeficiente de Pearson, r = 0,79; p<0,0001) e teste do relógio (r = 0,76; p<0,0001), bem como boa correlação entre as medidas do PAL e a pontuação do TSM e o MEEM. O nível de atividade física no grupo controle foi maior do que em todos os outros grupos. Ao ser correlacionado o nível de atividade física e o desempenho nos testes cognitivos, não foram observadas diferenças significativas nos diferentes grupos, exceto pela evocação de palavras no grupo DCL. Tomados em conjunto os resultados sugerem que a aplicação de testes neuropsicológicos automatizados associados aos testes da rotina clínica e ao TSM aumentam a resolução e a confiabilidade das análises particularmente no estágio inicial das síndromes demenciais onde a precocidade e a precisão diagnóstica são fundamentais para orientar as ações terapêuticas, sejam elas medicamentosas e/ou comportamentais.

Análise citogenética como bioindicador para pacientes com diagnóstico sugestivo de Alzheimer

A doença de Alzheimer (DA) é uma doença neurodegenerativa que provoca morte neuronal e consequente perda progressiva das funções cognitivas, reduzindo as capacidades de trabalho, interferindo na relação social e no comportamento do paciente. Entre as doenças causadoras de demência, a DA é a mais incidente que as de cunho vascular, numa proporção de 4:1, respectivamente. Além das terapias farmacológicas, os métodos diagnósticos auxiliam na identificação precoce da doença auxiliando o tratamento prévio, assim diminuído a progressão da doença. Atualmente estudos citogenéticos vêm demonstrando alterações cromossômicas em portadoras da DA e podem auxiliar no diagnósticos da doença. O objetivo desse trabalho foi verificar o potencial da análise cariotípica de linfócitos do sangue periférico como bioindicador diagnostico da doença de Alzheimer. Para a realização deste trabalho, utilizamos dois grupos de mulheres com 65 anos ou mais, sendo um grupo com (10) portadoras de DA e outro grupo (10) normais. Cada indivíduo foi submetida ao questionário socioeconômico, teste de rastreio cognitivo (MEEM) e à coleta de sangue venoso para cultura de linfócitos e análise cromossômica. Nossos resultados demonstram que o grupo de mulheres portadoras da DA apresentaram elevada taxa de monossomia e trissomia em relação às mulheres normais. Através de estudo de anamnese via questionário, verificamos o estilo de vida de ambos os grupos. Quando comparado a relação das alterações cromossômicas com o nível cognitivo do grupo DA, nós evidenciamos uma tendência inversamente proporcional entre o número de monossomia/trissomia e o desempenho cognitivo. Outro aspecto de nossas análises foi o papel de cada cromossomo ligado à DA. Os cromossomos 1, 14 e 21 não apresentaram trissomia e na verificação da frequência de monossomia, cada cromossomo possui frequência abaixo de 3 % de aneuploidia, ou seja, os cromossomos estudados não possuem uma grande representatividade nas alterações cromossômicas encontradas no estudo.

Uso de aparelho de amplificação sonora individual por idosos: estudo SABE - saúde, bem- estar e envelhecimento

PURPOSE: Describe hearing aid use by the elderly population in the city of São Paulo and identify associated factors. METHODS: A cross-sectional, descriptive, quantitative study integrated with the SABE (health, well-being and aging) project developed in 2006. A total of 1.115 individuals aged 65 or over were interviewed. Sample selection occurred in two stages, with replacement and probabilities proportional to the population to complement those aged 75 or over. Structured questionnaires and validated instruments were used. The data were weighted, the Rao-Scott test was used for univariate analysis and backward stepwise logistic regression was used for multivariate analysis, performed on Stata 10® software. RESULTS: Three hundred and seventy-seven subjects (30.4%) were classified as hearing impaired and 10.1% of these reported using hearing aids. To acquire the devices, 78.8% used their own resources and 16.9% acquired them through the Brazilian public health system (SUS). Among non-users of hearing aids, 16.6% reported prior indication; however, 8.6% were unable to adapt to the device and 8.0% could not afford to acquire one. Hearing aid use was associated with lower prevalence of probable dementia. CONCLUSION: The low number of hearing aid users indicates the difficulties elderly people face in acquiring them and/or that the health services face in effectively helping them to adapt. These findings may influence the quality of life of elderly with hearing impairment, given the association with probable dementia revealed by this study.

