Intravenous thrombolysis with recombinant tissue plasminogen activator for acute hemispheric stroke. The European Cooperative Acute Stroke Study (ECASS)
Intravenous thrombolysis in acute ischemic stroke is effective in improving some functional measures and neurologic outcome in a defined subgroup of stroke patients with moderate to severe neurologic deficit and without extended infarct signs on the initial CT scan, however, the identification of this subgroup is difficult.
Randomised double-blind placebo-controlled trial of thrombolytic therapy with intravenous alteplase in acute ischaemic stroke (ECASS II). Second European-Australasian Acute Stroke Study Investigators.
Despite the increased risk of intracranial haemorrhage, thrombolysis with alteplase at a dose of 0.9 mg/kg in selected patients may lead to a clinically relevant improvement in outcome.
Morphological and Functional Characteristics of Patent Foramen Ovale and Their Embolic Implications
The association of right-to-left shunting at rest and high membrane mobility, as detected by contrast TEE, seems to identify PFO patients with cerebrovascular ischemic events who are at higher risk for recurrent brain embolism.
Collaborative overview of randomised trials of antiplatelet therapy Prevention of death, myocardial infarction, and stroke by prolonged antiplatelet therapy in various categories of patients
There was no appreciable evidence that either a higher aspirin dose or any other antiplatelet regimen was more effective than medium dose aspirin in preventing vascular events, so in each of the four main high risk categories overall mortality was significantly reduced.
Comparison of cerebral angiography and transcranial Doppler sonography in acute stroke.
Higher flow velocities in the anterior cerebral artery or posterior cerebral artery, mostly in the symptomatic hemisphere, often accompanied middle cerebral artery pathology, probably indicating collateral compensatory pathways.
Functional Basis of Memory Impairment in Multiple Sclerosis: A [18F]FDG PET Study
The findings indicate that hypometabolism of thalamic and deep cortical gray structures of the temporal lobe is associated with episodic memory dysfunction in MS and pathological performance on tests designed to assess frontal functions was associated with widespread reduction of glucose metabolism.
Sleep patterns in acute ischemic stroke
Evidence is provided that polysomnographic recording is useful to detect symptoms of patients with different clinical outcomes during the acute phase of ischemic stroke, as well as the severity of neurological deficit at outcome.
