Despite active fundamental, translational and clinical research, no therapeutic
intervention has yet shown convincing effects on disease progression in
Parkinson’s disease (PD) patients. Indeed, several disease-modification trials
failed or proved to be inconclusive due to lack of consistency between clinical
rating scales and putative surrogate markers of disease progression, or
confounding symptomatic effects of the tested compound. Multiple system atrophy
(MSA) is a rapidly progressing orphan disorder leading to severe motor disability
within a few years. Together with PD and dementia with Lewy bodies (DLB), MSA
belongs to the synucleinopathies, a group of neurodegenerative disorders
characterized by the abnormal accumulation of alpha-synuclein. Crucial milestones
have been reached for successfully conducting clinical intervention trials in a
large number of patients with MSA. In this personal view, we will review
evidence, and discuss why MSA could prove the most relevant clinical model for
assessing treatments that target mechanisms operating in all synucleinopathies.
