What is Bipolar Disorder?

[trp_language language=”en_US”]

Bipolar disorder, also known as bipolar affective disorder and, less commonly, manic depression, is a mental health condition that causes dramatic changes in mood that, in turn, affect people’s ability to carry out day-to-day tasks.

It is characterized by serious mood swings between depression and mania that last several weeks or months. These mood swings are more extreme than those experienced by most people.^[1]

According to the World Health Organization (WHO), bipolar disorder currently affects 60 million people around the world.^[2]

Bipolar disorder affects men and women equally. It is most common for bipolar disorder symptoms to begin during someone’s late teens or early adult years, but children and older adults can also develop bipolar disorder.

There is no known cure for bipolar disorder. People with the condition are likely to experience recurrences throughout their life which, if left untreated, can be highly disruptive and potentially lead to hospitalization and even suicide. However, there are effective treatments that can reduce the frequency and severity of mood swings.^[3]

Problems with substance abuse are common among people with bipolar disorder. Among those with the condition, approximately 42 percent also misuse alcohol, 20 percent also misuse cannabis and 17 percent also misuse other illegal drugs.^[4]

People with bipolar disorder may self-medicate with alcohol or illegal drugs* to ease distress caused by their symptoms. However, misusing alcohol and drugs can have serious social and health consequences.^[5]

Symptoms

People with bipolar disorder experience mood swings between mania and depression that last several months.

If you think that you or someone you know might have a health condition, please check with your doctor Find my Doctor to find out more about your symptoms.

Mania

Manic episodes can feel like an intense state of wellbeing, with unusual reserves of energy. However, the manic phase of bipolar disorder can cause people to lose touch with day-to-day reality and with how other people feel. After a manic episode, people can feel embarrassed or ashamed about their behavior and unable to manage plans that were made while experiencing mania.

Hypomania

The symptoms of hypomania are similar to mania but less extreme. Episodes of hypomania last for a few days rather than weeks or months, as is common with mania. It is unusual to have any psychotic symptoms with hypomania.

Depression

During an episode of depression, a person may feel very low, worthless or tearful. This can potentially lead to thoughts of suicide or even attempted suicide.

Periods of extremely low mood or depression can last for at least two weeks, with symptoms interfering with day-to-day life.

The contrast between the ‘high’ of mania or hypomania may make an episode of depression even harder to cope with.

Mixed features

Mixed features, also known as mixed episodes or mixed states, are when people feel symptoms of depression and mania or hypomania at the same time.

Psychotic symptoms

In very severe cases, symptoms of psychosis may develop. In a psychotic episode, a person loses touch with reality. They may see, hear or believe things that the people around them do not.

Types of bipolar disorder

There are various types of bipolar disorder, sometimes known as bipolar spectrum disorders (BSDs). These include:

Bipolar I disorder

Bipolar I disorder, pronounced as bipolar 1 disorder and sometimes abbreviated as BPI, is defined by:^[6][7]

• Manic episodes that last at least seven days
• It is common to experience periods of depression, as well, though not in every case
• Without treatment, a manic episode may last up to six months
• Manic episodes may be severe enough to require hospitalization

Bipolar II disorder

Bipolar II disorder, pronounced as bipolar 2 disorder and sometimes abbreviated as BPII is defined by:^[6][7]

• More than one episode of severe depression
• Episodes of hypomania, that are less severe than those mania episodes seen in Bipolar I disorder

Cyclothymic disorder

The cyclothymic disorder also referred to as cyclothymia, is similar to bipolar disorder. It is characterized by emotional highs and lows that are not as severe as a bipolar disorder but can still affect day-to-day life.

The cyclothymic disorder often goes undiagnosed, but in less than half of cases it can develop into bipolar disorder.^[8]

Good to know: Multiple episodes of mania, hypomania or depression experienced within a year is termed rapid cycling. According to John Hopkins Medicine, the average person with bipolar disorder will experience nine episodes over a lifetime. Someone with rapid cycling bipolar disorder may experience four or more episodes a year.^[9]

Around 10 to 20 percent of people with bipolar disorder experience rapid cycling. It is more common in people with bipolar II disorder and also more commonly experienced by women.^[10]

What causes bipolar disorder?

