Cerebrovascular pathology and misdiagnosis of multiple system atrophy: An autopsy study

摘要

Background: Multiple system atrophy (MSA) is a progressive neurodegenerative disease characterized by a combination of dysautonomia, parkinsonism, and cerebellar ataxia. Other disorders can mimic MSA, but it is unknown whether cerebrovascular pathology, so-called "vascular parkinsonism," can mimic MSA. This study aimed to determine the clinicopathological features and red flags for vascular parkinsonism masquerading as MSA.
