Identifying the different types of bipolar disorder

Bipolar disorder is a complex condition with several types, including Bipolar 1 and Bipolar 2.

Despite its complexities, it is important to remember that each person's experience with bipolar disorder is unique. Symptoms can range from feeling highly energised and motivated to feeling irritable and angry.

Bipolar 1 disorder

The clearest characteristic of Bipolar 1 disorder is significant mood swings, which can involve periods of elation and low moods, including depression.

Bipolar 1 is also characterised by full manic episodes, defined as a period of elevated, expansive, or irritable mood lasting at least one week, accompanied by increased energy and activity. A manic episode may also include:

In addition to manic episodes, people with Bipolar 1 can also experience major depressive episodes.

A major depressive episode is a depressed mood or loss of interest or pleasure, as well as four or more additional symptoms, during the same two-week period. These symptoms may include weight changes, slowed thoughts and movement, fatigue, worthlessness or guilt, difficulty thinking or making decisions, suicidal thoughts, or changes in sleep patterns (insomnia or hypersomnia).

The types of episodes associated with Bipolar 1 disorder

When a person experiences a manic episode, Bipolar 1 may be diagnosed. It is also possible to experience hypomanic episode, depressive episodes, and periods of feeling neutral.

Manic episode

Manic episodes generally last around one week. They are characterised by someone being extremely happy, or low and irritable. Manic episodes can come with the following changes in behaviour:

Major depressive episode

A major depressive episode can last for at least two weeks. During this period, a person experiences intense sadness, and will most likely lose interest in activities they would usually enjoy. Symptoms generally include:

Bipolar 2 disorder

Recognising Bipolar 2 can sometimes be challenging as it may be mistaken for recurring depression due to the alternating experience of major depressive episodes and hypomania, a mild form of mania.

Hypomanic episodes typically last around four days, shorter than the manic episodes in Bipolar 1. During a hypomanic episode, symptoms are usually not severe enough to cause significant impairment in daily functioning and are not accompanied by psychotic symptoms.

Substance/medication-induced bipolar disorder

Recent studies have revealed that some people undergoing antidepressant treatment, such as medication or electroconvulsive therapy, may develop manic or hypomanic episodes that persist beyond the effect of the treatment.

Illegal drugs like cocaine or amphetamines can also trigger medication-induced bipolar disorder. Symptoms may include elevated mood that persists even after the substance has cleared the body.

Diagnosing substance and medication-induced bipolar disorder is complex and requires a skilled psychiatrist. If you are experiencing negative reactions while taking medication, it's important to seek help quickly.

How is bipolar disorder managed?

Bipolar disorder is a lifelong condition. However, symptoms can be managed effectively, and quality of life can be improved significantly. Management generally includes a combination of medication and talking therapy. Bipolar disorder affects everyone differently, so treatment may differ from person to person.

Medication

Medication can be effective at stabilising mood swings and preventing episodes of mania or depression. Doctors may prescribe different medications depending on each person’s unique situation and needs.

Talking therapy

Psychotherapy can help people manage symptoms, identify triggers, and develop coping strategies. Although a range of talking therapies can be effective in treating Bipolar disorder, Cognitive Behavioural Therapy (CBT) is the most used approach.

Some other therapies may include:
