UNLABELLED The purpose of this review is to determine what neural mechanisms may be dysfunctional in stuttering. Three sources of evidence are reviewed. First, studies of dynamic inter-relationships among brain regions during normal speech and in persons who stutter (PWS) suggest that the timing of neural activity in different regions may be abnormal in PWS. Second, the brain lesions associated...

UNLABELLED Multiple studies have reported both functional and neuroanatomical differences between adults who stutter and their normally fluent peers. However, the reasons for these differences remain unclear although some developmental data suggest that structural brain differences may be present in school-age children who stutter. In the present study, the corpus callosum of children with pers...

In this study, we documented the effects of a 3-week, intensive stuttering treatment program on overt and covert symptoms of stuttering and participants’ levels of social anxiety. This study was a preliminary report in which we used a single-group pretestposttest design to analyze outcomes data with reference to each participant individually and described general group trends. Researchers gave ...

Though many causes have been considered from mental or anatomical viewpoint, the mechanism of stuttering is not known yet. One candidate for the stuttering occurrence is a dysfunction of basal ganglia. However the detailed relation between the basal ganglia dysfunction and the stuttering is not understood. In this study, based on anatomical, physiological and clinical evidences, we propose a fu...

PURPOSE This study investigated attitudes of nonstuttering preschool and kindergarten children toward peers who stutter in order to identify differences by age groups and better understand the genesis of stuttering attitudes. The study also examined the use of a new stuttering attitudes instrument designed for use with young children. METHOD The newly developed Public Opinion Survey on Human ...

CONTEXT AND OBJECTIVE Stuttering is a complex disease that influences occupational, social, academic and emotional achievements. The aim of this study was to correlate the stuttering severity index with speaking rates of mothers and children. DESIGN AND SETTING Cross-sectional study, at the child rehabilitation clinics of Tehran city. METHODS 35 pairs of mothers and their children who stutt...

Although developmental stuttering has been extensively studied with structural and task-based functional magnetic resonance imaging (fMRI), few studies have focused on resting-state brain activity in this disorder. We investigated resting-state brain activity of stuttering subjects by analyzing the amplitude of low-frequency fluctuation (ALFF), region of interest (ROI)-based functional connecti...

BACKGROUND AND OBJECTIVES Extensive research documents ubiquitous negative attitudes towards stuttering, but when and how they develop is unclear. This non-experimental, comparative study examined US and Turkish preschoolers to explore the origin of stuttering attitudes cross-culturally. METHOD The authors compared stuttering attitudes of 28 US and 31 Turkish non-stuttering preschoolers on En...

UNLABELLED The purpose of this study was to examine the impact that stuttering has on job performance and employability. The method involved administration of a 17-item survey that was completed by 232 people who stutter, age 18 years or older. Results indicated that more than 70% of people who stutter agreed that stuttering decreases one's chances of being hired or promoted. More than 33% of p...
