A combination of antidepressants and cognitive therapies can be helpful in preventing major depressive symptoms from occurring.
Additionally, exercise and good sleep hygiene (e.g., improving sleep patterns) are thought to have an additive effect on treating dysthymic symptoms and preventing them from worsening.
This new condition includes both chronic major depressive disorder and the previous dysthymic disorder.
The reason for this change is that there was no evidence for meaningful differences between these two conditions.
Additionally, cognitive therapies can be effective for working with people with double depression in order to help change negative thinking patterns and give individuals a new way of seeing themselves and their environment.
It has been suggested that the best way to prevent double depression is by treating the dysthymia.
A "double depression" is the occurrence of episodes of major depression in addition to dysthymia.
Double depression occurs when a person experiences a major depressive episode on top of the already-existing condition of dysthymia.
It is difficult to treat, as sufferers accept these major depressive symptoms as a natural part of their personality or as a part of their life that is outside of their control.
As dysthymia is a chronic disorder, sufferers may experience symptoms for many years before it is diagnosed, if diagnosis occurs at all.
As a result, they may believe that depression is a part of their character, so they may not even discuss their symptoms with doctors, family members or friends.
