Summary
In Parkinson's disease (PD) patients undergoing standard-of-care Deep Brain Stimulation (DBS) therapy, to compare the effect on Parkinson's symptoms of two different neurostimulator settings designed to differ from each other as much as possible with respect to how much they activate two different neuroanatomical structures: the axonal pathway from Globus Pallidus (GP) to Pedunculopontine Nucleus (PPN), and the axonal pathway from PPN to GP.
Description
In Parkinson's disease (PD) patients undergoing standard-of-care Deep Brain Stimulation (DBS) therapy, to compare the effect on Parkinson's symptoms of two different neurostimulator settings designed to differ from each other as much as possible with respect to how much they activate two different neuroanatomical structures: the axonal pathway from Globus Pallidus (GP) to Pedunculopontine Nucleus (PPN), and the axonal pathway from PPN to GP. In this respect, the present protocol is similar to Protocol STUDY00008644. In fact, that protocol, and this one, cover different Aims of the same NIH-fun…

- Healthy volunteers
- No
* Diagnosis of Parkinson's Disease * Bilateral DBS in STN or GP * At least 3 months after lead implantation * Montreal Cognitive Assessment (MoCA): MoCA=23+ OR: If MoCA score is 23 or less, UBACC will be performed to ensure capacity to consent. If UBACC results are unclear, the MacCAT-CR will be performed. Failed or unclear MacCAT-CR results will exclude the study candidate. * Between 18-85 years of age * Has undergone pre-operative 7T MRI (as part of protocol #1210M22183 or standard-of-care) and post-operative CT imaging (standard of care). 8.2 Exclusion Criteria: * Inability to walk in…
