We aim to determine whether cognitive impairment attributable to cerebral hemodynamic impairment in patients with high-grade asymptomatic carotid artery stenosis is reversible with restoration of flow. To accomplish this aim CREST-H will add on to the NINDS-sponsored CREST-2 trial (parallel, outcome-blinded Phase 3 clinical trials for patients with asymptomatic high-grade carotid artery stenosis which will compare carotid endarterectomy plus intensive medical management (IMM) versus IMM alone (n=1,240), and carotid artery stenting plus IMM versus IMM alone (n=1,240) to prevent stroke and death). CREST-H addresses the intriguing question of whether cognitive impairment can be reversed when it arises from abnormal cerebral hemodynamic perfusion in a hemodynamically impaired subset of the CREST-2 -randomized patients. We will enroll 500 patients from CREST-2, all of whom receive cognitive assessments at baseline and yearly thereafter. We anticipate identifying 100 patients with hemodynamic impairment as measured by an inter-hemispheral MRI perfusion "time to peak" (TTP) delay on the side of stenosis. Among those who are found to be hemodynamically impaired and have baseline cognitive impairment, the cognitive batteries at baseline and at 1 year will determine if those with flow failure who are randomized to a revascularization arm in CREST-2 will have better cognitive outcomes than those in the medical-only arm compared with this treatment difference for those who have no flow failure. We hypothesize that hemodynamically significant "asymptomatic" carotid disease may represent one of the few examples of treatable causes of cognitive impairment. If cognitive decline can be reversed in these patients, then we will have established a new indication for carotid revascularization independent of the risk of recurrent stroke. A Study to Analyze NMS-03305293 and Temozolomide in Adult Patients with Recurrent Glioblastoma Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz. The objectives of this study are to determine the Maximum Tolerated Dose (MTD) and the Recommended Phase 2 Dose (RP2D) of NMS-03305293 in combination with temozolomide (TMZ) in patients with diffuse gliomas at first relapse (Phase I), and to determine the antitumor effectiveness of the combination of NMS-03305293 and TMZ in patients with isocitrate dehydrogenase (IDH) wild type glioblastoma at first relapse as measured by the 6-month Progression Free Survival (PFS) rate (Phase II). A Study of Molecular Anatomic Imaging Analysis of Tau, the Primary Pathological Protein in Progressive Supranuclear Palsy Rochester, Minn. The purpose of this study is to learn more about the distribution of the pathological protein tau in the living brains of patients with Progressive Supranuclear Palsy (PSP). A Study of Factors That Predispose, Promote, and Perpetuate Post-Traumatic Dizziness Rochester, Minn. The purpose of this study is to investigate whether recent, groundbreaking discoveries about key pathophysiologic processes that drive chronic dizziness in patients without traumatic brain injury (TBI9,10) are applicable to patients with post-mTBI vestibular disability. We expect the results of this project to have practical clinical and research applications, providing novel data for two future steps: A Study to Evaluate Quantitative Phenotypes of Movement Disorders Jacksonville, Fla. The purpose of this study is to determine if adaptive rhythmic auditory stimulation (ARAS) is a safe means of improving gait; i.e., fewer falls, abrupt accelerations/decelerations in patients with movement disorders. Furthermore, we aim to provide patients with a safe environment in which they can safely navigate through an enjoyable experience (guided art tour) that provides exercise, social engagement, and exposure to art. A Study to Evaluate Endoscopic Endonasal Skull Base Surgery and Pituitary Surgery Quality of Life Rochester, Minn. The objectives of this study are to: Measure the short and long-term overall and nasal-specific quality of life (QOL) impact of patients undergoing Endoscopic Endonasal Skull Base Surgery (EESBS) for pituitary and sellar lesions. Determine the relative difference in QOL impact of EESBS for patients undergoing surgery for functional and nonfunctional pituitary adenomas. Generate baseline data to development and validate a site-specific endoscopic-specific comprehensive QOL for EESBS. Particular tumors of interest include pituitary tumors, Rathke’s cleft cysts, craniopharyngiomas, clival chordomas and chondrosarcomas. Specific QOL aims focus on olfaction (sense of smell), gustation (sense of taste) and nasal function. A Long Term Study of Molecular and Structural Imaging in Atypical Alzheimer's Disease Rochester, Minn. The purpose of this study is to learn more about amyloid and tau burden in the brain of patients with Atypical Alzheimer's Disease and how that burden may change over a two-year period. A Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Anti-tumor Activity of WSD0922-FU Scottsdale/Phoenix, Ariz., Jacksonville, Fla., Rochester, Minn. The purpose of this study is to determine the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of WSD0922-FU in subjects with recurrent glioblastoma, IDH wildtype (GBM), anaplastic astrocytoma, IDH wildtype (AA) and CNS metastases of non-small cell lung cancer (NSCLC). A Study to Evaluate Droperidol Use in the Emergency Department and the Effect on QTc Rochester, Minn. The purpose of this study is to study the length of the QTc interval in patients receiving the standard of care dose of intravenous droperidol for headache or migraine, nausea, pain, and indications other than agitation over 30 minutes. A Study to Assess Neuroinflammation in Epileptic Tissue Immediately Prior to Surgical Resection Using Intraoperative Brain Microdialysis Rochester, Minn. The purpose of this study is to measure the space and time characteristics of inflammatory mediator release in response to induced epileptiform activity in ASD-resistant patients.
