Brief Summary
Parkinson's disease (PD) patients treated with deep brain stimulation (DBS) of the subthalamic nucleus (STN) have unpredictable and varied speech outcomes after this treatment. Our research will prospectively document speech performance before, during and 6- and 12-months after STN-DBS in 80 surgically treated patients and compared with 40 non-surgical controls with Parkinson's disease. This study will provide unique insights into the role of STN in speech production, document speech outcome in a comprehensive fashion, identify factors that predict functional communication ability 12 months after STN-DBS, and test the feasibility of low frequency DBS in reversing DBS-induced speech declines in order to optimize treatment strategies for those living with Parkinson's disease.

Outcome Measures
Primary Outcomes (1)
Neuron Firing Rate
DBS-STN participants will complete simple speech and motor tasks during surgery while the surgeon records neuron firing rate using Microelectrode Recording (MER).
Intraoperatively
Secondary Outcomes (2)
Speech Intelligibility with DBS ON
Speech intelligibility with DBS ON will be measured at the 6 month follow up and 12 month follow up for the DBS-STN group.
Speech Intelligibility (stimulation OFF or not applicable)
Speech intelligibility without stimulation will be measured at baseline, 6 month, and 12 month visits for all participants.
Study Arms (2)
DBS-STN
The DBS-STN group will consist of individuals with Parkinson's disease who have already elected to undergo deep brain stimulation surgery.
Control
The control group will consist of individuals with Parkinson's disease who are not undergoing deep brain stimulation placement. No interventions will be completed with the control group.
Eligibility Criteria
We will recruit 80 STN-DBS participants and 40 participants with Parkinson's disease to serve as non-surgical controls. All Parkinson's disease patients judged to be candidates for DBS surgery by the implanting neurosurgeon and movement disorder neurologists who decide to undergo bilateral surgery will be considered candidates for the study. Control subjects must have a diagnosis of Parkinson's disease and no plan to undergo DBS surgery.
You may qualify if:
- have a confirmed diagnosis of idiopathic Parkinson's disease and no atypical Parkinsonism features
- experience significant motor fluctuations
- currently taking and responsive to dopaminergic medications (e.g. Levodopa)
- use English as their primary language
- lack significant cognitive impairment and be able to consent to participate
You may not qualify if:
- Significant hearing loss/reliance on hearing aids
