A Study to Assess Changes in Clinical Management After DaTSCAN Imaging of Subjects With Clinically...
Parkinsonian SyndromesPatients come to their doctor showing possible symptoms of a movement disorder. It is possible that these symptoms may get worse over time. There is more than one disease that can cause such symptoms. The most common movement disorder illnesses are Parkinson´s Disease and Essential Tremor. Sometimes it is difficult for doctors to make the right diagnosis because the symptoms caused by these illnesses are almost the same. On the other hand the correct treatment for Parkinson´s Disease is different from the correct treatment for Essential Tremor. This study aims to see whether having pictures of the brain taken with DaTSCAN can affect the way the doctor treats these patients and whether it can affect their quality of life directly.
To Study the Efficacy of Bromocriptine in Patients With Hepatic/Cirrhosis Related Parkinsonism
Cirrhosis Related ParkinsonismAfter successful screening of liver cirrhosis patients attending ILBS OPD for signs of parkinsonism ( tremor, rigidity or bradykinesia, any 2 of 3). Diagnosis of hepatic/cirrhosis related parkinsonism will be made. Patients will be randomized into Bromocriptine and Placebo. Patients will be followed up every month in OPD (Out Patient Department), ILBS (Institute of liver & Biliary Sciences) for 3 months. Detailed neurological examination will be done at each visit & UPDRS (Unified Parkinson's Disease Rating Scale ) score will be calculated.
A Study to Evaluate the Diagnostic Efficacy of DaTSCAN™ Ioflupane (123I) Injection in Single Photon...
Parkinsonian SyndromeParkinson Disease(PD)3 moreThis is a multicenter, open-label, non-controlled, non-randomized, phase 3 clinical study to compare the SPECT findings after a single IV administration of DaTSCAN™ ioflupane (123I) injection for patients with a clinical diagnosis of Parkinsonian syndrome (PS) involving striatal dopaminergic deficit (SDD; specifically, Parkinson's disease [PD] [SDD], multiple system atrophy [MSA] [SDD] or or progressive supranuclear palsy [PSP] [SDD]) as compared with patients with a clinical diagnosis of essential tremor (ET) (no SDD) and age-matched healthy controls.
A Trial of 18F-AV-133 Positron Emission Tomography (PET) Imaging to Differentiate Subjects With...
Parkinson's DiseasePrimary Parkinsonism1 moreThe purpose of this study is to determine whether 18F-AV-133 PET scans can be used to differentiate subjects with Parkinson's Disease from other movement disorders.
Low Dose Apomorphine and Parkinsonism
Parkinson's DiseaseThe purpose of this study is to determine if low doses of apomorphine worsen the motor symptoms of Parkinson's disease.
18F-DTBZ PET and Multi-modal MRI in the Patients With Vascular Parkinsonism
Vascular ParkinsonismForty patients with clinically diagnosed VP and 20 healthy subjects will be enrolled in the study. Each evaluable subject involved in this study must fulfill all the inclusion and exclusion criteria and each subject will have 3 visits in the study, as one screening visit, one imaging visit, and one safety evaluation visit.
The Differential Diagnosis of Parkinson's Disease and Parkinsonism by Positron-emission Tomography...
Parkinson's DiseaseThe objective of this protocol is to analyze the sensitivity and specificity of 18F-DTBZ PET to the differential diagnosis of Parkinson's disease (PD) and other parkinsonism disorders, including multiple system atrophy (MSA), corticobasal degeneration (CBD), and progressive supranuclear palsy (PSP).
Incobotulinum Toxin A for Sialorrhea in Parkinson's Disease (PD)/Parkinsonism and Amyotrophic Lateral...
Parkinson DiseaseAmyotrophic Lateral SclerosisThe purpose of this study is to evaluate the safety and efficacy of Incobotulinum Toxin A (Xeomin®) injections into the parotid and submandibular glands in patients with Parkinson's Disease/Parkinsonism and Amyotrophic Lateral Sclerosis (ALS) with troublesome sialorrhea.
Development of Imaging, Clinical and Biochemical Bio-Markers for Parkinson's Disease
Parkinson's DiseaseParkinsonian SyndromeWe propose to build on preliminary data evaluating non-dopaminergic/non-motor clinical biomarkers to more fully assess these markers at the threshold of Parkinson disease (PD). Development of reliable biomarkers for both dopaminergic and non-dopaminergic manifestations of Parkinson disease (PD) and related disorders may dramatically accelerate research on PD etiology, pathophysiology, and therapeutics. Biomarkers are broadly defined as characteristics that are objectively measured and evaluated as indicators of normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. Specific biomarkers may be useful at the onset of neurodegeneration, the onset of disease, and/or to mark disease progression.
Imaging and Genetic Biomarkers of Parkinson Disease (PD) Onset and Progression in High-risk Families...
Parkinson DiseaseParkinsonian SyndromeParkinson's disease (PD) is a progressive neurodegenerative disorder characterized by rigidity, bradykinesia, postural instability, and tremor. Clinical decline reflects ongoing degeneration of dopamine-containing neurons. A critical unmet need for clinical research is to improve early detection of these diseases by developing tools to assist with earlier diagnosis. Biomarkers are broadly defined as characteristics that are objectively measured and evaluated as indicators of normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention (Biomarkers Defintions Working Group 2001). Development of reliable biomarkers for PD would dramatically accelerate research on PD etiology, pathophysiology, disease progression and therapeutics. Specific biomarkers may be useful at the onset of neurodegeneration, the onset of disease, and/or to mark disease progression. The biomarkers in this study include brain imaging with a radioactively labelled drug (Beta-CIT), computerized testing of memory, attention, motor speed, judgment and handwriting, and assessments of speech and smell. Subjects may also be asked to provide a blood sample for genetic and biochemical testing.
