What is bipolar disorder?

Bipolar disorder (formerly known as manic-depressive illness or manic depression) is a lifelong mood disorder and mental health condition that causes intense shifts in mood, energy levels, thinking patterns and behavior. These shifts can last for hours, days, weeks or months and interrupt your ability to carry out day-to-day tasks.

There are a few types of bipolar disorder, which involve experiencing significant fluctuations in mood referred to as hypomanic/manic and depressive episodes. However, people with bipolar disorder aren’t always in a hypomanic/manic or depressive state. They also experience periods of normal mood, known as euthymia.

Manic episodes

A key feature of bipolar I disorder is manic episodes. To meet the criteria for bipolar I disorder, you must have had at least one manic episode in your life for at least a week with or without ever experiencing a depressive episode.

Mania is a condition in which you have a period of abnormally elevated or irritable mood, as well as extreme changes in emotions, thoughts, energy, talkativeness and activity level. This highly energized level of physical and mental activity and behavior is a change from your usual self and is noticeable by others.

People who are in manic states may indulge in activities that cause them physical, social or financial harm, such as suddenly spending or gambling extreme amounts of money or driving recklessly. They also occasionally develop psychotic symptoms, such as delusions and hallucinations, which can cause difficulties in distinguishing bipolar disorder from other disorders such as schizophrenia or schizoaffective disorder.

People with certain types of bipolar such as bipolar II disorder experience hypomania, which is a less severe form of mania. It doesn’t last as long as manic episodes and it doesn’t interfere with daily functioning as much.

Depressive episodes

During a depressive episode, you experience a low or depressed mood and/or loss of interest in most activities, as well as many other symptoms of depression, such as:

• Tiredness.
• Changes in appetite.
• Feelings of worthlessness and hopelessness.
