Multiple System Atrophy (MSA) is a rare brain disorder that until recently was largely ignored by the research community. MSA is a rapidly progressing neurodegenerative disease caused by a decline of the body’s most basic and vital functions including breathing, digestion, urination, controlling blood pressure and movement. It is not known how MSA arises, and no environmental or genetic contributors have been identified. Several mechanisms are believed to contribute to the disease process.
