Abstract Background Evaluation and treatment of primary and secondary headaches is a global public health challenge. Recognizing the epidemiological impact of headaches, a group of researchers linked to the Brazilian Headache Society proposed the Brazilian Headache Registry and drew up its initial protocol. Objective Here we describe the methods and preliminary data obtained from the pilot study. Methods This was a multicenter longitudinal observational study conducted between September 2020 and August 2021. Prospective data were collected in three specialist centers for headache care in states in southern and southeastern Brazil. Patients aged 18 years or older who sought care for headache in tertiary centers and who agreed to participate in the study, were considered eligible. Results Sixty-six patients were included in the pilot study: 43 (65%) from Rio Grande do Sul state and 23 (35%) from Minas Gerais state. Overall, 90% were female, and the subjects' mean age was 38.2 ± 11.2 years. Primary headaches accounted for 85.3% of the diagnoses made. Among secondary headaches, medication overuse headache was the most frequent type (7.1%). Conclusions The pilot study showed the feasibility of the research protocol developed for tertiary centers. The Brazilian Headache Registry will form a source of longitudinal data with the aim of contributing to better characterization of the various phenotypes of patients with primary and secondary headaches, and to detailing the use of health resources and identifying predictors of better clinical outcomes.

Abstract Background Levodopa is the most used and effective medication for motor symptoms of Parkinson disease (PD), its long-term use is associated with the appearance of levodopa-induced dyskinesia (LID). Uric acid (UA) is believed to play an important neuroprotective role in PD. Objective To investigate if serum UA levels are related with the presence of LIDs in PD patients. Also, we investigated the associations among UA levels and clinical features of PD. Methods We enrolled 81 PD patients (dyskinesia = 48; no dyskinesia = 33) in the present study. A blood sample was collected to evaluate serum UA levels, clinical evaluation included the following instruments: Montreal Cognitive Assessment (MoCA), Beck Depression Inventory II (BDI-II), MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Hoehn and Yahr (HY), and the sub-item 4.1 of MDS-UPDRS IV (score ≥ 1). Additional relevant clinical information was obtained by a clinical questionnaire. Results Serum UA levels were lower in the dyskinesia group when compared with the no dyskinesia group. The same result was found in the UA levels of both men and women. The multivariate analysis showed lower uric acid levels were significantly associated with having dyskinesia (odds ratio [OR] = 0.424; 95% confidence interval [CI]: 0.221-0.746; p= 0.005). Additional analysis verified that serum UA levels are inversely correlated with depressive symptoms, disease duration, MDS-UPDRS IV and time spent with dyskinesia. A positive correlation was found with age at onset of PD symptoms. Conclusions The present study provides a possible role of serum UA levels in LID present in PD patients.

Resumo Antecedentes A levodopa é a medicação mais utilizada e eficaz para os sintomas motores da doença de Parkinson (DP); seu uso a longo prazo está associado ao aparecimento de discinesia induzida por levodopa (LID). Acredita-se que o ácido úrico desempenhe um importante papel neuroprotetor na DP. Objetivo Investigar se os níveis séricos de AU estão relacionados com a presença de LID em pacientes com DP. Além disso, investigamos as associações entre os níveis de AU e as características clínicas da DP. Métodos Foram incluídos 81 pacientes com DP (discinesia = 48; sem discinesia = 33) no presente estudo. Uma amostra de sangue foi coletada para avaliar os níveis séricos de AU, a avaliação clínica incluiu os seguintes instrumentos: Avaliação Cognitiva de Montreal (MoCA), Inventário de Depressão de Beck (BDI-II), MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Hoehn and Yahr (HY) e o subitem 4.1 da MDS-UPDRS IV (escore ≥ 1). Informações clínicas relevantes adicionais foram obtidas por meio de um questionário clínico. Resultados Os níveis séricos de AU foram menores no grupo com discinesia quando comparados ao grupo sem discinesia. O mesmo resultado foi encontrado nos níveis de AU de homens e mulheres. A análise multivariada mostrou que níveis mais baixos de ácido úrico foram significativamente associados a ter discinesia (odds ratio [OR] = 0,424; intervalo de confiança (IC) de 95%: 0,221-0,746; p= 0,005). Análises adicionais verificaram que os níveis séricos de AU estão inversamente correlacionados com sintomas depressivos, duração da doença, MDS-UPDRS IV e tempo gasto com discinesia. Uma correlação positiva foi encontrada com a idade de início dos sintomas da DP. Conclusões O presente estudo fornece um possível papel dos níveis séricos de AU na LID presente em pacientes com DP.

