Objective To verify the effects of a systematized multimodal exercise intervention program on frontal cognitive function, postural control, and functional capacity components of individuals with Alzheimer's disease (AD).DesignNonrandomized controlled trial with pre- and posttraining tests in a training group and a control group.SettingKinesiotherapy program for seniors with AD, SAo Paulo State University.ParticipantsConvenience sample of older adults with AD (n=30) were assigned to a training (n=14; aged 78.67.1) and a control (n=16; aged 77.06.3) group.InterventionThe intervention program was structured with the aim of simultaneously promoting better balance and frontal cognitive capacity. The participants attended a 1-hour session three times a week for 16weeks, whereas the control group did not participate in any activity during the same period.MeasurementsFrontal cognitive function was evaluated using the Montreal Cognitive Assessment, the Clock Drawing Test, the Frontal Assessment Battery, and the Symbol Search Subtest. Postural control (center of pressure area) was analyzed under four dual-task conditions. Functional capacity components were analyzed using the Timed Up and Go Test, the 30-second sit-to-stand test, the sit-and-reach test, and the Berg Functional Balance Scale.ResultsIntervention group participants showed a significant increase in frontal cognitive function (P<.001, partial (2)=0.838), with less body sway (P=.04, partial (2)=0.04) during the dual tasks, and greater functional capacity (P=.001, partial (2)=0.676) after the 16-week period.ConclusionIntervention participants performed better on dual-task activities and had better postural balance and greater functional capacity than controls.

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.

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.

Neste trabalho, foi feita uma revisão de importantes aspectos associados às bases neurobiológicas da Doença de Alzheimer, por meio de um levantamento bibliográfico sobre o assunto. A Doença de Alzheimer (DA) é uma doença neurodegenerativa que acomete geralmente pessoas acima de 65 ou 70 anos. Em pacientes com DA, nota-se a ocorrência de atrofia progressiva de várias áreas cerebrais, responsáveis pela perda de memória e de outras funções cognitivas, além da diminuição da capacidade para realizar atividades rotineiras. Inicialmente, a atrofia ocorre no lobo temporal, especialmente nas regiões responsáveis pela memória (hipocampo, córtex entorrinal) e, posteriormente, em regiões como o córtex parietal e córtex frontal. O declínio progressivo e persistente de memória recente pode ser verificado já na fase inicial da doença e, progressivamente, entram em declínio outras funções cognitivas, resultando em um comprometimento cognitivo global. Os mecanismos envolvidos na degeneração cerebral na Doença de Alzheimer estão relacionados com a neuropatologia característica da DA. Lesões cerebrais específicas levam a morte de neurônios e sinapses, e estão relacionadas a presença de placas amilóides e emaranhados neurofibrilares. Essas placas e emaranhados acometem principalmente as camadas piramidais do córtex cerebral e são responsáveis por degenerações sinápticas intensas, tanto em nível hipocampal quanto neocortical (BRAAK & BRAAK, 1991). À medida que os neurônios morrem, são perdidos sinais de entrada sinápticos em regiões do encéfalo que são críticas para a função cognitiva e de memória normal

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...

A Doença de Alzheimer (DA) tem sido conceituada como uma doença de caráter duplo, inicialmente por possuir um fenotípico clínico centrado na presença de uma demência progressiva que inclui comprometimento da memória como uma característica definitiva, além do envolvimento de outros domínios cognitivos ou habilidades. É caracterizada também por alterações neuropatológicas específicas que incluem lesões intraneuronais (emaranhados neurofibrilares) e extracelulares (placas senis), que podem ser acompanhados por perda sináptica e depósitos vasculares amiloides (Dubois et al, 2010). A constatação do processo neurodegenerativo se evidencia por meio da atrofia cerebral, especialmente, em hipocampo e córtex entorrinal constatada por neuroimagem (por exemplo, a ressonância magnética e tomografia computadorizada). Dentro desse conceito, esse estudo teve como objetivo fazer uma investigação geral com base na literatura especializada, com análise de artigos relevantes, referentes aos aspectos neurobiológicos associados à Doença de Alzheimer. Foram abordados tópicos como: atrofia cerebral, processo neurodegenerativo, biomarcadores, neuroimagem (com foco na escala de Urs et al.,2009) e aspectos clínicos

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)

