Neurofibromatosis
|January 1, 1988
Summary
Children with von Recklinghausen's neurofibromatosis (VRNF) exhibit distinct learning and visual-perceptual differences compared to other learning-disordered (LD) students. These findings suggest VRNF learning issues may represent a unique category of learning disabilities.
Area of Science:
- Neuroscience
- Developmental Psychology
- Genetics
Background:
- Von Recklinghausen's neurofibromatosis (VRNF) is a genetic disorder.
- Children with VRNF often experience school learning problems.
- The specific nature of these learning problems in VRNF is not well-defined.
Purpose of the Study:
- To compare the learning profiles of children with VRNF to those with general learning disabilities (LD).
- To identify specific cognitive and academic differences associated with VRNF.
- To determine if VRNF-related learning issues constitute a distinct category of learning disabilities.
Main Methods:
- Compared 32 children with VRNF and learning problems to a matched sample of LD students.
- Utilized WISC-R, Kaufman Assessment Battery for Children (Kaufman's perceptual organization factor), and visual-perceptual tests.
- Assessed reading achievement and Continuous Performance Test (CPT) error patterns.
Main Results:
- VRNF children showed significant differences in WISC-R IQ discrepancies and Kaufman's perceptual organization.
- Visual-perceptual functioning measures were strong predictors of group membership (96% LD, 63% VRNF).
- VRNF subjects differed in reading achievement and CPT error patterns compared to LD students.
Conclusions:
- Learning problems in VRNF may represent a distinct form of learning disability.
- Visual-perceptual deficits are a key characteristic differentiating VRNF learning issues.
- Further research is needed to characterize VRNF-associated learning disabilities.