ABSTRACT Parkinson’s disease (PD) is a common neurodegenerative disease associated with cognitive impairment. The Montreal Cognitive Assessment (MoCA) has been used as a recommended global cognition scale for patients with PD, but there are some concerns about its application, partially due to the floor and ceiling effects. Objective: To explore the floor and ceiling effects on the MoCA in patients with PD in Brazil. Methods: Cross-sectional study with data from patients with PD from five Brazilian Movement Disorders Clinics, excluding individuals with a possible diagnosis of dementia. We analyzed the total score of the MoCA, as well as its seven cognitive domains. The floor and ceiling effects were evaluated for the total MoCA score and domains. Multivariate analyses were performed to detect factors associated with floor and ceiling effects. Results: We evaluated data from 366 patients with PD and approximately 19% of individuals had less than five years of education. For the total MoCA score, there was no floor or ceiling effect. There was a floor effect in the abstraction and delayed memory recall domains in 20% of our sample. The ceiling effect was demonstrated in all domains (80.8% more common in naming and 89% orientation), except delayed recall. Education was the main factor associated with the floor and ceiling effects, independent of region, sex, age at evaluation, and disease duration. Conclusion: The floor and ceiling effects are present in specific domains of the MoCA in Brazil, with a strong impact on education. Further adaptations of the MoCA structure for underrepresented populations may reduce these negative effects.

RESUMO A doença de Parkinson (DP) é uma doença neurodegenerativa comum associada ao declínio cognitivo. A Avaliação Cognitiva de Montreal (Montreal Cognitive Assessment — MoCA) tem sido usada como uma escala de cognição global recomendada para pacientes com DP, mas existem algumas preocupações sobre sua aplicação, em parte pelos efeitos solo e teto. Objetivo: Explorar os efeitos solo e teto na MoCA em pacientes com DP no Brasil. Métodos: Estudo transversal com dados de pacientes com DP oriundos de cinco Clínicas de Distúrbios de Movimento no Brasil, excluindo-se pessoas com possível diagnóstico de demência. Nós analisamos a pontuação total da MoCA, assim como a de seus sete domínios cognitivos. Os efeitos solo e teto foram avaliados para a pontuação total da MoCA e seus domínios. Foram feitas análises multivariadas para a detecção de fatores associados os efeitos solo e teto. Resultados: Nós avaliamos dados de 366 pacientes com DP, e aproximadamente 19% das pessoas tinham menos que cinco anos de escolaridade. Para a pontuação total do MoCA, não houve efeito solo ou teto. Houve efeito solo nos domínios abstração e memória de evocação tardia em 20% de nossa amostra. O efeito teto foi demonstrado em todos os domínios (80,8% mais comum em nomeação e 89% orientação), com exceção de memória de evocação tardia. A educação foi o principal fator associado aos efeitos solo e teto, independentemente de região, sexo, idade na avaliação e duração da doença. Conclusão: Os efeitos solo e teto estão presentes em domínios específicos da MoCA no Brasil, com forte impacto da educação. Adaptações adicionais à estrutura da MoCA para populações vulneráveis podem reduzir esses efeitos negativos.

