Inflammatory and Genetic Predictors of Cognitive and Emotional Recovery After Critical Illness (CORE-ICU)
Unraveling the Role of Cognitive Reserve, Inflammatory Phenotype and Genetic Vulnerability on Cognitive and Emotional Recovery After Critical Illness
Survivors of critical illness frequently develop persistent cognitive and emotional impairments, known as post-intensive care syndrome (PICS), which substantially impact quality of life and long-term recovery. While prior research has mainly focused on identifying risk factors, the mechanisms underlying resilience to these sequelae remain poorly understood. Emerging evidence suggests that biological factors, including inflammatory responses and genetic vulnerability, together with cognitive reserve, may play a key role in shaping recovery trajectories.
The aim of this multicenter, prospective observational study is to investigate how cognitive reserve, inflammatory phenotype, and genetic profiles interact to influence cognitive and emotional recovery after critical illness. Adult patients will be recruited at Intensive Care Unit (ICU) admission across two centers in Spain. Clinical and sociodemographic data will be collected during the ICU stay, and biological samples obtained early after admission will undergo transcriptomic and genetic analyses. Cognitive and emotional outcomes will be assessed at hospital discharge and at 3 and 12 months post-discharge using standardised neuropsychological and telemedicine-based evaluations.
By integrating clinical, biological, and cognitive data, this study seeks to identify recovery phenotypes and resilience mechanisms in PICS. The results may contribute to improved risk stratification, inform personalized interventions, and support the development of future strategies aimed at reducing the long-term burden of critical illness.
