From delirium to posttraumatic stress disorder: A systematic review

Evidence is heterogeneous and does not support delirium as a uniformly traumatic exposure. Delirium may be relevant for PTSD outcomes in a subset of patients-particularly when perceived threat is high and memory integration is disrupted-within the broader context of severe illness and intensive care. Clinically, delirium prevention, trauma-informed care, and targeted follow-up screening after severe, prolonged or distressing delirium episodes appear warranted.
