Brain stem infarction and diaschisis. A SPECT cerebral perfusion study.
BACKGROUND AND PURPOSE We studied six patients suffering from pure, unilateral brain stem infarction to explore the association of remote cerebral and cerebellar blood flow changes with damage at different sites of this region of the brain. METHODS We used single-photon emission computed tomography and [123I]iodoamphetamine to measure regional differences in tracer uptake. Qualitative image a...
متن کاملDiaschisis with cerebral infarction.
Fifteen patients admitted to Philadelphia General Hospital with acute strokes had repeated measurements of cerebral blood flow measured by the 133Xenon inhalation method. A progressive decline in cerebral blood flow in both hemispheres was observed during the first week after infarction in twelve of these patients. This decline could be partially explained by loss of autoregulation, but could n...
متن کاملIpsilateral hypohidrosis in brain stem infarction.
BACKGROUND AND PURPOSE The brain stem is the most important autonomic processing center, but very little attention has been given to clinical manifestations of autonomic failure in brain stem stroke. Our purpose was to evaluate the prevalence, characteristics, and prognostic significance of sweating dysfunction in brain stem infarctions. METHODS We carried out a prospective study using quanti...
متن کاملSilent subcortical brain infarction
Introduction: The silent brain lesions detected by MRI were fairly common not only in first-ever stroke but also in normal elderly subjects. Some recent studies show the possible role of silent sub-cortical brain infarction in ischemic stroke. The aim of this study was to evaluate the frequency of silent sub-cortical brain infarction in acute first-ever ischemic stroke. Methods: In this descrip...
متن کاملNo evidence for transhemispheric diaschisis after human cerebral infarction.
Forty-four studies of regional cerebral blood flow (rCBF), fractional oxygen extraction (rOER) and oxygen consumption (rCMRO2) were made on twenty-five patients with recent internal carotid artery territory infarcts. The purpose was to study flow-metabolism relationships in the contralateral hemispheres, and to investigate whether contralateral rCMRO2 was depressed as a result of the recent inf...
