Abstract
BACKGROUND Knowing the epidemiological profile is relevant for improving healthcare practices. Movement disorders are neurological disorders characterized by the presence of involuntary movements. They have a negative impact on patients' quality of life. OBJECTIVES To outline the frequencies of the different diagnoses seen among patients, along with their demographic characteristics, at a hospital in São Paulo (SP), Brazil, and to highlight the clinical aspects of those with Parkinson's disease. DESIGN AND SETTING Retrospective descriptive epidemiological analysis at a specialized outpatient clinic in a state public hospital in São Paulo. METHODS Patients treated at this clinic over a four-year period were analyzed. Diagnoses, demographic variables and associations with clinical aspects of Parkinson's disease were evaluated. RESULTS Out of the 680 medical records analyzed, 58.4% related to females. Most patients were over 60 years of age, white, married and teachers. The most frequent diagnosis was Parkinson's disease, followed by essential tremor and dystonia. Parkinson's disease presented in the mixed clinical form; the most common initial symptom was tremor. The akinetic-rigid clinical form occurred in younger individuals and mostly presented with postural instability and freezing of gait in the early years of disease. CONCLUSIONS Parkinson's disease, essential tremor and dystonia were the most frequent diagnoses. Characteristics like sex, frequency of other pathological conditions and the clinical and demographic aspects of Parkinson's disease were consistent with the data in the relevant literature.

Abstract
Abstract
Introduction
Cinnarizine (CNZ) and flunarizine (FNZ) belong to the calcium channel blockers class of medication.
Main text
The aim of this literature review is to evaluate the clinical epidemiological profile, pathological mechanisms, and management of CNZ/FNZ-associated movement disorder (MD). Relevant reports in six databases were identified and assessed by two reviewers without language restriction. One hundred and seventeen reports containing 1920 individuals who developed a CNZ/FNZ-associated MD were identified. The MD encountered were 1251 parkinsonism, 23 dyskinesias, 11 akathisia, 16 dystonia, and 5 myoclonus, and in the group not clearly defined, 592 extrapyramidal symptoms, 19 tremors, 2 bradykinesia, and 1 myokymia. The predominant sex was female with a percentage of 72.69% (466/641). The mean age was 74.49 (SD, 7.88) years. The mean CNZ dose was 148.19 mg (SD, 42.51) and for the FNZ dose, 11.22 mg (5.39). The mean MD onset and recovery were 1.83 years (SD, 1.35) and 3.71 months (SD, 1.26). In the subgroup of subjects that had improvement of the symptoms, the complete recovery was achieved within 6 months of the drug withdrawal in almost all subjects (99%). The most common management was drug withdrawal. A complete recovery was observed in 93.77% of the patients (437/466).
Conclusions
CNZ/FNZ-associated MD was extensively reported in the literature. Parkinsonism was the most well described. Myoclonus (MCL) was the poorest described MD with missing data about the neurological examination and electrodiagnostic studies. The knowledge of this disorder probably can contribute to the understanding of the other drug-induced MDs.

Abstract
Objective To report the clinical and neuroimaging findings in a case series of vascular parkinsonism (VP). Methods Seventeen patients with VP were evaluated with motor, cognitive, and neuroimaging standardized tests and scales. Results All patients had arterial hypertension. Ten patients were male and the mean age of the whole sample was 75.8±10.1 years. The mean age of parkinsonism onset was 72.2±10.0 years. Common clinical features were urinary incontinence (88.2%), lower limb parkinsonism with freezing of gait and falls (82.3%), and pyramidal signs (76.4%). The mean Unified Parkinson’s Disease Rating Scale (UPDRS) and Hoehn-Yahr scores were 72.5±21.6 points and 3.3±0.9 points, respectively. Sixteen (94.1%) patients had freezing of gait and executive dysfunction. Twelve (70.5%) patients had probable vascular dementia. The mean dose of levodopa was 530.9 mg/day. Unresponsiveness to the drug was confirmed by a 6.9 mean point reduction in the UPDRS score after the “practically defined off” test. Conclusion This series provides a profile of VP with predominant lower-limb involvement, freezing of gait and falls, pyramidal signs, executive dysfunction, concomitant vascular dementia, and poor levodopa response.

