What is multiple system atrophy?

Multiple system atrophy (MSA) is a rare, progressive neurological condition that affects the brain, interfering with how your brain communicates with the rest of your body. MSA also impacts the autonomic nervous system, which controls automatic bodily functions such as blood pressure regulation, digestion and urinary function.

Over time, MSA causes nerve cells in parts of the brain and spinal cord to break down and stop working. This leads to a range of symptoms that worsen over time.

MSA primarily affects two major systems in the body:

  • The central nervous system, which controls muscle movement, coordination and balance
  • The autonomic nervous system, which manages automatic functions like blood pressure, digestion, bladder control and breathing

Symptoms usually begin between the ages of 50 and 60, but the condition very rarely can develop in adults as young as 30. As the disease progresses, daily activities like walking, speaking and swallowing become increasingly difficult.

While there is no cure for MSA, treatments are available to help manage symptoms and improve quality of life. Early diagnosis and supportive care can make a meaningful difference.

Frequently asked questions

Multiple system atrophy symptoms

Multiple system atrophy (MSA) affects many different parts of the body. Symptoms usually appear in adulthood, typically between the ages of 50 and 60. The exact symptoms vary depending on the type of MSA, and they can worsen over time as the disease progresses.

There are two main types of MSA: parkinsonian and cerebellar. The type is determined by the specific symptoms that are most noticeable at the time of diagnosis.

Multiple system atrophy causes

Experts don’t know exactly what causes multiple system atrophy, but they believe it’s connected to a protein called α-synuclein (alpha-synuclein) that can build up in different parts of the brain. This same protein is thought to play a role in the development of Parkinson’s disease.

Proteins are important for how your body works. They help different body systems communicate with each other, carry chemical compounds throughout the body, and more. But when proteins become damaged and build up in the wrong areas, they can become unhealthy and can lead cells to stop functioning properly. Experts believe this damage leads to the progressive breakdown of brain tissue in MSA.

Scientists are still trying to figure out why α-synuclein builds up in certain areas of the brain. They think it could be linked to genetic mutations that affect how some cells use this protein. There’s also some evidence that MSA-C may run in families. However, researchers haven’t found any strong genetic connection with MSA-P yet.

How is multiple system atrophy diagnosed?

Diagnosing multiple system atrophy can be challenging because its symptoms often look like other neurological conditions, especially Parkinson’s disease. There is no single test that can confirm MSA, so doctors use a combination of tools to evaluate symptoms, rule out other conditions and monitor how the disease progresses over time.

If your primary care provider suspects MSA, they may refer you to a neurologist for further evaluation. A detailed medical history, physical exam and specialized testing can help support an accurate diagnosis.

Multiple system atrophy treatment

While there’s currently no cure for multiple system atrophy, treatment focuses on helping you manage symptoms and maintain the best possible quality of life. Because MSA affects different systems in the body, treatment plans are often personalized and may include medication, lifestyle changes and supportive therapies.

Working closely with your care team—which may include a neurologist, physical therapist, speech therapist and other specialists—can help you find strategies that make everyday life more manageable.
