Attention-deficit/hyperactivity disorder (ADHD) is characterized by high levels of inattention, hyperactivity, and impulsivity; however, these symptoms can result from a variety of reasons. To obtain a comprehensive understanding of the various difficulties of individuals with ADHD, especially when co-occurrence difficulties are present, it is…

Reading disability (RD) and math disability (MD) frequently co-occur, but the etiology of this comorbidity is not well understood. Groups with RD only (N = 241), MD only (N = 183), and RD + MD (N = 188) and a control group with neither disorder (N = 411) completed a battery of measures of internalizing and externalizing psychopathology, social and…

A vision evaluation and enhancement program was used with 59 elementary multihandicapped students to prevent future problems in educational and social development. Ss with eye-movement difficulties, eye-hand coordination problems and/or difficulty in visual perception skills improved after program participation. (CL)

This article criticizes the term "comorbidity" used to describe the overlap of developmental syndromes or disorders. Data from 179 school-age children are evaluated for criteria of seven disorders. Since fully 50 percent of the sample met the criteria for at least two diagnoses, the premise that these disorders are discrete categories on…

Evaluation of the relationship between hyperactivity and learning difficulties in 1,593 Australian elementary students indicated twice as many males as females with learning difficulties; 11% of the sample were hyperactive; 41% of the subjects with learning difficulties were also hyperactive; and 3.2% of all subjects had both hyperactivity and…

This article examines issues in the assessment of secondary and postsecondary students who are both learning disabled and hearing impaired. It notes origins of the gap between deaf education and the field of learning disabilities; considers who should evaluate these students; and discusses formal assessments, informal assessments, and use of…

This study examined consequences of the comorbidity of developmental coordination disorder (DCD) and learning disability (LD) for the severity and pattern of perceptual-motor dysfunction. Compared to children with only DCD, those with DCD and LD had poorer perceptual-motor ability, with particular difficulty performing manual dexterity and balance…

The prevalence of communication disorders in a population of 242 children with learning disabilities between 8 and 12 years of age was determined. A speech, language, or hearing problem was exhibited by 96.2 percent of the children. Only six percent of the children were considered to be receiving appropriate services. (Author/DB)

Evaluation of 357 students with either learning disability (LD), serious emotional disturbance (SED), or both (SED/LD), ages 6 to 18, found that children with LD differed from those with SED mainly in terms of severity of problem, not type of problem. Results suggest that students with both LD and SED are under-identified and underserved. (DB)

The study investigated the temporal stability and estimated the standard error of measurement for subtests of the Peabody Individual Achievement Test (PIAT) with 60 learning disabled and emotionally handicapped children (9 to 13 years old). (Author/SBH)

A study involving 494 twins with a reading disability (RD) and 373 typical twins found that individuals with RD were more likely to meet criteria for attention-deficit/hyperactivity disorder (ADHD) and that the association between RD and ADHD was stronger for symptoms of inattention than for hyperactivity symptoms. (Contains extensive references.)…

The study with 51 boys (ages 7 to 9 years) found that subjects classified as having both attention deficit disorder/hyperactivity and learning disabilities demonstrated the most external locus of control with subjects classified as only learning-disabled intermediate and subjects classified as only having attention deficit disorder/hyperactivity…

The use of standardized psychoeducational diagnostic instruments to identify learning disabilities was evaluated with 19 students (ages 7 to 13) with sensorineural hearing impairments. Students with hearing impairment were found to demonstrate learning disabilities with a frequency similar to that found in students with normal hearing, suggesting…

A study investigated electroencephalographic (EEG) differences between children with attention-deficit/hyperactivity disorder with reading disabilities (ADHD + RD) (n=20) or without (n=20), and 20 controls. Results indicate differences found in the ADHD + RD group represent an electrophysiological component associated with the reading disability…

This study investigated diagnosis of learning problems in 177 boys (ages 6-13) with behavior problems. The standard score discrepancy method and standard score plus low achievement method were more likely to identify children with above-average intelligence quotients as learning disabled, whereas a regression approach identified learning…
