Multiple System Atrophy (MSA) is a progressive neurodegenerative disorder characterized by a combination of symptoms that affect both the autonomic nervous system (the part of the nervous system that controls involuntary action such as blood pressure or digestion) and movement. The symptoms reflect the progressive loss of function and death of different types of nerve cells in the brain and spinal cord.
MSA is a rare disease, affecting potentially 15,000 to 50,000 Americans, including men and women and all racial groups. Symptoms tend to appear in a person’s 50s and advance rapidly over the course of 5 to 10 years, with progressive loss of motor function and eventual confinement to bed. While some of the symptoms of MSA can be treated with medications, currently there are no drugs that are able to slow disease progression and there is no cure.
