<title/> Purpose: The sensitivity, specificity, and efficiency of commonly used behavioral central auditory processing tests and test batteries were determined for 20 individuals with known lesions of the central auditory nervous system (CANS) and related auditory symptoms. Research Design: Twenty-nine individuals with no known neurological involvement served as the control group. Both groups were administered dichotic digits (DD), competing sentences (CS), frequency patterns (FP), and low-pass filtered speech (FS) tests. Data Analysis: Diagnostic indices for individual tests and test batteries comprised of two, three, or four tests were calculated both using a lax criterion in which failure on only one test in a battery led to a positive diagnosis and using a strict criterion in which failure on all tests in the battery was necessary to trigger a positive diagnosis. Results: The test battery providing the best balance between sensitivity and specificity varied as a function of criterion. The two-test DD-FP battery using a strict criterion demonstrated the best balance. Conclusions: Limitations of particular tests, the advantages of larger test batteries to more broadly examine multiple auditory processes, the degree to which the present results can be generalized clinically to populations without known brain lesions, and other clinical considerations are discussed.

<p class="abstract"><strong>Background:</strong> Amblyaudia is a weakness in the listener’s binaural processing of auditory information. Subjects with amblyaudia also demonstrate binaural integration deficits and may display similar patterns in their evoked responses in terms of latency and amplitude of these responses. The purpose of this study was to identify the presence of amblyaudia in a population of young children subjects and to measure mismatch negativity (MMN), P300 and cortical auditory evoked potentials (CAEPs) for those individuals.</p><p class="abstract"><strong>Methods:</strong> Subjects included in this study were divided into 2 groups control group that consisted of 20 normal hearing subjects with normal developmental milestones and normal speech development. The study group (GII) consisted of 50 subjects with central auditory processing disorders (CAPDs) diagnosed by central auditory screening tests. </p><p class="abstract"><strong>Results:</strong> With using dichotic tests including dichotic digits test (DDT) and competing sentence test (CST), we could classify these cases into normal, dichotic dysaudia, amblyaudia, and amblyaudia plus with percentages (40%, 14%, 38%, 8% respectively). Using event related potentials, we found that P300 and MMN are more specific in detecting neurocognitive dysfunction related to allocation of attentional resources and immediate memory in these cases.</p><p class="abstract"><strong>Conclusions:</strong> The presence of amblyaudia in cases of central auditory processing disorders (CAPDs) and event related potentials is an objective tool for diagnosis, prognosis and follow up after rehabilitation.</p>

Introduction The P3 cognitive evoked potential is recorded when a subject correctly identifies, evaluates and processes two different auditory stimuli. Objective to evaluate the latency and amplitude of the P3 evoked potential in 26 cochlear implant users with post-lingual deafness with good or poor speech recognition scores as compared with normal hearing subjects matched for age and educational level. Methods In this prospective cohort study, auditory cortical responses were recorded from 26 post-lingual deaf adult cochlear implant users (19 with good and 7 with poor speech recognition scores) and 26 control subjects. Results There was a significant difference in the P3 latency between cochlear implant users with poor speech recognition scores (G-) and their control group (CG) (p = 0.04), and between G- and cochlear implant users with good speech discrimination (G+) (p = 0.01). We found no significant difference in the P3 latency between the CG and G+. In this study, all G- patients had deafness due to meningitis, which suggests that higher auditory function was impaired too. Conclusion Post-lingual deaf adult cochlear implant users in the G- group had prolonged P3 latencies as compared with the CG and the cochlear implant users in the G+ group. The amplitudes were similar between patients and controls. All G- subjects were deaf due to meningitis. These findings suggest that meningitis may have deleterious effects not only on the peripheral auditory system but on the central auditory processing as well.

Background: According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosis of speech sound disorder (SSD) requires a determination that it is not the result of other congenital or acquired conditions, including hearing loss or neurological conditions that may present with similar symptomatology. Purpose: To examine peripheral and central auditory function for the purpose of determining whether a peripheral or central auditory disorder was an underlying factor or contributed to the child’s SSD. Research Design: Central auditory processing disorder clinic pediatric case reports. Study Sample: Three clinical cases are reviewed of children with diagnosed SSD who were referred for audiological evaluation by their speech–language pathologists as a result of slower than expected progress in therapy. Results: Audiological testing revealed auditory deficits involving peripheral auditory function or the central auditory nervous system. These cases demonstrate the importance of increasing awareness among professionals of the need to fully evaluate the auditory system to identify auditory deficits that could contribute to a patient’s speech sound (phonological) disorder. Conclusions: Audiological assessment in cases of suspected SSD should not be limited to pure-tone audiometry given its limitations in revealing the full range of peripheral and central auditory deficits, deficits which can compromise treatment of SSD.

This study investigated whether the P3 AERP could be used to reflect behavioral changes resulting from therapeutic intervention in a group of children with central auditory processing disorders (CAPDs). Results showed a significant decrease in P3 latency, along with a significant increase in P3 amplitude, following a structured treatment program. No changes occurred in either the CAPD control group or in the normal control group. These results suggest that the P3 AERP latency and amplitude measures are sensitive to changes in clinical status following a treatment program.