Abstract Background Depression is an important nonmotor symptom of Parkinson's disease (PD) and has been associated with the motor symptoms in these individuals. Objectives To determine whether there are relationships between depressive symptoms and abnormalities in axial postural alignment and axial motor deficits, especially postural instability, and trunk rigidity in PD. Methods In this cross-sectional study, 65 individuals were evaluated using the Beck Depression Inventory-II (BDI-II) for the analysis of depressive symptoms and underwent a postural assessment of head, trunk, and hip sagittal alignment through computerized photogrammetry. The MDS-UPDRS was used to assess clinical aspects of PD, the Trunk Mobility Scale was used to assess axial rigidity, and the MiniBESTest to assess balance. To determine the relationship between depressive symptoms and postural alignment, multiple linear regression analysis was performed. Results The participants with depressive symptoms had more severe motor deficits as well as greater trunk rigidity and worse postural instability (p < 0.05). When the postural angles were compared between men and women using Student's t-test, it was found that men had greater flexion angles of the head (p = 0.003) and trunk (p = 0.017). Using multiple linear regression analysis corrected for the age and sex of the participants, we verified that the anterior trunk inclination was significantly larger in the PD population with depressive symptoms (R2 = 0.453, β = 0.116, and p = 0.045). Conclusion PD individuals with depressive symptoms have more severe flexed trunk posture, mainly in older men. Additionally, more severe depressive symptoms are associated with worsening postural instability, trunk rigidity and motor deficits in this population.

Resumo Antecedentes A depressão é um sintoma não motor importante da doença de Parkinson (DP) e tem sido associada aos sintomas motores nesses indivíduos. Objetivos Determinar se existem relações entre sintomas depressivos e anormalidades no alinhamento postural axial e déficits motores axiais, especialmente instabilidade postural e rigidez de tronco na DP. Métodos Neste estudo transversal, 65 indivíduos foram avaliados pelo BDI-II para análise de sintomas depressivos e submetidos à avaliação postural do alinhamento sagital de cabeça, tronco e quadril por meio de fotogrametria computadorizada. A MDS-UPDRS avaliou os aspectos clínicos, TMS avaliou rigidez axial e o MiniBESTest equilíbrio. Para determinar a relação entre sintomas depressivos e alinhamento postural, realizou-se uma análise de regressão linear múltipla. Resultados Os participantes com sintomas depressivos apresentaram déficits motores mais graves, bem como maior rigidez de tronco e pior instabilidade postural (p < 0,05). Quando comparados os ângulos posturais entre homens e mulheres pelo teste t de Student, verificou-se que os homens apresentaram maiores graus de flexão da cabeça (p = 0,003) e do tronco (p = 0,017). Por meio da análise de regressão linear múltipla corrigida para a idade e sexo dos participantes, verificamos que a inclinação anterior do tronco foi significativamente maior nos indivíduos com DP com sintomas depressivos do que sem sintomas depressivos (R2 = 0,453, β = 0,116 e p = 0,045) Conclusão Indivíduos com DP com sintomas depressivos apresentam postura de tronco flexionado mais severa, principalmente em homens mais idosos. Além disso, os sintomas depressivos mais graves pioram significativamente a instabilidade postural, a rigidez do tronco e os déficits motores nessa população.

Abstract Background Hyposmia is one of the most common, as well as the first nonmotor condition in Parkinson disease (PD). The sniffin sticks test (SST) evaluates three different aspects of olfactory function: threshold (T), discrimination (D), and identification (I). The sum of the scores of these three subtests produce a global score of olfaction, the Threshold-Discrimination-Identification (TDI) score. Objective The aim of this study was to investigate if the TDI score or one of its subtests is better to discriminate PD patients from controls. Methods We recruited 27 PD patients and 17 healthy age-matched controls (HC) who were evaluated through a clinical interview, the Montreal Cognitive Assessment and Movement Disorders Society – Unified Parkinson Disease Rating Scale. The olfaction was assessed using the complete SST. Results The performance of PD patients on the olfactory test was significantly worse when compared with the HC (T: 3.0 vs. 6.5, p < 0.001; D: 8.1 vs. 11.2, p <0.001; I: 7.3 vs. 11.7, p < 0.001; TDI: 18.8 vs. 29.9, p < 0.001). The prevalence of olfaction impairment in our study (PD: 100%, and HC: 56%) was greater than that found in the literature. Cognition influenced the performance on TDI. The olfactory subtests were impaired proportionally between patients and controls. Furthermore, D and I were correlated, but only in PD patients. The TDI showed a tendency to better discriminate PD patients from HC, when compared with its subtests. Conclusions Although the complete olfactory evaluation is time consuming, it seems to be a superior tool to identify olfaction impairment in PD patients, when compared with the isolated subtests.

