Filter by:The purpose of this study is to determine whether the gastric retentive Accordion Pill™ Carbidopa/Levodopa (AP-CD/LD) is more effective than the commercially available immediate release Carbidopa/Levodopa in reducing motor fluctuations such as "off time" in advanced Parkinson's Disease patients.
The purpose of this study is to evaluate the blood brain barrier in the striatum of patients that have other types of movement disorders compared to patients with Parkinson's Disease that are receiving similar treatment, to determine if a there is a disruption of the blood brain barrier in patients with Parkinson's Disease.
An Open-Label Study in Healthy Male and Female Subjects to Identify the Concentration that Provides Optimal Bioavailability of Levodopa Infused Subcutaneously via a Pump System; and to Compare the Bioavailability of Levodopa/Carbidopa Solution to that of Levodopa/Carbidopa Intestinal Gel (LCIG), Infused via a Naso-Jejunal Tube
This is the first study on the effect of the variable frequency stimulation (VFS) on Freezing of gait (FOG) in Parkinson's disease (PD) patients with STN DBS. FOG has responded poorly to High frequency stimulation (HFS) but can be alleviated by relatively VFS. This study would have significant clinical implications in the management of Freezing of gait (FOG) in these PD patients with subthalamic nucleus (STN) DBS. The investigators hypothesize that VFS could have better effect on FOG than HFS and low frequency stimulation (LFS).
The objective of this protocol is to investigate the microstructural alterations and monoaminergic function in Parkinson's disease patients with impulse control disorders and cognitive impairment by multimodal MRI and 18F-DTBZ PET imaging.
Parkinson's disease (PD) is a common neurodegenerative disorder affecting approximately 80,000 Veterans, representing a priority area for VA research. Current medicines for PD only improve symptoms, treatments that slow disease progression are needed, and earlier diagnosis of PD may be the key to their development. PD symptoms can be mimicked by medicines (most commonly antipsychotic drugs that block dopamine), and some of these patients actually have underlying "prodromal" PD that was "unmasked" years before it would have caused symptoms. This problem is increasing as these medicines are now used for common conditions including post-traumatic stress disorder and depression. The investigators will identify prodromal PD in patients with drug-induced symptoms using brain scans. These patients will be enrolled in a randomized clinical trial of aerobic exercise which slows progression in animal models of PD and has other health benefits. The investigators will measure the effect of exercise on symptoms, disease progression (using brain scans) and markers of PD risk (using blood tests). These studies will improve early PD diagnosis and potentially identify a way to slow progression of PD.
The purpose of this study is to evaluate safety and effectiveness of the peripheral mechanical stimulation of the feet on gait variables, clinical status, risk of falls, BDNF levels, immunological profile and brain functional connectivity changes in patients with Parkinson's disease.
The purpose of this randomized, controlled interventional study is to determine the effects of a high intensity exercise training program on objective sleep measures, daytime sleepiness, mobility, and brain health/functional connectivity in patients with Parkinson's disease.
The primary objective of this study is to evaluate the efficacy of buspirone in combination with amantadine in reducing levodopa-induced dyskinesia (LID) in patients with Parkinson's disease (PD).
54 patients with idiopathic Parkinson's disease and freezing of gait resistant to subthalamic nucleus stimulation and dopaminergic medication will be included into this multicentre randomised controlled double-blinded parallel group clinical trial. The treatment consists of two different stimulation settings using (i) conventional stimulation of the subthalamic nucleus [standard STN] as active comparator and (ii) combined stimulation of active electrode contacts located in both the subthalamic nucleus and substantia nigra pars reticulata [STN+SNr].
