Mild Cognitive Impairment (MCI) causes slight but noticeable disruption in cognitive systems, primarily executive and memory functions. However, it is not clear if the development of sequence learning is affected by an impaired cognitive system and, if so, how. The goal of our study was to investigate the development of probabilistic sequence learning, from(More)
Tonabersat is a novel putative migraine prophylactic agent with an unique stereospecific binding site in the brain. Tonabersat has been shown, in animal models, to inhibit experimentally induced cortical spreading depression, the likely underlying mechanism for migraine aura, and cerebrovascular responses to trigeminal nerve stimulation. The aim was to(More)
BACKGROUND AND PURPOSE Patients with stroke are at substantial risk of thromboembolic complications and therefore require antithrombotic prophylaxis. To show the noninferiority of the low-molecular-weight heparin certoparin to unfractionated heparin (UFH) for the prevention of thromboembolic complications, we performed a randomized, double-blind,(More)
BACKGROUND Clinical and experimental studies suggest that increased activity of semicarbazide-sensitive amine oxidase (SSAO) and the production of cytotoxic metabolites (e.g., formaldehyde and hydrogen peroxide) may play an important role in the pathogenesis of atherosclerosis. The present study was designed to assess the relationship between the increased(More)
The wall thickness of the atherosclerotic common carotid artery may be quantitatively assessed by measuring of the intima-media thickness with high resolution B-mode ultrasonography. The reliability and reproducibility of a simple non-invasive planimetric method has been assessed. The interobserver, intraobserver, interreading and cardiac cycle dependent(More)
In order to compare the extent of early carotid atherosclerosis between patients with single vascular risk factors (smoking = SMO or hypertension = HYP) and risk-free normal subjects ( = HCS), we used intimal-medial wall thickness (IMT) measurements of the common carotid artery. The age- and sex-adjusted mean IMTs were significantly higher in the HYP and(More)
INTRODUCTION Chronic cerebral hypoperfusion is a risk factor for the development of certain types of dementia. Mild cognitive impairment is a stage of predementia condition, because the symptoms are similar but not as severe as the symptoms in patients with dementia. Vinpocetine, due to its complex mechanism of action, has an important role in the(More)
The clinical history of a 65-years-old man is described by authors with typical symptoms of the Kawasaki disease. The clinical picture of this syndrome is characterized by high fever, characteristic changes of mucous membrane and skin and enlargement of cervical lymph nodes. The disease is most frequent in Japan and very rare after the age of eighteen. The(More)
A prospective comparison was completed between duplex sonography and intraarterial digitalized subtraction angiography of the carotid and vertebral arteries. The sensitivity, specificity and overall accuracy of the duplex ultrasound were evaluated. In 85 patients 169 sides were investigated. The vessels were divided into normal, 1-24%, 25-49%, 50-74%,(More)
