OBJETIVO: traduzir e adaptar protocolo desenvolvido por pesquisadores alemães, adequando-o às características fonéticas e linguísticas do português falado no Brasil. Caracterizar os componentes de fala mais alterados na população com doença de Parkinson, comparando-os com grupo de sujeitos normais na mesma faixa etária. MÉTODOS: realizou-se a tradução e adaptação do protocolo. Posteriormente foram avaliados 21 pacientes com diagnóstico neurológico de Doença de Parkinson nos estágios Hoehn &Yarh, entre 2 e 3, e 10 sujeitos normais. O protocolo incluía avaliação da respiração, fonação, ressonância, articulação, prosódia e a análise acústica dos parâmetros vocais. RESULTADOS: o protocolo mostrou-se de fácil aplicação clínica. Nos sujeitos com doença de Parkinson foram observadas alterações predominantes na fonação (85,9%) e articulação (42,9%). CONCLUSÃO: o estudo demonstrou ser o protocolo uma ferramenta eficiente para a avaliação da disartria em pacientes com doença de Parkinson.

Objective: To determine correlations between age and metabolic disorders in Parkinson's disease (PD) patients. Methods: This observational cross-sectional study included brief tests for dementia and the Mattis test. Signals of metabolic syndrome were evaluated. Results: There was no significant effect from the presence of hypertension (OR=2.36 for patients under 65 years old and OR=0.64 for patients over 65), diabetes or hypercholesterolemia regarding occurrences of dementia associated with PD (24% of the patients). The study demonstrated that each year of age increased the estimated risk of dementia in PD patients by 9% (OR=1.09; 95%Cl: 1.01-1.17). Conclusion: There was no evidence to correlate the presence of metabolic syndrome with the risk of dementia that was associated with PD. The study confirmed that dementia in PD is age dependent and not related to disease duration.

Depression is a frequently observed neuropsychiatric phenomenon in Parkinson's disease (PD) and it has been lately considered as a manifestation of such disease. The aim of the study was to investigate the relationship between depression and clinical aspects of PD and to assess the impact of the co-occurrence of such condition on the burden imposed by PD. Fifty Outpatients diagnosed with idiopathic PD according to the London Brain Bank criteria were examined. PD was evaluated using Hoehn & Yahr staging (H&Y), United Parkinson's Disease Rating Scale (UPDRS) and Schwab & England (S&E) functional capacity evaluation. A semi-structured clinical interview was used. The diagnosis of PD was made by neurologist experts on movement disorders, and the diagnosis of depression was trade by a psychiatrist, according to the ICD-10 diagnostic criteria. Depressive symptoms were additionally measured using the Montgomery-Asberg Depression Scale. The analysis of quantitative data was performed using descriptive statistics, Univariate linear regression, T-Student Test and ANOVA. Seventeen (34%) patients were diagnosed as clinically depressed and, when compared to the non-depressed ones, presented the following results: H&Y: 3.2 vs. 2.8; UPDRS total: 75.7 vs. 65.3; S&E: 53.5% vs. 65.8% and PD duration: 114.4 months vs. 125.8 months. Depressed patients showed more advanced staging (H&Y), a more severe global clinical condition (UPDRS) and also a greater decrease in their functional capacity (S&E). These data reinforce the hypothesis that depression is associated to poorer functioning in patients with PD. (C) 2008 Elsevier B.V All rights reserved.

