Second-generation antipsychotics treat which symptoms of schizophrenia?

• A. Positive symptoms only
• B. Negative symptoms only
• C. Both positive and negative symptoms
• D. Neither positive nor negative symptoms

Answer: (D)

Second-generation antipsychotics address both positive and negative symptoms because of their broader receptor actions. They block dopamine D2 receptors in the mesolimbic pathway, which helps reduce positive symptoms like delusions and hallucinations. At the same time, they block serotonin 5-HT2A receptors, which can increase dopamine activity in the prefrontal cortex and support improvements in some negative symptoms such as lack of motivation and social withdrawal. This dual action gives these medications the ability to impact a wider range of schizophrenia symptoms than older antipsychotics, and they typically cause fewer motor side effects, making them a common first choice. Still, responses vary, and managing negative symptoms often benefits from additional psychosocial interventions alongside medication.
