This article presents a critical review of the literature on stuttering, with particular reference to the role of the basal ganglia (BG). Neuroimaging and lesion studies of developmental and acquired stuttering, as well as pharmacological and genetic studies are discussed. Evidence of structural and functional changes in the BG in those who stutter indicates that this motor speech disorder is due, at least in part, to abnormal BG cues for the initiation and termination of articulatory movements. Studies discussed provide evidence of a dysfunctional hyperdopaminergic state of the thalamocortical pathways underlying speech motor control in stuttering. Evidence that stuttering can improve, worsen or recur following deep brain stimulation for other indications is presented in order to emphasize the role of BG in stuttering. Further research is needed to fully elucidate the pathophysiology of this speech disorder, which is associated with significant social isolation. date: 2014-10-17 official_url: http://dx.doi.org/10.3389/fnhum.2014.00884 vfaculties: VFBRS oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: Journal Article, Review verified: verified_manual elements_source: PubMed elements_id: 998747 doi: 10.3389/fnhum.2014.00884 language_elements: ENG lyricists_name: Akram, Harith lyricists_name: Tripoliti, Elina lyricists_name: Zrinzo, Ludvic lyricists_id: HAKRA15 lyricists_id: ETRIP70 lyricists_id: LUZRI77 full_text_status: public publication: Front Hum Neurosci volume: 8 article_number: 884 event_location: Switzerland citation: Craig-McQuaide, A; Akram, H; Zrinzo, L; Tripoliti, E; (2014) A review of brain circuitries involved in stuttering.