CONTEXTO: Os efeitos da levodopa na marcha de pacientes com Doença de Parkinson (DP) em terrenos desobstruídos são conhecidos, mas pouco se conhece sobre seus efeitos na marcha com obstáculos. OBJETIVO: Este estudo objetivou descrever, por meio de ferramenta cinemática, o comportamento locomotor de pacientes com DP e verificar as estratégias locomotoras, sem e sob o efeito da levodopa, durante a ultrapassagem de obstáculos de diferentes alturas. MÉTODO: Cinco pacientes com DP (Hoehn e Yahr= 2±0; idade= 68,4±5,7 anos) percorreram, andando, 10m e ultrapassaram um de dois obstáculos (alto= metade da altura do joelho e baixo= altura do tornozelo) posicionado no meio da passarela em duas sessões (em jejum e no pico de ação do medicamento). As seguintes variáveis foram coletadas e analisadas: distância horizontal pé-obstáculo (DHPO), distância vertical pé-obstáculo (DVPO); distância horizontal obstáculo-pé (DHOP) e velocidades médias, horizontais e verticais, nas fases de abordagem e aterrissagem (respectivamente, VHAO,VVAO; VHDO,VVDO). RESULTADOS: A ANOVA, por tentativa, revelou efeito principal de obstáculo para DVPO (F1,49=15,33; p< 0,001), para VVAO (F1,49= 82,184; p< 0,001), para VHDO (F1,49= 15,33; p< 0,001) e para VVDO (F1,49= 31,30; p< 0,001); e efeito principal de medicamento para DVPO (F1,49= 6,66; p< 0,013) e para VVAO (F1,49= 10,174; p< 0,002). CONCLUSÕES: Pacientes foram mais perturbados pelo obstáculo alto. Os sintomas da DP (bradicinesia e hipocinesia) foram diminuídos com o medicamento, evidenciando aumento geral da velocidade da perna de abordagem e da margem de segurança sobre os obstáculos. Pacientes com DP, independente da condição de medicamento, apresentaram um comportamento que garantiu segurança e estabilidade na marcha.

This study aimed at evaluating and describing the QoL and its association with the severity of disease among Brazilian Parkinson's disease (PD) patients. In this cross-sectional study 68 PD patients were interviewed using the World Health Organization Quality of Life instrument Short Form (WHOQOL-BREF) and the Hoehn-Yahr (HY) scale. Analysis of variance, chi(2), Kruskal-Wallis and Mann-Whitney U-tests, Spearman and Cronbach reliability coefficients were used to analyze the data. The results indicate: (1) physical capacity was the domain that showed the most deterioration; (2) severity of PD is associated with QoL measured by WHOQOL-BREF; (3) overall QoL, working capacity, activities of daily living (ADL) and self-esteem are affected in both transitional periods in the progression of PD (mild to moderate and moderate to advanced). Satisfaction with general health, pain, energy, positive feelings, personal relationship and satisfaction with home are affected in the first period of transition while mobility, body image, sexual activity and access to information are affected in the second. This study mainly shows specific facets that are affected depending on the specific periods of PD progression, which can help to understand the impact of the disease, the effectiveness of care, and the demand for health care resources.

Background: Hyperhomocysteinemia is a major risk factor for cerebral and peripheral vascular diseases, as well as cortical and hippocampal injury, including an increased risk of dementia and cognitive impairment. Elevated serum homocysteine (Hcy) concentrations are common in patients with Parkinson's disease (PD) who have been treated with levodopa; however, physical exercises can help reduce Hcy concentrations. The aim of the present study was to compare serum Hcy levels in patients with PD who partook in regular physical exercises, sedentary PD patients, and healthy controls.Methods: Sixty individuals were enrolled in the present study across three groups: (i) 17 patients who did not partake of any type of exercise; (ii) 24 PD patients who exercised regularly; and (iii) 19 healthy individuals who did not exercise regularly. All participants were evaluated by Hoehn and Yahr scale, the Unified Parkinson's Disease Rating Scale (UPDRS) and Schwab and England scale (measure daily functionality). The serum levels of Hcy were analyzed by blood samples collected of each participant. An analysis of variance and a Tukey's post hoc test were applied to compare and to verify differences between groups. Pearson's correlation and stepwise multiple regression analyses were used to consider the association between several variables.Results: Mean plasma Hcy concentrations in individuals who exercised regularly were similar to those in the healthy controls and significantly lower than those in the group that did not exercise at all (P = 0.000). In addition, patients who did not exercise were receiving significantly higher doses of levodopa than those patients who exercised regularly (P = 0.001). A positive relationship between levodopa dose and Hcy concentrations (R(2) = 0.27; P = 0.03) was observed in patients who did not exercise, but not in those patients who exercised regularly (R(2) = 0.023; P = 0.15).Conclusions: The results of the present study suggest that, even with regular levodopa therapy, Hcy concentrations in PD patients who exercise regularly are significantly lower than in patients who do not exercise and are similar Hcy concentrations in healthy controls.
