The Effect of Tinnitus on ABR Latencies
Ear and Hearing, 1990
Comparisons were made of the ABR latencies of tinnitus (T) and nontinnitus (NT) patient groups balanced for age and gender and matched for acoustic reflex threshold (ART)s, 1000 to 4000 Hz and 4000 Hz auditory thresholds, and normal hearing. In the ART match, prolongations of wave I [r(94) = 4.42, p < O.OOl], wave 111 [f(94) = 2.72, p < 0.011, and wave V [t(94) = 3.32, p < 0.011 and the Ill-V interval [t(94) = 2.48, p < 0.02) were seen in T subjects. Wave I in 1 to 4 kHz matched [2(62) = 3.13, p < 0.0051 and normal-hearing subjects [r(30) = 2.58, p < 0.01] was prolonged in T females. The utility of using wave I as a diagnostic indicator for tinnitus in females is discussed. Auditory evoked potentials (AEPs) are used to examine the synchronous discharge of fibers in the auditory pathway and identify the presence of abnormal neuronal activity. The waveforms that occur in the first 10 msec of an AEP are termed the ABR (
Correction: Selective Impairment in Frequency Discrimination in a Mouse Model of Tinnitus
PLOS ONE, 2015
Tinnitus is an auditory disorder, which affects millions of Americans, including active duty service members and veterans. It is manifested by a phantom sound that is commonly restricted to a specific frequency range. Because tinnitus is associated with hearing deficits, understanding how tinnitus affects hearing perception is important for guiding therapies to improve the quality of life in this vast group of patients. In a rodent model of tinnitus, prolonged exposure to a tone leads to a selective decrease in gap detection in specific frequency bands. However, whether and how hearing acuity is affected for sounds within and outside those frequency bands is not well understood. We induced tinnitus in mice by prolonged exposure to a loud mid-range tone, and behaviorally assayed whether mice exhibited a change in frequency discrimination acuity for tones embedded within the midfrequency range and high-frequency range at 1, 4, and 8 weeks post-exposure. A subset of tone-exposed mice exhibited tinnitus-like symptoms, as demonstrated by selective deficits in gap detection, which were restricted to the high frequency range. These mice exhibited impaired frequency discrimination both for tones in the mid-frequency range and high-frequency range. The remaining tone exposed mice, which did not demonstrate behavioral evidence of tinnitus, showed temporary deficits in frequency discrimination for tones in the mid-frequency range, while control mice remained unimpaired. Our findings reveal that the high frequency-specific deficits in gap detection, indicative of tinnitus, are associated with impairments in frequency discrimination at the frequency of the presumed tinnitus.

Recently, while I was searching articles related to intrathecal nalbuphine, I found one article [1] interesting. But, unfortunately there are some errors in that article which I would like to bring to your kind attention.
Objective: To study the variability of auditory brainstem response (ABR) and middle latency response (MLR) over a long term period. Methods: 50 normal hearing subjects participated in the study. All the subjects were tested at 3 months, 6 months and 12 months of the initial testing. The absolute latencies and interpeak latencies of ABR waves and amplitudes & latencies of waves Na and Pa of MLR were measured. Results: The Repeated measure ANOVA did not reveal any statistically significant difference (p>0.05) between interpeak latencies of wave I-III, III-V and I-V across the four visits. The amplitude of MLR wave Pa showed no significant difference across four visits. However significant difference (p<0.05) across visits was observed for latency of wave Na. Conclusions: The absolute latencies of wave III & V and the interpeak latencies of waves I-III, III-V and I-V have good test retest reliability. Reliability of wave I however has not been established. Amplitude of wave Pa has good test retest reliability. Significance: The ABR and MLR can be used as monitoring tools in a number of cases like neurodegenerative disorders, progressive disorders of the central nervous system.
Gap in Noise Auditory Brainstem Responses: A Systematic Review
Function and Disability Journal, 2023
Background and Objectives: The gap in noise auditory brainstem responses (GIN-ABR) is a valuable assessment tool for auditory temporal processing, offering non-invasive and objective measurements encompassing the entire auditory system from the cochlea to the brainstem. This method has been utilized in investigating various factors, including age-related effects, hearing loss, and tinnitus. This systematic review was conducted to present a thorough examination of (GIN-ABR), encompassing its methodology, applications, and inherent limitations. Methods: This study was conducted based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Cochrane, PubMed, and Ovid databases were used to extract English articles from 1990 to June 2023. The search terms used were "gap in noise auditory brainstem response", "ABR gap detection", "ABR gap duration", "ABR gap threshold", and "ABR temporal processing". Articles were included if gap-evoked ABR was used, investigating the effect of any factor on the responses, and using any gapped stimulus type. Articles whose evoked potentials did not include ABR waves were excluded. The outcome of interest was gap-evoked ABR in different participant groups. Results: A total of 10 studies were deemed suitable for inclusion in the review. The articles were reviewed that including the study population, the methods, and the results. Despite the variability in the results of the studies, in the aged group, longer latency shifts and decreased peak amplitude were reported compared to the young group. Correspondence of behavioral thresholds with GIN-ABR has also been mentioned in studies. Conclusion: The GIN-ABR method has been extensively utilized in investigating various factors, including age-related effects, hearing loss, and tinnitus. Notably, GIN-ABR has several clinical advantages, such as cost-effectiveness, shorter test duration, independence from alertness levels, attention, sleep depth fluctuations, or medication. Additionally, it has shown its compatibility with psychophysical tests. Further research is warranted to explore the impact of various factors on different components of GIN-ABR. Consequently, with its promising findings and growing body of research, the gap in noise test has the potential to be gradually integrated into the set of audiological clinical evaluations.

