Understanding Atypical Depression
Despite its name, atypical depression is actually quite common, especially in women. It is characterized by excessive weight gain and an increased desire to sleep for long periods of time. The patient suffering from atypical depression is overly sensitive to criticism and rejection. He or she may feel lethargic and have a marked decrease in energy. Atypical depression differs from major depression in that the patient's mood may temporarily lift under certain circumstances. It has been speculated that atypical depression may be caused by specific incidents, or genetic or environmental factors.
Hypothyroidism
A study published in the Journal of the American Medical Association titled "Hypothyroidism and Depression" found a correlation between hypothyroidism and atypical depression. The thyroid hormone known as T3 can have a major influence on serotonin, a neurotransmitter responsible for feelings of well-being. Researchers have speculated that the low levels of T3 caused by hypothyroidism can cause atypical depression.
Medications
Certain drugs such as high blood pressure medications, sleeping pills and birth control pills may cause atypical depression.
Chronic Illness
Certain illnesses, such as cancer, heart disease, diabetes or stroke can cause atypical depression.
Devastating Incidents
The death of a friend, lover or family member, the end of a relationship, the loss of a job or a traumatic event can cause atypical depression. A study performed at CUNY titled "New York Airline Workers in the Aftermath of 9/11/01" found that depression was the most common disorder amongst airline workers who were laid off as a result of the attacks.