Análise de protocolos com intervenção motora domiciliar para pacientes com doença de Alzheimer: uma revisão sistemática

The regular practice of physical therapy is indicated as a non-pharmacological treatment of Alzheimer's disease by promoting cognitive, behavioral and functional benefits. However, little is known about the protocols with home-based motor intervention for this population. Thinking about it, this review aimed to investigate and analyze the protocols for home-based motor intervention for elderly with Alzheimer's disease described in scientific articles. A systematic search was performed in the following databases: Web of Science, PubMed, PsycINFO, and Scopus, using the following keywords and Boolean operators: home-based exercise OR home-based physical exercise OR home-based physical fitness OR home-based rehabilitation OR home-based physical therapy OR home-based physical activity OR home-based engine Intervention and AD OR Alzheimer's disease OR AlzheimerOR Alzheimer's dementia. We also conducted a manual search of reference lists of selected articles. Of the five articles that met the inclusion criteria adopted, three performed a protocol for home motor intervention, achieving good compliance with the program, improvement of general health and reduction of depressive symptoms. The other two studies were limited to describing the protocols. Although more studies are needed, with detailed protocols, this review allowed to show that protocols for home motor intervention can also produce positive effects for both patients and caregivers.

New treatment strategies for Alzheimer's disease: is there a hope?

Alzheimer's disease (AD) is a progressive and irreversible neurodegenerative disease, and corresponds to the most common cause of dementia worldwide. Although not fully understood, the pathophysiology of AD is largely represented by the neurotoxic events triggered by the beta-amyloid cascade and by cytoskeletal abnormalities subsequent to the hyperphosphorylation of microtubule-associated Tau protein in neurons. These processes lead respectively to the formation of neuritic plaques and neurofibrillary tangles, which are the pathological hallmarks of the disease. Clinical benefits of the available pharmacological treatment for AD with antidementia drugs (namely cholinesterase inhibitors and memantine) are unquestionable, although limited to a temporary, symptomatic support to cognitive and related functions. Over the past decade, substantial funding and research have been dedicated to the search and development of new pharmaceutical compounds with disease-modifying properties. The rationale of such approach is that by tackling key pathological processes in AD it may be possible to attenuate or even change its natural history. In the present review, we summarize the available evidence on the new therapeutic approaches that target amyloid and Tau pathology in AD, focusing on pharmaceutical compounds undergoing phase 2 and phase 3 randomized controlled trials.

A percepção da doença de Alzheimer pelos estudantes da F.F.C. Júlio de Mesquita Filho da UNESP, Marília

Alzheimer’s disease (AD) accounts for approximately 56% of all cases of dementia. The present study aimed to report the perception of AD by students of Physiotherapy, Speech Therapy and Occupational Therapy from Faculty of Philosophy and Science “Julio de Mesquita Filho” – UNESP – Marília, with regard to the symptoms, diagnosis and treatment, between 2011 and 2012. The questionnaire with open and closed questions was administered to 101 students, using as a criterion for exclusion those who refused to answer the survey and / or not signed the informed consent form. After the questionnaire application, the answers have undergone quantitative analysis, checking which information and concepts about Alzheimer’s disease these students acquired during the undergraduate years. The data shows that although students have knowledge about the signs and symptoms of the disease, few mention the importance of family, the caregiver and the relationship of the disease with dependence that commonly reaches this population.

Análise do equilíbrio e da qualidade de vida de idosos com Alzheimer e a influência na qualidade de vida do Cuidador

With the growing aging population will be an increase of chronic degenerative diseases such as dementia. Among the various forms of dementia Alzheimer’s disease (AD) is the most prevalent. In individuals with AD, there is a loss in the processing of sensory information, which may aggravate the imbalance and falls. As the disease progresses, the individual lose the ability to function independently, becoming dependent on a caregiver. This study aimed to analyze the balance of the mental state and quality of life of individuals with AD, to determine whether a correlation exists between these variables and analyze the influence on quality of life of caregivers. This study was conducted with thirty individuals (82.86 ± 9.07 years) with AD, both sexes, and their caregivers. The evaluation of the balance was accomplished by the Scale of Functional Balance of Berg (EEFB), the cognitive function for the Mini-exam of the Mental State (MEEM), and the quality of life (QV) for the scale “life Quality - Disease of Alzheimer “ (QdV - DA) that is composed for three versions: patient, caregiver and family The data were analyzed by coefficient of correlation of Spearman. The balance analyses (EEFB=32,17 ± 13,26 points) shows increased in the risk of falls in the elderly and negative correlation (R = - 0,55, p <0,01) with age and good correlation with MEEM (R=0,63 p <0,01). Already in relation of the MEEM and QV, can observed correlation between the familiar version and the MEEM ((R=0,40 p=0,02). In Relation the versions of the QV questionnaire, found significant correlation among: QdV-DA patient X caregiver (R=0,41 p=0,02), QdV-DA patient X family (R=0,40 p=0,03). In this way we can conclude that the individuals with DA, appraised in this study, present a deficit in the balance, so much related with the age as with to the cognitive decline, and the greater the cognitive decline worse the impression of caring about the QOL of their family, and still, that the worsening in the quality of the patient’s life contemplates in a worsening in the quality of your caregiver’s life.

Níveis de sobrecarga, ansiedade e depressão de cuidadores de pacientes com doença de Alzheimer participantes e não participantes de grupos de apoio

Currently , as a result of the significant increase in the number of elderly, one can observe an increase in the number of chronic diseases , among them Alzheimer's disease (AD) , which affects both patients and their caregivers , that due care with the patient , just overwhelmed , anxious and depressed. Therefore, this study aims to draw a profile of caregivers of Alzheimer's patients, correlating the physical activity of patients with levels of overload, anxiety, depression caregivers. For both sample consisted of 40 patients with AD to characterize the physical activity levels and perform activities of daily living. In addition, we evaluated 40 caregivers. Patient assessment was made through a medical history, beyond the score Clinical Dementia Rating (CDR), Mini - Mental State Examination (MMSE), Modified Baecke Questionnaire for Older Adults (MBQ) , Functional Activities Questionnaire PFEFFER (QAFP) , and the Self Perception Performance in Activities of Daily Living (EAPAVD). For assessing the caregiver was also used an interview, then the Neuropsychiatric Inventory (NPI), anxiety and depression scale (HAD) Scale and the Zarit caregiver burden (Zarit). The data were processed using descriptive procedures for the analysis of characterization of samples, such as cognitive screening and physical activity level and profile of caregivers. There was a normal distribution of the data using the Shapiro Wilk, For data with normal distribution were used parametric descriptive procedures using One Way ANOVA to compare groups and applying a post hoc Bonferroni. As for the data that showed the destruction not normal was used to standardize the test by Z -score , and then treated by means of parametric statistical procedures , as presented earlier . The Pearson correlation was used to identify possible associations between variables. It was assumed significance level of 5 % (p ≤ 0.05) for all analyzes. Given these results, we conclude that...

Atividade física e sintomas depressivos em cuidadores de idosos com demência de Alzheimer

The Alzheimer's dementia (AD) is a chronic, neurodegenerative and progressive disorder, characterized by cognitive decline, affecting brain functions like memory, reasoning and communication, occurrence of behavioral disturbances and difficulty in performing activities of daily living (ADLs). These conditions lead to patient’s dependence, which can cause depressive symptoms in caregivers, due to physical and mental burden caused by of the difficulties of the act of caring. Whereupon, it became necessary to find strategies to improve the caregivers’ quality of life. An interesting hypothesis is that physical activity can be considered a non-pharmacological alternative in reducing depressive symptoms, being an important factor for maintaining the physical and mental well-being of the general population, especially on positive changes in mood and social interaction. This study aimed to analyze the effects of a physical activity protocol on depressive symptoms and burden of caregivers of patients with AD. This experimental study, of longitudinal character, comprised a sample of 19 caregivers, of both genders, divided into two groups: a) intervention group – IG (10 caregivers who participated in a physical activity protocol) and b) control group – CG (9 caregivers who didn’t participate in the physical activity protocol). This protocol, which worked the components of functional ability and social interaction of participants, was held three times a week, being 48 sessions of 60 minutes each, for 16 weeks. Data collect was performed at pre and post-intervention for both groups. The assessment instruments used were: a) Zarit Burden Interview, b) Hospital Anxiety and Depression Scale (HAD) and c) battery of motor tests of the American Alliance for Health Physical Education Recreation and Dance (AAHPERD). Nonparametric statistics was used, with intra-group comparison by Wilcoxon test... (Complete abstract click electronic access below)
