Which condition is listed as a differential diagnosis for Schizophreniform Disorder?

• A. Autism Spectrum Disorder
• B. Post-Traumatic Stress Disorder
• C. Obsessive-Compulsive Disorder
• D. Attention-Deficit/Hyperactivity Disorder

Answer: (B)

The main idea here is how to tell apart psychotic-spectrum presentations from trauma-related ones. Schizophreniform disorder centers on core psychotic symptoms—delusions, hallucinations, and disorganized thinking or behavior—that last between 1 and 6 months. Post-traumatic stress disorder is listed as a differential diagnosis because trauma exposure can produce symptoms—intrusive memories, hypervigilance, avoidance, and mood changes—that can resemble psychotic experiences, especially early on or in severe cases. The key to distinguishing them is the overall pattern and context: schizopherniform features are dominated by fixed psychotic symptoms not tied to trauma, whereas PTSD revolves around trauma-related re-experiencing and avoidance with a different cluster of symptoms and a clear link to a traumatic event. The other disorders—Autism Spectrum Disorder, Obsessive-Compulsive Disorder, and Attention-Deficit/Hyperactivity Disorder—do not typically present with the primary psychotic symptom profile or the trauma-linked symptom clusters that would lead clinicians to consider PTSD as the differential.
