Summary

The study will test the feasibility of using Low Intensity Focused Ultrasound Pulsation (LIFUP) to treat motor symptoms in Parkinson's Disease (PD). LIFUP is a new technique that can increase brain activity in highly specific target areas and is MRI compatible. Thus, in real-time, it is possible to directly observe how LIFUP changes the brain areas important in PD by measuring its effects on brain activity, blood flow, and brain connectivity. If successful, this research will mark the first step towards a novel, non-invasive, non-medication treatment for PD.

Conditions

  • Parkinson Disease

Interventions

DEVICE

Active LIFUP Treatment

Low intensity focused ultrasound pulsation will be administered to the internal globus pallidus in 20 sonications at 650kHz, ispta.3 720mW/cm, pulse repetition frequency 100Hz, duty cycle 5%, duration 30s with 30s spacing between sonications. For active LIFUP, the device will be used with a gel pad that allows the ultrasound to pass through.

DEVICE

Sham LIFUP Treatment

The device will be aimed at the internal globus pallidus and turned on with the same settings as the active condition; however, in this case, the device will be used with a gel pad that blocks the ultrasound from passing through, such that no ultrasound is actually being administered to the brain.
