Clozapine differs from conventional neuroleptics in that it has higher affinity for D1 and lower affinity for D2 dopamine receptors than do conventional antipsychotics, which are relatively selective D2 antagonists. We propose that repetitive stimulation of the D1 receptor by endogenous dopamine, resulting in sensitization of the D1\u2010mediated striatal output in the presence of D2 receptor blockade, is a fundamental mechanism mediating tardive dyskinesia, including the dystonic type. According to this hypothesis, it is primarily the D1 antagonist action of clozapine that accounts for its inability to cause tardive dyskinesia as well as its therapeutic effect in tardive dystonia. Regardless of its mechanism of action, the sustained improvement observed in this case suggests that clozapine should be tried in cases of severe refractory tardive dystonia.<\/jats:p>","DOI":"10.1002\/mds.870090411","type":"journal-article","created":{"date-parts":[[2004,12,31]],"date-time":"2004-12-31T11:36:23Z","timestamp":1104492983000},"page":"441-446","source":"Crossref","is-referenced-by-count":80,"title":["Treatment of severe axial tardive dystonia with clozapine: Case report and hypothesis"],"prefix":"10.1002","volume":"9","author":[{"given":"Joel M.","family":"Trugman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Leadbetter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael E.","family":"Zalis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rose O.","family":"Burgdorf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.
