Bipolar Disorder: Mania, Depression, Types, and Treatment Options

Bipolar disorder is a chronic mood disorder marked by recurrent episodes of mania/hypomania and depression. It affects ~2–3% of adults and requires lifelong management.

Diagnostic Types

  • Bipolar I: ≥1 manic episode (may have hypomanic/depressive episodes).
  • Bipolar II: ≥1 hypomanic + ≥1 major depressive episode; no full mania.
  • Cyclothymic disorder: ≥2 years of hypomanic/depressive symptoms not meeting full episode criteria.
  • Other specified/unspecified: Subthreshold presentations.

Manic/Hypomanic Episode

Mania (≥1 week): Elevated/expansive/irritable mood, inflated self-esteem, decreased sleep need, pressured speech, flight of ideas, distractibility, increased goal-directed activity, risky behavior (spending, sex, investments). Causes marked impairment/hospitalization.

Hypomania (≥4 days): Similar symptoms but not severe enough for marked impairment; no psychosis.

Major Depressive Episode (≥2 weeks)

  • Depressed mood/anhedonia
  • Weight/appetite change, sleep disturbance
  • Fatigue, worthlessness/guilt
  • Diminished concentration, suicidality

Treatment

Mood Stabilizers (Foundation)

  • Lithium: Gold standard; reduces mania, depression, suicide risk. Requires monitoring (levels, thyroid, renal).
  • Valproate: Effective for mania, rapid cycling.
  • Lamotrigine: Best for depression prophylaxis.
  • Carbamazepine: Alternative.

Atypical Antipsychotics

  • Quetiapine, lurasidone, cariprazine, aripiprazole—FDA-approved for acute mania and/or bipolar depression.

Antidepressants: Use with Caution

Only with a mood stabilizer (risk of manic switch). Not monotherapy.

Psychotherapy

  • CBT, IPSRT (interpersonal and social rhythm therapy), family-focused therapy, psychoeducation.

Lifestyle

  • Regular sleep-wake cycle (critical)
  • Avoid alcohol/substances
  • Stress management

Long-Term Goals

Remission, relapse prevention, functional recovery. Collaborative care with psychiatry, therapy, and primary care optimizes outcomes.

Bipolar disorder is treatable. With proper management, people live full, productive lives.
