[Autism spectrum disorders in neurofibromatosis type 1].

This case report describes a 12-year-old girl with neurofibromatosis type 1 (NF1), infantile autism, attention deficit hyperactivity disorder, executive difficulties and an IQ of 88. Her symptoms of autism being primarily of social communicative character seemed to be characteristic for patients with NF1 and autism spectrum disorders (ASD) compared to non-syndrome patients with ASD. Furthermore, her cognitive difficulties, including executive difficulties, attentional problems and an IQ-point reduction of ten, were very characteristic for NF1. There is a risk of overlapping symptoms, and the need for a thorough psychiatric examination is of great importance.
