Discourse after Early-Onset Hydrocephalus: Core Deficits in Children of Average Intelligence

  title={Discourse after Early-Onset Hydrocephalus: Core Deficits in Children of Average Intelligence},
  author={Marcia A. Barnes and Maureen Dennis},
  journal={Brain and Language},
A review of our studies of oral and written language in children with early-onset hydrocephalus suggests that hydrocephalus is associated with specific deficits in discourse as opposed to generalized linguistic deficit. It is proposed that the language skills that are impaired in hydrocephalus are those that require context to derive meaning, while those that are intact may function relatively independent of particular discourse contexts. This hypothesis was tested in two discourse studies… 
Pragmatic ability in children with early onset brain damage and children with pragmatic language impairnent
The children with CP and the children with SBH represented in this thesis both have pragmatically related problems, which occur mainly in relation to higher-level language skills as narrative ability, and are mainly manifested at a textual level.

    Child neuropsychology : a journal on normal and abnormal development in childhood and adolescence
  • 2001
This review summarizes the current knowledge about neurocognitive sequelae of hydrocephalus and recommends further investigations into these effects to help clinicians and researchers interested in the impact of diffuse neurophysiological damage on cognition in the developing brain.
Poor Reading Comprehension Despite Fast Word Decoding in Children with Hydrocephalus
The children with hydrocephalus were as fast as controls in reading words, but, unlike controls, they did not demonstrate an effect of spelling-sound regularity, and decoding speed did not contribute to reading comprehension beyond word decoding accuracy.
Meaning construction and integration in children with hydrocephalus
Cognitive functions in children with myelomeningocele without hydrocephalus
Hydrocephalus rather than MMC in itself appeared to cause the cognitive deficits found in children with MMC, and those with only MMC performed just as well as the controls.
Narrative Skills in Children with Spina Bifida and Hydrocephalus

A model of comprehension in spina bifida meningomyelocele: Meaning activation, integration, and revision
Compared to age peers, children with SBM did not construct situation models that required integration of information across sentences, even though they could construct such models from single sentences.
Mathematics skills in good readers with hydrocephalus
Computation deficits in children with hydrocephalus reflect delayed development of procedural knowledge, and problems in specific math domains such as geometry and applied math, were associated with deficits in constituent cognitive skills such as visual spatial competence, memory, and general knowledge.


Oral discourse after early-onset hydrocephalus: linguistic ambiguity, figurative language, speech acts, and script-based inferences.
The fluent, grammatically framed, but content-impoverished language described in early-onset hydrocephalus appears to reflect not so much problems in deriving word- and sentence-based meaning as deficits in the pragmatic use and understanding of language in discourse.
The Content of Narrative Discourse in Children and Adolescents after Early-Onset Hydrocephalus and in Normally Developing Age Peers
By showing impaired textual rhetoric coexisting with apparently preserved interpersonal rhetoric in individuals with developmental anomalies of brain development, the present data provide some support for a functional dissociation between the two classes of pragmatic constraints.
Language of hydrocephalic children and adolescents.
The results revealed a limited resilience of language to the effects of early hydrocephalus, and hydrocephalics were either less skilled or less able to maintain age-appropriate skill mastery than normal peers within particular language domains.
Reading in children and adolescents after early onset hydrocephalus and in normally developing age peers: phonological analysis, word recognition, word comprehension, and passage comprehension skill.
It is shown that adequate levels of word recognition, at least as measured by accuracy, in children with early hydrocephalus coexist with a significant deficit in reading comprehension.
Cerebral white matter and cognition in hydrocephalic children.
A relationship between the corpus callosum and cognitive skills that is also influenced by hydrocephalus-related changes in the lateral ventricles and other cerebral white-matter tracts is shown.

The "cocktail party syndrome" in children with hydrocephalus and spina bifida.

Assessment at the age of seven revealed children with the cocktail party syndrome to be significantly poorer than other cases of spina bifida in reading, spelling, arithmetic, and they had shorter concentration spans and slightly more behaviour problems in school according to their teachers.
Syntactically Based Sentence Processing Classes: Evidence from Event-Related Brain Potentials
The distinct timing and distribution of these effects provide biological support for theories that distinguish between these types of grammatical rules and constraints and more generally for the proposal that semantic and grammatical processes are distinct subsystems within the language faculty.
