Introduction Over the past decade several functional neuroimaging studies in developmental stuttering have been published. In comparison to non-stuttering volunteers, these studies revealed that adults who stutter show overactivation in areas such as the cerebellum, supplementary motor area (SMA), right frontal operculum (RFO), and the right insula. This overactivation mostly occurs bilaterally...

Awareness of stuttering is likely to depend upon the development metalinguistic skill discriminate between fluent speech and ability identify one’s own as or stuttered. Presently, little known about these abilities in individuals with Down syndrome (DS). This study investigates whether DS typically developing (TD) children who stutter do not differ their stuttering. The second purpose this disc...

Objectives: Stuttering is one of the most prevalent speech and language disorders. Symptomology of stuttering has been surveyed from different aspects such as biological, developmental, environmental, emotional, learning and linguistic. Previous researches in English-speaking people have suggested that some linguistic features such as word meanings may play a role in the frequency of speech non...

The main feature of stuttering is the disturbance in terms of both timing and fluency of speech inappropriate with the age. This disturbance is characterized with the repetition and prolongation of sounds and syllables. There are two types of stuttering as acquired and developmental. Acquired stuttering may begin suddenly at any age and may be seen rarely due to the adverse effects of drugs. St...

UNLABELLED The possible relation between stuttering and the basal ganglia is discussed. Important clues to the pathophysiology of stuttering are given by conditions known to alleviate dysfluency, like the rhythm effect, chorus speech, and singing. Information regarding pharmacologic trials, lesion studies, brain imaging, genetics, and developmental changes of the nervous system is reviewed. The...

Background and purpose: The acute onset of stuttering in an adult is not uncommon and rarely is caused by ischemic stroke. A neurologist is likely to encounter this presentation and it is important to identify distinguishing features between ischemic stroke and other causes. Adult-onset acquired stuttering is classified as either neurogenic if secondary to brain injury or psychogenic in the abs...

Developmental stuttering is a speech disorder most likely due to a heritable form of developmental dysmyelination impairing the function of the speech-motor system. Speech-induced brain-activation patterns in persons who stutter (PWS) are anomalous in various ways; the consistency of these aberrant patterns is a matter of ongoing debate. Here, we present a hierarchical series of coordinate-base...

Developmental stuttering is a speech disorder that disrupts the ability to produce speech fluently. While stuttering is typically diagnosed based on one's behavior during speech production, some models suggest that it involves more central representations of language, and thus may affect language perception as well. Here we tested the hypothesis that developmental stuttering implicates neural s...

This paper explains the complexity of personal experience of stuttering using self-identity as a lens. It draws on a narrative life history study of five male and two female adults with developmental stuttering. Their experiences of stuttering were subjected to a narrative, interpretive analysis. Two primary self-identity trajectories viz. DisOther and Able were identified in relation to their ...

ABSTRACT Purpose: to develop a screening instrument identify the risk of developmental stuttering in preschoolers. Methods: procedures were divided into two stages: The first one (theoretical), consisted literature review and construction items that make up instrument; second stage (content validation), analysis by judging committee formed 10 speech-language-hearing therapists who work field fl...
