Parkinson's disease (PD) is a neurodegenerative disease characterized by the neurodegeneration of substance nigra pars compacta (SNpc) and the formation of alpha-synuclein protein aggregates in neurons. Although most PD patients are sporadic, it is now clear that genetic factors contribute to the pathogenesis of PD. Indeed, LRRK2 G2019S mutation is one of the most common causes of familial PD. The phenotype corresponding to this mutation is a late-onset form of PD characterized by the accumulation of the N-ethylmaleimide sensitive factor (NSF) in neurons. It is due to a dysfunction of the physiological autophagy processes occurring at cellular level, mainly affecting autophagy mediated by chaperone proteins (Chaperon Mediated Autophagy, CMA), responsible for the clearance of alpha synuclein at the lysosomal level. This condition, although sensitive to treatment with L-DOPA and dopamine agonists, does not currently have any specific therapy. Recently, in a mouse model carrying the LRRK2 mutation, it has been demonstrated that treatment with trehalose is able to reduce the accumulation of NSF deposits in neurons of various brain areas such as the substantia nigra, striatum, cortex and hippocampus. The reduction of protein aggregates correlates with intracellular molecules related to the activation of apoptotic processes in damaged neurons. Moreover, it has been found a significant improvement in motor and cognitive performance. The aim of the present study is to evaluate the safety and tolerability of trehalose in two groups of patients affected by idiopathic PD and PD carrying the LRRK2 mutation, respectively. Moreover, the investigators will collect preliminary data on the effect that this molecule potentially has on disease course in both groups. The treatment duration will be 24 weeks and the overall study duration approximately 12 months. The populations observed will be composed of subjects affected by idiopathic PD and familial PD carrying the genetically confirmed LRRK2 mutation. Enrolled subjects will daily take trehalose in oral administration. Safety will be assessed by detecting any adverse events and analyzing blood chemistry parameters. The effect of trehalose will be evaluated through periodic clinical examinations, including the administration of specific scales and questionnaires.
Small muscles of the hand are affected due to involuntary movements and slowing of voluntary movements seen in Parkinson's disease. There is a loss of fine dexterity and coordination in the hand. It becomes difficult for patients to grasp and release of the objects. They become unable to perform daily activities such as buttoning up, holding keys, brushing teeth, holding forks, spoons and glasses, and writing. Therefore, a certain part of the rehabilitation program should be devoted to upper extremity rehabilitation. The aim of this study was to compare the effects of action observation therapy and mirror therapy, which have been used in the literature for many years, on upper extremity functions and quality of life in individuals with Parkinson's disease.
Parkinson's disease (PD) is the second most common neurodegenerative disease after Alzheimer's disease. Motor symptoms include rigidity, bradykinesia, tremor, and postural instability, these motor symptoms can cause gait dysfunction. Non-motor symptoms include depression, dysarthria, cognitive disability, and sleep disturbance. Although these symptoms can be improved through drug treatment, when the course of PD reaches the middle to late stage, it will still face the situation of weakened drug efficacy and the drug side effects increased. When medication can no longer adequately control the motor symptoms of PD, deep brain stimulation (DBS) becomes a powerful option. DBS is a surgical treatment that involves implanting one or more electrodes into specific areas of the brain, which deliver electrical stimulation to regulate or destroy abnormal neural signal patterns in the target area. The effect of DBS has been proven whether it is in improving motor-related symptoms or non-motor-related symptoms, but there are still some areas that have not been compared before and after the surgery, such as: gait variability, executive functions and dual-task walking. In addition, the parameters of electrical stimulation for DBS will also affect the clinical characteristics of patients. Due to the large difference between individual cases, the recommendation of the electrical stimulation frequency still not be established. Therefore, the influence of DBS and its parameters on the symptoms of PD is a topic worthy of discussion. Purposes: (1) To investigate the long-term effects of DBS on the symptoms of PD. (2) To investigate the effects of DBS stimulation frequencies on walking performance and executive function in individuals with PD.
The clinical trial aims to evaluate the safety and effectiveness of bilateral subthalamic nucleus (STN) and Globus Pallidus internus (GPi) deep brain stimulation (DBS) with the AlphaDBS IPG System when programmed in adaptive versus conventional stimulating modes. It includes an initial open-label, crossover phase and a long term follow-up phase, during which the patient is free to switch between stimulating modes.
The aim of this study is to evaluate the role of different magnetic resonance sequences in demonstration of microstructural abnormalities in Parkinson's disease.
Postoperative delirium (POD) is a common complication, and the incidence of POD after deep brain stimulation(DBS) implementation ranges from 10% to 40%. Previous studies suggested that aging and existing non-motor symptom were independent risk factors for POD after supratentorial tumor resections. Therefore, patients undergoing DBS are high-risk populations for POD. A lot of trials show that dexmedetomidine might help to reduce the incidence of delirium in patients undergoing non-cardiac surgery. However, the impact of dexmedetomidine on POD for patients undergoing DBS was seldom reported. The purpose of this study was to investigate the effect of dexmedetomidine on POD in patients with Parkinson' Disease undergoing DBS.
This trial will study the safety and efficacy of intravenous infusion of cultured allogeneic adult umbilical cord derived mesenchymal stem cells for the treatment of Parkinson's Disease
Parkinson's disease (PD) is the second most common neurodegenerative disease and its prevalence is expected to double over the next 30 years, making it a leading cause of neurological disability [GBD 2016 Neurology Collaborators, 2019; Dorsey et al, 2018]. PD is characterized by motor symptoms, such as muscle stiffness, tremor, slowness of movement (bradykinesia) and postural instability, and non-motor symptoms, such as sphincter disorders, postural hypotension, cognitive disorders, depression, hyposmia, constipation and REM sleep behavioral disturbance. Unfortunately, the mechanisms leading to neuronal dysfunction and death in PD remain poorly known and there are currently no therapies capable of modifying their course [Bloem et al, 2021]. In this study we aim at defining a new set of biomarkers based on the combination between PET, blood metabolomics and natural language extracted from the keywords of electronic health records.
The purpose of this study is to evaluate the impact of a smartphone application that delivers at-home therapy exercises on patients' self-management of gait, speech, and dexterity symptoms.
