Which of the following does NOT indicate a symptom of Schizophrenia?

Severe mood swings are not classified as a symptom of Schizophrenia. In contrast, the symptoms of Schizophrenia prominently include delusions, hallucinations, and disorganized speech. Delusions are fixed false beliefs that are resistant to reasoning or confrontation with actual facts. Hallucinations involve sensory perceptions without external stimuli, most commonly auditory hallucinations. Disorganized speech reflects the disorganization of thoughts, which can manifest as incoherent or nonsensical speech patterns.

While Schizophrenia can include mood disturbances as part of the disorder, severe mood swings are more characteristic of mood disorders, such as Bipolar Disorder. Hence, focusing on the definitive symptoms outlined in the DSM-5 for Schizophrenia helps clarify why severe mood swings do not fall under its symptomatology.
