Two main subtypes are recognized: 'subtype C,' characterized predominantly by cerebellar ataxia, and 'subtype P,' characterized predominantly by parkinsonism. MSA is characterized pathologically by the degeneration of striatonigral and olivopontocerebellar structures and glial cytoplasmic inclusions (GCIs) that consist of abnormally phosphorylated alpha-synuclein (SNCA; 163890) or tau (MAPT; 157140) (Gilman et al., 1998; Gilman et al., 2008; Scholz et al., 2009). 'Subtype C' of MSA has been reported to be more prevalent than 'subtype P' in the Japanese population (65-67% vs 33-35%), whereas 'subtype P' has been reported to be more prevalent than 'subtype C' in Europe (63% vs 34%) and North America (60% vs 13%, with 27% of cases unclassified) (summary by The Multiple-System Atrophy Research Collaboration, 2013).&#13; MSA is similar clinically and pathologically to Parkinson disease (PD; 168600) and Lewy body dementia (127750). See also PARK1 (168601), which is specifically caused by mutation in the SNCA gene.&#13; Pure autonomic failure manifests as orthostatic hypotension and other autonomic abnormalities without other neurologic involvement. Although there is some phenotypic overlap, the relationship of pure autonomic failure to MSA is unclear (Vanderhaeghen et al., 1970; Schatz, 1996)." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln">Multiple system atrophy (MSA) is a distinct clinicopathologic entity that manifests as a progressive adult-onset neurodegenerative disorder causing parkinsonism, cerebellar ataxia, and autonomic, urogenital, and pyramidal dysfunction in various combinations. Two main subtypes are recognized: 'subtype C,' characterized predominantly by cerebellar ataxia, and 'subtype P,' characterized predominantly by parkinsonism. MSA is characterized pathologically by the degeneration of striatonigral and olivopontocerebellar structures and glial cytoplasmic inclusions (GCIs) that consist of abnormally phosphorylated alpha-synuclein (SNCA; 163890) or tau (MAPT; 157140) (Gilman et al., 1998; Gilman et al., 2008; Scholz et al., 2009). 'Subtype C' of MSA has been reported to be more prevalent than 'subtype P' in the Japanese population (65-67% vs 33-35%), whereas 'subtype P' has been reported to be more prevalent than 'subtype C' in Europe (63% vs 34%) and North America (60% vs 13%, with 27% of cases unclassified) (summary by The Multiple-System Atrophy Research Collaboration, 2013).&#13; MSA is similar clinically and pathologically to Parkinson disease (PD; 168600) and Lewy body dementia (127750). See also PARK1 (168601), which is specifically caused by mutation in the SNCA gene.&#13; Pure autonomic failure manifests as orthostatic hypotension and other autonomic abnormalities without other neurologic involvement. Although there is some phenotypic overlap, the relationship of pure autonomic failure to MSA is unclear (Vanderhaeghen et al., 1970; Schatz, 1996). [from <a title="Online Mendelian Inheritance in Man" href="http://www.omim.org" class="defSource" target="_blank">OMIM</a>]</div>

<div class="portlet_content ln"><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Multiple system atrophy is a progressive brain disorder that affects movement and balance and disrupts the function of the autonomic nervous system. The autonomic nervous system controls body functions that are mostly involuntary, such as regulation of blood pressure. The most frequent autonomic symptoms associated with multiple system atrophy are a sudden drop in blood pressure upon standing (orthostatic hypotension), urinary difficulties, and erectile dysfunction in men.<br /><br />Researchers have described two major types of multiple system atrophy, which are distinguished by their major signs and symptoms at the time of diagnosis. In one type, known as MSA-P, a group of movement abnormalities called parkinsonism are predominant. These abnormalities include unusually slow movement (bradykinesia), muscle rigidity, tremors, and an inability to hold the body upright and balanced (postural instability). The other type of multiple system atrophy, known as MSA-C, is characterized by cerebellar ataxia, which causes problems with coordination and balance. This form of the condition can also include speech difficulties (dysarthria) and problems controlling eye movement.<br /><br />Multiple system atrophy usually occurs in older adults; on average, signs and symptoms appear around age 55. The condition worsens with time, and affected individuals survive an average of 10 years after the signs and symptoms first appear.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/multiple-system-atrophy">https://medlineplus.gov/genetics/condition/multiple-system-atrophy</a></div></div>

<div class="spaceAbove">A tendency to fall or the inability to keep oneself from falling; imbalance. The retropulsion test is widely regarded as the gold standard to evaluate postural instability, Use of the retropulsion test includes a rapid balance perturbation in the backward direction, and the number of balance correcting steps (or total absence thereof) is used to rate the degree of postural instability. Healthy subjects correct such perturbations with either one or two large steps, or without taking any steps, hinging rapidly at the hips while swinging the arms forward as a counterweight. In patients with balance impairment, balance correcting steps are often too small, forcing patients to take more than two steps. Taking three or more steps is generally considered to be abnormal, and taking more than five steps is regarded as being clearly abnormal. Markedly affected patients continue to step backward without ever regaining their balance and must be caught by the examiner (this would be called true retropulsion). Even more severely affected patients fail to correct entirely, and fall backward like a pushed toy soldier, without taking any corrective steps.</div>
