What role do pharmacological treatments play in psychology, and give two examples?

• A. Drugs modulate neurotransmitter systems to alleviate symptoms; e.g., SSRIs for depression and antipsychotics for schizophrenia
• B. Drugs cure mental illness instantly
• C. Drugs have no impact on neurotransmitters
• D. Drugs only affect peripheral systems, not brain

Answer: (A)

Pharmacological treatments in psychology work by altering neurotransmitter activity in the brain to reduce symptoms and improve functioning. For example, selective serotonin reuptake inhibitors increase the level of serotonin in the synapse, helping regulate mood in depression. Antipsychotics block dopamine receptors, diminishing dopamine signaling and helping reduce psychotic symptoms in schizophrenia. These drugs illustrate how changing brain chemistry can influence thoughts, mood, and behavior. They don’t cure mental illness instantly and are usually part of a broader treatment plan, with varying onset times and potential side effects.