Resumo Antecendentes Hiposmia é um dos sintomas mais comuns da doença de Parkinson (DP), além de ser um de seus primeiros sintomas não-motores. O Sniffin Sticks Test avalia três diferentes aspectos da função olfatória: limiar (L), discriminação (D) e identificação (I). A soma dos escores desses três subtestes produz um escore global do olfato, o Threshold-Discrimination-Identification (TDI). Objetivo O objetivo deste estudo foi investigar se oTDI ou um de seus subtestes seria melhor em discriminar pacientes com DP de controles saudáveis. Métodos Foram recrutados 27 pacientes com DP e 17 controles saudáveis de mesma faixa etária, que foram avaliados através de uma entrevista clínica, a Montreal Cognitive Assessment e Movement Disorders Society – Unified Parkinson Disease Rating Scale. O olfato foi examinado através da bateria completa do Sniffin Sticks Test (SST). Resultados Os pacientes com DP tiveram pior performance no teste olfatório quando comparados com os controles (L: 3,0 vs. 6,5; p < 0,001; D: 8,1 vs. 11,2; p <0,001; I: 7,3 vs. 11,7; p <0,001; TDI: 18,8 vs. 29,9; p < 0,001). A prevalência de comprometimento olfatório no nosso estudo (DP: 100%, e controles: 56%) foi maior do que a reportada na literatura. A cognição influenciou a performance no TDI. Os subtestes olfatórios foram afetados proporcionalmente entre pacientes e controles. Além disso, D e I se correlacionaram, mas apenas em pacientes de DP. O TDI mostrou uma tendência em melhor discriminar pacientes de DP dos controles, quando comparado com os seus subtestes. Conclusões Embora a avaliação olfatória completa consuma tempo, ela parece ser superior aos subtestes isolados para identificar comprometimento olfatório em pacientes com DP.

Abstract Background The coexistence of amyotrophic lateral sclerosis (ALS) with clinical forms of Parkinson disease (PD), although uncommon, is found to a greater degree than one would expect by chance. The pathological mechanisms of ALS and PD are still not fully understood, and the coexistence of these two diseases suggests that they could share mechanisms in common. Objective Here we present a sample of patients with clinically definitive or probable ALS who were evaluated with single-photon emission computed tomography SPECT/TRODAT and compared with non-ALS controls. Methods Patients with clinically definite or probable ALS were assessed with the amyotrophic lateral sclerosis functional rating scale (ALSFRS) to define severity and had their demographic data collected. The TRODAT results of patients with ALS were compared with those of patients with a diagnosis of PD with less than 10 years of duration, and with patients with a diagnosis of others movement disorders not associated with neurodegenerative diseases. Results A total of 75% of patients with ALS had TRODAT results below the levels considered normal; that was also true for 25% of the patients in the control group without neurodegenerative disease, and for 100% of the patients in the PD group. A statistically significant difference was found between patients with ALS and the control group without neurodegenerative disease in the TRODAT values < 0.05. Conclusions Our study fits with the neuropathological and functional evidence that demonstrates the existence of nigrostriatal dysfunction in patients with ALS. Further research to better understand the role of these changes in the pathophysiological process of ALS needs to be performed.

