Stuttering is a speech disorder in which the flow of speech is interrupted by:
- Repetition or prolongation of sounds, words, or syllables
- An inability to begin a word
In an attempt to speak, the person who is stuttering may:
- Frequently blink the eyes
- Have abnormal facial or upper body movements
The cause of stuttering is not completely understood. Some experts have suggested that stuttering may occur when:
- A child's ability to speak does not match his verbal demands
- There are psychological factors in a child’s life such as mental illness, extreme stress
- Problems occur in the connections between muscles, nerves, and areas of the brain that control speech
- There are problems in the part of the brain that controls the timing of speech muscle activation
