Multiple system atrophy- parkinsonian type (MSA-P) is a rare condition that causes symptoms similar to Parkinson disease. However, people with MSA-P have more widespread damage to the part of the nervous system that controls important functions such as heart rate, blood pressure, and sweating.
The other subtype of MSA is MSA-cerebellar. It mainly affects areas deep in the brain, just above the spinal cord.
Shy-Drager syndrome; Neurologic orthostatic hypotension; Shy-McGee-Drager syndrome; Parkinson plus syndrome; MSA-P; MSA-C
The cause of MSA-P is unknown. The affected areas of the brain overlap with areas affected by Parkinson disease, with similar symptoms. For this reason, this subtype of MSA is called parkinsonian.
MSA-P is most often diagnosed in men older than 60.
MSA damages the nervous system. The disease tends to progress rapidly. About one half of people with MSA-P have lost most of their motor skills within 5 years of onset of the disease.
Symptoms may include:
Other symptoms that may occur with this disease:
There is no cure for MSA-P. There is no known way to prevent the disease from getting worse. The goal of treatment is to control symptoms.
Dopaminergic medicines, such as levodopa and carbidopa, may be used to reduce early or mild tremors.
But, for many people with MSA-P, these medicines do not work well.
Medicines may be used to treat low blood pressure.
A pacemaker that is programmed to stimulate the heart to beat at a rapid rate (faster than 100 beats per minute) may increase blood pressure for some people.
Constipation can be treated with a high-fiber diet and laxatives. Medicines are available to treat erection problems.
The following groups can provide more information on MSA-P:
Outcome for MSA is poor. Loss of mental and physical functions slowly get worse. Early death is likely. People typically live 7 to 9 years after diagnosis.
Call your provider if you develop symptoms of this disorder.
Call your provider if you have been diagnosed with MSA and your symptoms return or get worse. Also call if new symptoms appear, including possible side effects of medicines, such as:
If you have a family member with MSA and their condition declines to the point that you are unable to care for the person at home, seek advice from your family member's provider.
