John Nash in A Beautiful Mind, and a DSM-4 reading

Before psychiatric illness was treated as a field of its own, schizophrenia was often shunned as a curse, or as something that brought misfortune if you came near it. The film A Beautiful Mind is taken up here to look at the psychological trouble and the unusual behavior of its central figure, and then to set that against DSM-4, and against the treatments and the precautions that are named. Schizophrenia is given as occurring in about 1 percent of the world’s population. A complete cure is said not to have been found, and it has therefore been known as an incurable illness. It is also argued, without a calendar year attached, that if medicine and psychotherapy are kept up, the illness can be eased to some degree. It is not treated here as something a person only has from birth; it can also arise later, and so it is not something simply to be avoided.

John Nash enters Princeton on a full Carnegie scholarship, a mathematical prodigy, inward and blunt. The only friend who seems to be there is a roommate, who later turns out to have been a hallucination he did not see through for a long time. He comes to think of himself as a secret agent for an intelligence bureau — read as a grandiose delusion — talks to empty air, takes newspapers and magazines for codebreaking and fills the room with them, writes formulas on the windows, and can be impulsive and violent. As the unusual behavior grows he is forced into a psychiatric hospital, does not accept the illness, and takes the admission as a confinement meant to hide information about him. After discharge the medicine seems to ease the symptoms for a time, but he stops it in secret because he cannot concentrate on his research; the symptoms return, and he sees Parcher and Charles again. His wife does not simply send him away; she stays with him, and he later works again as a professor and receives the Nobel Prize in economics. Under DSM-4, two or more of the listed symptoms over a month are looked for: delusions, hallucinations, disorganized speech, generally tense or catatonic behavior, negative symptoms, affective flattening, and mutism. In the film the trouble is read as beginning when he enters the university: an isolated life, a world of his own, and the pressure of having to follow the school’s system. The account stays with DSM-4; a later edition is not brought in.

Medicine, admission, and what is not claimed as a cure

When schizophrenia is present, hallucinations and voices in the head can make it hard to tell what is real, and mutism can appear as well. The symptoms can be more severe than in some other psychiatric illnesses, and living together in a family can become difficult. In the film the degree of Nash’s illness is read as very serious, not least because the roommate and everyone tied to the codebreaking work were not real.

The most important treatment named is medicine, and it is also named as the method a person can take up by their own will without a great cost. Hospitalization, individual psychotherapy, group therapy, family therapy, and behavior therapy are listed as well. In the film the medicine seems to ease the symptoms for a time, and then he stops it because it stands in the way of his research. From that, the account takes the point that treatment should not be forced blindly, and that ongoing medicine should go with psychotherapy aimed at living in society. Admission is for a clear diagnosis in a specialized place, consistent medicine, and protection from harm to oneself or to others, and it can let a family keep a basic daily life. A long stay that has no point, though, can cut sociability and weaken family ties, so it is not to be prolonged without reason. Rarely a neurosurgical operation is used, and a residential group-treatment center is named for people who cannot easily live with their family. A complete cure is not claimed. The same Korean report, at fuller length, is on CampusDown.
