In simple words: Cyclothymic disorder is a less severe type of bipolar disorder.It involves periods of feeling very happy and energetic (hypomania) mixed with periods of feeling down (mild depression). These mood swings happen frequently for at least two years (one year for children and teens) and disrupt daily life.

Cyclothymic disorder, also known as cyclothymic personality disorder, is a chronic mood disorder characterized by numerous periods of hypomanic symptoms and periods of depressive symptoms that do not meet the full criteria for a major depressive episode or a manic episode.These mood swings must persist for at least two years in adults (one year in children and adolescents), with periods of euthymia (normal mood) lasting less than two months. The symptoms significantly impact social, occupational, or other important areas of functioning.The disorder is distinguished from bipolar disorder by the less severe nature of the mood episodes.

Example 1: A 20-year-old college student presents with fluctuating moods over the past two years, including periods of increased energy, sociability, and decreased need for sleep (hypomania), alternating with periods of low mood, fatigue, and difficulty concentrating (mild depression). These episodes never meet criteria for full mania or major depression., A 45-year-old individual reports a long history (over five years) of unpredictable mood swings. They experience periods of elevated mood with increased productivity and impulsivity (hypomania) followed by periods of irritability, low energy, and feelings of worthlessness (mild depression).The intensity and duration of these episodes do not meet the criteria for bipolar I or II disorder., A 15-year-old teenager exhibits significant mood instability, characterized by periods of heightened energy, impulsiveness, and talkativeness (hypomania), followed by periods of sadness, loss of interest in activities, and social withdrawal (mild depression).This pattern has persisted for over a year.

Detailed psychiatric history including duration and frequency of mood episodes, symptom severity, impact on functioning, family history of mood disorders, substance use history, and relevant psychosocial factors.Results of any relevant physical and laboratory examinations to rule out medical causes.Assessment using standardized diagnostic criteria (DSM-5).

** Cyclothymic disorder can be challenging to diagnose, particularly in the early stages. It is important to differentiate it from other mood disorders and rule out substance use or medical conditions that could be contributing to the symptoms.Longitudinal monitoring is often necessary to assess the course of the illness and determine appropriate treatment.
