Multiple system atrophy (MSA) is a sporadic neurodegenerative disease (one of the synucleinopathies) characterized by varying degrees of cerebellar ataxia, autonomic dysfunction, parkinsonism, and corticospinal dysfunction. Patients with multiple system atrophy (MSA) have a mean survival of 8 to 10 years. Some research suggests that this protein may be overexpressed in multiple system atrophy. Sleep-Disordered Breathing in Multiple System Atrophy: Pathophysiology and New Insights for Diagnosis and Treatment. Death, at the end of the illness, generally occurs as a result of respiratory problems given the inability of the nervous system to self-regulate. Multiple system atrophy. Multiple system atrophy (MSA) is a progressive neurodegenerative disorder characterized by symptoms of autonomic nervous system failure such as fainting spells and bladder control problems, combined with motor control symptoms such as tremor, rigidity, and loss of muscle coordination. This led to the use of tracheostomy and noninvasive positive pressure ventilation (NPPV) for the prevention of sudden death. The fundamental cause of multiple system atrophy (MSA) is a loss of oligodendroglial and neuronal cells in the brain and central nervous system. Mayo Clinic does not endorse companies or products. J Clin Sleep Med. Multiple System Atrophy (or Shy-Drager Syndrome) (SDS) (MSA) is a a rare degenerative condition resulting from degeneration of certain nerve cells in the brain and spinal cord. 8600 Rockville Pike Mayo Clinic is a not-for-profit organization. Sudden death in multiple system atrophy (MSA) usually occurs during sleep and was therefore attributed to suffocation resulting from vocal cord abductor paralysis, a characteristic laryngeal finding of MSA. A multidisciplinary approach is needed to prevent sudden death, and this requires an organized system of several medical specialties. 2007 May 8;68(19):1618-21. doi: 10.1212/01.wnl.0000260975.74618.d7.

Formerly called Shy-Drager syndrome, olivopontocerebellar atrophy or striatonigral degeneration, MSA shares many Parkinson's disease-like symptoms, such as slow movement, rigid muscles and poor balance. J Neurol Neurosurg Psychiatry, 78: 327-329 [15] Schrag A, Wenning GK, Quinn N, Ben-Shlomo Y (2008). Pneumonia is the most common cause of death, although irregularities in heartbeat or choking may be responsible for death in some patients. The symptoms reflect the progressive loss of function and death of different types of nerve cells in the brain and spinal cord. Nocturnal stridor has been considered a poor prognostic feature. Sudden death in MSA is hypothesized to be a consequence of disordered central respiration, suffocation caused by sputum and food, upper airway obstruction from NPPV acting on a floppy epiglottis, cardiac autonomic disturbance, or a combination of these factors. On occasions, people can live with Multiple System Atrophy for more than 15 years. This high-risk group was followed by patients with Lewy body dementia, four years earlier; Parkinson disease dementia, 3½ years earlier; and Parkinson disease, one year earlier. Riggin EA.
