Language as a vehicle for human development has an important impact on social processes which are decisive in the establishment of optimal living conditions. Modern studies have found that skills that make of language an activity of complex multisensory integration are determined by the oscillation rhythms of the different brain waves described from neurosciences. In the literature has described an abnormal pattern of oscillations, responsible for communicative deficiencies in individuals with Autist Spectrum Disorders and beside with social deficits, resulting in a typically characteristic profile. Brain waves show an impact on the mental states that be high cognitive demand as learning, communication and speech understanding, widespread difficulties in this population. The recent findings presented here and product of a judicious bibliographic review, are characterized within speech therapy making it possible to land the intervention processes to the linguistic and cognitive needs of these individuals, using biological mechanisms and resulting in possible procedures of greater relevance and effectiveness, that improve user’s life quality and motivate speech therapy and similar professionals to expand their knowledge in this interesting field.
