Its cause is not fully known. Sensory gating is an essential part of information processing and developing an appropriate behavioral response in the brain. Psychological, social, and learning-related factors together with sensorymotor variables play an important role in ensuring fluent speech. Sensory gating protects the brain from overload by filtering the redundant or potentially irrelevant information from the continuous and intensive stream of information. A lack of sensory gating for auditory stimuli may lead to disturbed auditory signal processing and auditory feedback and result in loss of speech fluency. Our aim in this study was to evaluate the state of sensory gating in children and adolescents with developmental stuttering using P50 suppression to test our hypothesis that sensory gating may be disturbed in stuttering. Method: A total of 20 stuttering children and adolescents in 7-18 age group and 20 age-and sex-matched healthy controls with no speech problems were included in the study. All children underwent psychiatric evaluation by a pediatric psychiatrist. Patients with psychiatric, neurological or chronic disease, those who had a history of using medication that could affect the central nervous system and children with a family history of schizophrenia were excluded from the study. P50 suppression was then recorded with an electroencephalogram (EEG). Statistical analysis was performed using the SPSS package software program. The Mann-Whitney U test was used to compare the P50 values of the two groups and p value <0.05 was considered significant for all analyses. Results: The mean age for the children and adolescents included in the study was 11.8 +/- 2.7 years and the age stuttering started was 4.6 +/- 1.1 years. There were 16 males (80%) and 4 females (20%) in both groups. There was no statistically significant difference between the P50 amplitude, latency and P50 suppression ratios of the two groups. Conclusion: The results of this study have shown no association between P50 and stuttering in children and adolescents. However, this first study evaluating sensory gating in children and adolescents should be repeated with prepulse inhibition, another test used to evaluate sensory gating, on larger samples and in different age groups.eninfo:eu-repo/semantics/closedAccessStutteringsensory gatingP50Article1932412462-s2.0-70350043050N/A95687WOS:000271692600006Q4
