Pei-Tzu Tsai, Nan Bernstein Ratner
Purpose: The study examined whether semantic and phonological encoding processes were capacity demanding, involving the central cognitive mechanism, in adults who do and do not stutter (AWS and NS) to better understand the role of cognitive demand in linguistic processing and stuttering. We asked (a) whether the two linguistic processes in AWS are capacity demanding, which can temporally disrupt the processing of a concurrent nonlinguistic task, and (b) whether AWS and NS show similar patterns of temporal disruption in the two processes...

Persistent developmental stuttering is a neurologically based speech disorder associated with cognitive-linguistic, motor and emotional abnormalities. Previous studies investigating the relationship between anxiety and stuttering have yielded mixed results, but it has not yet been examined whether anxiety influences brain activity underlying stuttering. Here, by using functional magnetic resonance imaging (fMRI), we investigated the functional connectivity associated with state anxiety in a syllable repetition task, and trait anxiety during rest in adults who stutter (N=19) and fluent controls (N=19)...

OBJECTIVE: The aim of the study was to investigate inhibitory control by evaluating possible differences in the strength and distribution of the brain activity in a visual Go/Nogo task in children who stutter (CWS) compared to typically developing children (TDC). METHODS: Eleven CWS and 19 TDC participated. Event related potentials (ERP) were recorded using a 64-channel EEG-cap during an equiprobable visual Go/Nogo task. The global field power (GFP) as well as the mean amplitudes in the P3 time frame were compared between groups...

Many forensic STR kits are currently available in the market. The AmpFLSTR® Identifiler® Plus kit, which targets 15 STRs, is commonly used worldwide. The Thai forensic DNA community is built around it in terms of instrument, databases, and interpretation. QIAGEN's IDplex Plus kit targets the same loci, but the PCR cycling time is shorter by about 90min. A direct comparison that assesses forensic parameters and applicability to casework between the two kits has never been carried out. In this study, we performed a direct comparison between the two kits using serial dilutions of two control DNA samples and 60 randomly selected casework samples, including samples taken from improvised explosive devices and terrorist raids...

Massively parallel sequencing (MPS) is on the advent of a broad scale application in forensic research and casework. The improved capabilities to analyse evidentiary traces representing unbalanced mixtures is often mentioned as one of the major advantages of this technique. However, most of the available software packages that analyse forensic short tandem repeat (STR) sequencing data are not well suited for high throughput analysis of such mixed traces. The largest challenge is the presence of stutter artefacts in STR amplifications, which are not readily discerned from minor contributions...

The HomyGene19+14Y System (HG19+14Y) is a PCR-based amplification kit that enables typing of 18 autosomal short tandem repeat (STR) loci (i.e., CSF1PO, D2S1338, D3S1358, D5S818, D6S1043, D7S820, D8S1179, D12S391, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, Penta E, TPOX, TH01, vWA), 14 widely used Y chromosome STR (Y-STR) loci (Y_GATA_H4, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS438, DYS439, DYS456, DYS458, DYS635), and amelogenin. This multiplex system was designed for the simultaneous analysis of amelogenin-Y allele mutation, single-source searches, kinship (including familial searching), mixture profiles, international data sharing, and other forensic applications...

PURPOSE: There is evidence that access to treatment for early stuttering is not available for all who need it. An internet version of the Lidcombe Program for early stuttering (Internet-LP) has been developed to deal with this shortfall. The LP is suitable for such development because it is delivered by parents in the child's everyday environment, with training by a speech-language pathologist. A Phase I trial of Internet-LP Part 1, comprising parent training, is reported here. METHOD: Eight parents of pre-schoolers who stutter were recruited and six completed the trial...

PURPOSE: Network science uses mathematical and computational techniques to examine how individual entities in a system, represented by nodes, interact, as represented by connections between nodes. This approach has been used by Cramer et al. (2010) to make "symptom networks" to examine various psychological disorders. In the present analysis we examined a network created from the items in the Overall Assessment of the Speaker's Experience of Stuttering-Adult (OASES-A), a commonly used measure for evaluating adverse impact in the lives of people who stutter...

