Bipolar disorder causes shifts in which of the following?

Bipolar disorder is a mental health condition characterized by significant changes in a person's mood, energy levels, and activity levels. These shifts can range from manic episodes, where the individual may feel extremely elevated or euphoric, with high energy and increased activity, to depressive episodes, where they may feel hopeless, fatigued, and withdrawn.

This disorder can lead to emotional states that vary widely, impacting not just mood but also how much energy the individual feels and how active they are in their daily lives. Thus, the correct answer encompasses all these aspects: mood, energy, and activity levels, reflecting the complex nature of bipolar disorder and how it affects individuals. Understanding this multifaceted impact is crucial for effective treatment and support.
