What are the signs of bipolar disorder?

Last updated September 3, 2026.

Episodes, not moodiness: distinct stretches of unusually high, energized, or irritable behavior - little sleep, racing thoughts, impulsive spending or risk - alternating with depressive stretches, per NIMH. Mania lasts at least a week or forces hospitalization; hypomania is the lower-volume version. The diagnostic trap: people seek help in the low stretches, so bipolar masquerades as plain depression for years - always mention the high periods to your clinician, because antidepressants alone can worsen the cycling.
