Speech that exhibits deviations in continuity, fluidity, ease of rate and effort, with hesitations or repetition of sounds, words, or phrases; lack of skillfulness in speech. Disfluency is normal in pre-school language development. In later years, it can be due to congenital conditions such as Down’s syndrome, or acquired—either early, as in stuttering, or late, as may occur in Parkinson’s disease.