Abstract
OBJECTIVE Numerous ultrasound studies have suggested that a typical enlarged area of echogenicity in the substantia nigra (SN+) can help diagnose idiopathic Parkinson's disease (IPD). Almost all these studies were retrospective and involved patients with well-established diagnoses and long-disease duration. In this study the diagnostic accuracy of transcranial sonography (TCS) of the substantia nigra in the patient with an undiagnosed parkinsonian syndrome of recent onset has been evaluated. DESIGN Prospective cohort study for diagnostic accuracy. SETTING Neurology outpatient clinics of two teaching hospitals in the Netherlands. PATIENTS 196 consecutive patients, who were referred to two neurology outpatient clinics for analysis of clinically unclear parkinsonism. Within 2 weeks of inclusion all patients also underwent a TCS and a (123)I-ioflupane Single Photon Emission CT (FP-CIT SPECT) scan of the brain (n=176). OUTCOME MEASURES After 2 years, patients were re-examined by two movement disorder specialist neurologists for a final clinical diagnosis, that served as a surrogate gold standard for our study. RESULTS Temporal acoustic windows were insufficient in 45 of 241 patients (18.67%). The final clinical diagnosis was IPD in 102 (52.0%) patients. Twenty-four (12.3%) patients were diagnosed with atypical parkinsonisms (APS) of which 8 (4.0%) multisystem atrophy (MSA), 6 (3.1%) progressive supranuclear palsy (PSP), 6 (3.1%) Lewy body dementia and 4 (2%) corticobasal degeneration. Twenty-one (10.7%) patients had a diagnosis of vascular parkinsonism, 20 (10.2%) essential tremor, 7 (3.6%) drug-induced parkinsonism and 22 (11.2%) patients had no parkinsonism but an alternative diagnosis. The sensitivity of a SN+ for the diagnosis IPD was 0.40 (CI 0.30 to 0.50) and the specificity 0.61 (CI 0.52 to 0.70). Hereby the positive predictive value (PPV) was 0.53 and the negative predictive value (NPV) 0.48. The sensitivity and specificity of FP-CIT SPECT scans for diagnosing IPD was 0.88 (CI 0.1 to 0.95) and 0.68 (CI 0.58 to 0.76) with a PPV of 0.75 and an NPV of 0.84. CONCLUSIONS The diagnostic accuracy of TCS in early stage Parkinson's disease is not sufficient for routine clinical use. CLINICALTRIALS.GOV IDENTIFIER: NCT0036819.

Abstract
Vascular Parkinsonism (VP) is a form of secondary Parkinsonism resulting from
cerebrovascular disease. Estimates of the frequency of VP vary greatly
worldwide; 3% to 6% of all cases of Parkinsonism are found to have a vascular
etiology. In a Brazilian community-based study on Parkinsonism, 15.1% of all
cases were classified as VP, the third most common form, with a prevalence of
1.1% in an elderly cohort. Another Brazilian survey found a prevalence of 2.3%
of VP in the elderly. VP is usually the result of conventional vascular risk
factors, particularly hypertension, leading to strategic infarcts of subcortical
gray matter nuclei, diffuse white matter ischaemic lesions and less commonly,
large vessel infarcts. Patients with VP tend to be older and present with gait
difficulties, symmetrical predominant lower-body involvement, poor levodopa
responsiveness, postural instability, falls, cognitive impairment and dementia,
corticospinal findings, urinary incontinence and pseudobulbar palsy. This
article intends to provide physicians with an insight on the practical issues of
VP, a disease potentially confounded with vascular dementia, idiopathic
Parkinson's disease, dementia with Lewy bodies and other secondary causes of
Parkinsonism.

Abstract
OBJECTIVE To investigate the etiologic diagnoses of parkinsonism, underlining aspects of each form and comparing our findings with those published in a similar setting, 10 years before. METHODS A large cohort of 1528 patients with parkinsonism was analyzed, gathering data on demography, motor and non-motor characteristics, as well as the final etiologic diagnoses based on established criteria. RESULTS Parkinson's disease (PD) was the most common diagnosis representing 74.7%, followed by drug-induced parkinsonism (DIP) in 7.9%, vascular parkinsonism (VP) in 3.9%, other neurodegenerative disorders in 10%, and rare sporadic causes, divided as genetic, infectious and others, that summed 3.5%. Comparative analysis of these groups showed that each has particularities that extend beyond their diagnostic criteria. CONCLUSIONS The main conclusions are that the most important causes of parkinsonism in this setting are typical, with PD been the most common diagnosis, although other causes were frequent, encompassing one fourth of all cases. Although DIP was identified in a particularly large part of this cohort, this proportion is smaller than demonstrated previously in a Brazilian study conducted in the 90s. This decrease probably reflects higher awareness regarding the risk of this motor complication and the more widely used newer antipsychotics.

