Depressed: sharing stories and supporting those with stories of dysthymia (persistent depressive disorder) or depression.
There are no known biological causes that apply consistently to all cases of dysthymia, which suggests diverse origin of the disorder. However, there are some indications that there is a genetic predisposition to dysthymia: “The rate of depression in the families of people with dysthymia is as high as fifty percent for the early-onset form of the disorder”. Other factors linked with dysthymia include stress, social isolation, and lack of social support.
In a study using identical and fraternal twins, results indicated that there is a stronger likelihood of identical twins both having depression than fraternal twins. This provides support for the idea that dysthymia is in part caused by heredity.
