Bipolar disorder (also called manic-depressive illness) is a mood disorder in which periods of abnormally elevated and energized mood — known as mania — alternate with periods of low mood, or depression. It is not simply a matter of ordinary mood swings; it is a medical condition that genuinely affects daily life and social functioning. Roughly 2 to 2.5% of people worldwide receive this diagnosis, making it more common than many people realize. With consistent treatment, it is entirely possible to live a stable and fulfilling life.
What Is Bipolar Disorder?
People with bipolar disorder typically experience depressive episodes far more often, and for much longer, than manic episodes — anywhere from 3.7 to 37 times as frequently. Although it can look similar to ordinary depression, the depressive phase of bipolar disorder tends to begin at a younger age, typically in the teens or twenties, and is more likely to include emotional swings, irritability, impulsive behavior, or hypersomnia (sleeping much more than usual) and overeating.
What Are the Symptoms?
Manic Episode Symptoms
When mood is unusually elevated or irritable and activity levels are markedly increased for at least one week, and three or more of the following are present, a manic episode may be occurring.
- Inflated self-esteem or an unfounded sense of grandiosity
- Feeling that little or no sleep is needed (for example, feeling rested after only three hours)
- Talking more than usual, or feeling unable to stop talking
- Racing thoughts, or ideas tumbling over one another so quickly that speech becomes jumbled
- Being easily distracted by minor or irrelevant things
- Taking on many new projects or feeling physically restless and unable to sit still
- Engaging impulsively in risky or pleasurable activities that are likely to cause regret later — excessive spending, reckless sexual behavior, or unwise investments, for example
Depressive Episode Symptoms
When five or more of the following are present for at least two weeks (and at least one of them must be either symptom 1 or symptom 2), a depressive episode may be occurring.
- Depressed mood for most of the day, nearly every day
- Markedly diminished interest or pleasure in all, or almost all, activities
- Significant weight loss without dieting, or weight gain; or decreased or increased appetite
- Insomnia or sleeping much more than usual
- Slowed thinking and movement, or conversely, agitation and restlessness
- Fatigue and loss of energy
- Feelings of worthlessness or excessive guilt
- Difficulty concentrating or making decisions
- Recurrent thoughts of death or suicide
If you are having thoughts of suicide: Please call the Suicide Prevention Hotline at 109 right now (available 24 hours a day, free of charge, in Korean). You do not have to face this alone. Since 2024, the previous suicide prevention lines 1393 and 129 have been merged and now operate together under the single number 109.
The Varied Course of the Illness
Bipolar disorder does not always follow a neat, predictable pattern of alternating mania and depression. A depressive phase may last anywhere from a few weeks to several years; a manic episode may be over in a week; and sometimes both states occur simultaneously in what is called a mixed episode. The pattern varies considerably from one person to another.
What Causes It?
Bipolar disorder results from a combination of factors rather than a single cause.
- Genetic factors: Having a close family member with bipolar disorder increases the likelihood of developing it yourself. However, a genetic predisposition does not guarantee the condition will develop; the interaction with environmental factors matters greatly.
- Neurotransmitter imbalances in the brain: Disruptions in the balance of chemical messengers in the brain can trigger symptoms.
- Stress and circadian rhythm disruption: Disrupted sleep patterns or major life stress can trigger an episode or worsen an existing one.
- Hormonal changes in women: Depressive episodes are more likely to occur just before menstruation, after childbirth, and during menopause. These episodes are sometimes labeled “premenstrual syndrome,” “postpartum depression,” or “menopausal depression.”
- Season and sunlight: Depressive episodes are more common during the late autumn and early winter months when daylight hours are short. In Korea, the rainy season (July) can also be a vulnerable period.
Frequently Asked Questions
Q. How do I know whether I might have bipolar disorder? If you experience severe depressive episodes, abnormal elevation of mood, or extreme irritability lasting more than a few days — and these affect your daily life — it is a good idea to consult a mental health professional. Self-diagnosis based on symptoms alone is difficult, and a professional evaluation is needed. You may also find it helpful to read Anxiety Disorder: Symptoms, Treatment, and Mental Health Support for Foreigners.
Q. I sometimes go very quiet and then suddenly become very talkative. Could that be a symptom? Changes in how much someone talks are indeed a recognized symptom, but that alone is not enough to make a diagnosis. A professional needs to evaluate the full pattern of behavioral changes over time.
Q. How common is bipolar disorder? Bipolar I disorder affects approximately 1% of the general population, and Bipolar II disorder affects approximately another 1%. When the broader spectrum of bipolar-related conditions is included, roughly 2 to 2.5% of the population is estimated to have some form of bipolar disorder. It is more common in daily life than most people assume.
Q. Can bipolar disorder be overcome? It is more accurately described as a condition to be managed well rather than cured outright. That said, many people receive treatment and go on to lead full personal and professional lives. Throughout history, a number of celebrated artists and scientists lived with bipolar disorder. Please do not be discouraged.
Q. Should antidepressants be avoided? Antidepressants used on their own tend to be less effective for bipolar disorder, and in some patients they can actually worsen symptoms. Always consult a psychiatrist before taking any antidepressant medication, and do not take antidepressants on your own without a prescription and professional guidance.
Q. How can I support someone close to me who has bipolar disorder? The most important thing you can do is to be there to help them access professional care. If they bring up thoughts of suicide, acknowledge their pain with empathy first, and then help connect them with professional help as quickly as possible.
Treatment
Medication
Medication is the cornerstone of treatment for bipolar disorder. The two main categories used are:
- Mood stabilizers: Lithium, valproate, and similar medications. These are among the most established treatments available and work to prevent extreme swings in mood.
- Atypical antipsychotics: Quetiapine, risperidone, aripiprazole, olanzapine, and others. These help restore the balance of neurotransmitters in the brain.
Even when symptoms improve, it is essential to continue taking medication consistently over the long term to prevent relapse. It is important for both the patient and their family to understand and accept this.
Psychotherapy and Social Support
Combining medication with cognitive therapy or family therapy helps reduce the likelihood of relapse. Identifying sources of stress in everyday life and maintaining a regular daily routine are also important parts of treatment. You can find guidance on managing sleep patterns in Sleep Disorders: Causes, Prevention, Self-Assessment, and Finding Help.
Daily Life Tips
The following habits can help ease symptoms and prevent relapse.
- Get enough sleep; where possible, go to bed and wake up at the same time each day.
- Keep a regular daily schedule.
- During seasons with reduced sunlight (late autumn to early winter, and the rainy season in Korea), make a point of getting morning sunlight.
- For women: recognize the likelihood of mood dips before menstruation and proactively ask family or friends for support.
- Make a conscious effort to reduce excessive pressure or ambition that leads to stress.
- Avoid substances that affect mood, such as alcohol or appetite suppressants, and avoid binge eating.
