Symptoms
Martin is a 21 year-old business major at a large university.
Over the past few months his family and friends have noticed
increasingly bizarre behaviours. On many occasions they’ve
overheard him whispering in an agitated voice, even though
there is no one nearby. Lately, he has refused to answer or
make calls on his cell phone, claiming that if he does it will
activate a deadly chip that was implanted in his brain by evil
aliens.
He has accused his family on several occasions of conspiring
with the aliens to have him killed so they can remove his brain
and put it inside one of their own. Martin frequently breaks
down in tears when he confronts his family of conspiring with
the aliens to have him killed. He doesn’t understand why they
want to hurt him.
He has stopped attended classes altogether. He is now so far
behind in his coursework that he will fail if something doesn’t
change very soon.
