Bipolar disorders are mental health conditions characterized by periodic, intense emotional states affecting a person’s mood, energy, and ability to function. These periods, lasting from days to weeks, are called mood episodes. Mood episodes are categorized as manic/hypomanic episodes when the predominant mood is intensely happy or irritable, or depressive episodes, when there is an intensely sad mood or the ability to experience joy or pleasure disappears. People with bipolar disorder generally have periods of neutral mood as well. When treated, people with bipolar disorder can lead full and productive lives.
While people without bipolar disorder may also experience mood fluctuations, mood changes that are part of commonly lived experience typically last hours rather than days and are not accompanied by extreme changes in behaviour or changes in functioning, such as difficulties with daily routines and social interactions. Bipolar disorder can disrupt a person’s relationships with loved ones and cause difficulty in working or going to school.
There are three types of bipolar disorder. All three types involve clear changes in mood, energy, and activity levels. These moods range from periods of extremely “up,” elated, irritable, or energized behavior (known as manic episodes) to very “down,” sad, indifferent, or hopeless periods (known as depressive episodes). Less severe manic periods are known as hypomanic episodes.
Sometimes a person might experience symptoms of bipolar disorder that do not match the three categories listed above, and this is referred to as “other specified and unspecified bipolar and related disorders.”
Bipolar disorder is often diagnosed during late adolescence (teen years) or early adulthood. Sometimes, bipolar symptoms can appear in children. Although the symptoms may vary over time, bipolar disorder usually requires lifelong treatment. Following a prescribed treatment plan can help people manage their symptoms and improve their quality of life.
People with bipolar disorder experience periods of unusually intense emotion and changes in sleep patterns and activity levels, and engage in behaviours that are out of character for them—often without recognizing their likely harmful or undesirable effects. These distinct periods are called mood episodes. Mood episodes are very different from the person’s usual moods and behaviours. During an episode, the symptoms last every day for most of the day. Episodes may also last for longer periods, such as several days or weeks.
Symptoms of a Manic Episode
Symptoms of a Depressive Episode
Sometimes people have both manic and depressive symptoms in the same episode, and this is called an episode with mixed features. During an episode with mixed features, people may feel very sad, empty, or hopeless while at the same time feeling extremely energized.
A person may have bipolar disorder even if their symptoms are less extreme. For example, some people with bipolar II disorder experience hypomania, a less severe form of mania. During a hypomanic episode, a person may feel very good, be able to get things done, and keep up with day-to-day life. The person may not feel that anything is wrong, but family and friends may recognize changes in mood or activity levels as possible symptoms of bipolar disorder. Without proper treatment, people with hypomania can develop severe mania or depression.
The two main types of treatment for bipolar disorder are medication and talking therapies. The exact combination of treatments offered will depend on whether you’re managing a current mood episode, or managing your mental health in the longer term.
