Why some ICU survivors recover mentally better than others: scientists investigate
NCT ID NCT07659431
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at why some people recover their thinking and emotional skills better than others after a serious illness requiring intensive care. Researchers will follow 114 adults admitted to ICUs in Spain, collecting blood samples and testing memory, attention, and mood at discharge and up to a year later. The goal is to understand how factors like cognitive reserve, inflammation, and genetics influence recovery, which could lead to better support for survivors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could help identify patients at risk for long-term cognitive problems after ICU stays and guide personalized recovery plans.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly test any therapy. The findings may not apply to all ICU survivors.

Inclusion Criteria: * Adult patients (≥18 years) * Admitted to a medical-surgical ICU or cardiac ICU for causes of critical illness (e.g., acute pulmonary oedema, myocardial infarction, aortic dissection) * With or without the need for invasive mechanical ventilation * With an expected ICU stay of ≥48 hours * Resident in Catalonia or the Principality of Asturias * Who speak Catalan and/or Spanish * Who are able to provide informed consent personally or through an authorised representative (e.g., a family member) Exclusion Criteria: * Non-authorisation by the patient and/or relatives for inclusion in the study * Patients admitted to a neurocritical ICU * History of severe neurological disease (including dementia or focal brain injury with functional and cognitive impairment) prior to ICU admission * History of severe psychiatric disorders (schizophrenia, bipolar disorder, major depressive disorder) * Intellectual disability (IQ \<80) or other neurodevelopmental disorders, such as autism spectrum disorder * Patients who develop secondary complications (e.g., infections, stroke, traumatic brain injury, or other non-transient acquired brain injury) after ICU discharge that may compromise the results of emotional and neuropsychological evaluations during the recovery phase * Moderate to severe cognitive impairment (Short-IQCODE \>57) preventing independent participation in telemedicine or face-to-face follow-up * Readmission to the ICU within 12 months after ICU discharge * Language barrier (non-Spanish- and/or non-Catalan-speaking patients) * Patients with a life expectancy \<1 year or not eligible for active treatment measures