Abstract
The aim of the study was to evaluate the frequency and to perform phenotypic and genotypic characterization of familial Parkinsonism and early onset Parkinson's disease (EOPD) in a Brazilian movement disorder unit. We performed a standardized clinical assessment of patients followed by sequencing of PRKN, PINK1 in EOPD cases and SNCA, LRRK2 in familial Parkinsonism individuals. During the period of study (January through December, 2006), we examined 575 consecutive patients of whom 226 (39.3%) met the diagnosis of Parkinsonism and idiopathic Parkinson's disease (IPD) was diagnosed in 202 of the latter. Of the IPD cases, 45 (22.3%) had EOPD. The age at onset in the EOPD cases (n = 45) was 34.8 +/- 5.4 years (mean +/- standard deviation). The age at onset in the familial late-onset PD patients (n = 8) was 52.3 +/- 12.2 years. In the early onset cases, we identified five known mutations in PRKN, two single heterozygous and three compound heterozygous (P153R, T240M, 255Adel, W54R, V3I); in addition, we identified one novel mutation in PINK1 (homozygous deletion of exon 7). In the familial cases (late onset), 1 patient had a novel LRRK2 variant, Q923H, but no SNCA mutations were identified. We have demonstrated that EOPD accounts for a high frequency of IPD cases in our tertiary referral center. PRKN was the most commonly mutated gene, but we also identified a novel mutation in PINK1 and a novel variant in LRRK2.

Abstract
OBJETIVO: investigar as diferenças entre os achados eletromiográficos dos músculos supra-hióideos direito e esquerdo durante a deglutição de um líquido e um pastoso fino, em sujeitos idosos com doença de Parkinson e idosos sem doença neurológica. MÉTODOS: 30 sujeitos de ambos os sexos participaram deste estudo, 15 idosos sem doença neurológica e os demais com doença de Parkinson. Todos foram submetidos a um protocolo de avaliação clínica e avaliação eletromiográfica de superfície. RESULTADOS: foram constatadas diferenças significantes nos valores entre os sujeitos (f=14.4 e p= 0.000) e entre os lados (f=4.4 e p=0.0037). Em relação ao tempo de duração da contração muscular durante a deglutição as diferenças foram significantes apenas entre as consistências (f=8.2 e p=0.005). CONCLUSÃO: a amplitude eletromiográfica foi menor nos sujeitos com doença de Parkinson e maior nos músculos supra-hiódeos do lado direito em ambos os grupos. A duração da contração muscular não diferiu significativamente entre os sujeitos com doença de Parkinson e idosos sem doença neurológica e foi menor para a consistência líquida.

Abstract
BACKGROUND: The association between Dystonia and Parkinson's disease (PD) has been well described especially for foot and hand dystonia. There is however few data on dystonic postures in patients with atypical parkinsonism. OBJECTIVE: To evaluate the frequency and pattern of dystonia in a group of patients with atypical parkinsonism (multiple system atrophy - MSA, progressive supranuclear palsy - PSP, and corticobasal degeneration - CBD) and to investigate whether dystonia could be the first presenting symptom at disease onset in those patients. METHOD: A total of 38 medical charts were reviewed (n=23/MSA group; n=7/CBD group; n=8/PSP group) and data values were described as means/standard deviations. The variables evaluated were sex, age at onset, disease duration, first symptom, clinical features of dystonia and other neurological signs, response to levodopatherapy, Hoehn&Yahr scale >3 after three years of disease, and magnetic resonance imaging findings. RESULTS: The overall frequency of dystonia in our sample was 50% with 30.4% (n=7) in the MSA group, 62.5% (n=5) in the PSP group, and 100% (n=8) in the CBD group. In none of these patients, dystonia was the first complaint. Several types of dystonia were found: camptocormia, retrocollis, anterocollis, blepharoespasm, oromandibular, and foot/hand dystonia. CONCLUSION: In our series, dystonia was a common feature in atypical parkinsonism (overall frequency of 50%) and it was part of the natural history although not the first symptom at disease onset. Neuroimaging abnormalities are not necessarily related to focal dystonia, and levodopa therapy did not influence the pattern of dystonia in our group of patients.

