Evidence of nonverbal learning disability among learning disabled boys with sensory integrative dysfunction.

The presumed sensorimotor basis of the nonverbal learning disability syndrome was investigated among 90 learning disabled boys (M age = 6 yr., 8 mo., SD = 12.2 mo.) with sensory integrative dysfunction. The majority of the boys were Caucasian, lower to middle socioeconomic status, and from urban, English-speaking families. 14% (n = 13) of the boys satisfied core discrepancy criteria for nonverbal learning disability, including both a significantly higher Wechsler Verbal than Performance IQ and a higher standard score in Reading than Arithmetic on the Wide Range Achievement Test. Compared with a control group of 19 boys from the same sample who had no significant discrepancies, boys with nonverbal learning disability had significantly greater weaknesses in space visualization and visuomotor coordination. As predicted, rote verbal memory and syntactical strengths were also exhibited by boys with nonverbal learning disability, but the two groups did not differ significantly.

Learning disability.

Learning disability is common, affecting 1-2.5% of the general population in the Western world, and encompasses many different conditions. It usually leads to major functional impairment and lifelong need for support and interventions, not the least important of which are medical and health-care services. Rapid progress is being made in the understanding of the cause and pathogenesis of many learning disability syndromes, and these advances are likely to improve targeted interventions in the next decade. Many countries have abolished a learning disability specialty for medical professionals, but there is a great need to revive this niche of medical knowledge. We know little about quality of life and effects on families of people with learning disability, and research is needed to address these issues.

Approach to learning disability.

Learning disabilities (LD) is one of the important causes of poor academic performance in school going children. Learning disabilities are developmental disorders that usually manifest during the period of normal education. These disabilities create a significant gap between the true potential and day to day performance of an individual. Dyslexia, dysgraphia and dyscalculia denote the problem related to reading, writing and mathematics. Perinatal problems are certain neurological conditions, known to be associated with LD; however, genetic predisposition seems to be the most probable etiological factors. Evaluation of a child suspected to be having LD consists of medical examination, vision and hearing test analysis of school performance. The psycho-behaviour assessment and education testing are essential in the process of diagnosis. The experienced persons in the field of LD should interpret the results of such tests. With Individualized Remedial Education Plan (IEP) most children learn to cope up with disability and may get integrated in a regular steam.

Exercise programmes in the treatment of children with learning disabilities.

Learning disability is characterised by a discrepancy between achievement and assessed intellectual ability. Children with this problem commonly (but not invariably) show impaired motor proficiency, as assessed by such instruments as the Bruininks-Oseretsky Test of motor proficiency. It has been hypothesised that poor motor performance and/or poor social skills lead to exclusion from games, creating a vicious cycle of decreasing participation, decreasing competence, a deterioration of self-worth and increasing social maladjustment. Attempts to break the vicious cycle with programmes designed to enhance motor proficiency have been uniformly unsuccessful. There is limited experimental evidence to support the view that structured physical activity programmes with an embedded social skills training component can be an effective method of enhancing both actual motor ability and self-perception of physical and academic competence. However, a controlled comparison with small-group, academic instruction has shown that, from the educational perspective, a physical activity-based intervention is no more effective than other forms of special attention. The main argument for delivering social skills training through a physical activity programme lies not in a unique impact upon learning disability, but rather in terms of the other well-established long term health benefits of exercise.

Learning disabilities and learned helplessness: a heuristic approach.

This study investigated whether students with learning disabilities exhibited learned helpless behavior at a greater rate than their normal achieving peers when confronted with reading failure. Forty-five third grade students from a suburban elementary schools were participants in the study. Thirty of the subjects were classified as having a learning disability (LD) and the remaining 15 subjects were from regular education (RE) classrooms. Fifteen of the students with LD were placed in the treatment group and the remaining fifteen were placed in the control group. All the regular education students were placed in the treatment group. After randomly assigning the students with LD into either a treatment (stressed) group or a control (nonstressed) group, the stressed students were administered a reading instrument in order to measure how they dealt with failure. A one-way ANCOVA was conducted to determine whether significant differences existed between the groups based on their posttest scores. The results indicate that stressed students with LD have a significantly more difficult time recovering from stress than their regular education peers.

Referential communication abilities of learning-disabled, language-learning-disabled, and normal school-age children.

