What this trial studies

This study evaluates the effectiveness of computerized cognitive rehabilitation for patients who have experienced long-term cognitive impairment after surviving an intensive care unit (ICU) stay. The intervention aims to harness neuroplasticity to improve cognitive function and brain structure in patients suffering from post-ICU long-term cognitive impairment (ICU-LTCI). A total of 160 participants will be randomized to receive either the cognitive rehabilitation or an active control involving computer games. The study is designed to address a significant unmet need in the rehabilitation of ICU survivors, particularly among veterans.

Who should consider this trial

Good fit: Ideal candidates are adults who have recently stayed in an ICU for respiratory failure or shock and no longer require ICU-level care.

Not a fit: Patients with severe pre-existing cognitive impairments or those unable to participate in computer-based training may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve cognitive function and quality of life for ICU survivors.

How similar studies have performed: Previous studies have indicated the potential for cognitive rehabilitation approaches to improve outcomes in similar patient populations, suggesting this intervention may build on established findings.
