Exploring the Correlations Between Language Impairments, Central Auditory Processing Disorder, Neuropsychiatric Functions, and Seizure Timing in Children With Self-Limited Epilepsy With Centrotemporal Spikes.

Children with self-limited epilepsy with centrotemporal spikes often face language impairments and central auditory processing difficulties. The correlations between these issues, seizure timing, and neuropsychiatric challenges are not fully understood. This study delves into the connections between language impairments and central auditory processing difficulties in cases with self-limited epilepsy with centrotemporal spikes, examining their links with seizure occurrence and neuropsychiatric function. Patients with self-limited epilepsy with centrotemporal spikes were categorized based on seizure timing: group 1 experienced seizures postbedtime, and group 2 prewaking. Both, alongside controls, underwent the Turkish Expressive and Receptive Language Test (TIFALDI) for language skills, and the Frequency Pattern and Duration Pattern tests for central auditory processing difficulties. Neuropsychiatric assessments involved the Wechsler Intelligence Scale for Children-Revised, the Strengths and Difficulties Questionnaire, the Conners Parent Rating Scale-Revised Short, and the Barratt Impulsiveness Scale-11. The study comprised 56 patients with self-limited epilepsy with centrotemporal spikes (ages 6-13) and 32 healthy controls. Both groups significantly lagged behind controls on the Frequency Pattern and Duration Pattern tests (P < .001). In the TIFALDI, the expressive language scores varied between group 1 and controls (P = .04) but not the receptive language scores or the test's expressive and receptive language results between group 2 and controls (P > .05). In the Strengths and Difficulties Questionnaire, group 1 diverged from controls in behavioral and kind and helpful behavior scores (P = .016 and P = .012). Group 1's Barratt Impulsiveness Scale-11 values surpassed controls' (P = .038). Children with self-limited epilepsy with centrotemporal spikes have a high central auditory processing difficulties prevalence, regardless of seizure timing. Those with postsleep seizures tend to confront expressive language difficulties, alongside issues in prosocial behavior and impulsivity.

Central auditory processing and cognitive abilities after mild traumatic brain injury in school-aged children

Objective The current study aimed to explore (1) school-aged children’s auditory and cognitive abilities and (2) their perceptions (self-reported and parents) of listening behaviours and symptoms following mild traumatic brain injury (mTBI). Design Prospective cohort study. Study Sample Twenty-one children aged 8 to 12 participated in this study. Eleven children with mTBI were diagnosed in the emergency department, and 10 were matched controls. They were assessed twice, in the acute (≤14 days) and chronic (≥3 months) stages post-injury, using six central auditory behavioural tests, a cognitive screening battery, and questionnaires. ANOVA and correlation analysis were performed. Results Group differences were present in three auditory tests as children with mTBI obtained poorer scores than controls (Pitch Pattern Sequence Tests - PPST: p = 0.037; Gap In Noise test - GIN threshold: p = 0.046; Duration Pattern Test - DPT: p = 0.053), but not for perceived listening behaviours and cognitive abilities. Correlations were found only between perceived listening behaviours and reported mTBI symptoms for parents (p =0.014) and children (p =0.002). Conclusions Auditory abilities, mostly those related to temporal processing, were affected following mTBI, independently of cognitive abilities. Better identification of auditory processing difficulties following mTBI will improve treatment and resource allocation for children.

The evaluation of auditory processing skills and late latencies in children with ventilation tube history

