Official title: Virtual Reality-Based Cognitive Stimulation Games for Enhancing Attention and Preventing Delirium in Older Surgical Patients With Cognitive Impairment

Run by The Methodist Hospital Research Institute · NCT07641153 · Data updated 2026-11-12

A VR-based cognitive stimulation game is being tested to see if it can help prevent delirium in adults 65 and older after major surgery.

Is this trial a fit for you?

Likely a good fit

Adults aged 65 and older with pre-existing cognitive impairment (MoCA 15-24) who undergo major surgery and are expected to require ICU care for at least three days.

Probably not a fit

Patients without pre-existing cognitive impairment, those not expected to require ICU admission, or those with contraindications to VR stimulation may not benefit.

What this trial studies

This pilot randomized trial tests the feasibility, safety, and acceptability of a virtual reality (VR) cognitive stimulation program for high-risk older adults after major surgery. Participants are randomized to one of three arms: VR-based cognitive games, VR movie viewing, or nurse-led reality orientation. The study will look at cognitive function, especially sustained attention, and the incidence of postoperative delirium. Enrolled patients are 65 years or older with pre-existing cognitive impairment and expected ICU admission for at least three days after surgery. The trial is conducted at Houston Methodist facilities with collaboration from the National Institute on Aging.

Why it matters

Potential benefit: If successful, the VR-based approach could reduce delirium risk and improve postoperative cognitive outcomes for high-risk older patients.

How similar studies have gone: Previous non-pharmacologic cognitive interventions show promise, but VR-based CS delivery for delirium prevention in this population is exploratory.
