Cluttering, neurogenic stuttering and disfluency in children with language difficulties
Not every disfluency is developmental stuttering: in cluttering speech is fast or irregular and awareness is low; neurogenic stuttering appears after brain damage, anywhere in the word and without fear or secondary behaviours; and in children with language difficulties disfluency comes mainly from word-retrieval difficulty.
Why it matters in the exam
Exam questions present a person in his thirties or sixties who recently began stuttering, after an accident or stroke, with word-retrieval and writing difficulties, and ask for the likely diagnosis (acquired or neurogenic stuttering). A reverse question asks which finding does not support a neurogenic diagnosis — for example stuttering mainly on content words, which is in fact a pattern of developmental stuttering.
For cluttering you are asked what characterises it: a fast or irregular rate, many disfluencies resembling normal disfluency, "swallowed" syllables and low awareness, compared with high awareness in stuttering. In treating cluttering the work is on rate control and self-monitoring, and increasing eye contact with the listener helps the speaker notice when he was not understood. In children with language difficulties disfluency is mainly OD rather than SLD.
Key points
- Cluttering: fast or irregular rate, low awareness.
- Neurogenic: onset in adulthood after damage, anywhere in the word, without fear.
- Developmental: word starts and content words, awareness and adaptation.
- Children with language difficulties: OD more than SLD, because of retrieval.
- Eye contact in cluttering treatment helps monitor the listener.
Summary table
| Condition | Features | What sets it apart | Treatment or note |
|---|---|---|---|
| Cluttering | Fast or irregular rate, swallowed syllables, disfluency resembling normal disfluency | Low awareness of the problem | Rate control, self-monitoring, eye contact with the listener |
| Neurogenic stuttering | Appears after stroke, head injury or neurological disease in adulthood | Disfluency anywhere in the word, also on function words; no adaptation; little fear and few secondary behaviours | Neurological assessment; sometimes together with aphasia |
| Psychogenic stuttering | Sudden onset after an emotional event | Atypical patterns, sometimes rapid change | Referral and collaboration with other professionals |
| Disfluency in children with language difficulties | Phrase repetitions, revisions, fillers | Mainly OD rather than SLD; linked to word retrieval | Language treatment |
| Developmental stuttering (for comparison) | Begins in childhood, at word starts and on content words | High awareness, adaptation, secondary behaviours | The usual stuttering treatment approaches |
