Which of the following is a potential symptom of schizophrenia?

Delusions are a potential symptom of schizophrenia, which is characterized by false beliefs that are firmly held despite evidence to the contrary. Individuals with schizophrenia may experience a range of delusions, such as believing they are being persecuted, have extraordinary abilities, or are under some form of external control. These delusions can significantly impact their perception of reality and interfere with their ability to function in society.

In contrast, excessive energy, confidence, and clear thoughts are not associated with schizophrenia. While individuals may exhibit energy when experiencing mania or heightened moods, schizophrenia often involves disorganized thinking and cognitive impairments, rather than clarity and focus. Therefore, identifying delusions as a symptom is crucial for understanding and diagnosing schizophrenia effectively.
