Not Applicable

Completed

• Conditions: Neurofibromatosis Type 1

• Registration Number: NCT02397967
• Lead Sponsor: University Hospital, Toulouse

Brief Summary

A national, multicenter, randomized, transverse clinical trial, estimating the existence of phonological deficits in children with NF1 children compared with control children without NF1 with the same reading level.

Detailed Description

To determine the phonological and visio -spatial performances at the NF1 children.

Primary Outcome Measures

Name	Time	Method
Phonological deficits evaluated by the metaphonological capabilities including a subtraction test and phonemic Acronym test and memory capacity with phonological phonological memory test.	24 hours	Evaluate whether there is a specificity of phonological deficits in children with NF1 compared with a population of children with the same age and same reading level, taking into account the intellectual level.

Secondary Outcome Measures

Name	Time	Method
Visual-perceptual performance established from three tests: Test of Identical Forms (Thurstone), Judgment Test of orientation Lines (Benton) and global and partial deferral Tasks (S Valdois).	24 hours	Studying the correlations between phonological deficits and visio-spatial and literacy skills.
