Stuttering is a speech impediment that is caused when the regular speech pattern is interrupted by repeated syllable or letter sounds. This happens when a person cannot say the word all at once. The person may also experience tremors and eye blinking while stuttering. Stuttering can happen while they’re talking to a bunch of people or to one person. In the UK, stuttering is referred to as stammering or disfluent speech. There are about three million Americans that have been diagnosed with stuttering. It can affect anyone, but the group that it affects the most is children between the ages of 2 to 6 years old. This is the time that they are learning to talk and make sentences. In this age group, boys outnumber the girls in stuttering. With adults, the stuttering rate hovers around 1 percent.

Some research has shown that stuttering may be genetically related. However, most stuttering has seemed to produce a developmental pattern. This is in reference to young children that are just starting to speak and form words and sentences. With them, they stutter when they try to form the right word or sentence to speak out of their mouths. Usually with this type of scenario, the children will outgrow it. There is another type of stuttering that originates from the brain area. This is called a neurogenic disorder. The signals with the brain, nerves and muscled do not connect properly. In this case, the coordination is lacking. This type of stuttering is also present if a person is or has suffered with an injury from the brain or a stroke.
