BACKGROUND Neuromyelitis optica (NMO) is a severe inflammatory demyelinating disease of the CNS in which a pathogenic role of anti-aquaporin-4 (AQP4) antibodies has been suggested. Although AQP4 is expressed in human cortex, recent histologic studies have failed to find any evidence of cortical demyelination in NMO. OBJECTIVE To evaluate, in vivo, the(More)
BACKGROUND AND PURPOSE Complications after stroke increase disability or death. The disability-adjusted life-year (DALY) metric, developed by the World Health Organization to measure the global burden of disease, integrates both mortality and disability. Widely used in population-level data analyses, it has not been applied to individual patient-level data(More)
The aim of the Part I of Stroke Statistics in Korea is to summarize nationally representative data of the epidemiology and risk factors of stroke in a single document. Every year, approximately 105,000 people experience a new or recurrent stroke and more than 26,000 die of stroke, which indicates that every 5 minutes stroke attacks someone and every 20(More)
BACKGROUND AND PURPOSE Health-related quality of life (HRQoL) is a multidimensional concept that signifies a subjective evaluation of perceived health; hence, it has gained wide acceptance in geriatrics. However, its application has not been tested in patients with post-stroke cognitive impairment with no dementia (PSCIND). We investigated whether PSCIND(More)
OBJECTIVE To evaluate the impact of neurological and medical complications on 3-month outcomes in acute ischaemic stroke patients. METHODS We prospectively investigated complications for all the consecutive acute ischaemic stroke patients admitted within 7 days from onset in four university hospitals during a 1-year period. Baseline data and 3-month(More)
BACKGROUND This study aimed to investigate the long-term mortality and recurrence rate of stroke in first-time stroke patients with symptomatic isolated middle cerebral artery disease (MCAD) under medical management. METHODS We identified 141 first ever stroke patients (mean age, 64.4 ± 12.5 years; 53% male) with symptomatic isolated MCAD. MCAD was(More)
BACKGROUND Delayed arrival at hospital is one of the major obstacles in enhancing the rate of thrombolysis therapy in patients with acute ischemic stroke. Our study aimed to investigate factors associated with prehospital delay after acute ischemic stroke in Korea. METHODS A prospective, multicenter study was conducted at 14 tertiary hospitals in Korea(More)
BACKGROUND AND PURPOSE An optimal strategy for management of symptomatic intracranial atherosclerotic stenosis (ICAS) has not yet been established. We compared the efficacy of 2 combinations of antiplatelets, aspirin plus cilostazol (cilostazol group) verus aspirin plus clopidogrel (clopidogrel group), on the progression of ICAS, which is known to be(More)
The aim of the current Part II of Stroke Statistics in Korea is to summarize nationally representative data on public awareness, pre-hospital delay, thrombolysis, and quality of acute stroke care in a single document. The public's knowledge of stroke definition, risk factors, warning signs, and act on stroke generally remains low. According to studies using(More)
Characteristics of stroke cases, acute stroke care, and outcomes after stroke differ according to geographical and cultural background. To provide epidemiological and clinical data on stroke care in South Korea, we analyzed a prospective multicenter clinical stroke registry, the Clinical Research Center for Stroke-Fifth Division (CRCS-5). Patients were 58%(More)
