Neuropsychological evaluation and parental assessment of behavioral and motor difficulties in children with neurofibromatosis type 1.
Kids with NF1 show a clear pattern of visuospatial, fine-motor, and learning problems that you can spot with quick tests and parent questions.
01Research in Context
What this study did
Vassos et al. (2016) looked at kids with neurofibromatosis type 1.
They gave each child a short battery of brain games.
Parents also filled out forms about daily behavior and motor skills.
What they found
Most kids with NF1 struggled with visuospatial tasks and fine-motor jobs.
Learning and attention problems showed up again and again.
When NF1 ran in the family, the cognitive hit was larger than in sporadic cases.
How this fits with other research
Baker et al. (2005) did the same kind of parent-plus-testing map in juvenile neuronal ceroid lipofuscinosis. Both teams prove you can sketch a full behavioral picture even in rare disorders.
Wagner et al. (2011) surveyed seven genetic syndromes and found unique ASD-risk profiles for each. V et al. narrow the lens to one syndrome but still find a distinct NF1 fingerprint, so the two studies complement, not clash.
Azim et al. (2025) argue we should drop single-diagnosis checklists and score cross-cutting domains instead. V et al. already did this for NF1 by testing visuospatial, motor, learning, and behavior together, giving a live example of the transdiagnostic approach.
Why it matters
If a client has NF1, expect trouble with puzzles, handwriting, and staying on task. Use brief tabletop visuospatial tests and ask parents about daily motor slips. Track the data across domains rather than labeling \"ADHD\" or \"LD\" first. When NF1 is familial, plan for more intense academic support from the start.

03Original abstract
Neurofibromatosis type 1 (NF1) is an autosomal dominant multisystem disorder, with large inter and intrafamilial clinical variability and uncertain prognosis. In children with NF1 cognitive disorders, learning difficulties and behavioral problems are common. The present study aims to establish the neuropsychological and behavioral profiles of 78 patients with NF1, aged between 5 and 18 years, and to examine the relationship between these profiles and the transmission of NF1 (sporadic vs. familial), clinical manifestations, and environmental factors. We used several questionnaires completed by parents and neuropsychological tests. The results confirmed specific neuropsychological disabilities in children with NF1, especially involving visuospatial and fine motor skills, learning difficulties and behavioral problems. Cognitive difficulties were significantly more frequent in patients with familial than in those with sporadic NF1. All parental questionnaires were correlated with each other, but parental reports were not associated with FSIQ, SES, school status, and clinical manifestations of the disease. Neuropsychological tests were poorly related to parental reports of cognitive and behavioral difficulties.
