Conceptions and information regarding the onset and development of stuttering in early childhood have undergone large changes during the past three decades. In general, the notions that stuttering begins with normal disfluency and that, once it exists, the disorder typically develops in an ascending manner following a stage-like progression, have been greatly challenged, if not discarded. A review of highlights of the findings of the Illinois Stuttering Research Program reveals strong genetic components to stuttering. Consider- able variability is seen in the event of onset. Early symptomatology is complex, often containing characteris- tics seen in advanced stuttering, and tends to be moderate or even higher in severity. Generally, the developmental course of stuttering is characterized by diverse pathways, with the great majority of children exhibiting natural recovery within 3 years after onset. The findings have significant clinical implications. |
