Filter by:The objective of this study is to assess the efficacy and safety of a single, kinematic-analysis-based intramuscular injection of NT 201, compared with placebo, in moderate to marked essential tremor of the upper limb.
The objective of this study is to determine if citocoline is effective for balance abnormalities and to stabilize cognitive decline in patients with fragile X-associated tremor ataxia syndrome. The study will test 1000mg twice daily of citocoline for 12 months in an open label pilot study, with study visits at baseline, 3, 6, and 12 months.
Investigators hypothesize that there are specific characteristic of each cognitive and motor condition that can be defined using brains scans.
Essential tremor is the most common adult-onset movement disorder, and essential voice tremor is the vocal manifestation of essential tremor. While nearly all essential tremor patients experience hand tremor, many also manifest head tremor and voice tremor. Essential voice tremor can lead to increased vocal effort, decreased intelligibility, and misconstrued emotional state. Only one medication, propranolol, is FDA-approved to treat essential tremor. Propranolol is not felt to be nearly as effective for axial tremors (head, trunk, neck) as it is for extremity tremors. However, this has not been studied with any objective assessment in a prospective way for EVT. For patients with essential voice tremor, the limited published data suggests that botulinum toxin has been shown to lead to functional voice improvement. Botulinum toxin, though also not well-studied with objective voice outcomes, is a commonly used clinical therapy for treatment of essential voice tremor. While it is used more often for essential voice tremor than propranolol therapy, botulinum toxin also has not been prospectively studied with validated, objective voice outcome measures. The investigators would like to determine if propranolol has any significant effect on vocal tremor. The investigators would also like to determine, in an objective way, the effect of botulinum toxin on vocal tremor. If effective, propranolol would provide an affordable and non-invasive alternative or addition to botulinum toxin injections for patients with essential voice tremor.
Stereotactic lesioning of thalamus and basal ganglia for treatment of tremor is a well-known procedure which, prior to the introduction of deep brain stimulation, or DBS, was usually achieved using stereotactic surgical procedures. Radiosurgery of invisible targets to treat movement disorders and intractable pain are still the domain of frame-based procedures, due to the need of a solid reference system registered to the anterior commissure-posterior commissure (AC-PC) line, which allows the use of stereotactic atlases. In this study we want to utilize a mathematical method that uses atlas-derived stereotactic coordinates to perform frameless images-guided radiosurgery of such functional targets Particularly the aim of the present study is to investigate both the efficacy and the safety of the methodology to treat upper limb and hand tremor in elderly or in patients which are not ot susceptible of surgical procedures. For these reasons a dose escalation prospective trial have been designed.
The purpose of the proposed study is to demonstrate the safety and efficacy of the ANS Totally Implantable Deep Brain Stimulation System in the VIM nucleus of the thalamus implanted for the treatment of tremor due to essential tremor. This study will be included in the Pre-Market Approval Application to support the safety of this device in use.
Deep Brain Stimulation (DBS) is an FDA approved, and widely used method for treating the motor symptoms of Parkinson's Disease (PD), Essential Tremor (ET) and Dystonia. Over 100,000 patients worldwide have now been implanted with DBS devices. The DBS target regions in the brain are the Subthalamic nucleus (STN), the Internal Segment of Globus Pallidus (GPi), or the Ventral Intermediate Nucleus of the Thalamus (VIM). In order to place the DBS electrode in the target location, a combination of two 3D imaging techniques; 3D MRI and CT, are used. Data are also collected from individual nerve cells to help find the best location for the DBS electrode in each patient. This electrode recording takes place during the standard surgical implantation of the DBS electrode, and is part of the standard clinical technique. The investigators plan to collect additional data from populations of neurons during the DBS surgery in an effort to further improve the placement of the DBS electrode. These "Local Field Potentials", LFPs, represent the activity of the collection of neurons surrounding the tip of the electrode, and will be measured during surgery along the path used for the placement of the DBS electrode. The goal of this project is to determine whether this additional data from surrounding neurons will help with optimal placement of the DBS electrode.
Essential Tremor (ET) is characterized by tremors affecting the arms. The investigators will examine the effects of non-pharmacological limb cooling on clinical and physiological characteristics in patients presenting with ET at three different temperatures; and will measure changes in tremor amplitude after cooling of the upper limb.
The purpose of this study is to determine whether transcranial cathodal direct current stimulation (tDCS) delivered over the cerebellum can improve essential tremor.
The clinical utility of deep brain stimulation (DBS) for the treatment of movement disorders such as Parkinson's disease has been well established; however, there is a great disparity in outcomes among DBS recipients due to varied postoperative management, particularly concerning the choosing of an optimal set of programming parameters from the thousands of possible combinations. This study will evaluate the use of motion sensor based assessments to develop a functional map and algorithms to automatically determine a set of programming parameters that maximize symptomatic benefits while minimizing side effects and battery consumption.
