Final answer:
According to early psychodynamic approaches, schizophrenia symptoms are believed to result from excessive dopamine activity.
Step-by-step explanation:
According to early psychodynamic approaches, schizophrenia symptoms are believed to result from excessive dopamine activity. Dopamine is a neurotransmitter that plays a role in various functions in the brain, including movement, motivation, and reward. An overactive dopamine system has been associated with the positive symptoms of schizophrenia, such as hallucinations and delusions. Antipsychotic medications used to treat schizophrenia work by blocking dopamine receptors in order to reduce dopamine activity and alleviate symptoms.
