anxiety
"My elderly dad was prescribed a low dose of Ativan for anxiety. Within 2 weeks he started having auditory hallucinations and could not sleep because the "walls were talking to him". After he passed every physical test in an emergency visit to the local ER- from a cat scan to blood work and everything in between, the psychiatrist on duty matter of factly told me that Ativan has been known to cause delirium in elderly patients.
