Four Distinct Dynamic Intracranial Pressure Trajectories and Their Prognostic Implications in Acute Brain Injury: A Multicenter Cohort Study

CNS Neuroscience &Therapeutics, Volume 32, Issue 1, January 2026.
Across a multicenter ICU cohort (n = 1700), latent‐class modeling of 0–120 h ICP identified four trajectories. Severe progressive and stabilized‐elevated patterns carried the greatest mortality risk (HR 13.54 and 2.53), with mildly elevated‐stable showing modest risk (HR 1.48).
