The primary objective of this randomized study is to evaluate the effect of a virtual reality (VR) video on pre-treatment anxiety levels in individuals undergoing magnetic resonance-guided focused ultrasound (MRgFUS) treatment for medication-refractory essential tremor (ET). Participants will be randomized to view one of two VR videos, and pre-treatment anxiety levels will be compared between groups. As a secondary objective, the study will compare patient concerns (including claustrophobia, mental preparedness, and fear of pain, as well as any additional concerns identified during the study) between the two randomized groups.
