Atypical depression gets its name because the symptoms of this type of depression differ from many signs of clinical depression. Generally, atypical depression is diagnosed in the late teens or early 20's, earlier than typical depression, through a psychological evaluation that includes examination of the symptoms. Treatment for this type of depression usually consists of medication therapy. Talk therapy is also helpful once medication therapy has been started.
Overeating
Unlike clinical depression where lack of appetite runs rampant, a patient with atypical depression will overeat. Common foods that are craved include sweets and carbohydrates. This may lead to noticeable weight gain. As the person gains weight, her self esteem begins to drop, which may make the symptoms of atypical depression worse. Some people may try to diet as the weight rises.
Hypersomnia
Hypersomnia, which is also known as oversleeping, is a sign of atypical depression. A person may sleep long hours or may need frequent naps. A person with hypersomnia is often difficult to awaken. The need for more sleep may be limited only to periods of depression. This may lead to lethargy and a heavy feeling in the arms and/or legs.
Mood Reactivity
Mood reactivity refers to the way that external events will positively or negatively affect the mood of the person with atypical depression. A person with clinical depression will usually experience persistent sadness; however, a person with atypical depression may experience mild sadness that may abate when positive things happen. On the other hand, when negative events occur, the person may fall deeper into depression. Additionally, he may be extremely sensitive to the comments of others.