The causes of bipolar disorder are not yet fully understood. The lifetime prevalence (LTP) of bipolar disorder is around 3 to 5 percent. LTP describes the proportion of people who have experienced a condition in their lifetime.

There appears to be a genetic link, as the chance of developing bipolar disorder is greater if a family member is also affected.^[11] If one parent has bipolar disorder, there is a 25 percent chance a child will develop it. If both parents have bipolar disorder there is a chance of up to 50 percent that a child will develop bipolar disorder.^[12]

Bipolar disorder may be caused by a problem with the way the brain controls mood. This is why medication is often used to control symptoms.

High-stress situations and life-changing events may trigger an episode of depression or mania.^[13]

How is bipolar disorder diagnosed?

There is no medical or blood bipolar disorder test. A doctor or other mental health practitioner will make a diagnosis based on conversations with the person affected.^[14]

Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) bipolar disorder criteria for diagnosing bipolar disorder require at least one episode of mania or one episode of hypomania and one episode of depression.^[7]

International Statistical Classification of Diseases and Related Health Problems, tenth revision (ICD-10) bipolar disorder criteria for diagnosing bipolar disorder requires two or more episodes of prolonged and significantly disturbed mood, consisting of mania, or hypomania and depression. The ICD-10 also classifies episodes of only mania or hypomania as bipolar.^[15]

It is possible for a person with bipolar disorder to experience an initial episode of depression, and they will therefore not be diagnosed with bipolar disorder. In such cases, treatment with antidepressants may trigger a first episode of mania.

If you think that you or someone you know might have a health condition, please check with your doctor Find my Doctor to find out more about your symptoms.

Treatment & Management

There is no known cure for bipolar disorder. Treatment aims to stabilize mood and prevent episodes of mania and depression from becoming extreme and allow the individual to live without disruption.

Bipolar disorder medications

Medications are a common way of treating bipolar disorder. Some people with the condition need a combination of medications to control mood swings in the most effective way for them.^[7][16][17]

Lithium

Lithium has been used to stabilize moods for over 50 years, though how it works isn’t fully known. It is mainly used for preventing and stabilizing mania by evening out mood swings, although it can also be prescribed to treat depression.^[18]

Getting the right dose for each person is very important. If the dose is too low, the drug won’t be effective. If the dose is too high, lithium becomes toxic. People taking lithium need regular blood tests to check the dosage and to ensure the kidneys and thyroid are working properly.

Side effects of normal dosage can include:^[19][20]

• Feeling thirsty
• Urinating more often than usual
• Nausea
• Feeling tired
• Gaining weight
• Slightly shaky hands
• Hypothyroidism and goiter – enlarged thyroid gland – can develop with long-term use

If there is too much lithium in the body, side effects can include:

• Feeling very thirsty
• Diarrhea or vomiting
• Noticeable shaking of limbs
• Muscle twitches
• Being confused

The amount of lithium in the body is affected by how much liquid and salt the person takes in. Drinking plenty of non-alcoholic fluids and avoiding a low salt diet is recommended.

Lithium use is declining in the United States because of concerns over its side effects and the availability of medications like valproate. However, it is still considered an effective treatment.^[21]

Taking lithium reduces the chances of having a manic episode within the next year by 30 to 40 percent.

Anticonvulsant medication

Valproate is an anticonvulsant medication that was originally developed to treat epilepsy. It is increasingly used to treat bipolar disorder as a mood stabilizer, particularly in the United States. It is not yet clear how the drug works.

