Bringing the Outdoors In: Virtual Nature Walks for Depression in Multiple Sclerosis (MS) Patients

Summary

This trial explores the use of immersive virtual reality (VR) nature-based experiences as a supplementary treatment for depression in individuals with progressive multiple sclerosis (MS). This study will evaluate the feasibility and efficacy of at-home VR deployment using the Apple Vision Pro, an advanced device that offers enhanced resolution, immersion, and usability compared to earlier VR systems. The study hypotheses include: * The integration of VR nature-based experiences with standard care will be feasible, acceptable, and will result in greater reductions in depressive symptoms compared to standard care or VR-only interventions. * The integration of VR nature-based experiences with standard care will result in greater reductions in stress and anxiety, better sleep, less insomnia, and improved fatigue compared to standard care alone or VR-only interventions.

Eligibility

Inclusion Criteria:

* Confirmed diagnosis of progressive Multiple Sclerosis (MS, primary or secondary) by a neurologist or an MS center
* Patient-Reported Outcomes Measurement Information System (PROMIS) Depression T-scores \>55 at baseline
* Ability to provide informed consent and participate in VR sessions at home
* For Some Participants (Groups 1 and 2) currently receiving antidepressant or psychotherapy treatments (Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs), or psychotherapy) for the management of depression

Exclusion Criteria:

* Severe cognitive impairments or visual deficits that may interfere with VR use, including contraindications like agoraphobia, claustrophobia, or motion sickness
* Current participation in other clinical trials targeting depression
* Severe psychiatric conditions that require hospitalization, or suicidal ideation, passive or active, psychosis, or active substance and alcohol abuse (score greater than 1 on CAGE (Cut down, Annoyed, Guilty, Eye-opener) Adapted to Include Drugs (CAGE-AID))
* Another neurological or autoimmune disease per protocol
* Participants that require vision correction, unless that vision correction is mild (± 1), or the participant has prescription contact lenses.
