15 صفحه اولTranscranial doppler sonography diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine
Background: An imbalance of the cerebrovascular response during functional activation of the brain has been postulated as a factor in the pathophysiology of migraine. The purpose of this study was to determine the transcranial doppler sonography (TDS) diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine. Methods: This study was carried out on 46 pa...
متن کاملInterhemispheric comparisons of cerebral blood flow velocity changes during mental tasks with transcranial Doppler sonography.
OBJECTIVE The purpose of this study was to evaluate hemispheric asymmetry of cerebral blood flow changes during various mental tests by applying transcranial Doppler sonography (TCD) to simultaneously monitor bilateral cerebral blood flow velocity changes. METHODS Twenty-one participants without cerebrovascular disease performed 3 left hemispheric tasks (reading, calculation, and color scalin...
متن کاملLateralization of cerebral blood flow velocity changes during cognitive tasks. A simultaneous bilateral transcranial Doppler study.
BACKGROUND AND PURPOSE Transcranial Doppler ultrasonography (TCD) permits the assessment of cognitively induced cerebral blood flow velocity (BFV) changes. We sought to investigate the lateralization of BFV acceleration induced by a variety of cognitive tasks and to determine the influence of age, gender, IQ, and quality of the performance on the relative BFV changes. METHODS Simultaneous bil...
