Active clinical trials for "Parkinsonian Disorders"

Parkinsonian syndrome is clinically characterized by the presence of resting tremor, rigidity, bradykinesia and postural instability. Parkinsonian disorders include Parkinson's disease (PD), progressive supranuclear palsy (PSP), corticobasal dementia (CBD), multiple system atrophy (MSA) and vascular parkinsonism (VP). Each of these diseases has a singular physiopathological origin, course and prognosis. Numerous imaging studies consequently aimed at finding markers to early make the distinction between the different types of parkinsonism, in order to identify patients who could benefit from dopaminergic agonist therapy. Excessive iron deposition in the subcortical and brainstem nuclei has been described in numerous neurodegenerative disorders including Parkinson's disease. Increased iron levels are more frequent in area that are rich in dopaminergic neurons and have been implicated in the development of movement disorders, the distribution of areas with increased iron deposition however varying according to parkinsonism types. Iron deposition quantification could thus potentially help in differentiating parkinsonism types and could improve therapy guidance. Quantitative susceptibility mapping (QSM) locally estimates the magnetic susceptibility of brain tissues based on gradient-echo signal phase. The local susceptibility being sensitive to the presence of paramagnetic susbtances, QSM allows the non-invasive evaluation of iron distribution and quantification in the brain with high image quality (Liu et al., 2013). However, since iron deposition followed an exponential curve during normal aging in most of the basal ganglia the potential of QSM to distinguish between healthy and parkinsonian subjects in elderly remains unclear. The aim of this study was thus to determine susceptibility values in the basal ganglia of elderly patients with parkinsonian syndromes, to compare these values to healthy aged-matched controls and between parkinsonian syndrome types. Secondly, investigators aimed to evaluate microstructural changes in the basal ganglia using diffusion tensor imaging (DTI) in the same population and to determine whether susceptibility and DTI parameter changes are correlated. Finally investigators sought to assess the relation between susceptibility/DTI parameter values in the basal ganglia and behavioral measures of motor and cognitive abilities.

The purpose of this study is to determine whether clonazepam is effective and safe in the treatment of rapid eye movement behavior disorder (RBD) of patients with Parkinson's disease (PD).

This study will assess the efficacy and safety of modified release AFQ056 in patients that have Parkinson's Disease L-dopa Induced Dyskinesias (PD-LID)

The aim of this project is to evaluate the needs and provision of care for patients in the late stages of Parkinsonism and their carers in several European countries, to compare the effectiveness of different health and social care systems, and to lay the foundation for improved outcomes in this population. The investigators will undertake an in-depth assessment of patients and their care arrangements in a population recruited through networks in six European countries. The systems and procedures that are used in the provision of care will be reviewed through a systematic literature review, interviews and assessments of patients, carers and health care providers, and through a trial comparing assessment by a specialist with management suggestions, guidance and access to telephone advice to that of usual care. Through interviews, questionnaire assessment and review of current health-care and social care arrangement, the investigators will assess the needs, provision of care and use of health-care resources, and their impact on patient and carer outcomes in different countries. National and regional databases will also be interrogated to identify current practice and use of healthcare resources and drug usage. A systematic literature review of the evidence for effective management strategies, analysis of the study data, and evaluation of change in outcomes following specialist review will provide the basis for recommendations in the management of late stage Parkinsonism. The investigators will also evaluate potentially useful outcome measures for use in this patient group. In addition to charting the needs and current care provision for late stage Parkinsonism in different European countries, its cost and effectiveness, and an analysis of health-care and social care predictors of improved outcome, the project will produce a platform for the assessment of patients with late stage Parkinsonism, their current treatment and care provision, as well as guidelines on the management of this late disease phase.

Objective of the study: To test the efficacy of cerebellar transcranial direct current stimulation (tDCS) associated with physical rehabilitation on postural instability and falls in progressive supranuclear palsy using a double-blind design and wearing sensors technology Design: Twenty probable PSP patients with no dementia and still able to walk will be recruited for a randomized double-blind sham-controlled study. Each patient will be hospitalized for a four week physical rehabilitation. In the real-arm, the patients will undergo a ten cerebellar tDCS stimulations while the placebo arm will undergo sham stimulation. Each patient will be evaluated before and after stimulation by PSP-rating scale (PSP-RS), cognitive tests and a battery of gait and movement tests using wearing sensors technology.

This is a 44-week, randomized, placebo-controlled, double-blind, single-center, phase 1 clinical trial consisting of a dose-escalation Part A study in healthy participants, followed by a Part B in participants with Parkinson's disease with a selected doses from Part A.

The primary objective of the study is to obtain preliminary safety and tolerability data with davunetide (NAP, AL-108) in patients with a tauopathy (frontotemporal lobar degeneration [FTLD] with predicted tau pathology, corticobasal degeneration syndrome [CBS] or progressive supranuclear palsy [PSP]). The secondary objectives of this study are to obtain preliminary data on short term changes (at 12 weeks) in a variety of clinical, functional and biomarker measurements from baseline, including cerebrospinal fluid (CSF) tau levels, eye movements, and brain MRI measurements.

This is a randomized, placebo-controlled, 3-period crossover, balanced, single-site, third party-blind study of preladenant (SCH 420814) in participants with Parkinson disease (PD) to be conducted in conformance with Good Clinical Practices. This trial will investigate the effects of single doses of preladenant and placebo on the dyskinesia and antiparkinsonian actions of a levodopa infusion. The study will examine 10 mg ("low dose") or 100 mg ("high dose") study drug, given as single, oral administrations in conjunction with intravenous (IV) levodopa infusion and oral carbidopa.

We initiate a study with research grant from department of health and Taoyuan mental hospital and choose risperidone and olanzapine as study medications. We compare the incidence of using anticholinergic drugs in schizophrenic patients of Han ethnics with neuroleptic-induced acute dystonia or parkinsonism to test the hypothesis that these two medications have different EPS incidence in EPS intolerant population.

The purpose of this study is to examine the short term effects (12 Weeks) of Lactobacillus plantarum PS128 (PS128) on Parkinson's disease (PD) symptoms.
