Brief Summary:
This study examines the safety and feasibility of DBS in treating the movement and cognitive dysfunction in Parkinson's disease (PD). Globus pallidus interna (GPi) stimulation is an established treatment for the motor symptoms in PD, but it does not treat the cognitive symptoms that can also be seen in this condition. It is theorized that we can improve cognitive dysfunction by stimulating a part of the brain called the nucleus basalis of Meynert (NBM), which releases a chemical (acetylcholine) and plays a role in memory and attention. By using a novel DBS system (Vercise device) with 2 electrodes that are designed to stimulate the GPi and NBM, we can potentially target the motor and cognitive symptoms of PD with a single intervention.
Detailed Description:
Neuronal loss within the cholinergic nucleus basalis of Meynert (NBM) correlates with cognitive decline in dementing disorders such as Alzheimer's disease and Parkinson's disease (PD). Deep Brain Stimulation targeting the Globus Pallidus interna (GPi) is an established treatment for the motor symptoms in Parkinson's Disease, and stimulating the NBM is believed to stimulate cognitive function. Targeting these two regions was previously impossible because they require different frequency stimulations, but recent developments in DBS technology allow for the dual stimulation of these nuclei at different frequencies.
This phase-II double-blind cross-over pilot trial will investigate the motor and cognitive effects as well as the presence of adverse effects of combined NBM and GPi DBS. The main goal of this pilot trial is to demonstrate the feasibility and safety of the multi-targeting approach in 6 patients with PDD and disabling motor symptoms.
