Optimizing Prehospital Triage for Patients With Stroke Involving Large Vessel Occlusion
The past 20 years have witnessed a revolution in the paradigm of acute ischemic stroke treatment. In 1996, intravenous alteplase was shown to improve outcomes among patients treated within 3 hours of stroke onset. This finding upended the historical therapeutic nihilism about stroke, and with it the leisurely armchair approach to stroke treatment. The concept of so-called acute ischemic stroke emerged. This changed the nature and practice of vascular neurology, created a vigorous and sometimes controversial debate between vascular neurologists and emergency physicians about the merits of alteplase, and paved the way for mo...

Effect of Dextroamphetamine on Poststroke Motor Recovery
This randomized clinical trial evaluates the effect of dextroamphetamine combined with physiotherapy vs placebo and physiotherapy for improving poststroke motor recovery among patients with ischemic stroke.

Treatment of Poststroke Aphasia With Transcranial Direct Current Stimulation
Stroke remains a leading cause of human disability. Important gains have been realized in the setting of acute ischemic stroke, where thrombolytic and catheter-based reperfusion therapies can substantially improve long-term behavioral outcomes. However, most patients with a new stroke are not eligible for such therapies because of delays in diagnosis or hemorrhagic etiology, for example, and many who are treated nonetheless have substantial long-term disability. Additional classes of poststroke therapy are needed.

Prehospital and Early Postarrival Neurological Deterioration in Acute Stroke
This exploratory analysis of 1690 patients enrolled in the Field Administration of Stroke Therapy-Magnesium Trial assesses the frequency, predictors, and outcomes of the neurological deterioration that occurs among patients during the ultra-early period after ischemic stroke or intracranial hemorrhage.

Additional Factors Regarding Clinical Outcomes of General Anesthesia and Conscious Sedation for Acute Ischemic Stroke
To the Editor Simonsen et al concluded that general anesthesia (GA) did not influence infarct growth compared with conscious sedation in endovascular-treated patients with acute stroke. This is an interesting study that addresses topical questions. However, we would like to point out some limitations.

Additional Factors Regarding Clinical Outcomes of General Anesthesia and Conscious Sedation for Acute Ischemic Stroke —Reply
In Reply We thank Chabanne and Futier for the relevant question concerning ventilator parameters in the General or Local Anesthesia in Intra Arterial Therapy (GOLIATH) trial. Unfortunately, it was not possible for us to obtain periprocedural arterial blood gas parameters because of resource constraints. However, we have recently reported the end tidal carbon dioxide (EtCO2) levels in the general anesthesia (GA) arm (4.4 kPa; interquartile range, 4.2-4.8 kPa). Taking the normal arterial to EtCO2 gradient into account, our data indicate a normoventilation, which was the intention in the study protocol. The EtCO2 levels were ...

Presentation After TIA and Minor Stroke in Relation to the UK FAST Public Education Campaign

Error in Table
The Research Letter titled, “Medical Specialties of Clinicians Providing Mechanical Thrombectomy to Patients with Acute Ischemic Stroke in the United States,” published in the April 2018 print issue included an error in the Table that presented the data for neurosurgeons in the row labeled “Neurology,” and the data for neurologists in the row labeled “Neurosurgery.” This included indicating that 110 thrombectomies were performed by neurosurgeons and 91 by neurologists. The Table has been corrected and now matches the data present in the main text of the article: 91 thrombectomies performed by neurosurgeons an d...

Additional Factors in Considering Patent Foramen Ovale Closure to Prevent Recurrent Ischemic Stroke
To the Editor In his Viewpoint, Kamel addresses some issues with the randomized clinical trials (RCTs) of patent foramen ovale (PFO) closure for preventing recurrent stroke and urges a judicious and evidence-based approach for patient selection. I would like to point out additional factors that further demonstrate need for extreme caution in selecting patients to undergo this procedure.

Additional Factors in Considering Patent Foramen Ovale Closure to Prevent Recurrent Ischemic Stroke —Reply
In Reply Powers raises several important issues that I did not address in detail in my Viewpoint about managing patent foramen ovale in patients with ischemic stroke. These additional points further highlight that many patients who are fully informed about the available data will reasonably choose medical therapy rather than patent foramen ovale closure.

Considerations in Assessing Disability Trajectories
To the Editor We thank Dhamoon et al for their prospective longitudinal cohort study assessing the long-term disability trajectory before and after an ischemic stroke compared with myocardial infarction (MI). The authors found that the gradient of increasing disability was significantly steeper after a stroke but remained consistent after MI.
