Separating attention deficit hyperactivity disorder and learning disabilities in girls: a familial risk analysis.

OBJECTIVE: Familial risk analysis was used to clarify the relationship in girls between attention deficit hyperactivity disorder (ADHD) and learning disabilities in either mathematics or reading. METHOD: The authors assessed the presence of ADHD and learning disabilities in 679 first-degree relatives of three groups of index children: girls with ADHD and a comorbid learning disability, girls with ADHD but no learning disabilities, and a comparison group of girls without ADHD. RESULTS: The risk for ADHD was similarly higher in families of ADHD probands with and without learning disabilities; both groups had significantly higher rates of ADHD than did families of the comparison girls. In contrast, only among relatives of ADHD probands with a learning disability was there a higher risk for learning disabilities. A strong (although statistically nonsignificant) difference emerged that suggested at least some degree of cosegregation of ADHD and learning disabilities in family members. There was no evidence of nonrandom mating between spouses with ADHD and learning disabilities. CONCLUSIONS: These results extend previously reported findings regarding the relationship of ADHD and learning disabilities to female subjects and raise the possibility that, in girls, the relationship between ADHD and learning disabilities is due to shared familial risk factors.

Nonverbal social interaction skills of children with learning disabilities.

Many children with learning disabilities (LD) face problems in their nonverbal communication, which constitutes an important component of their social skills. This study explores the frequency of nonverbal initiations and responses of 36 children with LD and 36 children without LD matched for age and gender, who were observed for 40 min during the break. Younger and older children with and without LD did not differ significantly in their nonverbal responses, but there was a statistically significant difference in terms of younger children's nonverbal initiations. Younger children with LD exhibited significantly fewer nonverbal initiations than younger children without LD. Findings are discussed and suggestions are made for further research.

A German perspective on learning disabilities.

German practices in the field of learning disabilities beyond preschool level are described in the context of their historical formation. In a historical perspective it becomes obvious that the German notion of Lernbehinderung, although being just a translation of "learning disabilities," differs markedly from the American definition. Definitional problems, educational practices, and emerging trends in the German field of "learning disabilities" are discussed.

Idiopathic learning disability and genome imbalance.

Learning disability (LD) is a very common, lifelong and disabling condition, affecting about 3% of the population. Despite this, it is only over the past 10-15 years that major progress has been made towards understanding the origins of LD. In particular, genetics driven advances in technology have led to the unequivocal demonstration of the importance of genome imbalance in the aetiology of idiopathic LD (ILD). In this review we provide an overview of these advances, discussing technologies such as multi-telomere FISH and array CGH that have already emerged as well as new approaches that show diagnostic potential for the future. The advances to date have highlighted new considerations such as copy number polymorphisms (CNPs) that can complicate the interpretation of genome imbalance and its relevance to ILD. More importantly though, they have provided a remarkable approximately 15-20% improvement in diagnostic capability as well as facilitating genotype/phenotype correlations and providing new avenues for the identification and understanding of genes involved in neurocognitive function.

Assessing dementia in people with learning disabilities: the relationship between two screening measures.

As life expectancy increases for people with learning disabilities, the impact of dementia on people with learning disabilities and their families, carers and services is becoming more apparent. Psychological services for learning disabilities are receiving an increasing number of referrals requesting dementia assessment. Health and social care services are adapting to the diverse needs of an ageing population with learning disabilities. This article describes a study investigating the relationship between two assessments for dementia in people with learning disabilities. Carers of people with learning disabilities over the age of 50 (or 40 if the individual had Down syndrome) completed the Dementia Questionnaire for Mentally Retarded People and the Adaptive Behaviour Scale--Residential and Community. Overall, the two questionnaire measures showed significant relationships. However, results suggested that both assessments have clinical value in informing individual needs and aiding diagnosis. Implications for both clinical and social care services are discussed.

Cognitive impulsivity in specific learning disabilities.

Many studies on cognitive impulsivity in learning disabled children have been criticized for their methodological limitations, and they have not dealt with the different types of learning disability. The aim of this study was to overcome these limitations and to assess if there was a significant cognitive impulsivity in reading disorder and/or spelling disorder by using the 20-item Matching Familiar Figures Test (MFF20). A total of 110 children (second through eighth grades) were recruited from a cohort of children assessed for the first time in a National Health clinic specialized in the study of specific learning disabilities. In all, 30 dyslexic children and 25 children with spelling disorder (all children without an ADHD comorbidity) were compared with 55 children of a control group on the MMF20 (accuracy and time latency). Results showed that the children with reading disorder were less accurate than the children with spelling disability (p<0.05). Both these groups performed less accurately than the control group. Subjects with dyslexia were faster than both the other groups in response time (p<0.05), clearly showing a significantly higher cognitive impulsivity than the other groups. Hence, data seem to confirm the idea that, similar to ADHD children, dyslexic children have impaired frontal/prefrontal functions. Clinical and treatment implications are discussed.