Abstract
BACKGROUND: Impairment in non-motor functions such as disturbances of some executive functions are also common events in Parkinson's disease patients. OBJECTIVE: To verify the performance of Parkinson's disease patients in activities requiring visuoconstructive and visuospatial skills. METHOD: Thirty elderly patients with mild or moderate stages of Parkinson's disease were studied. The assessment of the clinical condition was based on the unified Parkinson's disease rating scale (56.28; SD=33.48), Hoehn and Yahr (2.2; SD=0.83), Schwab and England (78.93%), clock drawing test (7.36; SD=2.51), and mini-mental state examination (26.48; SD=10.11). Pearson's correlation and stepwise multiple regression were used for statistical analyses. RESULTS: The patients presented deterioration in visuospatial and visuoconstructive skills. CONCLUSION: The clock drawing test proved to be a useful predictive tool for identifying early cognitive impairment in thesbe individuals.

Abstract
The authors review some particularities of movement disorders (MDs) in the ethnically diverse population of Latin America. Although idiopathic diseases are evenly prevalent, access to treatment encounters difficulties that are worth discussing. Infectious-parasitic diseases observed throughout the continent occasionally present as MDs, and will be individually reviewed. Inherited MDs with regional foci of increased prevalence, particularly spinocerebellar ataxias, will also be considered. Whereas there is no treatment for genetic disorders, most of the other conditions are preventable or amenable to adequate treatment. Hope for better health standards for the Latin American population lies in profound social and political changes that are still to come.

Abstract
Several community-based surveys on the prevalence of Parkinsonism and Parkinson's disease have been conducted worldwide, with variations on their methodology and results. The objective of this study is to assess the prevalence of Parkinsonism and its causes in a cohort of individuals age 64 years or older in Bambuí, a Brazilian town. In phase I, 1,186 people older than 64 years responded to a 9-question screening questionnaire for Parkinsonism. In phase II, all subjects who scored > or = 2 points on the test were examined independently by at least 2 movement disorder-trained physicians. A movement disorder senior specialist excluded or confirmed the diagnosis in all suspected cases. The response rate was high for both phases (96% for phase I and 94% for phase II). The prevalence rate per 100 population over 64 years of age in this group was 7.2% for Parkinsonism of all types (n = 86). The most frequent causes were idiopathic Parkinson's disease and drug-induced Parkinsonism, with prevalence rates of 3.3% (n = 39) and 2.7% (n = 32), respectively. The prevalence of vascular Parkinsonism was 1.1% (n = 13). We found 1 case of posttraumatic Parkinsonism and another with multiple system atrophy. In this first population-based study of Parkinsonism conducted in Brazil, the prevalence in a cohort of elderly subjects was higher than the observed in other populations worldwide, especially because of the high rates of drug-induced and vascular Parkinsonism. The prevalence of Parkinson's disease was similar to that observed in elderly people in door-to-door surveys in other American, European, and Eastern countries.

Abstract
The purpose of this study is to determine the prevalence and the patterns of movement disorders (MD) in outpatients submitted to the chronic use of cinnarizine (cz) or flunarizine (fz), and to establish the main risk factors for MD development. Over a period of 3 months, data were collected from outpatients who were chronic users of cz or fz in a municipal health institute. A total of 26 outpatients were included and all of them were submitted to a protocol that included DSM-4 diagnosis criteria for drug-induced movement disorders, parkinsonism (PK) and depression. Parkinsonism was diagnosed in 34% of the patients, PK plus akathisia, PK plus akathisia and bucco-linguo-masticatory syndrome (BLMS), isolated BLMS and dystonia were found in 4% patients each. Patients with BLMS had the highest median age and the longest average period in which they used the drugs. The affected group, when compared to the non-affected one, presented with higher rates of depression. This study demonstrates the existence of a direct relationship between the time of use of cz and fz, the age and the prevalence of PK and other MD. It also suggests that these drugs increase the incidence of depression.

