The film “A Beautiful Mind” is based on the case study of real-life mathematician John Nash, who suffered from schizophrenia. Aspects of schizophrenia affected John Nash in several ways. Ethics is defined in the manual as follows: “Are the tools or behaviors one employs to achieve a desired outcome. The means can be good or bad. Ends are the outcomes one wishes to achieve” (Polgar and Thomas, 2008). The film's case study includes the signs and symptoms, social effects and treatment of schizophrenia and the consequences it had on his overall career. John Nash's behaviors fell into the category of ethical, unethical, Machiavellian and subjectively this was due to the fact that he suffered from schizophrenia.SchizophreniaSchizophrenia is a mental illness that has major consequences for those infected, their family and society. Affected individuals may experience a wide range of disturbances in their ability to see, hear and process information from the world around them. They also experience disruptions in their normal thought processes, as well as their emotions and behaviors. Symptoms: • Positive symptoms: Schizophrenia denotes the production of abnormal phenomena. These include hallucinations and delusions. • Negative symptoms: denote a lack of emotions and feelings, blunted affect, and a loss of normal behaviors. These include emotional blunting or flattening (inability to express emotions), alogia (poverty or disruption of speech), avoilition (lack of willingness to interact with the world), anhedonia (the inability to experience pleasure), asociality (the preference for isolation). , and catatonia, which are a group of four cognitive and motor symptoms (Tsuang et al., 2011). Individuals who suffer from schizophrenia experience negative social effects middle of paper...... When it came to ethics, Nash's results were a little bit of everything.