Epidemiology of psychiatric disorders in elderly compared with younger adults with learning disabilities.

BACKGROUND: The literature regarding psychiatric illness among elderly people with learning disabilities is limited and conflicting because of methodological differences. There have been no recent studies comparing psychiatric epidemiology between younger and older adults with learning disabilities, using the same methodology and definitions. METHOD: Comprehensive psychiatric examination using a semi-structured rating scale was undertaken on everyone with learning disabilities, aged 65 years or over (n = 134), living in a defined geographical area. Comparison was made with a randomly selected control group of adults with learning disabilities aged 20-65 years (n = 73) drawn from the same geographical area. RESULTS: Elderly people with learning disabilities have a greater prevalence of psychiatric morbidity than younger controls (68.7 v. 47.9%). Rates for depression and anxiety disorders are high, and dementia is common: there are equal rates for schizophrenia/delusional disorders, autism and behaviour disorders in the two groups. CONCLUSIONS: The higher psychiatric morbidity among elderly (compared with younger) people with learning disabilities has not previously received adequate recognition. This warrants further investigation by service planners and clinicians.

Test of the definition of learning disability based on the difference between IQ and achievement.

A learning disability is commonly defined as a discrepancy between IQ and achievement. This has been criticized for identifying too many children as having a learning disability who have high IQs and average academic achievement. Such overidentification as actually occurred was assessed in 473 referred children (8-16 years, M= 10, SD=2) with normal intelligence. Learning disability was defined as a significant discrepancy (p<.05) between predicted and obtained achievement in reading, mathematics, or written expression on the Wechsler Individual Achievement Test. Predicted achievement was based on the child's WISC-III Full Scale IQ. Overidentification was considered to occur when a child scored at or above age level in reading, mathematics, and writing but still had a significant discrepancy between predicted and obtained achievement by virtue of a high IQ. Learning disability was diagnosed in 312 (66%) of the children. There was no overidentification because all children had one or more WIAT scores below the normative level for their age, i.e., < 100. Further, only 7% of the children were identified with a learning disability based on a WIAT score in the 90s. These children had a mean IQ of 123 and were rated by their teachers and parents as having learning problems.

Mental retardation and learning disabilities: conceptual and applied issues.

The relationship between mental retardation and learning disabilities is clouded by conceptual issues and current practices in applied (i.e., educational and noneducational) settings. In this article, we initially discuss whether mental retardation can be considered a concomitant disability associated with learning disabilities or whether these two disabilities are mutually exclusive categories. Conceptual issues related to this question are then reviewed to provide a perspective for viewing these two traditional areas of exceptionality. Emerging areas of concern in term of definition, classification, etiology, and lifelong issues are addressed. Attention is then given to applied issues that have a direct effect on the lives of individuals with disabilities. Specific topics include educational curricula, instruction, inclusion, and adult services and supports.

The genetics of learning disabilities.

Rapid progress in the study of learning disabilities requires a common context within which investigators and professionals with very diverse backgrounds can work towards common goals. Much evidence points to the heterogeneity of origin and clinical expression of learning disabilities as well as to many other ways in which they resemble such multifactorial conditions as mental retardation, gout and hypertension. In these conditions, genetic and epidemiological methods have been used to sort out the constitutional and environmental factors which precipitate disease in susceptible persons. Such an approach to learning disabilities can be expected to be rewarding.

A rapid screening measure for the identification of visuospatial learning disability in schools.

Verbal and nonverbal forms of developmental learning disabilities have been reported. Whereas there are several instruments for evaluating children for the presence of verbal learning disabilities at school, no screening tool is available to identify children who have nonverbal learning disabilities. This study aimed at devising and validating a short screening questionnaire that can be used by teachers in primary schools to identify those children who need to be referred for clinical services because they have a visuospatial learning disability (VSLD). An 18-item Shortened Visuospatial Questionnaire (SVS) was derived from an earlier, longer version. Its validation procedure was twofold and was achieved by (a) verifying that children who had been identified with the SVS questionnaire as having a VSLD actually showed visuospatial deficits on psychometric evaluation and by (b) rating with the SVS a clinically identified population of children with VSLD. The results of the validation procedure showed that the SVS is a quick, reliable, and valid instrument that may be helpful in identifying children with VSLD in primary school.

A categorical analysis of the social attributions of learning-disabled children.

The social attributions of learning-disabled and control children with either similar or higher social acceptance ratings were assessed within an open-ended interview format. In addition, measures of social self-esteem and expectation of social success were obtained. The learning-disabled group used luck more frequently and personality interaction less frequently as explanations for social outcomes than did the other two groups. Learning-disabled children also had the lowest expectation of social success and, like the low acceptance group, had a poorer social self-image. Possible explanations for the development of these attributions and the implications for holding them were discussed.

