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.

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.

This case study objectified investigating the symptomatology prevalence for depression (DP) and cognitive decline (CD) on institutionalized elderly’s; verifying the existence of correlations between DP and CD with age, gender and scholarity; and analyzing the possible correlations between symptomatology for DP and CD. For the realization of this research were selected, in two Elderly’s Long-Permanence Institutions (ELPIs), 24 subjects, which were classified according to gender, scholarity and age group. To verify the occurrence of CD, the Mini Mental State Examination (MMSE) was applied and, for the incidence of DP, the Geriatric Depression Scale (GDS) was applied. The data were tabulated and descriptively analyzed. For the study of the relations between quantitative variables, the Pearson correlation test was utilized and also the Spearmann test when necessary; for the comparison between two independent groups, the Student's t-test was utilized; for the verification of the association between gender, scholarity, DP and CD indicatives, the Pearson's X2 test and, due to theoretical restriction, the Fisher's exact test were utilized. The level of 5% probability was adopted for the rejection of nullity's hypothesis on all the tests. The research demonstrated that 50% of the research' subjects presented DP indicatives and 54.2% presented CD indicatives. Associations between: gender and DP (p = 0.414), gender and CD (p = 0.219), scholarity and CD (p = 0.527) were not observed. Positive regular correlation was verified between age and DP (r = 0.557; p = 0.005) and negative regular correlation was verified between DP and CD (r = -0.406; p = 0.049). The data suggest that DP might be a reaction to CD perceived by the subject. However, the hypothesis that indicates DP as a risk factor for CD and DM cannot be overruled, which suggests the importance of monitoring and treating depressive episodes on elderly populations.

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

Beside aging process comes the incidence of dementia and, among them Alzheimer's disease (AD) accounts for approximately 60% of cases. This disease is characterized as a neuropathology with unknown etiology that causes cognitive deficits and behavioral disorders. Caring for patients with AD can cause an overload, both physical and psychological, which can cause high levels of stress on the primary caregiver. It is necessary that the caregiver also receives attention and develop activities that promote health benefits, while providing moments of distraction from the task of caring. Nonpharmacological interventions may be favorable for improving health with consequent decreased on the levels of stress. The objective of this study was to conduct a systematic review of scientific papers that aimed to verify the effect of nonpharmacological interventions on stress levels in caregivers of patients with AD. To contamplate this goal was accomplished a systematic search in the following databases: Biological Abstracts, PsycINFO, PubMed/Medline, Web of Science, LILACS and SciELO. The following keywords and Boolean operators was used: “caregivers” OR “family” and “nonpharmacological interventions” OR “support groups” OR “therapies” AND “Alzheimer's disease” OR “Alzheimer's dementia” OR “Alzheimer” OR “elderly” AND “stress”. There were found 3studies that met inclusion criteria adopted for the present work, and none showed significant results for the variable stress. It is not possible to affirm, according to the studies, that nonpharmacologial interventions programs for caregivers of patients with AD are effective to influence and to control the stress. However, studies show benefits for other variables such as self-efficacy and confidence in relation to care... (Complete abstract click electronic access below)
