Filter by:This is a 24-week, multicenter, randomized, double-blind, placebo-controlled, add-on, parallel-group study to evaluate the effect of rasagiline on cognitive function in adults with mild cognitive impairment (MCI) in Parkinson's disease (PD-MCI).
The purpose of this research study is to find out whether dexmedetomidine changes brain cell activity in the subthalamic nucleus (STN).
This is an observational, multi-center study to assess clinical features and biologic biomarkers in Parkinson's disease (PD) patients compared to healthy controls (HC). The primary objective of this study is to discover clinical and biologic markers of PD for use in clinical trials of disease-modifying therapies.
In this study, the investigators will monitor extracellular neurotransmitter levels using a probe that is able to perform real time electrochemical detection during deep brain stimulation surgery. The overall question this study is designed to answer is: Are there neurotransmitters released during deep brain stimulation?
The purpose of this study is to determine whether performing deep brain stimulation surgery for Parkinson's disease using intraoperative imaging and frameless stereotaxis is noninferior to using frame-based stereotaxy and microelectrode recording.
The aim of this study is to asses the efficacy and the clinical safety of the transcranial magnetic resonance guided high intensity focused ultrasound system ExAblate 4000, InSightec Ltd. for functional neurosurgery in the treatment of movement disorders. The treatments to be conducted in this study are non-invasive, i.e. without opening the skull, and will create microthalamotomies in specific target areas such as thalamus, subthalamus and pallidum. The data obtained in this study will be used to evaluate the basic safety aspects of this new treatment technology and will serve as a basis for the clinical introduction of MR-guided ultrasound neurosurgery.
'Off periods' where people with Parkinson's disease are slow, stiff and unable to function are disabling, and a treatment which can converts people to a "on", good, able to function state would be extremely useful. We assessed safety, tolerability and efficacy of inhaled dry powder apomorphine (VR040) in a clinic-based study in this setting.
In this first study of inhaled apomorphine in Parkinson's disease patients, the primary objective is to find the minimum efficacious dose of apomorphine that is useful in rescuing patients during 'off' periods. Safety, tolerability and pharmacokinetics of inhaled apomorphine will be assessed during the study.
Parkinson's disease is a chronic progressive neurological disorder. Symptoms are tremor, slowness in movement, rigidity and postural instability. As the disease progresses and treatment with L-dopa is no longer sufficient, some patients may be treated with deep brain stimulation. When treated with deep brain stimulation, electrodes are inserted in the affected area of the brain and through stimulation, motor symptoms of Parkinson's disease are significantly reduced. During the first year of DBS treatment patients and spouses may experience changes in everyday life and illness trajectory posing new opportunities as well as new challenges. The purpose of the study is to develop an individualised and targeted nursing program to support patients and relatives manage changes and challenges in life the first three months after Deep Brain Stimulation. The intervention is expected to generate important knowledge that will serve as a foundation for the further development of a future nursing program.
The objective of this experiment is: - Primary: To determine the effects of tyrosine supplementation on orthostatic hypotension in people with PD. - Secondary: To determine the effects of tyrosine supplementation in people with PD with autonomic insufficiency on HR, BP, and norepinephrine responses during acute exercise stress. Orthostatic hypotension and autonomic abnormalities are a common problem for individuals who suffer from PD, especially as it leads to lightheadedness and falling. For those affected, it can drastically reduce quality of life. It has been hypothesized that tyrosine may impact upon individuals suffering from PD. There is ample evidence in animal models that supports our theory; however there is no clinical evidence of the impact tyrosine supplementation may have in PD patients who suffer from orthostatic hypotension and blunted BP and HR responses. Positive findings that supplemental tyrosine increases BP and HR in people with PD during daily activities such as standing up from a chair and walking can lead to new therapies to improve Parkinsonian orthostatic hypotension. Hypothesis We will test the hypothesis that symptomatic individuals with PD on dopamine therapy who suffer from orthostatic hypotension and blunted HR and BP responses will improve after tyrosine supplementation.
