While positron emission tomography/computed tomography (PET/CT) can assist in the diagnosis of Parkinson disease (PD), it can also potentially help monitor treatment options for PD. One such experimental therapeutic option for PD is fetal dopaminergic transplantation trials. A potential goal of such novel therapies is to replace deficient dopaminergic neurons in PD. Researchers at the University of Saskatchewan have been at the frontier of these exciting treatment options. [18F]FDOPA PET/CT imaging has been successfully used by some authors to monitor engraftment and assess efficacy of fetal dopaminergic transplant . This study also aims to utilize [18F]FDOPA PET/CT imaging to potentially aid in detecting alterations in the dopaminergic pathway from these innovative surgical treatment options. There are two main objectives of this study: 1) Evaluate the effectiveness of fetal dopaminergic grafts in patients with PD using FDOPA PET imaging pre and post-surgical implantation and a secondary longer term goal 2) Correlate the [18F]FDOPA PET/CT findings in early PD with post-mortem pathological analyses of PD
In a computerized experiment, visual stimuli will be presented to the parkinson's disease patients and to the controls. They will respond to each image by acting on the keyboard in a specific manner. Each participant will repeat that task 384 times per session. A break will be inserted every 12 tests so that participants can rest. The experiment consists of three sessions. Each image will be presented three times. For the first two presentations it is assumed that a link will be created between the image and the task, and the image and action. In the third presentation, the same task and the same action will be maintained or will be swapped. In this way, It can be checked whether associations thus generated will affect the performance of the participants when tasks and actions will be incongruent.
The effect of varenicline, an alpha4beta2 nicotinic receptor partial agonist on excessive daytime sleepiness in Parkinson's disease will be studied in a randomized, double blind, placebo-controlled clinical trial with a within-subject crossover design.
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.
This is a phase I, randomised, placebo-controlled study to assess the safety and tolerability of two 2-weeks cycles of i.c.v. administration of sNN0031 infusion solution to patients with PD of moderate severity with persisting on-off symptoms in spite of other PD medications.
The purpose of the proposed study is to demonstrate that the functional outcomes of DBS surgery utilizing the "asleep" technique are not inferior to those reported for traditional "awake" DBS technique.
This study will evaluate the effects of transcranial direct current stimulation (tDCS) in combination with locomotor training in patients with Parkinson's disease (PD) and freezing of gait (FOG).
Skin reactions as a result of continuous subcutaneous apomorphine infusion occur frequently and interfere with the absorption of apomorphine. The histopathology of apomorphine-induced skin reactions is poorly understood. Therefore treatment options are limited and suggestive. Objective: to investigate the efficacy of four treatments including massage, dilution of apomorphine, treatment with topical hydrocortisone and pre-treatment with subcutaneous administered hydrocortisone, in Parkinson's disease patients with apomorphine-induced skin reactions.
The purpose of this study is to assess the effectiveness of a forced exercise aerobic exercise program, utilizing a cycling activity, on specific gait parameters and balance in individuals with Parkinson's Disease (PD). Design: pilot, feasibility, randomized control, evaluator blinded. Subjects: Twenty four patients with idiopathic PD Hoehn and Yahr (H&Y) stage II or III. Intervention: Participants randomly assigned to one of two exercise groups, forced exercise or self selected exercise, on cycling machine three times a week for 8 weeks. Both groups to exercise at same aerobic intensity level to keep heart rate at 60-80% heart rate max. Outcomes: Gait parameters of step length, width, and variability as measured by the GAITRite; 6 Minute Walk Test; mini-BESTest (balance testing); exercise tolerance via Patient Reported Outcomes Measurement Information System (PROMIS) scale.