Resumo Antecedentes A coexistência da esclerose lateral amiotrófica (ELA) com formas clínicas da doença de Parkinson (DP), embora incomum, é encontrada em um grau maior do que seria esperado ao acaso. Os mecanismos patológicos da ELA e da DP ainda não são totalmente compreendidos e a coexistência dessas duas doenças sugere que elas podem compartilhar mecanismos em comum. Objetivo Apresentamos uma amostra de pacientes com ELA clinicamente definida ou provável que foram avaliados com tomografia computadorizada por emissão de fóton único (SPECT)/TRODAT e comparados com controles sem ELA. Métodos Pacientes com ELA clinicamente definida ou provável foram avaliados com a escala funcional de esclerose lateral amiotrófica (ALSFRS) para definir a gravidade e foram coletados os seus dados demográficos. Os resultados do TRODAT de pacientes com ELA foram comparados com aqueles de pacientes com diagnóstico de DP com menos de 10 anos de duração e com pacientes com diagnóstico de outros distúrbios do movimento não associados a doenças neurodegenerativas. Resultados Um total de 75% dos pacientes com ELA apresentou resultados de TRODAT abaixo dos níveis considerados normais; 25% no grupo controle sem doença neurodegenerativa e 100% no grupo DP. Uma diferença estatisticamente significativa foi encontrada entre os pacientes com ELA e o grupo controle sem doença neurodegenerativa nos valores de TRODAT p< 0,05. Conclusões Nosso estudo está de acordo com as evidências neuropatológicas e funcionais que demonstram a existência de disfunção nigroestriatal em pacientes com ELA. Mais pesquisas para entender melhor o papel dessas mudanças no processo fisiopatológico da ELA precisam ser realizadas.

Resumo O tratamento da doença de Parkinson (DP) constitui um desafio, especialmente por ser considerado muito individualizado. A Academia Brasileira de Neurologia (ABN) identificou a necessidade de disseminar o conhecimento sobre o manejo do tratamento da DP, adaptando as melhores evidências à realidade brasileira. Assim, foi realizada uma revisão sobre as principais orientações de tratamento publicadas, baseada nas recomendações elaboradas por um grupo de especialistas em transtornos do movimento do departamento científico da ABN.

ABSTRACT The treatment of Parkinson's disease (PD) is challenging, especially since it is considered highly individualized. The Brazilian Academy of Neurology has recognized the need to disseminate knowledge about the management of PD treatment, adapting the best evidence to the Brazilian reality. Thus, the main published treatment guidelines were reviewed based on the recommendations of group from the Movement Disorders Scientific Department of the Brazilian Academy of Neurology.

Abstract Introduction Dysphagia is a relevant symptom in Parkinson disease (PD), and its pathophysiology is poorly understood. To date, researchers have not investigated the effects of combined motor tasks on swallowing. Such an assessment is of particular interest in PD, in which patients have specific difficulties while performing two movements simultaneously. Objective The present study tested the hypothesis that performing concurrent tasks could decrease the safety of swallowing in PD patients as visualized using fiberoptic endoscopic evaluation of swallowing (FEES). Methods A total of 19 patients and 19 controls matched by age, gender, and level of schooling were compared by FEES under two conditions: isolated swallowing and dual task (swallowing during non-sequential opposition of the thumb against the other fingers). The two tasks involved volumes of food of 3 mL and 5 mL. The PD subjects were classified according to the Hoehn & Yahr (H&Y) Scale, the Mini Mental State Examination (MMSE), and the Montreal Cognitive Assessment (MoCA). The FEES assessment was performed according to the Boston Residue and Clearance Scale (BRACS). Results The data showed a significant worsening of swallowing in the dual task assessment for both volumes (3 mL: p ≤ 0.001; 5 mL: p ≤ 0.001) in the PD group. A correlation between the MoCA and dual-task swallowing of 3 mL was also found. Conclusion These findings suggest that additional tasks involving manual motor movements result in swallowing impairment in patients with PD. Moreover, these data highlight the need to further evaluate such conditions during treatment and assessment of PD patients.

Abstract Introduction Subthalamic nucleus deep brain stimulation (STN-DBS) improvesmotor function in individuals with Parkinson disease (PD). The evidence about the effects of STN-DBS on the voice is still inconclusive. Objective To verify the effect of STN-DBS on the voice of Brazilian individuals with PD. Methods Sixteen participants were evaluated on the Unified Parkinson Disease Rating Scale-Part III, and by the measurement of the acoustic modifications in on and off conditions of stimulation. Results The motor symptoms showed significant improvement with STN-DBS on. Regarding the acoustic measures of the voice, only the maximum fundamental frequency (fhi) showed a statistical difference between on- and off-conditions, with reduction in off-condition. Conclusion Changes in computerized acoustic measures are more valuable when interpreted in conjunction with changes in other measures. The single finding in fhi suggests that DBS-STN increases vocal instability. The interpretation of this result should be done carefully, since it may not be of great value if other measures that also indicate instability are not significantly different.

