Stuttering

Definition

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

Causes

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

  • Family history of stuttering
  • Sex: male
  • Age: between 2-6 years of age

Symptoms

Symptoms may include:

  • Repetition of sounds, syllables, words, or phrases
  • Prolongation of sounds within words
  • Between-word pauses and lack of sound
  • Spurting speech
  • Accompanying behaviors, such as:
    • Blinking

    • Lip tremors
    • Tense muscles of the mouth, jaw, or neck
  • Worsening symptoms when speaking in public
  • Improvement in symptoms when speaking in private

Diagnosis

The doctor will ask about your symptoms and medical history. A physical exam will be done. Diagnosis may be based on:

  • Stuttering history
  • Circumstances under which stuttering occurs
  • Speech and language capabilities
  • Evaluation of hearing and motor skills, including a pediatric and neurological examination
  • Further testing and treatment by a speech language pathologist who specializes in communication disorders

Treatment

Treatment can improve stuttering. The main goal is to get and maintain a feeling of control over speech fluency. The doctor or speech therapist can:

  • Evaluate the stuttering pattern
  • Assess what strategies may work best

Treatment may include:

  • Behavioral therapy—This focuses on behavior modifications that can be made to improve fluency.
  • Speech therapy—A primary goal of this type of therapy is to slow the rate of speech.

There is little evidence to support the use of drugs to improve speech fluency.

Prevention

There are no guidelines to prevent stuttering. However, early recognition and treatment may minimize or prevent a life-long problem.
