This study examines whether etiologic stroke subtyping using 3 different classification systems identifies different disease processes that can be recognized through their different clinical courses.

Association of Collateral Blood Vessels With Neurological Outcome After Stroke
This cohort study assesses the association between the presence of collateral vessels identified using arterial spin labeling magnetic resonance imaging and neurologic outcome in patients after acute ischemic stroke.

Hypertension —A Global Neurological Problem
This Viewpoint discusses the gap in hypertension and stroke care between low-income countries and high-income countries and the role neurologists should play in stroke-prevention efforts.

Improved Outcomes in Asymptomatic Obstructive Sleep Apnea
This study enrolled 1522 randomly selected, employed research subjects and observed them for 2 decades. The goal of WSCS was to answer one aspect of a US Congressional mandate to determine the overall public burden of sleep d isorders. The WSCS had a surprising finding: mild OSA was seen in 17% of adults, and, most concerning, 6% of adults had moderate to severe OSA. The WSCS finding most relevant to the current USPSTF recommendation statement is that only 35% of WSCS participants with moderate OSA and 37% of participant s with severe OSA reported excessive daytime sleepiness, the cardinal daytime symptom of OSA. This sugg...

Stroke Diagnosis and Treatment in the Emergency Department
To the Editor We are somewhat perplexed after having read the Viewpoint by Avasarala, as it questions the role of the neurologist in the emergency department for acute stroke diagnosis. Although it is clear that the author is being deliberately provocative, we can only strongly disagree with the idea that a sudden-onset focal neurological deficit may be diagnosed as a stroke on the basis of a pattern-recognition algorithm alone, without a neurological assessment.

Stroke Diagnosis and Treatment in the Emergency Department —Reply
In Reply I thank Rota and colleagues for their comments on my Viewpoint, which challenged the status quo concerning the requirement of a neurologist to initiate the tissue plasminogen activator (tPA) protocol for an obvious diagnosis of acute stroke in the emergency department (ED). In today ’s world of Instagram, Facebook, and Twitter feeds, we all need to embrace change. A few years ago, for instance, no one knew what Altmetric represented. Today, all of us crave the statistics reported by Altmetric, which recognizes our work via the number of tweets and “cross-talk” across mult iple platforms. Funding, data collec...

Recurrence of Posterior Circulation Childhood Arterial Ischemic Stroke
This cohort study investigates the incidence of the recurrence of childhood arterial ischemic stroke in the posterior and anterior circulations to determine if the risk differs between the 2 locations.

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...

Thrombolysis and Thrombectomy vs Thrombectomy Alone for Ischemic Stroke
This study examines whether treatment with intravenous thrombolysis before mechanical thrombectomy with a stent retriever is beneficial in patients undergoing mechanical thrombectomy.

SSRIs and Intracranial Hemorrhage
Selective serotonin reuptake inhibitors (SSRIs) are among the most commonly prescribed medications in the United States. A recent study using the National Health and Nutrition Examination Survey database estimated that in 2012, 8.5% (95% CI, 6.9%-10.4%) of adults 20 years and older were prescribed SSRIs compared with a prevalence of 1.3% (95% CI, 1.0%-1.8%) for tricyclic antidepressants (TCAs). Although most of these prescriptions were likely for depression, SSRIs are being used for other indications; of particular interest to neurologists, SSRIs are being investigated and sometimes used to promote motor recovery after str...

Intra-arterial Treatment for Basilar Artery Occlusion —Reply
In Reply We thank Bhatti and Sivakumaran for their comments on our article. First, the authors mention the relatively low mean age of 58 years of our cohort (this includes 1 child of 4 years). The patients in the Basilar Artery International Cooperation Study (BASICS) had a mean age of 63 years. We think it is unlikely that this difference of 5 years has had an important influence on the results. Moreover, BASICS is a prospective patient registry, without stringent inclusion criteria. This suggests that patients with basilar artery occlusion have a lower age compared with patients with anterior circulation stroke.

Cardiovascular Risk Factors and Stroke in Alzheimer Disease
To the Editor I read with interest the article by Tosto et al studying the influence of cardiovascular risk factors and stroke in familial late-onset Alzheimer disease (LOAD). The main findings were that history of stroke increased the risk for LOAD, while hypertension decreased the risk for LOAD. The study suggests that stroke mediates the influence of cardiovascular risk factors on increased risk for LOAD.
