PURPOSE To evaluate the feasibility and safety of stent implantation to treat ostial vertebral artery stenosis. METHOD Fifty-eight symptomatic patients (44 men; mean age 72 years, range 54 to 88) with 67 ostial vertebral artery lesions received 67 balloon-expandable coronary stents. Follow-up angiography was performed if restenosis was suspected or during(More)
PURPOSE Earlier and more intense rehabilitation benefit stroke patients. Yet, studies have caution intensive therapy during acute brain injury. This study examined the rehabilitation commencement time and intensity as predictors of functional outcomes in acute stroke patients admitted to the stroke intensive care unit (ICU). METHOD Sociodemographic,(More)
Recently, transcranial color-coded sonography (TCCS) has been found to have a diagnostic value in patients with idiopathic Parkinson's disease (IPD), which displays increased hyperechogenicity at the substantia nigra (SN). To use TCCS, to assess the difference in SN hyperechogenicity and intracranial hemodynamics among subjects with IPD, vascular(More)
BACKGROUND Long-term exposure to ingested arsenic has been documented to induce peripheral vascular disease, ischemic heart disease, and cerebral infarction in a dose-response relationship. This study further examined the biological gradient between ingested inorganic arsenic and carotid atherosclerosis. METHODS AND RESULTS We studied 199 male and 264(More)
OBJECTIVES This study sought to report technical details and clinical results of the first series of endovascular recanalization for cervical internal carotid artery (ICA) occlusion. BACKGROUND Cervical ICA occlusion is associated with impaired cerebral perfusion, which may lead to ischemic cerebral symptoms and hemodynamic infarcts. Neither surgical nor(More)
BACKGROUND/PURPOSE Behavioral and psychologic symptoms of dementia (BPSD) are major sources of a caregiver's burden and also the most important factor when considering the need for institutionalization of dementia patients. BPSD occur in about 90% of patients with dementia. Studies comparing the BPSD in the major types of dementia using unitary behavioral(More)
BACKGROUND AND PURPOSE Atherosclerosis is the main cause of common carotid artery occlusion in most reports. This study aimed to identify the major causes of common carotid artery occlusion and compare the clinical features and carotid duplex ultrasonography findings of patients with common carotid artery occlusion attributable to each cause. METHODS(More)
Pregnancy may increase the risk of stroke. However, few studies have compared strokes in women of reproductive age that occur in pregnancy or the puerperium (pregnancy-related stroke, PRS) with those unrelated to pregnancy. This study assesses risk factors and etiologies of stroke in these women based on relationship to pregnancy. From 1984 to 2002, all(More)
OBJECTIVE To identify the midlife risk factors for subtypes of dementia newly developed later in life. METHODS A nested case-control study was conducted on 157 demented cases and 628 comparison cases selected from 40,636 men and women who were enrolled from 1982 to 1992. Four comparison cases were frequency-matched on age, time at enrollment (within 6(More)
Mutations in the TBK1 gene were just recently identified to cause amyotrophic lateral sclerosis (ALS), and their role in ALS in various populations remains unclear. The aim of this study was to determine the frequency and spectrum of mutations in TBK1 in a Taiwanese ALS cohort of Han Chinese origin. Mutational analyses of TBK1 were carried out by direct(More)
