Cyclothymia is a mood disorder marked by ongoing mood swings, with periods of elevated mood or irritability and periods of mild depressive symptoms. It is sometimes considered a potential early or less severe form of bipolar II disorder.
The exact cause of cyclothymia, also known as cyclothymic disorder, is not fully understood. However, changes in neurotransmitters, traumatic experiences, and genetics may play a role, and the condition can affect men and women equally.
Cyclothymia should be diagnosed by a psychiatrist or psychologist based on a detailed evaluation of symptoms over time. Treatment may involve psychotherapy and, in some cases, medications prescribed by a psychiatrist to help manage mood symptoms, such as mood stabilizers.
Cyclothymia symptoms
The main symptoms of cyclothymia are:
-
Chronic mood changes
-
Periods of agitation and euphoria followed by irritability and sadness, or vice versa
-
Racing thoughts
-
Lack of motivation
-
Insomnia or excessive sleep
-
Increased or decreased energy
-
Denial that something is wrong
-
Decreased appetite
Because these mood changes are often seen as part of the person’s personality, cyclothymia may go undiagnosed. This can lead to significant psychological distress, as the person experiences frequent mood swings.
Although cyclothymia is not always associated with major disruption to a person’s life, it can cause significant emotional strain. In these cases, medication may be needed to help stabilize mood and should be recommended by a psychiatrist.
Confirming a diagnosis
Cyclothymia should be diagnosed by a psychologist or psychiatrist based on symptoms, medical history, and diagnostic criteria such as those outlined in the DSM-5. This assessment may take place during psychotherapy sessions or during a dedicated mental health evaluation.
According to the American Psychiatric Association’s DSM-5-TR criteria, cyclothymic disorder involves chronic mood fluctuations with hypomanic and depressive symptoms that do not meet the full criteria for bipolar I disorder, bipolar II disorder, or major depressive disorder.
The clinician also considers symptom severity, impact on daily functioning, and whether another condition, such as bipolar disorder, may better explain the symptoms.
Treatment options
Cyclothymia can be treated with psychotherapy, including cognitive-behavioral therapy (CBT) or interpersonal therapy. The goal is to reduce mood fluctuations, improve negative thought patterns, and support healthier social functioning.
In some cases, medication may be recommended, particularly when symptoms significantly affect daily life. According to the FDA, there are no medications specifically approved for cyclothymia, although psychiatrists may prescribe medications approved for related mood disorders, such as mood stabilizers or certain antipsychotics, based on individual needs.
In addition, maintaining a healthy lifestyle, including a balanced diet, regular sleep, and stress management, is recommended to support overall well-being.
