Chloe is concerned that her brother, Marcus, may have a mental disorder. Marcus has started wearing all his clothes inside out and backwards to "block tracking signals". He has also stopped attending his university lectures and missed his end-of-term exams because he believes the lecture halls are wired with wireless listening devices.
Marcus will only drink bottled water that he has boiled three times. He refuses to sleep at night, instead spending those hours patrolling his backyard with a flashlight, which has left him too exhausted to turn up for his part-time job.
Discuss the diagnosis of mental disorders in terms of deviance and dysfunction. You must make reference to the context in your answer.
