Outcome Measures
Primary Outcomes (4)
Cerebral Blood Flow (CBF) Perfusion
Cerebral blood flow (CBF) measured using pseudo Continuous Arterial Spin Labeling (pCASL) magnetic resonance imaging (MRI) will be used to monitor changes in global perfusion
baseline
Cerebral Blood Flow (CBF) Perfusion

end of treatment (week 12)
Cerebrovascular Reactivity
Cerebral blood flow is measured with pCASL MRI at baseline and during hypercapnic challenge. The percent change in CBF is divided by the increase in end-tidal CO2 measured in mmHg, measured with RespirACT system

Study Arms (2)
Treatment 1
EXPERIMENTALParticipants will receive Experimental treatment 1 stimulation for a duration of 12 weeks, twice daily for 19 minutes
Treatment 2
EXPERIMENTALParticipants will receive Experimental treatment 2 stimulation for a duration of 12 weeks, twice daily for 19 minutes
Interventions
Study participants will self-administer \~19-minute treatments twice daily in the home setting using a non-invasive brainstem modulation device. The device has been deemed as a nonsignificant risk for studies in Parkinson's disease by the United States Food and Drug Administration.
