Auditory neuropathy is a disorder where the transmission of auditory signals from inner ear to the auditory nerve and auditory brainstem is distorted. Auditory neuropathy is not a homogenous disorder, rather, a collection of auditory abnormalities with distinctly different sites of dysfunction, diverse etiologies and causes, variations in patterns of auditory findings, and in most cases, corres...

Background: Although it is not a new disorder, in recent times we have attained a greater understanding of auditory neuropathy (AN). In this type of hearing impairment, cochlear hair cells function but AN victims suffer from disordered neural transmission in the auditory pathway. The auditory neuropathy result profile often occurs as a part of that of the generalized neuropathic disorders, indi...
Background: The main result of hearing impairment is reduction of speech perception. Patient with auditory neuropathy can hear but they can not understand. Their difficulties have been traced to timing related deficits, revealing the importance of the neural encoding of timing cues for understanding speech. Objective: In the present study psychoacoustic perception (minimal noticeable differen...
results: the average of dyssynchrony in eight cycles showed a positive correlation with dyssynchrony in target beat rr1/rr2 = 1. average of dyssynchrony in target beat was 46.77 msec, and average of 8 cycle was = 47.701, (p value = 0.776, pearson linear correlation 0.769). objectives: we proposed to evaluate intraventricular mechanical dyssynchrony by measuring time-to-peak systolic velocity be...
REVIEW Auditory neuropathy is a disorder characterised by preservation of outer hair cell function, with normal otoacoustic emissions and/or cochlear microphonics, but an absent or distorted auditory brainstem response. PURPOSE This study aimed to objectively assess hearing thresholds in patients with auditory neuropathy, using the auditory steady state response. MATERIALS AND METHODS Thirt...
hyperbilirubinemia at neonatal period is one of the major deteriorating factors of the auditory system. if left untreated, it may cause certain cerebral damage. this study aims to evaluate the impact of hyperbilirubinemia on the hearing of neonate. this study was conducted on 35 newborn babies with jaundice (bilirubin more than 20 mg/dl). auditory brainstem response (abr) and transient evoked o...
Auditory neuropathy is defined as a sensorineural hearing loss characterized by normal cochlear hair cell function and absent or abnormal auditory brainstem evoked potentials. These people can hear the sound but can not understand it. They have neural hearing loss and the auditory rehabilitation approach for these people may be different from those who have sensorineural hearing loss. Therefore...
Newborn hearing screening test is very important in the early diagnosis of childhood hearing loss because it affects language development. Auditory neuropathy is a spectrum disorder characterized by abnormal auditory brainstem response but preserved otoacoustic emission and cochlear microphonics. In general, auditory neuropathy patients have poor word discrimination and variable patterns of pur...
