Active clinical trials for "Parkinson Disease"

Background: Parkinsons disease (PD) causes slow movement, stiffness, and poor balance. Many symptoms are due to the loss of brain cells that make the brain chemical dopamine. The cells may be damaged by the breakdown of dopamine by a process called oxidation. The drug N-acetylcysteine (NAC) can act as an antioxidant. Researchers want to test if NAC can decrease the oxidation of brain dopamine in people with PD. Objective: To look at the effect of NAC on brain chemistry in people with PD. Eligibility: People ages 18 and older with PD that were diagnosed within the past 5 years. They must be taking a monoamine oxidase inhibitor. Healthy volunteer participants ages 18 and older. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Participants will be hospitalized for 4 to 8 days. On day 1, participants will have blood and urine tests. For several hours, they cannot eat or drink anything but water and their medications. Late in the morning they will have a meal. About 2 hours later they will have a spinal tap (lumbar puncture). For this, a numbing medicine is injected into the back. A needle is inserted between the bones in the back to remove a small amount of fluid. The spinal tap may use x-rays to see inside the body. After the spinal tap, they will start taking NAC by mouth. They will take NAC twice a day for 2 more days. On the next day, they will not eat until a meal in the late morning. They will take a final NAC dose. About 2 hours later they will have a second spinal tap. Healthy Volunteer (HV) participants will receive a spinal tap on day one, followed by a second spinal tap 48 hours after the first spinal tap. HV participants will not receive NAC.

The purpose of this study is to provide proof-of-concept that directional stimulation and directional recording, in an intraoperative setting, is perceivable in a subject. The tests will be performed using a dedicated intraoperative lead connected to an external neuro-recorder/stimulator, during a deep brain stimulation implantation surgery.

The Recreation Therapy Wellness Recovery Program conducts group classes which provide repetitive training of foundational skills designed specifically for those with Parkinson's Disease. The course will encourage bigger and faster movements (adapted from the Parkinson Wellness Recovery, PWR!Moves ® program) and education on optimal function.

This is a study of safinamide, an investigational drug for Parkinson disease (PD). Safinamide is being developed as add-on therapy for the treatment of Parkinson disease. It is theorized that safinamide acts by increasing the available dopamine in those areas of the brain where dopamine is decreased as a result of Parkinson;s Disease. . Dopamine in the brain is involved in controlling body movements. Safinamide has been extensively studied in animals, and has been shown to increase the level of dopamine in these animals. Safinamide has also been tested in patients with Parkinson disease. The goal of this research trial is to see if safinamide is safe and well tolerated and to better understand how it affects the dopamine system in the brain in individuals with Parkinson disease. Data from this trial may provide essential information about the effectiveness and safety of these doses of safinamide in patients with early Parkinson disease, who are already receiving a stable dose of their normal Parkinson disease treatment.

Based on Parkinson's disease (PD)/vitamin B12 deficiency symptom overlap and PD patients' propensity to avoid protein (the dietary source of vitamin B12), this study proposes to prospectively investigate the vitamin B12 status of PD patients over time. In addition, this study will provide critical pilot data evaluating the efficacy of treating those patients considered to have below-normal vitamin B12 levels in serum. Further, it will also explore the concept that supplementing PD patients having "low-normal" vitamin B12 levels with vitamin B12 improves either the non-motor PD symptoms or homocysteine levels in PD patients receiving levodopa. Study Hypotheses: Serum cobalamin (B12) concentrations in patients with Parkinson's disease (PD) are significantly lower than B12 concentrations in a) cohabiting spousal caregiver controls; and b) population-based, age-matched controls. Supplementation with B12 in levodopa-treated PD patients with low (<200 pg/ml) or low-normal (200-300 pg/ml) serum B12 levels is associated with significant improvement in their non-motor symptoms and reduces total plasma homocysteine concentration [Hcy], a known biomarker for risk of dementia and cerebrovascular disease.

The study consists of the realization of a new esophageal stimulation for patients already stimulated 10 years ago. The investigators would like to make a long term evaluation of the evolution of anterograde effective refractory period of accessory duct in the WPW syndrome. This study will be realized by esophageal stimulation.

The main purpose of In two kinds of fasting and postprandial Chinese healthy subjects with Boehringer represent Ingelheim company production of hydrochloric acid Pramipexole zyban (specification: 0.26 mg/piece, in Pramipexole, commodity name: Siforl ®) as the reference preparation, study a single oral dose of macro crown biological pharmaceutical co., LTD. Production of Pramipexole Dihydrochloride Sustained Release Tablets (specification:The pharmacokinetic parameters of the drug were calculated after the time course of the drug in vivo (0.375mg/ tablet, as measured by pramipexole hydrochloride), and the human relative bioavailability of the two preparations were compared to evaluate their bioequivalence. A secondary purpose To evaluate the safety of fasting and postprandial oral test preparations and reference preparations.

This study will focus on patients with Parkinson's Disease in the adult inpatient units of Hackensack University Medical Center. We are measuring the effect of a Parkinson's Disease Inpatient Clinical Knowledge and Management Program on adherence to Parkinson's Disease medication using a Parkinson's Disease Identification Wrist Band, smartwatch and medication schedule card

The study is designed to assess the long term tolerability of ProSavin and whether it is safe and efficacious in patients administered ProSavin from the PS1/001/07 study .

To compare the electrical activity of SubThalamic Nuclei (STN), by mean of local field potentials recordings, during the phasic behaviours of RBD with the electrical activity recorded at this level during the execution of voluntary movements during the "off" and the "on" phases in patients with RBD secondary to PD.
