Dysthymia or Persistent Depressive Disorder

Persistent Depressive Disorder (DSM-V) or dysthymia (ICD-10) is a less severe but longer lasting form of depression, lasting several years. A combination of antidepressants and psychotherapy are often useful in treating dysthymia, although symptoms can be integrated into the personality of the patient due to the long duration of the disorder, making treatment problematic.
