Behavioural, academic and neuropsychological profile of normally gifted Neurofibromatosis type 1 children.
In the present study the neuropsychological, academic and social-emotional profiles were examined in Neurofibromatosis type 1 (NF1) children. ⋯ Nearly 50% (8/17) of the children showed learning disabilities, when corrected for IQ in the academic evaluations. Isolated impaired literacy skills, particularly spelling problems, were most frequent (4/8), whereas a pure arithmetic learning disability was rare (1/8). Three children presented both learning disabilities. Results on academic and neuropsychological tests did not fit the well-known types of learning disabilities -- nonverbal learning disability (NLD) and dyslexia. Nearly all NF1 children showed visual perceptual and executive dysfunctions. In this study, teachers more frequently reported behavioural problems in NF1 children than parents, as opposed to literature data in a general population. The correspondence of the perception of internalizing problems between the children and teachers was greater than between children and their parents. No correlation was found between the performances on the WISC-R, specific neuropsychological results, academic performances and behavioural problems. The Deficiency in Attention, Motor and Perception (DAMP) concept seems most appropriate in order to describe the neuropsychological deficits and their repercussions on behavioural and academic performances seen in NF1 children.
