Cyclothymia (/ˌsaɪkləˈθaɪmiə/, siy-kluh-THIY-mee-uh), also known as cyclothymic disorder, psychothemia / psychothymia,[5] bipolar III,[6] affective personality disorder[7] and cyclothymic personality disorder,[8] is a mental and behavioural disorder[9] that involves numerous periods of symptoms of depression and periods of symptoms of elevated mood.[3] These symptoms, however, are not sufficient to indicate a major depressive episode or a manic episode.[3] Symptoms must last for more than one year in children and two years in adults.[3]
The cause of cyclothymia is unknown.[2] Risk factors include a family history of bipolar disorder.[3] Cyclothymia differs from bipolar disorder in the fact that major depression and mania are not found.[3]
Treatment is generally achieved with counseling and mood stabilizers such as lithium.[4] It is estimated that 0.4–1% of people have cyclothymia at some point in their lives.[3] The disorder's onset typically occurs in late childhood to early adulthood.[3] Males and females are affected equally often.[3]
