Approximately 1% of the US population stutters at any given point in time. More often than not, stuttering in children is just the result of nervousness or learning the literary ropes, so to speak. In some cases, however, the repeated syllables may point to more difficult challenges for the child and parents may need to seek out help for a stuttering problem. While there is some evidence of a possible genetic link, researchers say some of their studies point to emotional roots.
A study published in the Journal of Communication Disorders in June 2006 found that emotional development is linked to childhood stuttering. To complete the study, researchers had parents of 3-to-5-year-olds fill out a 100-question survey to determine how the stuttering related to the child’s response to emotional events. Researchers found that those who stutter are more emotionally aroused by stressful situations, take longer to settle down from stimulating events and are less able to control their attention than people who do not stutter. “Our findings seem to indicate that kids with behavioral and emotional issues are at greater risk of stuttering, that not all aspects of their emotional reactions can be blamed on stuttering, and some of these reactions may pre-date the onset of stuttering and actually contribute to its onset and development,” concludes study co-author Tedra Walden.
What puzzles scientists is that there seems to be no real biological cause for stuttering in children. They have noted that there is increased dopamine activity in the prefrontal cortex in a person who stutters, although the actual structure of the brain looks the same as anyone else’s. Some Positron Emission Test results show some changes in the brain where speech motor function is involved, but there is still no consensus as to which areas in the brain are active or inactive during stuttering.
The stutter cure often involves parental support, which is why stuttering in children is treated in therapy, yet some sessions require the parents to be there too. While a parent can’t possibly protect the child from every incidence of stress, anger or frustration, he or she can certainly encourage progress at home. Parents should make direct eye contact with their child when speaking, set aside time each day to communicate, avoid interrupting and never chastise.
