What are common signs of a manic episode in bipolar disorder?

A manic episode in bipolar disorder is characterized by a specific set of symptoms that reflect an elevation in mood and energy levels. The correct choice highlights several key features of a manic episode, including elevated mood and increased energy, which are essential indicators that this state has been reached. The decreased need for sleep is significant as individuals experiencing mania often feel rested despite not sleeping much, which can lead to further episodes of heightened activity. Impulsiveness is also a hallmark symptom, as individuals may engage in risky behaviors or make hasty decisions during a manic phase.

The other options include symptoms that are not typically associated with mania. While elevated mood and irritability might appear in some contexts, the overall combination in the first choice does not capture the energetic and impulsive nature typical of mania. The third option describes symptoms consistent with depression rather than a manic state. Similarly, the fourth option points to anxiety and compulsivity, which are also more aligned with anxiety disorders and obsessive-compulsive disorder, rather than manic episodes in bipolar disorder.
