PLS Natural History Study Rochester, Minn., Jacksonville, Fla. The purpose of this study is to develop a natural history dataset and biorepository of early Primary Lateral Sclerosis (PLS) and well-established PLS cases for future clinical trials. Extracellular Impact Of Ultrasound-induced Blood-brain Barrier Disruption Rochester, Minn. The purpose of this study is to determine the impact of focused ultrasound (FUS) on the composition of the tumor extracellular microenvironment. Investigating The Genetic And Phenotypic Presentation Of Ataxia And Nucleotide Repeat Diseases Scottsdale/Phoenix, Ariz., Jacksonville, Fla. The purpose of this study is to create a repository for cerebellar ataxia and nucleotide repeat diseases in order to fully investigate the genetic and phenotypic presentations of both. A Study Of Sonodynamic Therapy With SONALA-001 And Exablate 4000 Type 2.0 In Subjects With Progressive Or Recurrent Glioblastoma Multiforme (RGBM) Rochester, Minn. The purpose of this study is to characterize the safety, dose limiting toxicities (DLTs), maximum tolerated dose (MTD), maximum administered dose (MAD) and recommended phase 2 dose (RP2D) for future study after treatment with SONALA-001 in combination with MRgFUS in subjects with progressive or rGBM. Droxidopa / Pyridostigmine In Orthostatic Hypotension Rochester, Minn. The hypothesis is that pyridostigmine will improve the safety factor of ganglionic neural transmission, while Droxidopa will replete the postganglionic neuron of norepinephrine (NE). This combination should result in enhanced orthostatic release of NE. The investigators have already demonstrated that pyridostigmine does not raise supine blood pressure. A Study To Establish A Parkinson’s Disease (PD) Cohort Using The Parkinson’s Progression Markers Initiative (PPMI) Scottsdale/Phoenix, Ariz. The Parkinson Progression Marker Initiative (PPMI) is a study to assess progression of clinical features, digital outcomes, and imaging, biologic and genetic markers of Parkinson’s disease (PD) progression in study participants with manifest PD, prodromal PD, and healthy controls. The overall goal of PPMI is to identify markers of disease progression for use in clinical trials of therapies to reduce progression of PD disability. Primary Tumor Research And Outcome Network (PTRON) Registry Rochester, Minn. The purpose of this registry is to collect clinical, diagnostic, and therapeutic data specific for primary spinal column tumor patients, and evaluate it to understand the predictive factors which influence survival, local recurrence, adverse events, perioperative morbidity, and health related quality of life. Human Blood and Tissues Repository for Neuroscience Research Jacksonville, Fla. The purpose of this study is to collect adult human blood, cerebrospinal fluid, brain, and spine tissues/fluids at time of surgery in order to conduct future studies of the cellular mechanisms of tissue invasion utilized by brain and spine tumors of the central nervous system (CNS). Magnetic Resonance Elastography of Dementia Rochester, Minn. The purpose of this study is to develop and test the effectiveness of an investigational imaging technique called magnetic resonance elastography (MRE) to measure the stiffness (mechanical properties) of tissues. Arizona Alzheimer’s Disease Research Center (ADRC-001) Scottsdale/Phoenix, Ariz. There is evidence that neurodegenerative changes precede clinical symptoms in Alzheimer’s disease by two decades (Villemagne et al, 2013). Early detection is critical for development of interventions to halt, slow, or even reverse these pathological processes. The promise of plasma biomarkers to identify early pathology is growing rapidly (Palmqvist et al, 2020), however it is likely that multiple converging biomarkers will be necessary to identify the earliest pathological changes, as subtle differences from healthy controls may fall within the margin of error for any given single biomarker measure. Here we propose that the evaluation of speech and language for both baseline (cross-sectional) and longitudinal changes (within-participant) may add significant value to early pre-clinical pathological changes in MCI and AD. This is bolstered by emerging evidence of the relationship between language characteristics and amyloid burden (Verfaillie et al, 2019) and the large literature that characterizes language-use differences and deficits across the spectrum of cognitive decline (e.g., Mueller et al, 2018). We propose to add a series of in-clinic language elicitation tasks that allow for automated assessment of relevant speech and language domains and to validate these measures cross-sectionally and longitudinally relevant to neuropsychological, blood, and PET biomarkers. التصفّح دراسات سريرية السابقالصفحة السابقة توجّه للصفحة 22 توجّه للصفحة 33 توجّه للصفحة 44 توجّه للصفحة 55 توجّه للصفحة 66 التاليالصفحة التالية المتخصصون في المجالات الطبية Neurology & Neurosurgery clinical-trials