A demência de Alzheimer (DA) constitui o tipo mais comum de demência. Déficits de memória caracterizam a doença e causam comprometimento de sua qualidade de vida. Sintomas depressivos são comuns na DA e associam-se a um contexto de perda da qualidade de vida. Atualmente a literatura apresenta poucos estudos envolvendo a temática atividade física na DA. O presente estudo poderá orientar novas investigações acerca da DA e auxiliar profissionais da área da saúde na orientação de cuidados para o paciente que visam reduzir sintomas depressivos e aumentar a qualidade de vida de pacientes e cuidadores. O objetivo do estudo foi analisar os efeitos da atividade física sistematizada sobre os sintomas depressivos e a qualidade de vida de idosos com demência de Alzheimer e de seus cuidadores. Dezesseis sujeitos com diagnóstico de DA foram avaliados no início e após seis meses pelos testes: Mini-Exame do Estado Mental (MEEM), escala de qualidade de vida (EQV) e Escala de Depressão em Geriatria (EDG). Seis participantes foram submetidos à sessões de um programa sistematizado de atividade física a ser realizado 3 vezes por semana, com duração de 60 minutos, por um período de 6 meses. Os demais formaram o grupo controle, que não realizou a intervenção motora. A análise dos dados consistiu da estatística descritiva, verificação da distribuição dos dados por meio do teste de Shapiro Wilk. Foi utilizada a Análise de Variância para medidas repetidas (ANOVA two-way) e o teste de correlação de Pearson. Admitiu-se nível de significância de 5% (p<0,05) para todas as análises. A ANOVA mostrou uma interação significativa entre grupos e momentos. O coeficiente de correlação de Pearson apontou que há relação entre as visões de qualidade de vida, e entre as mesmas e os sintomas...(Resumo completo, clicar acesso eletrônico abaixo)

Nos idosos, o andar tem sido associado com a preservação das funções cognitivas. Entretanto, pacientes com Demência de Alzheimer (DA), apresentam modulações durante o andar, decorrente das disfunções no lobo frontal, principalmente no córtex motor e declínio nas funções executivas. Contudo, a marcha de idosos com DA pode ser mais vulnerável na presença de uma tarefa dupla, pois esses idosos apresentam déficits nas ações que exigem planejamento, atenção e ajustes motores. Desse modo, o objetivo deste estudo foi analisar no paradigma da tarefa dupla os valores médios das variáveis espaciais e temporais do andar de pacientes com DA. A amostra do estudo foi composta por 19 idosos com DA, sendo 14 mulheres e 5 homens. Os pacientes com DA realizaram 5 tentativas das seguintes tarefas: andar livre sem tarefa dupla e andar livre com tarefa dupla. A tarefa dupla realizada pelos pacientes foi uma contagem regressiva iniciando do número vinte. As variáveis espaço-temporais foram coletadas através de um sistema optoeletrônico de análise do movimento. As variáveis analisadas foram comprimento da passada, largura do passo, duração da fase de suporte simples e duplo suporte, duração da passada e velocidade da passada. Para verificar as diferenças entre as condições experimentais no andar livre foi utilizado o teste t de Student pareado (p<0,05) com fator para tarefa. O teste t pareado revelou efeito da tarefa no comprimento da passada, largura do passo, suporte simples, duplo suporte, duração da passada e velocidade da passada. Os pacientes reduziram o comprimento e a velocidade da passada e aumentaram a largura do passo e as durações do suporte simples, duplo suporte e da passada na condição marcha livre com contagem em comparação com a marcha livre sem contagem. Concluiu-se que a tarefa dupla interfere nos parâmetros...(Resumo completo, clicar acesso eletrônico abaixo)

Falls among older people is a major clinical problem due to its high incidence, with consequent implications for the health and care costs. Elderly patients with dementia of Alzheimer type (AD) are more susceptible to falls due to the impairment of executive functions and gait, with the risk of falls 3 times higher than non-demented elderly. This study used a longitudinal design and aimed to analyze the effects of a regular and systematized physical activity program on the frequency of falls in patients with AD. Additionally, we aimed to correlate the frequency of falls with the executive functions and equilibrium, after and before the physical activity program. The study included 21 patients with clinical diagnosis of AD, divided into two groups: control group (CG), composed of 11 subjects not engaged in any systematized physical activity and training group (TG): 10 seniors who participated in the Cinesioterapia Functional and Cognitive in Elderly with Alzheimer's disease program (PRO-CDA). The physical activity program lasted four months, with weekly frequency of three times, with each session lasting 60 minutes. Were administered the Mini-Mental State Examination (MMSE) to assess cognitive functioning and global score of the Clinical Dementia Rating (CDR) to classify the severity of dementia. For the evaluation of executive functions were used the Clock Drawing Test (TDR) and Frontal Assessment Battery (FAB). In addition, we used the Functional Balance Scale, Berg test (EEFB) and Timed Up-and-Go (TUG) to assess the equilibrium and risk of falls. Falls were recorded by means of a questionnaire, which included the number of falls in the last four months. Analyzing the results, it was observed that TG obtained significant improvements in equilibrium and in executive functions, highlighting the beneficial effects of physical activity in these variables...
