Risk factors

By Mayo Clinic staff

Cyclothymia is thought to be relatively rare, affecting less than 1 percent of the population. But true estimates are hard to pin down because people may be undiagnosed or misdiagnosed as having other mood disorders, such as depression. Cyclothymia typically starts during adolescence or young adulthood. Cyclothymia affects about the same number of men and women.

Factors that may increase the risk of developing cyclothymic disorder include:

  • Having other biological family members with cyclothymia or bipolar disorder
  • Periods of high stress
  • Substance abuse
  • Major life changes, such as the death of a loved one
