Final answer:
Chronic schizophrenia is the term for schizophrenia that develops gradually over time, requiring ongoing treatment with antipsychotic medications.
Step-by-step explanation:
Schizophrenia that develops gradually over a long period of time is called chronic schizophrenia. Unlike reactive or acute schizophrenia, which typically begins suddenly and may improve with treatment over time, chronic schizophrenia involves a gradual decline in functioning and is characterized by long-term symptoms. Treatment typically involves antipsychotic medications and possibly other therapies, but it is important to note that while these treatments can manage symptoms, they do not cure the underlying condition.
