MSFinals-5402

A patient in their 50s is brought to the acute mental health unit by the police after being found on the street shouting at people. They have no known past medical history.

On examination, they are poorly dressed. When asked about their mood, they begin by asking what colour the sky is, then begin to talk about their strong dislike for cheese, followed by wanting to break the table lamp they own at home. Throughout the consultation, they speak slowly.