Abstract
PURPOSE OF REVIEW Vascular parkinsonism is a highly controversial concept since its first description by Critchley in 1929. There is no doubt that cerebrovascular disease can cause elements of parkinsonism. However, the extent of the spectrum of vascular parkinsonism remains quite imprecise. Here we review recent epidemiological, clinical, electrophysiological, morphological and functional brain imaging and pathological studies on 'vascular parkinsonism'. RECENT FINDINGS Epidemiological studies have demonstrated that vascular parkinsonism represents 3-5% of all cases of parkinsonism. The more specific clinical features are a history of stroke, lower body parkinsonism and poor levodopa response. Vascular risk factors are dominated by arterial hypertension, whereas others have been less evaluated. Vascular lesions within or outside the basal ganglia, unique and multiple, lacunae or territorial infarcts can be demonstrated by magnetic resonance imaging. Functional imaging of the dopaminergic pathway helps to differentiate vascular parkinsonism from idiopathic Parkinson's disease. However, none of these clinical or imaging criteria taken alone are specific for the diagnosis. A combination of convergent clinical and imaging clues are therefore necessary to improve the accuracy of the diagnosis, which is only certain when the pathology excludes underlying idiopathic Parkinson's disease. SUMMARY At present it remains unexplained why some patients develop vascular parkinsonism and others do not with the same apparent vascular lesion load. This will need further research along with the need to develop criteria to improve the accuracy of diagnosis of vascular parkinsonism. Vascular parkinsonism is also a research field on the relationships between vascular brain lesions and neurodegenerative disorders.

Abstract
BACKGROUND Drug-Induced Parkinsonism (DIP) represents the second leading cause of Parkinsonism (PK) in several countries. Flunarizine and cinnarizine are some of the most common drugs that cause DIP. This paper reviews the first description of Flunarizine and Cinnarizine-Induced Parkinsonism (FCIP), as well as the subsequent literature, emphasizing epidemiological, clinical and diagnostic aspects. METHODS We reviewed the literature on the subject, with special emphasis on the first description and the later definition of the clinical syndrome that results from chronic use of flunarizine and cinnarizine. RESULTS In 1984, De Melo-Souza reported the first description of flunarizine-induced PK in five patients. Other reports followed on FCIP, emphasizing the clinical features, which are symmetrical parkinsonism, and depression, affecting mainly elderly women. CONCLUSIONS Eighteen years after the original description, FCIP is a recognized condition with specific clinical features, and is the second most common cause of parkinsonism in many countries.

Abstract
INTRODUCTION Population aging in Brazil has increased the prevalence of neurodegenerative diseases (Parkinson's and Alzheimer's disease) and affective disorders (anxiety, depression), all common in old age. A retrospective study was carried out with the purpose of ascertaining if there is an association between falls and psychoactive medication use among older residents of a community in Brazil. METHODS All residents aged 65+ (n=161) of one neighborhood of Campo Belo, Brazil (population of 48,000) were evaluated regarding the use of psychoactive drugs and the occurrence of falls in the 12 months preceding the study. Vision and hearing screenings were also performed. RESULTS From the study population, 9.3% were taking prolonged half-life benzodiazepines, 4.4% anticonvulsants (mostly barbiturates), 2.5% antidepressants (all cyclics) and 8.1% alpha-methyldopa. No subject reported use of hypnotics, neuroleptics or drugs to treat Alzheimer's or Parkinson's diseases (except biperiden). As a whole, drugs that increase the risk of falls were used by 1/5 of this population. In the 12-month period preceding the study, 27 residents (16.8%) experienced falls and, of those, 4 (14.8%) had fracture(s). There was an independent association between psychoactive drug use and falls when variables such as age, gender, vision and hearing were controlled (p=0.02). CONCLUSIONS Although the population of this neighborhood must be considered young (only 4% are 65 years old or more), there are already problems related to the use of psychoactive drugs among people. Prescribed anxiolytics, anticonvulsants, antidepressants and antihypertensives are not appropriate for this age group and their use is associated with falls.
