History of Discovery
A movement disorder similar to PKD was first mentioned in research literature in 1940 by Mount and Reback. They described a disorder consisting of attacks of involuntary movements but unlike PKD, the attacks lasted minutes to hours and were found to be caused by alcohol or caffeine intake. They named it paroxysmal dystonic choreoathetosis. Kertesz later described another new movement disorder in 1967. He described a disorder that was induced by sudden movements, and responded to anticonvulsants, naming it paroxysmal kinesigenic choreoathetosis. Finally in a review in 1995 Demirkiran and Jankovic stated the disease should be called paroxysmal kinesigenic dyskinesia instead, pointing out that the attacks could manifest as any form of dyskinesia, not just choreoathetosis.

Famous quotes containing the words history and/or discovery:
“Anything in history or nature that can be described as changing steadily can be seen as heading toward catastrophe.”
—Susan Sontag (b. 1933)
“Your discovery of the contradiction caused me the greatest surprise and, I would almost say, consternation, since it has shaken the basis on which I intended to build my arithmetic.... It is all the more serious since, with the loss of my rule V, not only the foundations of my arithmetic, but also the sole possible foundations of arithmetic seem to vanish.”
—Gottlob Frege (1848–1925)
