Start or STop Anticoagulants Randomised Trial (SoSTART)

Intracranial HemorrhagesIntracranial Hemorrhage8 more

Primary research question: For adults surviving spontaneous (non-traumatic) symptomatic intracranial haemorrhage with persistent/paroxysmal atrial fibrillation/flutter (AF), does starting full treatment dose oral anticoagulation (OAC) result in a beneficial net reduction of all serious vascular events compared with not starting OAC? Trial design: Investigator-led, multicentre, randomised, open, assessor-masked, parallel group, clinical trial of investigational medicinal product (CTIMP) prescribing strategies. Investigators plan for a pilot phase, followed by a safety phase.

Oxford Haemodynamic Adaptation to Reduce Pulsatility Trial

Small Vessel Cerebrovascular Disease

Chronic damage to small blood vessels deep in the brain is seen in half of patients over the age of 60 and almost all patients over the age of 80, and is responsible for up to a third of strokes and almost half of patients with dementia. However, there is limited evidence for how small vessel disease develops and no specific treatment. One potential explanation is that greater pulsations in blood pressure are transmitted to the brain through stiff blood vessels, resulting in increased pressure hitting the brain each time the heart beats and reduced blood flow between heart beats. Sildenafil is used to open up blood vessels (a vasodilator) in patients with erectile difficulties or poor blood supply to the lungs. This trial will test sildenafil (50mg, thrice daily) against placebo and a similar drug (cilostazol 100mg, twice daily) in 75 patients with previous stroke or mini-stroke and small vessel disease, given in random order to every participant for 3 weeks each. It will primarily assess changes in pulsations of blood flow to the brain on each tablet, measured with an ultrasound scanner (transcranial ultrasound). To understand why any changes occur, we will also measure the stiffness of arteries, the blood pressure at the heart and how much blood vessels in the brain open up when participants breathe air with added carbon dioxide (6%), using ultrasound in all participants and on MRI brain scans in 30 patients. This study will test whether a vasodilator used in other conditions with a good safety profile can reduce pulsations in blood flow to the brain, to assess whether it is a good candidate drug to reduce the progression of small vessel disease in future clinical trials. This would be the first effective treatment for a condition associated with a very high burden of disability.

LACunar Intervention (LACI-2) Trial-2

Cerebral Small Vessel DiseasesStroke1 more

About 35,000 people each year in the UK have a type of stroke, called 'lacunar' or 'small vessel' stroke, which is different to other common types of stroke and for which there is no proven treatment. It is thought that small vessel stroke is caused by damage to the lining of the tiny blood vessels deep inside the brain that stops them functioning normally. This not only causes stroke but, perhaps more importantly, causes problems with thinking and walking, possibly causing up to 45% of all dementias either on its own, or mixed with Alzheimer's disease (about 350,000 patients in the UK). Some drugs that are commonly used in other blood vessel diseases may help improve small vessel function and prevent worsening of brain damage. One drug (cilostazol) has been tested in patients with stroke in the Asia Pacific countries but not on dementia; the other drug (isosorbide mononitrate) is widely used in the UK for heart disease but not stroke. The investigators want to set up a clinical trial to test if the study methods are practical so that patients and trial centres can follow the procedures, and to confirm how many patients have more stroke-like symptoms or experience worsening of their thinking skills. This information is needed to be sure that a very large clinical trial to find out if these drugs can prevent worsening of small vessel disease will be possible.

Neuroimaging Combining Biomarkers for Identifying Long-term Cognitive Dysfunction and Delirium

Postoperative Cognitive DysfunctionPostoperative Delirium2 more

Postoperative Cognitive Dysfunction(POCD) is commonly seen in cardiac surgery, which may lead to poor pognosis. Cerebral small vessel disease(CVSD) is refer as the main resource of delirium among elderly people. In the study, CVSD will be diagnosed using multimodal MRI. And we want to select a high correlating COPD biomarker through CyTOF. We also want to investigate a medical model to select the high risk patients who may suffer from POCD after cardiac surgery.

