We are seeking volunteers who are 18-65 years of age for a research study of EEG-guided medication treatment for depression. Participants must be a patient at a participating study site or a new patient interested in establishing care with one of our participating providers. Participants will be evaluated for eligibility by their provider. Study participation may last 6 months or longer. Study procedures will occur during patient care, and visits will be filed with insurance. Study-specific procedures will not be an additional cost to participants. Though participation may or may not improve personal outcomes from medication, it will aid in evaluation of a new technology seeking to improve treatment for active duty service members, veterans, their families, and the larger community. If you are interested in participating, please contact Jessie Robertson, our Clinical Research Coordinator, by calling (828) 254-9494 or emailing jrobertson@pisgahinstitute.com.
