Bipolar disorder is characterized by significant mood swings that encompass both depressive episodes and manic or hypomanic episodes. Individuals with this disorder may experience profound lows, which can mimic depression, followed by extreme highs, where they may feel unusually energetic, euphoric, or irritable.

The other disorders mentioned do not specifically feature these distinct and alternating mood states.
