Bipolar Disorder: Understanding Mood Episodes

Bipolar disorder is a chronic mental health condition characterized by extreme mood swings—from emotional highs (mania or hypomania) to lows (depression). With proper treatment and support, most people with bipolar disorder can lead fulfilling, productive lives.

What is 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 shifts are far more severe than the normal ups and downs everyone experiences.

People with bipolar disorder experience periods of unusually intense emotion, changes in sleep patterns and activity levels, and uncharacteristic behaviors—often without recognizing their likely harmful or undesirable effects. These distinct periods are called "mood episodes."

Mood episodes are drastically different from the moods and behaviors typical for the person. During an episode, symptoms last most of the day, nearly every day, for at least several days or weeks. Symptoms can also sometimes occur together in "mixed features" episodes.

💡 Key Distinction

Bipolar disorder is not the same as having mood swings. Everyone has ups and downs, but bipolar episodes are severe, prolonged, and significantly impair daily functioning or require hospitalization.

Types of Bipolar Disorder

There are three main types of bipolar disorder. All involve clear changes in mood, energy, and activity levels that differ from the person's usual behavior.

Type Manic Episodes Depressive Episodes Key Features
Bipolar I Full mania (≥7 days or hospitalization) Common but not required Most severe manic symptoms; may include psychosis
Bipolar II Hypomania only (≥4 days) Required (≥2 weeks) Milder highs, but depression often more severe and frequent
Cyclothymia Hypomanic symptoms Depressive symptoms Chronic (≥2 years), less severe but persistent mood cycling

Based on DSM-5 diagnostic criteria. A qualified mental health professional is required for accurate diagnosis.

Recognizing Mood Episodes

Bipolar disorder is characterized by two main types of mood episodes: manic (or hypomanic) episodes and depressive episodes. Recognizing the symptoms of each is crucial for early intervention.

🔥 Manic Episode Symptoms

  • Feeling unusually "high," elated, or irritable
  • Decreased need for sleep (feeling rested after 3 hours)
  • Racing thoughts, rapid speech
  • Being easily distracted
  • Increased goal-directed activity
  • Risky behavior (spending sprees, risky sex, impulsive decisions)
  • Inflated self-esteem or grandiosity

🌧️ Depressive Episode Symptoms

  • Feeling sad, empty, hopeless, or tearful
  • Loss of interest in almost all activities
  • Significant weight loss/gain or appetite changes
  • Sleeping too much or too little
  • Fatigue or loss of energy
  • Feelings of worthlessness or excessive guilt
  • Difficulty thinking, concentrating, or making decisions
  • Thoughts of death or suicide

Hypomania vs. Mania

Hypomania involves the same symptoms as mania but is less severe and shorter in duration (at least 4 days vs. 7 days). While hypomanic episodes don't cause the severe impairment that mania does, they are still a significant change from normal behavior and noticeable to others.

People experiencing hypomania may feel great and highly productive. However, without proper treatment, hypomanic episodes can develop into full mania or severe depression.

Mixed Features

Some people experience "mixed features"—having symptoms of mania and depression at the same time. For example, feeling very energized while also feeling hopeless. Mixed episodes can be particularly dangerous because the combination of high energy and depressive thoughts increases suicide risk.

Treatment Options

Bipolar disorder is a lifelong condition, but symptoms can be managed effectively with the right treatment plan. Treatment typically involves a combination of medication, psychotherapy, and lifestyle modifications.

Medications

Medications are the cornerstone of bipolar treatment. The main categories include:

Medication Class Examples Primary Use
Mood Stabilizers Lithium, Valproate, Carbamazepine Prevent mood episodes, treat mania
Atypical Antipsychotics Quetiapine, Olanzapine, Aripiprazole, Lurasidone Mania, depression, maintenance
Anticonvulsants Lamotrigine Depression prevention, maintenance
Antidepressants SSRIs, SNRIs (used cautiously) Depressive episodes (with mood stabilizer)

⚠️ Antidepressant Caution

Antidepressants used alone can trigger manic episodes in people with bipolar disorder. They should only be prescribed alongside a mood stabilizer or antipsychotic, and under close medical supervision.

Psychotherapy

Therapy, in combination with medication, is highly effective for bipolar disorder:

Other Treatments

Electroconvulsive Therapy (ECT) may be recommended for severe depression or mania that doesn't respond to medications, or when rapid response is needed. Despite its portrayal in media, modern ECT is safe and highly effective.

Living with Bipolar Disorder

With proper treatment and self-management strategies, people with bipolar disorder can lead full, productive lives. Here are evidence-based strategies for maintaining stability:

Lifestyle Strategies

Recognizing Early Warning Signs

Learning to recognize your personal warning signs of an impending episode is one of the most valuable skills you can develop:

When you notice warning signs, contact your treatment team immediately. Early intervention can prevent a full episode.

📱 Mood Tracking Apps

Apps like Daylio, eMoods, and Bearable can help you track mood patterns, sleep, medication adherence, and potential triggers—making it easier to share information with your care team.

What Causes Bipolar Disorder?

The exact cause of bipolar disorder is unknown, but research suggests it results from a combination of factors:

Genetics

Bipolar disorder tends to run in families. If you have a parent or sibling with bipolar disorder, you have a higher risk (about 10%) of developing it, compared to 2-3% in the general population. However, most people with a family history never develop the condition.

Brain Structure and Function

Research using brain imaging shows subtle differences in brain structure and activity in people with bipolar disorder. These differences may help explain why treatments work and guide future research.

Environmental Triggers

While genetics create vulnerability, environmental factors can trigger episodes:

Getting Diagnosed

There is no blood test or brain scan for bipolar disorder. Diagnosis is based on a comprehensive evaluation by a mental health professional, which typically includes:

Challenges in Diagnosis

Bipolar disorder is often misdiagnosed, particularly as unipolar depression (because people often seek help during depressive episodes, not manic ones). On average, it takes 10 years from symptom onset to receive a correct diagnosis.

Be sure to tell your doctor about any past episodes of elevated mood, increased energy, or uncharacteristic behavior—even if they felt good at the time.

Ongoing Research

Scientists are actively researching bipolar disorder to improve diagnosis and treatment:
