Echopraxia
From Wikipedia, the free encyclopedia
Echopraxia is the involuntary repetition or imitation of the observed movements of another. It is closely related to echolalia, the involuntary repetition of another's speech. The etymology of the term is from Ancient Greek: "ἠχώ (ēkhō) from ἠχή (ēkhē “sound”)" and "πρᾶξις (praksis, “action, activity, practice”)". Echopraxia is also known as echomotism.[1]
Even though it is considered a tic, it is a behaviour characteristic of some people with autism,[2] Tourette syndrome, Ganser syndrome, schizophrenia (especially catatonic schizophrenia), some forms of clinical depression and some other neurological disorders.
