Bipolar Disorder Symptoms, Diagnosis and Treatment

Bipolar disorder causes major shifts in mood, energy, activity, and behavior^1,5. These shifts go beyond the usual highs and lows of daily life¹.

The changes can affect sleep, judgment, work, close bonds, and daily tasks^1,7. The condition may last for years or occur in separate episodes¹.

Symptoms may ease between episodes, but long-term care is often needed^1,6. Treatment often pairs medicine with talk therapy and social support^4,5.

This guide explains the main signs, diagnosis, treatment choices, and safety steps.

Mood episodes cause clear changes from a person’s usual mood and actions¹. The changes also affect energy, thought, sleep, or activity^1,5.

Symptoms often occur most of the day during an episode¹. They may last one or two weeks, or sometimes longer¹.

Episodes can harm work, school, close bonds, and daily life^1,5. Severe episodes may also lead to unsafe acts or hospital care^1,6.

Some people return to a stable mood between episodes¹. Others have frequent shifts or signs between episodes^1,7.

Doctors consider symptoms over the course of the illness when diagnosing bipolar disorder^1,2. The main types have different patterns:

Bipolar II is not a mild form of bipolar I. People with bipolar II may spend longer periods with depression.

Mixed features mean high and low mood signs occur in one episode^7,8. For example, racing thoughts may occur during a mood episode⁴.

Rapid cycling means four or more mood episodes within one year^1,7. These may include mania, hypomania, or major depression.

The signs of bipolar disorder can vary between people and over time^1,7. Doctors look for a clear change from the person’s usual state¹.

Length, impact, and safety risks also matter during an assessment^1,2.

Mania means a very high or irritable mood with much more drive^1,5. It also causes a clear rise in activity¹.

If a manic episode occurs, these signs may appear:

Mania causes more harm to daily life than hypomania. It may disrupt work, school, social life, or close bonds.

Some manic episodes include psychosis, which means losing touch with what is real. A person may hold fixed beliefs that are not true⁵.

Hypomania means similar signs that are less severe and less disruptive^5,7. It does not cause psychosis or a marked loss of daily function⁸.

Hypomania may feel pleasant or useful to the person^1,8. This can make the change hard to spot^1,8.

Friends or family may notice the shift first^1,8. A severe period of depression may follow hypomania^1,4.

A major depressive episode brings low mood or a deep loss of interest^5,7. Signs last most days for at least two weeks⁵.

If a depressive episode occurs, these signs may appear:

Depression can limit work, school, social life, and close bonds^5,7. It may follow a period that felt active or useful^1,4.

Duration thresholds for some bipolar-related symptoms differ between adults and children or teens. Yet mood patterns in young people may look different.

Some children have fast mood shifts during an episode. Severe changes may stand apart from their usual mood swings.

Depression may appear as anger, hostility, or a short temper. Signs may also overlap with attention or behavior problems.

This overlap can make the diagnosis harder. A child psychiatrist may help assess complex signs in a young person^6,8.

The exact cause of this condition is not known⁴. Genes, brain function, and the person’s setting may each play a part⁴.

Risk is higher when a close family member has the condition⁴. Stress or past trauma may also raise risk⁴.

These risk factors cannot confirm a diagnosis. A trained doctor must complete a full review^2,8.

A clinical diagnosis comes from a skilled review, not one lab result. No blood test, body marker, or brain scan confirms this condition^2,8.

No single bipolar disorder test can rule it in or out^2,8. Doctors study the length, strength, and timing of past episodes¹.

Four or more episodes of mania or depression within a year is called rapid cycling¹. The person’s full mood history is more useful than one current symptom^1,2.

During the assessment, a doctor may ask about these areas:

With permission, close friends or family may share what they noticed. Their views can help when hypomania was hard to see^1,8.

A doctor may also ask the person to keep a mood chart. This record can track mood, sleep, and other daily changes.

A doctor may perform a physical exam and order lab tests^1,6. These steps look for health problems that could cause the symptoms^1,6.

The tests do not confirm bipolar disorder^2,8. Thyroid disease can cause signs that look like mood episodes¹.