Objective(s): This study aims to evaluate the changes in temporal auditory processing skills in children who underwent bilateral ventilation tube insertion (VTI) due to Otitis Media with Effusion (OME) and the effect of these changes on speech comprehension in noisy environments. MethodsThis is a case-control study. In total, 60 children were included in the study in two groups. The control group included 30 children aged 11 to 15, who had normal hearing thresholds and normal immitancemetric evaluation, and were not diagnosed with OME. The study group included 30 children, aged 11–15 who underwent bilateral VTI surgery after their diagnosis of OME during the ages of 3–10 and currently had normal hearing thresholds and normal immitancemetric values. Each group underwent the Turkish Matrix Test (TMT), Random Gap Detection Test (RGDT), Frequency Pattern Test (FPT), Duration Pattern Test (DPT), and Cortical Auditory Evoked Potential Test (CAEP). ResultsWhen the temporal processing tests (FPT, DPT, RGDT) were compared, a significant difference was obtained between the study group and the control group (p < 0.05). With the TMT, significantly lower scores were obtained in the study group compared to the control group (p < 0.01). In addition, the latency values in the cortical auditory evoked potential test were longer in the study group compared to the control group, but these results were not statistically significant (p > 0.05). ConclusionAs a result of the study, it is concluded that the central auditory processing skills were affected in children with a history of bilateral VTI due to OME. Temporal processing tests, Turkish Matrix Test and Cortical Auditory Evoked Potential tests can be recommended as reliable and easily applicable tests, together with traditional hearing test methods in children with a history of OME, in order to evaluate comprehension skills in classroom noise.

Investigation of the Effect of Pediatric Serous Otitis Media on Music Perception and Auditory Processing

Abstract Background: Otitis media (OM) with effusion is a common early childhood condition. While the auditory nervous system develops, exposure to inconsistent auditory stimuli can affect sound perception. It is also known that musical perception may be affected, as well as auditory processing, by serous OM (SOM). Aims and Objectives: Our study aimed to evaluate the musical perception and auditory processing of children with normal hearing who had a history of SOM in early childhood. Materials and Methods: Children aged 8–13 years with (n = 20) and without (n = 22) a history of SOM in early childhood who were determined to have normal hearing by audiological tests were included. The Montreal Battery of Evaluation of Musical Abilities (MBEMA) was used to assess their musical perception; the frequency pattern test (FPT), the duration pattern test (DPT), and the gap detection (GD) were applied to evaluate their temporal processing skills. The Turkish version of the Children’s Auditory Performance Scale (CHAPS) was used for subjective evaluations. Results: A statistically significant difference between the groups was found in the scores of the melody subtest of the MBEMA (P = 0.028), in FPT (P = 0.007), in DPT (P = 0.038), and in CHAPS scores (P = 0.028), but no statistically significant difference was noted between GD values (P &gt; 0.05). A moderate (0.324) positive correlation was found between the melody test and the FPT. A moderate (0.316) positive correlation was found between the FPT and CHAPS results. Conclusion: OM, common in early childhood, may negatively affect music perception and auditory processing skills.

Utility of deficit-specific computer-based training on children with temporal processing deficit.

Children with temporal processing deficits struggle to detect and discriminate syllables, phonemes, and stress patterns in speech. To overcome these deficits, computer-based auditory training programs have been widely used as one of the rehabilitation alternatives in recent years. The present study aimed to examine the usefulness of one such computer-based temporal processing training (CBTPT) module on children with temporal processing deficits. Sixteen children (8-15years) with temporal processing deficits were enrolled in the study, further divided into active (CBTPT) and placebo (placebo training) groups. Further, 8 typically developing children (no training) were enrolled as a comparison group. The auditory outcome measures included Duration Pattern Test (DPT), Gap Detection Test (GDT), Dichotic CV (DCV), and Speech-in-Noise-Indian English (SPIN-IE) assessed before and after training for all three groups. Wilcoxon-sign rank test showed a statically significant difference between pre and post-test scores of DPT, GDT, and SPIN (p < 0.001) except DCV among the active group. However, no significant differences were noted in the pre and post-test scores among the placebo and TD groups. Mann Whitney U test showed a significant difference in DPT and SPIN post-training scores between active and placebo groups; active and TD group; placebo and TD group. From the above finding, it is inferred that the CBTPT module is useful among children having temporal processing deficits.

