Overview
The purpose of this study is to measure the feasibility, acceptability of virtual reality (VR) brain games and estimate their effect on memory, attention, and mood for ICU survivors. The VR program will be used at home through a headset and hand controls.
Description
Acute respiratory failure (ARF) accounts for 2 million admissions to adult intensive care units (ICUs) in the United States annually, and up to 80% of older adults with ARF suffer delirium, a form of ICU-related acute brain dysfunction. Delirium doubles the risk for new cognitive impairment or dementia within 12 months of ICU discharge. In addition, delirium survivors frequently develop related mental health and quality of life impairments. Unfortunately, there are few effective or scalable interventions to improve cognitive outcomes for ICU survivors.
Primary Objective Aim 1: Measure the feasibility, acceptability, and adherence of VR-Cog in older adult ICU delirium survivors at risk for ICU-acquired MCI and ADRD.
Secondary Objective Aim 2: Estimate the effect of VR-Cog on cognitive performance among older adult ICU delirium survivors.
Tertiary/Exploratory/Correlative Objectives Aim 3: Explore the effects of VR-Cog on mental health (depression and anxiety).

- 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
