Peripheral and central auditory findings in children with Language Disorders

Introduction: Language disorders correspond to persistent changes in the acquisition and use of language, without a basic etiology to justify such changes. Knowing the close relationship between hearing and language development, exams and audiological symptoms can be used in an attempt to assist in the early identification and therapeutic process of children with the disorder, however, research conducted with subjects with impairments in oral language are still scarce. Objective: To investigate the influence of Language Disorders on the results of the cortical auditory evoked potential (CAEP), the acoustic reflex and the occurrence of hyperacusis. Methods: Dissertation structured in two manuscripts: (1) integrative literature review, without limitation of language or year of publication, carried out in five electronic databases and in the gray literature, in order to answer what are the characteristics of the CAEP, with speech stimulus in children with Language Disorders; (2) cross-sectional study, conducted with children with a diagnostic hypothesis of Language Development Disorder, Phonological Disorder or with typical development. Participants underwent complete audiological assessment and parents will be asked to answer the auditory hypersensitivity questionnaire. The data were analyzed using descriptive statistics and it is intended to insert the inferential one. Expected results: Higher latencies and lower amplitudes in cortical potential, changes in the acoustic reflex, as well as a higher occurrence of hyperacusis in children with Language Disorders.
