Bipolar disorder — sometimes called manic-depressive disorder — causes mood swings that range from of the lows of depression to the highs of mania. When you become depressed, you may feel sad or hopeless and lose interest or pleasure in most activities. When your mood shifts in the other direction, you may feel euphoric and full of energy. Mood shifts may only occur only a few times a year, or as often as several times a day. In some cases, bipolar disorder causes symptoms of depression and mania at the same time.
Alternative Names of Bipolar Disorder are: Manic depressive disorder.

Complications of Bipolar Disorder

Left untreated, bipolar disorder can result in serious problems that affect every area of your life. These can include:

• Problems related to substance and alcohol abuse
• Legal problems
• Financial problems
• Relationship troubles
• Isolation and loneliness
• Poor work or school performance
• Frequent absences from work or school
• Suicide

Causes of Bipolar Disorder

Several factors seem to be involved in causing and triggering bipolar episodes:

• Biological differences. People with bipolar disorder appear to have physical changes in their brains. The significance of these changes is still uncertain but may eventually help pinpoint causes.
• Neurotransmitters. An imbalance in naturally occurring brain chemicals called neurotransmitters seems to play a significant role in bipolar disorder and other mood disorders.
• Hormones. Imbalanced hormones may be involved in causing or triggering bipolar disorder.
• Inherited traits. Bipolar disorder is more common in people who have a blood relative (such as a sibling or parent) with the condition. Researchers are trying to find genes that may be involved in causing bipolar disorder.
• Environment. Stress, abuse, significant loss or other traumatic experiences may play a role in bipolar disorder.

Signs & Symptoms of Bipolar Disorder

The exact symptoms of bipolar disorder vary from person to person. For some people, depression causes the most problems; for other people manic symptoms are the main concern. Symptoms of depression and symptoms of mania or hypomania may also occur together. This is known as a mixed episode.

Manic phase of bipolar disorder

Signs and symptoms of the manic or hypomanic phase of bipolar disorder can include:

• Euphoria
• Extreme optimism
• Inflated self-esteem
• Poor judgment
• Rapid speech
• Racing thoughts
• Aggressive behavior
• Agitation or irritation
• Increased physical activity
• Risky behavior
• Spending sprees or unwise financial choices
• Increased drive to perform or achieve goals
• Increased sex drive
• Decreased need for sleep
• Inability to concentrate
• Careless or dangerous use of drugs or alcohol
• Frequent absences from work or school
• Delusions or a break from reality (psychosis)
• Poor performance at work or school

Depressive phase of bipolar disorder

Signs and symptoms of the depressive phase of bipolar disorder can include:

• Sadness
• Hopelessness
• Suicidal thoughts or behavior
• Anxiety
• Guilt
• Sleep problems
• Low appetite or increased appetite
• Fatigue
• Loss of interest in daily activities
• Problems concentrating
• Irritability
• Chronic pain without a known cause
• Frequent absences from work or school
• Poor performance at work or school

Other signs and symptoms bipolar disorder

Signs and symptoms of bipolar disorder can also include:

• Seasonal changes in mood. As with seasonal affective disorder (SAD), some people with bipolar disorder have moods that change with the seasons. Some people become manic or hypomanic in the spring or summer and then become depressed in the fall or winter. For other people, this cycle is reversed — they become depressed in the spring or summer and manic or hypomanic in the fall or winter.
• Rapid cycling bipolar disorder. Some people with bipolar disorder have rapid mood shifts. This is defined as having four or more mood swings within a single year. However, in some people moods shifts occur much more quickly, sometimes within just hours.
• Psychosis. Severe episodes of either mania or depression may result in psychosis, a detachment from reality. Symptoms of psychosis may include false but strongly held beliefs (delusions) and hearing or seeing things that aren't there (hallucinations). In some people, sudden psychosis (a psychotic break) is the first sign of bipolar disorder.

Symptoms in children and adolescents

Instead of clear-cut depression and mania or hypomania, the most prominent signs of bipolar disorder in children and adolescents can include explosive temper, rapid mood shifts, reckless behavior and aggression. In some cases, these shifts occur within hours or less — for example, a child may have intense periods of giddiness and silliness, long bouts of crying and outbursts of explosive anger all in one day. Changing sleep patterns are also a common indicator of childhood bipolar disorder.

