The etiology of posterior circulation infarcts
In a prospective study of 70 patients with infarcts in the posterior circulation admitted consecutively to a population-based primary-care center, we assessed infarct location and etiology usingExpand
Thalamic vascular lesions. Risk factors and clinical course for infarcts and hemorrhages.
BACKGROUND AND PURPOSE The data of patients with an MRI-confirmed diagnosis of thalamic stroke were analyzed to identify risk factors and to describe the clinical syndromes according to the thalamicExpand
Effect of a Novel Free Radical Scavenger, Edaravone (MCI-186), on Acute Brain Infarction
Edaravone, a novel free radical scavenger, demonstrates neuroprotective effects by inhibiting vascular endothelial cell injury and ameliorating neuronal damage in ischemic brain models. The presentExpand
Disappointing reliability of pulsatility indices to identify candidates for magnetic resonance imaging screening in population-based studies assessing prevalence of cerebral small vessel disease
Background: Diagnosis of cerebral small vessel disease (SVD) is a challenge in remote areas where magnetic resonance imaging (MRI) is not available. Hospital-based studies in high-risk or strokeExpand
Cerebrovascular Complications of Neurosyphilis: The Return of an Old Problem
Neurosyphilis is increasing due to a rise in the number of cases of syphilis in cocaine/crack addicts and in patients with HIV infection. Neurosyphilis is an example of a unique group of chronic CNS d
Thalamic ataxia
SummarySeventeen patients with hemiataxia as a manifestation of thalamic infarction were studied. Hemiataxia had the main clinical characteristics of a “cerebellar type” of ataxia, though it neverExpand
Technical Difficulties Due to Poor Acoustic Insonation during Transcranial Doppler Recordings in Amerindians and Individuals of European Origin. A Comparative Study
Background: There is no information on transcranial Doppler (TCD) failures due to poor insonation among native inhabitants of Latin America. Methods: Seventy Ecuadorian natives and 70 age- andExpand
Temporal bone thickness and texture are major determinants of the high rate of insonation failures of transcranial doppler in amerindians (the Atahualpa Project)
To assess the role of temporal bone characteristics in transcranial Doppler (TCD) insonation failures in Amerindians living in rural Ecuador.
Distribution of Cervicocephalic Atherosclerotic Lesions and Their Correlation with Cardiovascular Risk Factors in a Population of Amerindians. The Atahualpa Project.
BACKGROUND No information is available on the distribution of cervicocephalic atherosclerosis in Amerindians. We aimed to assess the distribution of these lesions and their correlation withExpand
The association of sleep-disordered breathing with high cerebral pulsatility might not be related to diffuse small vessel disease. A pilot study
AbstractBackground In a population-based sampling study conducted in community-dwelling older adults living in rural Ecuador, we aimed to assess the relation among sleep-disordered breathing,Expand
