BACKGROUND AND PURPOSE Microemboli have been implicated in the etiology of neuropsychological deficits after cardiopulmonary bypass. This study examined the incidence of high-intensity transcranial signals (microemboli) and their relation to changes in neuropsychological performance after surgery. METHODS Transcranial Doppler ultrasonography was used to(More)
Many studies have provided data showing that family history of stroke (FHS) is associated with an increased risk of stroke. The association of the FHS with the various stroke subtypes has not been adequately studied. The purpose of this study was to assess the association of the FHS with the two major stroke types (cerebral haematomas and ischaemic strokes)(More)
SUMMARY Under normal conditions, motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation increase in amplitude if the subject exercises the examined muscle immediately before recording. The authors examined the effect of nonfatiguing exercise on the amplitude of MEPs on 42 psychiatric, medicated inpatients (14 with depression, 14 with(More)
To quantitate embolic risk we studied a retrospective series of 61 patients with strictly defined bacterial endocarditis. Eighteen patients had neurological complications attributable to cerebral embolism. Seventeen embolic episodes occurred prior to antibiotic treatment and 8 episodes after its commencement. The rate of embolism per patient-week during a(More)
Clinical studies of the effects of rubidium ions on the course of manic-depressive illness are reported. It seems that rubidium tends to increase the length of manic phases and possibly reduces the extremes of mood. Rubidium did not seem to produce any severe side effects in the dose administered, but it has a long biological half-life and caution is still(More)
The aim of the current study was to investigate the characteristics of Greek inmates that were taking regularly benzodiazepines (BZDs) at therapeutic doses, in the high-security prison of Patras, Greece. Three hundred eighty-four prisoners were included in the study. BZD users (BUs, n = 192), compared with non-BZD users (NBUs, n = 192), were significantly(More)
Lithium salts administered in therapeutic doses to four subjects who were kept on controlled diets increased up to fivefold the urinary output of some dicarboxylic acids. Some of the acids affected are intermediates in the tricarboxylic acid cycle, others are chemically similar but not directly related in metabolic terms. This is probably a direct effect on(More)
