A client with a history of epilepsy has recently experienced more frequent seizures, often followed immediately by episodes of aggressive behavior. Which biological abnormality is likely to be present in this client?
 
  1. A mutation on the genes that encode components of the serotonin system
  2. Serum toxicity resulting from chronic exposure to lead
  3. A deficit of gamma-aminobutyric acid
  4. A problem with the amygdala/temporal lobe

Question 2

A 13-year-old client was admitted for giving a younger sister a black eye and throwing a cat out the window. Which neurotransmitter imbalance is not likely to be associated with this behavior?
 
  1. Dopamine excess
  2. Serotonin deficit
  3. Gamma-aminobutyric acid (GABA) deficit
  4. Acetylcholine excess

Answer to Question 1

4
Rationale: Postictal aggressive behavior is associated with a problem with the amygdala/temporal lobe. A deficit of gamma-aminobutyric acid and a mutation on the genes that encode components of the serotonin system are biological factors associated with etiology of aggression but do not fit with the scenario. Lead toxicity is an environmental factor, not a biological factor.

Answer to Question 2

4
Rationale: Aggressive behavior is associated with deficits of acetylcholine, serotonin, GABA, and an excess of dopamine.
