Filter by:This study evaluate the interest to create a new database of PET digital brain exams in population of 50 years and over of patients. Half of patients with no abnormal brain metabolism while the other half patients with Alzheimer's disease.
The Ontario Neurodegenerative Disease Research Initiative (ONDRI) is a province-wide collaboration studying dementia and how to improve the diagnosis and treatment of neurodegenerative diseases including: - Alzheimer's disease (AD) - Parkinson's disease (PD) - amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease) - frontotemporal lobar degeneration (FTD) - vascular cognitive impairment, resulting from stroke (VCI)
This will be a Phase 1, open label, imaging study of radiochemical and radiation safety in healthy volunteers. Using positron emission tomography (PET) and in-line computed tomography (CT), the whole body (WB) biokinetics of Carbon-11 butanol will be quantified with serial scans acquired every 3 minutes for two hours. Vital signs (VS), electrocardiograms (ECGs) and clinical laboratory tests of intrernal organ function will be acquired before and at several timepoints after administration of the radiopharmaceutical. Radiation exposures will be estimated with the MIRD Formalism.
Elegible patients were included in the study and underwent treatment with a solution of citicoline 1% eye-drops, 0.2% high molecular weight hyaluronic acid and 0.01% benzalkonium chloride prior to surgery. The vitreous samples were taken at the beginning of the surgery and analyzed for qualitative/quantitative determination of vitreous concentration of citicoline and its metabolites by means of high performance liquid chromatography.
Alzheimer's disease (AD) is the most common cause of dementia and currently has no disease modifying treatments or simple accurate diagnostic tests. The goal of this project is to study how tau (a protein thought to cause AD) is made, transported and cleared in the human body. Better understanding of these processes may lead to improved understanding of AD, earlier diagnosis and a way to evaluate treatment.
Parkinson disease (PD) is a chronic degenerative disease characterized by a progressive loss of dopaminergic neurons in the substantia nigra. Its pathophysiological mechanisms are still partially unknown; a main role seems to be played by chronic neuroinflammation. A few reports have addressed the possible involvement of the inflammasome in PD, just describing the protective effect of P2X7 purinergic receptor (P2X7R) blockers in murine models of the disease and in microglial cells, where NLRP3 is activated by α-Synuclein, triggering a neuroinflammation that contributes to degeneration of dopaminergic neurons. It is still unclear whether, in addition to the increased brain expression and function of the nucleotide-binding domain, leucine-rich repeat, pyrin domain containing type 3 (NLRP3) inflammasome platform, a systemic activation of such complex might participate in the pathogenesis of PD, which could be the role of the P2X7R in this scenario, and whether such patterns undergo any specific epigenetic regulation. The present study has been designed to address these issues.
1. Primary objective: Determine if NR has an impact on the neurometabolic profile of patients with PD as measured by [18F]Fluorodeoxyglucose (FDG)-positron emission tomography (FDG-PET). 2. Secondary objective: Determine whether high dose oral NR improves motor symptoms associated with PD. 3. Tertiary objectives: determine whether high dose oral NR rectifies NAD metabolism and increases NAD levels in body fluids and muscle tissue.
This study is an extension to the HP-CD-CL-2002 clinical study. It evaluates the long-term safety and tolerability of CDNF in patients with Parkinson's disease when dosed directly into the brain using an implanted investigational drug delivery system (DDS). Long-term safety of the DDS is also being evaluated. All patients will receive monthly infusions of either mid- or high-dose of CDNF for a period of 6 months.
Rural patients with life-limiting illness are at very high risk of not receiving appropriate care due to a lack of health professionals, long distances to treatment centers, and limited palliative care (PC) clinical expertise. Secondly, although culture strongly influences people's response to diagnosis, illness and treatment preferences, culturally-based care models are not currently available for most seriously-ill rural patients and their family caregivers. Lack of sensitivity to cultural differences may compromise PC for minority patients. The purpose of this study is to compare a culturally-based Tele-consult program to usual hospital care to determine whether a culturally-based PC Tele-consult program leads to lower symptom burden in hospitalized African American and White older adults with a life-limiting illness.
The purpose of this study is to evaluate the long-term safety and tolerability of pimavanserin in adult and elderly subjects with neuropsychiatric symptoms related to neurodegenerative disease exposed to open-label pimavanserin for up to 52 weeks.
