Secondary PD has seen reported to occur in some conditions, mainly in multiple sclerosis and head trauma. The anatomic origin of the lesion is also rarely seen at the spinal cord. Our objective was to describe four patients with paroxysmal dystonia secondary to spinal lesions during the recovering phase of a neuromyelitis optica (NMO) bout. In the reviewed literature, we do not find any report of PD related to NMO.<\/jats:p>","DOI":"10.1590\/s0004-282x2012005000011","type":"journal-article","created":{"date-parts":[[2012,2,18]],"date-time":"2012-02-18T02:43:07Z","timestamp":1329532987000},"page":"271-272","source":"Crossref","is-referenced-by-count":18,"title":["Paroxysmal dystonia and neuromyelitis optica"],"prefix":"10.1590","volume":"70","author":[{"given":"Felipe R.","family":"Schmidt","sequence":"first","affiliation":[{"name":"Universidade Federal do Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Flavio Henrique R.","family":"Costa","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernanda M.L.C.","family":"Silva","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henryk","family":"Maultasch","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Lucia","family":"Rosso","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denise H.","family":"Nicaretta","sequence":"additional","affiliation":[{"name":"Santa Casa de Miseric\u00f3rdia do Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James P. de","family":"Mattos","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergio A.P.","family":"Novis","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro, Brazil;
