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.
What to do
- Track episodes, not days. Note stretches of high energy with little sleep, and the low stretches.
- Tell the clinician about the highs. That detail changes the diagnosis and the medication choice.
- Take the consequences seriously. Impulsive spending, risky sex, quitting jobs during a high: classic signals.
- Treat it early. Mood stabilizers plus therapy work well. In crisis: 988 in the US, or your local crisis line.
