Investigating Central Neurophysiologic Correlates of Non-Motor Symptoms of Parkinson's Disease
In Brief
A clinical study evaluating transcranial magnetic stimulation for Parkinson Disease and 2 related conditions. Completed, enrolled 30 participants across 1 site.
Detailed Summary
This is a randomized, single-blinded, triple crossover study focused on determining the feasibility of using transcranial magnetic stimulation (TMS) for treatment of Parkinson's disease related autonomic dysfunction and depression. Participants will undergo TMS to three brain regions: medial prefrontal cortex (mPFC) (experimental site), dorsolateral prefrontal cortex (DLPFC) (alternative experimental site), or primary sensory cortex (S1) (control site) in a triple crossover design. Participants will complete symptom questionnaires, neurologic examination and cognitive assessments, and orthostatic vital signs recording before and after each brain stimulation session.

Timeline
Interventions
Transcranial magnetic stimulation (or TMS) is a non-invasive form of brain stimulation in which a magnetic pulse is applied directly to the scalp. This device is FDA approved for treatment of depression and other neuropsychiatric disorders, and is regularly used in neurologic and psychiatric research. iTBS is a particular TMS protocol which delivers the magnetic field in triplet bursts (three stimulations very close together at a frequency of 50 Hz very quickly). The triplet bursts are repeated at a rate of 5 Hz for 2 seconds (30 pulses), followed by 8 seconds rest, repeated 20 times for a total of 600 pulses. Each treatments lasts approximately 3 minutes.
