Explanation:
Bipolar disorder is a chronic mental illness characterized by more or less drastic swings in mood. The person experiences episodes of emotional highs called mania or hypomania followed by depression. Often, one of the two states - manic or depressive - predominates over the other, although both tend to alternate with periods of some normality. Mania is the state of mind characterized by euphoria, combined with a higher level of activity, can lead to high-risk behaviors, which can have serious consequences. In the hypomanic episode, the mood is elevated and there is also increased activity and less need for sleep. The depressive phase is characterized by a loss of interest in all or almost all daily activities, lasts for most of the day and can last up to six months. It deteriorates the quality of life of those who suffer from it and, many times, it interferes in their daily functioning, both in the academic and work environment, as well as in the family and social sphere.
