Parkinson's Disease Clinical Trials in Stanford, CA

The goal of this clinical trial is to evaluate the safety and tolerability of a novel deep brain stimulation (DBS) of the Subthalamic Nucleus (STN) and Nucleus Basalis of Meynert (NBM) to treat cognitive and cognitive-motor symptoms in individuals with Parkinson's disease. The main question it aims to answer is: Is a combined deep brain stimulation approach targeting the STN and NBM with four DBS leads safe and tolerable for cognitive and cognitive-motor symptoms in individuals with Parkinson's disease with Mild Cognitive Impairment. Ten participants are anticipated to be enrolled. Participants will undergo a modification of the traditional STN DBS approach for motor symptoms of PD. In addition to the two leads placed within the STN, two additional leads will be placed with the NBM for treatment of cognitive and cognitive-motor symptoms. Novel stimulation patterns will be used within the NBM to target cognitive and cognitive-motor symptoms using an investigational software. Participants will be followed over two years while receiving this therapy with assessments at baseline and every six months. Assessments will include a combination of neuropsychological evaluations, cognitive assessments, motor tasks (including gait/walking), and questionnaires to evaluate the treatment. Two different surgical trajectories will be used, with half the cohort randomized to each group. This will allow comparison of the impact of surgical trajectory on the intervention. Read Less

This is a Phase 1/2 study to evaluate the safety and tolerability of 18F-OP-801 in subjects with ALS, AD, MS, PD and age-matched HVs. 18F-OP-801 is intended as a biomarker for PET imaging of activated microglia and macrophages in regions of neuroinflammation. Read Less

Deep Brain Stimulation of the subthalamic nucleus (STN) has become a standard of care, FDA-approved treatment for Parkinson's disease, with stimulation delivered at a constant amplitude and voltage, operating in an open-loop fashion that does not respond to a patient's current state. Although gait deficits and freezing of gait may initially respond to continuous open-loop deep brain stimulation (olDBS) and medication, the symptoms often recur over time. The episodic and predictable nature of FOG makes it well suited for adaptive DBS (aDBS) and a device that overcomes the limitations of traditional high frequency olDBS and is capable of adapting therapy either in the frequency or intensity domain transiently to treat FOG while also treating other PD signs such as tremor and bradykinesia. The purpose of this study is to determine the feasibility of an adaptive DBS system, that responds to patient-specific neural and kinematic variables with customized DBS parameters. Read Less
