BACKGROUND AND PURPOSE Functional recovery after cerebral infarction is a complex phenomenon that depends on various factors. The aim of this study was to investigate changes in cerebral perfusion during motor activity in stroke patients with very early recovery of motor function. METHODS We included 9 consecutive patients hospitalized for acute-onset(More)
In this study, we have used paired transcranial stimulation of the motor cortex to test the hypothesis that cortical inhibition is decreased in juvenile myoclonic epilepsy (JME). The double shock technique was adopted here because it offers a means for highlighting abnormal inhibitory mechanisms. From previous experiments performed on healthy subjects, it(More)
We compared sleep parameters in mentally retarded infantile autism (MRIA) and mentally retarded Down's syndrome (MRDS) by means of polysomnography, evaluating traditional analysis with particular attention to the phasic components in each disorder. Data were compared with those obtained in normal subjects matched for age and sex. Mental age, Intellectual(More)
Our objective was to determine, in three separate studies, the effects of controlled-release carbamazepine (CBZ-CR), lamotrigine (LTG), and gabapentin (GBP) on nocturnal sleep in epilepsy. Antiepileptic drugs (AEDs) control seizures and also modify hypnic structure. Despite widespread clinical use, their effects on sleep are not well known. PSG was(More)
BACKGROUND AND OBJECTIVE A clear association among snoring, sleep apnea, and increased risk of stroke has been shown by previous studies. However, the possible role played by sleep apnea in the pathogenesis of cerebrovascular disease is subject to debate. To evaluate the influence of hemodynamic changes caused by obstructive sleep apnea syndrome (OSAS), we(More)
BACKGROUND It is uncertain whether Helicobacter pylori is associated with ischemic syndromes and whether this association is mediated by the induction of atherosclerosis. In this study, we tested the hypothesis that atherosclerotic stroke shows a selective association with virulent H pylori strains. METHODS AND RESULTS The seroprevalence of infection by H(More)
The authors performed a double-blind, placebo-controlled study in 28 patients to evaluate the effects of sildenafil on cerebral hemodynamics. A significant improvement of cerebrovascular reactivity, without any modification of other variables, was recorded 1 hour after the administration of 50 mg sildenafil. Further investigations are needed to evaluate(More)
BACKGROUND AND PURPOSE Epidemiological studies have suggested a pathophysiological link between sleep apnea syndrome and cerebrovascular diseases. The mechanism by which sleep disturbance can affect the predisposition to developing stroke is not clear. The aim of this study was to investigate whether patients with obstructive sleep apnea syndrome have an(More)
Several studies have demonstrated a clear association between snoring, sleep apnoea and increased risk of stroke. However, the possible role of sleep apnoea in the pathophysiogenetic mechanisms of cerebrovascular disease is still unknown. Our aim in this study was to investigate cerebral haemodynamic changes during the waking state in eight patients with(More)
