Frequency of central auditory processing disorder in attention deficit hyperactivity disorder and specific learning disorder

Abstract

Objectives: This study aims to investigate the prevalence of individuals with central auditory processing disorder (CAPD) amongchildren with neurodevelopmental disorder, to establish whether there is an objective screening test parameter that identifiesindividuals with neurodevelopmental disorder without CAPD, and to scan the history of these individuals for a unique feature.Patients and Methods: The study included 94 patients (69 males, 25 females; mean age 8.5±1.2 years; range, 7 to 13 years) withspecific learning disorder (SLD) and/or attention deficit hyperactivity disorder (ADHD). After assessment by child and adolescentpsychiatry, the Staggered Spondaic Word (SSW) test was performed in addition to a full audiologic evaluation.Results: Twenty-four patients (27.2%) with SLD and/or ADHD had CAPD according to SSW criteria. Twenty-eight patients had SLD,27 had ADHD, and 39 had mixed-type neurodevelopmental disorder. Central auditory processing disorder rate was significantlyhigher in the mixed group than in the ADHD group (p
