NCT ID: NCT06438419 Not yet recruiting - Parkinson Disease Clinical Trials

Parkinsonism-Related Oscillations in the Cortico-Basal Ganglia-Thalamic Network During Movement: Beyond the Frequency Range

MOVOSCILLCBGT
Start date: June 2024
Phase: N/A
Study type: Interventional

Expression of hypokinetic and hyperkinetic motor symptoms in Parkinson's disease (PD) is associated with pathological synchronous oscillations of neuronal activity (local field potential/LFP) in the cortico-subcortical network with a wide frequency range. In the present project, we propose to study cortico-subcortical oscillations and their synchronization in patients operated for PD (subthalamic deep brain stimulation (STN-DBS)) during distinct pharmacological and stimulation conditions (hypokinetic and hyperkinetic), using a simple motor task.

Mechanism and Application of DBS in the Treatment of PD

Start date: May 30, 2024
Phase: N/A
Study type: Interventional

Project name: The mechanism and application of deep brain stimulation in the treatment of Parkinson's disease Objective: To test the hypothesis that electrical stimulation of substantia nigra regulates cognitive dysfunction in Parkinson's disease and to reveal its electrophysiological mechanism. Study design: This study is a self-controlled prospective cohort study. By comparing the behavioral characteristics of the memory paradigm under microelectrode stimulation during DBS operation and the characteristics of the underlying electrophysiological signals, and the behavioral characteristics of the memory paradigm and the characteristics of brain network activity under electrical stimulation when DBS is turned on 1 month after surgery. The regulatory effect of substantia nigra DBS on memory network was analyzed. Cases: 60 Case selection: Inclusion criteria: 1)Voluntarily participate in the clinical study and sign the informed consent; 2) Age 50-70 years old, gender unlimited; 3) The clinical diagnosis is consistent with typical PD, and the medical history is less than 20 years; 4) Patients who intend to use 3.0T magnetic resonance compatible dual-channel DBS device (G106R or G106RS, Beijing Pinchi Company) for bilateral subthalamic nucleus DBS surgery to control PD symptoms; 5) MRI excluded patients with obvious structural changes; 6) The visual acuity and hearing of the subjects were basically normal, and the compliance was good, and they could complete the tasks listed in the experimental scheme in accordance with the standards. Exclusion criteria: 1)Serious mental, cognitive and psychological disorders, unable to sign informed consent or cooperate with the operation and various tasks; 2) There are contraindications for neurosurgery, such as hydrocephalus, cerebral atrophy, cerebrovascular sequelae, heart disease and other cardiovascular and cerebrovascular diseases; 3) There are concomitant diseases that seriously affect health, such as tumors, serious abnormalities of liver and kidney function (indexes more than 3 times normal); 4) There is intracranial space occupation, cerebrovascular disease, mental illness, other neurological diseases, claustrophobia, or there is an implant in the body, which affects the nuclear magnetic scan; 5) The results of the Mini-Mental State Scale (MMSE) <24 or the Montreal Cognitive Assessment Scale (MoCA) <18 in the preoperative assessment, or the results of other scales indicate the presence of severe dementia. therapeutic scheduleļ¼š This study did not change the patient's overall treatment regimen, and only electrical stimulation was tested during and 1 month after DBS surgery Efficacy evaluation: Effectiveness evaluation index (primary efficacy index and secondary efficacy index) : accuracy of memory paradigm, response speed Safety evaluation indicators: blood pressure, heart rate, dual frequency index, patient complaints and symptoms Statistical methods: The group t test was used to compare the normal distribution between the measurement data groups. For measurement data with non-normal distribution, Wilcoxon rank sum test was used for comparison between groups. The study period is January 1, 2024 - December 31, 2026.

NCT ID: NCT06350617 Recruiting - Clinical trials for Parkinson's Disease and Parkinsonism

Personalized rTMS Protocol Based on Functional Reserve to Enhance Ambulatory Function in PD Patients

Start date: February 20, 2024
Phase: N/A
Study type: Interventional

The objective of this study was to determine the effects of protocols of repetitive transcranial magnetic stimulation (rTMS) therapy based on the functional reserve of each patient with Parkinson's disease, compared to conventional high-frequency rTMS therapy on bilateral primary motor cortex (M1). Investigators hypothesized that the functional reserve of each patient with Parkinson's disease will be different, and therefore an appropriate simulating target for rTMS therapy is needed. In addition, this approach could be more effective compared to conventional protocols applied to patient with Parkinson's disease regardless of their severity, predicted mechanism of motor function recovery, or functional reserves.

NCT ID: NCT06272968 Not yet recruiting - Clinical trials for Cognitive Impairment

Predicting Cognition After DBS for Parkinson's Disease 2

Start date: February 25, 2024
Phase:
Study type: Observational

The aim of the study is to improve estimation of cognitive outcome after STN-DBS in PD in order to avoid risk factors by optimizing peri- and intraoperative management personalize therapeutic strategies for optimal long-term benefit. The investigators will test possible predictors (clinical, neuropsychological, neuroimaging, electrophysiological and molecular) for the risk of cognitive dysfunction after deep brain stimulation of the subthalamic nucleus (STN-DBS) in Parkinson's disease (PD) at a single center (Charité - Universitätsmedizin Berlin, Germany). Data collection takes place prior to as well as 3, 12 and 60 months after the STN-DBS operation. Participation is proposed to all PD patients that are planned to undergo STN-DBS after careful examination of eligibility for this treatment according to standard operation procedures.

NCT ID: NCT06247423 Recruiting - Nerve Block Clinical Trials

High-frequency Alternating Current Stimulation for Tremor in Parkinson's Disease.

Start date: February 2, 2024
Phase: N/A
Study type: Interventional

The goal of this randomized, double-blind, placebo-controlled, crossover study is to test the effectiveness of 10 kilohertz (kHz) high-frequency transcutaneous stimulation for tremor in people with Parkinson's disease. The main questions it aims to answer are: - Compare the effectiveness between sham stimulation and real stimulation (10kHz) for different types of tremors [rest tremor, postural tremor, kinetic tremor], fine motor skills, and maximal isometric handgrip strength. - Register adverse events, the blinding success of participants and evaluator, and subjective perception of tremor improvement. Participants will perform the following tasks in an "off" state (without levodopa and dopamine agonists medication). All of them were performed on the upper limb with more tremor. - Rest Tremor: Forearm on the armrest, count backward from 100 to 0 as fast as possible for 1 minute and 30 seconds. - Postural Tremor: Extend the arm parallel to the floor (90º shoulder flexion with the forearm extended) for 30 seconds. - Kinetic Tremor: Hold a cup by the handle, raise it close to the mouth for 3 seconds, then return to the initial position. - Fine Motor Skills: Complete the nine-hole peg test, placing pegs into holes as quickly as possible. - Handgrip Strength: Squeeze the device as strongly as possible for 3 seconds, then rest for 15 seconds.
