Active clinical trials for "Tremor"

Background: A movement disorder is a condition that causes a person s body to move in ways that are not normal. There are different types. Some disorders cause movements people can t control, such as tics or shaking. Some cause reduced or slow movements. Movement disorders can cause disability in people. Sometimes members of the same family will have the same disorder. Researchers want to learn more about how people develop these disorders. This research could lead to better treatments. Objective: This natural history study will collect data on people with different types of movement disorders. It will also collect data on their family members. The data will support further research. Eligibility: Children and adults aged 2 years and older who have a movement disorder. Family members of people with movement disorders are also needed. Design: Participants will undergo screening. They will have a physical exam. Researchers will look at their existing medical images. Any photographs or videos of their movements will also be reviewed. Most participants will come to the NIH clinic for only 1 visit. They will answer questions about their condition. They will have normal tests used to diagnose their condition. They may have blood tests and different types of imaging scans. They may have tests to see how well their nerves function. The tests used will depend on the type of disorder they have. Family members will have some of the same tests as people with disorders. Participants will not receive any new treatments. Some participants may be asked to return for a follow-up visit. Up to 4000 people may participate.

To compile characteristics of real-world outcomes for Boston Scientific Corporation's commercially approved Deep Brain Stimulation (DBS) Systems, when used according to the applicable Directions for Use, for the treatment of Essential Tremor.

Cerebellocerebral connection plays an important function in motor control. Nowadays it can be investigated with neuroimaging and physiological methods in humans. Cerebellar inhibition (CBI) is a phenomenon showing a physiological suppression of the motor evoked potential (MEP) evoked from the motor cortex (M1) by delivering a preceding transcranial magnetic stimulation (TMS) on the contralateral cerebellum. Despite the mediated pathway is supposed to be the cerebello-dentato-thalamo-cortical (CDTC) circuit, there is no conclusive evidence. In addition, the clinical significant of CBI remains unclear. Based on our previous studies, we found that the patients with advanced tremor show an impaired Bereitschaftspotential. The findings support a notion that the patients with tremor bear dysfunction of the CDTC circuit. Intriguingly, the pathogenesis of the parkinsonian tremor is highly associated with the CDTC circuit. The "dimmer-switch" model suggests that the basal ganglia-thalamo-cortical circuit dysfunction may initiate the resting tremor, and the following CDTC circuit dysfunction will lead to the large-amplitude resting and postural tremor in Parkinson's disease (PD). The intention tremor is usually found in the patients with cerebellar degeneration, which is also relevant to the CDTC circuit dysfunction. We expect that the clinical significance of CBI and the mediated pathway of CBI will be clarified by this study.

The object of this study is to longitudinally collect clinical outcomes of patients receiving deep brain stimulation for movement disorders with the objective of making retrospective comparisons and tracking of risks, benefits, and complications.

Clinical presentation of orthostatic tremor (OT) may be misleading and simply perceived by a postural instability such as in several peripheral neuropathies. In addition, peripheral neuropathies represent the leading cause of pathologies associated with OT. Among patients referred for an electroneuromyogram (ENMG) for peripheral neuropathy and presenting with postural unsteadiness, OT assessment will be systematically performed. Demographic, clinical and polygraphy characteristics of these patients will be analyzed and prevalence of OT in the general population of peripheral neuropathies will be assessed.

This is a multi-centre, single-blind, placebo-controlled trial with an open label follow up. After the baseline assessment, all participants will receive the GyroGlove for two weeks during the open label follow up part of the trial. All gloves will be retrieved and returned to GyroGear after closure of the study.

This study will evaluate the safety and efficacy of T2000 when used to treat patients with moderate to severe essential tremor over a 20 week period. Essential tremor (ET) is a common form of involuntary shaking not related to Parkinson's disease. The medications that are currently used to treat ET work in a small proportion of patients and provide only partial improvement in symptoms. Use of these current medications is also limited by side-effects in many patients. T2000 is a medication currently under development for the treatment of essential tremor. Although T2000 is a new medication, it belongs to a class of medications that has been used for many years for the treatment of a variety of medical conditions. In previous studies, T2000 appeared to be effective in controlling symptoms of ET and some patients with severe ET had major improvements in tremor. T2000 was well tolerated for periods up to 20 days and the minimal side-effects seen were those that would be expected for medications in this class. The current study will evaluate the safety and efficacy of T2000 in patients with moderate to severe essential tremor. Patients will receive doses of T2000 beginning at 600 mg a day, followed by 800 mg a day and up to 1000 mg a day. The total duration of treatment will be 20 weeks. Patient's tremor and neurological examination will be monitored throughout the study. The response to T2000 will be determined by comparing the severity of tremor while patients are receiving T2000 compared to the tremor observed without active medication.

A pilot trial to determine the feasibility of treadmill training with dual training in patients with Fragile X-Associated Tremor/Ataxia Syndrome (FXTAS).

The purpose of this study is to determine if Zonisamide is effective in reducing tremors in patients with Essential Tremor.

A global post approval study to collect safety and effectiveness data related to ExAblate Neuro for the treatment of certain disorders such as Essential Tremor, Parkinson's Movement Disorders, or Neuropathic Pain within the thalamus and/or pallidum.
