Virtual reality cognitive training for ICU delirium survivors

Virtual Reality Cognitive Intervention for Critically Ill Delirium Survivors (VR-Cog)

Not applicable Interventional Indiana University · NCT07496255

This project will try virtual reality brain games at home to see if they help memory, attention, and mood in older adults who had delirium after a critical illness.

What this trial studies

This interventional pilot enrolls adults aged 50 and older who experienced acute respiratory failure and screened positive for ICU delirium; participants use a VR headset and hand controllers at home. The trial compares a VR-based cognitive training program to a VR-based attention-control program while measuring feasibility, acceptability, and adherence. Cognitive performance (memory and attention) and mood are measured before and after the intervention, with follow-up visits at the Indiana University Health site. Exploratory analyses will examine symptoms of depression and anxiety.

Who should consider this trial

Good fit: Ideal candidates are English-speaking adults aged 50 or older who were admitted to an ICU with acute respiratory failure requiring mechanical ventilation and screened positive for delirium, without pre-existing dementia or acute neurologic injury.

Not a fit: Patients with pre-existing dementia, severe chronic cognitive or sensory impairments, or acute neurologic injuries are unlikely to benefit and are excluded.

Why it matters

Potential benefit: If successful, the program could improve memory, attention, and mood and provide a scalable home-based therapy to reduce cognitive decline after ICU delirium.

How similar studies have performed: Some cognitive rehab and VR programs have shown promise in stroke and mild cognitive impairment populations, but VR for ICU delirium survivors is largely untested.

* Severe, uncorrected vision or hearing impairment preventing participation in intervention or outcomes assessments
* Admitted with acute alcohol or drug intoxication or withdrawal
* Severe, uncontrolled psychiatric disorder (bipolar disorder or schizophrenia)
* History of severe vertigo, motion-induced sickness, headaches, light sensitivity, seizures, or prior intolerance of virtual reality (VR)
* Receiving comfort care measures or not expected to survive the hospitalization
* Prisoners or patients unable to provide consent
* Not expected to be discharged home from the hospital, or living more than 50 miles from the nearest recruitment site, or homeless
