Schizophrenia vs schizophreniform: which criterion primarily distinguishes them?

• A. Prominent hallucinations, disorganized speech, and negative symptoms
• B. Delusions
• C. Mood disturbances
• D. Cognitive decline

Answer: (A)

Duration of symptoms is the key factor that separates these two disorders. Both share the same psychotic features—delusions, hallucinations, disorganized speech, disorganized or catatonic behavior, and negative symptoms—so the content isn’t what differentiates them. Schizophreniform disorder is diagnosed when these symptoms have been present for at least one month but less than six months. If the disturbance lasts six months or longer, the diagnosis is schizophrenia (assuming criteria such as at least one month of active-phase symptoms are met). Mood symptoms can occur with either condition but don’t define the distinction, and cognitive decline isn’t the primary criterion used to differentiate them.
