Final answer:
A doctor would not find case studies and interviews in the Diagnostic and Statistical Manual of Mental Disorders (DSM). The answer to the student's multiple-choice question is (b) case studies and interviews, which a doctor would not find in the DSM.
Step-by-step explanation:
The Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, provides a comprehensive classification of mental disorders. It is a critical tool used by healthcare professionals to diagnose and treat individuals. When referring to the DSM, a doctor would find major symptoms and associated behaviors of mental disorders, as well as an average age at which the disorders typically appear.
However, the DSM does not include case studies and interviews; these are typically found in academic and research publications that discuss the practical findings from individual cases or studies. Furthermore, while the DSM may provide descriptive information on disorders, it does not focus on explaining the causes of disorders due to the complexity and variety of contributing factors, such as genetics, environment, and individual experiences.
Understanding why it is difficult to identify the causes of many nervous system disorders relates to the nature of these disorders. There are often no obvious defects in brain structure, the associated genes may be unknown, and the onset and display of symptoms can vary greatly between patients. This is why treatment options are often focused on symptom management rather than addressing the root causes. instead, they would find major symptoms, associated behaviors, and average age of onset for mental disorders, but not detailed explanations of the causes.
