Progression of speech disorder in multiple system atrophy
Multiple system atrophy(MSA)is a progressive neurodegenerative disease characterized by a variety of combinations of autonomic failure,Parkinson's disease,and cerebellar ataxia.In 2022,the Movement Disorders Society updated the diagnostic criteria for MSA,which states that"severe speech impairment within 3 years of motor onset"is one of the supportive motor features,suggesting that speech impairment might be an underlying clinical marker.This paper reviews the research progress of the speech disorders in MSA.
