OBJECTIVE To determine whether the ratio single chain (sc)/(sc + 2 chain [tc]) recombinant tissue plasminogen activator (rtPA) influences outcomes in patients with cerebral ischemia. METHODS We prospectively included consecutive patients treated with IV rtPA for cerebral ischemia in 13 stroke centers and determined the sc/(sc + tc) ratio in the treatment(More)
BACKGROUND The provision of informed consent is a prerequisite for inclusion of a patient in a clinical research project. In some countries, the legislation on clinical research authorizes a third person to provide informed consent if the patient is unable to do so directly (i.e. surrogate consent). This is the case during acute stroke, when the symptoms(More)
INTRODUCTION The Stroke and Cognition consortium (STROKOG) aims to facilitate a better understanding of the determinants of vascular contributions to cognitive disorders and help improve the diagnosis and treatment of vascular cognitive disorders (VCD). METHODS Longitudinal studies with ≥75 participants who had suffered or were at risk of stroke or TIA(More)
Stroke patients have an elevated risk of developing long-term cognitive disorders or dementia. The latter is often associated with atrophy of the medial temporal lobe. However, it is not clear whether hippocampal and entorhinal cortex atrophy is the sole predictor of long-term post-stroke dementia. We hypothesized that hippocampal deformation (rather than(More)
Many stroke patients have pre-existing cognitive impairment. Plasma amyloid β peptides (Aβ) - possible biomarkers of Alzheimer's pathology - induce vascular dysfunction. Our objective was to evaluate factors influencing plasma Aβ1-40 and Aβ1-42 peptides in a cohort of stroke patients. In the Biostroke study (ClinicalTrials.gov Identifier: NCT00763217), we(More)
