1. A Study to Evaluate Traditional Versus Early Aggressive Therapy for Multiple Sclerosis Patients

   Rochester, Minn.

   The purpose of this study is to evaluate, jointly and independently among patients deemed at higher risk vs. lower risk for disability accumulation, whether an "early aggressive" therapy approach, versus starting with a traditional, first-line therapy, influences the intermediate-term risk of disability, and to evaluate if, among patients deemed at lower risk for disability who start on first-line MS therapies but experience breakthrough disease, those who switch to a higher-efficacy versus a new first-line therapy have different intermediate-term risk of disability.FDA-approved multiple sclerosis (MS) disease-modifying therapies (DMTs) target the relapsing phase of MS but have minimal impact once the progressive phase has begun. It is unclear if, in the relapsing phase, there is an advantage of early aggressive therapy with respect to preventing long-term disability. The infectious risks and other complications associated with higher-efficacy treatments highlight the need to quantify their effectiveness in preventing disability. The TRaditional versus Early Aggressive Therapy for MS (TREAT-MS) trial is a pragmatic, randomized controlled trial that has two primary aims:

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. 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.

4. 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.

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 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. 

7. 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:

8. 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.

9. A Study to Evaluate Pluripotent Stem Cell Models for Spinal Muscular Atrophy (SMA) Patients

   Rochester, Minn., La Crosse, Wis., Jacksonville, Fla.

   The purpose of this study is to perform RNA sequencing on induced pluripotent stem cells (iPSC).  By comparing the gene expression of motor neurons derived from iPSC cells of phenotypically discordant Spinal Muscular Atrophy (SMA) sibling pairs and individual cases of SMA, we hope to identify potential protective gene modifiers of SMA.   Identifying protective gene modifiers will increase our understanding of the molecular pathogenesis of SMA.

10. Synucleinopathies

    Rochester, Minn.

    The goals of the study are to prospectively evaluate clinical and laboratory biomarkers of multiple system atrophy and Parkinson’s disease at early clinical disease, at a premotor stage (PAF), and even at a prodromal stage (RBD).
