I just watched the movie "Shutter Island". Leonardo DiCaprio stars as US Marshal Edward Daniels who is insane. He killed his wife after she killed their three children. Teddy Daniels (who is actually Andrew Laeddis) developed Delusive Personality Disorder (previously known as Paranoid Personality Disorder) as a defense mechanism and a way to supresing his memory of trauma. Insanity is a way to escape from painful reality and from overwhelming guilt, so affected person developes alternative reality through several delusions. There are bizarre and non-bizarre delusions. Teddy Daniels is developing a non-bizarre delusions. Non-bizarre delusions typically are not out of the realm of possibility. Bizarre delusions are completely impossible. As an alien abduction. So, there is the difference between bizarre delusions (Schizophrenia), and non-bizarre delusions (Delusional disorder: persecution, poisoning...).
The movie is excellent. What I want is to separate art from reality.
Is the manifestation of mental illness equal to the severity of trauma? If someone has experienced severe trauma he will develop a serious mental illness.
Has anyone seen the movie? If so please join the discussion.
