Palilalia, Palipraxia and Paliskepsi

Palilalia is the repetition or echoing of one's own spoken words.
It is a complex tic and may sound like stuttering.Palilalia comes from the Greek words  palin (again) + lalein  (to babble)

Palilalia is often times accompanied by other complex tic disorders, like echolalia and coprolalia.
It can be symptoms of Tourette syndrome, Parkinson's disease, obsessive–compulsive disorder, or autism.

A child who has palilalia may say, "I want to go to the store" and then immediately whisper, "go to the store."

Palipraxia is the repetition of self-generated movements. It is a complex motor tic in Tourette's Syndrome


An example of Palipraxi would be someone looking to the left than involuntarily looking to the left again.

Paliskepsi

Paliskepsi is the repetition of one’s own thoughts and is the mental form of palilalia. Paliskepsi can make thinking quite difficult as it can cause a phrase or single word to be repeated.Sometimes Paliskepi can be stopped by a vocal tic.
