Diagnosis and Treatment
In the movie A Beautiful Mind, Russell Crowe plays as John Nash; an incredibly intelligent man with an abnormal personality and opposition for people. The movie starts with Nash attending Princeton college in 1945 where he later attempts to make a very large breakthrough in mathematics. He appears to be highly stressed and tends to stray away from others. John's expressions are at times inappropriate and quite frank, he says what comes to mind no matter how it may come across or be perceived. He understands that he does not possess an inviting personality and has no problem with it. John is able to easily identify the solution to math problems and stay focused on his work.
John Nash suffers from schizophrenia, a brain disease where they symptoms transform the mind. Though one of the symptoms plays to his benefit periodically, it ultimately leaves him in turmoil. One of John's positive symptoms of schizophrenia is that he has delusions of those that are in his life. His delusions can be traced back to the appearance of his roommate and best friend Charles, in graduate school. John also has the delusion of Charles' young niece Marcee, who he adores and accepts as another important person in his life. After doing work at the Pentagon, John again has delusions of a coworker William Parcher; who gives John assignments to complete for the Department of Defense. While completing some of his assignments, John becomes very paranoid of Russians chasing him and he develops erratic behaviors, another symptom of schizophrenia.
Those who experience the positive symptoms of schizophrenia typically lose a grasp of reality and have the symptoms present at random. John also was a schizophrenic with positive symptoms, that lost a grasp of what was fictitious and entity. A positive symptom of schizophrenia are the presence of hallucinations, sensory experiences without sensory stimulation, where one will see or hear things
