ABSTRACT
A 52-year-old man was brought to hospital after being found wandering in a state of distress by concerned passers-by. He described feeling disorientated and aware of a threat to his safety, although he was unable or unwilling to elaborate further. He said that his past medical history included bipolar affective disorder and hypertension. He took 350 mg lithium carbonate (modified release formulation) OD and had recently commenced 2.5 mg bendroflumethiazide OD to treat his newly diagnosed hypertension. He lived alone and worked part-time in a consultancy firm. He denied drinking alcohol and had never smoked. He had previously attended regular community mental health drop-in sessions but said that he no longer did so as his bipolar affective disorder had been stable for years.
