Stuttering is a speech disorder affecting the flow of words, characterized by the repetition of syllables, hesitation or interruption of speech. Stuttering is a very common condition in children, with nearly one child in a hundred affected. Usually, stuttering appears in the early years of speech, and decreases or disappears before adulthood. In general, men are much more affected than women. There are different types of stuttering:
  • clonic stuttering that causes uncontrollable and jerky repetition of a syllable or sound;
  • tonic stuttering that blocks the initiation of the diction of a word.

Traditionally, stuttering is intermittent and accented by elements such as fatigue or stress.


Stuttering is characterized by the following symptoms:
  • abnormal flow to speech;
  • the repetition of certain syllables;
  • hesitation before or between certain words;
  • blocking of a word in a sentence, as if the next word will not come out.

Stuttering is accentuated in the case of excitement or stress. It is less severe or sometimes non-existent when the patient is confident or when he sings or shouts.


The diagnosis of stuttering is often made by the family of the individual, upon recognizing the symptoms mentioned above during the first years of speech. Confirmation is made by a doctor or therapist in the most doubtful cases. No further examination is needed to confirm this.


To treat stuttering, the patient is helped by a speech therapist. This specialist works with speech and gives valuable advice to parents to help reduce their child's stuttering. At a more advanced age, support by a speech therapist may be accompanied by psychological or psychoanalytic support looking for a psychological cause stuttering.


Stuttering cannot be prevented. However, it seems that a child with a parent who stutters is more likely to have a stutter.
