Which symptom is commonly NOT associated with bipolar disorder?

Chronic low energy is commonly not associated with bipolar disorder, particularly when considering the cyclical nature of the disorder itself. Bipolar disorder is characterized by distinct mood episodes, including manic, hypomanic, and depressive states. During manic or hypomanic phases, individuals often exhibit increased energy, heightened activity levels, and reduced need for sleep. Conversely, during depressive episodes, individuals may experience low energy, but this is not a hallmark symptom of bipolar disorder on its own, as it can be a general symptom in many other mental health disorders.

In contrast, rapid mood changes are a defining feature of bipolar disorder, as individuals can quickly shift from elevated, euphoric moods to more depressive states. Lack of concentration is also associated with both manic and depressive phases, where individuals may struggle to focus due to racing thoughts or overwhelming feelings. Increased appetite may occur during depressive episodes, but it is not consistently noted in manic phases. Thus, chronic low energy does not align with the primary characteristics of bipolar disorder, making it the symptom least commonly associated with this condition.
