Bipolar Disorder

Bipolar disorder, formerly called manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. These mood episodes are distinctly different from the typical ups and downs that everyone experiences. The symptoms of bipolar disorder can result in damaged relationships, poor job or school performance, and even suicide.

The condition typically involves periods of abnormally elevated mood and energy (mania or hypomania) alternating with periods of depression. During manic phases, individuals may feel euphoric, full of energy, or unusually irritable. During depressive phases, they may feel sad, hopeless, and lose interest in most activities. The frequency and duration of these episodes vary widely among individuals.

Bipolar disorder is a lifelong condition, but mood swings and other symptoms can be managed with a treatment plan. Most people with bipolar disorder can lead full and productive lives when they receive appropriate treatment. The key is recognizing the signs and symptoms and seeking help early.

Bipolar I Disorder

• Defined by manic episodes lasting at least 7 days
• Manic symptoms severe enough to need immediate hospital care
• Usually also have depressive episodes lasting at least 2 weeks
• Mixed episodes (depression and mania together) possible
• Most severe form of bipolar disorder

Bipolar II Disorder

• Pattern of depressive and hypomanic episodes
• No full-blown manic episodes
• Hypomania is less severe than mania
• Depression often more prominent and longer-lasting
• Can be just as impairing as Bipolar I

Cyclothymic Disorder (Cyclothymia)

• Periods of hypomanic and depressive symptoms
• Symptoms last for at least 2 years (1 year in children/teens)
• Symptoms don't meet full criteria for episodes
• Never without symptoms for more than 2 months
• May develop into Bipolar I or II

Other Specified and Unspecified Bipolar Disorders

• Bipolar symptoms that don't match the above categories
• May be caused by drugs, alcohol, or medical conditions
• Includes rapid cycling (4+ episodes per year)

Mixed Features

Some people experience episodes with mixed features, having symptoms of both mania/hypomania and depression simultaneously. This might include feeling very sad while also feeling extremely energized.

Psychotic Symptoms

Severe episodes may include psychotic symptoms:

• Hallucinations: Seeing or hearing things that aren't there
• Delusions: False beliefs not based in reality
• Paranoia: Unreasonable suspicions
• These symptoms tend to match the mood (mood-congruent)

Between Episodes

Many people with bipolar disorder experience periods of normal mood between episodes. However, some may have residual symptoms or rapid cycling between mood states.

Biological Factors

Genetics

• Strong genetic component - runs in families
• If one parent has bipolar: 10-25% chance in children
• If both parents: 10-50% chance
• Identical twin: 40-70% chance
• Multiple genes involved, not single "bipolar gene"

Brain Structure and Function

• Differences in brain structure and activity
• Abnormalities in neurotransmitter systems
• Changes in dopamine, serotonin, norepinephrine
• Circadian rhythm disturbances
• Hormonal imbalances may play role

Environmental Triggers

• Stressful life events: Death, divorce, job loss
• Substance abuse: Can trigger or worsen episodes
• Sleep disruption: Major trigger for mood episodes
• Seasonal changes: Some have seasonal patterns
• Medications: Antidepressants, steroids can trigger mania
• Childbirth: Postpartum period high risk

Risk Factors

• Family history of bipolar or other mood disorders
• First-degree relative with bipolar disorder
• Periods of high stress
• Drug or alcohol abuse
• Major life changes or trauma
• Other mental health conditions (anxiety, ADHD)

Diagnosing bipolar disorder can be challenging and often takes time. Many people with bipolar disorder are initially misdiagnosed with depression, as depressive episodes often occur first or are more recognized.

Diagnostic Process

• Psychiatric evaluation: Detailed discussion of symptoms
• Medical history: Including family history
• Mood charting: Track mood patterns over time
• Physical exam: Rule out other conditions
• Lab tests: Check thyroid, drug screening
• DSM-5 criteria: Must meet specific criteria

Diagnostic Criteria

For Manic Episode

• Distinct period of elevated, expansive, or irritable mood
• Lasting at least 1 week (or any duration if hospitalized)
• 3+ symptoms (4 if mood is only irritable)
• Significant impairment or need for hospitalization

For Hypomanic Episode

• Same symptoms as mania but less severe
• Lasting at least 4 consecutive days
• Observable by others but not severe impairment
• No psychotic features

For Major Depressive Episode

• 5+ symptoms during same 2-week period
• Must include depressed mood or loss of interest
• Significant distress or impairment

Differential Diagnosis

Conditions that may mimic bipolar disorder:

• Major depressive disorder
• Borderline personality disorder
• ADHD
• Schizophrenia or schizoaffective disorder
• Substance use disorders
• Thyroid disorders
• Brain tumors or neurological conditions

Bipolar disorder requires lifelong treatment, even during periods when you feel better. Treatment is usually guided by a psychiatrist experienced in treating bipolar disorder, often with a team approach.

Medications

Mood Stabilizers

• Lithium: Gold standard, prevents mania and depression
• Valproate (Depakote): Effective for mania
• Carbamazepine (Tegretol): Alternative mood stabilizer
• Lamotrigine (Lamictal): Better for bipolar depression
• Regular blood tests required for monitoring

Antipsychotics

• Second-generation: Olanzapine, quetiapine, risperidone
• Newer options: Aripiprazole, lurasidone
• Used for mania, mixed episodes, maintenance
• Some approved as monotherapy
• Watch for metabolic side effects

Antidepressants

• Used cautiously - can trigger mania
• Usually combined with mood stabilizer
• SSRIs or bupropion preferred
• Avoid in Bipolar I without mood stabilizer

Other Medications

• Benzodiazepines: Short-term for anxiety/sleep
• Sleep aids: For insomnia
• Thyroid hormone: Sometimes augments treatment