The development of the Questionnaire of (Central) Auditory Processing: a screening tool of auditory processing

ObjectiveThe aim of this study was to develop a screening questionnaire for auditory processing disorder (APD) targeted for the Maltese pediatric population.MethodThe questionnaire consisted of 25 close-ended questions in which parents rated their child's listening skills. The data was collected from 101 typically developing Maltese bilingual children and 30 children forming a clinical group, aged between 7;00 and 9;11 years.ResultsThe tool was found to be highly reliable with an internal consistency of 0.92 and test-retest reliability of 0.94. Significant differences emerged between normal and clinical groups (p = &amp;lt; 0.001). Correlational analysis demonstrated a significant correlation between the Questionnaire of (Central) Auditory Processing (QCAP) and the speech-in-noise test, Duration Patterns Test and tests of dichotic listening.ConclusionThe QCAP is potentially an effective screening tool for highlighting listening difficulties in Maltese children at risk of having APD.

Perception of Pitch and Duration Pattern of Vowel /a/: A Comparison across Age and Gender in 5 to 9 Years Old Children

Abstract Objectives The present study aimed to develop pitch pattern test (PPT) and duration pattern test (DPT) using vowel and investigate the temporal ordering skills among typically developing children aged 5 to 9 years across genders. The study compared the performance of children on these tests across different age groups and gender. The study also investigated the relationship between performance on the DPT and PPT tasks using the vowel /a/. Materials and Methods Two verbal stimuli tests, DPT and PPT, were developed. For DPT, the vowel /a/ was used at 246 Hz and had two different durations of 500 and 250 ms for long and short stimuli, respectively, with a 300-ms interstimulus interval. For PPT, the vowel /a/ was used at 220 Hz for “low” stimuli and 261 Hz for “high” stimuli, both lasting 500 ms, with a 300-ms interstimulus duration and a 6-second intersequence duration.A cross-sectional study design was utilized in the study. A total of 100 typically developing school children aged between 5 and 9 years were divided into five age groups, each consisting of 10 males and 10 females. All children passed a hearing screening at 25 dB HL from 250 Hz to 4,000 Hz and had an average or above-average academic performance as reported by their teacher. All the children were tested using the developed tests. The order of administration of DPT and PPT was randomized. Children were instructed to listen to the sequence of vowel presentations and hum them in the same order. Results There was no significant difference between scores of males and females across all the age groups. On both tests, there was a significant improvement in the performance of the children with increase in age. There was a strong overall correlation between scores of DPT and PPT. Conclusion Both DPT and PPT, utilizing vowels as stimuli, did not exhibit a ceiling effect. This study highlighted a robust correlation between the two tests.

Comparison of listening efforts in typically developing children and children with central auditory processing disorders

ObjectivesThe study's main objective was to compare Listening Effort (LE) in children with central auditory processing disorder [(C)APD] and typically developing children in quiet and at −2 and −6 dB SNR conditions. And to determine the relationship between LE and auditory processing abilities in children with (C)APD. MethodsThe study included 30 children (15 typically developing children and 15 diagnosed with (C)APD) aged 10–12 years. LE was measured using a dual-tasking paradigm. The primary task required the child to repeat the words. The second task required the child to click the mouse based on the image displayed on the laptop's screen. The primary task was done at quiet, −2 dB SNR, and −6 dB SNR conditions. LE was correlated with dichotic CV, duration pattern test, speech perception in noise - Indian English, and gap detection test in children with (C)APD. ResultsA mixed ANOVA was performed with LE in various conditions as the within-subject factor and group as the between-subject factor for both repetition and reaction time. The study found that LE repetition and reaction time had a significant main effect across conditions and groups. The correlation results revealed a significant relationship between LE reaction time with dichotic scores and GDT thresholds only at −2 dB SNR and −6 dB SNR conditions. There was no significant correlation between other auditory processing abilities and LE under different conditions, such as quiet, SPIN-IE, and DPT at −2 dB SNR and −6 dB SNR. ConclusionThe study emphasizes the importance of cognitive abilities for adequate listening comprehension in challenging situations. As a result, assessing LE in this population may provide additional information for developing therapeutic activities and assisting the child in overcoming listening difficulties.

