Why Do I Stutter? (Part 2)

speech-language Oct 25, 2021

For people who stutter, stuttering will most likely develop between the ages of 2 and 6. However, some children will have typical disfluencies that they outgrow in less than 6 months that do not turn into atypical disfluencies. If your child stutters for more than 6 months they may need treatment from a speech-language pathologist. There are risk factors that may be a red flag that the child will not outgrow stuttering.


These possible risk factors include:

  • Boys are found to be at a higher risk to not outgrow stuttering than girls.
  • Having other people in the family who stutter.
  • A child who continues to stutter after 6 or 12 months with no improvement.
  • A child’s language develops slower or has a different speech and language impairment that is occurring at the same time.

We now know when stuttering usually develops. But you may now be wondering, what even causes stuttering? There is not one thing that is said to cause stuttering. Most importantly no one caused you or your child to necessarily stutter. However, environmental factors like where others may be making fun of them, finishing the child’s thoughts, interrupting the child when they are speaking, negative thoughts about speaking ability, anxiety, etc, can play a role in having disfluencies more likely to occur. How a child reacts (sensitivity) and can cope with those environmental factors during a stuttering event influences the psychological part of stuttering (see blog post about “What is Stuttering? (part 1). Both genetics and brain differences may cause stuttering.


Genetics: Research shows that there may be gene mutations that are tied to stuttering. Simply, these gene mutations cause an enzyme signal to be disrupted on the way to its cell.


Brain and brain wiring differences:

  • Nerve cells and their connections to each other on the right side versus the left side of the brain.
  • Connectivity throughout the brain in relation to speech motor control.
  • Decreased blood flow to certain speech and language areas of the brain.
  • Processing language.
  • Memory in relation to speech sounds.
