Active clinical trials for "Parkinson Disease"

Parkinson's disease (PD) is a neurological condition, which affects the brain. PD gets worse over time, but how quickly it progresses varies a lot from person to person. Some symptoms of PD are tremors, stiffness, and slowness of movement. This study measures the efficacy, safety, and tolerability of ABBV-951 versus oral Levodopa (LD)/Carbidopa (CD) [LD/CD] in advanced PD participants to achieve reduction in motor fluctuations. ABBV-951 is an investigational (unapproved) drug containing Levodopa Phosphate/Carbidopa Phosphate (LDP/CDP) given subcutaneously (under the skin) for the treatment of Parkinson's Disease. Adult participants with advanced PD will be enrolled. Approximately 130 participants will be enrolled in the study in approximately 80 sites across the world. In one arm, participants will receive ABBV-951 solution as a continuous infusion under the skin plus oral placebo capsules for LD/CD. In the second arm, participants will receive placebo solution for ABBV-951 as a continuous infusion under the skin plus oral capsules containing LD/CD tablets. The treatment duration is 12 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects, and completing questionnaires.

The purpose is to evaluate feasibility and efficacy of Remote Ischemic Conditioning(RIC) as adjuvant therapy for Parkinson's Disease(PD). Sixty patients will be randomized into 2groups: RIC group receiving Remote Ischemic Conditioning except conventional therapy（n=30）and control group with conventional therapy (n=30).

It is hoped that TAK-071 will help people with Parkinson's disease to walk with better balance. The main aim of the study is to check if there is a difference in how participants walk after treatment with TAK-071. Another aim is to see if it improves how participants think and remember. At the first visit, the study doctor will check who can take part. Participants who can take part will be picked for 1 of 2 groups by chance. Both groups will have 2 treatments but in a different order. The treatments are TAK-071 tablets or placebo. In this study, a placebo will look like the TAK-071 but will not have any medicine in it. One group will take TAK-071 for 6 weeks, have at least a 3-week break, then take a placebo for 6 weeks. The other group will take a placebo for 6 weeks, have at least a 3-week break, then take TAK-071 for 6 weeks. The participants will not know the order of their 2 treatments, nor will their study doctors. This is to help make sure the results are more reliable. The participants will visit the clinic at the beginning and end of each treatment for a check-up. 14 days after the 2nd treatment, clinic staff will telephone the participants for a final check-up.

With an appropriate oral dose of Varenicline (VCN) identified from experiments 1 & 2 of the study (see NCT02933372), the investigators will administer VCN to Parkinson Disease (PD) participants to determine if VCN improves walking speed and measures of balance. PD participants will receive VCN or a placebo (fake drug) for 3 weeks to assess the effects of VCN administration on gait speed and balance. Participants will undergo examinations to assess the intensity of their Parkinsonism and asked questions to assess their mood and thinking.

The purpose of this study is to evaluate the safety and efficacy of stereotactic transplantation of hAESCs for Parkinson's disease.

The efficacy and safety of rotigotine in the treatment of patients with early stage of primary Parkinson's disease

Many studies showed that clinical pilates exercises has positive effects on static and dynamic balance of different populations. It was suggested that this type of exercise reduce the risk of falls and physical damage. It also helps prevention of kyphotic posture. Parkinson's patients have both balance and postural problems but no study investigated the effect of clinical pilates exercises for this population. The aim of this study is to investigate the effects of clinical pilates exercise program on postural control and balance in individuals with Parkinson's disease.

Parkinson's disease (PD) is the second most common neurodegenerative disorder and affects approximately 1 million people in the United States with total annual costs approaching 11 billion dollars. The most common symptoms of PD are tremor, stiffness, slowness, and trouble with balance/walking, which lead to severe impairments in performing activities of daily living. Current medical and surgical treatments for PD are either only mildly effective, expensive, or associated with a variety of side-effects. Therefore, the development of practical and effective add-ons to current therapeutic treatment approaches would have many benefits. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that can affect brain activity and can help make long-term brain changes to improve functions like walking and balance. While a few initial research studies and review articles involving tDCS have concluded that tDCS may improve PD walking and balance, many results are not meaningful in real life and several crucial issues still prevent tDCS from being a useful add-on intervention in PD. These include the selection of stimulation sites (brain regions stimulated) and tDCS electrode placement. Most studies have targeted the motor cortex (brain region that controls intentional movement), but there is evidence that the cerebellum - which helps control gait and balance, is connected to several other brain areas, and is easily stimulated with tDCS - may be a likely location to further optimize walking and balance in PD. There is also evidence that certain electrodes placements may be better than others. Thus, the purpose of this study is to determine the effects of cerebellar tDCS stimulation using two different placement strategies on walking and balance in PD. Additionally, although many tDCS devices are capable of a range of stimulation intensities (for example, 0 mA - 5 mA), the intensities currently used in most tDCS research are less than 2 mA, which is sufficient to produce measurable improvements; but, these improvements may be expanded at higher intensities. In the beginning, when the safety of tDCS was still being established for human subjects, careful and moderate stimulation approaches were warranted. However, recent work using stimulation at higher intensities (for example, up to 4 mA) have been performed in different people and were found to have no additional negative side-effects. Now that the safety of tDCS at higher intensities is better established, studies exploring the differences in performance between moderate (i.e., 2 mA) and higher (i.e., 4 mA) intensities are necessary to determine if increasing the intensity increases the effectiveness of the desired outcome. Prospective participants will include 10 people with mild-moderate PD that will be recruited to complete five randomly-ordered stimulation sessions, separated by at least 5 days each. Each session will involve one visit to the Integrative Neurophysiology Laboratory (INPL) and will last for approximately one hour. Data collection is expected to take 4-6 months. Each session will include walking and balance testing performed while wearing the tDCS device. Total tDCS stimulation time for each session will be 25 minutes.
