Prognosis of Asymptomatic Intracranial Stenosis in Patients With Transient Ischemic Attack and Minor Stroke
This cohort study examines the age-specific prevalence and prognosis of asymptomatic intracranial stenosis in British patients with transient ischemic attack and minor stroke.

Asymptomatic Intracranial Artery Stenosis —One Less Thing to Worry About
Intracranial artery stenosis (ICAS) is a leading cause of stroke worldwide. It is estimated to account for 10% of ischemic strokes in the US and perhaps up to 50% of strokes in Asia. Despite its frequency and role in stroke-related morbidity and mortality, ICAS has received less attention compared with extracranial atherosclerotic disease. In the past 15 years, clinical trials have refined the treatment approach for patients with recent stroke or transient ischemic attack (TIA) and ICAS. However, less information is available pertaining to asymptomatic ICAS.

Care Delivery and Outcomes for Acute Stroke and Transient Ischemic Attacks in Rural and Urban Medicare Patients
This cohort study describes trends among rural and urban patients with acute ischemic stroke or transient ischemic attack in the type of health care centers to which patients were admitted, what care was provided, and patient outcomes.

Importance of the Intention-to-Treat Principle
To the Editor The recent study by Goyal et al represents the third largest cohort study on patients with large vessel occlusions (LVOs) who present with mild deficits (National Institutes of Health Stroke Scale score, 0-5) and, to our knowledge, the largest meta-analysis regarding this topic. This highlights the growing interest on how to optimally treat such patients.

Magnetic Resonance Imaging for Acute Minor Neurological Symptoms
To the Editor An observational study of magnetic resonance imaging (MRI) in acute minor neurological symptoms revealed imaging evidence for acute infarction in 13.5% and revision of clinical diagnosis in 30%. This “implies a considerable percentage of patients’ negative MRI findings resulted in a different diagnosis, likely that a presumed stroke did not exist.” This conclusion is misleading in 2 respects.

Nomenclature and Potential Causation Classification of Patent Foramen Ovale –Associated Stroke
This Special Communication describes new information on strokes associated with patent foramen ovale from randomized clinical trials and meta-analyses and proposes a new clinical approach to the categorization of such strokes.

Enhanced Paramedic Acute Stroke Treatment Assessment and Thrombolysis Delivery in Emergency Stroke Care
This cluster randomized clinical trial sought to examine whether adding enhanced paramedic assessment to standard care would result in increased rates of thrombolysis in patients experiencing stroke.

Implementation of a Prehospital Stroke Triage System Using Symptom Severity and Teleconsultation
This cohort study examines a system for prehospital triage for Swedish patients with suspected acute stroke.

Triage Based on Preclinical Scores
Current guidelines state that patients who experienced a stroke should usually be transferred to the nearest stroke-treating hospital. In accordance with these guidelines, most patients with large-vessel occlusion (LVO) are transported to a primary stroke center (PSC) that does not offer thrombectomy. From there, these patients must undergo a secondary interhospital transport to a thrombectomy-capable comprehensive stroke center (CSC). Such secondary transfers cause considerable treatment delays, ranging from 96 to 111 minutes. Even when the distance between the PSC and a CSC is only 15 miles, transfer times of 104 minutes have been reported.

Effect of Remote Ischemic Perconditioning on Brain Infarct Growth in Patients With Ischemic Stroke
This randomized clinical trial examines whether in-hospital treatment with remote ischemic perconditioning that is administered within 6 hours of symptom onset, with or without reperfusion therapy, can reduce brain infarction volume growth in patients with acute ischemic stroke.

Endovascular Treatment for Acute Basilar Artery Occlusion via a Nationwide Prospective Registry
This nonrandomized cohort study evaluates the association between endovascular treatment and the clinical outcomes of patients with stroke and acute basilar artery occlusion, compared with patients who received standard medical treatment only.
