Insights

Children with neurofibromatosis type 1 (NF1) show early executive functions (EFs) impairment. Performance tests and parent/teacher ratings reveal significant deficits, highlighting the need for early assessment.

Area of Science:

  • Neuroscience
  • Pediatrics
  • Genetics

Background:

  • Executive functions (EFs) impairment is a known vulnerability in neurofibromatosis type 1 (NF1).
  • Limited data exists on EFs in preschool-aged children with NF1.

Purpose of the Study:

  • To assess executive functions in preschool children with NF1.
  • To compare EFs in NF1 children with a healthy control group.
  • To investigate the utility of performance-based tests and parent/teacher questionnaires.

Main Methods:

  • Evaluated 33 NF1 children (3-5 years) using 7 experimental EF tasks.
  • Administered BRIEF-P questionnaires to parents and teachers of NF1 children.
  • Compared NF1 children's performance to 52 age, gender, and socio-culturally matched healthy controls.

Main Results:

  • NF1 children scored significantly lower on 5 of 7 EF tasks compared to controls.
  • Parents and teachers reported significantly higher levels of EF concerns for NF1 children.
  • Weak correlations were observed between performance-based tests and questionnaire ratings.

Conclusions:

  • Results support early executive dysfunction in children with NF1.
  • Early and systematic assessment of EFs in NF1 is recommended.
  • Performance tests and questionnaires are complementary for investigating early EFs dysfunction in NF1.
