palilalia
Pronunciation: pal-ih-LAY-lee-ah
Speech disorder characterized by involuntary repetition of words or phrases with increasing rapidity and decreasing intelligibility.
Full Definition
Palilalia is a speech disorder involving the involuntary repetition of words, phrases, or sentences, typically with progressively increasing speed and decreasing volume and clarity. This condition is most commonly associated with Parkinson's disease and other parkinsonian syndromes, but can also occur with Tourette's syndrome, autism spectrum disorders, and certain types of brain injury affecting the basal ganglia or frontal cortex. The repetitions usually involve the patient's own words rather than those of others (which would be echolalia). Clinical documentation should note the frequency of episodes, triggers, and impact on communication. Speech therapy interventions may help manage this condition, particularly when it significantly impairs functional communication.
Usage
Usage note: Distinguish from echolalia (repeating others' words) and stuttering (difficulty with speech initiation or flow).
