Three neurologists blinded to the diagnoses recorded dominant and associated movement disorders seen on videos of 31 patients with anti\u2010NMDAR encephalitis (n\u2009=\u200910), BGE (n\u2009=\u200912), and SC (n\u2009=\u20099). Stereotypy was only seen in anti\u2010NMDAR encephalitis (8\/10) and not in BGE and SC (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Perseveration was only seen in anti\u2010NMDAR encephalitis (5\/10) and not in BGE and SC (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Akinesia was more commonly seen in BGE (5\/12) than in anti\u2010NMDAR encephalitis (1\/10, <jats:italic>P<\/jats:italic>\u2009=\u20090.097). Tremor was more commonly seen in BGE (5\/12) than in anti\u2010NMDAR encephalitis (1\/10, <jats:italic>P<\/jats:italic>\u2009=\u20090.097). Chorea was seen in all groups: anti\u2010NMDAR encephalitis (4\/10), BGE (3\/12), and SC (9\/9). Likewise, dystonia was seen in all groups: anti\u2010NMDAR encephalitis (6\/10), BGE (7\/12), and SC (2\/9). Stereotypies or perseveration are suggestive of anti\u2010NMDAR encephalitis, whereas their absence and the presence of akinesia and tremor is more suggestive of BGE. Chorea and dystonia are least discriminating. \u00a9 2014 International Parkinson and Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.25999","type":"journal-article","created":{"date-parts":[[2014,8,22]],"date-time":"2014-08-22T11:47:09Z","timestamp":1408708029000},"page":"1539-1542","source":"Crossref","is-referenced-by-count":90,"title":["Movement disorders in children with anti\u2010NMDAR encephalitis and other autoimmune encephalopathies"],"prefix":"10.1002","volume":"29","author":[{"given":"Shekeeb S.","family":"Mohammad","sequence":"first","affiliation":[{"name":"Neuroimmunology Group, Institute for Neuroscience and Muscle Research, The Kids Research Institute at the Children's Hospital at Westmead University of Sydney Westmead NSW Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor S.C.","family":"Fung","sequence":"additional","affiliation":[{"name":"Movement Disorders Unit, Department of Neurology Westmead Hospital and Sydney Medical School, University of Sydney Sydney Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Padraic","family":"Grattan\u2010Smith","sequence":"additional","affiliation":[{"name":"T.Y.
