Introduction
Bipolar disorder is primarily characterized by alternating mood fluctuations between mania/hypomania and depression, with the core issue centered on abnormal emotional regulation. In most cases, patients have normal cognitive function during non-episodic periods; however, during severe episodes (such as severe mania or depression), psychotic symptoms such as hallucinations and delusions may emerge, requiring treatment with antipsychotic medications in addition to standard therapy.

Generally, bipolar disorder falls within the category of mental disorders. Some episodes may be accompanied by psychotic symptoms, but it is not equivalent to the traditional understanding of psychosis primarily characterized by hallucinations and delusions. If there are concerns, early medical consultation is recommended. The detailed explanation is as follows:

Bipolar disorder is mainly characterized by mood fluctuations between mania/hypomania and depression, with the core issue being abnormal emotional regulation. In most cases, patients have normal cognitive function during non-episodic periods. Psychotic symptoms such as hallucinations or delusions may only occur during severe episodes (e.g., severe mania or depression), at which time antipsychotic medications may be required in addition to standard treatment.

Bipolar disorder differs from conditions whose core feature is persistent psychotic symptoms (such as schizophrenia). In the former, mood symptoms are more prominent, and psychotic symptoms are typically secondary and vary with mood changes; in the latter, psychotic symptoms persist over time, while mood disturbances are relatively less pronounced. The two disorders also differ in treatment approaches and prognosis.

If significant mood swings occur along with abnormal thought patterns or perceptual experiences, timely evaluation by a psychiatrist is essential. A professional assessment can ensure an accurate diagnosis, preventing delays in appropriate treatment due to misunderstandings about disease classification, thereby supporting better recovery outcomes.
