Dysthymia
(Dysthymic Disorder)
Pronounced: Dis-thigh-mee-uh
Definition
Dysthymia is similar to depression. However, dysthymia symptoms are milder and can last over two years. It is a mild to moderate depression that may go away during periods of normal mood that last up to two months.
Dysthymia can be treated with medications. Contact your doctor if you think you have this condition.
Causes
The cause of dysthymia is not known. A chemical in the brain called serotonin may play a role. Serotonin helps your brain handle emotions and make judgments. It is also associated with a sense of well-being.
