Overview

Bipolar disorder, formerly called manic depression, is a mental health condition that causes extreme mood swings that include emotional highs (mania or hypomania) and lows (depression).

When you become depressed, you may feel sad or hopeless and lose interest or pleasure in most activities. When your mood shifts to mania or hypomania (less extreme than mania), you may feel euphoric, full of energy or unusually irritable. These mood swings can affect sleep, energy, activity, judgment, behavior and the ability to think clearly.

Episodes of mood swings may occur rarely or multiple times a year. While most people will experience some emotional symptoms between episodes, some may not experience any.

Although bipolar disorder is a lifelong condition, you can manage your mood swings and other symptoms by following a treatment plan. In most cases, bipolar disorder is treated with medications and psychological counseling (psychotherapy).

Symptoms

There are several types of bipolar and related disorders. They may include mania or hypomania and depression. Symptoms can cause unpredictable changes in mood and behavior, resulting in significant distress and difficulty in life.

• Bipolar I disorder. You've had at least one manic episode that may be preceded or followed by hypomanic or major depressive episodes. In some cases, mania may trigger a break from reality (psychosis).

• Bipolar II disorder. You've had at least one major depressive episode and at least one hypomanic episode, but you've never had a manic episode.

• Cyclothymic disorder. You've had at least two years — or one year in children and teenagers — of many periods of hypomania symptoms and periods of depressive symptoms (though less severe than major depression).

• Other types. These include, for example, bipolar and related disorders induced by certain drugs or alcohol or due to a medical condition, such as Cushing's disease, multiple sclerosis or stroke.

Bipolar II disorder is not a milder form of bipolar I disorder, but a separate diagnosis. While the manic episodes of bipolar I disorder can be severe and dangerous, individuals with bipolar II disorder can be depressed for longer periods, which can cause significant impairment.

Although bipolar disorder can occur at any age, typically it's diagnosed in the teenage years or early 20s. Symptoms can vary from person to person, and symptoms may vary over time.

​

Mania and hypomania

Mania and hypomania are two distinct types of episodes, but they have the same symptoms. Mania is more severe than hypomania and causes more noticeable problems at work, school and social activities, as well as relationship difficulties. Mania may also trigger a break from reality (psychosis) and require hospitalization.

Both a manic and a hypomanic episode include three or more of these symptoms:

• Abnormally upbeat, jumpy or wired

• Increased activity, energy or agitation

• Exaggerated sense of well-being and self-confidence (euphoria)

• Decreased need for sleep

• Unusual talkativeness

• Racing thoughts

• Distractibility

• Poor decision-making — for example, going on buying sprees, taking sexual risks or making foolish investments

​

Major depressive episode

A major depressive episode includes symptoms that are severe enough to cause noticeable difficulty in day-to-day activities, such as work, school, social activities or relationships. An episode includes five or more of these symptoms:

• Depressed mood, such as feeling sad, empty, hopeless or tearful (in children and teens, depressed mood can appear as irritability)

• Marked loss of interest or feeling no pleasure in all — or almost all — activities

• Significant weight loss when not dieting, weight gain, or decrease or increase in appetite (in children, failure to gain weight as expected can be a sign of depression)

• Either insomnia or sleeping too much

• Either restlessness or slowed behavior

• Fatigue or loss of energy

• Feelings of worthlessness or excessive or inappropriate guilt

• Decreased ability to think or concentrate, or indecisiveness

• Thinking about, planning or attempting suicide

​

Other features of bipolar disorder

Signs and symptoms of bipolar I and bipolar II disorders may include other features, such as anxious distress, melancholy, psychosis or others. The timing of symptoms may include diagnostic labels such as mixed or rapid cycling. In addition, bipolar symptoms may occur during pregnancy or change with the seasons.

​

Diagnosis

To determine if you have bipolar disorder, your evaluation may include:

• Physical exam. Your doctor may do a physical exam and lab tests to identify any medical problems that could be causing your symptoms.

• Psychiatric assessment. Your doctor may refer you to a psychiatrist, who will talk to you about your thoughts, feelings and behavior patterns. You may also fill out a psychological self-assessment or questionnaire. With your permission, family members or close friends may be asked to provide information about your symptoms.

• Mood charting. You may be asked to keep a daily record of your moods, sleep patterns or other factors that could help with diagnosis and finding the right treatment.

• Criteria for bipolar disorder. Your psychiatrist may compare your symptoms with the criteria for bipolar and related disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association.

​

Diagnosis in children

Although diagnosis of children and teenagers with bipolar disorder includes the same criteria that are used for adults, symptoms in children and teens often have different patterns and may not fit neatly into the diagnostic categories.

Also, children who have bipolar disorder are frequently also diagnosed with other mental health conditions such as attention-deficit/hyperactivity disorder (ADHD) or behavior problems, which can make diagnosis more complicated. Referral to a child psychiatrist with experience in bipolar disorder is recommended.

​

Treatment

Treatment is best guided by a medical doctor who specializes in diagnosing and treating mental health conditions (psychiatrist) who is skilled in treating bipolar and related disorders. You may have a treatment team that also includes a psychologist, social worker and psychiatric nurse.

Bipolar disorder is a lifelong condition. Treatment is directed at managing symptoms. Depending on your needs, treatment may include:

• Medications. Often, you'll need to start taking medications to balance your moods right away.

• Continued treatment. Bipolar disorder requires lifelong treatment with medications, even during periods when you feel better. People who skip maintenance treatment are at high risk of a relapse of symptoms or having minor mood changes turn into full-blown mania or depression.

• Day treatment programs. Your doctor may recommend a day treatment program. These programs provide the support and counseling you need while you get symptoms under control.

• Substance abuse treatment. If you have problems with alcohol or drugs, you'll also need substance abuse treatment. Otherwise, it can be very difficult to manage bipolar disorder.

• Hospitalization. Your doctor may recommend hospitalization if you're behaving dangerously, you feel suicidal or you become detached from reality (psychotic). Getting psychiatric treatment at a hospital can help keep you calm and safe and stabilize your mood, whether you're having a manic or major depressive episode.

The primary treatments for bipolar disorder include medications and psychological counseling (psychotherapy) to control symptoms, and also may include education and support groups.
