The ICU environment paradigm as a catalyst for better delirium models

Key Points

The aim is to improve delirium models in animals by incorporating ICU-like environmental stressors.
Combined surgery or sepsis with light, noise, sleep disruption, and handling in models.
Emphasized the relevance of environmental stressors to mimic human ICU conditions.
Enhanced translational validity of animal models for human ICU delirium.
Circadian disruption identified as a key area for future mechanistic investigation.

Abstract

Abstract The present commentary argues that incorporating ICU-like environmental stressors into animal delirium models improves translational validity. By combining surgery or sepsis with light, noise, sleep disruption, and handling, the discussed paradigm better reflects human ICU delirium, supports mechanistic discovery, and highlights circadian disruption as a promising framework for future investigation.