Valproate is used to treat mania, rapid cycling, and mixed episodes. It is sometimes prescribed along with lithium, as there is a suggestion that the two work more effectively together.^[22]

Valproate can cause damage to a developing fetus, and should not be taken by women of childbearing age.^[23]

Other side effects may include:

• Nausea
• Feeling shaky
• Diarrhea
• Increased appetite and associated weight gain
• Changes to levels of ammonia and platelets in the blood

Carbamazepine and lamotrigine are anticonvulsants that are also used as mood stabilizers. Carbamazepine is thought to be more effective at treating rapid cycling than lithium and causes fewer side effects. Lamotrigine is generally prescribed for treating bipolar II disorder.^[16]

Antipsychotic medication

Antipsychotic medications, such as olanzapine and quetiapine, are used to treat mania. They can also be used in conjunction with mood stabilizers to prevent mania from occurring.^[24]

Antipsychotic medications help by treating bipolar disorder with psychotic features, such as hearing voices, delusions, and racing thoughts. They can also help to prevent extreme mood swings and, in some cases, can be used to treat severe depression.^[17]

These medications work by blocking dopamine in the brain. Side effects may include:

• Feeling sleepy and sluggish
• Weight gain
• Lack of interest in sexual activity
• Increased chance of developing diabetes
• High doses can cause limbs to be stiff and shaky

Antidepressants

Antidepressant medications are used to treat moderate to severe episodes of depression.

For some people, there is a risk that treatment with antidepressants alone can trigger an episode of mania or make rapid cycling more likely. For this reason, it’s recommended that antidepressants, such as fluoxetine^[25], should be prescribed alongside a mood stabilizer.^[26]

SSRI antidepressants can take two to six weeks to start affecting mood. They are thought to work by increasing levels of serotonin in the brain.

There are many potential side effects when using SSRIs, though most wear off after a few weeks. These side effects include:^[17][25]

• Anxiety
• Nausea
• Upset stomach
• Dizziness
• Not sleeping enough or sleeping too much
• Low sex drive

It is important not to stop taking SSRIs too soon so as to prevent a recurrence of depression. A course of six to nine months is usually recommended, though in more severe cases, it may be advisable to continue taking SSRIs for longer. A doctor should be consulted before stopping treatment with SSRIs.^[27][28]

Psychological treatments for bipolar disorder

In between episodes of mania or hypomania and depression, cognitive-behavioral or psychotherapy treatments can help. Psychotherapy usually takes place in sessions of one hour over periods of several months.^[28]

Cognitive behavioral therapy (CBT)

Cognitive-behavioral therapy is a form of talking therapy that focuses on how thoughts and beliefs affect feelings and behavior. CBT teaches participants coping skills to recognize and deal with problems.^[29]

For people with bipolar disorder, CBT can help improve awareness of behavior, compliance with treatment plans, and day-to-day coping skills. When used alongside medication, a study of 19 randomized control trials found that CBT is effective in reducing the relapse rate and the severity of symptoms.^[30]

Self monitoring

Learning to recognize signs of moods swinging out of control is an important step in managing bipolar disorder. Recognizing early signs can lead to intervention and prevent full episodes of mania and depression, and avoid potential hospitalization.

Keeping a food diary is helpful to track long-term mood changes, as well as possible triggers.

Other forms of psychotherapy for bipolar disorder

Psychoeducation can help by providing more information about bipolar disorder to the person with the condition, as well as their family and friends.^[31]

Led by a therapist, group psychoeducation brings together people with similar experiences to share knowledge about how bipolar disorder can affect behavior and how to manage symptoms.

Family therapy can help by working together as a family to strengthen relationships, identify risks and develop support skills.

Other treatments for bipolar disorder

There are other potential treatments for bipolar disorder if medication and psychotherapeutic interventions are not successful, or if the condition is extreme.

Electroconvulsive therapy (ECT)

Electroconvulsive therapy is a treatment that sends an electrical current through the brain to trigger an epileptic seizure. The electricity is administered under general anesthetic and with the use of muscle relaxants, so the body does not convulse.^[32]

ECT is only advised for rapid, short-term relief of severe depression, mania, or psychosis, where other interventions have failed and/or when the condition is considered life-threatening.

ECT causes memory loss, which is usually short-term but can be very disorienting.

New treatments

There is ongoing research into new mood-stabilizing drugs. Other, non-medication therapies, are also being investigated, including vagal nerve stimulation, transcranial magnetic stimulation, and light therapy.

Self care in the management of bipolar disorder

As well as monitoring day-to-day behavior for signs of mood changes, the knowledge gained from such monitoring can be used to avoid triggering an episode of mania or depression.^[33]

It can help to have someone to confide in. Close relationships with people who understand the condition and the individual’s experience and trigger points can be useful as a support network.

