Quantification of early autonomic failure as a mortality predictor is lacking. Early neurological and autonomic clinical features were retrospectively reviewed in 49 MSA cases (median age at onset, 56.1 years; 16 women) confirmed by autopsy at Mayo Clinic. When available, the 10\u2010point composite autonomic severity score derived from the autonomic reflex screen provided quantification of the degree of autonomic failure and thermoregulatory sweat test quantitated body surface anhidrosis. Symptoms at onset were autonomic in 50%, parkinsonian in 30%, and cerebellar in 20% of cases. Survival (median [95% confidence interval]) was 8.6 [6.7\u201010.2] years. Survival was shorter in patients with early laboratory evidence of generalized (composite autonomic severity score\u2009\u2265\u20096) autonomic failure (7.0 [3.9\u20109.8] vs. 9.8 [4.6\u201013.8] years; <jats:italic>P<\/jats:italic>\u2009=\u20090.036), and early requirement of bladder catheterization (7.3 [3.1\u201010.2] vs. 13.7 [8.5\u201014.9] years; <jats:italic>P<\/jats:italic>\u2009=\u20090.003) compared with those without these clinical features. On Cox proportional analysis, prognostic indicators of shorter survival were older age at onset (hazard ratio [95% confidence interval], 1.04 [1.01\u20101.08]; <jats:italic>P<\/jats:italic>\u2009=\u20090.03), early requirement of bladder catheterization (7.9 [1.88\u201038.63]; <jats:italic>P<\/jats:italic>\u2009=\u20090.004), and early generalized (composite autonomic severity score\u2009\u2265\u20096) autonomic failure (2.8 [1.01\u20109.26]; <jats:italic>P<\/jats:italic>\u2009=\u20090.047). Gender, phenotype, and early development of gait instability, aid\u2010requiring ambulation, orthostatic symptoms, neurogenic bladder, or significant anhidrosis (thermoregulatory sweat test\u2009\u2265\u200940%) were not indicators of shorter survival. Our data suggest that early development of severe generalized autonomic failure more than triples the risk of shorter survival in patients with MSA. \u00a9 2014 International Parkinson and Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.25927","type":"journal-article","created":{"date-parts":[[2014,6,7]],"date-time":"2014-06-07T07:05:43Z","timestamp":1402124743000},"page":"1151-1157","source":"Crossref","is-referenced-by-count":106,"title":["Multiple system atrophy: Prognostic indicators of survival"],"prefix":"10.1002","volume":"29","author":[{"given":"Juan J.","family":"Figueroa","sequence":"first","affiliation":[{"name":"Department of Neurology Medical College of Wisconsin Milwaukee WI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wolfgang","family":"Singer","sequence":"additional","affiliation":[{"name":"Department of Neurology Mayo Clinic Rochester MN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajay","family":"Parsaik","sequence":"additional","affiliation":[{"name":"Department of Neurology Mayo Clinic Rochester MN"},{"name":"Department of Psychiatry and Behavior Sciences University of Texas Health Science Center Houston TX"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo E.","family":"Benarroch","sequence":"additional","affiliation":[{"name":"Department of Neurology Mayo Clinic Rochester MN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
