BACKGROUND Motor recovery after stroke is predicted only moderately by clinical variables, implying that there is still a substantial amount of unexplained, biologically meaningful variability in recovery. Regression diagnostics can indicate whether this is associated simply with Gaussian error or instead with multiple subpopulations that vary in their(More)
BACKGROUND Hashimoto encephalopathy has been described as a syndrome of encephalopathy and high serum antithyroid antibody concentrations that is responsive to glucocorticoid therapy, but these could be chance associations. OBJECTIVE To study a patient with Hashimoto encephalopathy and to review the literature to determine whether Hashimoto encephalopathy(More)
Treatments for acute ischaemic stroke continue to evolve. Experimental approaches to restore cerebral perfusion include techniques to augment recanalising therapies, including combination of antiplatelet agents with intravenous thrombolysis, bridging therapy of combining intravenous with intra-arterial thrombolysis, and trials of new thrombolytic agents.(More)
BACKGROUND AND PURPOSE The SSS-TOAST is an evidence-based classification algorithm for acute ischemic stroke designed to determine the most likely etiology in the presence of multiple competing mechanisms. In this article, we present an automated version of the SSS-TOAST, the Causative Classification System (CCS), to facilitate its utility in multicenter(More)
BACKGROUND AND PURPOSE Epidemiological studies of intracerebral hemorrhage (ICH) have consistently demonstrated variation in incidence, location, age at presentation, and outcomes among non-Hispanic white, black, and Hispanic populations. We report here the design and methods for this large, prospective, multi-center case-control study of ICH. METHODS The(More)
OBJECTIVE There is insufficient randomized trial data to support evidence-based recommendations for tight control of fasting blood glucose (FBG) among diabetic subjects in primary stroke prevention. We explored the relationship between FBG among diabetic subjects and risk of ischemic stroke in a multiethnic prospective cohort. RESEARCH DESIGN AND METHODS(More)
BACKGROUND We sought to determine the effect of emergency department length of stay (ED-LOS) on outcomes in stroke patients admitted to the Neurological Intensive Care Unit (NICU). METHODS We collected data on all patients who presented to the ED at a single center from 1st February 2005 to 31st May 2007 with acute ischemic stroke (AIS), intracerebral(More)
OBJECTIVE To characterize short-term prognoses among patients with transient ischemic attack (TIA) and normal diffusion-weighted imaging (DWI) results, TIA patients with abnormal DWI results (transient symptoms associated with infarction [TSI]), and patients with completed ischemic stroke (IS). DESIGN Retrospective study. SETTING University hospital. (More)
OBJECTIVE To determine whether warfarin-treated patients with an international normalized ratio less than 1.7 who receive intravenous tissue plasminogen activator for acute ischemic stroke are at increased risk for symptomatic intracerebral hemorrhage. DESIGN Retrospective study. SETTING Academic hospital. PATIENTS Consecutive patients with acute(More)
Five cases of presumed nicotine withdrawal delirium among brain-injured patients treated in a neurologic intensive care unit are presented. Each patient had a history of heavy tobacco use and experienced dramatic and sustained clinical improvement within hours of transdermal nicotine replacement. These preliminary observations suggest that nicotine(More)
