The click-evoked auditory brainstem response (ABR) is widely used in clinical settings, partly due to its predictability and high test-retest consistency. More recently, the speech-evoked ABR has been used to evaluate subcortical processing of complex signals, allowing for the objective assessment of biological processes underlying auditory function and auditory processing deficits not revealed...

Auditory processing deficits have been hypothesized as an underlying mechanism for stuttering. Previous studies have demonstrated abnormal responses in subjects with persistent developmental stuttering (PDS) at the higher level of the central auditory system using speech stimuli. Recently, the potential usefulness of speech evoked auditory brainstem responses in central auditory processing diso...

the clinical and phenotypic features of two siblings (a 12 years old girl and her 7 year old brother) with cockayne syndrome are described. the main problems were mild to moderate mental retardation, dwarfism, clumsy gait, photosensitive skin lesions and progeroid (senile like) appearance. brain ct - scans revealed symmetrical, well defined areas of calcification mainly located at lenticular nu...

BACKGROUND Auditory-evoked potentials have proven useful in the objective evaluation of sound encoding at different stages of the auditory pathway (brainstem and cortex). Yet, their utility for use in clinical assessment and empirical research relies critically on the precision and test-retest repeatability of the measure. PURPOSE To determine how subcortical/cortical classes of auditory neur...

Background: the suppression effect with contralateral white noise observed in the brainstem auditory evoked potential can be influenced by the efferent auditory system. Aim: to evaluate the suppression effect with contralateral white noise in the Brainstem Auditory Evoked Potential of individuals with normal hearing. Methods: 25 individuals, ranging in age from 18 to 30 years, of both genders, ...

introduction: one of the most common pathologies in neonates is hyperbilirubinemia, which is a good marker for damage to the central nervous system. the sensitivity of the auditory system to bilirubin has been previously documented, with much discrepancy in its effects on auditory brainstem response results. thus the objective of this study was to evaluate the effects of hyperbilirubinemia on a...

Herein, we report a case of multiple sclerosis in which peripheral and central hearing, were evaluated through early (brainstem), middle and late auditory evoked potentials before and after corticosteroid therapy. Auditory evaluation revealed better performance on all post-treatment tests. In this case, central auditory function tests (behavioral and electrophysiological) identified the locatio...

background and aims: this is a pilot study investigated the prevalence of hearing impairment and the impact of the known risk factors for hearing loss on infants at risk born in kuwait. methods: two hundred infants with risk of hearing impairment who met the joint committee on infants hearing (1990) criteria were screened. all newborns were included in this study if they had hospital stay for m...

BACKGROUND To characterize the findings of brainstem auditory evoked potential in HIV-positive individuals exposed and not exposed to antiretroviral treatment. MATERIAL AND METHODS This research was a cross-sectional, observational, and descriptive study. Forty-five HIV-positive individuals (18 not exposed and 27 exposed to the antiretroviral treatment - research groups I and II, respectively...
