Description: Central auditory processing disorders (CAPD) present diagnostic challenges due to the involvement of complex neural networks responsible for sound localization, auditory discrimination, and temporal processing. This session explores the application of electrophysiological methods—particularly auditory brainstem responses (ABR), middle latency responses (MLR), and cortical auditory evoked potentials (CAEP)—as objective tools to assess central auditory function. Emphasis will be placed on clinical applicability, interpretation strategies, and integration with behavioural test findings.
Outcome Objectives: At the end of this session, participants will be able to:
Define the neural mechanisms underlying central auditory processing.
Describe key electrophysiological techniques relevant to CAPD assessment.
Identify electrophysiological patterns associated with central auditory dysfunction.
Integrate objective and behavioural findings for a comprehensive clinical evaluation.
Background: Central auditory processing involves the perceptual processing of auditory information within the central nervous system and the neurobiological activity that underpins this processing. CAPD can affect language development, learning, and everyday communication, particularly in pediatric and geriatric populations. Behavioural tests, while informative, are limited by their reliance on attention, memory, and language skills.
Electrophysiological methods provide a means of assessing auditory system integrity and processing efficiency independent of patient cooperation. Studies have demonstrated the value of CAEPs and MLRs in identifying cortical involvement and temporal abnormalities in CAPD cases. Moreover, the frequency-following response (FFR) has been proposed as a promising tool to evaluate the encoding of complex sounds at the subcortical level.
These objective measures complement behavioural evaluations and can support differential diagnosis, especially in populations with limited behavioural test reliability. As audiology increasingly incorporates neurophysiological tools into routine practice, electrophysiology-based assessments are becoming vital for evidence-based management of CAPD.
This proposal aims to highlight the growing clinical relevance of electrophysiological methods in the assessment of central auditory processing. By presenting objective techniques such as ABR, MLR, and CAEP within a structured clinical framework, the session seeks to enhance diagnostic accuracy, especially in complex or behaviourally inconclusive cases. It will contribute to bridging the gap between auditory neuroscience and daily audiological practice through evidence-based insights.
I have been working as a Research Assistant at Istanbul Medipol University for approximately 1.5 years. I completed my undergraduate and master's degrees at Medipol University, and I am currently pursuing my PhD (thesis phase) at Istanbul University-Cerrahpaşa. My research primarily focuses on Central Auditory Processing, Electrophysiology, and Hidden Hearing Loss. I have published national and international papers and presented at conferences on these topics, particularly in the areas of central auditory processing and electrophysiology. I am eager to give a presentation on the topic I mentioned if the scientific committee deems it appropriate. I would like to express my gratitude to my professors for contributing to the organization of such a prestigious conference as IFOS in Istanbul.

I am a lecturer in the Department of Audiology at Istanbul Medipol University, where I have worked since 2017. I completed my MSc in Audiology in 2021 and am currently pursuing a PhD in the same field. My doctoral thesis aims to improve listening performance in hearing aid users by enhancing cognitive abilities. My master’s thesis investigated auditory working memory and listening effort in musicians, and I co-authored a study on speech-in-noise performance in cochlear implant users. I am also involved in a TÜBİTAK-funded project on hearing and ADHD screening in school-age children.
