"Trousseau's disease:" A description of the gilles de la tourette syndrome 12 years before 1885

French neurologist Georges Gilles de la Tourette first described the syndrome which earned him eponymous fame in 1885. However, a publication dated 1873 by Armand Trousseau included a detailed account of what is currently know as Gilles de la Tourette syndrome (GTS). In Gilles de la Tourette's celebrated 1885 paper, there is a brief mention of the clinical picture described earlier by Trousseau, but Gilles de la Tourette somewhat disregarded it. We present the first English translation of Trousseau's description and argue that this description is more akin to modern conceptualization of GTS than the description of Gilles de la Tourette himself. © 2010 Movement Disorder Society
