Final answer:
Cognitive-behavioral therapy is not the primary treatment for schizophrenia; that role is filled by antipsychotic medications. However, CBT can be a supportive adjunct therapy alongside medication for managing symptoms and improving life quality.
Step-by-step explanation:
The statement that cognitive-behavioral therapy (CBT) is the mainline treatment for schizophrenia is false. While CBT is a valuable psychotherapeutic approach that addresses cognitive processes and behaviors, the primary treatment for schizophrenia involves antipsychotic medications. These medications are key to managing the symptoms of schizophrenia, which can include hallucinations, delusions, and cognitive impairments. They work primarily by blocking dopamine receptors to reduce dopamine neurotransmission. Nonetheless, CBT can be an important adjunctive treatment for helping individuals manage the residual symptoms of the disorder and improve the quality of life.
