Bipolar disorder

Bipolar disorder is a mental-health condition marked by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). These shifts differ from ordinary ups and downs; they can impair judgment, energy, sleep, behavior, and the ability to think clearly, and they interfere with work, school, and relationships.

There are several types, including bipolar I (with full manic episodes), bipolar II (hypomania plus major depression), and cyclothymic disorder. Bipolar disorder is lifelong but highly treatable. Mood stabilizers, atypical antipsychotics, psychotherapy, and regular routines help most people achieve substantial stability and a good quality of life.

Manic episode (bipolar I) may include:

• Elevated, expansive, or irritable mood lasting at least a week (or any duration if hospitalization is needed)
• Inflated self-esteem or grandiosity
• Decreased need for sleep
• Increased talkativeness or pressured speech
• Racing thoughts or flight of ideas
• Distractibility
• Increased goal-directed activity or agitation
• Risky behavior (spending sprees, sexual indiscretions, foolish investments)

Hypomania is similar but less severe and does not cause marked impairment or psychosis.

Depressive episode includes persistent low mood, loss of interest, changes in sleep and appetite, fatigue, worthlessness or guilt, concentration problems, and sometimes suicidal thoughts.

Mixed features (symptoms of mania and depression at the same time) are common and can be especially distressing.

Bipolar disorder appears to result from a combination of:

• Genetic vulnerability (strong familial pattern; many genes involved)
• Differences in brain structure and neurotransmitter systems
• Stress, sleep disruption, substance use, and major life events that can trigger episodes in susceptible people

It is a biological brain disorder, not a character flaw or simple reaction to life circumstances.

Risk factors include:

• Family history of bipolar disorder or depression
• Periods of high stress or traumatic events
• Substance use (can trigger or worsen episodes)
• Sleep disruption
• Onset is typically in late adolescence or early adulthood, though it can appear later

Without effective treatment, bipolar disorder can lead to:

• Substance use disorders
• Suicide and self-harm (risk is significantly elevated)
• Legal and financial problems from manic behavior
• Damaged relationships and job loss
• Poor physical health and coexisting anxiety or ADHD
• Hospitalizations

Consistent treatment greatly reduces these risks.

Bipolar disorder cannot be prevented, but episodes can often be prevented or minimized by:

• Taking prescribed medicines consistently even when feeling well
• Maintaining regular sleep and daily routines
• Avoiding alcohol and recreational drugs
• Learning early warning signs of mania and depression and having an action plan
• Ongoing psychotherapy and follow-up care
• Stress management and social support

Diagnosis is clinical and based on a detailed history of mood episodes from the patient and, when possible, family or close contacts. Structured interviews and mood questionnaires help. Medical evaluation rules out thyroid disease, substance effects, and other contributors. Bipolar disorder is sometimes initially misdiagnosed as unipolar depression; asking specifically about past manic or hypomanic symptoms is essential before starting antidepressants alone.

Seek professional help for mood swings that affect relationships, work, or safety; for depressive episodes with suicidal thinking; or when others express concern about your behavior during high-energy periods. Emergency care is needed for suicidal plans or intent, psychosis, or behavior that endangers self or others.

If you or someone you know is in crisis, contact emergency services or a crisis line immediately.

Treatment is long-term and multimodal:

Medicines

• Mood stabilizers (lithium, valproate, lamotrigine, carbamazepine)
• Atypical antipsychotics (quetiapine, aripiprazole, olanzapine, lurasidone, cariprazine, and others) for mania, depression, or maintenance
• Careful use of antidepressants only with a mood stabilizer, because antidepressants alone can trigger mania in some people
• Regular monitoring for side effects and blood levels when indicated (lithium, valproate)

Psychotherapy

• Psychoeducation
• Cognitive behavioral therapy
• Interpersonal and social rhythm therapy (emphasizes routine and sleep)
• Family-focused therapy

Other — electroconvulsive therapy for severe or treatment-resistant episodes; treatment of substance use and medical comorbidities; crisis planning.

Daily strategies that support stability:

• Take medicines as prescribed; do not stop suddenly
• Keep a regular sleep–wake schedule
• Avoid alcohol and recreational drugs
• Track mood, sleep, and triggers in a simple log
• Build a support network and share a relapse-prevention plan with trusted people
• Exercise and maintain structured daily routines
• Seek help early when warning signs appear

Bring:

• A timeline of high and low mood periods, sleep changes, and related behaviors
• Family history of mood disorders or suicide
• Complete medication and substance-use history
• Notes from someone who has observed you during different mood states, if available
• Questions about diagnosis, medicine options, side effects, and therapy