Does migraine affect central auditory processing abilities?

ObjectiveMigraine is a neurological disease associated with an altered cortical excitability level. Several studies have investigated the relationship between migraine and central auditory processing (CAP), with deficits in CAP being common among migraine patients. However, studies on the factors affecting these CAP changes observed in migraine patients are still few and controversial. This study aims to investigate CAP changes in migraine patients with Duration Pattern Test (DPT) and Frequency Pattern Test (FPT), which have not been used in previous studies. MethodsSixty subjects were divided into two groups and one migraine subgroup: control group, twenty normal healthy subjects, fourty subjects diagnosed with migraine. They were evaluated using the CAP test including DPT and FPT. To identify the variables and possible effects of the variables, a questionnaire describing the characteristics of migraine features was administered to participants with migraine. ResultsNo significant difference was found the between the control and study group in CAP tests scores. No significant correlation was found between migraine characteristics and CAP tests scores. Males had significantly higher FPT scores in both ears than females (p<0.05). Significant statistical negative correlation was found between age and FPT scores for both ears and left DPT scores (p<0.05). ConclusionAlthough migraine patients generally showed lower CAP ability than the control group, no significant difference was observed between them. This was also valid for subgroups of migraine. However, as age increased in the migraine group, a significant decrease in CAP performance was observed. It was observed that male migraine patients had better CAP ability, especially FPT scores. Migraine may affect performance in CAP depending on gender and age factors.

Normative values for tests of central auditory processing disorder in children aged from 6 to 12 years old

IntroductionCentral auditory processing disorders (CAPD) can significantly affect the daily functioning of a child, and the first step in determining whether rehabilitation procedures are required is a proper diagnosis. Different guidelines for making diagnoses have been published in the literature, and in various centers normative values for psychoacoustic tests of CAPD have been used internally. The material presented in this paper is based on more than 1000 children and is the largest collection so far published. The aim of this study is to present normative values for tests assessing CAPD in children aged 6 to 12 years, divided by age at last birthday. MethodWe tested 1037 children aged 6 to 12 years who were attending primary schools and kindergartens. The criteria for inclusion were a normal audiogram, intellectually normal, no developmental problems, and no difficulties in auditory processing. To evaluate auditory processing all children were given three tests on the Senses Examination Platform: the Frequency Pattern Test (FPT), Duration Pattern Test (DPT), and Dichotic Digit Test (DDT). ResultsThe results from 1,037 children allowed us to determine normative values for FPT, DPT, and DDT in seven different age groups (6 through to 12 years). We developed a newapproach, based on quantile-based norms, to determine normative values in each group. Three categories – average, below-average, and above-average – allow for a broader but more realistic interpretation than those used previously. We compare our results with published standards. ConclusionsOur study is the largest normative database published to date for CAPD testing, setting a standard for each child by age in years. We used the Senses Examination Platform, a universal tool, to unify standards for the classification of CAPD. Our study can serve as a basis for the development of a Polish model for the diagnosis of CAPD.

Investigation of central auditory processing performance in individuals with and without stuttering

BackgroundDifferences in core auditory processing abilities, such as sound timing, frequency discrimination, auditory perception, and auditory memory, have been suggested in stutterers, despite the fact that the precise origin of stuttering is not entirely understood. It is suggested that these differences may play a role in the development of stuttering. The aim of our study is to assess the temporal central auditory processing performance in individuals with stuttering and compare it to individuals without stuttering to uncover potential differences stuttering and compare it to individuals without stuttering to reveal potential differences. MethodIn current study, a total of 60 right-handed participants between the ages of 8 and 17 were included, divided into two balanced groups based on age, education, and gender: individuals with stuttering (n = 30) and individuals without stuttering (n = 30). All participants underwent the Frequency Pattern Test, Duration Pattern Test, and Gaps-In-Noise test. ResultsIndividuals who stutter showed lower performance in the gap detection threshold and the percentage of total correct gap identification parameters of the Frequency Pattern Test, Duration Pattern Test, and Gaps-In-Noise test compared to fluent speakers. ConclusionsThe findings indicate a potential relationship between stuttering and central auditory processing. In this context, incorporating central auditory processing measures into the assessment and therapy processes for stuttering may enhance the likelihood of obtaining more accurate results.

