Filter by:To test whether a multidisciplinary intensive rehabilitation treatment (MIRT) slowed down the progression of the disease in Parkinson's disease (PD) "de novo" patients, all treated with Rotigotine, in a randomized controlled study with a 18 months follow-up.
Objective: To analyze different parameters in patients with Parkinson's Disease (PD) obtained through the use of a stabilometric platform and compare them with those of a control population. To interpret the data in order to find some postural instability indicators that can become useful to build a rehabilitation strategy for balance disorders in PD.
The aims of this study is to assess the efficacy of the crossover on balance in Parkinsonian patients and compare this results with the results of a control group of patients treated with a stabilometric platform.
An open-label randomized study to evaluate the Safety, Tolerability, and PK of Low and High single doses of ND0612 (i.e. LD/CD ratio 60/7.5 mg/mL and 60/14 mg/mL), as well as the combination with oral Entacapone (concomitant catechol-O-methyl transferase [COMT] inhibitor) in PD subjects with well-defined morning "OFF" and a good response to LD. Exploratory efficacy parameters were collected (early evidence of effectiveness as part of Phase 1).
This single ascending dose study is to determine safety, tolerability, pharmacokinetics and immunogenicity of PRX002 in approximately 40 healthy subjects.
The objective of this study is to investigate the efficacy and safety of two different dose levels of NT 201 (75 U or 100 U per cycle), compared with placebo, in reducing the salivary flow rate, and the severity and frequency of chronic troublesome sialorrhea that occurs as a result of various neurological conditions in adult subjects.
Mild cognitive impairment and dementia are frequent non-motor complications of moderate to advanced Parkinson's disease. Brain positron emission tomography (PET) study findings confirm post-mortem evidence that cholinergic loss is related to cognitive impairment in Parkinson's disease. However, current cholinergic augmentation therapy is not always effective and it should only target those Parkinson's disease patients who have evidence of cholinergic system impairment. The objective of this study is to study the association of a particular subtype of cholinergic receptors, so-called nicotinic acetylcholine receptors, with cognition in Parkinson's disease using a novel PET marker of cholinergic system integrity.
Parkinson's disease, a degenerative disorder of the dopaminergic system, combines motor symptoms but also non-motor, such as depression, sleep disorders and circadian rhythms and impaired cognitive functions. Difficulties in balancing the dopaminergic treatment of these patients emphasizes the need to find effective adjuvant therapies. Light therapy (LT) represents one such innovative therapeutic approach. Although light has an obvious to visual pathways within the brain, today it is known to additionally exert non-visual effects throughout the body. Recently our team has shown that non-visual, non-circadian light plays a major role in the regulation of sleep, as well as cognitive brain function in general. The retina, the primary conduit for the transmission of light information is weakened or thinned in Parkinson's patients. The dopamine system is known to enhance the processing of light information and intraocular injection of L-dopa in animal models of Parkinson's disease, can reverse associated motor symptoms. This allows for the possibility that LT would strengthen the dopaminergic tone in the central nervous system. However, to this date its effectiveness for alleviating Parkinson's symptoms has only been suggested by two studies, both poorly controlled. Thus, through the convergence of basic and clinical data, a study examining the effect of LT directly in people Parkinson's disease symptoms, whilst controlling for the effects on sleep, circadian system, mood, and cognitive functioning, is of extreme importance. With this information our hope is to determine if these polymorphisms allow for a predictive model of response to LT treatment.
To retrospectively investigate the relationship between the Cholinergic Pathways Hyperintensities Scale (CHIPS) score and the change of cognitive status of Parkinson's disease (PD) patients after bilateral subthalamic nucleus deep brain stimulation (STN DBS).
Deep Brain Stimulation (DBS) is an FDA approved, and widely used method for treating the motor symptoms of Parkinson's Disease (PD), Essential Tremor (ET) and Dystonia. Over 100,000 patients worldwide have now been implanted with DBS devices. The DBS target regions in the brain are the Subthalamic nucleus (STN), the Internal Segment of Globus Pallidus (GPi), or the Ventral Intermediate Nucleus of the Thalamus (VIM). In order to place the DBS electrode in the target location, a combination of two 3D imaging techniques; 3D MRI and CT, are used. Data are also collected from individual nerve cells to help find the best location for the DBS electrode in each patient. This electrode recording takes place during the standard surgical implantation of the DBS electrode, and is part of the standard clinical technique. The investigators plan to collect additional data from populations of neurons during the DBS surgery in an effort to further improve the placement of the DBS electrode. These "Local Field Potentials", LFPs, represent the activity of the collection of neurons surrounding the tip of the electrode, and will be measured during surgery along the path used for the placement of the DBS electrode. The goal of this project is to determine whether this additional data from surrounding neurons will help with optimal placement of the DBS electrode.