Objectives: Overall success of current tinnitus therapies is low, which may be due to the heterogeneity of tinnitus patients. Therefore, subclassification of tinnitus patients is expected to improve therapeutic allocation, which, in turn, is hoped to improve therapeutic success for the individual patient. The present study aims to define factors that differentially influence subjectively perceived tinnitus loudness and tinnitus-related distress. Methods: In a questionnaire-based cross-sectional survey, the data of 4705 individuals with tinnitus were analyzed. The selfreport questionnaire contained items about subjective tinnitus loudness, type of onset, awareness and localization of the tinnitus, hearing impairment, chronic comorbidities, sleep quality, and psychometrically validated questionnaires addressing tinnitus-related distress, depressivity, anxiety, and somatic symptom severity. In a binary step-wise logistic regression model, we tested the predictive power of these variables on subjective tinnitus loudness and tinnitus-related distress. Results: The present data contribute to the distinction between subjective tinnitus loudness and tinnitus-related distress. Whereas subjective loudness was associated with permanent awareness and binaural localization of the tinnitus, tinnitusrelated distress was associated with depressivity, anxiety, and somatic symptom severity. Conclusions: Subjective tinnitus loudness and the potential presence of severe depressivity, anxiety, and somatic symptom severity should be assessed separately from tinnitus-related distress. If loud tinnitus is the major complaint together with mild or moderate tinnitus-related distress, therapies should focus on auditory perception. If levels of depressivity, anxiety or somatic symptom severity are severe, therapies and further diagnosis should focus on these symptoms at first.

The aim of this study is to investigate auditory brainstem response (ABR) in patients with benign paroxysmal positional vertigo (BPPV) accompanied by tinnitus and to suggest possible interpretative hypotheses. Methods Ninety individuals were included in the study. Individuals were separated into three groups: patients reporting tinnitus with BPPV (Group I), patients with BPPV (Group II), and a control group. The ABR test was applied at a low and at a high rate. Results For patients reporting tinnitus with BPPV, tinnitus was found to be localized in the ear affected by BPPV. Tinnitus disappeared after therapeutic interventions in 23 individuals with tinnitus. The difference between the V. wave = false Wave V = true latency at high rate and V. wave = false Wave V = true latency at a low rate in the affected ears of all individuals with BPPV (Groups I and II) was significantly long. In the affected ears of all BPPV patients, at a high rate of ABR, the absolute latency of the Wave III was found to be significantly longer than for the control group. Conclusions Individuals with BPPV showed prolonged latencies in affected ears in a high rate of ABR without the effect of tinnitus. High rate of ABR in individuals with BPPV can be used to obtain preliminary information in cases where ischemia in the auditory pathways is suspected in BPPV formation.