Adults With Cochlear Implants: Residual Hearing, Musical Perception, and Temporal Skills.

The main purpose of the study is to investigate whether the presence of residual hearing before cochlear implantation has an effect on temporal pattern recognition skills and musical perception in adults. The study included adults with cochlear implants who were between the ages of 20 and 45 years. Adults with cochlear implants were divided into two groups: absent (n = 20) and available (n = 20) groups according to residual hearing before implantation. Frequency Pattern and Duration Pattern tests were applied to evaluate temporal pattern recognition, and the "Music-Related Quality of Life Questionnaire" was applied to evaluate musical perceptions. There were no statistically significant differences between the groups in terms of cochlear-implanted hearing thresholds and speech recognition scores, musical perception, and musical activities, according to their residual hearing. On the other hand, the frequency and duration pattern recognition skills were statistically significantly better in adults with residual hearing. Also, statistically significant correlations were obtained in terms of temporal skills and musical perception subskills. The presence of residual hearing before cochlear implantation may affect temporal auditory processing skills. It is concluded that the integration of cochlear implants may affect temporal processing skills in adults as well as quality of life. It is recommended that experts be aware of this issue and pay attention to residual hearing.

The Effect of a Non-Surgical Adhesive Bone Conduction Device on Temporal Processing Performance in Adults with Single Sided Deafness: A Pilot Study.

There is a dearth of information on the effects of bone conductive devices on temporal processing in individuals with single-sided deafness (SSD). This study investigates the effect of an adhesive bone conductive device on temporal processing in adults with SSD. A prospective cohort study of temporal processing in adults with SSD was undertaken. Outcome measures were the pitch pattern test (PPT) and the duration pattern test (DPT) scores, sound field pure tone audiometric (PTA) averaged hearing thresholds, and word recognition scores (WRS). These were measured under 3 conditions: unaided in quiet, unaided in noise, and aided in noise. Eight SSD novice hearing amplification users were recruited. The adhesive bone conduction device (BCD) resulted in a statistically-significant improvement (Wilcoxon signed ranks test, P = .018) in median [interquartile range (IQR)] PPT score, 65% (IQR = 35.5), and DPT score, 38% (IQR = 42.5) in noise. Adults with SSD demonstrated improved temporal processing scores with masking of the normal-hearing ear when using an adhesive BCD placed behind the deafened ear.

Processamento auditivo central e processamento fonológico em bilíngues do português brasileiro - inglês

ABSTRACT Purpose: to compare temporal auditory processing (temporal ordering) and phonological processing skills in bilingual and monolingual subjects. Methods: 100 undergraduate and postgraduate university students divided into a bilingual group (BG; n = 50) and a monolingual group (MG; n = 50). The study assessed the two groups’ phonological processing skills (phonological awareness, working memory - phonological loop, and rapid lexicon access) and temporal auditory processing skills (Frequency Pattern and Duration Pattern Tests). The Mann-Whitney test (p = 0.05) was used for statistical analysis. Results: BG performed better than MG in phonological awareness and phonological working memory tasks - nonword repetition and rapid naming tasks, except for color naming, and the two auditory processing tests. Conclusion: Bilinguals performed better on phonological and auditory tests. These skills help them identify and discriminate variations in the phonology of both languages, influencing their performance.

Temporal Ordering and Auditory Resolution in Individuals with Sensorineural Hearing Loss.

