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 of, history and/or discovery:
“The history of persecution is a history of endeavors to cheat nature, to make water run up hill, to twist a rope of sand.”
—Ralph Waldo Emerson (1803–1882)
“The history of any nation follows an undulatory course. In the trough of the wave we find more or less complete anarchy; but the crest is not more or less complete Utopia, but only, at best, a tolerably humane, partially free and fairly just society that invariably carries within itself the seeds of its own decadence.”
—Aldous Huxley (1894–1963)
“However backwards the world has been in former ages in the discovery of such points as GOD never meant us to know,—we have been more successful in our own days:Mthousands can trace out now the impressions of this divine intercourse in themselves, from the first moment they received it, and with such distinct intelligence of its progress and workings, as to require no evidence of its truth.”
—Laurence Sterne (1713–1768)
