Question

Quizplus · Accepted Answer

The dopamine model of schizophrenia proposes that excess dopamine activity in certain brain areas is responsible for its symptoms. Neuroleptics, which are antipsychotic medications that block dopamine receptors, have been found to effectively alleviate these symptoms, supporting the role of dopamine in the disorder. The other drugs listed (barbiturates, tricyclics, and hallucinogenics) are not typically used in the treatment of schizophrenia, and do not provide evidence for the dopamine model.
