A stammer is a fluency disorder which can affect both adults and children. In adults, it is usually something which they have developed at a younger age, however not always. A stammer affects the smooth timing and flowing of speech through disruptions and stops in speech flow.

What is a stammer?

A stammer is a disturbance in fluency which affects the smooth flow and the timing of speech. Stammers can either be a stop in speech flow or a disturbance. Stops tend to be repetitions of sounds, words or syllables. Sounds may also be prolonged. An individual who stammers may appear to have tense or jerky speech. They may also have developed avoidance techniques for certain words or situations within which they know will be difficult for them. The type of stutter someone has will depend upon the individual and their circumstances and triggers.

What different types of stammer are there?

There are many different types of stammer and severity will depend upon the individual and what type of stammer they have. Some of the most common forms of stammer are listed below:


This occurs in children at a young age when they are developing speech usually around the ages of 1-4years.


Brain and nerve signal problems.


Thought and reasoning areas of the brain is where it starts and is commonly found in people who suffer from mental illness, excessive stress or have been subjected to a lot of distress.

Normal non-fluency- this is not a stammer and is a normal developmental process which children go through around the age of 4 years old. Children become disfluent as they are learning language at a rapid rate and sometimes their speech cannot catch up with their brain. This will often result in them repeating the same word over and over, when they are trying to tell you something. For example: and then, and then, and then I went to the park.

What causes stammering?

The exact cause of stammering is unknown however research has shown that genetic factors may influence whether an individual stammers or not. Therefore if someone has a relative that stammers they may be more susceptible to stammering. However, stammering could also be caused by brain injury that has damaged certain areas of the speech output region of the brain.

How does stammering affect people?

Stammering can range from mild to severe and will very much depend upon the individual as to how it will affect a person in their everyday life. It will also depend upon the situation the individual is in, and may change depending on the level of stress.

Although stammering affects speech, it is a serious communication problem as it can affect an individual's confidence and self-esteem. This can then have an effect on an individual's relationships with other people and can also affect their work and education.
