What is multiple system atrophy?

Multiple system atrophy (MSA) is a term used for a group of rare disorders that reduce the function of the nervous system over time. Its symptoms are similar to those of Parkinson's disease.

Parkinson-like symptoms of MSA include slow movement, stiff muscles, and loss of balance and coordination when walking. MSA also causes changes in posture, trouble swallowing and speaking, urination problems, and erectile dysfunction. MSA may cause a jerky tremor. Both MSA and Parkinson's disease can cause dizziness when standing up due to a drop in blood pressure. This can lead to falls.

There is no way to stop the nerve loss that occurs with MSA. But medicines can help relieve symptoms.
