The Multiple System Atrophy Coalition: A Call to Action
Multiple system atrophy (MSA), also known as Shy–Drager syndrome, is a rare neurodegenerative disorder characterized by tremors, slow movement, muscle rigidity, and postural instability due to dysfunction of the autonomic nervous system, and ataxia. This is caused by progressive degeneration of neurons in several parts of the brain including the substantia nigra, striatum, inferior olivary nucleus, and cerebellum.
