ABSTRACT
Objetivos: Apresentar as características gerais da DH e os principais desafios encarados no cotidiano pelos portadores. Método: foi realizada uma revisão de literatura na qual foram considerados artigos científicos embasados em banco de dados (PubMed, Scielo, Lilacs e diretório Google Acadêmico), artigos entre anos de 2007 a 2022, publicados em todos os idiomas, e aplicados os seguintes descritores: Huntington's Disease Treatment; Genetics foram incluídos. Resultado: após a inclusão de 21 artigos utilizados, foi observado a significância de elevado índice mundial da DH, que acomete população em geral, porém há probabilidade que seja mais de herança paterna do que materna, devido à formação dos espermatozoides, principalmente quando se manifestam na fase juvenil de forma acelerada. Embora sejam desvendadas alternativas para terapia paliativa medicamentosa, há, também, a terapia física, o que auxilia a possibilidade de evolução na saúde desses indivíduos. Porém, prosseguem as pesquisas relacionadas às condutas melhores na qualidade de vida dessa população. Conclusão: Esta revisão evidencia a importância para doenças neurodegenerativas pouco vistas e comentadas, como a DH, mas que carece de esclarecimentos que auxiliem, com eficácia, tanto na recuperação, como no processo de habilidades da existência desses portadores com DH.
Objectives: to present the general characteristics of HD and the main challenges faced in daily life by patients. Method: a literature review was conducted in which scientific articles were considered based on databases (PubMed, Scielo, Lilacs, and Google Scholar directory), articles between 2007 and 2022, published in all languages, and the following descriptors were applied: Huntington's Disease Treatment; Genetics were included. Result: after the inclusion of 21 articles, it was observed the significance of the high worldwide HD index, which affects the general population, but there is a probability that it is more paternal than maternal inheritance due to sperm formation, especially when they manifest in the juvenile phase in an accelerated manner. Although alternatives for palliative drug therapy are unveiled, there is also physical therapy, which helps the possibility of evolution in the health of these individuals. However, the researches related to the best conducts in the quality of life of this population continue. Conclusion: this review highlights the importance of little-seen and commented neurodegenerative diseases, such as HD, but that lacks clarification that effectively assists, both in recovery and in the process of abilities of the existence of these patients with HD.

La Enfermedad de Huntington (EH), ha sido reconocida como una de las tres enfermedades neurodegenerativas de mayor impacto a nivel mundial, junto al Parkinson y al Alzheimer. El daño producido porla EH afecta principalmente zonas del Sistema Nervioso Central (SNC), como los ganglios basales y tiene una base genética, que es transmitida de generación en generación de manera autosómica dominante. El problema genético específico se localiza en un defecto del brazo corto del cromosoma 4, llamado IT15, que tiene repeticiones trinucleicas superiores a 38 duplicaciones. La EH puede manifestarse en etapa juvenil o en etapa adulta. El diagnóstico de la EH ha resultado en la mayoría de los casos tardío y aúnno se ha descubierto un método eficaz para tratar la enfermedad. La Calidad de Vida (CV) de los pacientes con EH tiende a degradarse a medida que evoluciona la enfermedad, y aún faltan más estudios clínicos interdisciplinarios que la traten con eficacia.
Huntingtons Disease (HD) has been recognized as one of the three neurodegenerative diseases with greatest impact around the world, beside Parkinsons disease and Alzheimer disease. The damage caused by HD primarily affects areas of the Central Nervous System (CNS), such as the basal ganglia and it a genetic basis, which is transmitted from generation to generation in an autosomal dominant manner. The specific genetic problem is located on the short arm of chromosome 4, called IT15, which has tri-nucleic repetitions above 38 duplications. HD can occur in youth or adulthood stage. The diagnosis of HD has resulted in many delayed cases and there has not yet been found an effective method of treating disease. The Quality of Life (QoL) of patients with HD tends to degrade as the disease progresses and there are still more interdisciplinary clinical studies to be treated effectively.

ABSTRACT Chorea is an abnormal movement characterized by a continuous flow of random muscle contractions. This phenomenon has several causes, such as infectious and degenerative processes. Chorea results from basal ganglia dysfunction. As the control of the eye movements is related to the basal ganglia, it is expected, therefore, that is altered in diseases related to chorea. Sydenham’s chorea, Huntington’s disease and neuroacanthocytosis are described in this review as basal ganglia illnesses that can present with abnormal eye movements. Ocular changes resulting from dysfunction of the basal ganglia are apparent in saccade tasks, slow pursuit, setting a target and anti-saccade tasks. The purpose of this article is to review the main characteristics of eye motion in these three forms of chorea.
RESUMO Coreia é um movimento anormal caracterizado pelo fluxo contínuo de contrações musculares ao acaso. Este fenômeno possui variadas causas, como processos infecciosos e degenerativos. A coreia resulta de disfunção dos núcleos da base, os quais estão envolvidos no controle da motricidade ocular. É esperado, então, que esta esteja alterada em doenças com coreia. A coreia de Sydenham, a doença de Huntington e a neuroacantocitose são apresentadas como modelos que têm por característica este distúrbio do movimento, por ocorrência de processos que acometem os núcleos da base. As alterações oculares decorrentes de disfunção dos núcleos da base se manifestam em tarefas de sacadas, perseguição lenta, fixação de um alvo e em tarefas de antissacadas. O objetivo deste artigo é revisar as principais características dos movimentos oculares nestas três formas de coreias.

The prevalence of neurodegenerative diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD), increases with age, and the number of affected patients is expected to increase worldwide in the next decades. Accurately understanding the etiopathogenic mechanisms of these diseases is a crucial step for developing disease-modifying drugs able to preclude their emergence or at least slow their progression. Animal models contribute to increase the knowledge on the pathophysiology of neurodegenerative diseases. These models reproduce different aspects of a given disease, as well as the histopathological lesions and its main symptoms. The purpose of this review is to present the main animal models for AD, PD, and Huntington's disease.

La palabra Corea se originó en la función del "coro" del teatro griego clásico, que incluía discurso, canto, música y danza. Dejó de usarse en la Edad Media y reapareció en el siglo XVII como calificativo de lo que "podría parecerse a un baile", en el sentido de ser un reiterado movimiento del cuerpo y miembros, en general grosero, contorsivo y saltarín, que se presentaba habitualmente en epidemias, que se conocen como de "manía danzante", seguramente histéricas. Si ocurría entonces algún caso de enfermedad Corea, como la que hoy conocemos, que hasta podría ser la desencadenante de la epidemia, quedaba sumergida en el conjunto y resultaba irreconocible. Del examen de la escasa iconografía de la época y de la música con que se pretendía curarla, no surge un patrón general que permita analizar los movimientos, para compararlos con la enfermedad Corea actual. Más aún, un análisis semiológico de varios casos actuales de Corea de Huntington no permite reconocerle condición de baile. Dada la época del apogeo de la popularidad de la Corea (o tarantismo) epidémicos, resulta probable que su calificación de baile y la pretensión de asignarle un correlato musical haya sido producto de la coyuntura cultural del barroco
