This brief, co-produced by the National Center on Deaf-Blindness (NCDB) and Accessible Teaching, Learning, and Assessment Systems (ATLAS), provides important information about students with dual sensory loss who also have significant cognitive disabilities, as well as recommendations for identification and implications for instruction. The…

Students with a hearing loss often have an additional disability. Although the number of deaf students with multiple disabilities is growing, research on this population has significantly decreased over the past quarter-century. The article reviews the literature on identification and placement of deaf students with multiple disabilities,…

At least 60% of children with disabilities have multiple disabilities including visual impairments (VI). Because the visual system is neurologically based, any problems of the neurological system will also likely affect vision. The estimated number of students with VI and additional disabilities has increased significantly over the years. Since…

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…

Describes current child-count systems that count students with visual impairments and additional disabilities in only one disability area. This results in an undercount of the incidence of visual impairment. Discusses the need for children to be initially counted by the disability of the lowest incidence. (CR)

The occurrence of dyskinetic movement disorder and its co-occurrence with stereotypic behavior among adults with mental retardation were studied in 98 adults with mental retardation. Results indicated that stereotypic movement disorder was associated with increased dyskinesia scores and that dyskinesia and stereotypy may be related by common…

This study compared interstate variability of prevalence rates for special education categories from 1984 to 1985 through 2001 to 2002, using the coefficient of variation (CV), which is designed to compare variances when the means of the groups compared are radically different. The category of learning disabilities, presumed by many to be the most…

Results were considered significant in that 11 percent of the students screened were identified as potentially hearing impaired as compared to 4 percent of the regular Baltimore City School student population who failed hearing screenings. (Author)

A study investigated the incidence of attention deficit hyperactivity disorder in 86 adults with severe mental retardation. Using the Diagnostic and Statistical Manual of Mental Disorders, 15% of the sample met the diagnostic criteria. This measure was not influenced by chronological age, adaptive age, IQ, or gender. (Author/CR)

A case study of a man with intellectual disability who died of polydipsia (excessive thirst and fluid consumption) is recounted. The article describes ways to identify polydipsia in individuals with intellectual disabilities, including detecting weight gain in the afternoon. Studies addressing polydipsia's coexistence with mental disorders are…

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…

This study surveyed the states concerning discrepancies between federal and state counts of the number of students identified as visually impaired. States overwhelmingly reported higher state counts than federal counts. Major reasons suggested for the discrepancy are federal count exclusion of students with additional disabilities and of students…

Noting a high incidence of learning disabilities among students with visual impairments, this article compares definitions of the two conditions. Common assessment approaches are discussed and those inappropriate for students with low vision or blindness are identified. Suggested intervention approaches include adaptation of the environment,…

This study examined the relationship between psychiatric and language disorders in 96 youth (mean age 13) in a private psychiatric hospital. Over 33% of subjects exhibited significant deficits in both phonology and syntax, qualifying for a language learning disability diagnosis, but only 44% of this group were receiving special education services…

Nurses applied standard behavioral criteria for major depression to evaluate 89 institutionalized adults with severe or profound intellectual disability. Results suggested that several additional behaviors listed on the Aberrant Behavior Checklist and the Developmental Behavior Checklist may be associated with this disorder in this population.…
