• A. True
• B. False
• C. Sometimes true
• D. Not true

Answer: (A)

The key idea here is how schizophrenia is diagnosed based on symptom patterns, not just how prominent those symptoms are. To meet the diagnostic criteria, a person must show at least two of five symptom domains (delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, and negative symptoms) for a significant portion of time, with at least one of those two symptoms coming from the first three domains (delusions, hallucinations, or disorganized speech). There’s also a duration requirement over several months. The important nuance is that the delusions or hallucinations don’t have to be “prominent” or exceptionally severe for the diagnosis to be made. One can have two or more symptoms, such as disorganized speech plus negative symptoms, with only mild delusions or hallucinations, and still meet the criteria as long as the specified domains are present and duration criteria are met. This is why the statement that schizophrenia is diagnosed only when there are prominent delusions or hallucinations in addition to other required symptoms is not accurate in clinical practice—the emphasis is on the number and type of symptoms and their duration, not on how prominent they are.
