Developmental neurogenic non-syndromal cluttering – http://id.who.int/icd/entity/616505365

Developmental speech fluency disorder which arises during childhood without recognizable environmental causes, is outside the limits of normal variation expected for age and level of intellectual functioning, and is paralleled by structural and functional cerebral anomalies. This type of cluttering is usually labelled just "cluttering". It is characterised by persistent and frequent or pervasive disruption of the rhythmic flow of speech (clutter-typical symptoms) that is untypical for stuttering. It impairs communication and intelligibility. Clutter-typical symptoms are a higher than normal or irregular speech tempo, or both, violations of word and sentence structures with phonological abnormalities, confluence or omission of syllables, unusual pauses, abnormal syllable accent or unusual speech rhythm, and difficulties to maintain normal patterns of sounds, syllables, phrases, or pauses.