Some prescribed drugs may copy or worsen mood symptoms¹. Street drugs and other substances can have similar effects¹.

New bipolar-like signs later in life need a careful review⁸. Brain and memory disorders can cause similar signs in older adults.

Many people first seek care for depression rather than hypomania^1,2. Hypomania may feel good, so it may not seem worth reporting¹.

Bipolar depression and other major depression share the same broad diagnosis rules. Doctors must ask about all past high mood periods.

Psychosis may cause confusion with schizophrenia¹. In children, attention or behavior problems may hide the mood pattern.

A positive screening result calls for a more detailed assessment^2,8. However, a positive result cannot confirm the diagnosis⁸.

A negative result cannot fully rule it out either⁸. A full interview and lifetime mood history remain vital^2,8.

Treatment can manage current episodes and lower the risk of relapse^5,6. A psychiatrist often guides treatment for bipolar and related disorders.

The plan depends on the current mood episode and past results. Health needs, side effects, and personal wishes also shape the plan^3,5.

Pregnancy plans and the chance of pregnancy must also guide medicine choices⁵.

Mood stabilizers and antipsychotics are common bipolar disorder medications^5,6. A mood stabilizer helps control large shifts in mood.

An antipsychotic may treat mania or support long-term mood control. Some people need more than one medicine^4,6.

Common medicine groups include the following choices:

Finding a helpful plan may take more than one try^4,6. Some medicines need weeks or months to have their full effect.

Lithium requires regular health checks and lab tests⁵. Other medicines may also need blood or health checks.

Some medicines for bipolar disorder can cause sleepiness, muscle spasms, tremors, or weight gain⁵. A doctor should watch for and manage these effects⁵.

Antidepressants can bring on mania or hypomania in some people. Doctors pair them with a mood stabilizer or antipsychotic¹.

Valproate has major risks linked with pregnancy and birth⁵. Pregnant girls and women should not use valproate⁵.

Girls and women who could become pregnant should not use it either⁵. Lithium and carbamazepine should be avoided during pregnancy when possible⁵.

If pregnancy is possible, discuss it with the prescriber. Do not stop or change medicine without medical guidance^4,6.

Psychotherapy means planned talk therapy with a trained care provider. It can build coping skills and support daily function⁸.

Therapy may also help a person follow the care plan⁸. It can teach families how mood episodes may look^4,8.

This knowledge may help people spot changes and seek support^4,8. Therapy usually supports medicine rather than replacing it⁵.

Supported therapy choices include the following approaches:

The best choice depends on the person’s needs and wishes. Alcohol or drug misuse also needs care because it can hinder treatment.

Hospital care may be advised when behavior becomes dangerous. It may also be needed during suicidal thinking or a break from reality.

A hospital can provide safety while the mood becomes more stable. Some people receive intensive daytime care without an overnight stay.

Electroconvulsive therapy uses a mild electrical current while the person sleeps under anesthesia⁴. Its short name is ECT.

Specialists may use ECT for severe illness that has not improved⁴. They may also consider it when treatment must work more quickly⁴.

This may include high suicide risk or catatonia, which means being unresponsive⁴.

Bipolar disorder often needs care even when mood has become stable. Stopping treatment can allow mild changes to become severe episodes.

These steps may support long-term care:

Do not stop or change medicine without speaking with the prescriber^4,6. Stopping may cause withdrawal or bring symptoms back.

A written care plan can guide choices during a future episode. The person, care team, and carer can create it together.

The plan can note past triggers and early signs of relapse. It can also record useful care choices and trusted contacts.

A risk plan should cover these possible problems:

During mania or hypomania, major choices should wait until the episode ends. A calm setting with less noise and activity may help.

Some mood or behavior changes need urgent care. Follow these safety steps:

Lifetime mood patterns are key to an accurate diagnosis^1,2. One sign, current mood, or screening form cannot confirm the condition^2,8.

A full review can guide the choice of medicine and talk therapy^3,5. Regular checks and a clear safety plan support long-term care.

With the right care, people can manage symptoms and lead meaningful lives⁵. Early help matters when mood, judgment, safety, or reality begins to change.
