Preferred Label : Developmental speech fluency disorder;
ICD-11 definition : Developmental speech fluency disorder is characterised by frequent or pervasive disruption
of the normal rhythmic flow and rate of speech characterised by repetitions and prolongations
in sounds, syllables, words, and phrases, as well as blocking and word avoidance or
substitutions. The speech dysfluency is persistent over time. The onset of speech
dysfluency occurs during the developmental period and speech fluency is markedly below

in social communication, personal, family, social, educational, occupational or other
important areas of functioning. The speech dysfluency is not better accounted for
by a Disorder of Intellectual Development, a Disease of the Nervous System, a sensory
impairment, or a structural abnormality, or other speech or voice disorder.;
