Can speech-evoked Auditory Brainstem Response become a useful tool in clinical practice?

Area of Science:

• Audiology
• Neuroscience
• Pediatrics

Background:

• Auditory processing disorders (APDs) affect how the brain interprets sounds.
• Accurate diagnosis of APDs is crucial for timely intervention and support.
• Speech-evoked Auditory Brainstem Response (ABR) offers an objective measure of auditory pathway function.

Purpose of the Study:

• To evaluate the clinical utility of speech-evoked ABR in identifying APDs.
• To determine the correlation between abnormal speech-evoked ABR and behavioral auditory processing assessments.

Main Methods:

• Retrospective analysis of 27 children and adolescents (aged 7-15) with abnormal speech-evoked ABR.
• Comparison of speech-evoked ABR results with behavioral auditory processing evaluation data.

Main Results:

• 85.15% of children with abnormal speech-evoked ABR also exhibited auditory processing disorders.
• Abnormal speech-evoked ABR results were highly predictive of deficits in behavioral auditory processing assessments.

Conclusions:

• Speech-evoked ABR serves as a valuable supplementary tool for diagnosing APDs in clinical settings.
• This objective measure is particularly useful for children under seven or those with challenging behavioral assessments.
• Abnormal speech-evoked ABR findings warrant further investigation for potential auditory processing deficits.