Introduction Peripheral hearing loss, besides causing inadequate auditory input, can lead to distortions in the tonotopic auditory map and reorganization of neural networks. Therefore, the processing of temporal aspects of a sound stimulus and, consequently, the effectiveness of human communication can be negatively impacted. Objective To test the temporal ordering and auditory resolution of people with mild and moderate sensorineural hearing loss and to compare them with the those of people with normal hearing. Methods A total of 19 right-handed individuals aged 16 to 59 years with mild to moderate postlingually acquired symmetric bilateral sensorineural hearing loss participated in the study. They were submitted to frequency and duration pattern tests and a random gap detection test. Results The mean correct response rate in the frequency pattern test was of 66.3%, and, in the duration pattern test, 71.7%. The mean threshold in the random gap detection test was of 14.1 ms. A comparison with the criteria established for normal subjects without peripheral hearing loss revealed that more than half the subjects had abnormal results in the temporal ordering test, while a smaller fraction had reduced temporal resolution. Conclusions The performance of the subjects with acquired sensorineural hearing loss was poorer than that of the participants without peripheral hearing loss. Their results on the temporal ordering test were also poorer than in the temporal resolution test, demonstrating the importance of analyzing both these auditory skills in people with peripheral hearing loss.

A Survey on Screening and Diagnostic Criteria of Auditory Processing Disorders in India.

The current study aimed to determine the criteria used for screening and diagnosing cases with central auditory processing disorders (CAPD) in India. A cross-sectional questionnaire-based survey design was used in the present study. A questionnaire was developed to determine the criteria used for screening and diagnosing CAPD across clinics in India. Responses were obtained from 83 participants from all over India. Results indicated that 78% of respondents were currently doing CAPD evaluation. In that, the majority of respondents (63%) had a predetermined minimum battery that was relatively adaptable depending on the case history and age of the patient. In screening, most respondents used a screening questionnaire (SCAP, 75%) and a screening test (STAP, 60%). In the diagnostic protocol, the most used tests by the respondents were masking level difference (MLD), repetition of words (RW), gap detection test (GDT), pitch pattern test (PPT), speech perception in noise (SPIN), digit span test (DST), dichotic digit test (DDT), binaural fusion test (BFT), auditory brainstem response (ABR), dichotic CV test (DCVT), and duration pattern test (DPT). The current study's result will help professionals choose the minimum test battery for diagnosing CAPD.

Auditory processing disorders in children – diagnosisand management

Introduction: Auditory Processing Disorders (APD) is a syndrome characterized by impairment of the perception of soundsverbal and non-verbal ones, and weakening cognitive abilities such as auditory attention and auditory memory. This symptoms occur despite correct functioning of the peripheral part of the organ of hearing. Aim: A review of the current literature on diagnostic criteria of APD and its subtypes, clinical symptoms in children, diagnostic procedures and methods and therapeutic interventions. Methods: The study was based on the guidelines of the British Audiological Society (BSA), the guidelines of the American Speech, Language and Hearing Society (ASHA) as well as a literature review in the PubMed database. Results: APD is divided into developmental (without an established cause), acquired (with an established cause) and secondary (a consequence of long-term peripheral hearing loss). Symptoms that indicate the likelihood of APD in schoolaged children include: poor school performance, problems with learning to read and write and understanding speech, difficulties in repeating and remembering information given by hearing and maintaining attention on the spoken word. APD diagnosis should be made by a specialist in audiology and phoniatrics based on a full battery of tests and consultations with a speech therapist, psychologist and pedagogue. The set of behavioral diagnostic tests should include both verbal and non-verbal tests, from at least three groups of tests: dichotic (e.g. dichotic digit test; DDT), evaluating temporal aspects of hearing (e.g. Frequency Pattern Test; FPT and Duration Pattern Test; DPT ) and low redundancy speech tests. The diagnosis can be made when the child is at least 7 years old, the result is below the norm in at least two tests evaluating different auditory processes and the child has previous been excluded from intellectual disability and autism spectrum disorders. The therapeutic procedure is based on active auditory training, specific for the deficit shown in the tests. It is important to improve the acoustic environment at school (FM systems) and to treat comorbidities. Conclusions: Diagnostics and therapy of APD requires a highly qualified team of specialists and should be carried out in centers specially prepared for this purpose.

