ABSTRACT
A 65-year-old woman was found wandering the streets in a confused and agitated state, so passers-by called for an ambulance. The person was unable to give a thorough history. Her neighbours informed the paramedics that she was usually fit and well, although her medical history was significant for bipolar affective disorder, for which she takes lithium. Her other regular medications are ramipril and bendroflumethiazide for hypertension. She lives alone and attends a drop-in community mental health centre in addition to regular visits by a community psychiatric nurse and a friend. She denies smoking or alcohol intake.
