  • Lumbar Drain vs Extraventricular Drain to Prevent Vasospasm in Subarachnoid Hemorrhage

    open to eligible people ages 18-110

    Vasospasm is a common complication after rupture of intracranial aneurysms causing devastating neurologic deficits and death. Vasospasm has been directly associated with the amount of subarachnoid blood inside the basal cisterns. Prior literature has attempted to refine treatment of ruptured intracranial aneurysms but does not have clear guidelines on the optimal method to drain subarachnoid blood. Two methods, extraventricular drain (EVD) and lumbar drain (LD) have been compared retrospectively yet remain controversial as to which method is optimal in reducing subarachnoid blood and preventing vasospasm. This study would be a prospective randomized trial in which patients would be assigned to EVD or LD and observed to see if one method of intervention is associated with preventing clinical vasospasm, decreasing subarachnoid blood, shortening overall ICU stay, and reducing the need for a permanent ventriculoperitoneal shunt. The conclusions of this study may identify an optimal treatment modality to benefit all future patients with ruptured intracranial aneurysms.

  • Transnasal Sphenopalatine Ganglion Block for Treatment of Acute Subarachnoid Hemorrhage Associated Headache

    open to eligible people ages 18-100

    The study titled "Transnasal sphenopalatine ganglion block for treatment of acute subarachnoid hemorrhage associated headache" is a randomized controlled pilot study aimed at evaluating the efficacy of a transnasal sphenopalatine ganglion (SPG) block in addition to standard pain medication for reducing headache severity in patients with acute subarachnoid hemorrhage (aSAH). The study also examines whether this intervention can reduce opioid requirements during hospitalization and upon discharge.

  • Determinants of Incident Stroke Cognitive Outcomes and Vascular Effects on RecoverY

    open to eligible people ages 18 years and up

    The overall goal of the DISCOVERY study is to better understand what factors contribute to changes in cognitive (i.e., thinking and memory) abilities in patients who experienced a stroke. The purpose of the study is to help doctors identify patients at risk for dementia (decline in memory, thinking and other mental abilities that significantly affects daily functioning) after their stroke so that future treatments may be developed to improve outcomes in stroke patients. For this study, a "stroke" is defined as either (1) an acute ischemic stroke (AIS, or blood clot in the brain), (2) an intracerebral hemorrhage (ICH, or bleeding in the brain), (3) or an aneurysmal subarachnoid hemorrhage (aSAH, or bleeding around the brain caused by an abnormal bulge in a blood vessel that bursts). The investigators hypothesize that: 1. The size, type and location of the stroke play an important role in recovery of thinking and memory abilities after stroke, and pre-existing indicators of brain health further determine the extent of this recovery. 2. Specific stroke events occurring in individuals with underlying genetic or biological risk factors can cause further declines in brain heath, leading to changes in thinking and memory abilities after stroke. 3. Studying thinking and memory alongside brain imaging and blood samples in patients who have had a stroke allows for earlier identification of declining brain health and development of individualized treatment plans to improve patient outcomes in the future.

  • NOninVasive Intracranial PrEssure from Transcranial DoppLer Ultrasound Development of a Comprehensive Database of Multimodality Monitoring Signals for Brain-Injured Patients

    open to eligible people ages 18 years and up

    This is an observational study in neurocritical care units at University of California San Francisco Medical Center (UCSFMC), Zuckerberg San Francisco General Hospital (ZSFGH), and Duke University Medical Center. In this study, the investigators will primarily use the monitor mode of the Transcranial Doppler (TCD, non-invasive FDA approved device) to record cerebral blood flow velocity (CBFV) signals from the Middle Cerebral Artery and Internal Carotid Artery. TCD data and intracranial pressure (ICP) data will be collected in the following four scenarios. Each recording is up to 60 minutes in length. Multimodality high-resolution physiological signals will be collected from brain injured patients: traumatic brain injury, subarachnoid and intracerebral hemorrhage, liver failure, and ischemic stroke. This is not a hypothesis-driven study but rather a signal database development project with a goal to collect multimodality brain monitoring data to support development and validation of algorithms that will be useful for future brain monitoring devices. In particular, the collected data will be used to support: Development and validation of noninvasive intracranial pressure (nICP) algorithms. Development and validation of continuous monitoring of neurovascular coupling state for brain injury patients Development and validation of noninvasive approaches of detecting elevated ICP state. Development and validation of approaches to determine most likely causes of ICP elevation. Development and validation of approaches to detect acute cerebral hemodynamic response to various neurovascular procedures.

  • Stroke Recovery Initiative - Registry for Stroke Research Studies

    open to eligible people ages 18 years and up

    The Stroke Recovery Initiative is a nation-wide participant recruitment registry that connects people who have had a stroke with researchers who are working to develop new approaches to improve recovery after stroke.

  • GTX-104 Compared with Oral Nimodipine in Patients with ASAH

    Sorry, in progress, not accepting new patients

    The purpose of this study is to deliver nimodipine via IV directly into the bloodstream and to determine if this is as safe and tolerable as oral nimodipine capsules.
