Stuttering is a disorder where speech is interrupted by repeated movements and fixed postures of the organs involved in speech production. These interruptions can often have struggle and tension, and unusual movements of the body and face. The speech disruptions of stuttering can be mild or severe. In severe cases, a speech interruption of stuttering can last for 30 seconds.
What causes stuttering?
There are many theories and popular beliefs about what causes stuttering. However, despite considerable scientific research from the second half of the 20th century, the cause of the disorder remains a mystery. All we can say at present is that stuttering involves some problem with the neural processing—the brain activity—that supports speech production.
In short, stuttering is a physical disorder and is not caused by psychological factors such as nervousness or stress, or parenting practices, or the way parents communicate with their children when they are young.
However, psychological factors such as anxiety or stress can make stuttering worse. Stuttering tends to run in families, and it is generally accepted that this is because genetics is involved in its cause. However, the precise nature of genetic inheritance is unknown at the moment.
The onset of stuttering
Stuttering is common. A recent study that followed a group of Australian infants found that by three years of age 8% of them had begun to stutter, and 12% of them had begun by four years of age. Onset typically occurs as children are starting to put words together into short utterances. The onset of stuttering can be gradual or sudden, and at onset the severity of stuttering can be mild or severe. In a few cases, onset can be so sudden and severe that parents think their child has a serious illness.
In most cases, the first sign of stuttering is the child repeating syllables such as "I…I…I…I…wanna…" or "Where…where…where….. where is ….?" Stuttering may change soon after it begins and the child may start to show fixed postures of the speech mechanism. For example, instead of repeating syllables, the child may hold the lips and tongue in one position for a while. This can seem to be a complete stoppage of speech as the child attempts to start a word, such as in "…………………can I have a drink." Soon after onset, sounds may be prolonged during moments of stuttering, such as in "wwwwwwwwhere is my drink?” Often, as stuttering develops, children show signs of effort and struggle while speaking.
Natural recovery from stuttering by adulthood, without therapy, occurs often. At present, it is not possible to say whether an individual child will recover naturally or will require therapy. We recommend that all children who begin to stutter during the pre-school years should receive therapy.
The impact of stuttering on daily life
The impact of stuttering for people will differ. For example, someone who stutters only occasionally may experience extreme frustration and anxiety about speaking, while another person whose stuttering is more severe may not be affected in the same way. There is no doubt, though, that stuttering interferes with communication as soon as it begins in pre-school children. Sometimes, children show signs of frustration about their stuttering soon after onset. More commonly, school-age children report feelings of embarrassment about stuttering when answering questions or reading aloud in class. Adults whose work requires effective communication may find their stuttering prevents attainment of their vocational potential.
Stuttering may interfere with social interactions and may lead to development of social anxiety. Social anxiety can significantly impact day-to-day life. More seriously, it is known that adults who come to speech clinics seeking help for their stuttering are greatly at risk of having social anxiety disorder, also known as social phobia. Social anxiety disorder is a debilitating condition. It involves constant fear of humiliation, embarrassment and negative evaluation in social situations. Sufferers experience extreme distress in social situations. They can experience difficulty participating in relationships at work, socially, and with partners and friends and therefore become socially isolated.
Early intervention for stuttering during the pre-school years is so important because it is known that social anxiety disorder starts to emerge in children soon after seven years of age.
Frequently asked questions (FAQs)
Can stuttering be cured?
As genetics is involved in stuttering it is not really right to think about a cure. It is better to think about effective intervention, and that certainly is possible. Clinical trials are showing that early intervention with the right treatment can help with a great chance that stuttering will not return. Treatment later in life is a different matter. Clinical trials have shown that teenagers and adults who stutter can learn to control stuttering if they want to, and that anxiety about speaking can be managed. But it is much simpler and more effective to have treatment during the pre-school years.
Do anxious people stutter or does stuttering make people anxious?
Anxiety does not cause stuttering; stuttering can make people anxious. And anxiety can make stuttering worse, which can then make the anxiety worse. So it can become a really negative cycle of events.
Is stuttering caused by a physical problem with the brain?
At present it looks like stuttering involves some problem with the neural processing—the brain activity—that supports speech production. That just means that stuttering is a physical problem, not a psychological problem as was once thought.
What can I do if my child is bullied at school about stuttering?
This can have serious consequences for a child who stutters—or any child—and needs to be stopped. It is best to get advice from a speech pathologist who specialises in stuttering. You also need to talk to the school teacher.
Are there drugs to help with stuttering?
At the moment there are no drugs that can provide effective help with stuttering.
Is there surgery to help stuttering?
There is no surgery to help stuttering.
