Necro, but as this is still showing high on the Google results and has responses from only a year ago... This is an incorrect summary of this article. The article states that it does not fit the definition of a stutter because, by occuring at the end of the word, it does not prevent or prolong the communication (because the repetition occurs after the point has been communicated). Per the article, this prevention/delay of communication is part of the WHO's definition of a stutter. However, it says "They [final-word disfluencies] do not fit the patterns usually found in developmental stuttering, but they appear to be related." It also says that although it may look similar to palilalia, which is associated with Parkinsons, that it does not appear to be the same phenomenon. It notes that the distinction between palilalia and word-final disfluency may not always be clear/sharp. However, it advises that, "To some extent, palilalia resembles word-final repetitions because the final part of an utterance is often, but not always, affected (Van Borsel, in press). However, the repetitions in palilalia usually involve longer fragments, i.e. words and even whole phrases; and the number of times a fragment is repeated is often considerable, compared to the word-final repetitions outlined above." So, this is important because the article basically states the opposite of what you claim. It looks more like palilalia than a traditional stutter. It does not meet the definition for a stutter. However, it does appear to be related to stuttering and does not appear to be related to palilalia. That having been said, more updated sources advise that it appears to present more similar to other non-stuttering-like disfluencies such as interjections, phrase repetitions and revisions than to stutter-like disfluencies. It is generally classified as an "atypical" disfluency. And, per other sources, does seem to have a correlation with autism spectrum disorder, possibly with ADHD (less well researched than ASD). However, does appear to occur without those diagnoses as well. https://doi.org/10.1044/2023_PERSP-22-00209 https://stutteringtherapyresources.com/blogs/blog/what-about-those-atypical-disfluencies
