Parkinson's disease (PD) is known for its motor symptoms and affects more than 100,000 Canadians. However, PD patients also show cognitive deficits and neuropsychiatric problems that significantly impair their quality of life. The occurrence of dementia in PD is much higher than in the general population. The proposed study will allow the principal investigator, his team and his collaborators to investigate the origins and evolution of the cognitive and neuropsychiatric symptoms. Participants with PD with and without mild cognitive impairment (MCI) and participants with and without MCI over the age of 60 years will be assessed during eight study visits over three years. Through brain imaging, clinical testing, as well as genotyping the cognitive patterns in the four different groups will be observed and compared. The results will be used to identify biomarkers that can predict the occurrence of dementia early in the disease. Ultimately, the results of the proposed research will contribute to interventions and treatment strategies tailored to different cognitive profiles in PD before the occurrence of dementia.
The purpose of this study is to examine the efficacy and safety of SQJZ Herbal Mixtures on non-motor symptoms of PD patients.
The purpose of this study is to allow evaluation of long-term clinical effect and safety outcome of treatment with AP-CD/LD, as well as to allow patients to benefit from extended treatment duration with AP-CD/LD after they have successfully completed the Phase 3 core study IN 11 004 ('core study', a phase III, multicenter, randomized, double-blind, double-dummy, active-controlled Phase 3 study to assess the safety and efficacy of AP CD/LD versus IR CD/LD in fluctuating PD patients).
INTRODUCTION: Parkinson's disease (PD) is a neurodegenerative disorder that causes motor disorders such as bradykinesia, rigidity and tremor. In addition to the motor symptoms occurring in the overall PD patients, mostly there is associated respiratory disorders. The respiratory impairment may be due by postural changes, limiting the flexibility and expandability of the chest wall causing decreased lung volumes and flows. So the exercise Proprioceptive Neuromuscular Facilitation (PNF) is a tool designed to reduce the changes in respiratory function, the commitment of the respiratory muscles, and allows greater flexibility of the chest wall, reducing the rigidity of the rib cage. To evaluate the effects of respiratory pattern of Proprioceptive Neuromuscular Facilitation on the distribution of pulmonary ventilation, compartmental volumes of diaphragmatic mobility and functional capacity in patients with Parkinson's disease. METHODS: The study is a clinical trial randomized, in which participants to be elected for the study should present diagnosis of PD, staging of disease between II and III according to Hoehn and Yahr. Initially, the participants will undergo the collection of data on medical history, assessment of pulmonary function by spirometry and respiratory muscle strength measured by the manometer. Then will undergo evaluation of the breathing pattern and tricompartmental distribution of the volume of the chest wall by hemithorax by Plethysmography Optoelectronic; Quantify the mobility of the right diaphragm in total lung capacity for maneuver and during the current volume by ultrasonography. After the evaluation, participants will undergo intervention which will consist of three stages: first occur first session of the PNF later aerobic training for 30 minutes, ending with one PNF session.
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].
Dysfunctions of the lower urinary tract are non-motor symptoms common engines in Parkinson's disease (PD). Urodynamic changes in PD include overactive bladder (OB), characterized by urgency with or without urge incontinence , usually with frequency and nocturia . The aim of this study is to evaluate the efficacy and effectiveness of the treatment of OB in patients with PD with the use of a specific treatment: Posterior Tibial Nerve Electrostimulation (PTNE).
The aims of this proposal include tests of hypotheses of the pathogenetic mechanisms of noradrenergic neurotransmission in Parkinson's disease in vivo, using positron emission tomography of patients with early and advanced Parkinson's disease with or without 3,4 L-dihydroxyphenylalanine (L-DOPA) - induced dyskinesia or co-morbid depression, and evaluation of whether these mechanisms can be influenced therapeutically. Hypotheses: 1. The investigators argue that release in human cortical and subcortical brain regions of norepinephrine (NE) derived from metabolism of exogenousL-DOPA is greater in Parkinson's disease patients with L-DOPA- induced dyskinesia than in patients without this complication. This hypothesis will be tested by measuring antagonist [11C]yohimbine binding to alpha-2 adrenoceptors before and after L-DOPA challenge. 2. If so, it is argued that the greater rise of norepinephrine, measured as [11C]yohimbine displacement after L-DOPA challenge, is the result of down-regulation or loss of norepinephrine transporters. This hypothesis will be tested by measuring the binding of [11C]MeNER, a tracer of norepinephrine transporters. 3. If so, the investigators argue that the greater decline of [11C]MeNER binding is significantly correlated to the symptoms of Parkinson's disease, as proof that patients with more severe loss of noradrenergic terminals exhibit more severe motor deficits.
Following the so call "honey moon" period, motor symptoms of Parkinson's Disease (PD) become difficult to control with dopaminergic treatments alone. Deep brain stimulation (DBS) of the subthalamic nucleus and internal globus pallidus helps to treat fluctuating parkinsonian patients restoring a decent quality of life. However, DBS need a long, complex and invasive surgery to succeed. Thus, there is a critical need to develop alternative treatments, more accessible and less invasive. Thoracic posterior spinal cord stimulation has been used for decades to treat chronic neuropathic pains. Safety and efficacy have already been demonstrated in neuropathic pain. Experimentally, SCS has also demonstrated to improve locomotor activity in two different rodents' models of parkinson's disease. The purpose of this study is to determine whether thoracic SCS is safe and could induce a benefit motor parkinsonian symptoms without any impact on cognitive function and axial disability.
The main objectives for this study are: 1. To investigate novel, non-invasive ocular measurements including optical coherence tomography and eye tracking in a cross-sectional study of participants with various neurodegenerative dementias against standard cognitive assessments and brain imaging measures; and 2. To assess the potential utility of ocular assessments for early detection in the pre-dementia, i.e. the so-called Mild Cognitive Impairment (MCI) stage, across the common neurodegenerative dementia syndromes and, Vascular Cognitive Impairment (VCI) due to small vessel disease (SVD). 3. To determine the prevalence and relevance of amyloid uptake on PET scanning across the dementias most commonly associated with amyloidosis. Specifically we aim to examine correlations with amyloid uptake status in patients symptomatic from the most common proteinopathies (ie amyloid, tau, synuclein) combined in varying degrees with the most common vasculopathies (ie small vessel disease) using multimodal structural and functional imaging, cognitive behavioral, and gait and balance measures, taking into account genetic risk markers (particularly apolipoprotein E genotypes) and fluid biomarkers ( eg cytokines, oxidative stress, lipidomics).
