Question: What is Cyclothymic Disorder or Cyclothymia?

Answer: According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), cyclothymic disorder - also called cyclothymia - is "a chronic, fluctuating mood disturbance involving numerous periods of hypomanic symptoms and numerous periods of depressive symptoms." Simply translated, this means it is a long-term condition where the person's moods cycle between hypomania - a "high" that can be mild to fairly severe but does not include delusions, hallucinations or other psychotic features - and depression, also mild to fairly severe but not incapacitating or suicidal.

Here's what goes into a diagnosis of cyclothymia:

  • Symptoms do not qualify as major manic or major depressive episodes
  • Symptoms never ease up for more than two months
  • There hasn't been a manic, mixed or depressive episode in the first two years of symptoms
  • Another disorder is not responsible for symptoms
  • Symptoms are not caused by a drug or general medical condition
