Filter by:Traumatic acute subdural haematomas (ASDHs) are common pathological entity in neurosurgical practice . The frequency of (ASDHs) has been proposed as approximately 10-20% of patients admitted with traumatic brain injury(TBI) .Approximately two -thirds of patient with TBI undergoing emergency cranial surgery have an acute subdural haematoma evacuated . Two common causes of traumatic ASDH: accumulation of blood around parenchymal laceration , usually frontal and temporal lobes and there is usually severe underlying brain injury .The second cause is surface or bridging vessel torn from cerebral acceleration - deceleration during violent head motion .
By combination of plasma (Aβ40, Aβ42, total tau, and phosphorylated tau, etc.), genetic (ApoE ε2 or ε4 allele), MRI (cerebral perfusion, microbleeds, cortical superficial siderosis, enlarged perivascular space, etc.) and PET imaging (amyloid and tau) biomarkers, the study aims to 1. Enhance the diagnostic potentials of the radiological biomarkers by combining MRI and amyloid PET in CAA patients. 2. Investigate the biological pathogenesis in CAA patients using the less invasive plasma biomarkers and to correlate with structural and function imaging, including MRI, amyloid and tau imaging. 3. Study the characteristics of long-term progression of amyloid deposition in CAA patients using the radiological, biochemical and genetic biomarkers. 4. Study the prognosis predicting markers.
To assess whether edoxaban (60/30 mg daily) compared to non-antithrombotic medical therapy (either no antithrombotic therapy or antiplatelet monotherapy) reduces the risk of stroke (composite of ischemic, hemorrhagic and unspecified stroke) in high-risk atrial fibrillation (CHA2DS2-VASc ≥2) patients with previous intracranial hemorrhage.
In this study, investigators look at a different type of technology that might help to avoid having to perform CT scans in certain patients suspected of having a head injury. Near-infrared spectroscopy (NIRS) uses a specific light wavelength to determine if there is bleeding into the head as a result of trauma. Investigators will study NIRS, using a device called the Infrascanner model 2000, to determine if it is as good at detecting bleeding in the head as CT scan, which is the current gold standard. Investigators will try to determine if NIRS can rule in or rule out bleeding into the head, and perhaps this can help to avoid subjecting these youth to the potentially harmful effects of radiation. Investigators will also study how easy it is to use NIRS so that it might become a standard part of the workup for children with suspected head injury.
This study was designed to explore the influencing factors of spontaneous intraparenchymal hemorrhage's prognosis and develop predictive models for poor prognosis by establishing a cohort of spontaneous intraparenchymal hemorrhage (including both of the supratentorial intracerebral hemorrhage and cerebellar hemorrhage), and analyzing the correlation between collected variables and patients' outcomes.
This is a pilot study to evaluate clinical predictors of intracranial bleeding in elderly patients who present to the emergency department (ED) after a fall. The aim is to assess feasibility and rate of patient recruitment, patient follow up, and to establish a point estimate for the incidence of intracranial bleeding in the investigator's population. Currently there are no guidelines for ED physicians to assess the pretest probability of intracranial bleed in these patients, and no safe way to exclude a bleed without CT.
This study will evaluate the feasibility of dual tDCS to improve arm motor function in chronic stroke patients. In addition it will collect pilot data on the blood biomarkers associated with treatment effect.
This study was aimed at patients with newly diagnosed stroke / TIA associated with nonvalvular atrial fibrillation. We will observe the effect of early using rivaroxaban anticoagulation on hemorrhagic transformation, and explore the predictive value of multi-mode MRI infarct volume / MMP-9 on hemorrhagic transformation after anticoagulation therapy.
Falls are the leading cause of traumatic death in the elderly with head injury causing half of these deaths. Each year, one in three adults over the age of 65 (seniors) fall, and half of these seniors seek treatment at a hospital emergency department (ED). There is a major evidence gap in the study of brain injury diagnosis in seniors, which is problematic for emergency physicians since the number of fall-associated head injuries is rising. ED diagnostic tools for risk stratification of these patients do not exist. The investigators will derive a novel ED clinical decision rule for detecting traumatic intracranial bleeding which will standardize the approach to head CT scans. Once validated, the investigators will optimize patient care by ensuring that intracranial bleeding is identified early. By reducing the use of head CT, this decision rule will lead to health care savings and streamlined, patient-centered ED care.
The primary aim of the study is to investigate the relationships among FVIII, t-PA/PAI-1, MMP-9 levels, and intracranial hemorrhage after thrombolysis with alteplase using a combined analysis.
