Stuttering is a speech disorder that stops the natural rhythm or flow of speech. It can involve hesitations, silent blocking and the repetition of sounds, syllables, words or phrases. It usually starts between the ages of 2 and 5 years, and while most toddlers outgrow stuttering without treatment, any persisting stutter should be treated by a speech pathologist as this significantly reduces the risk of stuttering continuing.
What is stuttering?
Stuttering (also called stammering) is a pattern of speech that involves hesitations, repetitions or silent blocks. People who stutter know what they want to say, but have difficulty saying it.
Stuttering can have a strong and negative effect on the stutterer’s view of themselves and their social and work relationships.
It's common for children between the ages of 2 to 5 to go through periods of stuttering.
For around 70 to 75% of children, this is part of learning to speak, and it gets better on its own. It is rare for adults to begin stuttering.
Symptoms of stuttering
Stuttering signs and symptoms can vary greatly between individuals and may include:
- difficulty starting a word, sentence or phrase
- prolonging a word or sounds within a word
- repetition of a sound, syllable or word
- brief silence for certain syllables or pauses within a word (broken word)
- addition of extra words such as 'um' if difficulty moving to the next word is anticipated
Stuttering may also be accompanied by jerks, blinking or tics, and can be worsened by tiredness or stress.
Causes of stuttering
Nobody is certain what causes stuttering. It affects people from all backgrounds, intelligence levels and personalities, although males are more likely to stutter than females. It runs in some families, although it can happen on its own. About 1% of people stutter at any given time.
Stuttering is most likely due to some problem with brain activity that underlies speech production. In short, stuttering is thought to be a physical disorder and is not thought to be caused by psychological factors such as nervousness or stress, or parenting practices. While anxiety does not cause stuttering, it can make it worse, which can then make the anxiety worse.
Treatment of stuttering
Young children benefit most from early intervention with a speech pathologist. Good outcomes have been shown through the Lidcombe Program of Early Stuttering, which was developed in Sydney.
Treatment for adolescents and adults both aims to correct the speech and reduce the anxiety that usually goes with it.
When talking with someone who stutters, be patient and show interest in what is being said, rather than how it is being said, and don’t finish their sentences.
