Causes

By Mayo Clinic staff

It's not known specifically what causes cyclothymia. As with many mental disorders, research shows that it may result from a combination of:

  • Heredity — cyclothymia tends to run in families
  • Your body's biochemical processes, such as changes in brain chemistry
  • Environment
