Atrofia multisistémica del tipo cerebelosa: implicaciones patológicas de la conectividad neuronal

Introducción. La atrofia multisistémica (MSA) es una enfermedad neurodegenerativa progresiva que afecta principal mente la materia blanca (WM, por su sigla en inglés). Este tipo de atrofia se caracteriza por ocasionar inclusiones cito plasmáticas gliales de la proteína alfa-sinucleína, además de dis...

description Introducción. La atrofia multisistémica (MSA) es una enfermedad neurodegenerativa progresiva que afecta principal mente la materia blanca (WM, por su sigla en inglés). Este tipo de atrofia se caracteriza por ocasionar inclusiones cito plasmáticas gliales de la proteína alfa-sinucleína, además de disminuir la integridad, la desmielinización y los cambios en los diámetros axonales de la WM (trastornos del movimiento). Objetivo. Evaluar los hallazgos patológicos de la conectividad encontrados en casos de atrofia multisistémica de tipo cerebelosa (MSA-C) y las posibles conexiones que estos muestran con las señales clínicas, la fisiopatología de la enfermedad, la imagenología y los blancos terapéuticos mediante una revisión sistemática de la literatura científica disponible. Métodos. Se realizó una búsqueda bibliográfica en las bases de datos PubMed, ResearchGate, Embase y Scopus con los siguientes términos claves: “Multiple system atrophy” AND “therapy” OR “diagnostic imagining” OR “physiopathology” OR epidemiology”. Se seleccionaron artículos, en español e inglés, publicados entre 1989 y 2022. Tras aplicar los criterios de inclusión y exclusión y eliminar duplicados, se seleccionaron 61 estudios que comparaban los temas objetivo del estudio. Resultados. La conectividad funcional disminuida en la red de control ejecutivo izquierdo (ECN), relacionada con los circuitos de los ganglios basales y el tálamo, ocasiona desconexión cerebelo-prefrontal y cerebelo-amigdaloide / parahipocampal, lo cual tiene manifestaciones neuro histopatológicas que están correlacionadas con ciertos hallazgos imagenológicos. Conclusión. Se evidenció que resultados de diversos estudios han permitido dar viabilidad a la comprensión de la conectividad nodal identificada y sus manifestaciones anatomo-patológicas y funcionales en el curso natural de la MSA-C.

La atrofia multisistémica (MSA) es una enfermedad neurodegenerativa progresiva que afecta principal mente la materia blanca (WM, por su sigla en inglés). Este tipo de atrofia se caracteriza por ocasionar inclusiones cito plasmáticas gliales de la proteína alfa-sinucleína, además de disminuir la integridad, la desmielinización y los cambios en los diámetros axonales de la WM (trastornos del movimiento). Objetivo. Evaluar los hallazgos patológicos de la conectividad encontrados en casos de atrofia multisistémica de tipo cerebelosa (MSA-C) y las posibles conexiones que estos muestran con las señales clínicas, la fisiopatología de la enfermedad, la imagenología y los blancos terapéuticos mediante una revisión sistemática de la literatura científica disponible. Métodos. Se realizó una búsqueda bibliográfica en las bases de datos PubMed, ResearchGate, Embase y Scopus con los siguientes términos claves: “Multiple system atrophy” AND “therapy” OR “diagnostic imagining” OR “physiopathology” OR epidemiology”. Se seleccionaron artículos, en español e inglés, publicados entre 1989 y 2022. Tras aplicar los criterios de inclusión y exclusión y eliminar duplicados, se seleccionaron 61 estudios que comparaban los temas objetivo del estudio. Resultados. La conectividad funcional disminuida en la red de control ejecutivo izquierdo (ECN), relacionada con los circuitos de los ganglios basales y el tálamo, ocasiona desconexión cerebelo-prefrontal y cerebelo-amigdaloide / parahipocampal, lo cual tiene manifestaciones neuro histopatológicas que están correlacionadas con ciertos hallazgos imagenológicos. Conclusión. Se evidenció que resultados de diversos estudios han permitido dar viabilidad a la comprensión de la conectividad nodal identificada y sus manifestaciones anatomo-patológicas y funcionales en el curso natural de la MSA-C.Médico CirujanoPregradoIntroduction. Multiple system atrophy (MSA) is a progressive neurodegenerative disease primarily affecting white matter (WM). This type of atrophy is characterized by causing glial cytoplasmic inclusions of the alpha-synuclein protein and decreasing the integrity, demyelination, and changes in the axonal diameter (movement disorders). Objective. To evaluate the pathological findings of connectivity found in cases of Multiple system atrophy-cerebellar subtype (MSA-C) and the possible connections that these show with clinical signs, the pathophysiology of the disease, imaging and therapeutic targets through a systematic review of the available scientific literature. Methods. A bibliographic search was carried out in the PubMed, ResearchGate, Embase, and Scopus databases with the following key terms: “Multiple system atrophy” AND “therapy” OR “diagnostic imagining” OR “physiopathology” OR “epidemiology.” Articles were selected in Spanish and English and published between 1989 and 2022. After applying the inclusion and exclusion criteria and eliminating duplicates, 61 studies were selected that compared the study’s target topics. Results. Decreased functional connectivity in the left executive control network (ECN), related to the circuits of the basal ganglia and thalamus, causes cerebellar-prefrontal and cerebellar-amygdaloid/parahippocampal disconnection, which has neuro histopathological manifestations that are correlated with specific imaging findings. Conclusion. It was evident that the results of various studies have made it possible to give viability to the understanding of the identified nodal connectivity and its anatomical-pathological and functional manifestations in the natural course of MSA-C.application/pdfAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Acceso abiertohttps://purl.org/coar/access_right/c_abf2http://purl.org/coar/access_right/c_abf2Atrofia de múltiples sistemasAlfa-sinucleínaAtaxia cerebelosaRed en modo predeterminadoImagen de difusión por resonancia magnéticaMulti-system atrophyAlpha-synucleinCerebellar ataxiaDefault mode networkDiffusion-weighted magnetic resonance imaging.W100Atrofia multisistémica del tipo cerebelosa: implicaciones patológicas de la conectividad neuronalMultiple system atrophy cerebellar variant: pathological implications of the neural connectivityMedicinaUniversidad El BosqueFacultad de MedicinaTesis/Trabajo de grado - Monografía - Pregradohttps://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/resource_type/c_7a1finfo:eu-repo/semantics/bachelorThesishttps://purl.org/coar/version/c_ab4af688f83e57aa1.