Diagnosis of Bipolar Disorder

When doctors suspect someone has bipolar disorder, they typically do a number of tests and exams. These can help rule out other problems, pinpoint a diagnosis and also check for any related complications. These can include:

• Physical exam. This may involve measuring your height and weight; checking your vital signs, such as heart rate, blood pressure and temperature; listening to your heart and lungs; and examining your abdomen.
• Lab tests. These may include blood and urine tests. These tests can help identify any physical problems that could be causing your symptoms.
• Psychological evaluation. A doctor or mental health provider 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 and possible episodes of mania or depression.
• Mood charting. To identify exactly what's going on, your doctor may have you keep a daily record of your moods, sleep patterns or other factors that could help with diagnosis and finding the right treatment.

Treatments of Bipolar Disorder

Bipolar disorder requires lifelong treatment, even during periods when you feel better. Treatment is usually guided by a psychiatrist skilled in treating the condition. You may have a treatment team that also includes psychologists, social workers and psychiatric nurses. The primary treatments for bipolar disorder include medications; individual, group or family psychological counseling (psychotherapy); or education and support groups.

• Hospitalization may be needed if you are behaving dangerously, you feel suicidal or you become detached from reality (psychotic).
• Initial treatment generally involves taking medications to balance your moods right away. Once your symptoms are under control, you'll work with your doctor to find the best long-term treatment.
• Continued treatment (maintenance treatment) is used to manage bipolar disorder on a long-term basis. 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.
• Substance abuse treatment may be necessary if you have problems with alcohol or drugs. Otherwise, it can be very difficult to manage bipolar disorder.

Prevention of Bipolar Disorder

There's no sure way to prevent bipolar disorder. However, getting treatment at the earliest sign of a mental health disorder can help prevent bipolar disorder or other mental health conditions from worsening. If you've been diagnosed with bipolar disorder, some strategies can help prevent minor episodes from becoming full-blown episodes of mania or depression:

• Pay attention to warning signs. Addressing symptoms early on can prevent episodes from getting worse. You and your caregivers may have identified a pattern to your bipolar episodes and what triggers them. Call your doctor if you feel you're falling into an episode of depression or mania. Involve family members or friends in watching for warning signs.
• Avoid drugs and alcohol. Even though you may feel better, using alcohol or street drugs makes your symptoms more likely to come back.
• Take your medications exactly as directed. Medications can have unwanted side effects, and you may feel unhappy about having a mental health condition that requires lifelong treatment. During periods when you feel better, you may be tempted to stop treatment. This can have immediate consequences — you may become very depressed, feel suicidal, or go into a manic or hypomanic episode. If you think you need to make a change, call your doctor.
• Check first before taking other medications. Call the doctor who's treating you for bipolar disorder before you take medications prescribed by another doctor. Sometimes other medications trigger episodes of bipolar disorder or may interfere with medications you're already taking to treat bipolar disorder.

When to seek Medical Advice

If you have any symptoms of depression or mania, see your doctor or mental health provider. Bipolar disorder doesn't get better on its own. Getting treatment from a mental health provider with experience in bipolar disorder can help you get your symptoms under control. Many people with bipolar disorder don't get the treatment they need. Despite the mood extremes, people with bipolar disorder often don't recognize how much their emotional instability disrupts their lives and the lives of their loved ones. And if you're like some people with bipolar disorder, you may enjoy the feelings of euphoria and cycles of being more productive. However, this euphoria is always followed by an emotional crash that can leave you depressed, worn out — and perhaps in financial, legal or relationship trouble. If you're reluctant to seek treatment, confide in a friend or loved one, a health care professional, a faith leader or someone else you trust. They can help you take the first steps to successful treatment.

If you have suicidal thoughts

Suicidal thoughts and behavior are common among people with bipolar disorder. If you or someone you know is having suicidal thoughts, get help right away. Here are some steps you can take:

• Contact a family member or friend.
• Seek help from your doctor, a mental health provider or other health care professional.
• Call a suicide hot line number — in the United States, you can reach the toll-free, 24-hour hot line of the National Suicide Prevention Lifeline at 800-273-8255 to talk to a trained counselor.
• Contact a minister, spiritual leader or someone in your faith community.

When to get emergency help

If you think you may hurt yourself or attempt suicide, call 911 or your local emergency number immediately. If you have a loved one who has harmed himself or herself, or is seriously considering doing so, make sure someone stays with that person. Take him or her to the hospital or call for emergency help.
