Abstract:	The cognitive function of adults with von Recklinghausen's neurofibromatosis (NF-1) was examined. This study sought to replicate in an adult sample the findings of decreased visuospatial and attention abilities reported for many children with NF-1. Specifically, it was anticipated that adults with NF-1 would be classified separately from unaffected controls according to visual and attention–executive function skills. Second, this study examined whether language skills discriminated between adults with NF-1 and unaffected controls. The sample included 20 participants with NF-1 and 25 control participants. All participants were administered a battery of neuropsychological tests (Developmental Test of Visual-Motor Integration (VMI), Judgment of Line Orientation (JLO), Visual Form Discrimination, Booklet Category Test, Figure Cancellation, Peabody Picture Vocabulary Test–Revised (PPVT–R), Sentence Repetition, Controlled Oral Word Association). The results of a discriminant function analysis partially supported the hypothesis: Two of the tests of visual-spatial skill (VMI, JLO) and one of the language tests (PPVT–R) were found to be the best predictors for group membership. The discriminant function accounted for 45% of the variance between the groups and correctly classified 15 of the NF-1 participants and 21 of the control participants. Post hoc exploratory analyses revealed that the VMI was the most important test in discriminating between the groups. It is suggested that patients with NF-1 will tend to have sparing of basic cognitive functions but will have greater impairment on tests that use multiple cognitive skills. [ABSTRACT FROM AUTHOR]
