The story of the word

The Czech neuropsychiatrist Ladislav Haškovec named it in 1901, half a century before the drugs that now cause most cases existed. The name records the only sign visible from outside, the patient who cannot stay in a chair, and undersells what patients describe, which is torment rather than fidgeting. καθίζειν is κατά plus a sitting verb, and the seat words καθέδρα and ἕδρα gave English cathedral and sanhedrin.
