By grouping related but distinct syndromes into one label, the MUS classification fails to inform clinicians about their patients\u2019 health condition. In research settings, the MUS classification makes patient samples more heterogeneous, obstructing research into the underlying pathology of FSS. Long-term studies have shown that MUS are often appraised as medically explained symptoms at follow-up and vice versa, raising doubts about the reliability of this distinction.<\/jats:p>","DOI":"10.3390\/ijerph16071247","type":"journal-article","created":{"date-parts":[[2019,4,8]],"date-time":"2019-04-08T11:54:52Z","timestamp":1554724492000},"page":"1247","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Medically Unexplained Symptoms (MUS): Faults and Implications"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5249-6963","authenticated-orcid":false,"given":"Michiel","family":"Tack","sequence":"first","affiliation":[{"name":"Independent researcher, Sint-Laurentiusstraat 87, 9700 Oudenaarde, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Guo, D., Kleinst\u00e4uber, M., Johnson, M.H., and Sundram, F.
