Dysthymia is more common in women than in men. Other factors that may increase your chance of dysthymia include:
- Family history of major depression or dysthymia
- Chronic mental or physical illness
- Chronic stress
- Environmental factors
People who have dysthymia may also experience episodes of major depression.
Dysthymia may be difficult to differentiate from depression due to many overlapping symptoms, which may include:
You will be asked about your symptoms and medical history. A physical and psychological exam will be given.
Your doctor may refer you to a specialist for further evaluation. Tests may be done to look for medical causes like thyroid problems or anemia.
Talk with your doctor about the best treatment plan for you. Treatment may include one or more of the following:
