Active clinical trials for "Neurodegenerative Diseases"

Explore the effects of natural plant flavonoids on the positive intervention mechanism of neurotransmitter transmission physiological indicators changes (EEG) in the brain of the study subjects; Investigate the effects of natural plant flavonoids in positively intervening clinical symptoms of the study subjects.

The purpose of this protocol is to create an active natural history cohort of patients with degenerative movement disorders, tracked in a clinical setting with clinical rating scales and neuroimaging. The overarching rationale is that neurodegenerative diseases may be heterogeneous, complex disorders. A new way of performing clinical trials in these patients may be in order and this protocol aims to build a longitudinally tracked clinical trial-ready cohort of patients. The purpose of this protocol is to establish an active natural history cohort of patients with neurodegenerative movement disorders who are deeply phenotyped and "clinical trial ready" across Mass General Brigham. After a thorough clinical diagnostic evaluation (this may include clinically indicated testing, for example MRI, FDG-PET, MIBG scan, polysomnography, genetic testing, autonomic function tests, inflammatory tests, skin biopsy) the investigators aim to achieve this through: Longitudinal tracking of clinical progression through use of clinical scales including at the present time: UMSARS, BARS, MoCA and UPSIT, PROM, MDS-NMS, UPDRS, and SARA Longitudinal tracking of disease progression through use of neuroimaging including at the present time: TSPO-PET and 3D MRI (see section 1.3) This is a pilot study designed to track patients with neurodegenerative movement disorders across Mass General Brigham through MRI and PET imaging modalities and clinical measures. Figure 5 represents the study design in detail. In short, subjects will be asked to visit Mass General Brigham every 6-9 months over the course of 18 months for imaging and clinical evaluation.

The purpose of the study is to systematically characterize the clinical course of the progressive neuropathy and optic atrophy observe in pediatric and adult patients with biallelic mutations in the solute carrier family 25 member 46 (SLC25A46) gene.

Currently, the Movement Disorders Society (MDS)-UPDRS scale remains the gold standard to document the outcomes in clinical trials for Parkinson's disease (PD). The MDS-UPDRS is far from infallible, as it is based on subjective scoring (using a rather crude ordinal score), while execution of the tests depends on clinical experience. Not surprisingly, the scale is subject to both significant intra- and inter-rater variability that are sufficiently large to mask an underlying true difference between an effective intervention and placebo. Digital biomarkers may be able to overcome the limitations of the MDS-UPDRS, as they continuously collects real-time data, during the patient's day to day activities. In this study the investigators are interested in developing algorithms to track progression of bradykinesia, gait impairment, postural sway, tremor, physical activity, sleep quality, and autonomic dysfunction (the latter being derived from e.g. skin conductance and changes in heart rate variability).

Alzheimer´s disease (AD) in one of the most important causes of dementia and poses a considerable challenge in health care. Today, criteria for the diagnosis and the follow up of patients with AD mainly rely either on subjective tests or invasive methods. This limits the general applicability of the latter test for population screening and underlines the need for the identification of easily accessible tools for the identification of high-risk subjects. Because of its unique optical properties, the eye offers the possibility of the non-invasive assessment of both structural and functional alterations in neuronal tissue. As the neuro-retina is part of the brain, it does not come as a surprise that neuro-degenerative changes in the brain are accompanied by structural and possibly also functional changes in the neuro-retina and the ocular vasculature. The current study seeks to test the hypothesis that beside the known anatomical changes, also functional changes can be detected in the retina of patients with AD. For this purpose, flicker light induced hyperemia will be measured in the retina as a functional test to assess the coupling between neural activity and blood flow. Further, structural parameters such as retinal nerve fiber layer thickness and function parameters such as ocular blood flow and retinal oxygenation will be assessed and compared to age and sex matched controls.

This multicenter natural history study aims to expand the network of clinical research centers in FA, and to provide a framework for facilitating therapeutic interventions. In addition, this study will lead to the development of valid yet sensitive clinical measures crucial to outcome assessment of patients with Friedreich's Ataxia. This study will support genetic modifier studies, biomarker studies, and frataxin protein level assessments by building a sample repository.

"Brain-computer interfaces (BCIs) are computer-based systems that acquire brain signals, analyze them, and translate them into commands that are relayed to an output device to carry out a desired action. BCIs represent a very active and promising field of research among devices for people with severe motor disabilities. As the currently available systems correspond to research prototypes, they are not adapted to daily live situations. On the other hand, some systems have recently been commercialized, principally for video games but they are not satisfactory for use as a substitute technology in disability. A BCI's prototype for alternative communication using a virtual keyboard, the P300 Speller, has been developed by the National Institute for Research in Digital Science and Technology (Athena team - Nice University). This prototype includes an EEG-cap with gel based active electrodes. A recent study conducted on 20 patients with ALS (University Hospital, Nice) demonstrated the usability of the system and the patient satisfaction concerning the ease of use and utility. To achieve a system that can be used in daily live in severely disabled patients, technical developments are necessary. The investigators have conceptualized and developed an ergonomic, comfortable, headset, including dry electrodes to allow a prolonged use of the system. The purpose of the study conducted all along the development of the headset is to improve the developed system until a successful system is achieved. This study is a monocentric usability study conducted on ALS people.

This project aims to create a digital platform for personal, clinical, diagnostic and environmental data collection, management and analysis of patients with cardiovascular and neurological disease or cancer admitted to the Neuromed Group clinics, associated with a biobanks of biological fluids and human tissues and a biotechnological platform for "omics" analysis, to encourage personalized, preventative and predictive care.

This grant award entitled, "Cerebrovascular Reactivity and Oxygen Metabolism as Markers for Neurodegeneration after Traumatic Brain Injury" (hereafter, "Neurovascular Study"), aims to determine if neurovascular contributors to neurodegeneration can serve as markers of the emergence or progression of degenerative processes after traumatic brain injury in middle-aged and older adults.

With the increase in life expectancy of our population due to advancement of medical diagnosis and treatments, the incidence of age dependent neurodegenerative diseases increased, including Alzheimer's disease (AD), parkinsonian syndromes (PS), small vessel disease (SVD) and motor neuron disease (MND). In spite of the progress of knowing the pathogenesis of various neurodegenerative diseases at molecular and genetic level, they are still very incompletely understood and often cause diagnostic and therapeutic challenges to physicians. Due to the overlapping presentation and similar brain pathology, especially in the early stage of the diseases, it is difficult to differentiate idiopathic Parkinson's disease (iPD) from atypical parkinsonian syndromes, such as multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). Similarly, distinguishing AD from other dementia syndromes including frontotemporal dementia (FTD), dementia with Lewy Bodies (DLB), corticobasal degeneration (CBD) and vascular dementia can be difficult. It is necessary to develop accurate and comprehensive diagnostic tests to properly prognosticate the diseases, start treatments in early stage of the diseases and maximize the accuracy of drug trials for more effective preventive and therapeutic measures for these neurodegenerative diseases. Therefore, the registry aims to generate a large database of cognitive, behavioral, lifestyle and psychological information of the subjects who suffered from neurodegenerative diseases, as well as to examine the genetic basis of neurodegenerative diseases to help decode the pathogenic mechanisms of the diseases. The registry may provide important information to understand symptom development of the neurodegenerative diseases, in which may help physicians to diagnose the diseases more accurately and provide better treatment plans.
