John Nash is a brilliant mathematician who struggled with paranoid schizophrenia for several decades of his life. Nash exhibited erratic behavior and suffered from auditory hallucinations. He believed he was receiving messages from space and was convinced there was a conspiracy to undermine the American government. On one occasion, Nash broke into the offices of the New York Times and accused them of preventing him from receiving important encrypted messages that only he could decipher. Nash's wife admitted him to a mental hospital just two years after their marriage (Nasar, 2001). The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) is a multiaxial classification system for mental disorders. The first axis includes an extensive list of clinical syndromes that typically cause significant impairments. In the case of John Nash, his Axis I diagnosis would be paranoid schizophrenia. According to the text, “people with paranoid-type schizophrenia have an organized system of delusions and auditory hallucinations that can guide their lives” (Comer, 2011, p. 364). Nash suffered from delusions of persecution, fearing that people were out to get him. The second axis includes chronic conditions that are often overlooked in the presence of Axis I conditions. Nash's Axis II diagnosis would most likely be a paranoid personality disorder. People who suffer from this disorder often feel in danger and look for evidence of that danger, ignoring logic and facts. John Nash exhibited this type of behavior. He admitted that his behavior seemed irrational, even to him, but he was convinced that he was in danger and tried to expose any threat and make those around him aware of the danger he faced. The third axis includes r...... half of paper ......and, mouth, face or whole body; involuntary chewing, sucking, and lip smacking; and jerky movements of the arms, legs, or entire body” (Comer, 2011, p. 379). If he were prescribed a neuroleptic drug, Nash would most likely follow in the footsteps of other schizophrenia patients and decide that the side effects of the drugs make the symptoms of the disorder itself more unbearable. New drugs are being produced to address the problem of unwanted and intolerable side effects of conventional antipsychotic drugs. Works CitedComer, R. J. (2011). Fundamentals of abnormal psychology.
