Which class modifies psychotic behavior in conditions such as schizophrenia?

• A. Antidepressant
• B. Neuroleptic
• C. Anxiolytic
• D. Stimulant

Answer: (B)

Neuroleptics modify psychotic behavior by blocking dopamine D2 receptors in brain pathways that drive the positive symptoms of schizophrenia, such as hallucinations and delusions. This dopamine blockade in the mesolimbic system reduces these symptoms, making this drug class the primary option for treating the core psychotic features. Other types of drugs don’t target this dopamine-driven aspect: antidepressants work mainly on serotonin and/or norepinephrine to treat mood symptoms, anxiolytics address anxiety, and stimulants boost dopaminergic activity which can worsen psychosis rather than improve it. Some neuroleptics, especially the newer ones, also affect serotonin receptors, which can help with additional symptoms and side-effect profiles, but the key action that modifies the psychosis remains dopamine D2 antagonism.
