Palilalia

Uncommon card · No. 122967

Palilalia, a complex tic, is a language disorder characterized by the involuntary repetition of syllables, words, or phrases. It has features resembling other complex tics such as echolalia or coprolalia, but, unlike other aphasias, palilalia is based upon contextually correct speech. It was originally described by Alexandre-Achille Souques in a patient with a stroke that resulted in left-side hemiplegia, although a condition described as auto-echolalia in 1899 by Édouard Brissaud may have been the same condition.
