Many neuropsychological investigations of human memory have focused on the amnesic deficits of alcoholic Korsakoff's syndrome. Structural neuroimaging suggests that the syndrome results from midline diencephalic damage, but functional neuroimaging has the potential to reveal additional neuropathology that may be responsible for cognitive dysfunction.(More)
Volume-of-interest (VOI) extraction for radionuclide and anatomical measurements requires correct identification and delineation of the anatomical feature being studied. We have developed a toolset for specifying three-dimensional (3-D) VOI's on a multislice positron emission tomography (PET) dataset. The software is particularly suited for specifying(More)
Both increased and decreased testosterone levels have been reported to correlate with poor outcome after acute ischemic stroke. The present study focused on the role of testosterone during recovery from neurological deficits in a rat focal ischemia model. Castrate male rats were subjected to behavioral tests after 90 min of middle cerebral artery occlusion(More)
Manipulation of inhaled gases during ischemia/reperfusion is a potential novel therapy for acute stroke. We previously found that treatment with a mixture of 70%/30% helium/oxygen (heliox) or 100% oxygen protects the brain against acute focal ischemia-reperfusion injury. This study evaluates the potential neuro-protective effects of delayed heliox treatment(More)
A 3-year-old boy who presented with flaccid weakness of the right lower limb 1 week after treatment for an acute attack of asthma is described. Sensation was normal. Electromyography suggested anterior horn cell damage and persisting weakness. These features suggested a diagnosis of Hopkins syndrome. Complement fixation test titer and agglutination test(More)
INTRODUCTION Most patients with acute intracerebral hemorrhage (ICH) have very high blood pressure (BP) on presentation, but it is unclear whether such pressure elevation is the cause or a consequence of the ICH. This controversy could be clarified by determining the exact temporal relationship between the BP elevation and the onset of the ICH. Several case(More)
