82/100Rarity: very rare
TechnicalRegister
A psychomotor syndrome characterised by features such as stupor, mutism, posturing, negativism and waxy flexibility.
The patient's catatonia responded dramatically to a lorazepam challenge, and within an hour she was speaking and moving freely again.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
