Dysthymic disorder, or dysthymia, is a type of depression that lasts for at least 2 years. Some people suffer from dysthymia for many years. Their depression is usually mild or moderate, rather than severe. Most people who have dysthymia can't tell for sure when they first became depressed.
Symptoms of dysthymic disorder include a poor appetite or overeating, difficulty sleeping or sleeping too much, low energy, fatigue and feelings of hopelessness. People who have dysthymic disorder may have periods of normal mood that last up to 2 months. Family members and friends may not even know that their loved one is depressed. Even though this type of depression is mild, it may make it difficult for a person to function at home, school or work.
Dysthymic disorder is a fairly common type of depression. It is estimated that up to 4% of people have dysthymia. Dysthymia can begin in childhood or in adulthood. No one knows why, but like most types of depression, it appears to be more common in women.
No one knows for sure what causes dysthymia. It may be related to some changes in the brain that involve a chemical called serotonin (say: seer-uh-tone-in). Serotonin helps your brain handle emotions and make judgments. Other medical problems and ongoing life stress may also play a role.
If you think you have dysthymia, discuss your concerns with your doctor. Your doctor will ask you questions to find out if you have depression and, if so, to identify the type of depression you have. Your doctor may ask you questions about your health and your symptoms, such as how well you're sleeping, if you feel tired a lot, and if you have trouble concentrating. Your doctor will also consider medical reasons that may cause you to feel depressed, such as problems with your thyroid or a certain medicine you may be taking.
Dysthymic disorder can be treated with an antidepressant medicine. This type of drug helps relieve depression. Antidepressants don't cause people to feel "high," and they are not habit-forming.
It may take a number of weeks, or even several months, before you and your doctor know whether an antidepressant is helping you. It is important for you to take the medicine exactly as your doctor tells you. If the antidepressant helps you feel better, you may need to take this medicine for several years. You should continue to take the medicine, even if you begin to feel better. If you stop taking the medicine, you may get depressed again.
Sometimes there are side effects from stopping antidepressant medicine suddenly. If you want to stop taking your medicine, talk to your doctor first. Your doctor can help you avoid side effects from stopping your medicine too quickly.
Sometimes, in addition to taking an antidepressant, patients find that counseling can help them deal with specific problems.
Many doctors believe that combining therapy with medication is the most effective way to treat dysthymia.
