Stammering tends to be most common in young children and has often resolved spontaneously by the time the child is older. The typical age of onset is 2 to 7 years of age with a peak at age 5 years. Estimates are that up to 3 to 4 percent of individuals may have Stammered at some time in their lives. Approximately 80 percent of young children who Stammer are likely to have a spontaneous remission over time.Preschoolers and school-age children who Stammer exhibit an increased incidence of social anxiety, school refusal, and other anxiety symptoms.
