Treatment of sensory information in neurodevelopmental disorders

Abstract

Introduction: The processing of information coming from the elementary sensory systems conditions the development and fulfilment of a child’s abilities. A dysfunction in the sensory stimuli processing may generate behavioural patterns that might affect a child’s learning capacities as well as his relational sphere. The DSM-5 recognizes the sensory abnormalities as part of the symptomatology of Autism Spectrum Disorders. However, similar features are observed in other neurodevelopmental disorders. Over the years, these conditions have been the subject of numerous controversies. Nowadays, they are all grouped together under the term of Neurodevelopmental Disorders in DSM-5. The semiology of these disorders is rich and complex due to the frequent presence of comorbidities and their impact on cognitive, behavioural, and sensorimotor organization but also on a child’s personality, as well as his family, his school, or his social relationships. Material and Methods: We carried out a review of the literature on the alterations in the treatment of sensory information in ASD but also on the different neurodevelopmental clinical panels in order to show their impact on child development. Findings. Atypical sensory profiles have been demonstrated in several neurodevelopmental clinical populations such as Autism Spectrum Disorder, Attention Deficit/Hyperactivity Disorders, Dysphasia and Intellectual Disability. Conclusion: Abnomalies in the processing of sensory information should be systematically evaluated in child developmental disorders.
