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

    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

    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

    baseline

  • 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

    end of treatment (week 12)

Secondary Outcomes (1)

  • Percent Change in Functional Connectivity

    baseline and end of treatment (week 12)

Other Outcomes (14)

  • Change in Cerebral Haemodynamics

    baseline and end of treatment (week 12)

  • Durability of Change of Cerebral Blood Flow (CBF) Perfusion

    baseline and the post-treatment follow-up (week 17)

  • Durability of Change of Cerebrovascular Reactivity

    baseline and the post-treatment follow-up (week 17)

  • +11 more other outcomes

Study Arms (2)

Treatment 1

EXPERIMENTAL

Participants will receive Experimental treatment 1 stimulation for a duration of 12 weeks, twice daily for 19 minutes

Device: Non-invasive brainstem stimulation

Treatment 2

EXPERIMENTAL

Participants will receive Experimental treatment 2 stimulation for a duration of 12 weeks, twice daily for 19 minutes

Device: Non-invasive brainstem stimulation

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.
