Answer to Question 1

Ans: A, B, D
Psychoneuroimmunolo gy addresses possible explanations for the development of psychiatric disorders based on the interaction of the neurologic, endocrine, and immune systems. Areas addressed include immune dysregulation caused by neurotoxins affecting the brain tissue at locations such as receptor sites; disruption of the hypothalamicpituita rythyroid axis feedback system; and immune system dysfunction resulting from damage to the hypothalamus, hippocampus, or pituitary gland. Another area being studied is the role of natural killer cell function, which shows that natural killer cell activity varies in response to many emotional, cognitive, and physiologic stressors.

Answer to Question 2

Ans: C
Risk factor analysis is evaluated when determining genetic susceptibility, that is, predicting who is more likely to experience psychiatric disorders or certain conditions. Population genetics evaluates family studies that analyze the occurrence of a disorder among first-degree relatives, twin studies that analyze the presence (or absence) of a disorder in pairs of twins using concordance rates, and adoption studies that compare the risk of a disorder developing in offspring raised in different environments.
