Childhood-Onset Fluency Disorder

To define Childhood-Onset Fluency Disorder: Persistent speech disruptions like sound repetitions and blocking, commonly called stuttering, causing anxiety and communication challenges.

Overview

Description

Childhood-Onset Fluency Disorder, commonly known as stuttering, is characterized by disturbances in the normal fluency and time patterning of speech that are inappropriate for the individual's age and language skills, persist over time, and cause anxiety about speaking or limitations in communication. It typically involves sound or syllable repetitions, prolongations, broken words, blocking, circumlocutions, or monosyllabic whole-word repetitions.

Prevalence

Estimated 5% of children experience stuttering at some point, with approximately 1% persisting into adulthood. More common in males than females (ratio about 2–4:1).

Age of Onset

Typically begins between ages 2 and 7, most often before age 6.
