Which neurotransmitter is commonly associated with depression and anxiety in pharmacology discussions?

• A. Dopamine
• B. Serotonin
• C. Norepinephrine
• D. GABA

Answer: (B)

Serotonin is central to mood regulation, influencing feelings of well-being, sleep, appetite, and emotional balance. In pharmacology, disruptions in serotonergic signaling are repeatedly linked to depressive and anxious symptoms, which is why this neurotransmitter sits at the heart of many antidepressant strategies. The most common first-line meds are SSRIs, which block the serotonin transporter to increase serotonin levels in the synapse, helping improve mood and reduce anxiety. Other neurotransmitters like dopamine, norepinephrine, and GABA contribute to related aspects of mood and anxiety, but the classic focus in treating depression and anxiety centers on serotonin due to the effectiveness of serotonergic antidepressants and the broad role serotonin plays in mood regulation.
