Abstract
Le
traitement sensoriel modifié a été une caractéristique importante des
descriptions cliniques du "trouble du spectre de l'autisme"(TSA). Il
est prouvé que la dysrégulation sensorielle survient au début de la
progression de la TSA et affecte le fonctionnement social. Cet
article examine les preuves comportementales et neurobiologiques qui
décrivent comment les déficits sensoriels à travers de multiples
modalités (vision, audition, toucher, olfaction, gustation et
intégration multisensorielle) pourraient avoir une incidence sur les
fonctions sociales dans les TSA. On
discute des modèles théoriques de TSA et leurs implications pour la
relation entre le fonctionnement sensoriel et le fonctionnement social. En
outre, les différences nerveuses dans l'anatomie, la fonction et la
connectivité des différentes régions sous-jacentes au traitement
sensoriel et social sont également discutées. Nous
concluons qu'il existe de multiples mécanismes par lesquels la
dysrégulation sensorielle précoce dans les TSA pourrait se transformer
en déficits sociaux à travers le développement. Des recherches futures sont nécessaires pour clarifier ces mécanismes,
et une attention particulière devrait être accordée pour distinguer les
déficits du traitement sensoriel primaire et les processus cognitifs et
attentionnels altérés du haut vers le bas .
Altered sensory processing has been an important feature of the clinical descriptions of autism spectrum disorder (ASD). There is evidence that sensory dysregulation arises early in the progression of ASD and impacts social functioning. This paper reviews behavioral and neurobiological evidence that describes how sensory deficits across multiple modalities (vision, hearing, touch, olfaction, gustation, and multisensory integration) could impact social functions in ASD. Theoretical models of ASD and their implications for the relationship between sensory and social functioning are discussed. Furthermore, neural differences in anatomy, function, and connectivity of different regions underlying sensory and social processing are also discussed. We conclude that there are multiple mechanisms through which early sensory dysregulation in ASD could cascade into social deficits across development. Future research is needed to clarify these mechanisms, and specific focus should be given to distinguish between deficits in primary sensory processing and altered top-down attentional and cognitive processes.
