Does the absence of hallucinations or auditory hallucinations mean it's not schizophrenia?

　　"Jingfen" refers to schizophrenia. It is possible to have schizophrenia without hallucinations or auditory hallucinations, but conditions such as depression and anxiety disorders cannot be ruled out either. The specific analysis is as follows:

　　1. Yes

　　Schizophrenia is a severe mental illness whose typical symptoms include hallucinations, auditory hallucinations, delusions, emotional blunting, disorganized thinking, and so on. The diagnosis of schizophrenia must meet specific diagnostic criteria, including the presence of at least one symptom such as hallucinations, auditory hallucinations, or delusions, with symptoms persisting for at least one month. Therefore, even in the absence of typical symptoms like hallucinations or auditory hallucinations, if other symptoms—such as emotional blunting, disorganized thinking, or social withdrawal—are present, a diagnosis of schizophrenia may still be considered.

　　2. No

　　Other mental disorders may also present similar symptoms, such as depression, anxiety disorders, or obsessive-compulsive disorder. Therefore, a comprehensive psychiatric evaluation and diagnosis are necessary to determine the exact cause and type of disorder.

　　If any symptoms of mental illness occur, it is recommended to seek medical help promptly and receive professional diagnosis and treatment to alleviate symptoms and improve quality of life.
