Filter by:The DELPhi system is a software device that is used for the noninvasive evaluation of brain plasticity and connectivity. The DELPhi software uses EEG and TMS devices as accessories. Standard electro-physiological acquisition is performed using TMS to evoke regional neuronal potentials measured as EEG data. TMS-EEG data is analyzed with regards to conventional, well established characteristics of neuronal network plasticity and connectivity.
TELECAST-TIA is a prospective single-center study evaluating guideline-based transient ischemic attack (TIA) treatment at an Acute Stroke Ready Hospital (ASRH) pre- and post-initiation of a specialist telestroke inpatient rounding service. TELECAST-TIA will study the following clinical endpoints: diagnostic stroke evaluation, secondary stroke prevention, health screening and evaluation, stroke education, inpatient complications, and stroke recurrence rates. Additional relevant non-clinical data will include patient and provider satisfaction scores, transfer patterns, and a cost analysis.
Stroke is a significant medical problem with 150,000 events occurring per year in the UK and incurring healthcare costs of £4 billion per year. Fifty percent of strokes will leave a lasting disability on first manifestation and 10-15% (roughly 16,500 per year) are unheralded ischaemic events in previously asymptomatic Carotid artery disease. Carotid Artery Disease is caused by the formation of an atherosclerotic plaque in the vessel. Stroke or TIA occurs when plaque or adherent thrombus breaks off and embolises to the brain, blocking off its blood supply. Hence, a carotid plaque is said to be symptomatic if it has caused a Stroke or TIA in the territory of the brain supplied by that vessel in the previous six months. Currently, the degree of stenosis (narrowing) of the artery by doppler ultrasound is the main assessment performed. Doppler ultrasound measures stenosis and elevation of blood flow velocity in the artery prior to surgical intervention. However, it has been shown that the degree of stenosis is a poor predictor of stroke as many asymptomatic patients have severe stenosis and many symptomatic patients have moderate stenosis. Stenosis is a two dimensional assessment of a 3-D structure. Other features of the plaque should be considered including the volume of the carotid plaque and its constituents. Carotid Plaque Volume has been measured in 339 individuals, with plaque volume being higher in symptomatic than asymptomatic individuals. In this study, plaque volume did not correlate with stenosis degree. No studies have been conducted measuring the change in carotid plaque volume and morphology following a stroke. This pilot study will perform serial duplex scans on recently symptomatic individuals over a 12 week period and observe the changes in Plaque Volume and morphology. This will attempt to prove that carotid plaque volume is a better predictor of stroke than stenosis. The investigators will also aim to identify other plaque features that may have an important role in predicting stroke risk. Documenting the timescale of change in plaque volume will aid us in defining appropriate timescales for treating the symptomatic population and when those having medical management's risk has returned to baseline. Observing the change in plaque immediately after stroke will improve our knowledge of the changes in plaques that lead to symptoms and may in the future help us predict which patients with asymptomatic carotid stenosis need operation.
This study will test the feasibility of a home blood pressure telemonitoring (HBPTM) system in patients with minor stroke or TIA in the past year. The telemonitoring system will consist of a blood pressure machine and an online survey to submit blood pressure measurements. The investigators want to test whether patients can persistently use the telemonitoring system with ease and whether telephone instructions for blood pressure medications from the research nurse can be correctly understood. A secondary purpose of this study is to look at the effects of telemonitoring in blood pressure and stroke recurrence.
The CARDIOSTROKE is a randomized trial comparing mobile-device assisted control of hypertension together with screening of occult atrial fibrillation to standard care in patients with recent ischemic stroke or transient ischemic attack.
Interventions to improve health behaviour in patients with resent acute stroke are not well established. This study will evaluate the feasibility and effect of an early initiated counselling intervention targeting smoking, physical activity, and adherence to preventive medication, with regular follow-up sessions, in patients with acute minor stroke or transient ischemic attack who are discharged home.
Large-artery stenosis plays an important role in the occurrence of ischemic stroke. The primary purpose of this study is to evaluate the efficacy and safety of intensive antiplatelet therapy versus standard antiplatelet therapy and immediate high-intensity statin therapy (80mg atorvastatin) versus delayed high-intensity statin therapy (40mg atorvastatin) and intensive antiplatelet combined with immediate high-intensity statin therapy (80mg atorvastatin) versus standard antiplatelet combined with delayed high-intensity statin therapy (40mg atorvastatin) in reducing the risk of stroke at 90 days in patients with acute and high-risk symptomatic extracranial or intracranial arterial stenosis.
Fragile brain is the most common phenomenon seen in the patients undergoing CEA. The patients with fragile brain have a high incidence of postoperative brain dysfunction. This study intends to apply EEG monitoring (Sedline) to CEA to investigate whether EEG monitoring can reduce the incidence of postoperative neurological complications in CEA patients and improve their prognosis. 220 patients with CEA were randomly divided into 2 groups. Group S [Sedline monitoring + Transcranial Doppler (TCD) + regional cerebral oxygen saturation (rS02)，n=110] and group C [Bispectral index (BIS)/Sedline monitoring + TCD +rSO2,n=110], recording intraoperative and postoperative conditions, neuropsychology scale assessment, blood examination and imaging examination. The incidence of postoperative neurological complications was compared between the two groups.
The effectiveness of outpatient management of minor TIAs and strokes in the context of a dedicated outpatient pathway with specialized care has been demonstrated and has resulted in an 80% decrease in stroke in the year followed the AIT (EXPRESS and SOS-TIA studies) At the same time, few studies have been conducted on their economic interest and none in France. Patient's typology (younger patient, no sequel, no disability) with Transient ischemic attack (TIA) and minor stroke (MS) makes them compatible with ambulatory management.
The TASK (Treating Anxiety after StroKe) trial is a feasibility randomized controlled trial. It aims to evaluate the feasibility of i) web-enabled trial procedures, and ii) the TASK intervention in stroke and TIA patients
