Precision Medicine for Ischemic Stroke
This Viewpoint discusses the future of precision medicine in the field of ischemic stroke, first looking at the current status of genetic approaches and then exploring the status of phenotype-based delineations.

Blood Pressure, Blood Glucose, and Temperature After Childhood Stroke
This cohort study aims to determine the prevalence of abnormal blood pressure, blood glucose levels, and temperature in pediatric patients with acute arterial ischemic stroke and to explore any association between these measures and neurological outcome.

Computed Tomography Perfusion and Diffusion-Weighted Imaging in Acute Stroke
To the Editor In JAMA Neurology, Rudilosso and colleagues presented 2 cases using computed tomography perfusion (CTP) and diffusion-weighted imaging (DWI). They suggested that CTP was superior to DWI in the identification of ischemic changes in acute stroke. In most patients, DWI findings appear positive within several minutes to several hours of the onset of acute cerebral infarction. Positive DWI findings depend on cytotoxic edema. The morphology of the brain maintains intact when cerebral blood flow is decreased to 30% of its normal level. If perfusion is returned to normal, no abnormality will be detected by DWI. When ...

Instrument for Predicting Early Stroke Recurrence
To the Editor The Recurrence Risk Estimator has been put forward as a web-based prognostic score that integrates clinical and imaging information available in the acute setting to quantify early risk for recurrence of stroke. The validity of a prognostic score was examined in a multicenter study by Arsava et al, which aptly assessed the external validity and transferability of the Recurrence Risk Estimator. We would like to put forward the following fallacies we noted in this study.

Stent Retrievers for Treating Anterior Circulation Acute Ischemic Stroke
To the Editor Touma et al reported a comprehensive systematic review and meta-analysis of 5 randomized clinical trials evaluating the benefits and risks of stent retrievers in addition to recombinant tissue plasminogen activator (rtPA) for the treatment of acute ischemic stroke (AIS). The main conclusion of the study was that “the use of stent retrievers in conjunction with rtPA vs rtPA alone is associated with significant improvement of functional independence 90 days after AIS.” However, as pointed out by the authors, all studies included in their meta-analysis selected only patients with anterior circulation acute i...

Factors Associated With Neurological Outcome After Childhood Stroke
To the Editor We thank Grelli et al for their study investigating the factors associated with neurological outcome following childhood stroke. The authors reported an association between hyperglycemia and poor neurological outcome in their cohort.

Neurologists and the Diagnosis of Acute Stroke in the ED
This Viewpoint proposes that acute stroke can be managed in the emergency department without the expertise of a neurologist.

Endovascular Therapy for Acute Ischemic Stroke
This pooled cohort study evaluates the safety and effectiveness of endovascular therapy for occlusions of the M2 segment of the middle cerebral artery in patients with ischemic stroke.

Risk of Pregnancy-Associated Stroke Across Age Groups
This population-based cohort study uses data from the New York State SPARCS database to examine the risk of stroke in women of childbearing age who are pregnant or post partum compared with the risk in those who are not pregnant.

Endovascular Treatment for Patients With Stroke and Large Ischemic Cores and Mismatch Imaging Profiles
This case-control study compares the outcomes of patients following stroke with large baseline ischemic cores on computed tomographic perfusion undergoing endovascular therapy with the outcomes of matched controls who had medical care alone.

Mechanical Thrombectomy for Acute Ischemic Stroke
Coutinho et al have performed a timely post hoc analysis consisting of a patient population from 2 large, prospective, core laboratory –adjudicated trials: Solitaire With the Intention for Thrombectomy (SWIFT) and Solitaire Flow Restoration Thrombectomy for Acute Revascularization (STAR), and their report appears in this issue ofJAMA Neurology. Given that 85% of the patients in mechanical thrombectomy (MT) trials received intravenous thrombolysis (IVT), they highlight an important group of patients in whom MT was successful without IVT. The recent IVT and MT trials have clearly established the new standard in therapy for...