Background and Objectives: The relationship between hearing aid (HA) use and improvement in cognitive function is not fully known. This study aimed to determine whether HAs could recover temporal resolution or hearing in noise functions.Materials and Methods: We designed a prospective study with two groups: HA users and controls. Patients older than 45 years, with a pure tone average threshold of worse than 40 dB and a speech discrimination score better than 60% in both ears were eligible. Central auditory processing tests and hearing in noise tests (HINTs) were evaluated at the beginning of the study and 1, 3, 6, and 12 months after the use of a monaural HA in the HA group compared to the control group. The changes in the evaluation parameters were statistically analyzed using the linear mixed model.Results: A total of 26 participants (13 in the HA and 13 in the control group) were included in this study. The frequency (<i>p</i><0.01) and duration test (<i>p</i>=0.02) scores showed significant improvements in the HA group after 1 year, while the HINT scores showed no significant change.Conclusions: After using an HA for one year, patients performed better on temporal resolution tests. No improvement was documented with regard to hearing in noise.

Topicality: Long-term and pronounced psychoemotional tension leads to negative changes in the human body. Many aspects of cochleovestibular changes caused by psychoemotional stress are not studied enough to date. Aim: to increase the diagnostic efficiency of auditory and vestibular disorders in patients of active working age after exposure to stress. Materials and methods: 95 patients of active working age with dizziness, which manifested under stress, and 10 persons of control group were studied. The following tests were performed to all patients: survey with the questionnaire "Comprehensive stress assessment", pure tone and speech audiometry, measurement with filtered speech discrimination tests, assessment of the auditory adaptation level, impedancemetry, registration of auditory brainstem responses (ABR), computed static posturography, vestibular testing. Results and discussion: All subjects were divided into three groups according to the results of the survey with the questionnaire "Comprehensive stress assessment": Group 1 included 21 patients with moderate stress, Group 2 included 35 persons with severe stress that could not be compensated and Group 3 included 39 persons under severe stress, moreover 10 of them were on the verge of exhaustion of adaptive capacities. 60 (63.2 %) patients had normal hearing. 24 (25.2 %) subjects had statistically significant (P <0.05) hearing impairment in the high frequency zone compared with the control group, a statistically significant difference in hearing impairment was detected in the entire frequency range in 11 (11.6 %) persons. Central auditory processing disorders were detected in more than half of patients (according to various tests – from 29 (30.5 %) to 49 (51.6 %) persons). Central vestibular syndrome of varying severity was diagnosed in all 95 patients. The most pronounced disorders of balance according to posturography have been reported in patients with severe stress with vision deprivation in the position with closed eyes. Conclusions: An integrated approach allowed to identify and select, besides traditional research methods, supplementary diagnostic measures for optimal assessment of cochleovestibular changes in patients of active working age after exposure to stress, to detect cochleovestibular disorders and differential topical diagnostics of disorders of the central or peripheral portions of the auditory and vestibular analyzers. These included psychological testing, a test battery to determine central auditory processing disorders – hearing adaptation with load, filtered speech discrimination tests, registration of ABR, registration of postural balance using the Wii Balance Board platform, vestibular testing.

Abstract Background Migraine is a neurological disease associated with abnormal excitability in visual, somatosensory, and motor cortex. This study aimed to verify and compare auditory processing performance in migraine patients with and without dizziness and healthy controls. Results Sixty subjects were divided into 3 groups: control group, twenty normal healthy subjects, and study group I (twenty subjects diagnosed with migraine) and study group II (twenty subjects diagnosed with vestibular migraine). They were evaluated using the Central Auditory Processing Questionnaire for adults, tympanometry, pure tone audiometry, Psychophysical Central Auditory Tests, including Arabic Speech Intelligibility in Noise Test for adults, Arabic Dichotic Digit Test [version II], Gap in Noise Test, Duration Pattern Test, and Arabic Memory Tests. No significant difference was found between the two study groups I and II, but the significant difference was found between the study groups and the control group in all central auditory test results. Statistically significant difference was found between the control group and study groups I and II regarding all memory tests. The highest percentage of abnormality was present in temporal resolution and selective auditory attention in both study groups. There was no significant statistical correlation between the number of attacks/month and central auditory test results. There was no significant statistical correlation between the frequency of attacks in VM patients and central auditory test results. Conclusions Patients with migraine and vestibular migraine had an inferior performance in all psychophysical central auditory tests when compared with control. Also, there was no significant difference between the 2 study groups regarding central auditory test results which may support that both migraine with and without dizziness have the same pathophysiology.

