It's hard to pin it down to a single drug. Having had both my grandmother (80) and mother (60) in the ICU, and both got hallucinations without Ativan. It could be so many things: * The aftermentioned lack of sound sleep * Anesthesia * Painkillers In the case of my grandmother, hallucinations and incoherence lasted about three months after she was home. My mother's lasted about 2-3 weeks. It was scary. They both eventually recovered. But it is true that nobody in the hospital bats an eye when acute dementia-like symptoms are mentioned. "It's normal," they say.