Past research in referential communication has indicated normally developing children show developmental progression in ability to communicate a specific referent to a listener. In one paradigm subjects were given lists of word-pairs in which one member of each pair was designated as the referent. It was shown that communicating about referents found in word-pairs associated in some way was more difficult than communicating about referents in dissimilar word-pairs. The present study extended this methodology to learning-disabled children. Learning-disabled, language-learning-disabled, and normally achieving children were asked to communicate about 30 pictured referents on three different tasks. On Tasks 1 and 2 each subject was asked to give a clue for the referent that would distinguish it from the other picture. Stimuli for Task 1 were 30 pairs of pictures that were related in some way and the stimuli for Task 2 were 30 pairs of unrelated pictures. Task 3 required the subjects to evaluate the adequacy of the examiner's clues for Task 1 stimuli. The disabled subjects were matched to the normally achieving subjects on the basis of receptive vocabulary age. Few differences were noted among the groups' performances on these referential communication tasks. Implications include the importance of vocabulary and concept development to referential communication.

[Neurological assessment for learning disability].

Learning disabilities present a diagnostic and therapeutic management challenge that requires an interdisciplinary approach initiated and coordinated by the child neurologist. An optimal evaluation for these conditions must include an extensive knowledge of the types and range of these disorders, a complete neurological and laboratory examination, a neuropsychological assessment tailored to the individual needs of the patient, a speech pathological evaluation when pertinent, and special attention to the frequent co-occurrence of more than one condition susceptible of interfering with learning.

Neurobiology of learning disabilities.

Learning disabilities are the product of neurological damage which occurs during fetal development. The malformations produced are unique to each individual and do not resemble acquired neurological damage. Consequently, models of developmental disorders must be developed independently and cannot be based on acquired adult aphasia or dyslexia literature. Neurological conditions of adults with developmental disorders are difficult to interpret since aberrations that occur early during fetal development can have a cascading effect, disrupting neural organization in other brain regions. An appreciation of basic concepts of brain development suggests treatment interventions that will modify neurophysiological functioning.

The prevalence of depressive symptoms in children with learning disabilities.

Learning difficulties have been considered to be a symptom of childhood depression by some authors, whereas others have examined depression as a cause of cognitive difficulties, including learning disabilities (LD). This study examined the prevalence of depressive symptoms in a sample of public school elementary children aged 8 through 11, 37 boys and 16 girls, identified as LD by state standards. Of the sample of 53 children, 35.85% scored in the depressed range on the Children's Depression Inventory. Comparison of the children's self-reports and parents' reports of depressive symptoms in their children was not significant. Implications of the results are discussed relative to the role of school personnel and the assessment process in recognizing depressive symptoms in students with LD.

Validation of a Questionnaire to Screen University Students for Learning Disabilities.

Learning disabilities (LD) may cause academic failures among university students, but minor accommodations may in some instances allow students to progress satisfactorily. The current study validates a questionnaire for detecting students likely to have an LD. University students, 57 with a documented LD and 134 without, completed a Likert-scale questionnaire to assess the degree of self-perceived difficulty for 50 learning or testing situations. Wilcoxon rank sum test, separate logistic regression models, and determination of the best joint set of predictors of LD were carried out. The mean per-item questionnaire score was higher in the LD group (p < 0.0001); 47 individual items were significant predictors (i.e., p < 0.05) of LD status. The best joint set of predictors consisted of items dealing with word pronunciation, comprehending mathematical word problems, formulating summaries, spelling, slow reading rate, finishing tests in the allotted time, note-taking in lectures, and falling asleep while reading. Incorporating responses to these eight items, a formula was derived to determine the probability of LD. Taking 0.26 as the threshold for predicting the presence of an LD, the sensitivity of the questionnaire was 88%, the specificity was 87% for this population. The questionnaire could be an effective screening tool to detect university or professional students who should consider comprehensive testing for LD.

Antipsychotic medication for those with both schizophrenia and learning disability.

