[Aphasic-type language disorders associated with lesions of the putamen and caudate nucleus: clinicopathological findings in one case (author's transl)].

Language disorders developed in a patient following a subcortical infarct involving the left putamen and caudate nucleus. Language was abundant and fluent, with many perseverations, semantic and ideation incoherences, and all activities concerned with verbal or non-verbal expression were affected. Lesions were present in the head and body of the caudate nucleus, the whole of the putamen, the anterior nucleus of the thalamus and the superior part of the internal capsule. The disorder was unique in relation to disturbances of the aphasic type observed in extensive thalamic lesions, or in transcortical sensorial aphasia. Physiopathological interpretation is based on the functional role of the putamen-caudate system in the regulation of many types of behaviour: animal experiments and results of applying stimuli in humans suggests a release of the inhibition exerted by the caudate nucleus on the frontal cortex. Lack of comparable clinicopathological data implies that other similar cases must be reported before the specificity of the disorder can be confirmed.

Research in child language disorders: what do we know and where are we going?

Advances in understanding the nature of language impairment in children over the past decade have been abundant. In this paper, several recurring hypotheses about the nature of the clinical disorder of language impairment in children and underlying etiologies are explored and the ways in which we are moving forward in our understanding of them are considered. Specifically, in the first part, the recent thinking on the nature of specific language impairment as a clinical concept is examined. Characteristics of the population are reviewed and the search for causation is considered. Literature on the relations between language and cognition and between language and social cognition is probed for contributions to our understanding of developmental disorders of language. Two areas in which we have seen marked progress and which hold promise for development in the coming decade are the focus of the second part of the paper. The focal areas are: computer-assisted language sample analyses and neurophysiological contribution to understanding language impairment in children. Thoughts about future directions for work in the area of developmental disorders of language are offered in conclusion.

[Habilitation for handicapped children, mainly for children with visual and hearing impairment, speech-language disorder, and hyperkinetic disorder].

This symposium was focused on habilitation for children with visual and hearing impairment, speech-language disorder, and hyperkinetic disorder. New and variable approaches were reported in topics of habilitation for these handicapped children by an ophthalmologist, an otorhinolaryngologist, a child neurologist, a speech therapist and an educational psychologist. Many points of these approaches were then discussed.

Language disorders in children with autism.

Language development is delayed in most children on the autistic spectrum. The children are dysphasic as well as autistic. Comprehension and pragmatics are invariably affected. Lower level mixed receptive/expressive disorders involve phonological and syntactical processing, whereas higher level processing disorders involve semantics and formulation of discourse. In some children, lower level disorders may be so severe as to preclude speech, whereas in others phonology may be deficient in spontaneous production but not in repetition. Abnormal features of autistic language include aberrant prosody, immediate and delayed echolalia (scripts), and perseveration. Electrophysiological studies indicate that brainstem-evoked potentials are normal. Even in fully verbal individuals with autism, early and late cortical components of auditory, but not visual, event-related potentials are abnormal. Appropriate intervention must address language and behavioral issues. In children with severely defective auditory language, provision of visual language to supplement speech is essential.

The role of the school psychologist in the examination of complex language disorders.

In this article we shall first attempt to show in a summary fashion how the concept of language has changed over the last 20 to 40 years. This will serve as a background and aid to understanding the current view that language disturbances are of such a complex nature that they can only be understood, analysed and treated by means of an interdisciplinary approach. A look at the recent developments in the sciences that touch upon the comprehension of language disturbances elucidates our current view of them. It can help to clarify the role of the psychologist, especially the school psychologist who works with children and adolescents in the diagnosis, counseling, in some cases in the treatment and often in cooperation with other professionals of lingual disturbances. Conclusions can also be drawn as to the specific professional qualifications required and as to the methodology of the psychological examination.

A model for clinical-quantitative classification. Generation I: Application to language-disordered preschool children.

A model is presented for the integration of clinical-inferential and quantitative approaches to classification. In this, the first application of the proposed model, preschool children with developmental language disorders were classified on the basis of clinical interpretations of performance on psychometric subtests. Five hypothesized subgroups were validated on the basis of (a) consensus among five clinical neuropsychologists, (b) language pathologists' reports, (c) comparisons with subgroups defined by a cluster analytic approach, and (d) comparisons among subgroups on variables not used for classification. Results are discussed in terms of the feasibility of the integrated approach, commonalities with other typologies, and the implications of this work to issues of subtype stability, remediation, predictions of later reading achievement, brain-behavior relationships, and generalizability to other clinical groups.

Profiles of children with severe oral language disorders.