Assessment of auditory processing skills in adolescents with cleft lip and palate

Objective Auditory deprivation due to middle ear defects caused by congenital malformations in the cleft lip and palate population may be a long-term risk factor for auditory processing disorder. The aim of the study is to assess the auditory processing skills in adolescents with cleft lip and palate by considering also maturation effect. Methods Thirty (10–17 years old) adolescents with operated, non-syndromic cleft lip and palate and thirty (10–17 years old) adolescents with normal development were included in the study. While both groups had bilateral normal peripheral hearing levels, study group had a history of chronic otitis media due to congenital malformations. In addition, participants were also evaluated in subgroups, under and over the age of 12, based on 12 years of age at which adult-like responses were obtained for auditory processing. Frequency pattern, duration pattern and Turkish matrix tests were used to assess auditory processing skills. Result The mean scores of the study group in frequency pattern, duration pattern and Turkish matrix tests were lower than the control group (p = 0.000). When the participants were evaluated as under and over the age of 12, while under the age of 12 showed lower performance than over the age of 12 for the study group (p < 0.05), this difference was not observed in the control group (p > 0.05). Conclusion Adolescents with cleft lip and palate may be disadvantaged in their auditory processing skills compared to their peers and they still may not catch up with their peers, even if improvement is observed with the maturation effect.

The Relationship between P300 and Central Auditory Processing Test Result.

Central auditory processing (CAP) refers to the perceptual processing of auditory inputs in the central nervous system and includes a series of auditory skills such as sound localization, auditory pattern recognition, and temporal sequencing which is a component of temporal processing. This skill can be assessed by frequency pattern test (FPT) and duration pattern test (DPT). Auditory attention is another skill that contributes to the CAP and can be analyzed by the P300. This study assesses the relationship between the P300 latency and the CAP test results of individuals with normal hearing. An experimental study was used in which the determined tests were applied to the participants. Thirty-four individuals with normal hearing between the ages of 20 and 40 years were included in the study. P300, FPT, and DPT were applied to the participants. The Spearman correlation test and Mann-Whitney U test were used for analysis. There were significant moderate and strong-level negative correlations between P300 latency and the scores obtained from frequency pattern and DPT (p < 0.01). We also analyzed whether P300 latency and frequency pattern and DPT scores differed according to gender and, as a result, did not find significant relationship (p > 0.05). We observed that frequency pattern and DPT scores decreased as P300 latency increased. We propose that these results could contribute to the diagnosis and follow-up process of CAP disorder by allowing P300 and CAP tests to be cross-checked.

Assessment of temporal auditory processing in individuals with misophonia

Objective Misophonia is characterised by abnormal reactions to certain sounds such as sounds of eating, breathing, nose sniffing. Misophonia can be seen in individuals with normal hearing or hearing loss. The aim of this study to evaluate central auditory processing in misophonia patients with temporal processing tests, such as the Frequency Pattern Test (FPT), Duration Pattern Test (DPT), and Gaps-in-Noise Test (GIN). Methods Thirty patients with misophonia and 30 healthy control subjects were included in this study. The pure tone audiometry test, tympanometry test, and acoustic reflex test were administered to all participants. The DPT, FPT, and GIN tests were conducted with all participants. Results There was no significant difference in the DPT scores between the two groups for both ears (p > .05). There was no significant difference in the FPT scores between the two groups for both ears (p > .05), and there was no significant difference in the GIN scores and GIN threshold (p > .05). Conclusions There was no difference between the healthy individuals and the misophonia patients when the temporal process of central auditory processing was evaluated.
