Final answer:
Individuals with reactive schizophrenia predominantly exhibit positive symptoms that are manageable with antipsychotic medications. These symptoms are a result of excessive dopamine activity, which the drugs aim to counteract.
Step-by-step explanation:
People with reactive schizophrenia more often have the positive symptoms that respond to drug therapy. Positive symptoms, including hallucinations, delusions, and disorganized thinking, are typically associated with overactive dopamine neurotransmission in the brain. Antipsychotic medications, which block dopamine receptors, are effective in treating these positive symptoms, though they do not cure the underlying condition of schizophrenia.
