Objective: Stuttering is a speech disorder, where speech şuency is disturbed by the involuntary repetition and prolongation of words and syllables. 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 şuent 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 şuency. 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
