RESUMEN
INTRODUCTION: With the current demographic transition, it is estimated that by 2050 Brazil will have a population of 90 million people aged 60 years or more, and in parallel Parkinson's disease (PD) will bring a considerable economic burden to our society. Brazil is considered multiracial due to its colonization, generating important social and regional inequalities. Knowing the costs of the PD may aid to improve local public policies. However, in Brazil, no estimates of these values have been made so far. OBJECTIVES: To evaluate direct, indirect, and out-of-pocket costs in Brazilian people with PD (PwP). METHODS: Categorical and numerical data were collected through a customized and standardized cost-related-questionnaire from 1055 PwP nationwide, from 10 tertiary movement disorders centers across all Brazilian regions. RESULTS: The estimated average annual cost of PwP was US$ 4020.48. Direct and indirect costs accounted for 63% and 36% of the total, respectively, and out-of-pocket costs were 49%. There were no evidence of differences in the total cost of PD across the regions of the country; however, differences were reported between the stages of the Hoehn and Yahr scale (H&Y). CONCLUSION: This data suggests a considerable burden of PD for Brazilian society in general, not only for the public health system, but mainly for those with PD.

The spectrum of neuropsychiatric phenomena observed in amyotrophic lateral sclerosis (ALS) is wide and not fully understood. Disorders of laughter and crying stand among the most common manifestations. The aim of this study is to report the results of an educational consensus organized by the Brazilian Academy of Neurology to evaluate the definitions, phenomenology, diagnosis, and management of the disorders of laughter and crying in ALS patients. Twelve members of the Brazilian Academy of Neurology - considered to be experts in the field - were recruited to answer 12 questions about the subject. After exchanging revisions, a first draft was prepared. A face-to-face meeting was held in Fortaleza, Brazil on 9.23.22 to discuss it. The revised version was subsequently emailed to all members of the ALS Scientific Department from the Brazilian Academy of Neurology and the final revised version submitted for publication. The prevalence of pseudobulbar affect/pathological laughter and crying (PBA/PLC) in ALS patients from 15 combined studies and 3906 patients was 27.4% (N = 1070), ranging from 11.4% to 71%. Bulbar onset is a risk factor but there are limited studies evaluating the differences in prevalence among the different motor neuron diseases subtypes, including patients with and without frontotemporal dementia. Antidepressants and a combination of dextromethorphan and quinidine (not available in Brazil) are possible therapeutic options. This group of panelists acknowledge the multiple gaps in the current literature and reinforces the need for further studies.

RESUMEN
OBJECTIVE: Multiple sclerosis (MS) prevalence, in some cities in Brazil, was estimated and was found to range from 0.75 to 30.7/100,000. The reasons for such a large variation in rates of prevalence are not clear, but environment and genetics help to explain this phenomenon. METHODS: A cross-sectional study using three sources of case ascertainment to estimate the prevalence of MS in the city of Goiânia in December, 2015. RESULTS: A total of 318 MS patients was found after removing overlapping sources. The prevalence of MS was 22.4/100,000 population. CONCLUSION: Our study was the first in Goiás and the third in the midwest region, and we found a great increase in the prevalence of MS in the region. It is necessary to perform other studies using the same methodology for a more accurate evaluation of the true prevalence of MS in Brazil.

RESUMO A prevalência de esclerose múltipla (EM) no Brasil foi estimada em algumas cidades e foi encontrada entre 0,75 e 30,7 / 100.000. As razões para tal grande variação nas taxas de prevalência não são claras, mas existem aspectos ambientais e genéticos para explicar esse fenômeno. Métodos: Foram utilizadas três fontes de averiguação de casos para estimar a prevalência de esclerose múltipla (EM) no município de Goiânia em dezembro de 2015. Resultados: Foram encontrados 318 casos de EM, retirando as sobreposições de fontes. A prevalência foi de 22,4 / 100.000. Conclusão: Nosso estudo foi o primeiro em Goiás e o terceiro na Região Centro-Oeste, e encontrou um grande aumento na prevalência de EM na região. É necessário realizar outros estudos utilizando a mesma metodologia para uma melhor avaliação da real prevalência da EM no Brasil.

