Childhood-Onset Fluency Disorder (more commonly known as Stuttering) is a communication disorder characterized by a disturbance in the normal fluency and time patterning of speech that is inappropriate for an individual's age. The disorder is characterized by frequent repetitions or prolongations of sounds or syllables. Other speech deficits include: (1) single words that are broken up (e.g. - pauses within a word), (2) audible or silent blocks (i.e. - filled or unfilled pauses in speech), (3) circumlocutions (i.e. - word substitutions to avoid problematic words), (4) words produced with excess physical tension, and (5) monosyllabic whole-word repetitions (e.g., 'He-he-he-he is here“).
Disturbances in the normal fluency (i.e. - dysfluencies) and time patterning of speech that are inappropriate for the individual’s age and language skills, persist over time, and are characterized by frequent and marked occurrences of at least 1
of the following:
The disturbance causes anxiety about speaking or limitations ineffective communication, social participation, or academic or occupational performance, individually or in any combination.
The onset of symptoms is in the early developmental period. (Adults are diagnosed as adult-onset fluency disorder).
The disturbance is not attributable to a speech-motor or sensory deficit, disfluency associated with neurological insult (e.g. - stroke, tumour, trauma), or another medical condition and is not better explained by another mental disorder.
