Which is MOST likely to elevate the mood in a person with depression?

Question

Quizplus · Accepted Answer

An increase in the levels of norepinephrine is most likely to elevate the mood in a person with depression. This is because norepinephrine is a neurotransmitter that plays a role in regulating mood and is often low in people with depression. Medications that increase the levels of norepinephrine, such as SNRIs (serotonin-norepinephrine reuptake inhibitors), are commonly used to treat depression.

Therefore, inhibition of serotonin synthesis (A) and blocking synaptic transmission at norepinephrine synapses (D) are both unlikely to elevate mood, as they would decrease levels of important neurotransmitters. A decrease in the levels of serotonin (B) may not necessarily elevate mood, as serotonin plays a complex role in regulating mood and has different effects in different individuals.
