Expanding the spectrum of neuronal pathology in multiple system atrophy

Multiple system atrophy (MSA) is characterized clinically by parkinsonism, cerebellar dysfunction, and dysautonomia, and pathologically by glial cytoplasmic inclusions. Using pathological and clinical data from 35 patients, Cykowski et al. expand the spectrum of neuronal pathology in MSA and argue that neuronal inclusions have a key role in disease pathogenesis.See Halliday (doi:10.1093/brain/awv151) for a scientific commentary on this article.
