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 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)
BACKGROUND Intracranial artery stenosis is assumed to represent atherosclerotic plaque. Catheter cerebral arteriography shows that intracranial stenosis may progress, regress, or remain unchanged. It is counterintuitive that atherosclerotic plaque should spontaneously regress, raising questions about the composition of intracranial stenoses. Little is known(More)
OBJECTIVE We report the case of a patient with a dural arteriovenous fistula whose neurobehavioral syndrome was indistinguishable from that of an ischemic stroke. BACKGROUND Case studies of dural arteriovenous fistulas primarily describe global cognitive changes like dementia, but detailed neurocognitive evaluations of dural arteriovenous fistula patients(More)
