“Accent issue”: foreign accent syndrome following ischemic stroke
In conclusion, FAS is a rare motor speech disorder, often related to cerebrovascular accidents involving critical regions in the dominant hemisphere. In addition, the present case adds further evidence to the role of the left primary motor cortex in modulation of prosody. In rare cases FAS can be the only sign of stroke or can appear after recovery from post-stroke aphasia.

Generalizing post-stroke prognoses from research data to clinical data
Publication date: Available online 14 October 2019Source: NeuroImage: ClinicalAuthor(s): Robert Loughnan, Diego L. Lorca-Puls, Andrea Gajardo-Vidal, Valeria Espejo-Videla, Céline R. Gillebert, Dante Mantini, Cathy J. Price, Thomas M.H. HopeAbstractAround a third of stroke survivors suffer from acquired language disorders (aphasia), but current medicine cannot predict whether or when they might recover. Prognostic research in this area increasingly draws on datasets associating structural brain imaging data with outcome scores for ever-larger samples of stroke patients. The aim is to learn brain-behavior trends from these ...

Understanding Aphasia: Realities and Strategies for EMS Providers
Photo provided by Avi Golden Avi Golden is an EMT who can no longer talk after suffering a stroke. He now makes it his mission to educate others about those dealing with aphasia.   Editor’s Introduction It was a chance encounter one day as I scanned Facebook posts from “friends” and acquaintances. I have countless “friends”, many of which I have never met in person, but find, through their content or other “friends” to be in my world of interest and specialization. Several postings were from paramedic Avi Golden, one such “friend” I followed frequently on Facebook and found to be sharp, inquisitive a...

Predictive role of subcomponents of the left arcuate fasciculus in prognosis of aphasia after stroke: A retrospective observational study
The relationship between the left arcuate fasciculus (AF) and stroke-related aphasia is unclear. In this retrospective study, we aimed to investigate the role of subcomponents of the left AF in predicting prognosis of aphasia after stroke. Twenty stroke patients with aphasia were recruited and received language assessment as well as diffusion tensor tractography scanning at admission. According to injury of the left AF, the participants were classified into four groups: group A (4 cases), the AF preserved intactly; group B (6 cases), the anterior segment injured; group C (4 cases), the posterior segment injured; and group ...

The utility of lesion classification in predicting language and treatment outcomes in chronic stroke-induced aphasia
This study aimed to evaluate the utility of lesion classification via gray matter (GM)-only versus combined GM plus white matter (WM) metrics and to determine structural measures associated with aphasia severity, naming skills, and treatment outcomes. Thirty-four patients with chronic aphasia due to left hemisphere infarct completed T1-weighted and DTI scans and language assessments prior to receiving a 12-week naming treatment. GM metrics included the amount of spared tissue within five cortical masks. WM integrity was indexed by spared tissue and fractional anisotropy (FA) from four homologous left and right association ...

Robot-Assisted Therapy in Upper Extremity Hemiparesis: Overview of an Evidence-Based Approach
Conclusion Robotic therapy has matured and represents an embodiment of a paradigm shift in neurorehabilitation following a stroke: instead of focusing on compensation, it affords focus in ameliorating the impaired limb in line with concepts of neuroplasticity. This technology-based treatment provides intensity, interactivity, flexibility, and adaptiveness to patient's performance and needs. Furthermore, it increases the productivity of rehabilitation care. Of course, efficiency must be discussed within a local perspective. For example, following the cost containment shown in the VA ROBOTICS study (46), the UK Nati...

Anxiety in Patients With Acute Ischemic Stroke: Risk Factors and Effects on Functional Status
Conclusion: Depressive symptoms are the major correlates of PSA while more severe PSA is associated with poorer ADL and health-related QOL. Acute lesions involving CHWM may correlate with PSA in ischemic stroke patients with mild-to-moderate neurologic deficits, supporting a lesion-location hypothesis in PSA.IntroductionAnxiety is prevalent after stroke and occurs in about one-quarter of stroke survivors (1, 2). Poststroke anxiety (PSA) may have a negative impact on quality of life (QOL) of stroke survivors, affecting their rehabilitation (3). Furthermore, one prospective study found that severe anxiety symptoms were assoc...

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Repetitive verbal behaviors are not always harmful signs: Compensatory plasticity within the language network in aphasia.
Abstract Repetitive verbal behaviors such as conduite d'approche (CdA) and mitigated echolalia (ME) are well-known phenomena since early descriptions of aphasia. Nevertheless, there is no substantial fresh knowledge on their clinical features, neural correlates and treatment interventions. In the present study we take advantage of three index cases of chronic fluent aphasia showing CdA, ME or both symptoms to dissect their clinical and neural signatures. Using multimodal neuroimaging (structural magnetic resonance imaging and [18]-fluorodeoxyglucose positron emission tomography during resting state), we found that...

A Case of Lenticulostriate Stroke Due to Minor Closed Head Injury in a 2-Year-Old Child: Role of Mineralizing Angiopathy
Conclusions Some infants can present with the onset of stroke-like symptoms after minor head injuries. Presence of linear calcifications of the basal ganglia noticed on brain computed tomography in many of these patients suggests that mineralizing angiopathy may be a predisposing factor for lenticulostriate stroke after minor closed head injury in infants. Brain magnetic resonance imaging to further delineate possible cerebral infarction is indicated.

Description of stroke mimics after complete neurovascular assessment
ConclusionsIn our sample, 8.8% of all diagnoses of ischaemic stroke were SM. These events have different demographic, clinical, and prognostic characteristics; epilepsy is the most common aetiology. Despite receiving specialised emergency care, 19 patients with SM (4.7%) were treated with intravenous fibrinolysis.ResumenIntroducciónUn porcentaje de casos diagnosticados inicialmente como infartos isquémicos son de causa no cerebrovascular o stroke mimics (SM). Los datos publicados al respecto son heterogéneos y, generalmente, con cohortes pequeñas.ObjetivoNuestro objetivo es establecer qué enfermedades cursan como SM, ...

Delayed Endovascular Thrombectomy in a Patient Suffering from Stroke in Progression after Intravenous Thrombolytic Therapy.
CONCLUSION: In LAO patients, directly proceeding EVT following IVT may not be hesitated. In addition, while LAO patients with incomplete IV-tPA treatment responses result in transient improvement of neurological symptoms but later reversed, EVT may be a potential rescue therapy in carefully selected patients.