The major purpose of this study is to determine whether children assigned to classes for severe oral language handicaps in California by a multidisciplinary diagnostic team exhibit a characteristic ITPA performance profile or a number of distinct profiles. A factor analysis and a cluster analysis was made on the scores of 237 children. It was found that on the factor analysis the results showed a clear auditory-vocal factor and a visual-motor factor. All five tests in the visual-motor channel were superior to the five tests in the auditory-vocal channel. Within the auditory-vocal channel the lowest scores were in auditory association and grammatic closure. Ninety-seven percent of the oral language handicapped children had the lowest scores on these two subtests. It appears from these results that the major deficit of children assigned to severe oral language classes is a deficit in the central organization process, formerly referred to as "central aphasia, or inner language".

A follow-up study of children with articulation and language disorders.

Thirty-six subjects, 18 language-impaired and 18 articulation-impaired children, were followed up with respect to communication skills and educational performance 13 to 20 years after their initial contact with the Speech and Hearing Clinic. According to their parents, nine language-impaired subjects continued to exhibit communication problems as adults, compared to only one of the articulation-impaired subjects. Standardized educational testing conducted while the subjects were in elementary and secondary schools indicated that the language-impaired group consistently achieved at a lower level than the articulation-impaired group, particularly in reading. Differences between the groups were also exhibited in the types of postsecondary education attempted by the subjects. Clinical, educational, and research implications of these results are discussed.

Language disorder--James: a case history.

When James was born he seemed the perfect baby. But gradually Venetia Young became concerned about his slow development. Despite repeated reassurance from health professionals, including her health visitor, she persisted in seeking medical opinion and finally learned that James had a language disorder. Here she describes his early years, the warning signs of his language problem and her battle against the experts' disbelief.

Corpus callosum size in children with developmental language disorder.

Using high-resolution in-vivo magnetic resonance morphometry of the midsagittal area of the corpus callosum (CC) and four callosal subareas in 21 children with developmental language disorder (DLD) of the phonologic-syntactic type we found no significant anatomical differences in comparison to an age- and gender-matched normal control group. There was also no significant between-group difference when the approximately 7% smaller forebrain volume among children with DLD was accounted for by relating CC measures to forebrain volume. Only a tendency towards a larger anterior and middle CC in relation to forebrain volume was found in DLD children. In our DLD children we found the same relationship between CC midsagittal size and forebrain volume as recently reported for normal adults, namely, that the CC area increases to the two-third power of forebrain volume.

Technology applications in intervention for preschool-age children with language disorders.

Preschool-age children are capable of using computers and benefiting from developmentally appropriate software. Computer technology has been used successfully in therapy for young children with speech and language disorders; however, the clinician is a crucial factor in such success. Clinicians choose communication goals and appropriate software, plan precomputer activities, provide appropriate models and opportunities during the computer activity, and provide postcomputer activities that ensure the generalization of new skills. In this article, we discuss and illustrate the characteristics of developmentally appropriate computer-based activities and the role of clinicians in planning and implementing these activities for young children.

A treatable language disorder: pharmacological treatment of pervasive developmental disorder.

Results of treatment of four patients are described. All of the patients had pervasive developmental disorder (PDD), a tic disorder, and a characteristic pattern of speech and language impairment. The patients were treated with haloperidol for their tic disorders, and concomitant with the reduction of the frequency and severity of tics was marked improvement in language. The patients averaged 3 months of language gain for each week of speech therapy directly after the initiation of haloperidol treatment for tics. Progress in speech and language therapy was extremely slow during the years prior to treatment with haloperidol. To the authors' knowledge, no language disorder has been described in the literature which shows such a predictable and marked response to pharmacological treatment. The authors hypothesize that tic disorders in individuals with PDD may be a marker for a more positive response to dopamine antagonists like haloperidol.

Treatment research in speech, language and swallowing: lessons from child language disorders.

Three major types of treatment research methodologies are described. Studies on child language intervention are reviewed as examples of trends and methodological issues characterizing treatment research in speech, language, and swallowing within the last 2-3 decades. Principles are drawn from that literature and suggestions for future directions are discussed with particular attention to recent efforts to support clinical trials and treatment outcomes research.

A minority perspective in the diagnosis of child language disorders.

The effective diagnosis and treatment of persons from diverse minority language backgrounds has become an important issue in the field of speech and language pathology. Yet, many SLPs have had little or no formal training in minority language, there is a paucity of normative data on language acquisition in minority groups, and there are few standardized speech and language tests appropriate for these groups. We described a diagnostic process that addresses these problems. The diagnostic protocol we have proposed for a child from a Black English-speaking background characterizes many of the major issues in treating minority children. In summary, we proposed four assessment strategies: gathering referral source data; making direct observations; using standardized tests of non-speech and language behavior (cognition, perception, motor, etc.); and eliciting language samples and probes.
