Step-by-step explanation:
Cyclothymia, also known as dysthymia or persistent depressive disorder, is a mood disorder characterized by chronic fluctuations in mood, including periods of mild depression and hypomania. The diagnosis of cyclothymia requires the presence of these mood fluctuations for at least two years in adults, and one year in children or adolescents. However, it is important to note that the symptoms should not meet the criteria for a major depressive episode, manic episode, or hypomanic episode during this period.
For example, if someone experiences depressive episodes lasting for a few weeks, followed by a period of increased energy and heightened mood (hypomanic episode) for several days, and this pattern continues consistently for at least two years, then it may be indicative of cyclothymia.
It is recommended to consult with a mental health professional, such as a psychiatrist or psychologist, to receive a proper diagnosis and appropriate treatment.
