Palilalia is defined as the repetition of the speaker's words or phrases, often for a varying number of repeats. Repeated units are generally whole sections of words and are larger than a syllable, with words being repeated the most often, followed by phrases, and then syllables or sounds.
A speech error, commonly referred to as a slip of the tongue [1] (Latin: lapsus linguae, or occasionally self-demonstratingly, lipsus languae) or misspeaking, is a deviation (conscious or unconscious) from the apparently intended form of an utterance. [2]
A disfluence or nonfluence is a non-pathological hesitance when speaking, the use of fillers (“like” or “uh”), or the repetition of a word or phrase. This needs to be distinguished from a fluency disorder like stuttering with an interruption of fluency of speech, accompanied by "excessive tension, speaking avoidance, struggle behaviors, and secondary mannerism".
Often, fluency will also be considered a category under speech, encompassing the characteristics of rhythm, rate, and emphasis of the sound produced. [ 1 ] A language impairment is a specific deficiency in understanding and sharing thoughts and ideas, i.e. a disorder that involves the processing of linguistic information.
Patients with Wernicke's aphasia demonstrate fluent speech, which is characterized by typical speech rate, intact syntactic abilities and effortless speech output. [3] Writing often reflects speech in that it tends to lack content or meaning. In most cases, motor deficits (i.e. hemiparesis) do not occur in individuals with Wernicke's aphasia. [4]
The differentiation of speech production into only two large sections of the brain (i.e. Broca's and Wernicke's areas), which was accepted long before medical imaging techniques, is now considered outdated. Broca's area was first suggested to play a role in speech function by the French neurologist and anthropologist Paul Broca in 1861.
The word comes from the Greek κόπρος (kópros), meaning "dung, feces", and λαλιά (laliā́) "speech", from λαλεῖν (laleîn) "to talk". [ 1 ] Coprolalia is an occasional characteristic of tic disorders , in particular Tourette syndrome , although it is not required for a diagnosis of Tourette's and only about 10% of Tourette's ...
Klazomania (from the Greek κλάζω ("klazo")—to scream) refers to compulsive shouting; [1] it has features resembling the complex tics such as echolalia, palilalia and coprolalia seen in tic disorders, but has been seen in people with encephalitis lethargica, alcohol use disorder, and carbon monoxide poisoning.
