The old saying by Van Riper (with a nod to Winston Churchill), that stuttering is a riddle wrapped in a mystery inside an enigma, is well known. While it would be preposterous for any of us to state that, 40 years later, we now have solved the riddle, we can say with a great degree of confidence that advances in scientific inquiry have brought us closer to understanding the factors that may tri...

Persistent developmental stuttering (PDS) is a speech disorder that impairs communication skills. Despite extensive research, the core causes of PDS are elusive. Converging evidence from task-induced neuroimaging methods has demonstrated the contributions of the basal ganglia and the cerebellum to PDS, but such task-state neuroimaging findings are often confounded by behavioral performance diff...

objectives: it has been noted that stuttering is more prevalent in bilinguals than in monolinguals. the similarities of the languages involved have been mentioned to justify the difference between stuttering prevalence among bilingual and monolingual speakers. the aim of this study is to investigate the effect of language similarities on prevalence of stuttering among kurdish-farsi bilingual st...

Persistent developmental stuttering is characterized by speech production disfluency and affects 1% of adults. The degree of impairment varies widely across individuals and the neural mechanisms underlying the disorder and this variability remain poorly understood. Here we elucidate compensatory mechanisms related to this variability in impairment using whole-brain functional and white matter c...

BACKGROUND quality of life. AIM to verify the influence of the readiness of speech--regarding affective, behavioral and cognitive reactions--over the life quality of fluent individuals and those with persistent developmental stuttering (PDS). METHOD 40 adults divided in two groups, paired by gender and age. The research group (GI) consisted of 20 individuals with PDS, with no other associat...

Gagap (stuttering) adalah suatu gangguan dalam berbicara yang ditandai dengan terjadinya pengulangan atau perpanjangan dan penghentian bunyi suku kata. dapat diderita oleh segala usia, terutama pada usia anak-anak (developmental stuttering) menyebabkan kefasihan keterlambatan hal berbicara. Insiden seseorang pernah mengalami gagap hidupnya sekitar 5% populasi dunia 60 juta orang. Studi menunjuk...

Evidence for genetic factors in persistent developmental stuttering has accumulated over the past four decades, and the genes that underlie this disorder are starting to be identified. The genes identified to date, all point to deficits in intracellular trafficking in this disorder.

PURPOSE This study experimentally investigated behavioral correlates of emotional reactivity and emotion regulation and their relation to speech (dis)fluency in preschool-age children who do (CWS) and do not (CWNS) stutter during emotion-eliciting conditions. METHOD Participants (18 CWS, 14 boys; 18 CWNS, 14 boys) completed two experimental tasks (1) a neutral ("apples and leaves in a transpa...

UNLABELLED Neuroimaging studies have indicated that persistent developmental stuttering (PDS) may be associated both with an abnormality in white matter of left-hemispheric speech areas and a right-hemispheric hyperactivity. The latter may compensate for the deficient structural connectivity in the left hemisphere. To investigate the effects of stuttering therapy on brain activity nine male adu...