Learning disabilities and the college student: identification and diagnosis.

The identification and diagnosis of a learning disability in the college student are complex tasks. They constitute important tasks when we realize that 720,000 college students (6 percent, if we assume that there are 12 million in college today) may be learning disabled ( Astin 1983). It is evident that children with learning disabilities are at risk for psychological and social problems in adolescence and young adulthood ( Bellak 1979; Crabtree 1981; Cruikshank et al. 1980; Horowitz 1981). There is a risk that the learning disability will not be identified, and, hence, the problem will be treated as only a psychogenic one. Unfortunately, this will tend to contribute not only to the student's feelings of guilt, stupidity, and inability to change but also to the clinician's sense of frustration. The description of the learning disabled college student and the two-step identification process in this chapter provides guidelines to aid understanding of these issues. Most colleges have not yet come to grips with what it means to have learning disabled students in terms of teaching, academic evaluation, diagnosis, and college counseling. To do so is important not only because of recent laws that guarantee equal educational opportunity for these students but also because a learning disability, whether overt or covert, can profoundly affect a person's educational and psychosocial development. It has often been said that the capacity to love and work is the foundation for the healthy adult. It is easy to see how academic learning is the work of the college student and educational success or failure is linked integrally to self-esteem and self-love.

Discourse processes underlying social competence in children with language learning disabilities.

Children with both a language impairment and a learning disability are at risk for poor social competence. Yet the processes that place these children at risk remain unclear. A developmental-organizational perspective was used to explore processes underlying risk for poor social competence among language learning disable children. To this end, the relative influences of language learning disability and social discourse skills on social competence were examined in 50 language learning disabled (LLD) and 50 control (non-LLD) children aged 8-12 years. Findings indicated that social discourse skills mediated the relation between LLD status and children's social competence. Specifically, a domain of social discourse, figurative language, was the strongest mediator of the effect of LLD status on social competence. Additionally, differences were confirmed between the LLD and non-LLD group in two domains of social discourse, recreating sentences and figurative language, as well as social competence. Two other domains of social discourse, understanding ambiguous sentences and making inferences, did not discriminate the groups. The findings emphasize the importance of analyzing interrelations among domains to identify critical factors related to developmental outcomes.

Social skills deficits as a primary learning disability.

Advances in the definition of social skills deficits in children and youth with learning disabilities are presented and critiqued. The proposed modified definition of learning disability by the Interagency Committee on Learning Disabilities, which includes social skills deficits as a specific learning disability, is presented and discussed. This definition is analyzed from primary, secondary, and social learning theory causative hypotheses. Development of an adequate assessment technology is viewed as critical to the identification and classification of social skills deficits in children and youth with learning disabilities.

Maintenance of oral health in people with learning disabilities.

The oral health of people with learning disabilities is often compromised, which has a deleterious effect on their well-being. This article explores the need for specialist intervention. Barriers to effective care are scrutinised and potential solutions are suggested. As many people with learning disabilities are reliant upon their carers for the maintenance of their oral health, the article concludes with an analysis of advice to carers.

Instructional and curricular requisites of mainstreamed students with learning disabilities.

The successful integration of students with learning disabilities into mainstream reading classes may require teachers to adapt instruction and curricula in major ways. In this article, we discuss the relation between the instruction prescribed by standardized commercial curricula and the reading achievement of mainstreamed students with learning disabilities and other low-performing nonhandicapped students. An instructional template designed to complement commercially published reading lessons is described and its effects on the reading achievement of mainstreamed students with learning disabilities examined. Next, the limitations of generic instructional procedures to rectify the deficiencies of mainstream curricular programs for students with greater-than-average instructional needs are reviewed. We conclude with a discussion of the complexity of educating instructively needy learners in mainstream settings and the significance of well-designed instruction.

Pharmacists' knowledge and attitudes regarding monitoring the behaviors of children with learning disabilities.

The attitudes and knowledge of pharmacists in Nebraska regarding children's learning disabilities were surveyed by questionnaire. One hundred thirty-three pharmacists responded. The results were analyzed according to type of practice (community, chain and hospital) and age (20--30 years, 31--40 years, 41--50 years, and 51 years and over). The results indicate that pharmacists are being asked about learning disabilities. Overall, 53% of the pharmacists responding had been asked about learning disabilities by parents, physicians, teachers or others. No significant interactions were found between the type of practice and age, and no significant main effect for type of practice was found in the ANOVA results for knowledge scores or attitude scores. Even though there were no differences owing to age in pharmacists' knowledge of learning disabilities, age was found to have a significant effect on attitudes toward increased pharmacist involvement in monitoring behaviors of learning-disabled children; the younger groups had a more positive attitude. The pharmacist seems to have the knowledge and attitudes required to become more actively involved in monitoring the medications and behaviors of children with learning disabilities.
