title: Acute mental status changes caused by propranolol.
abstract: A 74-year-old woman with mild dementia became disoriented and developed paranoid delusions when treated with low-dose propranolol. There was no evidence of cardiovascular instability, and the symptoms resolved within a week. Rechallenge with propranolol led to a recurrence of mental status changes.
