Study Arms:
- Active (Type: ACTIVE_COMPARATOR): Participants will be receiving an active Caloric Vestibular Stimulation treatment for a duration of 8 weeks, 7 days a week, twice daily for 19 minutes.
- Placebo (Type: SHAM_COMPARATOR): Participants will be receiving a Sham Caloric Vestibular Stimulation treatment for a duration of 8 weeks in the same manner as the active arm: 7 days a week, twice daily for 19 minutes.~Individuals allocated to this arm will be later crossed over, in unblinded fashion, to the active arm if the treatment shows evidence of efficacy and safety.

Based on this trial design, predict the completion outcome and termination type (if applicable).
