Details and patient eligibility

About

The purpose of this Phase I open label study is to evaluate longer term tolerability and potential effectiveness of transcranial ultrasound in people with tremor as a results of Parkinson's Disease or Essential Tremor.

Full description

This study is designed to evaluate the safety and efficacy of focused ultrasound in patients with Parkinson's Disease or Essential Tremor characterized by tremor. The safety of this protocol will be closely monitored and data will be used to determine whether any significant safety issues exist when using focused ultrasound. Adverse events will be noted whenever they occur but will be recorded at the time of the procedure and throughout routine follow-ups, which will persist weekly throughout the duration of the active study protocol. Patients deemed potentially appropriate candidates for focused ultrasound therapy will be treated with 8 sessions of transcranial ultrasound, each of which consists of 10 to 30 minutes of active administration. Clinical and safety outcome measures will be obtained throughout and after completion of the study protocol.

Enrollment: 50 estimated patients

Sex: All

Ages: 18 to 90 years old

50 participants in 1 patient group

Experimental

Experimental group

Description:

Participants will undergo ten to thirty minutes of transcranial ultrasound treatment. The sanitation device will be aimed at the hypothalamus. Targeting will include reference to scalp fiducials based on the obtained MRI; confirmation of target accuracy will either be obtained by Doppler waveform confirmation or optical tracking technology which co-registers patient neuroimaging with real space.

Treatment:

Device: Focused Ultrasound
