... transcranial Doppler (fTCD) could provide useful data in the evaluation of these presymptomatic FD patients. Methods: A cohort of 12 adult FD patients from families with the classical phenotype of the disease was evaluated with fTCD in the posterior cerebral artery. Results: Compared to healthy controls...

... deficit after stroke. Methods: We included 65 patients with non-lacunar stroke admitted to a rehabilitation hospital within 4 weeks from the event. An evaluation of cerebrovascular reactivity to hypercapnia was performed with transcranial Doppler ultrasonography using the breath-holding index (BHI...

... small vessel disease (CSVD), the pulsatility of cerebral arteries, and the stiffness of large arteries in patients with lacunar infarction (LI). Methods: Subjects included 120 patients with LIs, who underwent MRI, transcranial Doppler ultrasonography, and brachial ankle pulse wave velocity (BaPWV). We...

...Salma H. Khaleel; Iman M. Bayoumy; Lobna M. El-Nabil; Ramez Reda Moustafa Objective: To assess the cerebral vasomotor response to ipsilesional repetitive transcranial magnetic stimulation (rTMS) on transcranial Doppler (TCD) in patients with recent ischemic stroke without carotid occlusive disease...

...E. Vicenzini; S. Pro; S. Strano; P. Pulitano; M. Altieri; V. Di Piero; G.L. Lenzi; N. Accornero; O. Mecarelli Background: In neurally mediated syncope a ‘typical’ EEG pattern during hyperventilation (HV) may be observed. This study aimed to investigate transcranial Doppler (TCD) and EEG variations...

...-enhanced transcranial Doppler (TCD). The diagnosis of migraine was made according to the 2004 International Headache Classification. Results: Sixteen CADASIL patients were tested; 6 had MA. Four patients displayed an RLS on contrast-enhanced TCD examination. Three of these patients had MA. Both patients...

... to carotid duplex ultrasound and transcranial Doppler. Cerebrovascular reactivity was assessed on both middle cerebral arteries simultaneously calculating (a) the total vasomotor range (VMR) measured after breath holding and hyperventilation and (b) the rate of change (VMR/CO 2 ) after breath holding...

...Leandro Provincial; Paolo Minciotti; Gabriella Ceravolo; Franco Angeleri; Claudio M. Sanguinetti Transcranial Doppler monitoring of the flow velocity at the level of the middle cerebral artery was performed in 40 demented patients, 20 with multi-infarct dementia (MID) and 20 with senile dementia...

... contralateral stenosis and/or no collateral flow capacity through the anterior communicating artery are likely to be at higher risk during surgery. We examined a series of 52 patients pre- and postoperatively with transcranial Doppler (TCD) and compared the results to perioperative stump pressures. Our...

...Giovanni Orlandi; Giuliano Parenti; Alessandra Bertolucci; Luigi Murri 124 carotid arteries of 62 patients with unilateral or bilateral carotid stenosis proven by selective angiography were investigated by transcranial Doppler to detect high-intensity transient signals (HITS) in the middle cerebral...

...) and vascular dementia (VaD). The aim of this study was to explore cerebral hemodynamics by transcranial Doppler in VaD and AD, compared with age-matched control subjects. Methods: Transcranial Doppler was investigated in all patients in the basal condition. Cerebral vasoreactivity to hyper- and hypocapnia...

... older than 80 years treated with TPA and compared them with younger stroke patients. Methods: We studied patients treated with intravenous TPA and divided them into younger (<80 years) and older (≧80 years) groups for comparison. Diagnostic transcranial Doppler was completed before bolus...

... Doppler ultrasonography. Valsalva maneuver (VM) permitted assessment of cerebral autoregulatory function by provoking blood pressure (BP) changes. To develop a path-physiological approach for vasomotor reactivity of cerebral syncope, the authors combined these maneuvers (HUT/transcranial Doppler/VM...

... of MES with neuropsychiatric lupus may support the possible contribution of MES to the complex pathophysiology of this syndrome. More importantly, detection of MES on transcranial Doppler monitoring might suggest a high risk of involvement of the central nervous system in SLE, and could be used...

... in subjects with migraine. The aim of our study was to determine the prevalence of RLS in CADASIL with and without migraine. Methods: We performed transcranial Doppler with gaseous contrast in 5 members of an Italian family with CADASIL, diagnosed by means of genetic and skin biopsy criteria. We then compared...

...Fabrizio Vernieri; Nicola Rosato; Flavia Pauri; Francesco Tibuzzi; Francesco Passarelli; PaoloMaria Rossini We simultaneously performed near infrared spectroscopy (NIRS) and transcranial Doppler (TCD) to evaluate the effects of hypercapnia as well as of scalp ischemia on the blood flow at two...
