Bipolar disorder.
Recognizing the pattern.

Look for a change from your usual self.

Bipolar mood episodes involve changes in mood together with energy, activity, sleep, and behavior. They usually unfold over days or weeks. Having a difficult afternoon, feeling better after good news, or changing your mind frequently does not by itself establish bipolar disorder.

During depression, someone may lose interest in things they usually enjoy, feel hopeless, struggle to concentrate, or find everyday tasks exhausting. During mania or hypomania, energy and activity rise noticeably. Mood may feel unusually upbeat, intensely irritable, or both.

• Needing much less sleep while still feeling energized.
• Talking faster, having racing thoughts, or starting many projects.
• Feeling unusually powerful, confident, or capable.
• Spending, driving, or making other decisions in ways that are unusually risky.

What bipolar I and bipolar II mean.

Bipolar I involves at least one manic episode: a substantial change that severely disrupts life, may require hospitalization, or can include psychosis. Mania generally lasts at least a week, or any duration if hospitalization is necessary. Depression is common, but it is not required for the diagnosis.

Bipolar II involves hypomania and major depression, without a history of mania. Hypomania lasts at least four consecutive days and represents a clear change in functioning, but does not cause the severe impairment, hospitalization, or psychosis associated with mania. Bipolar II can still be profoundly disruptive, particularly because of depression.

Symptoms can also overlap. Someone may feel depressed while unusually energized, agitated, or mentally sped up. Tell your provider about that combination rather than waiting for it to fit a simple “high” or “low.”

Your history helps make sense of the present.

An evaluation considers the timing and length of episodes, changes in functioning, family history, medications, substance use, and possible medical explanations. With your permission, someone who knows you well may help describe changes you did not notice yourself.

Bring examples: a stretch of unusually little sleep, a sudden spending pattern, or a period when others said you seemed different. You do not need to arrive knowing the diagnosis.

Treatment aims for stability you can live with.

Medication choices depend on whether you are treating mania, depression, or preventing another episode. Mood stabilizers and certain antipsychotic medications have different roles; a medication that helps mania may not treat bipolar depression equally well. Antidepressants alone are generally avoided, particularly in bipolar I, because they can trigger mania or destabilize mood.

Therapy, consistent sleep, and a plan for early warning signs also matter. Agree on whom to contact if sleep drops or behavior changes, and include trusted people if you want their support.

Seek urgent assessment for escalating energy with very little sleep, dangerous behavior, or losing touch with reality. If you feel unsafe or are in immediate danger, call 911. Effective care can help you maintain relationships, work toward your goals, and spend more of your life feeling like yourself.
