A mental health client's symptomatology has been partially attributed to the effects of neuroplasticity. What statements best describes this phenomenon?
 
  A) Neuroplasticity is the ability of nervous tissue to change structure and functioning in response to new experiences.
  B) Neuroplasticity determines a client's response to psychotropic medications.
  C) Neuroplasticity initiates the neuroendocrine-mediated physiologic events that prepare the body for fight or flight.
  D) Neuroplasticity is the process by which the information in RNA produces strings of amino acids.

Question 2

Rather than being 100, concordance rates for schizophrenia in monozygotic twins are only 50. Which of the following statements best explains this phenomenon?
 
  A) Genetic predisposition to disease is frequently overstated.
  B) One twin is inherently more vulnerable in every case.
  C) Environmental experiences affect gene expression.
  D) The genetic pathway responsible for vulnerability is unrelated to being a twin.

Answer to Question 1

Ans: A
Feedback:
The brain's ability to develop and alter in response to experience is known as neuroplasticity. This means that the brain adapts to new conditions during its maturation and during its constant interaction with its environment. In a sense, this also means that, to some degree, humans can create their own brains by exposing them to certain experiences. Neuroplasticity is not a component of gene expression and it does not initiate the fight-or-flight response.

Answer to Question 2

Ans: C
Feedback:
While human genes play an enormous role in certain pathologies, the pathophysiology of psychiatric disorders, like all disorders, depends on a complex interaction of genetic factors and environmental factors. These genetic and environmental factors also affect the brain's development and subsequent function. Identical genetic material does not necessarily guarantee the development of a disease. Inherent vulnerability does not adequately explain this phenomenon.
