MSA - Multiple System Atrophy

This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/

This is an open-label, single-center Phase 1 study evaluating the safety, tolerability, and test-retest characteristics of \[11C\]MODAG-005, an investigational positron emission tomography/computed tomography (PET/CT) radioligand intended to image pathological alpha-synuclein deposition in the brain. The study will enroll participants with Parkinson's disease (PD), participants with multiple system atrophy (MSA), and age-matched healthy controls (AMHC). Participants with PD or MSA will undergo two \[11C\]MODAG-005 PET/CT imaging sessions: one baseline scan and one follow-up scan 7 to 48 days later. Age-matched healthy controls will undergo one baseline scan. A subset of PD and MSA participants will receive a single oral dose of anle138b (Emrusolmin) before the second scan to evaluate tracer uptake under blocking conditions. The primary objective is to assess the safety and tolerability of \[11C\]MODAG-005. Secondary objectives include evaluating whether \[11C\]MODAG-005 PET imaging can distinguish participants with MSA or PD from age-matched healthy controls, distinguish PD from MSA, and determine test-retest variability of PET outcome measures.

The aim of this study is to describe national trends over the past 10 years in patients receiving invasive home mechanical ventilation (HMV) in Denmark. This includes indications for invasive HMV, diagnostic groups, and one-year mortality.

The goal of this study is to use ultra-high-resolution (UHR) PET imaging to better understand how the brain and spinal cord change in healthy aging and in neurological and psychiatric disorders such as Alzheimer's disease (AD), Parkinson's disease and related movement disorders, amyotrophic lateral sclerosis (ALS), and psychotic disorders. Researchers will use the NeuroExplorer PET/CT system, a new scanner that can show very small structures in the brain and spinal cord in much more detail than regular PET. The main questions this study aims to answer are: * How do small but important brain regions (like the locus coeruleus, substantia nigra, and thalamic nuclei) change in healthy aging? * What early brain changes occur in neurodegenerative and psychotic disorders, and can they help improve early diagnosis? Participants will: * Undergo PET and MRI brain scans using different tracers that measure brain metabolism (18F-FDG), synaptic density (¹⁸F-SynVesT-1), dopamine transporters (¹⁸F-PE2I), and tau protein buildup (¹⁸F-MK6240). * Complete cognitive and clinical assessments related to memory, mood, and motor or psychiatric symptoms, depending on their group. This study will include healthy volunteers and patients with mild cognitive impairment due to Alzheimer´s disease, ALS, Parkinson's disease and related disorders, or psychotic disorders. The results will help create detailed brain imaging maps for healthy aging and identify early biomarkers for different diseases to support better diagnosis and treatment in the future.

Clinical diagnosis of Parkinson's disease (PD), multiple system atrophy (MSA) and dementia with Lewy bodies (DLB) is challenging, especially in the early stages. Each disease is associated with distinct conformers of misfolded alpha-synuclein (maS) which form typical protein aggregates in the brain and represent key disease biomarkers. Thus, detection and characterization of intracerebral maS aggregates allow a definite diagnosis. The recent development of ultrasensitive assays enabled the detection of maS and other potential new biomarkers in peripheral tissues, although with several limitations. Here, the investigators propose to combine the expertise of leading and young researchers in the field of neurology, structural and molecular biology, biophysics and machine learning to perform ultrasensitive and multi-omics analyses of olfactory mucosa (OM), blood and urine of PD, MSA and DLB patients for detecting and characterizing key peripheral biomarkers allowing accurate disease recognition.

This study investigates the safety and efficacy of autologous stem cell therapy in patients with Multiple System Atrophy (MSA), a rare and progressive neurodegenerative disorder characterized by autonomic failure, parkinsonism, and cerebellar ataxia. The trial will evaluate functional outcomes, motor performance, and quality of life compared to placebo/controlled group.

This study is an observational, prospective genetic study. It aims to obtain DNA for research and testing from patients with PSP, CBS, MSA, and related neurological conditions and their families. Up to 1,000 adults who have been clinically diagnosed with PSP, CBS, MSA, or related neurological conditions will be enrolled. The study intervention involves sequencing of participant blood samples using non-CLIA-approved whole genome sequencing at the National Institutes of Health. Pathogenic variants that are deemed possibly related to these conditions will be confirmed using CLIA-approved testing. The study involves minimal risk to participants.

Study goal: The goal of this prospective head to head comparison is to evaluate the effectiveness of \[18F\]-MFBG PET in assessing cardiac innervation, comparing it with \[123I\]-MIBG SPECT The study's primary focus is on distinguishing between Parkinson's disease (PD) and multiple system atrophy (MSA), as well as between dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). Main questions: * Feasibility: How well can \[18F\]-MFBG PET detect changes in myocardial uptake in PD and DLB compared to the expected normal values in healthy individuals and AD and MSA-P patients? How well can it differentiate between these groups based on the detected changes? * Non-inferiority: Is \[18F\]-MFBG PET as accurate as \[123I\]-MIBG SPECT in distinguishing between PD and MSA-P, and between DLB and AD? Participant requirements: For the main study, participants will be required to visit the hospital for 3 or 4 appointments. During these visits, they will undergo a screening visit, MRI brain scan, a comprehensive neurological assessment, \[18F\]-PE2I PET, \[123I\]-MIBG SPECT, and \[18F\]-MFBG PET scans. Additionally, a separate dosimetry study will be conducted, involving healthy subjects who will visit the hospital for a screening visit and undergo \[18F\]-MFBG PET scans.

We are trying to identify factors associated with improved quality of life and fewer PD symptoms. We are attempting to identify practices, beliefs, and therapies used by individuals who report excellent quality of life, few PD symptoms, and reduced rates of progression. After agreeing to participate, we will ask participants to fill our questionnaires about their experience with PD, their health in general, along with their food intake every six months for five years.
