Childhood - Onset Fluency Disorder
A disturbance in speech fluency that includes a number of problems with speech, such as repeating syllables or words, prolonging certain sounds, making obvious pauses, or substituting words to replace ones that are difficult to articulate.
Occurs twice as often among boys as among girls. Begins most often in children by the age of 6, and 98% of cases occur before the age of 10. Approximately 80% of children who stutter before they enter school will no longer stutter after they have been in school a year or so.
