Stuttering sub-types

Developmental
Stuttering is typically a developmental disorder beginning in early childhood and continuing into adulthood at least 20% of children of those affected. The mean onset of stuttering is 30 months. Although there is variability, early stuttering behaviours usually consist of word or syllable repetitions, and secondary behaviours such as tension, avoidance or escape behaviours are absent. Most young children are unaware of the interruptions in their speech. With early stutterers, disfluency may to be episodic, and periods of stuttering are followed by periods of relative fluency. Though the rate of early recovery is very high, with time a young stutterer may transition from easy, relaxed repetition to more tense and effortful stuttering, including blocks and prolongations. Some propose that parental reaction may affect the development of chronic stutter. Recommendations to slow down, take a breath, say it again, etc may increase the child’s anxiety and fear, leading to more difficulties with speaking and, in the “cycle of stuttering” to ever yet more fear, anxiety and expectation of stuttering. With time secondary stuttering including escape behaviours such eye blinking, lip movements, etc. may be used, as well as fear and avoidance of sounds, words, people, or speaking situations. Eventually, many become fully aware of their disorder and begin to identify themselves as "stutterers." With this may come deeper frustration, embarrassment and shame. Other, rarer, pattern of stuttering development have been described, including sudden onset with the child being unable to speak, despite attempts to do so. The child usually blocks silently of the first sound of a sentence, and shows high levels of awareness and frustration. Another variety also begins suddenly with frequent word and phrase repetition, and do not develop secondary stuttering behaviours.
Acquired
In rare cases, stuttering may be acquired in adulthood as the result of a neurological event such as a head injury, tumour, stroke or drug abuse/misuse. The stuttering has different characteristics from its developmental equivalent: it tends to be limited to part-word or sound repetitions, and is associated with a relative lack of anxiety and secondary stuttering behaviors. Techniques such as altered auditory feedback (see below) which may promote fluency in stutterers with the developmental condition, are not effective with the acquired type.
Psychogenic stuttering may also arise after a traumatic experience such as a bereavement, the breakup of a relationship or as the psychological reaction to physical trauma. Its symptoms tend to be homogeneous: the stuttering is of sudden onset and associated with a significant events, it is constant and uninfluenced that different speaking situations, and there is initial little awareness or concern shown by the speaker in their speech.
