These are:
* MSA with predominant parkinsonism (MSA-P) - defined as MSA where [[Extrapyramidal symptoms|extrapyramidal features]] predominate. It is sometimes termed striatonigral degeneration, a parkinsonian variant.{{citation needed|date=December 2020}}
* MSA with cerebellar features (MSA-C) -  defined as MSA in which cerebellar ataxia predominates.  It is sometimes termed sporadic olivopontocerebellar atrophy.{{citation needed|date=December 2020}}