BACKGROUND: Antipsychotic medication is the standard treatment for people with learning disability and schizophrenia. OBJECTIVES: To determine the efficacy of any antipsychotic medication for treating people with a dual diagnosis of learning disability and schizophrenia. SEARCH STRATEGY: Electronic searching of Biological Abstracts, the Cochrane Schizophrenia Group's Register of trials, the Cochrane Library, EMBASE, PsycLIT and MEDLINE. Unpublished data were sought from pharmaceutical companies. Both authors independently selected the relevant studies from the reports identified in this way. SELECTION CRITERIA: 1. All randomised controlled trials of antipsychotic medication, regardless of dosage, versus a placebo control, of longer than one month's duration. 2. Anyone over 18 years of age with both learning disability and schizophrenia. Learning disability was defined as a measured IQ of 70 or less. Any mode of diagnosis of schizophrenia was acceptable. DATA COLLECTION AND ANALYSIS: The two reviewers independently attempted to select and then extract data but it was not possible to do this with the single study that met the inclusion criteria. MAIN RESULTS: Only one relevant randomised trial was found by the searches. This study included four people with a dual diagnosis of schizophrenia and learning disability, but results were available for only two. The groups to which the other two people were allocated were unclear. In order to display the data, too many assumptions would have to have been made about these other two people and any results would be uninformative and potentially misleading. REVIEWER'S CONCLUSIONS: Using the methods described the reviewers found no randomised controlled trial evidence to guide the use of antipsychotic medication for those with both learning disability and schizophrenia. Until the urgent need for randomised controlled trials is met clinical practice will continue to be guided by extrapolation of evidence from randomised controlled trials involving people with schizophrenia but without learning disability and non-randomised trials of those with learning disability and schizophrenia.

Health screening for people with learning disabilities by a community learning disability nursing service in Northern Ireland.

Over the last 30 years there has been a considerable increase in the life expectancy of people with learning disabilities. This has resulted in changing patterns of morbidity and mortality and an increasing recognition of the health needs of people with learning disabilities. Major strides forward have been made in the reduction of preventable illnesses among the general population. However, among people with learning disabilities such illnesses have received only limited health promotion attention until recently. In the last decade major gaps have been identified in the ability of current primary health services to respond to the needs of people with learning disabilities. The need to respond effectively to this situation has been identified as a priority by the current United Kingdom Government. Following an overview of the literature in relation to the changing health profile of people with learning disabilities and the need for health screening, consideration is given to some of the key difficulties which may be encountered when attempting to utilize current primary health services. The analysis of data derived from the health screening of 373 people with learning disabilities by a community nursing service in Down and Lisburn Health and Social Services Trust reveals the need for further action in relation to cardiovascular status, sensory deficits, mobility and aspects of sexual health.

Differential performance of learning disabled and non-learning disabled children on the McCarthy scales, WISC-R, and WRAT.

Individually administered the McCarthy Scales of Children's Abilities, WISC-R, and WRAT to 30 learning disabled and 30 non-learning disabled second-grade students. The McCarthy General Cognitive Index and the WISC-R Full Scale IQ scores were compared for both groups. In addition, correlations between the General Cognitive Index, WISC-R IQ, and mean WRAT achievement were reported. There was marginal support for previous studies that suggested that the McCarthy Scales are more consistent with the academic functioning of learning disable students. Implications and directions for future research were discussed.

A homogeneous group of persons with learning disabilities: adults with severe learning disabilities in vocational rehabilitation.

The results of a comprehensive psychoeducational assessment of adults having learning disabilities (LD) and participating in vocational rehabilitation are presented. The subjects were found to have low-average general intelligence; lower verbal than performance IQs; attention, reasoning, and auditory memory deficits; academic achievement at the fourth-/fifth-grade level; language problems; and low self-esteem. These results were contrasted with other studies of adults with LD in vocational rehabilitation, and all studies on this population reported similar findings. A comparison of studies of adults with LD who were clients of vocational rehabilitation with those in college or employed and with those who had been labeled as learning disabled in childhood indicated that the adults with LD in vocational rehabilitation seem to constitute a homogeneous group of persons with severe deficits. The need to subtype learning disabilities by severity and criteria for making such determinations are proposed.

How children with neurofibromatosis type 1 differ from "typical" learning disabled clinic attenders: nonverbal learning disabilities revisited.

To further investigate cognitive deficits in children with Neurofibromatosis Type 1 (NF-1), children with NF-1 were compared to typical learning disabled clinic attenders (LD-clinic), all of whom had reading disabilities, as well as to a group with no disabilities (NoDx). Results indicated that both the NF-1 group and LD-clinic group had reading and reading-related deficits when compared to the NoDx group; however, the NF-1 group was more globally language impaired than the LD-clinic group. In addition, the NF-1 group scored significantly lower than the LD-clinic group, but not the NoDx group, on the visuospatial measures, thus confirming that children with NF-1 have visuospatial deficits not typical of a general LD-clinic population. The NF-1 group was not impaired in comparison to the NoDx group on certain language and visuospatial tasks that were previously found to be deficits in sibling pairwise matched designs; thus, the importance of considering genetic and familial context when studying the impact of genetic disorders on cognition was demonstrated.
