Active clinical trials for "Parkinson Disease"

Dystonia is a disabling symptom affecting both patients with idiopathic Parkinson's disease (PD) and atypical parkinsonism (AP). Botulinum toxinum (BoNT), by blocking muscle contraction, is a possible treatment for focal dystonia. The benefit of BoNT treatment has been proven in some focal dystonia associated with PD or AP. The investigators aim to give an overview of the efficacy of BoNT in a variety of focal dystonia in a large cohort of parkinsonian patients.

DaTSCAN™ (123I-ioflupnae) tomoscintigraphy assesses the density of dopamine transporters (DATs) on the presynaptic membrane of dopaminergic neurons. This examination is used in clinical routine in patients presenting a parkinsonian syndrome in search of a pre-synaptic dopaminergic denervation pointing to a neurodegenerative origin of this syndrome To date, there is little literature data evaluating the influence of psychotropic treatments frequently used in clinical routine on DaTSCAN™ CT images. Some studies have shown that SSRI (selective serotonin reuptake inhibitor) and SNRI (serotonin and norepinephrine reuptake inhibitor) antidepressants can significantly alter striatal ioflupane uptake ratios (10-20%) with no obvious influence on the visual interpretation of the examination . The objective of this study was to evaluate the influence of the most commonly used psychotropic therapies, sometimes in combination, on DaTSCAN™ CT images with a large population of patients included in clinical routine.

The investigators will run an at-home usability study of a newly developed home exercise device (FitMi PD) for individuals with Parkinson's disease. FitMi PD uses embedded sensors that can track and record the user's direction and degree of movement while performing exercises described on a computer.

The purpose of this study is to identify unique profiles of speech and language changes that distinguish individuals with Parkinson's disease from adults without Parkinson's disease and individuals with Parkinson's disease with cognitive (e.g., memory, thinking skills) impairment from those without cognitive impairment.

Background: Researchers have some data on how the brain controls movement and why some people have tremor. But the causes of tremor are not fully known. Researchers want to study people with tremor to learn about changes in the brain and possible causes of tremor. Objective: To better understand how the brain controls movement, learn more about tremor, and train movement disorder specialists. Eligibility: People ages 18 and older with a diagnosed tremor syndrome Healthy volunteers ages 18 and older Design: Participants will be screened with: Medical history Physical exam Urine tests Clinical rating scales Health questions They may have electromyography (EMG) or accelerometry. Sensors or electrodes taped to the skin measure movement. Participation lasts up to 1 year. Some participants will have a visit to examine their tremor more. They may have rating scales, EMG, and drawing and writing tests. Participants will be in 1 or more substudies. These will require up to 7 visits. Visits could include the following: EMG with accelerometry Small electrodes taped on the body give small electric shocks that stimulate nerves. MRI: Participants lie on a table that slides into a cylinder that takes pictures of the body while they do simple tasks. Small electrodes on the scalp record brain waves. A cone with detectors on the head measures brain activity while participants do tasks. A wire coil held on the scalp gives an electrical current that affects brain activity. Tests for thinking, memory, smell, hearing, or vision Electrodes on the head give a weak electrical current that affects brain activity. Photographs or videos of movement Participant data may be shared with other researchers.

This pilot study aims to assess a new device designed for an objective measure of sleep parameters. The purpose of the device is to assess, in a more simple and precise way, the impact of deep brain stimulation on patient's sleep.

To gather data on DBS Therapy effectiveness in different geographic populations.

This retrospective study is a more extensive, confirmatory analysis of the cognitive and functional outcomes initially seen in 2 groups of MCI/dementia patients in Springfield, MA and compares specialized dementia care and a comprehensive treatment approach versus usual care delivered in a non-specialist setting. The first group of patients (n= 328) was seen by a dementia specialist, who utilized a standardized assessment and treatment protocol (CNS). This included comprehensive identification and treatment of hypoxia, sleep-disorders, and other cognitively-impairing metabolic conditions as well as maximally- dosed FDA-approved medications for dementia, depression, and PBA. The second group of patients (n= 280) was seen by non-dementia specialists in the community and received usual care which did not include comprehensive assessment or treatment of underlying metabolic derangements or maximal utilization of currently available medications. This study, evaluating date from a larger cohort (n>800) of specialist-treated cognitively-impaired patients, will further examine the hypothesis that a comprehensive dementia treatment protocol yields cognitive stabilization and/or improvement using already available dementia drugs when compared with usual community care.

This post-marketing evaluation has been designed to consistently investigate the subject's preference when switching from a Medtronic® constant voltage or constant current device to a St Jude Medical Infinity™ or St Jude Medical Brio™ constant current system. As electrodes will not be re-positioned, differences in subject's preference are to be explained by the difference in shape of the delivered pulse or waveform between the two systems.

Introduction: The Parkinson is one of the most common degenerative diseases of the central nervous system , mainly characterized by resting tremor , rigidity, akinesia and postural instability , also featuring the autonomic modulation of heart rate , which can lead to reduced frequency variability heart . Some activities may modify the modulation , including rehabilitation using virtual reality. Method: The research is interventional type , quantity and prospective, where volunteers were chosen for inclusion and exclusion criteria and divided into two groups , Control and Parkinson's, where they underwent 24 sections with virtual reality physiotherapy three times a week . Analysis of the autonomic modulation of heart rate was performed before and after the rehabilitation program with the frequency meter Polar brand. Statistical analysis was performed in 5.2 Biostat program with Shapiro- Wilk test to verify the normality , followed by t test to compare the data.
