title: Cognitive function and academic performance in children with neurofibromatosis type 1.
abstract: The authors evaluated 51 consecutive children with NF1 (aged eight to 16 years) to determine the frequency of intelectual impairment and learning disability due to NF1 alone, the profile of learning disabilities and the effect of clinical variables. 40 children completed the full assessment protocol. There was no support for a profile of predominantly visuoperceptual deficits in the NF1 population. There was no discrepancy between verbal and performance IQ, and the deficits in function were wide ranging. Clinical variables such as age, sex, socio-economic status, disease severity, macrocephaly and family history of NF1 were not associated with cognitive deficits. These results emphasise the need for developmental evaluation to be included in the routine assessment of children with NF1.
