BACKGROUND Results of trials of aspirin and dipyridamole combined versus aspirin alone for the secondary prevention of vascular events after ischaemic stroke of presumed arterial origin are inconsistent. Our aim was to resolve this uncertainty. METHODS We did a randomised controlled trial in which we assigned patients to aspirin (30-325 mg daily) with(More)
OBJECTIVE To investigate the prevalence of asymptomatic intracranial stenosis using transcranial Doppler ultrasonography in patients with evidence of asymptomatic carotid stenosis. BACKGROUND Symptomatic atherosclerotic intracranial largeartery stenosis accounts for approximately 10% of ischemic strokes annually. It is unknown whether a significant risk(More)
Currently, intracerebral hemorrhage (ICH) has the highest mortality rate of all stroke subtypes (Counsell et al 1995; Qureshi et al 2005). Hematoma growth is a principal cause of early neurological deterioration. Prospective and retrospective studies indicate that up to 38% hematoma expansion is noted within three hours of ICH onset and that hematoma volume(More)
When a patient with migraine has a stroke, all other causes of stroke should be ruled out before the stroke is attributed to migraine. Migraine mimics that present with headaches and stroke, including arteriovenous malformation and cervical carotid artery dissection, should be considered. Patent foramen ovale is a risk factor for both migraine and stroke(More)
Lyme disease, a multisystem illness caused by the spirochete Borrelia burgdorferi, is the most common vector-borne disease in the United States. There are 3 clinical stages of Lyme disease: early localized, early disseminated, and late persistent disease. Neuroborreliosis, infection of the nervous system by B. burgdorferi, may occur during early(More)
Atherosclerotic plaque at the arch of the aorta has been identified as a potential source for atheroembolic stroke. Imaging of aortic arch plaque can be performed with transesophageal echocardiography (TEE), but TEE is an invasive procedure. A new noninvasive method has been developed to image aortic arch plaque employing transcutaneous real time B-mode(More)