Too much activity can trigger a manic episode, so it’s helpful to maintain a balance between work and activity, and relaxation and fun.

Stress and bipolar disorder

Stress is a common trigger, and avoiding highly stressful situations is recommended. However, it’s not possible to avoid all stress, so a useful tool may be to learn relaxation techniques or take advice on handling stress from a qualified therapist.^[34][35]

Healthy lifestyle

There is no specific diet recommended for bipolar disorder. However, maintaining a healthy diet will help with overall wellness.^[36][37] This includes:

• Eating a balance of foods rich in nutrients, such as fruits, vegetables, pulses, whole grains, fish, eggs, low-fat meat, nuts and seeds
• Avoiding food that is high in saturated and trans fats, such as red meat, as well as simple carbohydrates such as refined sugar

Lithium can affect salt levels in the body, so care should be taken not to eat too much or too little.^[19]

Caffeine may contribute to a manic or hypomanic episode by disrupting normal sleep patterns.^[38]

Exercising for 20 minutes, three times a week, helps to maintain fitness. Exercise also releases endorphins into the brain, which improve mood.^[39]

Bipolar disorder in women

The presentation and course of bipolar disorder differ in men and women.

The following features of bipolar disorder tend to be more common in women than in men:^[40][41]

• Later age of onset
• Bipolar II disorder
• Seasonal pattern of mood disturbance
• Depressive symptoms
• Rapid cycling
• Mixed states / features
• Additional medical and psychiatric disorder conditions, particularly thyroid disease, eating disorders, migraine and anxiety disorders
• Delayed diagnosis and treatment

Women with bipolar disorder tend to have more depressive symptoms and different accompanying conditions than men. There is a high risk of symptoms recurring after giving birth and during menopause. Bipolar disorder in women also correlates with an increased risk of sexually transmitted diseases, weight gain, unplanned pregnancies, and cardiovascular disease.

Gender is not thought to affect response to mood-stabilizing medication, though treatment can pose a risk to the developing fetus in pregnant women. Pregnancy does not protect from nor exacerbate bipolar disorder, so many women require continuation of medication during this time. The time after giving birth, the so-called postpartum period, however, does increase the risk of onset and recurrence of bipolar disorder.

Pregnancy and bipolar disorder

Women with bipolar disorder who are pregnant, or plan to become pregnant, should talk to their doctor to assess whether their medications are suitable and to discuss how to manage mood during and after pregnancy.^[42]

Women of childbearing age should not take valproate. If taken while pregnant, there is a high risk of harm to the developing fetus.^[22]

Lithium is safer than other mood stabilizers to take during pregnancy. There is a low risk to the fetus of developing a heart valve defect during the first three months, but lithium is safe after 26 weeks. Babies should not be breastfed if the mother is taking lithium.^[20]

Postpartum illnesses are more common for women with bipolar disorder than for the general population. Postpartum depression and postpartum psychosis are both serious conditions that could affect a woman’s ability to take care of herself and/or her baby.^[43]

Postpartum depression

Around 25 percent of women with bipolar disorder who give birth will experience postpartum depression.^[43]

Postnatal depression can start at any point in the first year after birth. As well as the usual symptoms of depression, postnatal depression symptoms can include difficulty bonding with the baby and disturbing thoughts about causing the baby harm.^[44]

Postpartum psychosis

Around 25 percent of women with bipolar disorder who give birth will experience postpartum psychosis. Women who have previously had a severe postpartum illness, and women who have a mother or sister who experienced a severe postpartum illness, are at even higher risk.^[43]

Symptoms generally begin in the first few days after birth, though they can develop up to six months later. Symptoms are similar to psychosis, including hallucinations and delusions.^[45]

Bipolar disorder in men

The presentation and course of bipolar disorder differ between men and women.

The following features of bipolar disorder tend to be more common in men than in women:^[46][47]

• Manic symptoms
• Excessive use of alcohol, but also other illicit substances
• Worse adherence to medication regimen

Bipolar disorder in children and teenagers

Usually, symptoms of bipolar disorder first appear in teens around the ages of 15 to 19, though signs can be seen in younger children.

