Short Description or Definition
Perseverative speech, also termed verbal perseveration, is a pathological condition wherein the aspects of spoken communication are repeatedly and unintentionally produced beyond the point at which they should have stopped. These aspects may include action plans/programs for motor speech production, linguistic forms (such as phonemes, syllables, words, and/or word strings), and even concepts or response modes used to convey thoughts and ideas. Subtypes of impairment arising from different stimulus sources, neural mechanisms, and levels of processing indicate that perseverative speech is not a unitary phenomenon but, rather, a complex one linked to a variety of communication disorders and requiring differentiation from other iterative speech behaviors with which it frequently co-occurs and with which it is frequently confused (Christman et al. 2004).