Importance: Developmental stuttering is a neuropsychiatric condition of incompletely understood brain origin. Our recent functional magnetic resonance imaging study indicates a possible partial basis of stuttering in circuits enacting self-regulation of motor activity, attention, and emotion. Objective: To further characterize the neurophysiology of stuttering through in vivo assay of neurometabolites in suspect brain regions. Design, Setting, and Participants: Proton chemical shift imaging of the brain was performed in a case-control study of children and adults with and without stuttering...

PURPOSE: Psychosocial disorders have been reported in adults who stutter, especially social anxiety disorder. Social anxiety has been linked to childhood victimization. It is possible that recalled childhood victimization could be linked to psychosocial problems reported in some adults who stutter. METHOD: Participants were 36 adults who stutter and 36 adults who do not stutter (mean age=21.9 years). The Retrospective Bullying Questionnaire was completed for primary school, secondary school and university environments for physical, verbal, relational and cyber bullying...

PURPOSE: The effects of three anti-stigma strategies for stuttering-contact (hearing personal stories from an individual who stutters), education (replacing myths about stuttering with facts), and protest (condemning negative attitudes toward people who stutter)-were examined on attitudes, emotions, and behavioral intentions toward people who stutter. METHOD: Two hundred and twelve adults recruited from a nationwide survey in the United States were randomly assigned to one of the three anti-stigma conditions or a control condition...

PURPOSE: Clinicians working with fluency disorders sometimes see children whose word repetitions are mostly located at the end of words and do not induce physical tension. Prior studies on the topic have proposed several names for these disfluencies including "end word repetitions", "final sound repetitions" and "atypical disfluency". The purpose of this study was to use phonological analysis to explore the patterns of this poorly recognized fluency disorder in order to better understand its specific speech characteristics...

PURPOSE: Developmental stuttering may be associated with diminished psychological well-being which has been documented from late childhood onwards. It is important to establish the point at which behavioural, emotional and social problems emerge in children who stutter. METHODS: The study used data from the Millennium Cohort Study, whose initial cohort comprised 18,818 children. Analysis involved data collected when the cohort members were 3, 5 and 11 years old...

PURPOSE: The purpose of this study was to investigate whether stuttering reductions following the instatement phase of a speech-restructuring treatment for adults were accompanied by reductions in the frequency of short intervals of phonation (PIs). The study was prompted by the possibility that reductions in the frequency of short PIs is the mechanism underlying such reductions in stuttering. METHOD: The distribution of PIs was determined for seven adults who stutter, before and immediately after the intensive phase of a speech-restructuring treatment program...

PURPOSE: This study sought to assess whether protective service workers differ from people in non-protective services occupations in their intended reactions towards people who stutter (PWS). METHODS: Analyses were based on questionnaire responses regarding intended reactions toward PWS from 171 protective services workers and 2595 non-protective services workers in the United States. A propensity score matching procedure was used to identify a comparison group of non-protective services workers for the protective services workers...

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 blocks, repetitive, prolongation or cessation of speech. We present a 7.5 -year-old male child with bilateral basal ganglia lesion in globus pallidus with unclear reason...

Despite advances in our understanding of the human speech system, the neurophysiological basis of stuttering remains largely unknown. Here, it is hypothesized that the speech of adults who stutter (AWS) is susceptible to disruptions in sensorimotor integration caused by neural miscommunication within the speech motor system. Human speech unfolds over rapid timescales and relies on a distributed system of brain regions working in a parallel and synchronized manner, and a breakdown in neural communication between the putative brain regions could increase susceptibility to dysfluency...

Cerebral hyperperfusion syndrome (CHS) is a rare complication following cerebral revascularization. It presents with ipsilateral headache, seizures, and intracerebral hemorrhage. It has mostly been described following extracranial carotid endarterectomy and stenting and it is very unusual after intracranial stenting. A 71-year-old man with a stuttering stroke was taken up for a cerebral angiogram (digital subtraction angiography), which showed a dissection of the distal left middle cerebral artery. This was recanalized with a solitaire AB stent...
