Multiple System Atrophy
摘要
Informative Abstract: Multiple system atrophy (MSA) is an adult-onset, sporadic, and rapidly progressive neurodegenerative disorder, that currently lacks a cure. It manifests with a combination of symptoms such as parkinsonism, dysfunction of the autonomic system, impairment of the cerebellum, involvement of the pyramidal tract, and a poor response to medications targeting dopamine. The pathological features of MSA include the loss of cells, gliosis, and the presence of abnormal α-synuclein protein aggregates in oligodendroglia in various structures of the central nervous system. Clinically, MSA can be classified into two phenotypes based on the primary motor system affected: the parkinsonian variant (MSA-P) and the cerebellar variant (MSA-C). The diagnosis of MSA primarily relies on a thorough medical history and a meticulous neurological examination. Symptomatic treatment targeting various clinical manifestations and providing palliative care during the advanced stages of MSA form the cornerstone of current treatment strategies.