The symptoms for mania, hypomania, and depression in bipolar disorder are similar to those in adults, although children and teens may behave more erratically. Moods may change more rapidly than in adults, and children may express mania and hypomania as temper tantrums and physical aggression.

See our resource on signs of bipolar disorder for more information about bipolar disorder in children, teenagers, and young adults.

The American Academy of Child and Adolescent Psychiatry urges caution in looking for signs of bipolar disorder in toddlers and children under six years old.^[48]

If you think that a child in your care might have a health condition, please check with your doctor Find my Doctor to find out more about their symptoms.

## What is Bipolar Disorder?



Bipolar disorder, formerly known ⁤as manic⁣ depression, is a serious mental illness that causes extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). ‌These ⁣mood swings can‌ interfere with a person’s ability to work, study, sleep, eat, and maintain relationships.



**Keywords:**‍ Bipolar disorder, mood swings, mania, hypomania, depression



### Symptoms of Bipolar Disorder



**Mania or Hypomania:**



* Feeling euphoric, ⁤overly happy, or irritable

* Racing thoughts and rapid speech

* Increased energy⁤ and ⁢activity levels

* Decreased need for sleep

* Impulsive behavior, such as ​spending sprees or reckless sexual activity

* Inflated self-esteem ‌or​ grandiose delusions



**Depression:**



* Feeling sad, hopeless, or worthless

* Loss of interest in activities that ​were once enjoyable

* Changes in appetite or​ sleep patterns

* Fatigue or lack ⁢of energy

* Difficulty concentrating or making decisions

* Suicidal‌ thoughts or behaviors



### Types of Bipolar Disorder



There are several types of bipolar disorder, including:



* **Bipolar I Disorder:** Characterized by at least one episode of ⁢full-blown mania that ⁢may or may not⁤ be accompanied ‌by depressive ⁤episodes.

* ⁣**Bipolar II Disorder:** Characterized by at least one hypomanic episode and one major⁣ depressive episode.

* **Cyclothymic Disorder:** Characterized by repeated periods of hypomania and depressive symptoms ‌that do not meet ​the criteria for full-blown⁣ episodes.



### Causes of Bipolar Disorder



The exact ‍cause of bipolar disorder is ​unknown, but it is thought to⁤ be caused by a combination of factors,‍ including:



* **Genetics:** Bipolar disorder‌ tends to run in families, suggesting a genetic component.

* **Neurochemical imbalances:**⁢ People with bipolar⁣ disorder have abnormal levels of certain neurotransmitters, such⁣ as dopamine and ⁢serotonin, in​ their brains.

* **Environmental factors:** Stressful events, such as trauma ‌or loss, can trigger episodes‍ of bipolar disorder in those who are genetically ‍predisposed.



### Treatment for Bipolar Disorder



Treatment for bipolar‍ disorder typically involves a combination of medications and psychotherapy.



**Medications:**



* **Mood stabilizers:** Lithium,‍ valproate,⁣ and lamotrigine are commonly used to prevent or reduce mood swings.

* **Antipsychotics:** These medications are used to treat mania or hypomania.

* ‍**Antidepressants:** These​ medications may be used ⁤to treat depression in ‌people ‌with bipolar disorder, but they should be used with caution as they can trigger manic‌ episodes.



**Psychotherapy:**



* ‌**Cognitive behavioral ⁣therapy (CBT):** This therapy helps people ⁣with⁣ bipolar disorder to identify and change negative ‍thought patterns⁤ and behaviors that‍ contribute to their mood​ swings.

* **Family-focused therapy:** ​This therapy⁢ involves helping family members learn about‌ bipolar disorder and​ how to support their loved one.

* **Interpersonal and social‍ rhythm ⁢therapy (IPSRT):** This therapy focuses on regulating sleep-wake cycles and improving social functioning.



### Outlook for ⁤People with Bipolar Disorder



With proper treatment, people with bipolar disorder can live full and productive lives. However, it is important to note that this is a lifelong condition ⁢that requires ongoing management.



**If you or‍ someone you know is⁣ experiencing symptoms⁤ of bipolar disorder, it​ is important‍ to seek⁢ professional help immediately.**
