palilalia

This term is a specialized clinical descriptor used primarily in neurology, psychiatry, and speech-language pathology. It describes a specific type of echolalia where the speaker repeats their own words rather than those of another person. The hallmark of this condition is the rhythmic decay of the repetition, where each subsequent iteration becomes faster and quieter.

Because it is a medical diagnosis, the word is almost exclusively used in formal clinical reports or academic literature. It is rarely used in casual conversation unless describing a specific symptom of neurological disorders such as Tourette syndrome or Parkinson's disease.
