MRI Study Using 3T Scanner to Understand Brain Function in Patients With Deep Brain Stimulation for Neurological Disorders

What this Trial Is About

Researchers are investigating the effects of deep brain stimulation DBS on brain function in patients with various neurological and psychiatric disorders, including Parkinsons disease, essential tremor, dystonia, depression, epilepsy, neuropathic pain, and Alzheimers disease. This prospective cohort study aims to use advanced MRI techniques, particularly functional MRI fMRI, to better understand how DBS influences brain circuits and to explore whether fMRI can aid clinical practice in managing DBS therapy. Participants in this study include patients who will undergo or have already undergone DBS electrode placement. The study involves performing structural MRI scans using 1.5 Tesla or 3 Tesla machines as well as resting state and task-based fMRI scans. DBS patients will be scanned while their devices are programmed at different stimulation settings, including switched off and switched on states. The fMRI results will be shared with clinicians to help guide DBS programming decisions. During the study, participants will have multiple brain scans from three months before DBS implantation to one year after. Researchers will assess brain areas activated by DBS, examine structural and functional brain connectivity through MRI, and monitor clinical outcomes. The study includes regular evaluations to observe how DBS impacts brain function over time, aiming to improve post-operative follow-up and optimize treatment for these patients.
