NCT07398157
The purpose of this study is to test a new way to treat Parkinson's disease (PD). Subjects will be implanted with deep brain stimulator (DBS) devices and electrodes placed under the scalp. The main questions it aims to answer are: * Is there a less invasive method to collect useful brain signals? Find out if these brain signals can be related to movement and/or sleep symptoms. * How to use these brain signals to tailor adaptive deep brain stimulation settings for movement and/or sleep symptoms Researchers will compare study derived adaptive DBS settings to subject's clinically programmed continuous DBS settings to see which is better at treating patients PD symptoms.
NCT07522138
This study aims to test whether patients with Parkinson's disease can safely and effectively use a home-based exercise program guided by videos. Participants will follow video instructions for exercises at home while their movements are monitored by a camera, which provides real-time feedback. The study will check how well participants complete the exercises, their satisfaction with the program, and any changes in clinical function. The goal is to see if this type of home exercise can help patients increase their activity levels without significant side effects.

Under regional anesthesia, subthalamic nucleus deep brain stimulation (STN-DBS) has proven to be an effective therapeutic approach for improving motor symptoms in Parkinson's disease. However, a significant portion of Parkinson's disease (PD) patients is unable to cooperate with the surgery, necessitating the use of awake sedation. Nevertheless, the administration of anesthetic drugs often impacts the electrical signals recorded by microelectrodes to varying degrees. This study is designed as a prospective, randomized, placebo-controlled, double-blind, two-arm investigation. PD patients scheduled for bilateral STN-DBS surgery will be randomly assigned to either the Dexmedetomidine group or the Dexmedetomidine combined with Esketamine group. The differences in neural activity between the two groups will be assessed using the normalized root mean square (NRMS) method. The primary outcome measure is NRMS, while secondary outcome measures include differences in beta oscillation power spectrum analysis, postoperative delirium incidence, postoperative changes in sleep disturbances, postoperative depression, anxiety status, and occurrence of adverse events.
NCT05895019
Propofol is a short-acting general anesthetic drug commonly used in clinical practice, with rapid clinical onset of action, amnesic, anxiolytic, antiepileptic, and muscle relaxant effects. The lack of natural antioxidants in patients with Parkinson's disease and propofol's ability to protect the brain by inhibiting oxidative stress, its pharmacokinetic and pharmacodynamic properties make propofol a suitable anesthetic drug for functional stereotactic surgery in patients with Parkinson's disease. However, changes in brain functional status during propofol anesthesia in Parkinson's patients are unknown. There is a lack of data from extensive clinical studies to support the need for propofol dosing during induction of anesthesia compared with non-Parkinson patients. This study is a prospective cohort study designed to compare the differences in propofol dosing requirements during induction of propofol anesthesia in patients with PD versus non-PD and to monitor the characteristics of altered brain functional status such as EEG and cerebral blood flow autoregulation capacity in PD versus non-PD patients during the perioperative period.
NCT05376761
Dexmedetomidine (DEX) sedation is widely used in deep brain stimulation implantation (DBSI) of patients With Parkinson's disease. However, intraoperative application of DEX may affect the discharge activity of deep brain nuclei and reduce the discharge frequency of Subthalamic nucleus (STN) neurons. At present, there is still a lack of prospective intervention research to explore the optimal dose that does not affect MER mapping in patients with Parkinson's disease. The present study uses the Dixon and Massey up-and-down method to analyze the EC50 of DEX in patients with PD undergoing STN-DBS sedation, to clarify the balance meets the sufficient comfort of patients without affecting the accurate target of MER and the optimal dosage of DEX for boundary recognition.
