Sažetak
Introduction: NF1 is both clinically and genetically clearly defined as an autosomal dominant hereditary disease whose organic neurobiological processes have been examined for over a century. The relationship between NF1 and speech and language disorders has been relatively less well investigated.
Aim: To show the frequency of speech and language disorders in children with NF1.
Patients and methods: We selected a group of 112 children (54 girls and 58 boys) from our personal registry that covers 202 children with NF1. The selected children were longitudinally monitored by a speech pathologist. The age of children on initial examination varied between 1 year 9 months and 16 years 3 months. Semantic-syntactic structure and modalities of speech were analysed. Articulation was tested with the Vuletić test of articulation, while prosody and resonance were evaluated subjectively and then objectified with an acoustic analysis of the speech spectrum.
Results: 22% of patients had some degree of delayed early speech development. Speech disorders presented most often as disorders of resonance (81.2%) – hyperrhinophonia and rhinophonia mixta (79.5%) and hyporhinophonia (1.8%). Articulation disorders were diagnosed in 59.8% of patients and they were most often manifested as distortions (51.8%). Subjective evaluation of the voice found hoarseness in 50.9% of cases. Prosody was disrupted on the level of rhythm of speech with inter- and intraverbal blockades in 38.4% of children with NF1. Evaluation of reading and writing in 87 children with NF1 showed a high frequency of disorders – unspecific reading (19.5%) and writing (17.2%) errors.
Conclusion: The significant frequency of speech and language disorders in children with NF1 could have an important role in the appearance of learning disorders that are found in 50-60% of patients.
