Condition: Parkinson Disease, Idiopathic · Sponsor: University of Florida
Nearly one-million people in North America are now living with Parkinson's disease (PD), and that number is projected to rise to nearly 1.2 million by 2030. With advancements in neuromodulatory technologies, increasingly more of these individuals elect to undergo deep brain stimulation (DBS) surgery in order to control symptoms of the disease, including refractory tremor, medication-induced dyskinesias, and PD-associated dystonia. The two most common DBS neural targets for controlling these symptoms are the globus pallidus internal segment (GPi) and the subthalamic nucleus (STN). Recent meta-analyses have shown relative equivalence between these two sites at controlling core PD symptoms. To date, there is not conclusive evidence regarding the potential impact of DBS to GPi or STN on laryngeal-mediated functions of voice, swallowing, and cough, and consequently no guidance on whether these outcomes should be considered when selecting DBS target. Therefore, the goal of this project is to determine the impact of DBS neural target (STN versus GPi), lead location within the target, laterality, and stimulation settings on voice, swallow and cough function in people with PD. The larynx is an important player in each of these functions, and our central hypothesis is that spread of stimulation to corticobulbar fibers in the genu of the internal capsule have deleterious effects on laryngeal motor control, resulting in voice, swallow, and cough dysfunction. We have identified three spec…
