Marcus has been referred to a clinical psychologist and has been diagnosed with schizophrenia. During his consultation, his father reported that Marcus regularly hears a voice providing a running commentary of his daily actions. Marcus also strongly believes that a local radio host is broadcasting his personal thoughts live to the public. Recently, Marcus has abandoned his favourite hobby of gardening, shows a complete lack of emotional response (flat affect) during conversations, and barely speaks, often replying in single-word answers. His father admits that he frequently sighs around Marcus, expresses severe disappointment in his career progress, and accuses him of being lazy.
