Spatial compatibility and anatomical factors in simple and choice reaction time
TLDR
It is concluded that in simple reaction time experiments the difference between ipsilateral and contralateral reactions is due to the elementary anatomical connectivity, and that spatial compatibility becomes important only in choice situations. Expand
Transient Global Amnesia: A Clinical and Sonographic Study
TLDR
TGA patients have fewer vascular risk factors than TIA patients and controls and Cerebral venous hypertension due to incompetence of the internal jugular valve may play a role in the pathogenesis of TGA. Expand
Potential source of cerebral embolism in migraine with aura
TLDR
Patency of the foramen ovale is associated with migraine with aura but not with migraine without aura, and the increased risk of stroke found in epidemiologic studies in patients with migraine with aura may be explained by an increased propensity to paradoxical cerebral embolism. Expand
Transcranial Doppler and risk of recurrence in patients with stroke and patent foramen ovale
TLDR
In patients with PFO‐related stroke, the amount of RLS as assessed with TCD is the only independent predictor of relapse, and in patients with non‐vascular disorders, PFO sizing is mandatory in patientswith PFO. Expand
Transcranial Doppler sonography and magnetic resonance angiography in the assessment of collateral hemispheric flow in patients with carotid artery disease.
TLDR
TCD and MRA should be considered complementary techniques to better understand the changes in intracranial hemodynamics produced by extracranial carotid occlusion and in three cases of middle cerebral artery stenosis TCD was superior to MRA in demonstrating the patency of the vessel. Expand
Transcranial Doppler and transesophageal echocardiography: comparison of both techniques and prospective clinical relevance of transcranial Doppler in patent foramen ovale detection.
TLDR
The results point out the impact of cTCD in the evaluation of RLS volume, thus aiding, in association with the anatomic details by cTEE, in the prevention of the occurrence or recurrence of paradoxical embolism in individuals with and without cerebrovascular diseases. Expand
Patent foramen ovale with paradoxical embolism: mid-term results of transcatheter closure in 256 patients.
TLDR
Transcatheter closure of PFO with or without ASA is a safe and effective, minimally invasive procedure that ensures high closure rate and avoids life-long anticoagulation and mid-term follow-up results appear favorable with respect to recurrent thromboembolic events. Expand
Transcatheter closure of patent foramen ovale: a new migraine treatment?
TLDR
Monitoring the passage of MES in the brain vessels during transcatheter closure of PFO with Amplatzer PFO occluder devices for paradoxical cerebral embolism provided the most accurate assessment of RLS at the brain level. Expand
Vertebrobasilar Ischemia After Neck Motion
TLDR
Evidence is given that the population at risk cannot be identified a priori in the vast majority of cases and symptoms may develop after many uneventful manipulations. Expand
Neuropsychological assessment in patients with relapsing-remitting multiple sclerosis and mild functional impairment: correlation with magnetic resonance imaging.
TLDR
Patients with extensive periventricular demyelination had an inferior performance on concept formation, non-verbal reasoning and verbal memory tests and the neuropsychological results were indicative of a very mild overall impairment. Expand
