1. A Study to Evaluate Caregiver Connections via Technology for Patients with Alzheimer's and Other Types of Dementia

   Rochester, Minn.

   The purpose of this study is to optimize profile questionnaire and matching algorithm developed in Phase I and implement in final website design, and to determine if algorithmically matched participants have statistically significant increase in match satisfaction and self-reported sense of resiliency and quality of life over randomly matched caregivers.

2. Submandibular Gland Needle Core Biopsy and Skin Punch Biopsy as Tissue Biomarkers for the Diagnosis and Monitoring of Disease Progression of Parkinson’s Disease and REM Sleep Behavior Disorder

   Scottsdale/Phoenix, Ariz.

   Determine 1) the magnitude of SMG and skin a-syn density change over time, 2) the

   improvement in adequate tissue acquisition doing bilateral SMG biopsies, 3) any laterality differences between

   SMG gland a-syn density, 4) correlate a-syn density and changes in density between SMG and skin biopsies

   Specific Aim 1. Determine, with bilateral submandibular gland (SMG) biopsies in 30 clinically

   diagnosed subjects with Parkinson’s disease (PD) and 20 clinically probable REM sleep behavior

   disorder (RBD) subjects whether bilateral biopsies improve the rate of acquisition of adequate

   glandular tissue, whether alpha-synuclein (a-syn) SMG pathology correlates with clinical severity

   and/or disease duration, and whether there is a left-right difference in the density of a-syn pathology.

   Specific Aim 2. Determine, with a second SMG biopsy in previously biopsied PD and RBD subjects,

   whether a-syn pathology density increases, decreases, or remains the same after a 1.5-2 year time

   interval and whether there is a correlation between a-syn SMG pathology and clinical and/or disease

   progression.

   Specific Aim 3. Determine whether a-syn pathology density in skin punch biopsies correlates

   with clinical measures and increases, decreases, or remains the same after a 1.5-2 year time

   interval, and whether the density and changes over time correlate with those found in SMG

   biopsies.

3. Reduced Craniospinal Radiation Therapy and Chemotherapy in Treating Younger Patients With Newly Diagnosed WNT-Driven Medulloblastoma

   Rochester, Minn.

   This phase II trial studies how well reduced doses of radiation therapy to the brain and spine (craniospinal) and chemotherapy work in treating patients with newly diagnosed type of brain tumor called WNT)/Wingless (WNT)-driven medulloblastoma. Recent studies using chemotherapy and radiation therapy have been shown to be effective in treating patients with WNT-driven medulloblastoma. However, there is a concern about the late side effects of treatment, such as learning difficulties, lower amounts of hormones, or other problems in performing daily activities. Radiotherapy uses high-energy radiation from x-rays to kill cancer cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, vincristine sulfate, cyclophosphamide and lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving reduced craniospinal radiation therapy and chemotherapy may kill tumor cells and may also reduce the late side effects of treatment.

4. A Study of Pyridostigmine in Postural Tachycardia Syndrome

   Rochester, Minn.

   This is a 3-day study comparing pyridostigmine versus placebo in the treatment of postural tachycardia syndrome (POTS). The researchers expect pyridostigmine to improve tachycardia and stabilize blood pressure.

5. Immune Phenotyping in Amyotrophic Lateral Sclerosis

   Rochester, Minn.

   The goals of this study are to identify biomarkers that allow improved staging or prognosis of the disease, and through the discovery of previously unrecognized immune abnormalities in ALS we aim to eventually identify immune therapies that may provide benefit in ALS.

6. A Study to Evaluate a Color Test for Patients with Optic Nerve Diseases

   Rochester, Minn.

   The purpose of this study is to evaluate the clinical utility of a quantitative test to measure how color saturation appears in patients with diseases of the optive nerve.

7. A Study of Nervous System Involvement of Coccidioidomycosis at Mayo Clinic Hospital in Arizona

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to gain a better understanding of the presentation, diagnostics, disease course and treatment variations, as well as the factors that may influence features of neuro-invasive Coccidioidomycosis. 

8. A Study to Evaluate Sex Differences in Multiple Sclerosis Spectrum of Demyelinating Disorders

   Rochester, Minn.

   The purposes of this study are to explore the association between female sex, reproductive history and clinical phenotypic variability in multiple sclerosis (MS), to explore the association between female sex, reproductive history and radiologic phenotypic variability in MS, and to explore the association between female sex, genetic and environmental interactions in MS.

    

9. 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).

10. A Study of the Role Connective Tissue and Wound Healing Characteristics Play in Patients with Multiple Brain Aneurysms

    Rochester, Minn.

    The purpose of this study is to develop an increased understanding of the role of connective tissue structural abnormalities and impaired function (i.e. wound healing) in the development of intracranial aneurysms.