ABSTRACT Purpose To develop a protocol for the evaluation of acquired speech disorders in individuals with Parkinson's disease (PADAF) and to validate its content and determine its inter-judge reliability. Methods The study was carried out in three stages: in the first one, the protocol was prepared and its content validated through the analysis of seven specialists; in the second, the instrument was applied to 25 individuals with idiopathic Parkinson's disease (PD); in the third and last stage, the inter-judge reliability was determined. Results The final version of PADAF consisted of 32 items that evaluated breathing, phonation, resonance, articulation, and prosody. It was shown to be valid, with a content validity index (CVI) much higher than that established in the literature, and with perfect agreement in the determination of inter-judge reliability. Conclusion PADAF for PD individuals was developed and its content was validated, showing perfect instrument reliability.

Abstract Introduction Deep brain stimulation (DBS) is an established treatment for Parkinson’s disease (PD). However, there is little evidence regarding the effect of DBS on dysphagia. Objective To assess the swallowing and quality of life of individuals with PD before and after DBS surgery. Methods Our sample consisted of people who had undergone DBS surgery in a referral hospital in the state of Rio Grande do Sul, Brazil. The inclusion criteria were a diagnosis of PD and having undergone DBS surgery. A cognitive screening, through a questionnaire about depression and quality of life, was conducted. Evaluations of each patient’s swallowing were performed before and after surgery. The assessment consisted of anamnesis, clinical assessment, the Functional Oral Intake Scale, clinical evaluation of swallowing, and the Hoehn and Yahr scale. Results The sample included 10 individuals, all male, with a mean age of 57.3 years (±4.7), a mean disease duration of 13.0 years (±2.4), and mean level education of 8.1 years (±4.0). In the clinical evaluation of the swallowing, a significant improvement after DBS was not observed. However, little changes in the signs and symptoms of dysphagia that had a positive impact on the quality of life were observed. Furthermore, there was no relation between the patients’ motor subtype and swallowing pre- and post-DBS. Conclusion There was an improvement in the quality of life of the patients after DBS. However, the improvement in the clinical signs and symptoms of dysphagia did not cause an overall improvement in the swallowing function.

RESUMO O Brasil é um país heterogêneo com dimensões continentais. As diferentes características culturais, do padrão socioeconômico e demográfico da população direcionam diferentes estratégias de atenção neurológica. Este conhecimento ajuda a entender o cenário atual para consequente preparação para os desafios futuros. Utilizamos informações dos relatórios anuais de Academia Brasileira de Neurologia (ABN) desde 2006, além de dados de uma pesquisa para os membros da ABNr ealizada em 2016. A distribuição geográfica dos membros da ABN no Brasil segue a concentração demográfica da população. A participação na pesquisa dos membros das grandes cidades foi a mais prevalente. 18,7% eram neurologistas jovens e 36,7% tinham mais de 20 anos de prática neurológica. O aperfeiçoamento do conhecimento da prática neurológica no Brasil será útil para a liderança da ABN planejar ações futuras. A ABN deve se esforçar para agregar um maior número de neurologistas, oferecendo constante atualização e apoio profissional contribuindo para políticas de saúde para disseminar o conceito de doenças neurológicas no Brasil.

