RIS was defined by the RBD Questionnaire\u2013Hong Kong (RBDQ\u2010HK) as the presence of residual sleep\u2010related injuries or potential injurious behaviors for at least once a month after at least 1 year of treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 15 out of 133 (11.3%) patients with iRBD (age at diagnosis = 66.5\u2009\u00b1\u20097.3\u2009years, 77.4% male) had RIS after 2.7\u2009years of treatment.

RIS was probably associated with a higher risk of developing dementia with Lewy bodies (adjusted hazard ratio [95% confidence interval], 5.47 [1.71\u201317.46], adjusted for onset age of RBD), but not Parkinsons's disease in the follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>RIS is not uncommon in patients with iRBD despite long\u2010term medication treatment. An earlier onset and more severe clinical profile are associated with RIS. The prediction of RIS toward dementia with Lewy bodies but not PD suggests that RIS may probably help to identify the specific risk of different subtypes of \u03b1\u2010synucleinopathy. \u00a9 2020 International Parkinson and Movement Disorder Society<\/jats:p><\/jats:sec>","DOI":"10.1002\/mds.28210","type":"journal-article","created":{"date-parts":[[2020,8,3]],"date-time":"2020-08-03T09:57:42Z","timestamp":1596448662000},"page":"2077-2085","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Residual Injurious Symptoms and Its Association With Neurodegenerative Outcomes in Idiopathic Rapid Eye Movement Sleep Behavior Disorder: A Retrospective, Longitudinal <scp>Follow\u2010up<\/scp> Study"],"prefix":"10.1002","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9906-8712","authenticated-orcid":false,"given":"Jing","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Psychiatry, Faculty of Medicine The Chinese University of Hong Kong  Shatin, N.T.
