Which of the following is NOT a symptom of the manic phase of bipolar mood disorder?

The correct choice is based on the characteristics associated with the manic phase of bipolar mood disorder. Inflated self-esteem is indeed a symptom of mania; individuals may experience an exaggerated sense of self-confidence during this phase.

The other symptoms listed—euphoria, high levels of verbal output, and pressured speech—are classic manifestations of mania. Euphoria describes a state of intense excitement and happiness that can be disruptive. High levels of verbal output refer to an increase in talking, often rapidly and to the point where it is challenging for others to engage in conversation. Pressured speech is characterized by a compelling urge to speak that can resemble a stream-of-consciousness and may push others out of the dialogue.

To understand this topic in greater depth, recognizing that inflated self-esteem is a symptom of manic episodes helps clarify why it is not the correct choice when identifying what is NOT a symptom of this phase. Each symptom is critical for accurate diagnosis and understanding the manic phase's nature within bipolar disorder.
