Marcus has been diagnosed with schizophrenia. He reports hearing whispering voices coming from the walls of his flat, and is convinced that local police have implanted a tracking microchip in his shoulder to monitor his movements. Marcus has stopped washing his clothes, rarely leaves his room, and speaks only in a slow, monotonous whisper with no variation in tone.
In the past, Marcus has refused to take his prescribed oral medication because he feared that his previous care team was trying to poison him. However, Marcus's current clinician is certain that a biological treatment is the most appropriate next step to manage his symptoms.
