perseveration
The persistent repetition of words, phrases, or responses despite changed circumstances.
Full Definition
Perseveration is a symptom characterized by the inappropriate repetition or continuation of a behavior, thought, or speech pattern. It can manifest as verbal perseveration (repeating words or phrases), motor perseveration (repeating movements), or cognitive perseveration (inability to shift mental sets). This symptom is commonly observed in neurocognitive disorders, autism spectrum disorders, and certain psychotic conditions. In documentation, it's important to specify the type and context of perseverative behavior for accurate clinical assessment.
Usage
Usage note: Distinguish from normal repetition by noting inappropriateness to context and resistance to redirection.