Parkinson's disease (PD) is an age-related neurodegenerative disease characterized by loss of dopaminergic neurons associated with neuroinflammation. Toll-like receptors (TLRs) are expressed in peripheral blood leukocytes and also in neurons and glial cells mediating inflammation. This study aimed to investigate the peripheral blood leukocyte response to TLR2 and TLR4 agonists in young and elderly PD patients. Two groups of patients with PD were evaluated (≤ 55 years old and ≥ 65 years old), age-matched with healthy controls (n = 26). Severity of PD was evaluated by Unified Parkinson's Disease Rating Scale (UPDRS). Whole blood cultures were stimulated with lipopolysaccharide (LPS), a TLR4 agonist or Pam3Cys (Pam), a TLR2 agonist. Tumor necrosis factor alpha (TNFα) and interleukin 10 (IL-10) were measured by immunoenzimatic assay. 6 h-TNFα production was increased after TLR4 stimulation, mainly in young PD patients, whereas TLR2-induced TNFα and IL-10 levels were decreased in PD patients independent of age (p < 0.05). A reverse correlation between LPS-induced TNFα production and age was observed in PD patients and controls, but TNFα induced by TLR2 agonist was not associated with age of PD patients or controls. TNFα production induced by TLR4 but not by TLR2 was reversely associated with the age at PD onset and disease duration. No associations between UPDRS scores and cytokine levels were detected. In conclusion, TLR4 and TLR2 responses seem to be differentially affected during PD. Data suggest that TLR2 deficiency in periphery is independent of age of the patients, age at PD onset, or PD duration.

Botulinum toxin injections are the most effective approach for the treatment of focal dystonia. Despite growing demand and clinical indications over the years, there are few reports or publications of its use and benefit to patients seen at the Sistema Único de Saúde - SUS (Unified Health System). Analyzing the Datasus data (Unified Health System Information Department of Brazilian Ministry of Health), it was noticed that in Brazil the percentage of dystonic patient benefited from this procedure is still low. We therefore suggest some strategies to increase the dispensation of the toxin by the Brazilian Unified Health system for the dystonic patients.
RESUMEN
Esse texto apresenta as recomendações da Academia Brasileira de Neurologia (ABN), por intermédio do seu Departamento Científico de Neurologia Cognitiva e do Envelhecimento (DCNCE), para o tratamento da doença de Alzheimer no Brasil. Trata-se de uma revisão ampliada das recomendações publicadas em 2005. Os autores realizaram uma busca de artigos publicados a partir de 2005 nas bases MEDLINE (PubMed), LILACS e Cochrane Library. Os estudos foram categorizados em quatro classes e as evidências em quatro níveis, com base nas recomendações da Academia Americana de Neurologia publicadas em 2008. As recomendações terapêuticas referem-se à fase demencial da doença de Alzheimer. Apresentam-se recomendações para: farmacoterapia dos transtornos cognitivos, incluindo inibidores da acetilcolinesterase (IAChE), memantina e outros fármacos e substâncias; farmacoterapia dos sintomas comportamentais e psicológicos (SCPD), incluindo antipsicóticos, benzodiazepínicos, antidepressivos, anticonvulsivantes, IAChE, memantina e outros fármacos e substâncias; e tratamento não farmacológico dos transtornos cognitivos e dos SCPD.