Clinical Observation for the Therapeutic Effect of mNGF on Cognitive Decline in Cerebral Small Vessel...

Cerebral Small Vessel Diseases

This study was a multicenter, prospective, randomized controlled trial. In this study, 510 patients with cognitive impairment of cerebral small vessel disease who met the inclusion criteria are randomly included in multiple centers and randomized into two groups (standard treatment group and mouse nerve growth factor addition treatment group). The standard treatment group is treated with conventional drugs and cholinesterase inhibitors. In addition to the above treatment, the mouse nerve growth factor addition treatment group is administered with nerve growth factor 20 μg (9000 U)/vial for 14 consecutive days, intramuscularly once a day. Systematic clinical evaluation of patient cognitive function is performed at baseline, 14-day, and 3-month follow-up, and imaging (MR) is also evaluated twice at baseline, 14-day, and 3-month follow-up. At last observe the clinical effect of mouse nerve growth factor on cognitive impairment of cerebral small vessel disease.

Trial of Remote Ischemic Pre-conditioning in Vascular Cognitive Impairment

Vascular DementiaCerebral Small Vessel Diseases2 more

Cerebral small vessel disease is a common cause of cognitive impairment. Remote ischemic pre-conditioning (RIC) is a technique to induce brief periods of limb ischemia-reperfusion that is hypothesized to increase tolerance of the brain to hypoperfusion and increase cerebral blood flow. Patients with cognitive impairment, preserved basic activities of daily living, and brain computed tomography (CT) or magnetic resonance imaging (MRI) evidence of confluent white matter hyperintensities or multiple brain infarcts will be randomized to either RIC performed once a day on one arm, or twice per day on one arm, for 30 days, to test tolerability and effects on MRI markers of blood flow.

The Efficacy of DL-NBP in Patients With Mild Subcortical Ischemic Vascular Dementia

Subcortical Vascular DementiaCerebral Small Vessel Diseases

This is a 48-week, double-blind, randomized, placebo-controlled study. Sixty-four patients are randomly assigned to take NBP (600mg per day) or placebo for 48 weeks, with 32 patients in each treatment group. Anti-dementia treatment-naive patients meet the inclusion/exclusion criteria are enrolled. Patients are assigned to NBP will take 200mg tid daily. Patients are visited at baseline, as well as 4, 12, 24, 36, 48weeks after baseline. Safety data is recorded until an additional 30 days after the last treatment (48 weeks). The primary outcomes include cognitive function and activities of daily living (ADL). All subjects are assessed at baseline, 4w, 12w,24w, 36w intermittent visit and 48w endpoint with the Auditory Verbal Learning Test (AVLT), the Brief Visuospatial Memory Test-Revised (BVMT-R), the Symbol Digit Modalities Test (SDMT), the Trail Making Test-A/B (TMT-A/B), the Benton Judgment of Line Orientation (JLO), the verbal fluency test, the Boston Naming Test (BNT), the Controlled Oral Word Association Test (COWAT), the Stroop test, the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA) and the ADL. The secondary outcomes include the global function and behavioral and psychological symptoms of dementia (BPSD), which are evaluated with the Clinical Dementia Rating (CDR) and the Neuropsychiatric Inventory (NPI), respectively. Independent raters who are blinded to patients' distribution are assigned to assess the participants. The exploratory outcomes are markers of vascular regulation, including circulating endothelial progenitor cells (EPCs), white matter hyperintensities (WMH) on MRI, cerebral blood flow (CBF) measured with transcranial Doppler (TCD) and arterial spin labeling (ASL) MRI, and parameters of carotid duplex ultrasonic (CDU). In addition, apolipoprotein E (APOE) polymorphism and plasma biomarkers are also detected. Safety are assessed at each visit.
