Difference between Dysthymia and Major Depressive Disorder?

Dysthymia and major depressive disorder (MDD) are both depressive disorders, but they have different symptoms and severity.

Dysthymia is a chronic, low-grade form of depression that lasts for at least two years. Symptoms of dysthymia include:

* Depressed mood most of the day, more days than not

* Lack of interest in activities that used to be enjoyable

* Changes in appetite or sleep

* Tiredness or low energy

* Low self-esteem

* Difficulty concentrating or making decisions

* Feelings of hopelessness or worthlessness

Major depressive disorder is a more severe form of depression that lasts for at least two weeks. Symptoms of MDD are similar to those of dysthymia, but they are more intense and can interfere with a person's ability to function. Symptoms of MDD include:

* Depressed mood most of the day, nearly every day

* Loss of interest in activities that used to be enjoyable

* Significant changes in appetite or sleep

* Restlessness or slowed down thinking and movement

* Fatigue or loss of energy

* Feelings of worthlessness or guilt

* Difficulty concentrating or making decisions

* Recurrent thoughts of death or suicide

Dysthymia is often considered to be a less severe form of MDD, but it can still be a debilitating condition. People with dysthymia may have difficulty working, going to school, or maintaining relationships. They may also be at an increased risk for developing other mental health conditions, such as anxiety disorders or substance abuse.

Treatment for dysthymia and MDD typically involves medication, psychotherapy, or a combination of both.
