BACKGROUND Clopidogrel was superior to aspirin in patients with previous manifestations of atherothrombotic disease in the CAPRIE study and its benefit was amplified in some high-risk subgroups of patients. We aimed to assess whether addition of aspirin to clopidogrel could have a greater benefit than clopidogrel alone in prevention of vascular events with(More)
BACKGROUND AND PURPOSE The efficacy of the antiplatelet agent triflusal for prevention of vascular events after stroke has been reported in a pilot study. However, there is a need to confirm those results in a larger study. METHODS We performed a randomized, double-blind, multicenter study to test the efficacy of triflusal (600 mg/d) versus aspirin (325(More)
BACKGROUND Aspirin is the standard treatment for secondary prevention of stroke and other vascular events. Several studies suggest that triflusal may have a better safety profile. OBJECTIVES To determine in people at high risk of vascular events whether triflusal is an effective and safe treatment for primary and secondary prevention of serious vascular(More)
We identified 14 door-to-door prevalence surveys on dementia, parkinsonism or stroke in Spanish populations fulfilling specific criteria and combined selected age- and sex-specific data using logistic regression and taking Pamplona as a reference. The prevalence of dementia and of Alzheimer's disease varied significantly with space. However, the largest(More)
The logopenic variant of primary progressive aphasia (lvPPA) has been associated with Alzheimer disease, although this relationship is still subject to debate. The purpose of this study is to determine the frequency of amyloid biomarkers in patients with lvPPA, and record any potential clinical or topographic differences between patients with and without(More)
Primary progressive aphasia (PPA) may be the onset of several neurodegenerative diseases. This study evaluates a cohort of patients with PPA to assess their progression to different clinical syndromes, associated factors that modulate this progression, and patterns of cerebral metabolism linked to different clinical evolutionary forms. Thirty-five patients(More)
Thioflavin T derivatives are used in positron-emission tomography (PET) studies to detect amyloid protein deposits in patients with Alzheimer disease. These tracers bind extensively to white matter, which suggests that they may be useful in studies of multiple sclerosis (MS), and that proteins resulting from proteolytic processing of the amyloid precursor(More)
BACKGROUND Myxomas are rare cardiac tumors which often present with stroke caused by tumorous or thrombotic emboli. Treatment with intravenous recombinant tissue plasminogen activator (rtPA) and intra-arterial thrombolysis has been described previously but mechanical thrombectomy has not yet been reported, and treatment of myxoma-related ischemic stroke(More)