ABSTRACT Brazil is a heterogeneous country with continental dimensions. The different characteristics of cultural, socioeconomic, and demographic status of the population drive different strategies for neurological care. This knowledge helps the understanding of the current scenario with the consequent possibility of preparing for future challenges. We used data from annual internal forms of the Brazilian Academy of Neurology (BAN) since 2006 and the survey for all BAN members (3,240) in 2016. The geographic distribution of BAN members in Brazil follows the demographic concentration of the population. Participation of members from big cities was the most prevalent, 18.7% of participants were young neurologists, and 36.7% of neurologists had more than of 20 years of neurological practice. The improvement of knowledge of neurological practice in Brazil will be useful for BAN leadership in planning future actions. The BAN must make an effort to aggregate a greater number of neurologists, offering updating support contributing to health policies to disseminate neurological care in Brazil.

RESUMO Objetivo O manejo da doença de Parkinson (DP) é usualmente alcançado com sucesso com o tratamento farmacológico apropriado. Entretanto, os pacientes com DP podem manifestar sintomas neuropsiquiátricos secundários à terapêutica, como a síndrome de descontrole dos impulsos (SDI), que se apresenta como o jogar patológico, a hipersexualidade, o comprar, beber ou comer compulsivos. Traduzimos e validamos a versão em português do questionário padrão-ouro para identificação de transtornos impulsivo-compulsivos na DP (QUIP-CS) para identificar nesses pacientes a presença de SDI. Métodos Foram realizadas a tradução, a retrotradução e a submissão do instrumento ao desenvolvedor deste, que aprovou a nova versão comparando esta à sua, que já está validada, sem a perda das suas propriedades originais. Após, a versão em português foi administrada a 30 pacientes com o diagnóstico de DP. Eles também foram solicitados a classificar o nível de compreensibilidade das questões, graduando-as de 1 a 5. Resultados O nível médio de compreensão foi 4,06 ± 0,69 DP, considerando-se 3 ou mais como aceitável. Nenhum paciente respondeu 1 ou 2. Conclusão Os nossos resultados para a versão em português da QUIP-CS mostraram que essa versão, traduzida e corrigida, foi facilmente compreendida e aplicada pelos próprios pacientes.

ABSTRACT Objective Parkinson’s disease (PD) management is usually successfully reached with proper pharmacological treatment. However, PD patients can manifest neuropsychiatric symptoms secondary to medical therapy, including impulse control disorders (ICD), presenting as pathological gambling, hypersexuality, compulsive buying, drinking or eating disorders. We translated and validated the Portuguese version of the gold-standard questionnaire Parkinson’s Disease Impulsive-Compulsive Disorders Questionnaire, or (QUIP) for identifying ICDs in PD patients. Methods Translation, back translation and submission to instrument developer was performed, that approved its new version comparing it to his original, validated version, with no loss of it’s original properties. Then, the Portuguese version was administered to 30 PD patients. They also were asked to rate from 1 to 5 the level of comprehensibility of the questions. Results The average level of comprehension was 4.06 ± 0.69 DP, considering 3 or more as acceptable. No patient has answered 1 or 2. Conclusion Our results on Portuguese version of QUIP-CS show that QUIP-CS translated and corrected version was easily understood and easily self-applied.

Abstract Introduction Dysphagia is a common symptom in Parkinson's disease (PD) and it has been associated with poor quality of life (QoL), anxiety, depression. Objective The aim of this study was to evaluate the quality of life in individuals with PD before and after SLP therapy. Methods The program consisted of four individual therapy sessions. Each session comprised guidelines regarding food and postural maneuvers (chin down). The Quality of Life in Swallowing Disorders (SWAL-QOL) questionnaire was applied before and after therapy. Results The sample comprised of 10 individuals (8men), with amean (SD) age of 62.2 (11.3) years, mean educational attainment of 7.5 (4.3) years, andmean disease duration of 10.7 (4.7) years. Thirty percent of patients were Hoehn and Yahr (H&Y) stage 2, 50% were H&Y stage 3, and 20% were H&Y stage 4. Mean scores for all SWAL-QOL domains increased after the intervention period, with significant pre- to post-therapy differences in total score (p = 0.033) and domain 4 (symptom frequency) (p = 0.025). There was also a bias significance for domain 5 (food selection) (p = 0.095). Conclusion Patients exhibited improvement in swallowing-related quality of life after a SLP therapy program. The earlier in the course of PD, greater the improvement observed after therapy.
