Résumé
Among the many lines of research related to autism, investigations of sensory dysfunction have recently gained attention. The objective of this article is to briefly review the main findings of sensory deficits in autism, raise possibilities of early identification research in the area, and discuss the significance of these sensory problems for the understanding of autism. A review of the scientific literature with regard to sensory problems in autism was performed. A review of autobiographical reports of high-functioning autistic individuals was also performed. This review showed that sensory problems have always been mentioned in the autism literature, but their relevance has been underestimated. Scientific research and autobiographical reports suggest a high prevalence of sensory problems in autism. Although not yet considered in the official diagnosis of autism, sensory problems appear to not only exert a considerable impact on the configuration of the disorder but also directly influence autistic persons in their daily lives. Such impairments may begin to be thought of as fundamental in autism. However, these characteristics deserve to be further investigated by researchers who are dedicated to the study of autism.
