BACKGROUND AND PURPOSE The etiology of ischemic stroke affects prognosis, outcome, and management. Trials of therapies for patients with acute stroke should include measurements of responses as influenced by subtype of ischemic stroke. A system for categorization of subtypes of ischemic stroke mainly based on etiology has been developed for the Trial of Org(More)
OBJECTIVE To delineate the frequency, course, risk factors, and neuroanatomy of hemispatial neglect in a large stroke cohort. METHODS One thousand two hundred eighty-one patients with acute stroke were enrolled in a multicenter trial of an anticoagulant. Presence and severity of neglect were assessed with the NIH Stroke Scale (NIHSS) neglect item,(More)
OBJECTIVE To compare the baseline National Institutes of Health Stroke Scale (NIHSS) score and the Trial of Org 10172 in Acute Stroke Treatment (TOAST) stroke subtype as predictors of outcomes at 7 days and 3 months after ischemic stroke. METHODS Using data collected from 1,281 patients enrolled in a clinical trial, subtype of stroke was categorized using(More)
BACKGROUND AND PURPOSE Information about the long-term prognosis of young adults with ischemic stroke is limited. Therefore, we performed a follow-up assessment of 296 patients with ischemic stroke who are enrolled in the Iowa Registry of Stroke in Young Adults. We studied young adults (age, 15 to 45 years) who were referred to a tertiary medical center for(More)
The International Cooperative Study on the Timing of Aneurysm Surgery evaluated the results of surgical and medical management in 3521 patients between December, 1980, and July, 1983. At admission, 75% of patients were in good neurological condition and surgery was performed in 83%. At the 6-month evaluation, 26% of the patients had died and 58% exhibited a(More)
A prospective, observational clinical trial was conducted by the International Cooperative Study on the Timing of Aneurysm Surgery to determine the best time in relation to the hemorrhage for surgical treatment of ruptured intracranial aneurysms. Sixty-eight centers contributed 3521 patients in a 2 1/2-year period beginning in December, 1980. Analysis by a(More)
OBJECTIVES To describe the likely causes of ischemic stroke in a population of young adults and to report the influence of strict algorithms on the diagnosis of the likely cause of stroke in this cohort. DESIGN Between July 1, 1977, and January 1, 1993, we registered 329 young adults with ischemic stroke in our registry. Diagnostic studies were selected(More)
Cerebral ischemia from vasospasm is a major cause of death and disability following aneurysmal subarachnoid hemorrhage (SAH). This study examines and compares the relative utility of the initial neurologic examination and early CT in predicting cerebral ischemia after SAH. The influence of antifibrinolytic drugs (AFD) in the development of cerebral ischemia(More)
To test interphysician agreement on the diagnosis of subtype of ischemic stroke, we sent subtype definitions and 18 case summaries (clinical features and pertinent laboratory data) to 24 neurologists who have a special interest in stroke, and asked them to determine the most likely subtype diagnosis. The overall agreement was 0.64 (Kappa [K] = 0.54).(More)
