All patients had signs of dystonia or components of their arm tremor that were compatible with dystonic tremor, and none had true akinesia with fatiguing or decrement, even after a mean follow\u2010up period of 5.8 years. All patients had normal dopamine transporter SPECT scans. Clinicians should be aware that primary adult\u2010onset dystonia can present with an asymmetric resting arm tremor, with impaired arm swing and sometimes also facial hypomimia or a jaw tremor, but without evidence of true akinesia. Given the important consequences of misdiagnosing such patients as PD, in cases with diagnostic uncertainty functional imaging should be considered. Among patients suspected of PD, dystonic tremor may be one cause of SWEDDs (Scans Without Evidence of Dopaminergic Deficit). \u00a9 2007 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.21685","type":"journal-article","created":{"date-parts":[[2007,8,21]],"date-time":"2007-08-21T16:46:39Z","timestamp":1187714799000},"page":"2210-2215","source":"Crossref","is-referenced-by-count":210,"title":["Patients with adult\u2010onset dystonic tremor resembling parkinsonian tremor have scans without evidence of dopaminergic deficit (SWEDDs)"],"prefix":"10.1002","volume":"22","author":[{"given":"Susanne A.","family":"Schneider","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark J.","family":"Edwards","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pablo","family":"Mir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Cordivari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juzar","family":"Hooker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Dickson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niall","family":"Quinn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kailash P.","family":"Bhatia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,8,21]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.51.6.745"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410440704"},{"issue":"1","key":"e_1_2_7_4_2","first-page":"A274","article-title":"Long\u2010term follow\u2010up of pateints with scans without evidence of dopaminergic deficit (SWEDD) in the ELLDOPA study","volume":"64","author":"Marek K","year":"2005","journal-title":"Neurology"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.10774"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.10609"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.61.7.1044"},{"issue":"1","key":"e_1_2_7_8_2","first-page":"A298","article-title":"B\u2010CIT scans without evidence of dopaminergic deficit (SWEDD) in the ELLDOPA\u2010CIT and CALM\u2010CIT study: longterm imaging assessment","volume":"60","author":"Marek K","year":"2003","journal-title":"Neurology"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-005-4008-5"},{"issue":"3","key":"e_1_2_7_10_2","first-page":"2","article-title":"Consensus statement of the Movement Disorder Society on tremor","volume":"13","author":"Deuschl G","year":"1998","journal-title":"Mov Disord"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s004150070053"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.21043"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870090110"},{"issue":"3","key":"e_1_2_7_14_2","first-page":"105","article-title":"Writers' cramp\u2010a focal dystonia","author":"Sheehy MP","year":"1982","journal-title":"Brain"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awg142"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.20075"},{"key":"e_1_2_7_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870080320"}],"container-title":["Movement Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmds.21685","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mds.21685","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T09:02:24Z","timestamp":1760950944000},"score":1,"resource":{"primary":{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/10.1002\/mds.21685"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,8,21]]},"references-count":16,"journal-issue":{"issue":"15","published-print":{"date-parts":[[2007,11,15]]}},"alternative-id":["10.1002\/mds.21685"],"URL":"https:\/\/doi.org\/10.1002\/mds.21685","archive":["Portico"],"relation":{},"ISSN":["0885-3185","1531-8257"],"issn-type":[{"value":"0885-3185","type":"print"},{"value":"1531-8257","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,8,21]]}}}
