Of the two subgroups of MSA that are now recognized, MSA-C is more commonly found in Japan, whereas MSA-P is the variety most often diagnosed in Western countries.
Why is MSA no longer called Shy Drager syndrome
The name Shy Drager Syndrome was changed to MSA in 1998 after a consensus statement was published that clearly defined the broad spectrum of effects the condition could have.

The paper outlined specific diagnostic criteria for the condition and suggested the name change to better reflect the way the disease originates. In addition to the name change, the 1998 paper also categorized the condition into two subgroups.MSA-P: features more parkinsonian symptoms like tremors, rigid muscles, and movement problemsMSA-C: has more cerebellar features, like coordination problems alongside speech or vision difficulties
What are the signs and symptoms of Shy Drager syndrome
As described in the revised name, multiple system atrophy, atrophy is the hallmark symptom of MSA. There’s a wide range of effects when it comes to MSA, based on the severity of the condition and what areas of the body are most impacted.

Some of the symptoms reported with MSA include:fatigueweaknessblurred visionproblems with bowel or bladder controlincontinenceerectile dysfunctionconstipationdry skin
Eventually, most people with this condition progress to some degree of autonomic dysfunction.

The diagnosis may further be categorized based on unique symptoms, and what body systems are affected. As mentioned above, MSA-P has a similar presentation as Parkinson’s disease, with symptoms like:slowed voluntary movementsmuscle stiffnesspoor balancejerking movements in the hands or fingers
About 90% of all people with MSA will experience MSA-P symptoms.

The one symptom that’s common in Parkinson’s disease that’s rarely seen in MSA-P is the “pill-rolling” resting tremor. This is seen in less than 10% of people with MSA-P. Cerebellar symptoms, which impact about 20% of people with MSA, include things like:uncoordinated voluntary movementsprogressive balance lossslurred speechjerkiness to eye movements
Other symptoms that can appear in either type of MSA include:exaggerated reflexesincreased muscle tonemuscle spasmscurvature of the spinenoisy or hoarse breathing (stridor)sleep disorderscognitive problems
Is Shy Drager syndrome hereditary
Researchers aren’t really sure what causes MSA, but there appear to be some links in both environmental and genetic factors.

Specifically, alterations in the alpha-synuclein (SNCA) gene may play a role in the development of MSA, but more research is needed to fully understand the condition.
How do you diagnose Shy Drager syndrome
If your healthcare professional suspects you have a neurologic disorder like MSA, diagnosis will start with a review of your personal and family medical history, and what symptoms you’re experiencing.

Some other possible testing methods that might be used include:autonomic testingbladder function testsmagnetic resonance imaging (MRI) of the brainpositron emission tomography (PET) scan of the brain
Another test — which is more of a medication challenge — is a trial of levodopa. Levodopa is a medication often used to treat Parkinson’s disease.

If your doctor prescribes it to you and you have little to no improvement, this is often a sign that you have MSA. The only true “gold standard” testing that can be done to confirm an MSA diagnosis, though, is post-mortem testing.

How quickly the disease progresses and how severe your symptoms depend in part on how old you were at the time of diagnosis. People who develop symptoms later in life are female, fall a lot, or who have severe autonomic symptoms usually have the highest mortality rates.
Takeaway
While it can be difficult to diagnose MSA and even more difficult to treat it, it’s a disease that usually doesn’t appear until your sixth decade of life or later.