Este artigo contém as conclusões de reunião de 17-18 de novembro de 2006 do Grupo Brasileiro de Estudo em Síndrome das Pernas Inquietas (GBE-SPI) sobre diagnóstico e tratamento de SPI. Reiterou-se que se trata de condição de diagnóstico exclusivamente clínico, caracterizada por sensação anormal localizada, sobretudo, mas não exclusivamente, em membros inferiores, com piora noturna e alívio por movimentação da parte envolvida. Agentes terapêuticos com eficácia comprovada por estudos classe I são agonistas dopaminérgicos, levodopa e gabapentina enquanto que ácido valpróico de liberação lenta, clonazepam, oxicodona e reposição de ferro têm eficácia sugerida por estudos classe II. As recomendações do GBE-SPI para manejo de SPI primária são medidas de higiene do sono, suspensão de agentes agravantes de SPI, tratamento de comorbidades e agentes farmacológicos. Para estes as drogas de primeira escolha são agentes dopaminérgicos; segunda escolha são gabapentina ou oxicodona; e terceira escolha são clonazepam ou ácido valpróico de liberação lenta.
This article contains the conclusions of the November 17-18, 2006 meeting of the Brazilian Study Group of Restless Legs Syndrome (GBE-SPI) about diagnosis and management of restless legs syndrome (RLS). RLS is characterized by abnormal sensations mostly but not exclusively in the legs which worsen in the evening and are improved by motion of the affected body part. Its diagnosis is solely based on clinical findings. Therapeutic agents with efficacy supported by Class I studies are dopamine agonists, levodopa and gabapentine. Class II studies support the use of slow release valproic acid, clonazepan and oxycodone. The GBE-SPI recommendations for management of SPI are sleep hygiene, withdrawal of medications capable of worsening the condition, treatment of comorbidities and pharmacological agents. The first choice agents are dopaminergic drugs, second choice are gabapentine or oxycodone, and the third choice are clonazepan or slow release valproic acid.

The present study, the largest in the literature, was performed to assess the effectiveness and safety of unilateral subthalamic nucleus (STN) lesioning for Parkinson's disease (PD). From August 1999 to September 2000, 21 consecutive patients evaluated pre- and postoperatively by a single examiner were operated. Levodopa intake and dyskinesia, Hoehn & Yahr, Schwab & England and UPDRS motor scores were recorded. Stereotactic CT and MRI and the effects of macrostimulation were used to determine STN coordinates. A single radiofrequency lesion was made (60-75ºC/60"). Concomitant ipsilateral Vim/VOp lesions were made in 8 patients. Using a new technique, we were able to determine the territory of STN involved by the surgical lesion. The Wilcoxon and Mann-Whitney statistical tests were applied to evaluate the surgical results. All recorded parameters showed stable improvement after a mean follow up of 13.5 months. Recurrence occurred in two patients. Contralateral tremor arrest and decrease of rigidity and bradykinesia should be regarded as STN hallmarks to stimulation. Hyperintense lesions in the early-phase MRI seem to be a poor prognostic factor. Lateral territory lesioning correlates with better results. There was no significant difference between the cohorts with and without a Vim/VOp lesion. Dyskinesias happened in two patients (promptly abolished by a Vim/VOp lesion). Other complications were transient and/or rare. In conclusion, STN lesioning is a safe and very effective procedure to treat PD and probably an underutilized operation for those who can not afford the costs of DBS

A toxina botulínica (TOXBA) produz paralisia muscularpela inibiçäo pré-sináptica da liberaçäo da acetilcolina. A eliminaçäo de sua toxicidade natural através de sofisticadas técnicas laboratoriais tornou possível clínica no tratamento de uma diversidade de desordens de movimentos até entäo de difícil controle. A filosofia de seu uso repousa na identificaçäo dos principais músculos envolvidos no movimento anormal e na paralisaçäo dos mesmos pela injeçäo tópica de TOXBA, de modo a bloquear o movimento anormal em questäo. O procedimento, em mäos experimentadas, é até simples e tem a vantagem de ser um método poco invasivo e de poder ser realizado ambulatorialmente. Além de seguro, tem elevada eficácia. A experiência pessoal do autor e a literatura mostram que melhora significativa é obtidaem estrabismo, 85 por cento; blefaroespasmo, 70-90 por cento; distonia oromadibular, 70 por cento; distonia cervical (torcicolo espasmódico), 50-90 por cento; distonia laríngea, 80-100 por cento; distonia de mäo, 40-80 por cento; e espasmo hemifacial, 90 por cento...
