Which symptom is NOT typical of bipolar disorder?

In bipolar disorder, symptoms form part of manic and depressive episodes that significantly impact a person's mood and behavior. Increased energy during manic phases is indeed a hallmark symptom, as individuals often feel extremely energized, elated, or unusually irritable during these times. Extreme mood changes are also characteristic of the disorder, with marked shifts from manic highs to depressive lows.

Persistent low mood aligns with the depressive episodes experienced in bipolar disorder, where individuals may feel overwhelming sadness or hopelessness for extended periods. However, hallucinations are not a common symptom of manic episodes in bipolar disorder. Instead, they may indicate a more severe form of the disorder or conditions such as schizophrenia. Hallucinations can occur in psychosis-related disorders, but in the typical presentation of bipolar disorder, they are not a defining feature. Thus, the symptom that does not fit with the typical profile of bipolar disorder is indeed related to hallucinations during manic episodes.
