1885

Publication of Gilles de la Tourette’s Étude sur une Affection Nerveuse, arguing that the “maladie des tics” was a progressive illness culminating in involuntary cursing (coprolalia). Of his description of nine patients, “only the Marquise de Dampierre unambiguously qualif ies as suffering from Gilles de la Tourette’s disease as originally described and Tourette syndrome as it is now represented in the DSM-IV” (Kushner, 24). Gilles de la Tourette and Charcot differentiated maladie des tics from florid hysteria by ascribing inherited psychological and physiological causes, a progressive course, and resistance to cure (via hypnosis) to the former (Kushner, 29-32).
