Filter by:The investigators aim is to study neuropsychiatric symptoms and underlying abnormalities in resting-state fMRI in patients with Parkinson's disease (PD) suffering from neuropsychiatric fluctuations, to enhance the understanding of the pathophysiological mechanisms underlying neuropsychiatric symptoms.
This open-label study is designed to assess the long-term safety and tolerability of dipraglurant in PD patients for up to 52 weeks (at doses of 150-300 mg per day) for patients that have completed an Addex sponsored double-blind clinical trial of dipraglurant.
The proposed control intervention trial, aims to analyse the effects of Dance in the turning characteristics in patients with Parkinson Disease (PD) using three- dimensional (3D) analysis during the timed up and go (TUG) test.
With the aging of the population due to an increase in longevity, the number of people with Parkinson's disease is increasing (166,712 in France, as of December 31, 2015) and the number of patients with motor or cognitive-behavioral disorders is already a major public health challenge (1). In neurodegenerative diseases, the current strategy is to identify the disease early and, if possible, to consider therapeutic measures to slow down the progression of the disease. Classically, when faced with the early stages of Parkinsonism, the investigators differentiate idiopathic Parkinson's disease (IPD) from atypical Parkinsonian syndromes (AP), which include multiple system atrophy (MSA), corticobasal degeneration (CBD), and progressive supranuclear palsy (PSP), for which the prognoses are more severe and the therapies less effective. In the early stage of the disease, when the symptoms are not do no yet differentiate the diseases, the differential diagnosis between IPD and PSP is a real challenge for clinicians (2). Cerebral MRI can help in the diagnosis but is most often only an indicator, as it may be normal in the early stages of the disease (2). The recent emergence of targeted therapies, specific to tauopathies or synucleinopathies, makes it essential to establish a diagnosis as early as possible in order to curb the evolution of the disease (3). The investigators propose here a first study on the analysis of biomarkers of neurodegeneration from lipid metabolism allowing to discriminate IPD and AP from peripheral blood. Two recent studies have provided evidence of the discriminatory character of neurofilament blood testing in the early phases of parkinsonism (4,5). On the other hand, to our knowledge, none of them has studied markers from mitochondrial and peroxisomal metabolism, which could play a key role in the pathophysiology of these diseases (6,7,8,9,10). Our strategy will therefore be to study idiopathic or atypical Parkinsonism subjects with a clearly established diagnosis in a cross-sectional manner, and to identify one or more blood markers of neurodegeneration predictive of IPD or AP, hypothesizing that these markers will be at significantly different levels between the two groups (descriptive analysis). The markers studied will include markers of neurodegeneration, markers of mitochondrial function, peroxisomal function and oxidative stress. The investigators will then study the correlations between these biomarkers and motor scores of disease severity.
Gait difficulties are common in Parkinson's disease (PD) and cause significant disability. No treatment is available for these symptoms. Spinal Cord Stimulation (SCS) has been found to improve gait, including freezing of gait, in a small number of PD patients. The mechanism of action is unclear and some patients are nonresponders. With this double-blind placebo-controlled proof of concept and feasibility imaging study, we aim to shed light on the mechanism of action of SCS and collect data to inform development of a scientifically sound clinical trial protocol. We also hope to identify imaging biomarkers at baseline that could be predictive of a favourable or a negative outcome of SCS and improve patient selection. Patients will be assessed with clinical rating scales and gait evaluations at baseline and 6 and 12 months after SCS. They will also receive serial 18F-FDG and ([18F]FEOBV) PET scans to assess the effects of SCS on cortical/subcortical activity and brain cholinergic function
The principal motor features of Parkinson's disease (PD) include rigidity, tremor, bradykinesia, and postural instability. These motor deficits might cause gait dysfunction including reduced gait velocity, stride length, arm swing, and increased gait variability. Among these, increase in gait variability increased fall risk and served as a marker of disease progression. Previous studies reported that some factors might influence gait variability. However, which one contributes most has not yet been verified. Therefore, the purpose of the present study is to identify the more related influencing factors on gait variability in people with PD.
The purpose of this study is to investigate the long-term effects of treatment with the selective post-synaptic a1-adrenergic blocker terazosin on serial in a population of subjects with defined pre-motor Parkinson's disease (PD) risks and abnormal imaging exams. Imaging changes will be correlated to the presence and severity of motor and non-motor symptoms of PD, measured by validated clinical scales and cardiac autonomic function tests.
Parkinson's disease is characterized by cardinal motor signs such as bradykinesia, tremor, rigidity and postural instability. In addition to these findings, motor freezing, gait disorders, posture disorders, decreased arm swings and loss of axial rotation are also seen. About 80% of the causes of falls in Parkinson's patients are due to postural instability and motor freezing, and patients' quality of life is significantly affected. In addition, gait disorders are common in advanced stages of Parkinson's Disease. Gait disorders decrease the quality of life by increasing the risk of falls, fractures and mortality. Therefore, the aim of this study is to observe the change in gait, foot pressure distribution and balance parameters of Parkinson's patients with and without motor deceleration compared to each other and healthy controls and to determine the relationship between these parameters.
Parkinson's Disease is a progressive condition which affects the nervous system causing tremors, slowed movement and often causes problems with memory and initiation. Treatment management can be complex and challenging for patients and families. Poor memory in Parkinson's disease has been shown to reduce a person's ability to manage activities of daily living, including tasks associated with treatment such a taking medications. However, patients with Parkinson's have been shown to benefit from external reminders. The aim of this research project is to investigate whether the use of a reminder app that has been designed for use by people with cognitive difficulties improves completion of activities related to therapy goals in people with Parkinson's Disease, aiding self-management of their condition. Patients seen in movement disorder clinics in NHS Greater Glasgow and Clyde with a diagnosis of Parkinson's disease, and a partner or carer who can monitor progress, will be invited to participate. Measures of memory, emotional wellbeing and quality of life will be completed to characterise each participant. Participants will have a randomly allocated initial baseline period of either 10, 16 or 22 days in which their rate of completion of intended activities will be monitored. Then, during the intervention period of 3 weeks (21 days) the ApplTree app will be introduced to remind participants of treatment goals. Participants will create specific and personalised treatment goals at the beginning of the monitoring period. Goals will be everyday activities relevant to the management and treatment of Parkinson's disease. The number of goals is not limited and will depend on how frequent targeted behaviours are. However, at least one target behaviour a day in total will be recommended. E.g. Completing daily exercises. Partners will monitor their goal attainment, via a daily/weekly monitoring form in both phases of the study.
Vibration applied to the skin has been anecdotally reported to potentially improve motor control in patients with movement disorders including Parkinson's disease, however few devices have been studied formally. In this study, the investigators will test the effect of skin surface vibration applied non-invasively to patients with movement disorders to determine if there are any beneficial effects on common tasks of motor control and/or abnormal motor symptoms in patients with Parkinson's disease (PD), essential tremor (ET), and dystonia.
