Audiological profile in children with autism spectrum disorders

ABSTRACT

Background: Autism spectrum disorder is defined by the Diagnostic Statistical Manual of Mental Disorders V [DSM V] as a neurobehavioral disorder manifested by persistent deficits in social and communication interaction, deficits in developing, understanding and maintaining relationships, as well as abnormal and fixed interests and repetitive behavior. Symptoms must be present at early childhood and interfere with daily function. The majority of individuals with ASD demonstrate some degree of auditory dysfunction. The level and expression of this dysfunction ranges from deafness and increased thresholds to hyperacusis and difficulty listening with background noise