Noisy Background

Mismatch negativity (MMN) has been widely used to study the function of central auditory processing in the elderly. However, current research has not yet considered the effect of noise and high-frequency hearing threshold on MMN in the elderly. The aim of this study was to evaluate the effect of aging and high-frequency hearing loss on speech-related MMN in noisy backgrounds. Additionally, the possible mechanisms of central auditory processing dysfunction in the elderly were investigated. Fifty people aged 61-80 (70 ± 5.8) years were recruited for this study. They were divided into a 61- to 70-year-old group and a 71- to 80-year-old group. Fifty younger adults aged 21-40 (31 ± 5.3) years were recruited as healthy controls. Pure-tone hearing thresholds were recorded. A speech discrimination score (SDS) and a speech-evoked MMN under white noise with a bandwidth from 125 to 8,000 Hz background condition were recorded. The relationships between SDS and MMN latency and amplitude were analyzed. The effects of age and binaural 2,000-, 4,000- and 8,000-Hz pure-tone hearing thresholds on MMN latency and amplitude were analyzed. We found that the hearing thresholds of 2,000, 4,000 and 8,000 Hz in the 61- to 70-year-old and 71- to 80-year-old groups were higher than those in the control group. The SDS in a noisy background in the 61- to 70-year-old and 71- to 80-year-old groups were lower than those in the control group. Speech-evoked MMN latency was longer in the 61- to 70-year-old and in the 71- to 80-year-old groups than in the control group (215.8 ± 14.2 ms). SDS and speech-evoked MMN latency were negatively correlated. Age and speech-evoked MMN latency were positively correlated, as were the binaural 4,000- to 8,000-Hz pure-tone hearing thresholds and speech-evoked MMN. This study suggests that in elderly subjects, the function of preattentive central auditory processing changes. Additionally, increasing age and high-frequency hearing thresholds create a synergy in neurons that is weakened in the MMN time window, which may be a cause of central auditory processing disorders in elderly subjects in noisy background conditions.

Background and Aim: Decoding deficit is the most common central auditory processing disorder (CAPD). Given the benefits of computer-based auditory training programs for treatment of central disorders and the lack of such programs in Persian language, this study aimed to develop a computer-based auditory training program for decoding skill. We also evaluated this program in 8 to12 year old children with CAPD.Methods: The first stage of research was to develop a computer-based auditory training program. This program consists of three levels of phonological discrimination, syllable discrimination, and word discrimination. The second stage was to determine the content and face validity of the program. The third stage was to assess the program effect on five children with decoding deficit. The research method was interventional and had a pretest and post-test design with another five children as control group. The staggered spondaic word, phonemic synthesis (PS) and speech in noise tests was used to assess the children performance before and after training.Results: Mean scores of staggered spondaic word (SSW) and PS tests of the experimental group were significantly difference before and after the auditory training (p<0.05) as compared to control group. However, there was no significant difference with regard to the speech-in-noise test results (p>0.05).Conclusion: This computer-based auditory training program can be considered as a preliminary tool for the rehabilitation and treatment of decoding deficits in children with CAPD.

Background: Including speech recognition in noise testing in audiological evaluations may reveal functional hearing deficits that may otherwise remain undetected. Purpose: The current study explored the potential utility of the Speech-in-Babble (SinB) test in the assessment of central auditory processing disorder (CAPD) in young children for whom diagnosis is challenging. Research Design: A cross-sectional analysis. Study Sample: Forty-one Greek children 4–13 yr of age diagnosed with CAPD and exhibiting listening and academic problems (clinical group) and 20 age-matched controls with no listening or academic problems participated in the study. Data Collection and Analysis: All participants’ auditory processing was assessed using the same tests and instrumentation in a sound-treated room. Two equivalent lists of the SinB test, developed at the Psychoacoustic Laboratory of the Aristotle University of Thessaloniki, were administered monaurally in a counterbalanced order. SinB consists of lists of 50 phonetically balanced disyllabic words presented in background multitalker babble. Five signal-to-noise ratios (SNRs) were used in a fixed order. The children were instructed to repeat the word after each presentation. The SNR at which the child achieved 50% correct word identification served as the dependent variable or outcome measure, with higher SinB scores (measured in SNR dB) corresponding to poorer performance. Results: SinB performance was better (lower SNR) for the normal control group versus the clinical group [F (1,35) = 43.03, p < 0.0001]. SinB inversely correlated with age for both CAPD and control groups (r = −0.648, p << 0.001 and r = −0.658, p < 0.005, respectively). Regression analysis revealed that linear models better explained the variance in the data than a quadratic model for both the control and CAPD groups. The slope (beta value of the linear model) was steeper for the clinical group compared to the control group (beta = −0.306 versus beta = −0.130, respectively). An analysis of covariance run with age as the covariate to assess the potential effect of comorbidity on SinB performance in children with CAPD with and without comorbid conditions revealed no significant difference<strike>s</strike> between groups [F (1,38) = 0.149, p > 0.05]. Conclusions: This study offers the first detailed presentation of the performance of Greek children on a Greek language SinB test. The main finding is that SinB scores improved as a function of age in a constant manner as represented by the slope of the linear regression line for both CAPD and control groups. Results suggest that this speech recognition in competition test holds promise for differentiating typically developing Greek children from those children with CAPD across the age range studied here (4–13 yr). The SinB seemed rather immune to the presence of comorbid conditions presented by some of the children in this study, suggesting its potential utility as a valid measure of central auditory processing. While there are many speech-in-noise or competition tests in English, there are fewer in other languages. Tests like the SinB should be developed in other languages to ensure that children demonstrating “listening” problems can be properly evaluated.
