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

Background: Differences 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. Method: In 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. Results: Individuals 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. Conclusions: The 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.

Background and Aim: Path integration refers to the capability of utilizing self-motion information produced by one’s own bodily movements to accurately determine and maintain one’s position in space. Typically, path integration mechanisms come into play when visual information is limited or absent. The objective of this study was to develop a path integration test that relies solely on self-motion cues derived from body movements, without the involvement of visual cues. Methods: The study involved 157 volunteers (86 females and 71 males) aged between 18 and 70 years. Participants were asked to walk on a coordinated ground with their closed eyes and follow the six different commands. They were, after that, requested to return their initial position. Movement time was manually measured by the stopwatch. The distance between the original reference point and estimated starting point was recorded. Results: The second command that showed the lowest standard deviation out of the six commands given to the participants was observed as the more reliable test among the other commands (47.51±33.75). In addition, the completion time of the second command increased with increasing age (p[removed]

Introduction: Multiple sclerosis (MS) is an autoimmune disease that can affect balance, gait, and improve fall risk. The aim of this study was to investigate peripheral vestibular system involvement in MS and associations with the disease severity. Methods: Thirty-five adult patients with MS and 14 age- and gender-matched healthy controls were evaluated using video head impulse test (v-HIT), cervical vestibular evoked myogenic potential (c-VEMP), ocular vestibular evoked myogenic potentials (o-VEMPs), and sensory organization test (SOT) of computerized dynamic posturography (CDP). The results of both groups were compared, and association with EDSS scores was evaluated. Results: There was no significant difference between the groups regarding v-HIT and c-VEMP results (p > 0.05). There was no association of the v-HIT, c-VEMP, and o-VEMP results with EDSS scores (p > 0.05). There was no significant difference between the o-VEMP results of the groups (p > 0.05) except for N1-P1 amplitudes (p = 0.01). The amplitudes of N1-P1 were significantly lower in the patients compared to controls (p = 0.01). There was no significant difference between the SOT results of the groups (p > 0.05). However, significant differences were found within and between groups when the patients were categorized according to their EDSS scores with a cutoff point of 3 (p < 0.05). There were negative correlations between the EDSS scores and composite (r = -396, p = 0.02) and somatosensory (SOM) scores (r = -487, p = 0.04) of CDP in the MS group. Conclusion: Although central and peripheral balance-related systems are affected in MS, the impact of disease on the peripheral vestibular end organ is subtle. In particular, the v-HIT, which was mentioned previously as a detector of brainstem dysfunction could not be a reliable tool in the detection of brainstem pathologies in MS patients. The o-VEMP amplitudes may be affected in the early stages of the disease, possibly due to the crossed ventral tegmental tract, oculomotor nuclei, or interstitial nucleus of Cajal involvements. An EDSS score >3 seems a cutoff level indicating abnormalities in balance integration.

Background: Tinnitus is the perception of sound, which is not generated by external stimulus. Due to its clinical heterogeneity, lack of objective measurements and accompanying symptoms, a gold standard treatment, i.e., effective for every patient has not been established yet. The aim of the present study was to assess the prevalence and characteristics of tinnitus, disease, and lifestyle factors associated with tinnitus. Materials and Methods: Data were obtained from a total of 224 patients (mean age 46.21 ± 12.65), 141 men and 83 women, who attended the audiology department between 2015 and 2021. Results: We found that the tinnitus pitch perception (PP) of males was significantly higher than females (P < 0.001). In addition, we observed a significant positive correlation between tinnitus PP and tinnitus loudness perception (P < 0,005). 12.1% (27 patients) of the individuals included in the study had metabolic disorders (Vitamin D deficiency, diabetes, and cholesterol). Fifty-four percent (121 patients) of the individuals included in the study had normal hearing. Conclusions: Metabolic and cardiovascular diseases should be taken into account for tinnitus anamnesis. The amount of tinnitus patients with normal hearing is also notable.
