Cortical neuromodulation modifies cerebral vasomotor reactivity.
BACKGROUND AND PURPOSE Cerebral vasomotor reactivity (VMR) is a capability of cerebral vessels to dilate in response to hypercapnia. Transcranial direct current stimulation (tDCS) effects on cerebral hemodynamics have been poorly studied. METHODS Ten healthy subjects underwent anodal/cathodal tDCS on the left motor cortex. Before and after tDCS, VMR assessment by transcranial Doppler and an e...
متن کاملCerebral hypercapnia-induced vasomotor reactivity in migraine with and without aura: a case-control study
Abstract Background: Dysfunction of the autonomic nervous system has long been a subject of considerable debate and a large number of studies have disclosed contradictory results. The aim of this study was to compare cerebral vasomotor reactivity in migraine with aura (MWA) patients with migraine without aura (MWO) ones. Methods: Ten MWA patients (7 females and 3 males mean age: 39.70 years, S...
متن کاملReduced vasomotor reactivity in cerebral microangiopathy : a study with near-infrared spectroscopy and transcranial Doppler sonography.
BACKGROUND AND PURPOSE Reduction of cerebral blood flow and vasomotor reactivity (VMR) are thought to play an important role in the pathogenesis of cerebral microangiopathy. The aim of our study was to determine whether near-infrared spectroscopy (NIRS) can detect a reduced VMR in patients with microangiopathy, whether NIRS reactivities correlate with VMR assessed by transcranial Doppler sonogr...
متن کاملCerebral vasomotor reactivity and risk of mortality: the Rotterdam Study.
BACKGROUND AND PURPOSE Accumulating vascular pathology in cerebral arteries leads to impaired cerebral vasomotor reactivity. In turn, impaired cerebral vasomotor reactivity is a risk factor for stroke in clinical populations. It remains unclear whether impaired cerebral vasomotor reactivity also reflects more systemic vascular damage. We investigated whether cerebral vasomotor reactivity is ass...
متن کاملLeukocyte involvement in vasomotor reactivity of the cerebral vasculature.
A ctivation of leukocytes may play a part in the / \ complex pathophysiological cascade leading to A.V. vasomotor reaction in cerebral arteries. In this issue of Stroke, Akopov et al report changes in endothelium-dependent relaxation by intravascular chemical leukocyte activation involving the cerebral circulation. This interesting study highlights a potential role for leukocytes in the modulat...
