Outcome Measures

Primary Outcomes (1)

  • behavioral task performance

    Participants will complete behavioral tasks at each of three visits to assess the effects of stimulation settings on task performance. At each research visit, behavior will be assessed beginning at 1 hour after the stimulation is adjusted to the experimental settings. Stimulation settings will be returned to each patient's treatment levels at the culmination of each visit.

    1 to 2 hours

Study Arms (1)

Deep Brain Stimulation

EXPERIMENTAL

Parkinson's patients with deep brain stimulation in the subthalamic nucleus.

Procedure: Stimulation of the subthalamic nucleus

Interventions

Stimulation is delivered to the subthalamic nucleus at experimentally prescribed settings.

Deep Brain Stimulation

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participants diagnosed with idiopathic Parkinson's disease that meet criteria for treatment of their disease with STN-DBS. Participants will be selected for this study without regard for age (provided they are older than 18), gender or ethnic background.
  • Participants must have undergone subthalamic nucleus DBS surgery and be receiving treatment at the Scripps Clinic in La Jolla, CA

You may not qualify if:

  • Patients under 18 years old.
  • Patients with mini-mental status scores below 26/30.
  • Patients with known psychiatric disease.
  • Patients who are too infirm, demented or dysarthric to clearly understand the consenting process, task instructions, or to communicate verbally regarding participation or non-participation.
