BACKGROUND Neurogenic stuttering (NS) is the most frequently occurring acquired form of stuttering in children and adults. This form of stuttering is primarily caused by neurological incidents. Owing to controversies with regard to similarities between developmental stuttering (DS) and NS symptomatology, differential diagnosis is problematic. Differential diagnosis will guide the appropriate ma...

Objective The basal ganglia are a group of structures that act as a cohesive functional unit. They are situated at the base of the forebrain and are strongly connected with the cerebral cortex and thalamus. Some speech disorders such as stuttering can resulted from disturbances in the circuits between the basal ganglia and the language motor area of the cerebral cortex. Stuttering consists of b...

We recently encountered a case of stuttering priapism in a 41-year-old patient with neurosyphilis. Priapism very rarely has a neurogenic cause, and to our knowledge, priapism caused by neurosyphilis has not been reported previously in the literature. Our aim was to report this case and systematically review the related literature.

BACKGROUND Approximately 1% of children and adolescents, 0.2% of women, and 0.8% of men suffer from stuttering, and lesser numbers from cluttering. Persistent speech fluency disorders often cause lifelong problems in communication and social participation. METHODS In an interdisciplinary, evidence and consensus based clinical practice guideline, the current understanding of the nature, identi...

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...

Although the cause of stuttering is unknown, there is strong evidence for it being a neuromotor disorder characterised by an abnormality of higher control encompassing not only speech but other motor systems. The aim of this exploratory study was to look for the presence of non-speech/language deficits--in particular, visuomotor and visuoperceptual deficits--in persons who stutter. Twelve moder...

We present a 69 year-old man with hypertension who developed the sudden onset of horizontal binocular diplopia and stuttering of speech. On examination, bilateral exotropia (i.e. 'wall-eyed') was observed in the primary position. Attempted horizontal saccades revealed bilateral internuclear ophthalmoplegia; all consistent with the wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) syndro...

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...
