1. 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.

2. A Study to Evaluate Advanced Development of Desorption Electrospray Ionization Mass Spectrometry for Intraoperative Molecular Diagnosis of Brain Cancer

   Jacksonville, Fla.

   The purpose of this study is to explore the translational abilities of desorption electrospray ionization mass spectrometry (DESI-MS) as intraoperative diagnostic tool to identify cancerous versus noncancerous tissue and estimate the percentage of tumor infiltration in tissue biopsies, by monitoring depletion of N-acetylaspartate (NAA) and aberrations of the phospholipid signature of neurological tissue; and to identify the presence of IDH mutations by monitoring the 2-hydroxyglutarate (2HG) and, therefore, differentiate between IDH-mutant and wild-type gliomas.

3. A Study to Explore if it is Possible to Successfully Obtain Optical Coherence Tomography (OCT) Imaging and Data While Patients Undergo Brain Surgery

   Jacksonville, Fla.

   The goal of this study is to investigate the feasibility of successfully obtaining intra-operative OCT imaging and data during standard brain surgery.

4. A Study to Evaluate Sex and Gender in Multiple System Atrophy

   Rochester, Minn.

   The primary purpose of this study is to understand the influence of sex and gender on pathophysiologic mechanisms of neurodegeneration in Multiple System Atrophy (MSA) in order to determine sex-specific hormonal factors associated with onset of symptoms in MSA.

5. Peripheral Nerve Stimulation Therapy for Atrial Fibrillation

   Rochester, Minn.

   The purpose of this study is to determine and compare the safety and efficacy of transcutaneous afferent patterned stimulation (TAPS) and respiratory-gated auricular vagal afferent nerve stimulation (RAVANS) therapies for the reduction of paroxysmal atrial fibrillation (AF) burden.

6. A Study of the Possible Use of a New Imaging Method with Glioma Tumors

   Rochester, Minn.

   The purpose of this study is to see if Magnetic Resonance Elastography (MRE) a recently developed imaging technique can be used to characterize and help stage glioma tumors and evaluate response to therapy.

7. Advanced Care Planning in Dementia

   Jacksonville, Fla.

   The goal of this study is to gain a better understanding of the status of advanced care planning among caregivers of patients with dementia and examine how this differs by race and disease stage.

8. Memantine Hydrochloride and Whole-Brain Radiotherapy With or Without Hippocampal Avoidance in Reducing Neurocognitive Decline in Patients With Brain Metastases

   Mankato, Minn., La Crosse, Wis., Eau Claire, Wis., Rochester, Minn., Albert Lea, Minn.

   This randomized phase III trial compares memantine hydrochloride and whole-brain radiotherapy with or without hippocampal avoidance in reducing neurocognitive decline in patients with cancer that has spread from the primary site (place where it started) to the brain. Whole brain radiotherapy (WBRT) is the most common treatment for brain metastasis. Unfortunately, the majority of patients with brain metastases experience cognitive (such as learning and memory) deterioration after WBRT. Memantine hydrochloride may enhance cognitive function by binding to and inhibiting channels of receptors located in the central nervous system. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Using radiation techniques, such as intensity modulated radiotherapy to avoid the hippocampal region during WBRT, may reduce the radiation dose to the hippocampus and help limit the radiation-induced cognitive decline. It is not yet known whether giving memantine hydrochloride and WBRT with or without hippocampal avoidance works better in reducing neurocognitive decline in patients with brain metastases.

9. Multiscale EEG Dynamics

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose if this study  to combine state of the art cerebral signal processing techniques and localization methods with intracranial electrode recordings to investigate the interaction of local hippocampal and neocortical networks with distributed brain activity.

10. A Study to Develop A Family Registry to Collect Alzheimer's Biomarkers

    Jacksonville, Fla.

    The overall purpose of this research is to understand how ADAD develops in order to eventually provide treatments for this disorder. Each biological child of a person with an ADAD mutation has a 50% risk of inheriting the mutation, and thus of developing ADAD. This study will develop a registry of families with a known ADAD mutation and will collect, analyze and bank data, tissue, and brain images from the members who participate in the DIAN research study. The data and tissue collected are available to all qualified researchers who wish to determine what changes occur before and after ADAD symptoms start. This understanding may lead to better tests and treatments for ADAD.
