What stuttering is
NIDCD states: “Stuttering is a speech disorder characterized by repetition of sounds, syllables, or words; prolongation of sounds; and interruptions in speech known as blocks.” On who stutters: “It occurs most often in children between the ages of 2 and 6 as they are developing their language skills.” And: “Most children outgrow stuttering. Approximately 75 percent of children recover from stuttering.”
Diagnosis
NIDCD states: “Stuttering is usually diagnosed by a speech-language pathologist, a health professional who is trained to test and treat individuals with voice, speech, and language disorders.” For a young child, the SLP “will try to determine if the child is likely to continue his or her stuttering behavior or outgrow it.” NIDCD says the SLP will consider “the family’s history of stuttering, whether the child’s stuttering has lasted 6 months or longer, and whether the child exhibits other speech or language problems.”
On when to evaluate: “Health professionals generally recommend that a child be evaluated if he or she has stuttered for 3 to 6 months, exhibits struggle behaviors associated with stuttering, or has a family history of stuttering or related communication disorders.”
Treatment
NIDCD states: “Although there is currently no cure for stuttering, there are a variety of treatments available.” And: “If you or your child stutters, it is important to work with a speech-language pathologist to determine the best treatment options.”
For children: “Treatment often involves teaching parents about ways to support their child’s production of fluent speech.” For teens and adults: “Many of the current therapies for teens and adults who stutter focus on helping them learn ways to minimize stuttering when they speak, such as by speaking more slowly, regulating their breathing, or gradually progressing from single-syllable responses to longer words and more complex sentences.” And: “Most of these therapies also help address the anxiety a person who stutters may feel in certain speaking situations.”
On medicines, as of that page: “The U.S. Food and Drug Administration has not approved any drug for the treatment of stuttering.” NIDCD also describes electronic devices and self-help groups and says more research is needed on how long device effects last.
In schools
The NIDCD page does not discuss schools. School-based speech services follow federal special education rules; see IEPs and IFSPs and working in schools.
