Descriptive epidemiological study on patients with movement disorders, with emphasis on Parkinson's disease

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.

Síndrome da Paralisia Supranuclear Progressiva: As dificuldades de diagnóstico e a atuação da Equipe multidisciplinar quanto aos cuidados à pessoa afetada por esta doença / Progressive Supranuclear Palsy Syndrome: The difficulties of diagnosis and the performance of the Multidisciplinary Team regarding the care of the person affected by this disease / Síndrome de parálisis supranuclear progresiva: Las dificultades de diagnóstico y el trabajo del equipo multidisciplinario sobre el cuidado de la persona afectada por esta enfermedad

A Síndrome da Paralisia Supranuclear Progressiva (PSP) é doença neurodegenerativa do Sistema Nervoso Central (SNC), rara, e de difícil diagnóstico, afetando principalmente o tronco cerebral e os núcleos da base. O quadro clínico se caracteriza por oftalmoparesia supranuclear, instabilidade postural e demência. O objetivo do estudo foi investigar a fisiopatologia, diagnóstico, tratamento e assistência da equipe multidisciplinar às pessoas com PSP. Revisão integrativa de 15 artigos publicados na base de dados da Biblioteca Virtual da Saúde, BVS, envolvendo estudos de casos e pesquisa de campo. O estudo revelou pouca publicação acerca da doença e, por ser rara, não existe fármaco eficiente e eficaz; o diagnóstico é limitado nas primeiras manifestações, e somente possível por meio de exames mecanicistas. Em razão de existir parco material sobre a assistência a estes casos, sugere-se que os Conselhos, Associações de Neurologia e demais especialidades envolvidas no tratamento desenvolvam, divulguem mais detalhes sobre a doença, a fim de se criar um protocolo de atendimento integral aos afetados pela síndrome, bem como o necessário apoio aos familiares e cuidadores, que auxilie nas práticas da assistência ambulatorial e familiar.

Progressive Supranuclear Palsy Syndrome (PSP) is a rare and difficult diagnosis of the central nervous system (CNS) neurodegenerative disease that mainly affects the brainstem and nuclei of the base. The clinical picture is characterized by supranuclear ophthalmoparesis, postural instability and dementia. Objective: to investigate the pathophysiology, diagnosis, treatment and assistance of the multidisciplinary team to PSP users. Integrative review of 15 articles published in the database of the Virtual Health Library, VHL, involving case studies and field research. Results: the study revealed little publication about the disease and, because it is rare, there is no efficient and effective drug; The diagnosis is limited in the first manifestations, and it is only possible by means of mechanistic examinations. Because there is little material on the assistance to these cases, it is suggested that the Neurology Councils and Associations and other specificities involved in the treatment develop and disseminate more details about the disease, in order to create a protocol for comprehensive care Affected by this syndrome, as well as the necessary support for family members and caregivers, to assist in outpatient and family care practices.

Parálisis Supranuclear Progresiva Syndrome (PSP) es una enfermedad neurodegenerativa del sistema nervioso central (SNC), una rara y difícil de diagnosticar, que afecta principalmente el tronco cerebral y los ganglios basales. El cuadro clínico se caracteriza por oftalmoparesia supranuclear, inestabilidad postural y demencia. Investigar la fisiopatología, diagnóstico, tratamiento y atención del equipo multidisciplinario para llevar a la PSP. Revisión integradora de 15 artículos publicados en la Biblioteca Virtual en Salud Base de datos, BVS, que incluye casos de estudio y la investigación de campo. El estudio mostro poca publicación de la enfermedad y, debido a que es raro, no hay ningún fármaco eficaz y eficiente; el diagnóstico es limitada en las primeras manifestaciones, y sólo es posible a través de pruebas mecanicistas. Dado que el material que hay escasa la ayuda a estos casos, se sugiere que las juntas y asociaciones de neurología y otras especilidades implicados en el tratamiento desarrollan y dan a conocer más detalles acerca de la enfermedad, de manera que se crea un protocolo de tratamiento integral para afectadas por este síndrome, así como el apoyo necesario a las familias y cuidadores para ayudar en las prácticas de atención ambulatoria y la familia.

Liver transplantion in a patient with rapid onset parkinsonism-dementia complex induced by manganism secondary to liver failure

Bilateral and symmetric globus-pallidus hyperintensities are observed on T1-weighted MRI in most of the patients with chronic liver failure, due to manganese accumulation. We report a 53-year-old man, with rapid onset parkinsonism-dementia complex associated with accumulation of manganese in the brain, secondary to liver failure. A brain MRI was performed and a high signal on T1-weighted images was seen on globus-pallidus, as well as on T2-weighted images on the hemispheric white-matter. He was referred to a liver-transplantation. The patient passed away on the seventh postoperative day. Our findings support the concept of the toxic effects of manganese on the globus-pallidus. The treatment of this form of parkinsonism is controversial and liver-transplantation should not be considered as first line treatment but as an alternative one.

Hiperintesidades simétricas e bilaterais dos gânglios da base são observadas em imagens de ressonância magnética encefálica (RM) ponderadas em T1 na maioria dos pacientes com insuficiência hepática crônica devidas ao acúmulo de manganês. Nós relatamos o caso de um homem, com 53 anos de idade, com um complexo parkinsonismo-demência rapidamente progressivo associado com o acúmulo de manganês no cérebro, secundariamente a insuficiência hepática. Uma RM encefálica foi realizada e foram observadas imagens hiperintensas/hipersinal nas imagens ponderadas em T1 no globo pálido e, também, na substância branca dos hemisférios cerebrais ponderadas em T2. Devido à falta de resposta ao tratamento clinico optamos pelo transplante hepático. O paciente faleceu no 7° dia de PO. Nossos achados corroboram o conceito dos efeitos tóxicos do manganês nos gânglios da base/globo pálido. O tratamento desta forma de parkinsonismo é controverso e o transplante hepático não deverá ser considerada uma opção terapêutica de primeira linha, porém como um tratamento alternativo considerando-se os riscos-benefícios dessa escolha.
